There's no single deadline this year. AY 2026-27 runs on a staggered calendar:

If you're a business owner or professional filing ITR-3/4 without audit — you still have time, but the clock's ticking. Don't wait for an extension; last year's deadline was pushed only because forms and utilities came late — this year everything arrived on schedule, so no extension is expected.

Missed 31 July already? No panic — you can still file a belated return by 31 December 2026 under Section 139(4), but it comes at a cost.

  • Late fee under Section 234F: ₹1,000–₹5,000
  • 1% monthly interest under Section 234A on any unpaid tax
  • Loss of the right to carry forward capital/business losses to future years
