New Income-tax Act 2025 Transition Calendar for Employers

Finin2min Tax Desk·June 2026·7 min readPAYROLL 2026

Employers will feel the Income-tax Act, 2025 through payroll declarations, proof collection, TDS logic, employee FAQs and year-end certificates. A clean transition needs HR, payroll, finance and tax to work from the same calendar.

Employer transition objective

The Income-tax Act, 2025 comes into force from 1 April 2026, and the Department’s transition FAQ confirms repeal of the 1961 Act with savings for old/pending matters. Employers should therefore separate “current payroll under the 2025 Act” from “old-year corrections or disputes under the 1961 Act”.
