Compliance Calendar
Tax Compliance Calendar 2026–27
Every due date that matters for Indian taxpayers — ITR filing, advance tax, TDS deposits, GST returns — with penalty amounts and official source citations.
Introduction
Every year, Indian taxpayers must meet several deadlines for filing returns, paying advance tax, depositing TDS, and filing GST returns. Missing a deadline can mean a penalty ranging from ₹1,000 to ₹5,000, plus interest charges. This calendar lists every key compliance date for FY 2026-27 — ITR filing deadlines for individuals and businesses, advance tax installment dates, TDS deposit due dates, and GST return filing windows. Each entry shows the deadline, who it applies to, and the penalty for late filing. All dates are verified against the Income Tax Act 2025, CBDT circulars, and GST Council notifications published on the official government portals.
