Private Limited Company Registration — Post-Registration Compliance Guide
Incorporating a Private Limited Company in India is only the starting line — the real discipline begins the day the Certificate of Incorporation is issued, because the Companies Act, 2013 (as amended) and GST law both switch on a running clock of deadlines that don't pause for a new business finding its feet. Founders who treat post-registration compliance as an afterthought routinely discover, a year or two in, that late fees, frozen DINs, or a struck-off company status have quietly stacked up while they were focused on sales and product. This guide walks through the obligations that typically fall in the first three to twelve months — PAN/TAN activation, GST registration where applicable, statutory registers, annual ROC filings, and director KYC — organized in the rough order a founder or company secretary would actually encounter them. It also flags the penalties tied to each miss, so you can prioritize by consequence rather than by whichever notice arrived last. Where a fee, threshold, or form number could plausibly change with a future amendment, we've flagged it for verification rather than stating it as fixed.
Before you start
- Valid DIN/DSC (Class 3 Digital Signature Certificate) for all Directors
- PAN Card and TAN of the Company from SPICe+ processing
- Registered Office Address Proof (rent agreement/NOC and utility bill)
- Certificate of Incorporation and MOA/AOA copies on file
- Bank account opened in the company's name with initial capital infused
- First Board Meeting held within 30 days of incorporation
- Auditor appointed within 30 days of incorporation (Form ADT-1)
- Access to the MCA V3 portal with all directors' KYC completed
Step-by-step
Confirm PAN, TAN, and Bank Account Activation
SPICe+ (Form INC-32) issues PAN and TAN automatically alongside incorporation in most cases, but it's worth confirming both are active and reflected correctly with your bank before you start invoicing. Open a current account in the company's name and route the subscribed share capital into it — this becomes your paper trail for the Form INC-20A declaration.
- Cross-check the company's legal name and PAN spelling against the Certificate of Incorporation
- Retain the bank's capital-infusion confirmation for the auditor's file
Hold the First Board Meeting and Appoint the Auditor
The first Board Meeting must be held within 30 days of incorporation. At this meeting, appoint the company's first statutory auditor (who holds office until the conclusion of the first AGM) and pass resolutions for opening the bank account, adopting the common seal (if used), and authorizing routine expenses. File Form ADT-1 to formally notify the Registrar of Companies (ROC) of the auditor appointment.
File Form INC-20A (Declaration of Commencement of Business)
Every company with share capital must file INC-20A within 180 days of incorporation, confirming that subscribers have paid up their subscription money and that the registered office is verified. The company cannot legally commence business or borrow money until this is filed — missing the deadline can attract a penalty on the company and every officer in default, and repeated non-compliance can trigger ROC action to strike the company off the register.
Register for GST (If Applicable)
If aggregate turnover is expected to cross the applicable threshold (currently ₹40 lakh for most goods suppliers and ₹20 lakh for services, with lower ₹10 lakh/₹20 lakh limits in certain special-category states — confirm current thresholds on the GST portal), or if the business makes inter-state supplies, sells on e-commerce marketplaces, or expects to claim input tax credit, register on the GST portal. Even where registration isn't yet mandatory, many founders register voluntarily early on to issue tax invoices and claim ITC on setup costs.

Maintain Statutory Registers and Minute Books
Maintain the registers required under the Companies Act — Register of Members, Register of Directors and KMP, Register of Charges, and minutes of Board and general meetings — either physically or in an approved electronic format. These must be kept at the registered office (or another Board-approved location) and produced on demand during ROC inspections, due diligence, or fundraising.
File Annual Financial Statements — Form AOC-4
AOC-4 carries the audited balance sheet, profit & loss account, and director's report to the MCA. It is due within 30 days of the Annual General Meeting (AGM), and the AGM itself must generally be held within six months of the financial year-end for most private companies (with a further extension possible for the first AGM). Late filing attracts a daily additional fee on top of the normal filing fee, and prolonged default can trigger disqualification of directors under Section 164.
