Month-by-month income tax, TDS, advance tax, GST, ROC and payroll compliance calendar for AY 2026-27 (FY 2025-26). Includes salaried, freelancer, business and founder calendars with downloadable checklists, penalty tables and 30+ FAQs.
Tax compliance in India is a year-long sport. Missing the 15 June advance tax due date can cost you 1% per month in interest. Missing the 31 July ITR deadline triggers a ₹5,000 late fee plus 1% interest. Missing the 7th of any month for TDS deposit triggers 1.5% per month plus disallowance of expenses. This is the only calendar you'll need for AY 2026-27 (FY 2025-26) — bookmark it, share it with your CA, and set phone reminders for every date in this guide.
It is the master timeline of every recurring obligation the Income Tax Act imposes on individuals, businesses, deductors and collectors during a financial year. India's tax year runs 1 April to 31 March (FY 2025-26 = AY 2026-27). Each financial year carries 40+ compliance touchpoints — advance tax, TDS deposits, TDS returns, TCS returns, ITR filing, tax audit, transfer pricing audit, SFT filings, and so on.
| Compliance | Penalty for delay |
|---|---|
| TDS deposit | Interest @1.5% per month + 30% expense disallowance u/s 40(a)(ia) |
| TDS return | Late fee ₹200/day u/s 234E + penalty ₹10k-1L u/s 271H |
| Advance tax shortfall | Interest @1% per month u/s 234B and 234C |
| ITR late filing | ₹1,000 (income ≤ ₹5L) or ₹5,000 (above) u/s 234F + 1% per month u/s 234A |
| Tax audit report | 0.5% of turnover, max ₹1,50,000 u/s 271B |
| Loss carry-forward | LOST permanently if ITR filed after due date |
Missing the 31 July deadline disqualifies you from carrying forward business loss, capital loss and house property loss (other than self-occupied). That alone can cost lakhs.
