GST · GST Return Filing & Compliance
Specialised Returns (GSTR-5 NRTP, GSTR-5A OIDAR, GSTR-6 ISD, GSTR-7 TDS, GSTR-8 TCS)
GSTR-5, GSTR-5A, GSTR-6, GSTR-7, and GSTR-8 are not variants of the standard GSTR-1/GSTR-3B cycle — they are separate statutory return regimes built for five distinct categories of GST registrant: Non-Resident Taxable Persons (NRTP), Online Information and Database Access or Retrieval (OIDAR) service providers, Input Service Distributors (ISD), TDS deductors under Section 51, and e-commerce operators collecting TCS under Section 52.

GSTR-5, GSTR-5A, GSTR-6, GSTR-7, and GSTR-8 are not variants of the standard GSTR-1/GSTR-3B cycle — they are separate statutory return regimes built for five distinct categories of GST registrant: Non-Resident Taxable Persons (NRTP), Online Information and Database Access or Retrieval (OIDAR) service providers, Input Service Distributors (ISD), TDS deductors under Section 51, and e-commerce operators collecting TCS under Section 52. Each carries its own due date, its own form structure, and its own penalty exposure — and each is filed far less often by most CA firms than mainstream monthly returns, which is exactly why errors are common. At PNPC Global, we have managed specialised GST return portfolios for businesses and government-linked entities across Chennai, Bangalore, Hyderabad, and Dubai since 2017. We do not treat these as edge-case filings. We track the NRTP registration validity window before it lapses, reconcile ISD input credit distribution against every recipient GSTIN, verify TDS/TCS certificates the deductee actually needs, and file OIDAR returns for offshore digital service providers who often have no other India compliance touchpoint. Specialised returns require specialised attention — that is what we bring.
What it costs
No hidden charges. The exact figure is set in your engagement letter.
Under the CGST Act 2017 and the CGST Rules 2017, certain categories of GST registrants file returns outside the standard GSTR-1/GSTR-3B monthly cycle because their business model, registration type, or statutory role does not fit the regular taxpayer framework. GSTR-5 is filed by a Non-Resident Taxable Person (NRTP) — a person who occasionally undertakes taxable transactions in India without a fixed place of business here, such as a foreign exhibitor at a trade fair or a short-term service provider. GSTR-5A is filed by Online Information and Database Access or Retrieval (OIDAR) service providers — offshore entities supplying digital services (streaming, e-books, cloud software, online gaming, and similar) to non-taxable recipients in India, registered under the simplified OIDAR registration scheme rather than standard GST registration. GSTR-6 is filed by an Input Service Distributor (ISD) — an office of a business that receives invoices for input services on behalf of its branches and distributes the input tax credit (ITC) proportionately to those branches by GSTIN. GSTR-7 is filed by any deductor required to deduct TDS under Section 51 of the CGST Act — principally government departments, local authorities, and specified categories of persons making payments above the threshold to a GST-registered supplier. GSTR-8 is filed by an e-commerce operator required to collect TCS under Section 52 of the CGST Act on the net value of taxable supplies made through its platform by other sellers.
What unites these five returns is that each registrant type exists to serve a specific structural gap in the GST framework rather than to report the registrant's own primary sales activity in the way a regular dealer's GSTR-1 does. An NRTP's GSTR-5 reports transactions during a registration validity period that is itself time-bound and must be renewed or allowed to lapse deliberately. An OIDAR supplier's GSTR-5A exists because a foreign digital-service provider with no Indian establishment would otherwise fall outside India's GST net on B2C digital supplies — the return closes that gap by taxing the supply at the point of consumption. An ISD's GSTR-6 exists purely to allocate credit that has already been paid — the ISD itself typically has no output tax liability of its own from this activity; it is a credit-distribution mechanism, not a sales-reporting one. GSTR-7 and GSTR-8 exist because the deductor/collector is not the taxpayer whose liability is being reported — they are withholding agents reporting tax collected on behalf of a third party (the supplier or seller), similar in concept to TDS under the Income Tax Act but operating within the GST framework under Sections 51 and 52 of the CGST Act.
Each of these returns carries statutory certificate obligations that flow to a third party. A TDS deductor under GSTR-7 must issue a TDS certificate in Form GSTR-7A to the deductee, generated automatically once GSTR-7 is filed and the deductee can view the credited amount in their GSTR-2B/electronic cash ledger. Similarly, TCS collected and reported in GSTR-8 reflects in the seller's electronic cash ledger as a claimable credit against their own output tax liability. This means that errors, omissions, or late filing by the deductor/collector under these returns do not just create the filer's own compliance exposure — they delay or block a third party's legitimate credit, which is a recurring source of business disputes between principals and their withholding counterparties.
