Reverse Charge & Branch Transfer Compliance
Reverse Charge Mechanism and inter-branch supply are two of the most quietly expensive areas of GST compliance — not because the law is unclear, but because businesses routinely miss what they owe themselves.

Reverse Charge Mechanism and inter-branch supply are two of the most quietly expensive areas of GST compliance — not because the law is unclear, but because businesses routinely miss what they owe themselves. RCM shifts the liability to pay tax from the supplier to the recipient — meaning your own accounting team must identify, self-invoice, and pay tax on specified inward supplies, then separately claim it back as input tax credit. Branch transfers between GSTINs of the same legal entity are taxable supplies under GST's 'distinct person' fiction, even though no invoice changes hands with a third party and no money technically leaves the group. At PNPC Global, we have handled RCM and cross-branch GST compliance for multi-location businesses since the regime's 2017 launch — legal service recipients, import-of-service payers, e-commerce sellers, and multi-state manufacturers among them. We do not just remind you an RCM liability exists — we build the identification checklist, the self-invoicing process, the ISD or cross-charge valuation, and the monthly return mapping that keeps you compliant without overpaying or underpaying a single rupee.
What it costs
No hidden charges. The exact figure is set in your engagement letter.
Reverse Charge Mechanism (RCM) is a mechanism under Section 9(3) and Section 9(4) of the CGST Act, 2017 (and the parallel Section 5(3)/5(4) of the IGST Act) under which the liability to pay GST is shifted from the supplier of goods or services to the recipient. Under the normal 'forward charge' mechanism, the supplier collects GST from the buyer and remits it to the government. Under RCM, the recipient itself calculates the tax, pays it directly to the government through the electronic cash ledger, and — if the input is used for business purposes — claims it back as input tax credit in the same or a later return period. Section 9(3) lists specific categories of supply (legal services from an advocate, services of a Goods Transport Agency (GTA) that has not opted to pay forward charge, sponsorship services, services by a director to the company, services by an insurance agent, renting of motor vehicles from non-body-corporate suppliers, and several others notified by the Government from time to time) where RCM applies regardless of the supplier's registration status. Section 9(4) covers supplies received by a registered person from an unregistered supplier of specified categories notified by the Government — this provision has been amended several times since 2017 and currently applies in a narrower, notified form rather than as a blanket rule on all unregistered purchases.
Branch transfer compliance addresses a separate but related GST principle: the 'distinct person' fiction under Section 25(4) of the CGST Act. Where a business is registered in more than one State or Union Territory, each such registration is treated as a distinct person for GST purposes — even though all branches belong to the same PAN-holding legal entity. Consequently, any transfer of goods or supply of services between two GSTINs of the same company (say, from a Chennai head office GSTIN to a Bangalore branch GSTIN) is itself a 'supply' under Schedule I of the CGST Act, attracting GST, even though no consideration changes hands in the ordinary commercial sense. This is commonly called a stock transfer, branch transfer, or inter-branch cross-charge. The valuation of such supplies follows Rule 28 of the CGST Rules — generally the open market value, or, where the recipient is eligible for full input tax credit, the value declared on the invoice is deemed to be the open market value (a significant relief that avoids valuation disputes for fully-credit-eligible recipients).
A closely related mechanism is Input Service Distributor (ISD) registration under Section 20 of the CGST Act. An ISD is a head office (or other office) that receives tax invoices for input services procured centrally — audit fees, software subscriptions, group insurance, common consultancy — on behalf of its branches, and distributes the eligible input tax credit to those branches proportionately, typically based on turnover in the preceding financial year, via an ISD invoice. Following the amendments introduced by the Finance Act 2024 and effective from 1 April 2025, ISD registration has become mandatory (not merely optional) for any entity that has common input services procured for use across multiple distinct-person GSTINs of the same PAN and wishes to distribute that credit — a business can no longer rely purely on informal cross-charge to move common input-service credit between branches where the ISD mechanism is applicable; the cross-charge mechanism under Rule 28 continues to apply for internally-generated services and goods movements between branches, but externally-billed common input services must flow through ISD where distribution across GSTINs is intended.
Getting both RCM and branch-transfer/ISD compliance wrong has a compounding effect precisely because the two frequently interact in the same business: a multi-branch company that imports a professional service centrally (attracting RCM at the head-office GSTIN under the import-of-service rules) must then correctly decide whether that credit is distributed to branches via ISD or retained centrally, while simultaneously identifying and self-invoicing every other Section 9(3)/9(4) RCM supply received directly at each branch. Missing RCM self-invoicing means an unrecorded tax liability that accrues interest at 18% per annum from the original due date, discoverable years later in a departmental audit; missing or mispricing a branch transfer means an understated GSTR-1/GSTR-3B outward supply value that can trigger a demand notice, interest, and — where willful suppression is alleged — penalty up to 100% of the tax involved under Section 74 of the CGST Act.
