IT filing 2026: Your AIS might have an error; here's how to spot it, fix it, and track it with one PDF
1/9
There's a document that knows more than you think
Before you file your income tax return, there's one document worth checking first: the Annual Information Statement, or AIS. It's a complete snapshot of your financial year, built to help you file accurately and avoid surprises later.
2/9
What exactly is AIS?
AIS is a comprehensive statement that shows the tax department everything it knows about your finances for the year, from salary and interest to high-value transactions. It's designed to make filing easier by letting you cross-check your numbers before you submit your return.
3/9
It's also a compliance tool
AIS isn't just for your convenience. It helps the tax department promote voluntary compliance, enables smoother prefilling of returns, and makes it harder for mismatches or non-disclosures to slip through unnoticed.

Part A: The basics about you
The first section of AIS covers your personal details: PAN, masked Aadhaar number, name, date of birth or incorporation, mobile number, email, and address. Think of it as your identity snapshot within the statement.
5/9
Part B: Where the real financial data lives
This is the section that matters most for filing. It includes your TDS and TCS details, financial transactions reported by banks and institutions (SFT data), tax payments like advance tax and self-assessment tax, and any demand or refund activity for the year.

AIS vs Form 26AS: what's the difference?
Since AY 2023-24, Form 26AS only shows TDS and TCS data. Everything else, investments, high-value transactions, other income sources, now lives in AIS. If you're only checking Form 26AS, you're missing half the picture.

Spotted an error? You can fix it
Found something incorrect in your AIS? Log in to the Income Tax e-Filing Portal, go to Services, open AIS, click the flagged entry, and hit the Optional feedback button. Choose the reason, like "incorrect," "duplicate," or "belongs to another PAN" -and submit.

What happens after you submit feedback
Once you submit, your feedback appears alongside the original entry, along with a modified value. You'll get email and SMS confirmation, plus an Acknowledgement Receipt you can download for your records, so there's always a paper trail.
9/9
One more tool worth knowing: The consolidated feedback file
If you've submitted multiple corrections, the AIS Consolidated Feedback File (ACF) compiles all your feedback into a single downloadable PDF, making it easy to review everything you've flagged in one place before you file.