Due dates and thresholds for all five returns are fixed by CGST Rules and periodically clarified by CBIC notifications and circulars — they are not negotiable dates a business can push out. NRTP registration itself is valid only for the period specified in the registration application or 90 days from the effective date of registration, whichever is earlier, and is extendable only once for a further period as permitted by the proper officer, with advance tax deposit required upfront based on estimated liability. OIDAR registration for offshore suppliers follows a simplified scheme (Form GST REG-10) precisely because these entities may have no fixed establishment or authorised signatory physically present in India. ISD registration is a distinct registration category under Section 24, mandatory for any office that intends to distribute common input service credit — a business cannot distribute ITC without holding this specific registration. Because each of these five return types is filed by a comparatively small, specialised population of registrants, generalist accounting teams and standard GST-filing software workflows frequently mishandle them — which is precisely the gap PNPC's specialised-returns practice is built to close.
When your business needs specialised GST return filing
You are a foreign or out-of-state business undertaking occasional taxable supplies in India without a fixed place of business — trade fairs, exhibitions, short-term project work, or event-based services — requiring NRTP registration and GSTR-5
You are an offshore entity supplying digital content, streaming, cloud software, e-books, online gaming, or similar OIDAR services to non-business consumers in India, requiring OIDAR registration and GSTR-5A
Your business has a head office or central procurement office that receives common input service invoices (audit fees, software licences, group insurance, consultancy) on behalf of multiple branch GSTINs and needs to distribute that credit under an ISD registration and GSTR-6
You are a government department, PSU, local authority, or a specified body notified as a TDS deductor under Section 51, making payments above the threshold to GST-registered suppliers under a taxable contract
You operate an e-commerce platform through which other sellers supply goods or services and collect payment on their behalf, making you liable to collect TCS under Section 52 and file GSTR-8
You need to correctly issue GSTR-7A TDS certificates or ensure TCS collected under GSTR-8 correctly reflects in your sellers' electronic cash ledger, avoiding vendor disputes over blocked credit
When the standard GST return cycle applies instead
You are a regular India-resident taxpayer supplying goods or services domestically with a fixed place of business — you file GSTR-1 and GSTR-3B (or the QRMP quarterly-with-monthly-payment variant), not any of the specialised returns
You have opted for the Composition Scheme under Section 10 — you file CMP-08 quarterly and GSTR-4 annually instead of any of GSTR-5/5A/6/7/8
Your business receives input services directly against its own GSTIN without any need to distribute credit to other branches — you claim ITC directly in your own GSTR-3B and do not need ISD registration
Your organisation makes payments to GST-registered suppliers but is not specifically notified as a Section 51 TDS deductor — most private-sector businesses are not covered and should not attempt to deduct GST TDS without confirming applicability
You run an e-commerce presence but only sell your own goods/services (not facilitating third-party sellers) — you are not an 'e-commerce operator' for TCS purposes and file standard GSTR-1/GSTR-3B instead
Your annual return and reconciliation needs (GSTR-9/9C) are the concern — that is covered under PNPC's separate GST Annual Return service, not this specialised-returns engagement
GSTR-5 vs GSTR-5A vs GSTR-6 vs GSTR-7 vs GSTR-8 — who files what, and why
| Feature | GSTR-5 (NRTP) | GSTR-5A (OIDAR) | GSTR-6 (ISD) | GSTR-7 (TDS) | GSTR-8 (TCS) |
|---|---|---|---|---|---|
| Filed by | Non-Resident Taxable Person | Offshore OIDAR service provider | Input Service Distributor | Notified TDS deductor (Sec 51) | E-commerce operator (Sec 52) |
| Underlying registration | Special NRTP registration (Form GST REG-09) | Simplified OIDAR registration (Form GST REG-10) | ISD registration under Sec 24 | Standard/TAN-linked GSTIN as deductor | Standard GSTIN as e-commerce operator |
| What it reports | Outward/inward supplies and tax during the NRTP registration validity period | Value of OIDAR digital supplies made to non-taxable recipients in India | Input service credit received and its distribution across recipient GSTINs | Tax deducted at source on payments to registered suppliers | Net value of supplies made through the platform and TCS collected |
| Filing frequency | Monthly (or for the registration validity period, if shorter) | Monthly | Monthly | Monthly | Monthly |
| Standard due date | 20th of the following month (or within 7 days of registration validity expiry, if earlier) | 20th of the following month | 13th of the following month | 10th of the following month | 10th of the following month |
| Own output tax liability? | Yes — pays tax on its own India transactions | Yes — pays tax on OIDAR supplies made | No — pure credit pass-through, no output tax of its own on this activity | No — deducts and deposits tax on another party's behalf | No — collects and deposits tax on another party's behalf |