When RCM and branch-transfer compliance needs dedicated CA attention
Your business regularly engages advocates, arbitrators, or legal counsel for litigation, contracts, or compliance — legal services from an advocate to a business entity are squarely under Section 9(3) RCM
You use Goods Transport Agency (GTA) services for inward or outward freight and the GTA has not opted to pay tax under forward charge — RCM liability falls on the recipient in most such arrangements
Your company pays sitting fees or commission to non-executive/independent directors — director services to the company are notified under RCM regardless of the director's registration status
You import services from an overseas supplier — software licences, consulting, marketing, or SaaS subscriptions billed by a foreign entity — Section 5(3) of the IGST Act brings import of service squarely under RCM for the Indian recipient
You operate GSTINs in more than one State — any movement of goods (inventory, capital assets, samples) or provision of services (shared staff, IT support, management oversight) between those GSTINs is a taxable 'distinct person' supply requiring correct Rule 28 valuation and invoicing
Your head office centrally procures services used across branches — statutory audit fees, ERP/software licences, group insurance, or common facility management — and you need to determine whether ISD registration and credit distribution is required under the post-1 April 2025 mandatory ISD regime
You are unsure whether a recent vendor invoice should have attracted RCM because the vendor is unregistered — the Section 9(4) notified-category rules require careful, current cross-checking rather than a blanket assumption
Your business has been selected for GST departmental audit or scrutiny and RCM self-invoices, branch cross-charge invoices, or ISD distribution records need to be reconstructed or defended
You are setting up a second branch or warehouse in another state for the first time and need the cross-charge, valuation, and ISD framework designed correctly from Day 1 rather than retrofitted after the first inter-branch movement
You want a periodic (monthly/quarterly) reconciliation process that identifies every RCM-liable transaction and every inter-branch movement before the GSTR-3B filing deadline, rather than discovering gaps at year-end audit
When this specific service may not be your priority
Single-GSTIN business with no branches, no import of services, and no transactions with advocates, GTAs, directors, or other Section 9(3)/9(4) notified categories — RCM exposure is likely minimal, though it is still worth a one-time review to confirm
Business that already runs a mature in-house RCM identification and branch cross-charge process with no history of departmental queries — ongoing monthly GST return filing support may be more relevant than a dedicated RCM/branch engagement
Very early-stage business with a single location and no plans for inter-state expansion in the near term — basic GST return filing covers the compliance need until branch or cross-border complexity actually arises
Composition scheme taxpayers — composition dealers cannot claim input tax credit and have a substantially different (and simpler) compliance framework; RCM still technically applies to certain inward supplies but the ITC-recovery dimension that drives most of this service's complexity does not apply the same way
Business whose only 'inter-branch' movement is of exempted or nil-rated goods with no ITC implication and no separate GSTIN involved — confirm this classification with a CA before assuming no compliance obligation exists
RCM and branch-transfer compliance scenarios compared
| Feature | RCM under Sec 9(3) | RCM under Sec 9(4) | Branch Transfer / Cross-Charge (Sec 25(4)) | ISD Distribution (Sec 20) | Import of Services (IGST Sec 5(3)) |
|---|---|---|---|---|---|
| Who pays the tax | Recipient of specified notified services (legal, GTA, director, sponsorship, etc.) | Registered recipient, for narrow notified categories from unregistered suppliers | Transferring GSTIN self-invoices; receiving GSTIN takes credit | ISD-registered office distributes already-paid credit — no fresh tax paid on distribution | Indian recipient of the overseas service |
| Trigger | Nature of the service itself, irrespective of supplier's registration status | Notified category + supplier is unregistered | Any movement of goods or supply of services between two GSTINs of the same PAN | Common input service invoice received centrally, intended for use across GSTINs | Any service received from a supplier located outside India, for a consideration |
| Registration threshold applicability | No threshold — RCM liability applies even to a small/unregistered-adjacent recipient in specified cases; registration under Sec 24 is mandatory for regular RCM payers | No threshold for the notified category once triggered | Applies automatically once a business holds more than one GSTIN under the same PAN | Mandatory ISD registration required (effective 1 April 2025) where common credit is to be distributed | RCM registration/payment obligation can arise even where turnover is below the normal threshold |
| Invoicing requirement | Recipient issues a self-invoice under Section 31(3)(f) where the supplier has not issued a tax invoice | Recipient issues a self-invoice similarly | Transferring GSTIN issues a tax invoice to the receiving GSTIN, valued under Rule 28 | ISD invoice issued by the ISD office to each recipient GSTIN, per Rule 39 distribution formula | Self-invoice by recipient where the foreign supplier does not/cannot issue an Indian GST invoice |
| Valuation basis | Actual consideration paid/payable for the specified service | Actual consideration paid/payable | Open market value under Rule 28; invoice value deemed OMV if recipient is fully credit-eligible | Proportionate to recipient GSTIN's turnover in the relevant period, per Rule 39 | Actual consideration paid or payable, converted to INR at applicable exchange rate |
| ITC eligibility for the payer | Yes, if used for business and not blocked under Section 17(5) | Yes, subject to the same conditions | Yes, for the receiving GSTIN, once the invoice is issued and tax paid by the transferring GSTIN | Recipient GSTIN gets the distributed credit directly — no separate ITC eligibility test at distribution stage | Yes, subject to Section 17(5) restrictions and use in taxable outward supply |
| Return reporting | GSTR-3B Table 3.1(d) (RCM liability) + Table 4(A) ITC claim in the same or later period | Same as Sec 9(3) reporting mechanics | GSTR-1 (outward supply by transferring GSTIN) + GSTR-3B ITC claim by receiving GSTIN | GSTR-6 filed by the ISD monthly, credit reflected in recipient GSTINs' GSTR-2B | GSTR-3B Table 3.1(d) + ITC claim, similar to domestic RCM |
| Common compliance failure PNPC sees | Vendor invoices from advocates/GTAs booked as a normal expense with no RCM self-invoice raised at all | Assuming Sec 9(4) applies broadly to all unregistered vendor purchases when it is in fact narrowly notified | Goods physically moved between branches with only a delivery challan, no tax invoice, no GST paid | Head-office common expenses claimed entirely as HO input credit with no distribution to using branches | Foreign SaaS/subscription invoices paid by card with no RCM self-invoice or GSTR-3B disclosure at all |
This table is a structural comparison for orientation, not a determination of your specific liability. Whether a given transaction attracts Section 9(3), Section 9(4), branch cross-charge, or import-of-service RCM depends on the exact nature of the supply, the registration status of the counterparty, and the current CBIC notifications in force. A transaction-level review by a practising CA is the only reliable way to confirm treatment.
