AIS vs Form 26AS: What's the Difference & Which Should You Check Before Filing?

Reviewed by CA Nikhil Gupta · Last reviewed 17 June 2026

Before you file your ITR, you should check two documents on the income tax portal — Form 26AS and AIS (Annual Information Statement). They overlap but aren't identical: AIS is far more comprehensive, covering everything from your savings account interest to mutual fund redemptions and foreign remittances, while Form 26AS focuses mainly on tax deducted/collected and a few other items. Mismatches between what you report and what AIS shows are now one of the leading causes of tax notices.

What Is Form 26AS?

Form 26AS is a consolidated tax credit statement showing:

TDS (Tax Deducted at Source) on your income — salary, interest, professional fees, rent, etc.
TCS (Tax Collected at Source)
Advance tax and self-assessment tax paid by you
Refunds issued during the year
Certain high-value transactions (a legacy feature, largely superseded by AIS now)

What Is AIS (Annual Information Statement)?

AIS is a much broader statement introduced to give taxpayers a comprehensive view of the financial information the tax department has about them, including:

All Form 26AS information (TDS/TCS, tax payments, refunds)
Savings account interest, FD interest, dividend income
Securities transactions — purchase/sale of shares, mutual funds
Off-market transactions, mutual fund purchases/redemptions/SIPs
Foreign remittances under LRS
Sale/purchase of immovable property
GST turnover (for business taxpayers)
Interest on income tax refund

Key Differences at a Glance

Feature	Form 26AS	AIS
Scope	Mainly TDS/TCS, tax payments, refunds	Much broader — includes interest, dividends, securities, property, foreign remittances, GST turnover
Used for ITR pre-fill	Yes (TDS/TCS data)	Yes (broader categories)
Feedback mechanism	No	Yes — you can flag information as incorrect/duplicate/not relating to you

Why Do AIS and Form 26AS Sometimes Not Match?

Because AIS aggregates data from many more sources (banks, registrars, mutual fund RTAs, stock exchanges, etc.) and is updated more frequently, it often shows information that Form 26AS doesn't — and vice versa, since Form 26AS reflects only what's been formally reported through TDS/TCS returns by deductors. A mismatch doesn't automatically mean an error; it could simply mean the AIS source hasn't yet been reflected in Form 26AS, or the reverse.

⚠ Use the AIS feedback option: If AIS shows a transaction that's incorrect, a duplicate, or doesn't belong to you (a common issue with PAN mismatches on securities transactions), submit feedback directly on the AIS portal. This feedback is recorded and considered, and helps avoid future notices based on that incorrect entry — though it doesn't retroactively change the source document.

Which Should You Rely On When Filing?

Best practice: cross-check both. Use Form 26AS to verify TDS/TCS credits you're claiming match what's been deposited against your PAN. Use AIS to ensure you haven't missed reporting any income (especially interest, dividends, and capital gains from securities) that the department already has on record — since a mismatch here is the most common trigger for a Section 143(1) adjustment or a subsequent notice.

Practical Checklist Before Filing

Download both Form 26AS and AIS/TIS from the e-filing portal
Tally TDS/TCS entries in Form 26AS against your Form 16/16A and bank certificates
Go through AIS category by category — interest, dividends, securities transactions, property transactions — and ensure each is reflected in your ITR (either as taxable income or with the correct exemption claimed)
For any incorrect AIS entries, submit feedback through the portal
Only then proceed to file your ITR

2026 Accuracy & Decision Check

AY 2026-27 reconciliation: AIS is broader than Form 26AS

For recent assessment years, Form 26AS is primarily the tax-credit/withholding statement, while AIS is the broader information statement covering reported financial transactions, interest, dividends, securities and other third-party data with a feedback mechanism. Neither should be copied mechanically into the return: reconcile both to books/bank/broker records and correct the source record where information is wrong.

Decision / evidence controls

Match TDS/TCS/challan credits to Form 26AS and the return tax-credit schedule.
Use AIS/TIS to identify income/transactions that may not appear in Form 26AS.
Submit AIS feedback where a third-party report is incorrect or duplicated.
Keep evidence of feedback and the final return position for scrutiny.

Worked example: Example: bank interest can appear in AIS even where no TDS was deducted and therefore no corresponding Form 26AS TDS line exists; it can still be taxable income.

Edge case: Edge case: a wrong AIS entry should not be blindly included merely to “match the portal”; report the legally correct return and use the feedback/correction workflow with evidence.

Frequently Asked Questions

If AIS shows income I've already reported correctly, do I need to do anything? ▼

No. If you've already correctly included that income in your ITR computation, no further action is needed for that entry — it's simply confirming the department's record matches your filing. The main risk is when AIS shows income (like savings account interest, dividend income, or mutual fund capital gains) that you have NOT included in your return — that's the kind of mismatch that commonly triggers a Section 143(1) adjustment or a follow-up notice.

AIS shows a securities transaction that isn't mine — what should I do? ▼

Use the feedback mechanism available directly on the AIS portal (accessible via the e-filing portal under 'Services > AIS'). You can mark the specific entry as 'Information is not fully correct', 'Information relates to other PAN/year', or 'Information is duplicate/included in other information', among other options. This feedback is recorded by the department and is taken into account, though it doesn't retroactively correct the underlying source document filed by the reporting entity (e.g., a broker or registrar) — for that, you may also need to contact the reporting entity directly to correct their filing.

Is Form 26AS being phased out in favor of AIS? ▼

Form 26AS continues to be relevant primarily for verifying TDS/TCS credits and tax payments against your PAN, and is still accessible via the e-filing portal (which links to the TRACES system). However, AIS has become the more comprehensive document for understanding the full range of financial information the tax department holds about you — including income types Form 26AS doesn't cover, like savings interest, dividends, and securities transactions. Best practice is to check both before filing, since they serve overlapping but not identical purposes.