| Third-party document generated | None specific — supplier's own return | None specific — supplier's own return | ITC auto-populates in recipient GSTINs' GSTR-2B/2A | GSTR-7A TDS certificate for the deductee | TCS credit reflects in seller's electronic cash ledger |
| Advance tax deposit required | Yes — estimated liability deposited before registration is granted | Not applicable in the same way — no advance deposit regime | Not applicable — no tax payment, only credit distribution | Not applicable — deducted only when payment is made | Not applicable — collected only when consideration is settled |
| Typical filer profile | Foreign exhibitor, short-term contractor, event-based supplier with no fixed India establishment | Streaming platforms, SaaS providers, e-book/gaming platforms based outside India serving Indian consumers | Corporate head office, shared-services centre, group procurement office | Government departments, PSUs, local authorities, specified notified persons | Marketplace and aggregator platforms (not sellers of their own inventory) |
| Registration cap/limit | Valid for period applied for, max 90 days, extendable once | No fixed validity cap tied to a business event | No validity cap — ongoing registration | No validity cap — ongoing registration | No validity cap — ongoing registration |
| ITC available to filer | Yes, on inputs/input services used for taxable supply in India, subject to conditions | Not applicable — supplier typically has no India-side purchases to claim against | Not applicable — ISD only distributes, does not claim for its own consumption | Not applicable — deductor is not availing ITC through this filing | Not applicable — operator is not availing ITC through this filing |
| Common compliance failure PNPC sees | Registration allowed to lapse mid-event; advance tax estimate significantly off actual | Return not filed at all — offshore providers often unaware of the obligation until a notice arrives | Credit distributed to the wrong GSTIN or in a wrongly apportioned ratio | GSTR-7A certificate never generated/shared, leaving deductee's credit disputed | TCS collected but GSTR-8 not reconciled against actual platform settlement data |
This table gives directional guidance only. Whether your business needs one, several, or none of these returns depends on your exact registration category, business model, and the specific notifications applicable to your sector. A consultation with a practising CA is the appropriate first step before assuming applicability either way.
| # | Stage & What PNPC Does | CA Advice Portals Never Give | Timeline |
|---|---|---|---|
| 1 | Applicability Assessment — Which of the five returns actually apply to you | Many businesses assume they need a specialised return when they do not, or miss one they genuinely do. We map your actual registration category (NRTP/OIDAR/ISD/TDS-notified/e-commerce operator) against the statutory definitions in Sections 24, 51, 52 and the OIDAR rules before recommending any filing regime — rather than defaulting to whatever a software template suggests. | Day 1–2 |
| 2 | Registration Verification or Fresh Registration — Confirming the correct registration category is in place | GSTR-5 cannot be filed without valid NRTP registration (Form GST REG-09); GSTR-5A requires OIDAR registration (Form GST REG-10); GSTR-6 requires ISD registration under Section 24. Filing a specialised return without the matching registration category active is not possible on the GST portal — the registration must precede the return. We verify or initiate the correct registration first. | Day 2–10 depending on registration type |
| 3 | NRTP Advance Tax Estimation (where applicable) — Estimating liability before registration is even granted | NRTP registration is conditional on an advance deposit of estimated tax liability for the registration period. Under-estimating creates a liability gap discovered only at GSTR-5 filing; over-estimating locks up working capital unnecessarily. We build a defensible estimate from your actual contracted India activity — not a generic guess. | Before registration is granted |
| 4 | OIDAR Applicability Review (where applicable) — Confirming your digital supply actually meets the OIDAR definition | Not every digital service is OIDAR — the definition under the IGST Act requires supply that is essentially automated, delivered over the internet, and involves minimal human intervention. Getting this wrong either creates unnecessary compliance or, worse, leaves a genuine OIDAR liability unaddressed until a notice arrives from DGGI or the jurisdictional officer. | Day 3–7 |
| 5 | ISD Credit Mapping (where applicable) — Building the recipient-GSTIN distribution logic | Credit must be distributed to recipient GSTINs in the same proportion as their turnover in the relevant period (or as prescribed for specific input service categories), not arbitrarily or equally. We build and maintain the ISD distribution working — turnover ratios, invoice-level mapping, and recipient GSTIN validation — before the first GSTR-6 is filed. | Ongoing, refreshed each period |
| 6 | TDS/TCS Threshold & Notification Check (where applicable) — Confirming you are actually covered | Section 51 TDS applies only to specifically notified categories of deductors (government departments, PSUs, and other notified persons) on contracts above the prescribed value threshold. Section 52 TCS applies only to entities that meet the statutory definition of an 'e-commerce operator' facilitating supply by other persons. We confirm applicability against the current notifications before any deduction/collection begins — over-deducting creates disputes with suppliers; under-deducting creates the deductor's own exposure. | Day 2–5 |