| # | Stage & What PNPC Does | CA Advice Portals Never Give | Timeline |
|---|---|---|---|
| 1 | RCM & Branch Exposure Mapping — full transaction-type review across the business | We review your vendor master, purchase register, and inter-branch ledger against the current CBIC-notified RCM categories (legal services, GTA, director fees, sponsorship, renting of motor vehicles, security services from non-body-corporate suppliers, and others) and against every GSTIN your PAN holds. Most businesses discover at least one missed RCM category in this first review — commonly director sitting fees or foreign SaaS subscriptions. | Week 1 |
| 2 | Vendor & Supply Classification — line-by-line categorisation | Every recurring vendor relationship is tagged: forward charge, Section 9(3) RCM, Section 9(4) RCM (where applicable and currently notified), or import-of-service RCM. We flag GTA vendors specifically, since a GTA's own choice to pay forward charge (via declaration) changes who is liable — a detail portals and general bookkeepers routinely miss. | Week 1–2 |
| 3 | Self-Invoicing Process Design — the mechanics of paying tax to yourself | Under Section 31(3)(f), the recipient must issue a self-invoice for RCM supplies where the supplier does not issue a tax invoice (this is the norm for unregistered suppliers and for cross-border import-of-service transactions). We design the self-invoice template, numbering series, and monthly cut-off process so this is never missed at return-filing time. | Week 2 |
| 4 | Branch/GSTIN Cross-Charge Framework — Rule 28 valuation methodology | For businesses with more than one GSTIN, we determine which inter-branch flows require a tax invoice under Schedule I (stock transfers, shared staff deputation, centrally-provided management services) and set the Rule 28 valuation approach — open market value, or invoice-value-as-OMV where the receiving branch has full ITC eligibility. | Week 2–3 |
| 5 | ISD Registration Assessment — mandatory-ISD determination post 1 April 2025 | We assess whether your head office needs to obtain ISD registration under Section 20 to distribute common input-service credit (audit fees, group software licences, common consultancy) to branch GSTINs. Where mandatory, we handle the ISD registration application and design the Rule 39 turnover-based distribution formula. | Week 3–4 |
| 6 | Reverse-Charge Tax Payment Calendar — cash ledger funding plan | RCM tax must be paid in cash (it cannot be discharged by utilising existing ITC balance) before the corresponding credit can be claimed. We build a monthly cash-flow calendar so the RCM cash outflow is planned for, not a surprise at return-filing time. | Ongoing from Week 4 |
| 7 | GSTR-3B & GSTR-1 Mapping — correct table-wise disclosure | RCM liability is reported in Table 3.1(d) of GSTR-3B and the corresponding ITC claim in Table 4(A)(3). Branch cross-charge outward supply is reported in GSTR-1 by the transferring GSTIN and appears in the receiving GSTIN's GSTR-2B for ITC claim. We verify this mapping every return cycle, not just at year-end. | Every return cycle |
| 8 | ISD Return (GSTR-6) Filing — if ISD registration applies | Where ISD registration is obtained, GSTR-6 must be filed monthly by the 13th of the following month, distributing eligible and ineligible credit separately across recipient GSTINs. We prepare and file this on the applicable calendar. | Monthly, by the 13th |
| 9 | Reconciliation Against GSTR-2B — matching RCM and cross-charge credit claims | We reconcile every RCM self-invoice and every branch cross-charge invoice against the corresponding GSTR-2B entries to confirm the credit trail is unbroken and defensible in the event of departmental scrutiny. | Monthly/Quarterly |
| 10 | Annual Return & Reconciliation (GSTR-9/9C) Alignment | At year-end, RCM liability paid, ITC claimed on RCM, and inter-branch cross-charge values are reconciled against the books and reported consistently in GSTR-9 and, where applicable, GSTR-9C. Mismatches between monthly returns and the annual reconciliation are a common trigger for departmental notices. | Annually, aligned to GSTR-9/9C due dates |
| 11 | Departmental Query & Audit Support | Where the department raises a query on RCM non-payment, under-valuation of branch transfers, or ISD distribution, we prepare the reply, supporting documentation, and — where required — represent the business before the GST officer. | As needed |
| 12 | Process Handover & Internal Training | We train the client's internal accounts team on ongoing identification of RCM-liable transactions and inter-branch cross-charge triggers, so day-to-day bookkeeping catches most items before the monthly CA review — reducing dependence on a full external review every cycle. | Week 4–6, with periodic refreshers |
| 13 | Periodic Regulatory Update Briefing | RCM-notified categories, ISD rules, and GST rate structures are amended by CBIC notification with some regularity. We brief clients whenever a change affects their specific transaction mix, rather than leaving this discovery to a future audit. | As notifications are issued |
Realistic timeline for first-time setup: 3–5 weeks from initial transaction-mapping to a fully operational RCM and branch-transfer compliance process, including ISD registration where applicable (ISD registration itself is typically processed within 3–7 working days on the GST portal once documents are ready). Ongoing monthly reconciliation and return support then runs on the standard GST return cycle.

