Every statutory date a private limited company in India has to hit, in one page: GST returns, TDS, advance tax, ROC filings and PF/ESI. Miss one and the penalty is usually larger than the tax.
The next filings from today. Dates that fall on a weekend or holiday usually move to the next working day.

What is due every month, quarter and year, whichever year it is.
Goods and services tax. Monthly returns if you are on the regular scheme, quarterly under QRMP.
| Filing | Due |
|---|---|
| GSTR-1 Statement of outward supplies: every sales invoice raised in the month. Businesses on the QRMP scheme file this quarterly instead. | 11th of the following month |
| GSTR-3B Summary return where the tax is actually paid, netting output tax against input tax credit. Late filing accrues interest and a daily fee. | 20th of the following month |
| GSTR-9 Annual consolidation of the year returns for the financial year that ended the previous March. | 31 December |
Tax deducted at source on salaries, contractors, rent and professional fees. Deposit monthly, report quarterly.
| Filing | Due |
|---|---|
| TDS deposit Pay over the tax deducted from salaries, contractor invoices, rent and professional fees. March deductions get an extended date. | 7th of the following month |
| TDS return (Form 24Q / 26Q) Quarterly statement of what was deducted and deposited. 24Q covers salaries, 26Q covers everything else. | 31st after each quarter |
Pay your estimated income tax across the year in four instalments rather than at the end.
| Filing | Due |
|---|---|
| First instalment (15%) Pay 15% of the estimated tax for the year. Underpaying accrues interest, so estimate on the high side if the year is uncertain. | 15 June |
| Second instalment (45% cumulative) Top up so the total paid for the year reaches 45% of the estimate. | 15 September |
| Third instalment (75% cumulative) Top up so the total paid reaches 75% of the estimate. | 15 December |
| Fourth instalment (100% cumulative) Settle the full estimated liability before the financial year closes. | 15 March |
Annual filings with the Ministry of Corporate Affairs. Every private limited company has these, profitable or not.
| Filing | Due |
|---|---|
| DIR-3 KYC Annual identity verification for each director. Missing it deactivates the DIN and carries a flat penalty to reactivate. | 30 September |
| ADT-1 Notify the MCA of the auditor appointed at the annual general meeting. | Within 15 days of the AGM |
| AOC-4 File the audited financial statements for the year that ended in March, within 30 days of the AGM. | 30 October |
| MGT-7 Annual return covering shareholding, directors and company details, within 60 days of the AGM. | 29 November |
Provident fund and state insurance contributions, once you cross the employee thresholds.
| Filing | Due |
|---|---|
| EPF contribution Deposit employee and employer provident fund contributions for the previous month. | 15th of the following month |
| ESI contribution Deposit employee state insurance contributions for the previous month. | 15th of the following month |
This is a reference, not tax advice. The government extends these dates fairly often, thresholds change with each budget, and what applies to you depends on your turnover, headcount and registrations. Confirm anything that costs money with your CA.
Four recurring streams plus payroll: monthly or quarterly GST returns if you are registered, monthly TDS deposits with quarterly returns if you deduct tax at source, four advance tax instalments across the year, and the annual ROC filings (AOC-4, MGT-7, DIR-3 KYC, ADT-1). Add EPF and ESI once you cross the employee thresholds. The ROC filings apply whether or not you made money.
On the regular monthly scheme, GSTR-1 is due on the 11th of the following month and GSTR-3B on the 20th. The annual GSTR-9 is due on 31 December for the financial year that ended the previous March. Businesses on the QRMP scheme file GSTR-1 quarterly instead.
15 June for 15% of your estimated annual tax, 15 September for 45% cumulative, 15 December for 75%, and 15 March for the full 100%. It applies once your expected liability for the year passes Rs. 10,000, and underpaying accrues interest.
It depends on the filing. GST late fees accrue per day plus interest on the unpaid tax. ROC filings carry a daily additional fee that grows quickly. Missing DIR-3 KYC deactivates the director DIN and costs a flat fee to restore. None of it is fatal, but it is nearly always cheaper to file on time than to argue later.
Yes. A dormant private limited company still files its annual ROC returns and, if registered, nil GST returns. Being pre-revenue removes the tax, not the filing.
Yes. Runway has this calendar built in and marks each deadline against your company, alongside the revenue, burn and runway pulled from your accounting and payment tools. It is free for founders.