File the Annual Return — Form MGT-7 / MGT-7A
MGT-7 (or the simplified MGT-7A for small companies and OPCs) captures shareholding pattern, director details, and share capital changes over the year. It is due within 60 days of the AGM. Cross-verify the figures against AOC-4 and the share transfer register before filing, since mismatches are a common trigger for ROC scrutiny.
Complete Director KYC — Form DIR-3 KYC
Under the Companies (Appointment and Qualification of Directors) Amendment Rules, 2025 (effective 31 March 2026), DIR-3 KYC moved from an annual filing to a triennial one: every director holding a DIN as on 31 March of a financial year must file the consolidated DIR-3 KYC-Web form once every third financial year, on or before June 30 of that year. Outside that cycle, a director must still file within 30 days of any change to their registered mobile number, email, or address. Missing the applicable deadline deactivates the DIN — which blocks that person from being appointed or continuing as a director on any company's board — until KYC is filed with the late fee (confirm the current fee and cycle year on the MCA portal, since transition-period rules can differ from the steady-state cycle).
Update Changes via DIR-12, INC-22, or PAS-3
Any change in directorship (appointment, resignation, or change in particulars) must be filed on DIR-12 within 30 days. A change in registered office address goes through INC-22, and any allotment of further shares — including ESOPs or a new funding round — is reported via PAS-3, generally within 30 days of the relevant board or shareholder resolution. Keeping these current avoids mismatches between your bank KYC, MCA master data, and cap table.
File Income Tax Return and Tax Audit (If Applicable)
The company must file its income tax return (ITR-6) even in a loss year or with no revenue — a 'NIL' filing does not exempt you from the obligation. Note that the Income-tax Act, 2025 replaced the Income-tax Act, 1961 with effect from April 1, 2026, so income earned from that date onward is governed by the new Act's renumbered sections and 'Tax Year' terminology, while income from FY 2025-26 is still assessed under the old Act — check which regime applies to the period you're filing for. A tax audit becomes mandatory once turnover or gross receipts cross the applicable threshold, and the due date for audited entities typically falls later than the standard ITR deadline. Coordinate the tax audit report with your AOC-4 filing timeline since both draw on the same financial statements.
Set Up TDS Compliance and Periodic Returns
Once the company starts paying salaries, professional fees, or rent above the prescribed thresholds, it must deduct TDS, deposit it monthly, and file quarterly TDS returns (Form 24Q/26Q). Late deposit attracts interest, and late filing of the return attracts a separate late fee — both compound quickly if payroll starts before the finance function is in place.
Renew DSCs and Track the Compliance Calendar
Digital Signature Certificates typically expire after one to two years and must be renewed before they lapse, since almost every MCA and GST filing requires a valid DSC of an authorized signatory. Build a rolling compliance calendar covering AOC-4, MGT-7, the (now triennial) DIR-3 KYC cycle plus any change-based KYC filings, ADT-1 (on auditor reappointment/change), ITR, tax audit, and TDS return due dates so nothing depends on memory alone.
Common mistakes to avoid
- Missing the INC-20A commencement-of-business filing within 180 days, which blocks the company from legally operating or borrowing.
- Filing AOC-4 or MGT-7 late and letting daily additional fees accumulate instead of filing promptly even with incomplete data.
- Letting a director's DIN lapse by skipping the triennial DIR-3 KYC cycle or a required change-based KYC update, which then blocks board actions until it's cleared.
- Not updating the registered office address in MCA records promptly after moving premises, causing notice-delivery and bank KYC mismatches.
- Treating GST registration as optional once past the threshold, or missing the 30-day inter-state supply trigger.
- Assuming a dormant or pre-revenue company is exempt from annual filings — NIL returns are still mandatory.
- Skipping the auditor appointment (Form ADT-1) within 30 days of incorporation, which stalls the entire audit timeline.
- Losing track of DSC expiry dates and discovering it only when a filing deadline is imminent.
Frequently asked questions
What happens if I miss the AOC-4 or MGT-7 filing deadline?