| Phase | Triggered By | PNPC CA Guidance | Risk If Ignored |
|---|---|---|---|
| Initial Exposure Assessment | Engagement start or first compliance review | Full mapping of RCM-notified categories against the vendor register and of inter-branch flows against all GSTINs held under the PAN. Establishes the baseline of what should have been paid/self-invoiced historically and what needs to start going forward. | Historical RCM liability sitting unrecorded and unpaid, accruing interest at 18% per annum from the original due date, discoverable years later in a departmental audit with penalty exposure. |
| Self-Invoicing Process Go-Live | Baseline assessment complete | Self-invoice numbering series, monthly cut-off, and cash-ledger funding calendar set up. Accounts team trained to flag new RCM-category vendors as they arise. | RCM liability continues to be missed month-on-month; ITC that could have been legitimately claimed timely is instead claimed late or not at all, and cash-flow planning for RCM tax outflow is absent. |
| Branch Cross-Charge Rollout | Business operates or expands to more than one GSTIN | Rule 28 valuation methodology applied consistently to every inter-branch goods movement and service flow. Tax invoices (not just delivery challans) issued for stock transfers between GSTINs. | Understated outward supply value in GSTR-1 for the transferring GSTIN; receiving GSTIN's ITC claim challenged for lack of a valid tax invoice; demand and penalty under Section 74 where suppression is alleged. |
| ISD Registration & Distribution | Common input services procured centrally for multi-GSTIN use | Determination of mandatory ISD applicability post 1 April 2025, ISD registration if required, and monthly GSTR-6 filing distributing eligible credit under the Rule 39 turnover-based formula. | Common credit claimed entirely at head office when it should be distributed proportionately, creating a mismatch that department can challenge; branches lose legitimate credit they were entitled to. |
| Monthly Return Cycle | Every GSTR-1/GSTR-3B filing period | RCM liability and ITC mapped to the correct GSTR-3B tables; branch cross-charge invoices reflected in GSTR-1 and reconciled against the receiving GSTIN's GSTR-2B every cycle. | Table-wise mismatches accumulate silently across periods, making later reconciliation exponentially harder and increasing audit-trigger risk through automated GST portal mismatch flags. |
| Annual Reconciliation | Financial year end, GSTR-9/9C preparation | RCM liability paid and RCM ITC claimed across the year reconciled against books; branch cross-charge total value tied out against inter-branch ledger and stock-transfer records for GSTR-9C certification where applicable. | Annual return figures inconsistent with monthly filings — a leading trigger for departmental scrutiny and best-judgment assessment under Section 62 if the mismatch is unexplained. |
| Regulatory Change Response | CBIC notification amending RCM categories, ISD rules, or valuation methodology | Client briefed on any change affecting their specific transaction mix — RCM-notified category additions/removals, ISD mandate changes, or Rule 28 valuation clarifications — with the compliance process updated accordingly. | Continuing to apply a superseded rule (e.g., treating ISD as optional after it became mandatory, or applying an outdated RCM category list) creates fresh non-compliance even where the original process was sound. |
| Departmental Audit or Query | GST audit selection, DRC-01/ASMT-10 notice, or annual return scrutiny | Full reconstruction of self-invoices, cross-charge invoices, and ISD records for the period in question; drafted reply with supporting documentation; representation before the GST officer where required. | Inadequate or delayed response leads to best-judgment assessment, higher demand than the actual liability, and potential escalation to show-cause proceedings under Section 74. |
What exactly is Reverse Charge Mechanism (RCM) in GST — explained simply?
