As per law

Law and sections

  • Income-tax Act, 2025 – replaces the Income-tax Act, 1961 from 1 April 2026
  • Uses one “tax year” instead of previous year and assessment year; sections and forms are renumbered

Who must comply

  • Every taxpayer, deductor and business – contracts, invoices, TDS set-up and policies referring to old sections

Time limits

  • Income up to FY 2025-26 is still assessed under the 1961 Act; tax year 2026-27 onwards under the 2025 Act

If it is missed

  • Using old section codes after the switch can cause TDS mismatches, defaults on TRACES and notices
