ITR Forms for AY 2026-27: Detailed Guide, New Rules and Practical Compliance Tips

1. Background – Why Choosing the Correct ITR Form Matters

For every Assessment Year, the Income Tax Department prescribes specific Income Tax Return (ITR) forms tailored to different assessee categories. For AY 2026-27 (corresponding to FY 2025-26), seven distinct ITR forms have been notified, each meant for particular types of income and entities.

Filing your return in an incorrect form is not a mere technical defect – under Section 139(9), such a return is treated as defective, and if the defect is not cured within the stipulated time, it is deemed that no return has been filed at all. This can affect:

  • Carry-forward of losses
  • Claim of refunds
  • Interest and penalty exposure
  • Compliance with other provisions under the Income Tax Act 1961