Normally, the seller collects GST from you and pays it to the government. Under RCM, that responsibility flips — you, the buyer, calculate the GST yourself, pay it directly to the government, and then (if you are entitled to) claim it back as input tax credit. It applies to a specific, notified list of services and situations — not to all your purchases.
Which services are covered under Section 9(3) RCM?
The Government notifies specific categories from time to time. The most commonly encountered ones include: legal services rendered by an advocate or firm of advocates to a business entity; services by a Goods Transport Agency (GTA) that has not opted for forward charge; services by an insurance agent to an insurance company; sponsorship services provided to a body corporate or partnership firm; services supplied by a director of a company to that company; and renting of motor vehicles from a non-body-corporate supplier to a body corporate, among others. This list is not exhaustive and is amended by notification, so it needs periodic verification against current notifications rather than a static internal list.
Does RCM under Section 9(4) apply to every purchase I make from an unregistered supplier?
No — and this is one of the most persistent misunderstandings in GST practice. The original, blanket version of Section 9(4) (covering essentially all purchases from unregistered persons above a threshold) was suspended shortly after GST's 2017 launch and never came back into force in that broad form. What exists today is a narrower, specifically notified version that applies only to certain categories the Government has explicitly notified — most prominently, purchases of certain construction-linked and specified goods/services by promoters in the real estate sector under a dedicated notification. For most ordinary businesses, routine purchases from unregistered vendors do not automatically trigger RCM under Section 9(4) — but this must be confirmed against your specific sector and the current notification, not assumed either way.
What is a self-invoice and why do I need to raise one for RCM supplies?
Under Section 31(3)(f) of the CGST Act, where you receive a supply liable to RCM from a supplier who has not issued you a tax invoice — which is the norm when the supplier is unregistered or located outside India — you, the recipient, must issue a self-invoice recording the transaction, the value, and the tax payable. This self-invoice is your primary evidentiary document for both paying the RCM liability and later claiming the corresponding input tax credit.
Can I use my existing input tax credit balance to pay RCM liability?
No. RCM liability must be discharged in cash — through the electronic cash ledger — and cannot be set off against your existing electronic credit ledger balance, regardless of how much ITC you are carrying forward. Once the cash payment is made and the self-invoice is issued, the corresponding amount can then be claimed as ITC (subject to eligibility), which then sits in your credit ledger for future use against your own output tax liability.
What happens if we simply never realised we owed RCM on legal fees or director sitting fees for the past two years?
The liability does not expire because it was unrecorded — it remains payable along with interest at 18% per annum calculated from the original due date of each missed period. Depending on how the omission is characterised (an inadvertent error versus willful suppression), penalty exposure ranges from a modest amount under Section 73 to up to 100% of the tax involved under Section 74 if suppression or fraud is alleged. The practical, and generally advisable, approach on discovery is voluntary disclosure and payment (with interest) before the department raises it, which materially improves the penalty outcome compared to being caught in a departmental audit.
We import software subscriptions and consulting services from an overseas vendor. Does RCM apply?
Yes, in most cases. Import of service — receipt of a service from a supplier located outside India, for a consideration, where the place of supply is in India — is brought under RCM by Section 5(3) of the IGST Act. The Indian recipient must self-invoice, pay IGST under RCM, and can then claim it back as ITC if the service is used for taxable business purposes and is not blocked under Section 17(5). This applies to SaaS subscriptions, cloud hosting, consulting fees, marketing services, and design work billed by a foreign entity, among others.
What is the 'distinct person' concept and why does it matter for our branches?
Under Section 25(4) of the CGST Act, if a business holds more than one GST registration — even under the same PAN, even for the same legal entity — each registration is legally treated as a separate ('distinct') person for GST purposes. This means any transfer of goods or provision of services between two GSTINs of your own company is a taxable supply, just as if you were transacting with an unrelated third party — even though no external invoice or third-party payment is involved.
How do we value goods or services transferred between our own branches?
Rule 28 of the CGST Rules governs this. The primary basis is 'open market value' — broadly, the price such goods or services would fetch in an arm's-length transaction. However, where the receiving branch is entitled to full input tax credit, the value declared on the invoice is itself deemed to be the open market value — a significant simplification that removes valuation disputes in the common case of a fully-credit-eligible recipient branch. Where the recipient does not have full ITC eligibility (e.g., it makes exempt supplies), a more careful open-market-value determination is required.
Do we need to issue a full tax invoice for stock transferred between our own branches, or is a delivery challan enough?
A tax invoice is required — a delivery challan alone is not sufficient for a taxable inter-branch stock transfer between distinct persons. The delivery challan may accompany the goods in transit under the e-way bill rules, but the underlying GST liability and the receiving branch's entitlement to input tax credit both depend on a properly issued and valued tax invoice being raised by the transferring GSTIN.
What is Input Service Distributor (ISD) registration and do we need it?
