MSME Compliance Checklist India 2026-27: GST, Income Tax & TDS Due Dates for Small Businesses

Running an MSME in India means juggling GST returns, income tax deadlines, and TDS compliance — all at once. Missing even one deadline can trigger late fees, interest, or notices. This guide gives you the complete FY 2026-27 compliance calendar so you never miss a due date again.

Why MSMEs Struggle with Compliance

Most MSMEs don't have a dedicated tax team. A single missed GST filing or TDS deposit can snowball into penalties that hurt cash flow. The good news — once you have a clear calendar, staying compliant becomes routine. Tools like SNexa MSME Compliance Manager are built exactly for this problem — tracking GST, Income Tax, and TDS deadlines in one dashboard so nothing slips through the cracks.

GST Return Due Dates FY 2026-27

GSTR-1 — 11th of every month

GSTR-3B — 20th of every month (monthly filers)

QRMP filers — 22nd/24th of the month following the quarter

CMP-08 (Composition scheme) — 18th of the month following the quarter

GSTR-9 (Annual Return) — 31st December 2027 for FY 2026-27

Managing multiple GST due dates manually is where most MSMEs slip up. This is exactly the kind of tracking automated inside SNexa MSME Compliance Manager.
