What is an AIS / Form 26AS mismatch?
It's when the income or TDS in your return doesn't match the tax department's own records (the AIS and Form 26AS). A mismatch is the most common reason for an automated Section 143(1)(a) adjustment.
How do I check for a mismatch before filing?
Log in at incometax.gov.in, download your AIS and Form 26AS, and compare each figure — interest, dividends, salary TDS, capital gains — against what you're about to report.
What's the most common AIS mismatch?
Forgotten FD and savings interest, and dividends — banks report these even though TDS was deducted, so leaving them out of your return creates a gap.
What if my AIS shows something that's wrong?
You can submit feedback on the specific entry in the AIS portal and report the correct figure in your return — keep proof in case of a later query.
