Startup Compliance Calendar: Every Filing in Your First Two Years

Updated 2026-08-26 · 6 min read · By KyaTax
Quick answer
  • A startup in India faces at least 20 mandatory filings in its first two years — missing even one can trigger penalties of ₹200 per day or more.
  • Your compliance load depends on your legal structure: a private limited company has far more filings than a sole proprietorship or LLP.
  • Getting your calendar right from Day 1 costs almost nothing; fixing missed filings later can cost lakhs in late fees and professional charges.

If you launched a startup in FY 2025-26 or are launching one in FY 2026-27, here is the practical bottom line: you will need to file returns for GST, TDS, income tax, and ROC every single year — and some of these are monthly. Missing them is not a "pay a small fine and move on" situation. Penalties compound, directors can be disqualified, and GST registrations can be cancelled. This calendar covers every major filing for a private limited company in its first two years, with exact due dates, rupee-level penalties, and a worked example so you know what the numbers actually look like.

Your Legal Structure Determines Your Compliance Load

Before listing dates, understand this: a private limited company (Pvt Ltd) has the heaviest filing load. An LLP is lighter. A sole proprietorship has the lightest. Most funded startups are Pvt Ltd, so this calendar focuses there — but the GST and TDS sections apply to all structures.

Month-by-Month Startup Compliance Calendar (FY 2026-27)

The table below covers the core filings. Due dates assume a Pvt Ltd company with GST registration and at least one salaried employee.

Filing Frequency Due Date Penalty for Late Filing
GSTR-3B (monthly turnover above ₹5 crore) Monthly 20th of next month ₹50/day (₹20/day if nil return); interest at 18% p.a. on tax due
GSTR-3B (quarterly, QRMP scheme, turnover ≤ ₹5 crore) Quarterly 22nd or 24th of month after quarter (state-wise) ₹50/day; interest at 18% p.a.
GSTR-1 (monthly) Monthly 11th of next month ₹50/day (₹20/day if nil)
GSTR-1 (quarterly, QRMP) Quarterly 13th of month after quarter ₹50/day (₹20/day if nil)
TDS Return (Form 24Q — salary) Quarterly 31 Jul / 31 Oct / 31 Jan / 31 May ₹200/day under Section 234E (max = TDS amount)
TDS Return (Form 26Q — non-salary) Quarterly 31 Jul / 31 Oct / 31 Jan / 31 May ₹200/day under Section 234E
TDS Deposit Monthly 7th of next month (March TDS: 30 April) Interest at 1.5% per month from deduction date to deposit date
Advance Tax (if tax liability ≥ ₹10,000) 4 instalments 15 Jun / 15 Sep / 15 Dec / 15 Mar Interest under Sections 234B and 234C
ITR Filing (company) Annual 31 October (audit cases) ₹5,000 late fee (₹1,000 if turnover ≤ ₹5 lakh); Section 234F
Tax Audit Report (Form 3CA/3CB + 3CD) — if turnover > ₹1 crore (business) or ₹50 lakh (professional) Annual 30 September 0.5% of turnover or ₹1.5 lakh, whichever is lower
ROC Annual Return (Form MGT-7A for small companies) Annual Within 60 days of AGM (AGM by 30 Sep; so MGT-7A by 28/29 Nov) ₹100/day of default
ROC Financial Statements (Form AOC-4) Annual Within 30 days of AGM (by 30 Oct) ₹100/day of default
DIR-3 KYC (director KYC) Annual 30 September ₹5,000 to reactivate DIN if missed
Form INC-20A (commencement of business) One-time Within 180 days of incorporation ₹50,000 on company; ₹1,000/day on officers

The First 6 Months: One-Time Filings You Cannot Ignore

Most founders miss these because they are not recurring and no one sends you a reminder:

  1. INC-20A — Declaration of commencement of business. File within 180 days of incorporation. Without this, your company legally cannot borrow money or exercise borrowing powers. Penalty is steep: ₹50,000 on the company and ₹1,000 per day on every officer in default.
  2. GST Registration — Mandatory once turnover crosses ₹20 lakh (₹10 lakh in special category states). If you are selling to other businesses and want your customers to claim input tax credit, register voluntarily from Day 1 even below the threshold.
  3. TAN Registration — Required before you pay any salary or make any payment attracting TDS. Apply on the NSDL portal. There is no prescribed time limit, but you need it before the first TDS payment.
  4. Shops and Establishments Registration — State-level requirement. Most states require this within 30 days of opening. Penalties vary by state.
  5. Professional Tax Registration — Required in states like Maharashtra, Karnataka, West Bengal. Register and pay monthly or annually as the state prescribes.

Worked Example: TDS on a ₹12,00,000 Salary Package

Say your startup hires its first employee in April 2026 at a CTC of ₹12,00,000 per year (₹1,00,000 per month). The employee opts for the new tax regime. Here is what your TDS obligation looks like:

You must deposit ₹4,550 by the 7th of the following month and file Form 24Q quarterly. If you deposit even one day late, interest of 1.5% per month accrues from the date of deduction. On ₹4,550, that is about ₹68 per month — small, but the 234E penalty of ₹200 per day for a late quarterly return can quickly exceed the TDS itself.

ROC Filings: What a Private Limited Company Must Do Every Year

The Companies Act imposes a strict annual cycle even if your company has zero turnover:

A startup with zero revenue still pays a CA for a statutory audit and still files AOC-4 and MGT-7A. Budget at least ₹15,000–₹25,000 per year for this even at the small-company level.

Common Mistakes Founders Make With Compliance

How to Actually Stay on Top of This

The single most practical thing you can do is build a shared Google Calendar with every due date listed above and set reminders 10 days in advance. Pair that with a Compliance Checkup at the start of each financial year to catch anything that has slipped. For most seed-stage startups, the realistic annual compliance cost runs between ₹40,000 and ₹1,20,000 depending on the number of employees, GST transactions, and whether you need a tax audit — budgeting for this upfront is far cheaper than paying penalties and professional fees to clean up a backlog.

Frequently asked questions

What is the penalty for not filing INC-20A for a new company?

The company faces a penalty of ₹50,000, and every officer in default (typically directors) faces ₹1,000 per day for every day the default continues. More seriously, a company that has not filed INC-20A and has not commenced business within two years of incorporation can be struck off by the Registrar of Companies under Section 248 of the Companies Act, 2013.

Does a startup with zero revenue still need to file GST returns?

Yes, if you are GST-registered. You must file nil returns for every period in which you had no transactions — both GSTR-1 and GSTR-3B. The penalty for a nil return is lower (₹20 per day instead of ₹50 per day) but it still accrues. Persistent non-filing can lead to cancellation of your GST registration, which is painful to reverse.

Is a statutory audit compulsory for a private limited company even if turnover is zero?

Yes. The Companies Act, 2013 makes statutory audit mandatory for every private limited company regardless of turnover or age. You must appoint a Chartered Accountant as auditor within 30 days of incorporation (or at the first AGM), get your accounts audited, and file the audited financials with the ROC every year. There is no minimum turnover threshold for this requirement.

What is the QRMP scheme and should a new startup use it?

QRMP (Quarterly Return Monthly Payment) is a GST scheme for taxpayers with annual turnover up to ₹5 crore. Under QRMP, you file GSTR-1 and GSTR-3B quarterly instead of monthly, but you still pay tax monthly through a fixed-sum or self-assessed payment. For a new startup with low and irregular sales, QRMP can reduce paperwork significantly. However, if your B2B customers need your invoices reflected on the portal quickly for their input tax credit, monthly filing may be better for your business relationships.