| 7 | Monthly Data Preparation — Building the return dataset from source records | GSTR-5 needs outward/inward supply details for the NRTP period; GSTR-5A needs state-wise OIDAR supply value; GSTR-6 needs input service invoice-level data with recipient allocation; GSTR-7 needs deductee-wise payment and deduction detail; GSTR-8 needs seller-wise, transaction-wise supply and TCS detail. Each has a different data shape — we build the source-data template specific to each return type rather than forcing all five into one generic export. | Monthly, ahead of each due date |
| 8 | Return Filing & Portal Submission — GSTN portal filing with DSC/EVC as applicable | We file directly on the GST portal, applying digital signature or EVC as required for the entity type, and retain acknowledgement and ARN records for audit trail purposes. | By the statutory due date each month (10th/13th/20th depending on return) |
| 9 | GSTR-7A Certificate Issuance (for TDS deductors) — Generating and sharing the deductee certificate | GSTR-7A is auto-generated on the portal once GSTR-7 is filed and payment is made, but it must be downloaded and actively shared with the deductee — it does not push automatically to their inbox. We track this as a distinct post-filing step so deductees are not left chasing their own credit. | Immediately after GSTR-7 filing |
| 10 | TCS Reconciliation (for e-commerce operators) — Matching GSTR-8 data to seller settlement records | TCS reported in GSTR-8 must tie back to actual platform settlement records seller-by-seller. Mismatches surface as seller disputes when their GSTR-2B credit does not match what they expected. We reconcile before filing, not after a seller complaint arrives. | Before each GSTR-8 filing |
| 11 | Notice & Query Handling — Responding to department queries on specialised filings | Because these returns are filed by a smaller population, department scrutiny (ASMT-10, DRC-01A) on specialised filers tends to focus on registration validity, credit distribution ratios, and TDS/TCS threshold applicability. We handle these responses directly, drawing on the working papers built during monthly filing rather than reconstructing history under notice pressure. | As needed |
| 12 | NRTP Registration Renewal or Closure (where applicable) — Managing the registration lifecycle | NRTP registration is time-bound and does not auto-renew. We track the validity window and manage either a formal extension application (permitted once, for a further period as allowed by the proper officer) or an orderly closure with final GSTR-5 filing and any refund of excess advance tax deposited. | Tracked against each registration's specific validity date |
Because these five returns each serve a distinct, comparatively small population of registrants, realistic engagement timelines vary widely by return type — an NRTP engagement may run only a few weeks for a single event, while an ISD or e-commerce operator engagement is an ongoing monthly retainer. PNPC scopes each engagement to the actual registration category and filing cadence involved.

| Phase | Triggered By | PNPC CA Guidance | Risk If Ignored |
|---|---|---|---|
| Applicability Determination | New India activity, digital supply model, group credit structure, or notified TDS/TCS role identified | Confirm which of the five specialised returns genuinely applies based on registration category and business model — not assumption. Initiate the correct registration (NRTP/OIDAR/ISD) if not already held. | Filing the wrong return or none at all; operating under an incorrect registration category creates downstream filing rejections and potential penalty exposure. |
| Registration Setup | NRTP/OIDAR/ISD registration application | Prepare and file the specific registration form (REG-09/REG-10/ISD registration under Section 24), including NRTP advance tax estimation where applicable. | NRTP registration denied or delayed if advance tax estimate is inadequate or documentation is incomplete; OIDAR non-registration discovered later via department data-matching with payment gateways. |
| Monthly Filing Cycle | Each return period (monthly for all five returns) | Prepare period-specific data (outward/inward supply, OIDAR supply value, ISD credit distribution, TDS/TCS ledger), file by the statutory due date (10th/13th/20th depending on return), and issue GSTR-7A certificates or confirm TCS credit reflection where applicable. | Late fee and interest exposure; blocked or delayed third-party credit (deductee's TDS credit, seller's TCS credit, recipient GSTIN's ISD credit) creating vendor/franchisee disputes. |
| NRTP Validity Tracking | Approaching the end of the registration validity window (up to 90 days, extendable once) | Track the specific validity end date; decide and execute either a formal extension application before expiry or an orderly final GSTR-5 filing and registration closure. | Registration lapses mid-activity, leaving ongoing India transactions unregistered — triggering GST demand, interest, and penalty exposure for operating without valid registration. |
