Which law applies when filing the return for income earned in FY 2025-26?
The Income Tax Department states that income earned during FY 2025-26 is filed for AY 2026-27 under the Income-tax Act, 1961, even though the Income Tax Act, 2025 came into force from 1 April 2026. Tax Year 2026-27 is the first period governed by the new Act.
A reliable ITR filing sequence
The filing form is the output of the tax facts, not the starting point. A robust filing workflow begins by identifying the relevant year, residence status, income categories, tax credits and filing history.
- Confirm the relevant financial year / assessment year or tax year.
- Identify every material income source before selecting a return form.
- Reconcile tax credits and information statements before submission.
- Resolve obvious mismatches rather than copying pre-filled data without review.
- Complete verification and then monitor processing, refund or notices.
Why AY 2026-27 needs special attention
The 2026 filing season sits across a statutory transition. The official Income Tax Department FAQ makes clear that returns relating to FY 2025-26 remain governed by the 1961 Act, while the new Tax Year framework applies prospectively from 2026-27.
Do not mix the legal framework for AY 2026-27 with the new Tax Year 2026-27 merely because both are being discussed during calendar year 2026.
What to reconcile before filing
Form 16, salary and interest records, capital-gains statements, business or professional books, AIS, Form 26AS and prior-return information may all affect the return. The relevant set depends on the taxpayer facts.
- Income records
- TDS/TCS and tax-payment records
- AIS and Form 26AS
- Capital-gains and investment records where relevant
- Business or professional accounts where relevant
- Foreign-income / NRI records where relevant
