AIS / 26AS — quick answers

Why does a mismatch trigger a notice?

The department auto-compares your filed ITR with AIS/26AS. If AIS shows income you didn't report (or you claim TDS not in 26AS), the system flags it for an automated intimation u/s 143(1) or a scrutiny notice. Reconciling first is the safest fix.

AIS and 26AS differ — which do I trust?

Use 26AS as the authoritative source for TDS/TCS credits and AIS for income completeness. If AIS over-reports (e.g. a sold-and-rebought share counted twice, or someone else's PAN), submit AIS feedback — don't just ignore it.

I found a real mismatch. Now what?

Report the correct income in your ITR, claim only the TDS in 26AS, and submit AIS feedback for genuine AIS errors. Complex case (capital gains, multiple Form 16s, foreign income)? Let our experts reconcile & file it →
