Annual Filing Deadline Calendar 2026-27

The Annual Filing Deadline Calendar: Every Due Date in One Place

Income tax has its calendar. The ROC has another. TDS runs quarterly. GST runs monthly. If you run a business in India, especially after completing Private Limited Company Registration In India, you’re effectively managing four overlapping calendars — and any one missed date starts a penalty meter. This master calendar merges them all, month by month. Scroll to your busy months, then download the printable wall version at the end.

Missed a Deadline Already? Your Recovery Options

Belated return — file by 31 December with late fee under Section 234F (₹5,000; ₹1,000 if income ≤ ₹5 lakh).
Revised return — filed but found an error? Correct it by 31 December.
ITR-U (Updated Return)** — missed even that? File for past years within 48 months of the assessment year’s end by paying additional tax. Late, but legal — and far cheaper than a notice.
Foreign remittances pending? Don’t forget 15CA-CB certification before remitting — banks won’t process without it.
