Form 26AS vs AIS vs TIS: What’s the Difference and Which One to Check Before Filing ITR?

Many taxpayers are confused between Form 26ASAIS (Annual Information Statement), and the newer TIS (Taxpayer Information Summary) — all available on the Income Tax Portal.

But if you file ITR without checking these, you could miss TDS credits, underreport income, or trigger notices.


1. What Is Form 26AS?

  • Traditional TDS summary form
  • Shows TDS deductedadvance tax paidrefunds issued
  • Data from employers, banks, and deductors
  • Still important — but not enough anymore

2. What Is AIS (Annual Information Statement)?

  • Full financial activity report
  • Includes:
    • TDS/TCS
    • Interest income
    • Mutual fund transactions
    • Stock trades
    • Property deals
    • Credit card spends
    • Foreign remittances

Best used to detect missing or misreported income.


3. What Is TIS (Taxpayer Information Summary)?

  • Auto-summarized version of AIS
  • Shows total reported income category-wise
  • Quick snapshot used by Income Tax Dept to flag returns
  • If your ITR doesn’t match this, you may get a notice
