ITR Filing 2025: Essential Documents Checklist for a Smooth Income Tax Return Process

Planning to file your Income Tax Return (ITR) for AY 2025–26? Before you get started, make sure you’re well-prepared. While you can begin filing after receiving Form 16 and accessing your updated Annual Information Statement (AIS), it’s crucial to start collecting the right documents early to avoid last-minute hassles.

ITR Filing Season 2025 Begins

The Income Tax Department has officially released the updated ITR forms for Financial Year 2024–25 (Assessment Year 2025–26). These forms include key updates from the Union Budget 2024, especially around capital gains tax rules. However, online filing utilities are still awaited, and most salaried individuals are yet to receive their Form 16 from employers.

That said, the due date—July 31, 2025—is approaching fast. Begin your return preparation by collecting the necessary financial and personal documents.

List of Important Documents for ITR Filing 2025

1. Form 16 from all employers (especially if you’ve changed jobs)
2. Aadhaar Card & PAN Card – ensure they are linked
3. Form 26AS and Annual Information Statement (AIS)
4. Bank account statements and TDS certificates
5. Previous year’s tax returns
6. Salary slips – including any income earned overseas
7. Rent receipts and rental agreements (for claiming HRA)
8. Statements of foreign bank accounts or investments
9. Form 67 (for claiming foreign tax credit under DTAA)
10. Details of assets and liabilities (mandatory if income exceeds ₹50 lakh)

Choosing the Right ITR Form

Even though ITR-1 (Sahaj) has been simplified, it now accommodates certain capital gains—such as those from equity shares and mutual funds (up to ₹1.25 lakh annually)—subject to conditions. However, using the wrong form can lead to your return being marked as defective.

New vs. Old Tax Regime: Preserve These Documents

With Budget 2025 proposing enhanced tax rebate limits (up to ₹12 lakh) and relaxed slabs under the new tax regime, many taxpayers are expected to switch. However, for FY 2024–25, if you initially opted for the new regime with your employer but now plan to revert to the old one, you’ll need proof of eligible deductions.

📝 Note: You are not required to attach these documents with your ITR. But keep them ready for verification if discrepancies arise in Form 16, AIS, or Form 26AS.
