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- Certain high-value transactions (a legacy feature, largely superseded by AIS now)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
AIS also has a 'TIS' (Taxpayer Information Summary) — a simplified, category-wise aggregated view derived from AIS, intended to make it easier to see the 'processed value' the department will likely consider for each income category when pre-filling your ITR.
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 |
| Where to access | e-filing portal > 'View Form 26AS' (redirects to TRACES) | e-filing portal > 'AIS' under 'Services' |
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
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.