An ISD is typically a head office that receives invoices for services procured centrally on behalf of multiple branch GSTINs — statutory audit fees, group software licences, common insurance, shared consultancy — and distributes the input tax credit on those invoices to the branches that actually used the service, proportionate to each branch's turnover in the relevant period, under Rule 39. Following amendments effective 1 April 2025, ISD registration is now mandatory for entities that have such common input services intended for cross-GSTIN distribution — it is no longer purely an optional mechanism where cross-charge could be used interchangeably for externally-billed common services.
What is the difference between ISD credit distribution and branch cross-charge?
ISD distribution moves already-paid input tax credit from a centrally received invoice out to the branches that use the underlying service, via a GSTR-6 filing and an ISD invoice — no fresh GST is generated or paid at the distribution step, only the existing credit is allocated. Cross-charge, by contrast, is a fresh taxable supply between two GSTINs (for internally rendered services like shared staff, management oversight, or IT support that a branch provides to another branch of the same company) — the transferring GSTIN issues a tax invoice, charges GST, and pays it, and the receiving GSTIN claims that GST as fresh ITC. The two mechanisms serve different situations and are not interchangeable for identical transaction types.
How is the ISD distribution amount calculated for each branch?
Rule 39 of the CGST Rules prescribes a turnover-based formula: eligible credit is distributed to each recipient GSTIN in the ratio of that GSTIN's turnover in the relevant period to the aggregate turnover of all recipient GSTINs to which the credit relates, for the same period. Credit attributable exclusively to one GSTIN must be distributed only to that GSTIN; credit attributable to more than one GSTIN is distributed pro-rata by turnover among those GSTINs specifically, not necessarily across every branch in the company.
What GSTR-3B table do we use to report our RCM liability and the corresponding ITC claim?
RCM tax liability is reported in Table 3.1(d) of GSTR-3B (inward supplies liable to reverse charge) in the period the liability arises. The corresponding input tax credit, once eligible, is claimed in Table 4(A)(3) as 'Inward supplies liable to reverse charge'. Both entries should be internally reconciled every period — liability recorded without a matching ITC claim (where eligible) results in an avoidable cash cost, while an ITC claim without a corresponding recorded and paid liability is a mismatch that invites scrutiny.
How is a branch cross-charge invoice reported in GST returns?
The transferring GSTIN reports the cross-charge invoice as an outward supply in its GSTR-1, and pays the applicable GST through its GSTR-3B. The receiving GSTIN sees this reflected as an inward supply in its GSTR-2B (auto-populated from the transferring GSTIN's GSTR-1) and claims the eligible input tax credit in its own GSTR-3B. Because both GSTINs belong to the same company, this exercise is essentially a bookkeeping and cash-neutral-at-group-level transaction — but it must still flow through the standard return mechanics exactly as if the two GSTINs were unrelated parties.
We deputed a senior employee from our Chennai office to help set up our new Bangalore branch for six months. Is this a taxable supply between GSTINs?
Generally, yes — where an employee is deployed from one GSTIN to support the operations of another GSTIN of the same company, this is typically treated as a supply of manpower/management service between distinct persons, valued and cross-charged under Rule 28, unless a specific exemption or a defensible employer-employee relationship structure applies to that particular arrangement. This is a fact-specific area that has generated litigation and differing interpretations, so it needs case-by-case review rather than a blanket assumption in either direction.
Does RCM or branch cross-charge affect our GST rate — are we affected by the September 2025 GST rate rationalisation?
The GST rate rationalisation effective September 2025 restructured the general goods/services rate slabs; RCM and branch cross-charge liability is computed at whatever rate applies to the underlying supply itself under the current rate schedule — it does not introduce a separate RCM-specific rate. In practice, this means the RCM tax rate on, say, GTA services or legal services, and the cross-charge rate on a transferred service, must simply be checked against the currently applicable rate for that category of supply, not assumed to remain at a pre-rationalisation rate.
What if the branch receiving a cross-charge makes only exempt supplies — can it still claim full ITC on the cross-charge invoice?
No, not automatically. If the receiving branch makes exempt supplies (or a mix of taxable and exempt supplies), the general input tax credit restriction and reversal rules under Section 17(2) and Rule 42/43 of the CGST Rules apply to the cross-charge invoice just as they would to any other inward supply — full credit is only available to the extent attributable to taxable supplies. This is also relevant to the Rule 28 valuation shortcut, since the 'invoice value = open market value' simplification specifically assumes full ITC eligibility at the recipient.
How does PNPC identify RCM transactions we might be missing, rather than just the ones we already flag ourselves?
We do not rely solely on your existing bookkeeping tags. We independently review the vendor master and purchase register against the current CBIC-notified RCM categories, cross-check GTA vendor declarations, verify director sitting-fee treatment against Board minutes, and separately review any foreign-currency payments for import-of-service exposure. This independent line-by-line review is precisely how we typically surface at least one previously unflagged RCM category in a first engagement.
Is there a minimum business size below which RCM and branch compliance can be safely ignored?
