Quick answer. Log in at the income tax e-filing portal (incometax.gov.in). Open AIS to see all your reported income and transactions, read the TIS summary it builds, and open Form 26AS on TRACES for your TDS and TCS. Match all three with your own records before you file. Viewing them is free.
Most filing mistakes start with a number you never checked. Before you touch your return, three statements decide whether the tax department's view of your year matches your own. This guide defines each one in plain words, then walks you through reading them in order.
Your tax credit statement. From assessment year 2023-24 onwards, Form 26AS on the TRACES portal shows only your TDS (tax deducted at source) and TCS (tax collected at source) data. Think of it as the receipt for tax that someone else already deducted and deposited against your PAN.
Your full transaction file. AIS is the wide picture: salary, interest, dividends, share and mutual fund transactions, tax payments, refunds, foreign remittances, GST data and more. It is split into Part A (your general details, like PAN, masked Aadhaar, name and address) and Part B (the actual TDS/TCS information, SFT information from reporting entities, payment of taxes, demand and refund, and other information). AIS is where you give feedback when something is wrong.
The short version that fills your form. TIS is a category-wise rolled-up summary built from AIS. For each head it shows a processed value and a derived value. The derived value, after you accept or correct AIS entries, is what prefills your income tax return. Read TIS first to see the headline numbers, then dig into AIS for the line items behind them.
So the short rule: 26AS is your tax credit, AIS is your transaction story, TIS is the summary that lands in your return.
Log in at incometax.gov.in with your PAN or Aadhaar and password. From the dashboard, open the AIS menu (or go through Services then Annual Information Statement). Two tiles appear: TIS and AIS. Open TIS first for the summary, then AIS for the detail. You can download AIS in PDF, JSON or CSV. The PDF opens with a password: your PAN in lowercase followed by your date of birth in DDMMYYYY format, with no spaces.
From the same portal, go to e-File, then Income Tax Returns, then View Form 26AS. You will be sent to the TRACES portal; confirm the redirection, agree to the terms, then pick your assessment year. For income earned in financial year 2025-26 you select assessment year 2026-27. Choose HTML to view on screen or download a copy. Check that every TDS entry matches the Form 16 or Form 16A your deductor gave you.
Lay the three side by side. Does the salary in TIS match your payslips and Form 16? Does interest match your bank and post office statements? Does each TDS line in 26AS appear in AIS too? If your figures, AIS and 26AS all agree, the prefilled return is safe to use. If anything is off, fix it before you file, never after.
In AIS, click the line that is wrong, then the Optional button in the Feedback column, and pick the option that fits:
Submit it. AIS then shows your modified value beside the reported value, and the corrected figure flows into TIS, which prefills your return.
The Income Tax Department offers a free app, AIS for Taxpayer, on Google Play and the App Store. It shows the same AIS and TIS information and lets you submit feedback, which is handy when you only have a mobile to hand.
Figure: step-by-step flow. If a step stalls, use the grievance or RTI route shown.
Feedback tells the department you disagree, but the figure changes for good only when the reporting entity (your bank, employer or registrar) revises what it filed. If you have submitted feedback and the entry is still wrong after a reasonable wait, raise a grievance through the e-filing portal's grievance (e-Nivaran) module, quoting the AIS information ID. If a public authority holds a record you genuinely cannot get any other way, you can file an RTI or complaint route, though for most AIS mismatches the feedback and grievance path is faster.
Once your statements are clean, you are ready for the rest of the filing chain: confirm the figures, then file your ITR online, e-verify it, and later track your refund. If a deductor's TDS is missing from 26AS, your Form 16 is the proof you raise it with.
Because its job shrank. From assessment year 2023-24, Form 26AS carries only TDS and TCS data. Everything else, like high-value purchases, interest and SFT entries, moved to AIS. You did not lose anything; it is just in a different statement now.
Trust neither blindly; trust your own records. For a tax credit, 26AS is the deciding statement because that is the tax actually deposited against your PAN. For income figures, AIS and TIS lead. Where they clash, use AIS feedback to flag it.
Your PAN in lowercase followed by your date of birth (or date of incorporation) in DDMMYYYY, with no spaces or gaps. So PAN AAAAA1234A with a birth date of 28 July 1997 gives aaaaa1234a28071997.
Feedback records your disagreement, but the source value updates only when the reporting entity revises its filing. If it stays wrong, raise an e-Nivaran grievance on the portal with the information ID. Keep your own bank or salary proof ready.
You can, but it is risky. The department reconciles your return against AIS automatically, and a gap can trigger a notice. Reading AIS and TIS first is the simplest way to avoid one. If a notice does arrive, see our guide on how to reply to an income tax notice.
No. Viewing and downloading both Form 26AS and AIS through the income tax e-filing portal is free. If any site asks you to pay to see your own statement, it is not the official portal.
No. You can correct it by filing a revised or belated return within the allowed window. See our guide on revised and belated ITR for the current timelines and steps.