| Credit/Certificate Reconciliation | Recipient GSTIN or deductee/seller queries their credit position | Proactively reconcile ISD distribution, GSTR-7A certificate issuance, and TCS credit reflection against recipient/deductee/seller expectations before disputes escalate. | Recipient businesses lose confidence in the filer's compliance discipline; disputes over blocked credit can affect ongoing commercial relationships (franchisee, vendor, or group-company terms). |
| Department Scrutiny | ASMT-10 notice, DRC-01A intimation, or data-matching query on a specialised return | Respond using the working papers maintained through the monthly filing cycle — registration validity proof, credit distribution basis, TDS/TCS threshold applicability — rather than reconstructing records under time pressure. | Inadequate or delayed response can escalate to formal demand proceedings under Section 73/74 of the CGST Act, with the associated interest and penalty exposure. |
| Annual Review & Renewal Decisions | Financial year-end or change in business model (e.g., ISD office consolidated, e-commerce operator status changes) | Reassess whether the specialised registration and return obligation still applies — business model changes (e.g., OIDAR supplier appointing an India subsidiary, ISD office restructuring) can shift the applicable return regime entirely. | Continuing to file a return that no longer reflects the correct registration category, or failing to register for a newly-triggered obligation as the business model evolves. |
What is a Non-Resident Taxable Person (NRTP) under GST and who needs this registration?
An NRTP is any person who occasionally undertakes transactions involving supply of goods or services, or both, in India, but who has no fixed place of business or residence in India. This typically covers foreign exhibitors at trade fairs, short-term event organisers, foreign contractors executing a specific India-based project, and similar occasional suppliers. NRTP registration is obtained on Form GST REG-09 and is distinct from regular GST registration — it does not require a PAN in the same way (a tax identification number from the home country can substitute in specified circumstances) but does require an authorised signatory who is a resident of India with a valid PAN.
How long is NRTP registration valid, and can it be extended?
NRTP registration is valid for the period specified in the registration application, or 90 days from the effective date of registration, whichever is earlier. It can be extended once, for a further period as permitted by the proper officer, by filing Form GST REG-11 before the expiry of the original validity period, along with an additional advance tax deposit corresponding to the extended period's estimated liability.
Why does NRTP registration require an advance tax deposit before it is even granted?
Because an NRTP, by definition, has no fixed establishment or ongoing presence in India, the department has limited ability to pursue collection after the fact if the NRTP's India activity concludes and the entity departs. The advance deposit — an amount equivalent to the estimated tax liability for the registration period — is required upfront as a safeguard, and is adjusted against the actual liability reported in GSTR-5, with any excess refundable on closure.
What does GSTR-5 actually report, and what is the due date?
GSTR-5 reports outward supplies made and inward supplies (including imports) received by the NRTP during the registration validity period, along with the tax payable and paid. It is filed monthly, by the 20th of the month following the tax period, or within 7 days after the last day of the registration validity period, whichever is earlier.
What is OIDAR and which businesses fall under it?
Online Information and Database Access or Retrieval (OIDAR) services are digital services delivered over the internet or an electronic network, where the supply is essentially automated and involves minimal human intervention, and which would be impossible to provide without information technology. Examples include streaming media, cloud-based software, downloadable e-books and digital content, online gaming, web-hosting, and automated online advisory services. The concept is defined under the IGST Act and its associated rules.
Does an offshore OIDAR supplier need to register for GST in India even without any physical presence?
Yes, if the OIDAR supplier makes supplies to non-taxable recipients (typically individual consumers, i.e., B2C) located in India. A simplified registration scheme exists precisely because these suppliers have no fixed establishment in India — registration is obtained on Form GST REG-10, and the supplier can appoint a person in India for compliance purposes, though this is not always mandatory depending on the specific facts. If the OIDAR supply is instead made to a GST-registered business (B2B) in India, the recipient business typically discharges GST under reverse charge, and the offshore supplier does not need to register for that specific B2B transaction.
How does GSTR-5A determine which supplies are 'made in India' for a digital service with no physical delivery?
Because OIDAR services have no physical delivery point, the place of supply and recipient location are determined using proxy indicators specified in the rules — such as the recipient's billing address, the internet protocol (IP) address of the device used, the recipient's bank account details used for payment, the country code of the SIM card used, or the location of the recipient's fixed landline through which the service is received. Two or more non-contradictory indicators are typically used together to establish the recipient's location in India.
