  • TCS/TDS rate changes attributed to a future tax year.

Safe workflow

How employers and CAs should verify

  • Retain notification number, form instruction PDF or validation-rule PDF with the working paper.
  • Do not update payroll or client advice from competitor snippets alone.

Applicable year and source discipline

Last fact-checked: 25 May 2026.

AY 2026-27 means FY 2025-26 income and is still filed under the Income-tax Act, 1961 using forms/instructions for that assessment year. Tax Year 2026-27 means FY 2026-27 income under the Income Tax Act, 2025. The two should not be mixed.

Where this page discusses a new form, rate, portal label or transition item, treat it as usable only when supported by the live e-filing portal, a CBDT notification, the Income Tax Department guidance page, the supplied Act PDF, or ICAI material.