The MCA charges an additional filing fee that accrues per day of delay, on top of the normal fee — this can add up substantially the longer the default continues. Extended non-compliance can also lead to disqualification of directors under Section 164 and, in persistent cases, the company being marked for strike-off by the ROC. It's almost always cheaper to file late than to not file at all.
Is GST registration mandatory if my turnover is still low?
Registration becomes mandatory once aggregate turnover crosses the applicable threshold — commonly ₹40 lakh for goods and ₹20 lakh for services, with lower limits in some special-category states — or if you make inter-state supplies, sell through e-commerce operators, or fall under a category requiring compulsory registration regardless of turnover. Below the threshold, registration is optional but is often taken voluntarily to claim input tax credit and issue GST-compliant invoices to B2B customers. Confirm current thresholds on the GST portal since these have been revised in the past.
Can annual returns be filed entirely online?
Yes. AOC-4, MGT-7/MGT-7A, ADT-1, DIR-3 KYC, and most other ROC forms are filed through the MCA V3 portal using the digital signature of an authorized director or company secretary. E-filing is mandatory for private limited companies — there is no physical filing alternative for these forms.
What if the company has had no business activity since incorporation?
You must still file NIL annual returns (AOC-4, MGT-7) and the income tax return every year — inactivity does not remove the filing obligation. If you genuinely want to pause obligations, the company can apply to be classified as 'dormant' under Section 455 via Form MSC-1, subject to ROC approval and specific conditions, or eventually be struck off voluntarily via Form STK-2 if you intend to wind down.
Do I need a company secretary for post-registration compliance?
A whole-time Company Secretary is mandatory only once the company crosses prescribed paid-up capital or turnover thresholds set under the Companies Act. Below that, most private companies engage a practicing CS or CA on a retainer basis to handle ROC filings, which is common and compliant as long as the filings themselves are accurate and timely.
What is Form INC-20A and why does it matter so much?
INC-20A is the declaration confirming that subscribers to the memorandum have paid up their share subscription and that the registered office has been verified. Until it's filed, the company legally cannot commence business, open certain accounts, or borrow funds — it's one of the few filings with an operational (not just financial) penalty attached.
How often do Digital Signature Certificates need renewal?
Most DSCs issued to directors for MCA and GST filings are valid for one to two years, depending on the class and issuing certifying authority chosen at the time of purchase. Renewal should be initiated a few weeks before expiry since a lapsed DSC blocks time-sensitive filings like AOC-4 and MGT-7.
What penalty applies if I don't appoint an auditor on time?
Failure to appoint the first auditor within 30 days of incorporation (or the shareholders' backup window shortly after) attracts penalties on the company and officers in default, and it also delays every downstream filing that depends on audited financials, including AOC-4 and the tax audit. It's one of the earliest deadlines and easy to miss amid incorporation paperwork.
Is a tax audit always required for a private limited company?
No — a tax audit is triggered once turnover or gross receipts cross the prescribed threshold for the relevant category of business, or in certain presumptive-taxation scenarios. This is governed by the Income-tax Act, 1961 for periods up to FY 2025-26 and by the Income-tax Act, 2025 (in force from April 1, 2026) for periods after that, so confirm which Act and threshold applies to the year you're filing for. Companies below the threshold still file a regular income tax return but don't need a separate tax audit report. Confirm current thresholds with your CA since they are periodically revised.
What's the difference between MGT-7 and MGT-7A?
MGT-7A is a simplified annual return form available to small companies and One Person Companies (OPCs), reducing some of the disclosure burden compared to the standard MGT-7. Whether your company qualifies as 'small' depends on paid-up capital and turnover thresholds under the Companies Act — check eligibility each year since crossing the threshold moves you back to MGT-7.

Yes — our post-incorporation compliance retainer covers ADT-1, INC-20A, AOC-4, MGT-7/7A, DIR-3 KYC, GST registration and returns, and TDS compliance, along with a maintained compliance calendar so deadlines are tracked centrally rather than left to individual founders to remember.