What is an Input Service Distributor (ISD) and why would a business need one?
An Input Service Distributor is an office of a business — typically the head office, corporate office, or a shared-services centre — that receives tax invoices for input services procured centrally (audit fees, group insurance, software licences, legal and consultancy fees, and similar) on behalf of its branches or units registered under different GSTINs, and distributes the input tax credit on those invoices proportionately to the recipient units. ISD registration is a distinct registration category under Section 24 of the CGST Act, mandatory for any office intending to perform this distribution function — a business cannot distribute common input service credit to its branch GSTINs without first holding ISD registration.
How is ISD credit distributed among recipient units — is it always an equal split?
No. Credit is distributed to recipient units in the same ratio as the turnover of each recipient unit to the aggregate turnover of all recipient units during the relevant period (the immediately preceding financial year, or the last quarter for which turnover figures are available, as prescribed under the CGST Rules), not on an equal basis and not on the ISD's own discretion. Certain categories of input service credit that relate exclusively to one particular recipient unit must be distributed only to that unit, not pro-rated across all units.
What is the due date for GSTR-6 and what happens if it is filed late?
GSTR-6 is due on the 13th of the month following the tax period. Unlike GSTR-1/GSTR-3B, GSTR-6 has no concept of a 'nil return' waiver in the same way — if any input service invoice has been received during the period, distribution and filing are required. Late filing attracts late fee under the CGST Act and, more materially, delays the recipient GSTINs' ability to claim the distributed credit in their own returns for that period.
Can an ISD claim GST refunds or use the distributed credit for its own output tax liability?
No. An ISD, in that specific registration capacity, does not have its own output tax liability arising from the distribution activity and does not use the credit itself — it exists solely to receive and pass on eligible input service credit to the recipient units that are actually liable to pay output tax. Ineligible or blocked credit under Section 17(5) must be excluded from distribution altogether, not distributed and then reversed by the recipient.
Who is required to deduct TDS under GST, and is it the same as Income Tax TDS?
GST TDS under Section 51 of the CGST Act is a separate mechanism from Income Tax TDS under the Income-tax Act — they operate under different statutes, at different rates, on different tax bases, with different filing forms. Section 51 TDS applies only to specifically notified categories of deductors — government departments and establishments, local authorities, governmental agencies, and other persons specifically notified by the government — who are required to deduct tax at the prescribed rate when making payment to a GST-registered supplier under a taxable contract exceeding the prescribed threshold value.
What is the rate of GST TDS and on what value is it calculated?
GST TDS is deducted at 1% under CGST and 1% under SGST (for intra-state supply) or 2% under IGST (for inter-state supply), calculated on the taxable value of the supply under the contract — excluding the GST component itself. It applies only where the total value of the supply under an individual contract exceeds the prescribed threshold.
What is GSTR-7A and why does it matter if we deduct GST TDS?
GSTR-7A is the TDS certificate that is auto-generated on the GST portal once the deductor files GSTR-7 and the corresponding tax is deposited. It is made available to both the deductor and the deductee for download, reflecting the deduction details for that period. The deductee needs this certificate as documentary evidence of the TDS credited to their electronic cash ledger, which they can then use to offset their own output tax liability.
What is the due date for GSTR-7, and what is the penalty for late filing?
GSTR-7 is due on the 10th of the month following the tax period. Late filing attracts late fee under the CGST Act along with interest on any TDS amount not deposited by the due date. Because GSTR-7 filing directly gates the deductee's ability to claim their TDS credit, a late filing has knock-on consequences for a third party's compliance position, not just the deductor's own exposure.
Who qualifies as an 'e-commerce operator' liable to collect TCS under Section 52?
An e-commerce operator, for TCS purposes, is a person who owns, operates, or manages a digital or electronic facility or platform for electronic commerce through which other suppliers make supplies of goods or services, and who collects the consideration for those supplies on behalf of the actual supplier (or is otherwise responsible for collecting the payment). A business that sells only its own goods/services through its own website, without facilitating supplies by other independent sellers, does not fall within this definition and does not have a TCS obligation.
What rate of TCS applies under GSTR-8, and on what value?
TCS is collected at 0.5% CGST plus 0.5% SGST (for intra-state supply) or 1% IGST (for inter-state supply), calculated on the net value of taxable supplies made through the operator's platform — meaning the aggregate value of taxable supplies, less the aggregate value of supplies returned, for the relevant period.
How does a seller on an e-commerce platform actually benefit from the TCS collected under GSTR-8?
