Form 16 vs AIS vs Form 26AS: How to Reconcile Tax Differences Before Filing ITR

August 01, 2026 • 7 min read

When preparing to file your Income Tax Return (ITR) in India, relying solely on your employer's Form 16 can lead to tax notices if unreported income appears on your Annual Information Statement (AIS) or Form 26AS.

Understanding the Three Core Tax Documents

  • Form 16: Issued by your employer, detailing gross salary, HRA exemptions, Section 80C deductions, and TDS deducted under Section 192.
  • Form 26AS: A tax credit ledger managed by the Income Tax Department of India showing TDS, TCS, and advance tax payments.
  • Annual Information Statement (AIS): A comprehensive summary tracking stock dividend payouts, savings account interest, FD interest, and mutual fund redemptions.

    • How to Reconcile Discrepancies

    Before submitting your return, aggregate all interest and capital gains reported in AIS alongside your salary. You can verify your exact net tax liability or refund using our live Income Tax Calculator.

    Input your Form 16 and AIS income values to calculate exact Old vs New Regime tax payable.

    Handling Mismatches in Dividend & Interest Income

    If your AIS reports interest income from bank fixed deposits or savings accounts that was omitted from Form 16, add these figures under 'Income from Other Sources'. Check your total interest growth using our FD Calculator.
