Income tax return documents and filing checklist for ITR season in India

Most filing-season stress comes from one thing: chasing paperwork at the last minute. Gather these before you sit down to file and the return almost takes care of itself.

Income documents

  • Form 16from each employer you worked for in the year.
  • Form 26AS and AIS/TISyour consolidated tax statement — cross-check every entry against your own records.
  • Interest certificatesfrom banks and post office for savings and fixed deposits.
  • Capital gains statementsfrom brokers and mutual fund houses if you sold any investments.

Deduction proofs

If you're on the old regime, keep evidence for everything you claim — 80C investments, health insurance premiums (80D), home loan interest and principal, and donations.

Reconcile your AIS with your bank statements before you file, not after a notice arrives. Mismatches are the single most common reason returns get picked up.

In short

Income proofs, tax-credit statements and deduction evidence — collected in one folder before you start. If anything doesn't tally, that's the moment to ask, not on the last day.