TCS collected and deposited by the operator reflects in the seller's electronic cash ledger once the operator's GSTR-8 is filed and matched against the seller's own claim in their GSTR-3B. The seller can then use this credited amount to offset their own output GST liability, effectively treating it as tax already paid on their behalf.
What is the due date for GSTR-8, and does a nil return need to be filed if no supplies were facilitated?
GSTR-8 is due on the 10th of the month following the tax period. If the operator facilitated no supplies and collected no TCS during a period, a nil return generally still needs to be filed to maintain continuity of compliance and avoid the appearance of a filing default — the specific nil-filing mechanics should be confirmed for the applicable period against the current GST portal process.
Can the specialised returns be filed on a quarterly basis, similar to QRMP for regular taxpayers?
No. GSTR-5, GSTR-5A, GSTR-6, GSTR-7, and GSTR-8 are all monthly returns under the current framework — none of them are eligible for the QRMP (Quarterly Return Monthly Payment) scheme, which is specific to regular taxpayers filing GSTR-1 and GSTR-3B below the prescribed turnover threshold.
Do specialised return filers still need to file the annual return, GSTR-9?
GSTR-9 annual return applicability depends on the registration category and turnover, and is assessed separately from the monthly specialised return obligation. NRTP, OIDAR (via GSTR-5A), and ISD registrants are generally outside the standard GSTR-9 framework given the nature of their registration, while an e-commerce operator's GSTR-9 applicability follows the standard turnover-based rules applicable to any registered person. This is assessed case-by-case and is outside the scope of this specialised-returns engagement — PNPC's GST Annual Return service covers GSTR-9/9C separately.
What happens if an NRTP fails to file GSTR-5 or lets registration lapse mid-activity?
Continuing to undertake taxable supplies in India after NRTP registration has lapsed, without a valid extension, exposes the business to demand for tax, interest, and penalty for operating without valid registration — the same exposure any unregistered taxable person faces under Section 122 and related provisions of the CGST Act. Failure to file GSTR-5 within the validity period also puts the advance tax deposit refund at risk pending resolution of the outstanding return.
What are the late fee and interest consequences for GSTR-6, GSTR-7, and GSTR-8?
Late filing of these returns attracts late fee under the CGST Act (subject to the applicable per-day rate and cap prescribed for each return category) along with interest on any tax/TDS/TCS amount not deposited by the due date. Interest for delayed payment of GST-related dues generally runs at 18% per annum from the due date to the date of actual payment, consistent with the interest rate applicable to delayed GST payments generally.
Can a single business be liable for more than one of these five specialised returns at the same time?
Yes. It is entirely possible, and not uncommon, for a large group to have a head office that files GSTR-6 as an ISD, while a separate marketplace subsidiary of the same group files GSTR-8 as an e-commerce operator, and a government-facing division is separately notified as a Section 51 TDS deductor filing GSTR-7. Each obligation attaches to the specific registration/entity/role, not to the group as a whole.
How does PNPC handle the fact that these returns are filed by a much smaller population than GSTR-1/GSTR-3B?
Because specialised returns are filed less frequently across the market as a whole, many accounting teams and even some GST software workflows are not built around their specific data requirements. PNPC maintains dedicated working templates for each of the five return types — separate from our standard GSTR-1/GSTR-3B process — built around the specific data shape each return requires (NRTP period-based supply data, OIDAR recipient-location evidence, ISD turnover-ratio distribution, TDS/TCS deductee/seller-wise ledgers).
Does PNPC handle the underlying registration (NRTP/OIDAR/ISD) as well as the ongoing return filing?
Yes. PNPC handles the full lifecycle — assessing applicability, preparing and filing the initial registration application (Form GST REG-09 for NRTP, Form GST REG-10 for OIDAR, ISD registration under Section 24), the ongoing monthly return filing, and, where relevant, registration renewal, extension, or closure.
Can PNPC manage specialised GST returns for an offshore entity with no physical presence in India at all?
Yes. This is one of the more common scenarios in our OIDAR practice — an offshore digital service provider with no India office, no India-resident director, and no other India compliance touchpoint beyond this specific GST obligation. We manage the registration, monthly filing, and any department correspondence as the entity's sole point of India GST compliance contact.
How does PNPC support a UAE-based business that needs both India specialised GST compliance and UAE-side reporting?
PNPC operates from Chennai, Bangalore, Hyderabad, and Dubai. For a UAE-headquartered business with an India-facing digital service, an India NRTP event, or an India ISD/e-commerce structure, we coordinate the India-side GST specialised return work with our Dubai office's UAE VAT/Corporate Tax advisory, so the client deals with one firm across both jurisdictions rather than separate providers who do not share context.
