AY 2026-27 is not Tax Year 2026-27
- AY 2026-27 relates to FY 2025-26 income and is handled under the Income-tax Act, 1961.
- Tax Year 2026-27 relates to FY 2026-27 income and is handled under the Income Tax Act, 2025.

Claims that need source verification

- Payroll allowance changes such as HRA city expansion or perquisite valuation changes.
- TCS/TDS rate changes attributed to a future tax year.

How employers and CAs should verify
- Check live e-filing/TRACES/GST portal screens.
- 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.
What a serious tax expert should verify
