AIS vs TIS vs Form 26AS: Meaning, Difference & Mismatch Fixes
Form 26AS = your TDS/TCS credit. AIS = the department's full dossier on you. TIS = its summary that pre-fills your ITR. Check all three before filing — mismatches cause most notices.
The difference in one table
| Form 26AS (→ Form 168) | AIS | TIS | |
|---|---|---|---|
| Shows | TDS/TCS, advance & self-assessment tax, refunds | Everything: salary, interest, dividends, securities, MF, property, remittances, GST turnover, SFT data | Category-wise totals (processed + derived values) |
| Where | TRACES (via e-File → View 26AS) | e-filing portal → AIS menu, or AIS for Taxpayer app | |
| Feedback? | No (ask deductor to correct) | Yes — structured feedback options | Auto-updates after AIS feedback |
| Use in ITR | Claim TDS credit | Verify you declared all income | Source of pre-filled figures |
How to download AIS (2 minutes)
- Log in at incometax.gov.in → AIS on the dashboard (or e-File → AIS) → Proceed.
- Open the AIS tile for details, TIS tile for the summary. Download PDF/CSV/JSON.
- Compare every head with your records — salary, savings interest, FD interest, dividends, share/MF transactions.
- Wrong entry? Submit online feedback (e.g. not-my-transaction, duplicate) — TIS derived value updates.
Mismatch = notice. Fix first, file after.
Lakhs of notices every year trace to one cause: the ITR omits income visible in AIS (often small interest or a forgotten MF redemption). The fix order: (1) reconcile AIS with bank statements, (2) give feedback on genuinely wrong entries, (3) declare everything genuine. Already filed with a gap?
