Filing your Income Tax Return (ITR) correctly and on time is essential for avoiding penalties, claiming deductions, and maintaining financial credibility. As we approach the Assessment Year 2025-26, it's important to prepare the right documents before you begin.
Here's a complete checklist of documents you need to file your ITR smoothly and accurately.

1. PAN Card
Your Permanent Account Number (PAN) is your unique identification for all tax-related matters. It's mandatory for ITR filing.
2. Aadhaar Card
As per the Income Tax Act, quoting your Aadhaar number or Aadhaar enrollment number is mandatory while filing ITR.
3. Form 16 (For Salaried Individuals)
Issued by your employer, Form 16 contains details of your salary income and TDS deducted. It helps in accurately declaring your income and tax already paid.
4. Salary Slips (Optional but Helpful)
If there are multiple salary components or if you changed jobs, having monthly salary slips ensures correct income reporting.
5. Bank Account Statements
Useful for:
- Reporting interest income from savings accounts
- Verifying large deposits or transactions
- Claiming correct deductions under Section 80TTA/80TTB
6. Investment Proofs for Deductions
To claim deductions under various sections like:
- Section 80C: LIC premium, PPF, ELSS, tuition fees, etc.
- Section 80D: Medical insurance premium
- Section 80E: Education loan interest
- Section 80G: Donations made
7. Home Loan Statement
Required to claim:
- Interest under Section 24(b) (up to ₹2 lakh)
- Principal repayment under Section 80C
8. Capital Gains Statements
If you have sold:
- Shares/Mutual Funds
- Property or land
Include capital gain/loss details, holding period, and indexation benefits.
9. Rental Income Details (if applicable)
Include:
- Total rent received
- Municipal taxes paid
- Interest on housing loan (if any)
This helps in calculating Net Annual Value (NAV) for income from house property.
10. Advance Tax or Self-Assessment Tax Receipts
If you've paid advance tax during the year (like in case of business income, capital gains, or F&O), preserve challan receipts (ITNS 280).
11. Foreign Income / Assets (if applicable)
If you have:
- Foreign bank accounts
- Overseas assets or income
These must be reported in the return as per Black Money Act compliance.
12. TDS Certificates (Form 16A, 26AS, AIS)
- Cross-check TDS entries in Form 26AS and AIS (Annual Information Statement)
- Form 16A for TDS on non-salary income (like interest, commission, etc.)
Pro Tip: Start collecting these documents in April itself - it'll make your ITR filing quick, stress-free, and error-free.
