Form 26AS vs AIS: What's the Difference (2026 Guide)
Two documents on the income tax portal are meant to help you file an accurate return, yet plenty of taxpayers only ever check one of them — and miss income the department already knows about. Here's a clear breakdown of Form 26AS vs AIS, what each actually contains, and why relying on just one can cause your ITR to be flagged.
What Is Form 26AS?
Form 26AS is your consolidated tax credit statement. It is generated from the TRACES portal and shows, against your PAN, all tax already deposited on your behalf during the year:
- TDS deducted by employers, banks, tenants, or clients
- TCS collected on specified transactions
- Advance tax and self-assessment tax you've paid directly
- Details of any tax refund issued to you during the year
- Information on certain specified high-value transactions (in a limited form)
In short, Form 26AS answers one question: how much tax has already reached the government on my behalf?
What Is AIS (Annual Information Statement)?
AIS is a much broader financial profile of your year, built from data reported by banks, registrars, mutual funds, stock exchanges, employers, and other entities. Along with everything in Form 26AS, AIS also includes:
- Savings and fixed deposit interest earned
- Dividend income from shares and mutual funds
- Purchase and sale of securities and mutual fund units
- Sale/purchase of immovable property
- Foreign remittances (under LRS) and certain foreign travel/credit card spends
- Off-market share transfers and other high-value transactions reported to the department
AIS effectively answers: what does the income tax department already know about my income and financial activity this year?
Form 26AS vs AIS — Side by Side
| Aspect | Form 26AS | AIS |
|---|---|---|
| Primary focus | Tax already paid/deducted | Full financial activity & income |
| Scope | Narrow — tax credit only | Broad — income, investments, transactions |
| Source system | TRACES | Income tax e-filing portal, AIS module |
| Correction mechanism | Via deductor's TDS return correction | Built-in online feedback option |
| Best used for | Claiming correct TDS/TCS credit | Ensuring all income sources are reported |
Where Does TIS Fit In?
The Taxpayer Information Summary (TIS) sits alongside AIS on the portal. It is a simplified, category-wise summary — derived from AIS but deduplicated and consolidated into clean totals (e.g., one figure for "interest income" instead of a dozen individual entries). TIS is what typically gets used to pre-fill your ITR, so it's worth a quick check even if you've already reviewed the detailed AIS.
Why You Must Check Both Before Filing
Filing based on Form 26AS alone can mean under-reporting income that the department already has on record through AIS — savings interest and dividend income are the most commonly missed items. On the other hand, checking only AIS without reconciling Form 26AS can mean claiming the wrong TDS credit or missing a credit that should be there. Reviewing both, side by side with your own salary slips, bank statements, and broker statements, is the safest way to file a return that won't attract a mismatch notice later.
How to Download Form 26AS and AIS
- Log in to the income tax e-filing portal at incometax.gov.in with your PAN.
- For Form 26AS: go to e-File → Income Tax Returns → View Form 26AS, which redirects to the TRACES portal; select the assessment year and download as PDF.
- For AIS: go to Services → Annual Information Statement (AIS), select the relevant financial year, and open either the AIS or TIS tab. Both can be downloaded as PDF/JSON.
What to Do If There's a Mismatch
If an entry in AIS looks wrong, duplicated, or doesn't belong to you, don't ignore it and don't just leave it out of your return either — use the "Optional Feedback" option against that specific entry in AIS, choosing the reason that applies (e.g., "income is not taxable," "duplicate entry," "information is incorrect"). This creates a record that you've reviewed and responded to the entry, which is useful if the department later questions the difference between AIS and your filed return. For Form 26AS discrepancies (like TDS not reflecting), the fix has to come from the deductor correcting their TDS return — flag it with them directly.

What is the main difference between Form 26AS and AIS?
Form 26AS is mainly a tax credit statement showing TDS, TCS, advance tax and self-assessment tax against your PAN. AIS (Annual Information Statement) is far broader, covering interest, dividends, securities and mutual fund transactions, foreign remittances, property transactions, and other high-value financial activity.
Should I file my ITR based on Form 26AS or AIS?
Check both before filing. Use Form 26AS to verify tax already paid or deducted, and use AIS to make sure you have reported all income sources it lists. Where the two conflict, investigate the source document (bank statement, broker statement) rather than blindly picking one.
What should I do if AIS shows incorrect information?
Use the built-in feedback option in AIS on the income tax portal to flag the specific entry as incorrect, duplicate, or not belonging to you, and select the appropriate reason. The reporting entity's data is not changed on the spot, but your feedback is recorded and reflected alongside the original entry.