No safe minimum exists in law — RCM liability under Section 9(3) applies based on the nature of the transaction (e.g., paying an advocate, hiring a GTA), not on the size of the paying business, and the distinct-person rule for branch cross-charge applies the moment a business holds more than one GSTIN, regardless of revenue scale. Smaller businesses often assume, incorrectly, that this compliance area is only relevant to large corporates — the exposure exists proportionately at any size, though the practical materiality of the amounts involved obviously scales with transaction volume.
How often should our RCM and branch cross-charge position be reviewed?
We recommend a monthly review aligned to the GSTR-3B filing cycle for active multi-branch or RCM-heavy businesses, with a deeper quarterly reconciliation against GSTR-2B and a full annual reconciliation ahead of GSTR-9/9C filing. Businesses with lower RCM/branch transaction volume may manage with a quarterly review, but the annual reconciliation before GSTR-9/9C should never be skipped, since this is where accumulated small mismatches typically surface.
What penalty exposure do we face if the department finds an unrecorded branch cross-charge during an audit?
Where the omission is treated as a bona fide error, the department can raise a demand under Section 73 with interest at 18% per annum and a penalty capped at 10% of the tax amount (or a smaller specified minimum), payable if settled within the prescribed window. Where the department alleges willful suppression or intent to evade — more likely if the same gap recurs across several periods without correction — Section 74 applies, carrying interest and a penalty of up to 100% of the tax amount. The specific classification depends heavily on the facts and how promptly the business corrects course once the gap is identified.
Can we recover GST paid under RCM if we later realise the supply was actually exempt or outside GST's scope?
If GST was paid under RCM on a transaction that, on closer review, was not actually taxable (for example, it fell under an exemption notification), the excess tax paid can generally be claimed as a refund under Section 54 of the CGST Act, subject to the applicable limitation period and the unjust-enrichment test. This is a fact-specific claim that requires a clear documentary basis establishing the exemption and should be pursued with proper professional support rather than a simple return adjustment.
Do e-way bill requirements apply to inter-branch stock transfers the same way they apply to third-party sales?
Yes. An e-way bill is required for the movement of goods above the prescribed value threshold (currently ₹50,000 in most states, with some state-specific variations) regardless of whether the movement is a sale to a third party or a stock transfer between two GSTINs of the same company. The e-way bill should be generated with reference to the tax invoice raised for the cross-charge — not merely a delivery challan — to keep the documentation trail consistent.
What if our branches are in different states with different local compliance requirements — does that change RCM treatment?
RCM under the CGST/IGST Act is a central-law mechanism and applies uniformly across India in terms of which categories are notified and how the tax is computed — GST itself is a national law, so RCM rules do not vary by state. However, whether a transaction between two branches attracts CGST+SGST (intra-state supply, which does not typically arise between distinct persons in different states) or IGST depends on whether the transferring and receiving GSTINs are in the same state or different states — cross-state branch transfers attract IGST, not CGST+SGST.
How does RCM interact with the Composition Scheme?
A business registered under the Composition Scheme cannot claim input tax credit at all — including on RCM payments. However, Composition taxpayers are still liable to pay GST under RCM on notified inward supplies in the same manner as regular taxpayers; they simply cannot recover that RCM payment as ITC, since the entire premise of the Composition Scheme is a simplified, credit-ineligible tax payment on turnover. This makes RCM a pure cost (not a pass-through) for Composition taxpayers, which is a relevant factor when evaluating whether Composition remains the right scheme for a business with significant RCM-liable purchases.
What documentation should we retain to defend our RCM and branch cross-charge positions in a future audit?
At minimum: the self-invoices raised for every RCM transaction, evidence of cash payment of the RCM liability, the ITC claim trail in GSTR-3B, the cross-charge tax invoices raised between GSTINs with the Rule 28 valuation basis documented, the ISD invoices and GSTR-6 filings if applicable, Board resolutions or agreements underlying director-fee or sponsorship arrangements, and GTA forward-charge declarations where relevant. We recommend retaining this documentation for at least the statutory limitation period applicable to GST demand proceedings, which can extend several years for Section 74 cases.
Our head office pays for a single group insurance policy covering employees across all our branches. How should the GST credit on this be handled?
This is a textbook ISD scenario — a single invoice for a service benefiting employees across multiple GSTINs. Where the mandatory-ISD conditions apply to your structure, the head office should hold ISD registration and distribute the eligible credit to each branch GSTIN in proportion to that branch's turnover under the Rule 39 formula, via a monthly ISD invoice and GSTR-6 filing, rather than claiming the full credit centrally or informally allocating it via a cross-charge invoice.
What is the cost of engaging PNPC for RCM and branch-transfer compliance, and how is it structured?
PNPC's fee for this engagement depends on the number of GSTINs involved, transaction volume, whether ISD registration needs to be newly obtained, and whether the engagement includes a historical clean-up exercise in addition to the ongoing monthly process. We provide a written scope and fixed-fee proposal after the initial exposure-mapping review, so you know the full cost before committing to the engagement — there is no open-ended hourly billing for this service.
Why should we engage a CA firm for this rather than manage RCM and branch compliance with our in-house accounting team?
