Old Income-tax Act 1961 vs Income-tax Act 2025: Section Number Finder

Finin2min Tax Desk·June 2026·7 min readSECTION MAP

The biggest risk in the Income-tax Act 2025 transition is not the new law itself; it is using old section numbers casually in new-year content. A section finder should be based on the official comparison utility, not memory or third-party summaries.

Use the official comparison utility first

The Income Tax Department provides an official utility to check provisions of the Income-tax Act, 1961 vis-à-vis the Income-tax Act, 2025. This should be the first stop before publishing any “old section vs new section” table.

Where section mapping matters

Do not overclaim “unchanged”

Even where substance appears similar, article writers should avoid saying “no change” unless the official section, schedule and transition rule have been checked. Safer wording is: “verify against the official 2025 Act section and transition FAQ before filing.”
