Section FinderSection 234F of the Income-tax Act, 1961: now section 428
Old section 234F (Fee for default in furnishing return of income.) corresponds to section 428 of the Income-tax Act, 2025, according to the Income Tax Department’s navigator. Checked against the Act: the new section is about the same subject.
The first words of the new section
428. Without prejudice to the provisions of this Act, where, a person required to furnish a return of income under section 263 fails to do so within such time as may be prescribed in section 263(1), he shall pay, by way of a fee,–– (a) a sum not exceeding ₹ 1000, if the total income of such person does not exceed ₹ 500000; (b) a sum of ₹5000, in any other case.…

What the sources say
The Act's section 428 sets the fee for filing the return late: up to ₹1,000 where total income is not more than ₹5,00,000 and ₹5,000 otherwise (text read from the Act). The CBDT's FAQs (Q3.8) state the same for the old Act's 234F.
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.