In-house accounting teams are typically strong on day-to-day bookkeeping but are not always current on the specific, frequently-amended list of RCM-notified categories, the post-2025 mandatory ISD rules, or the Rule 28/39 valuation mechanics that this area requires. The compounding risk of RCM and branch cross-charge is that errors are usually silent for years — no vendor chases you for unpaid RCM tax, and no immediate cash-flow signal flags a missing cross-charge invoice — until a departmental audit surfaces several years of accumulated exposure at once. A periodic independent CA review is specifically designed to catch what an internal team, working from the same assumptions year after year, is structurally unlikely to catch on its own.
What does the PNPC RCM & Branch Transfer Compliance package include?
Full RCM exposure mapping against your vendor register and current CBIC notifications; self-invoicing process design and template setup; branch/GSTIN cross-charge framework with Rule 28 valuation methodology; ISD registration assessment and application where applicable; monthly RCM liability and ITC reconciliation against GSTR-3B; branch cross-charge invoice review and GSTR-1/GSTR-2B reconciliation; GSTR-6 filing where ISD registration applies; annual reconciliation ahead of GSTR-9/9C; and departmental query or audit support if a notice is received during the engagement period.
We are planning to open our first branch in another state next quarter. When should we start this compliance process?
Before the first inter-branch transaction occurs, ideally alongside the new GSTIN registration itself. Designing the cross-charge and ISD framework before the first stock transfer or shared-service arrangement takes place is materially simpler and cheaper than retrofitting correct treatment onto several months of already-completed, incorrectly-documented transactions.
Does RCM apply to services received from a Special Economic Zone (SEZ) unit or an SEZ developer?
Supplies to and from SEZ units carry their own distinct GST treatment (typically zero-rated for supplies to an SEZ unit/developer for authorised operations), which is a separate framework from the RCM rules discussed here. Where a domestic business outside the SEZ receives a notified RCM-category service from a supplier that happens to be located in an SEZ, the RCM mechanics generally still apply based on the nature of the service, but the interaction with SEZ zero-rating provisions needs a specific, fact-based review rather than a generic answer.
Is there a way to avoid RCM liability by restructuring how we engage advocates or GTAs?
RCM applies based on the substance of the service received and the category of supplier, not on how a contract is labelled — attempting to restructure engagements purely to avoid RCM (rather than for a genuine commercial reason) carries real risk of being recharacterised by the department, along with the underlying tax, interest, and potential penalty. The more productive approach is accurate identification, timely self-invoicing, and full, eligible ITC recovery — which, for a business with genuine input tax credit eligibility, makes RCM cash-flow-neutral over the return cycle rather than a real cost.
How does PNPC's presence in both India and the UAE help with cross-border service imports that trigger RCM?
For clients receiving services from UAE-based group entities or vendors — consulting, shared services, licensing, or management fees — our Dubai office can confirm the UAE-side invoicing and VAT treatment while our India teams confirm the correct Indian RCM self-invoicing and ITC treatment on the same transaction, so both sides of a single intercompany or vendor arrangement are handled coherently under one engagement rather than being reviewed in isolation by two unconnected advisors.
PNPC Global vs typical alternatives for RCM & branch-transfer compliance
| Factor | PNPC Global | Generic GST filing portal/vendor | In-house accounting team alone |
|---|---|---|---|
| RCM category identification | Independent line-by-line review against current CBIC notifications, refreshed on every rate/rule change | Relies on client-provided classification, rarely reviewed independently | Applies the same historical classification year after year, often missing recent notification changes |
| Branch cross-charge valuation | Rule 28 methodology applied with recipient ITC-eligibility check for the invoice-value-as-OMV shortcut | Usually not addressed at all — inter-branch movement often handled with only a delivery challan | Ad hoc, often based on an outdated internal template with no valuation basis documented |
| ISD registration & Rule 39 distribution | Mandatory-ISD determination and full registration + GSTR-6 filing support | Rarely proactively advised — most portals do not address ISD at all | Frequently unaware ISD became mandatory for their structure post-1 April 2025 |
| Historical exposure clean-up | Structured voluntary-disclosure approach to minimise penalty exposure before a department notice arrives | Not offered — portals handle only current-period filing, not historical review | Typically only discovered when a departmental notice forces the issue |
| Cross-border / UAE coordination | Single engagement covering both India RCM treatment and UAE-side documentation via our Dubai office | No cross-border capability | Requires engaging a separate advisor for the UAE side, with coordination gaps |
| Ongoing monthly reconciliation | RCM liability vs ITC claim, and cross-charge invoice vs GSTR-2B, reconciled every return cycle | Return filing only — reconciliation against GSTR-2B is the client's own responsibility | Time-permitting, often deprioritised against day-to-day bookkeeping demands |
| Departmental audit support | Full representation and reply drafting included in the retainer scope | Not offered — client must separately engage an advisor if a notice arrives | Internal team typically lacks the specific GST litigation/representation experience needed |
This comparison reflects the general pattern PNPC observes across client engagements and is not a claim about any specific named competitor. Every business's actual risk and cost profile should be assessed on its own facts.