What data does PNPC need on a recurring basis to manage an ongoing ISD or e-commerce operator filing retainer?
For an ISD retainer: monthly invoice-level data on input services received centrally, and current turnover figures for each recipient GSTIN. For an e-commerce operator retainer: monthly seller-wise, transaction-wise supply value and settlement data from the platform. We agree a specific data-export format and delivery schedule with each client at engagement start so that monthly filing does not depend on ad hoc, manually assembled data each time.
How does PNPC price a specialised GST return engagement?
Pricing depends on which of the five returns apply, the transaction volume involved, whether registration setup is also required, and whether the engagement is a one-off (typical for an NRTP event-based registration) or an ongoing monthly retainer (typical for ISD or e-commerce operator filings). PNPC agrees a specific, written fee structure for each engagement before work begins rather than applying a single generic price across very different filing profiles.
Why should a business use PNPC rather than attempting these specialised returns through general accounting software or an in-house team?
General GST-filing software is built primarily around the high-volume GSTR-1/GSTR-3B workflow. NRTP, OIDAR, ISD, TDS, and TCS filings each have distinct data structures, registration prerequisites, and third-party knock-on effects (deductee/recipient/seller credit) that a generalist workflow frequently does not surface clearly. PNPC's specialised-returns practice exists specifically because these five return types, taken together, are filed by a comparatively small, specialised population — and errors in this space tend to go unnoticed for longer precisely because they are less commonly reviewed.
What does PNPC's specialised GST return engagement typically include, end to end?
Applicability assessment across all five return types; registration verification or fresh registration (NRTP/OIDAR/ISD) where needed; NRTP advance tax estimation; OIDAR recipient-location determination methodology; ISD credit distribution working and monthly filing; TDS/TCS threshold confirmation, deduction/collection working, and monthly filing; GSTR-7A certificate tracking and TCS reconciliation; department notice and query response; and registration lifecycle management (NRTP renewal/closure).
If our business model changes mid-year — for example, an OIDAR supplier sets up an India subsidiary — does the specialised return obligation change?
Potentially, yes. If an offshore OIDAR supplier establishes a fixed place of business or an India subsidiary that takes over the supply relationship, the compliance framework can shift from the simplified OIDAR/GSTR-5A regime to standard GST registration and the regular GSTR-1/GSTR-3B cycle, depending on how the revised structure is set up. Similarly, if a group consolidates or splits its ISD office, the credit distribution structure needs to be reassessed.
PNPC Global vs generic GST-filing software/portals for specialised returns
| Aspect | Generic GST Filing Software/Portal | PNPC Global |
|---|---|---|
| Applicability assessment | Assumes user already knows which return applies | We assess NRTP/OIDAR/ISD/TDS/TCS applicability against the actual registration category and business model before recommending any filing |
| Registration handling | Typically return-filing only; registration is a separate, disconnected step | We handle registration (REG-09/REG-10/ISD under Section 24) and the ongoing return filing as one coordinated engagement |
| NRTP advance tax estimate | No advisory input — user supplies the figure | We build a defensible estimate from actual contracted India activity, avoiding both under- and over-estimation |
| OIDAR recipient-location evidence | Not addressed — assumes location is already determined | We build and document the multi-indicator evidence basis (billing address, IP, payment method, SIM country code) |
| ISD credit distribution logic | Generic templates, sometimes equal-split by default | We apply the prescribed turnover-ratio method and maintain the working papers behind every distribution |
| GSTR-7A / TCS third-party follow-through | Certificate generated on portal but not actively tracked or shared | We track and proactively share GSTR-7A certificates and reconcile TCS against seller settlement data |
| Department notice response | Not offered — user is on their own | We respond to ASMT-10/DRC-01A queries using the working papers built during monthly filing |
| NRTP registration lifecycle | No tracking of validity windows | We track validity end-dates and manage extension or closure proactively |
| Cross-border coordination | Not applicable | Dubai office coordinates India specialised GST filings with UAE VAT/CT compliance for cross-border clients |
| Engagement model | Self-service, per-filing transactional | Written scope and fee agreed upfront; ongoing retainer or event-based engagement as appropriate |
This comparison reflects typical differences between self-service filing tools and a CA-led specialised-returns practice. Actual software capabilities vary by provider.

Specialised GST returns are filed by a smaller population than GSTR-1/GSTR-3B — which is exactly why they get less scrutiny from generalist providers and more scrutiny from the department when something goes wrong. Talk to PNPC Global before your next GSTR-5, GSTR-5A, GSTR-6, GSTR-7, or GSTR-8 filing is due.
