ITR 2026: Business Filers on ITR-3/ITR-4 Now Get a Permanent 31 August Due Date

Written by Timo Vikson • Published on 14 Jul 2026 • Read time minutes

Good news for proprietors, freelancers and professionals: the Finance Act 2026 amended Section 139(1) so that non-audit taxpayers filing ITR-3 or ITR-4 get until 31 August of the assessment year — every year, permanently. This is a statutory change, not a one-time extension.

The AY 2026-27 dates

  • 31 July 2026 — salaried filers on ITR-1/ITR-2.
  • 31 August 2026 — business and professional filers on ITR-3/ITR-4 (non-audit).
  • 31 October 2026 — audit cases.

A related relaxation: revised returns under Section 139(5) can now be filed up to the end of the assessment year — 31 March 2027 for AY 2026-27.

What to do

Don’t burn the extra month — GST-vs-books reconciliation is the top notice trigger for small businesses. Start early, file calm. WeeDoo can handle your ITR filing.
