India Compliance Calendar 2026: Key Deadlines for Businesses

Most compliance failures aren't caused by not knowing the rule — they're caused by a deadline arriving unnoticed among a dozen other recurring obligations. A single calendar view makes the pattern easier to plan around.

Monthly, Every Month

• 7th — TDS/TCS deposit for the previous month
• 11th — GSTR-1 (monthly filers)
• 15th — PF and ESI contribution deposit
• 20th — GSTR-3B (monthly filers)

Quarterly

• TDS returns (24Q/26Q/27Q) — 31 Jul, 31 Oct, 31 Jan, 31 May
• GSTR-1 and GSTR-3B for QRMP-scheme taxpayers
• Advance tax installments — 15 Jun, 15 Sep, 15 Dec, 15 Mar

Annual, Fixed Dates

• 30 September — Tax audit report filing, DIR-3 KYC for directors
• 31 October — ITR filing where tax audit applies
• 31 December — GSTR-9 annual return, and the general (non-audit) ITR due date in recent years
• AOC-4/MGT-7 — Within 30/60 days of the AGM (AGM itself due within 6 months of financial year-end)

Because several of these deadlines (AOC-4, MGT-7, ADT-1) are calculated relative to your own company's AGM date rather than a fixed calendar date, a generic calendar only gets you most of the way — the last step is always mapping these against your specific entity's actual filing history.
