ITR Filing Due Date 2025: What taxpayers must pay attention to before filing returns–A complete last-minute guide

ITR Filing Deadline: With the due date for filing income tax returns (ITR) drawing closer, lakhs of taxpayers are rushing to finish the process. The Income Tax Department has given extra time this year, extending the deadline for Assessment Year 2025-26 to September 15, 2025. The earlier deadline was July 31.

As per officials, the extension was needed because of major changes in ITR forms and the time required to update the filing system.

ITR: What taxpayers need before filing

Before sitting down to file returns, taxpayers should keep ready Form 16 from their employer, Form 26AS, the Annual Information Statement (AIS), PAN and Aadhaar details, bank and investment proofs, and receipts for home loan interest or insurance payments.

Choosing the right ITR form

To prevent wrong filings, the correct ITR form needs to be selected.

• ITR 2: For individuals having capital gains or more than one house property but not carrying on business.
• ITR 3: For persons having income from business or profession, including freelancers and self-employed persons.
• ITR 4 (Sugam): Presumptive basis income of desiring Rs 50lakhs from small business or profession.
• ITR 5: For firms, LLPs, AOPs, BOIs, societies, and certain legal entities.

Double-checking your income records

Taxpayers should carefully check Form 26AS and AIS to make sure all income, including salary, interest, and other earnings, is correctly reported.

Don’t miss deductions

The choice of tax regime matters.

• Old regime: Allows a wide range of deductions, including under sections 80C, 80D, home loan interest, NPS contributions, donations, and education loan interest.
• New regime: Provides fewer deductions but includes relief on housing loan interest and employer contributions to NPS.
