The Finance Act 2026 amended Section 139(1) to give this category a permanent August 31 deadline rather than the general July 31 one. Quick decision guide: Salaried only (ITR-1 or ITR-2): July 31, 2026 Freelancers/consultants with professional income, presumptive tax under 44ADA or 44AD (ITR-3 or ITR-4): August 31, 2026 Tax audit cases under Section 44AB: October 31, 2026 Transfer pricing cases: November 30, 2026 One practical point: even if your deadline is August 31, filing in the first week of August is safer.
