Documents Required to File ITR for FY 2025-26 (AY 2026-27): Complete Checklist
Quick Summary

The short version

To file your income tax return for FY 2025-26 (AY 2026-27) you need your PAN and Aadhaar, Form 16 if you are salaried, your AIS and Form 26AS, bank interest and capital-gains statements, and — only if you choose the old tax regime — proof of deductions such as…

Everyone needs these

  • PAN, linked with your Aadhaar. If PAN is inoperative because it isn't linked, refunds are held back.
  • Aadhaar, for e-verification by OTP.
  • Annual Information Statement (AIS) and Taxpayer Information Summary (TIS), from the e-filing portal under Services → AIS. They show the income the department already knows about: salary, interest, dividends, share and mutual fund sales, large transactions.
  • Form 26AS: TDS and TCS credited against your PAN, and any advance or self-assessment tax paid.
  • Bank account details for every account you held. The one for your refund must be pre-validated on the portal.

Start with the AIS. Anything it shows that you leave out of your return is the most common reason for a notice.

Documents by type of income

IncomeDocuments
Salary or pensionForm 16 from each employer (issued by 15 June), salary slips, Form 12BA for perquisites if any
InterestInterest certificates from banks and post office, including savings and FD interest

Foreign income or assetsForeign bank and investment statements, Form 67 if claiming foreign tax credit

Deduction proofs: only if you choose the old regime

The new tax regime is the default and allows few deductions. For FY 2025-26 it gives a standard deduction of ₹75,000 to salaried people and pensioners, and a rebate that brings the tax to nil on income up to ₹12 lakh (not counting special-rate income such as capital gains).

If you opt for the old regime, keep proofs for what you claim:

  • Section 80C (up to ₹1.5 lakh): PPF, ELSS, life insurance premium, tuition fees, home-loan principal, EPF.
  • Section 80D: health insurance premium receipts.
  • HRA: rent receipts and the rent agreement. You also need the landlord's PAN if the rent is over ₹1 lakh a year.
  • Home-loan interest: the lender's interest certificate.
  • Section 80G: donation receipts with the charity's registration number.
  • Section 80E: education-loan interest certificate.

Employer contributions to NPS (section 80CCD(2)) are allowed under both regimes.

Which ITR form do you need?

FormFor
ITR-1 (Sahaj)Resident individuals with income up to ₹50 lakh from salary or pension, house property, interest and other sources, and small long-term gains on listed shares or equity funds (up to ₹1.25 lakh)
ITR-2Individuals and HUFs with capital gains beyond ITR-1's limits, foreign income or assets, or income over ₹50 lakh, but no business income
ITR-3Individuals and HUFs with income from a business or profession
ITR-4 (Sugam)Residents with presumptive business or professional income and total income up to ₹50 lakh

Deadlines and what happens if you are late

  • Missed the original due date for FY 2025-26? You can still file a belated return until 31 December 2026. The late fee is up to ₹5,000, or ₹1,000 if total income is ₹5 lakh or less, plus interest on any tax due. Some losses cannot be carried forward from a belated return.
  • After that, an updated return (ITR-U) can be filed within 48 months of the end of the assessment year, with additional tax.
  • Whatever you file, e-verify it within 30 days. Until then it isn't treated as filed.

Coming up: the Income-tax Act, 2025 applies from 1 April 2026, so from the 2026-27 tax year several forms are renumbered. Form 16, for example, becomes Form 130. Returns for FY 2025-26 are still filed under the old Act.
