Old section 271F (Penalty for failure to furnish return of income.) corresponds to marked redundant by the navigator (no separate provision) of the Income-tax Act, 2025, according to the Income Tax Department’s navigator. As marked by the navigator.

Which Act applies

The 2025 Act came into force on 1 April 2026 (its section 1(3)). Income of FY 2025-26 and earlier is dealt with under the 1961 Act (the Act’s section 536 and the CBDT’s transition FAQs, Q1.7 and Q1.12), so for those years the old section number is still the one that applies. For tax year 2026-27 onwards use the new number.
