AIS vs Form 26AS 2026: Complete Guide to Checking, Matching & Filing ITR Correctly
In twenty years of practice, the most preventable notice I see is the one that arrives because a taxpayer filed their ITR based only on Form 16 and Form 26AS — and missed the FD interest, dividend, or mutual fund redemption sitting in their AIS. The department’s system compares your ITR against AIS automatically. When they do not match, Section 143(1)(a) generates an intimation without human intervention. No one reviews it, no one gives you a warning — the mismatch simply becomes a demand.
The fix is straightforward: check AIS before filing. Understand what is in it, what belongs there, what does not, and how to respond when something is wrong. This guide covers the complete picture — AIS structure, how it differs from Form 26AS, every entry type, the feedback process, five real scenarios, and the two-check annual habit that keeps notices away.
What Is AIS — Annual Information Statement
AIS (Annual Information Statement) was launched in November 2021 as the Income Tax Department’s comprehensive financial intelligence tool. It aggregates data from over 40 reporting entities — banks, employers, brokers, mutual fund RTAs, property registrars, credit card companies, GSTN, foreign remittance reporters, and from April 2026, crypto/VDA exchanges — all linked to your PAN.
The legal basis for SFT reporting under ITA 1961 was Section 285BA. Under the Income Tax Act 2025 (effective April 1, 2026), this moves to Section 508 — the obligation and thresholds remain broadly the same. The data flows from these reporters into AIS in near real-time, giving the department a complete picture of your financial activity that is often more detailed than what you remember yourself.
| AIS Category | What It Shows | Who Reports |
|---|---|---|
| Salary Income | Total salary + TDS deducted | Employer (TDS return) |
| Savings Account Interest | All bank accounts — annual interest | Banks (SFT) |
| Fixed Deposit Interest | FD/RD interest credited (even pre-maturity) | Banks (SFT) |
| Dividend | Share/MF dividends received | Companies and RTAs |
| Share Transactions | Buy/sell of listed shares — value | Stock exchanges (SFT) |
| Mutual Fund Transactions | Purchase and redemption — amounts | RTAs — CAMS, KFintech (SFT) |
| Property Sale/Purchase | Stamp duty value and transaction value | Sub-Registrar (SFT) |
| Cash Deposits | ₹10L+ savings / ₹50L+ current account | Banks (SFT) |
| Credit Card Payments | ₹10L+ annual spend / ₹1L+ single cash payment | Banks/card companies (SFT) |
| Foreign Remittances (LRS) | ₹7L+ sent or received abroad | Authorised dealer banks (SFT) |
| GST Turnover | Business turnover from GSTN filings | GSTN |
| TCS Collected | Tax collected on car, tour packages, forex | TCS collectors |
| Advance Tax Paid | Quarterly advance tax challans | Banks |
| Crypto / VDA Transactions | All buy/sell on registered exchanges | Crypto exchanges — from April 2026 |
What Is Form 26AS
Form 26AS is the older “Tax Credit Statement” — introduced in 2003, still essential for one specific purpose: verifying TDS credit. Every rupee of TDS deducted against your PAN by any deductor should appear in Form 26AS. This is what the department’s system uses to credit TDS against your tax liability at ITR processing time.
| Part | Contents |
|---|---|
| Part A | TDS on salary, interest, commission, professional fees — by deductor and quarter |
| Part B | TCS — tax collected at source on car purchase, LRS, overseas tour, etc. |
| Part C | Advance tax and self-assessment tax paid — challan details |
| Part D | Tax refunds received in prior years |
| Part F | TDS on property purchase — Form 26QB entries |
| Part G | TDS on rent — Form 26QC entries (194IB) |
Since 2023, Form 26AS has been progressively simplified — detailed financial transaction data has shifted to AIS. Form 26AS now functions primarily as the TDS ledger. Always verify TDS amounts from Form 26AS before claiming them in your ITR — only TDS reflected in Form 26AS can be claimed as credit.
AIS vs Form 26AS — Side-by-Side Comparison
| Parameter | AIS | Form 26AS |
|---|---|---|
| Launched | November 2021 | 2003 |
| What it covers | All financial transactions — income + assets + tax | TDS, TCS, advance tax, refunds |
| Number of data sources | 40+ entities including GSTN, exchanges, registrars | TDS deductors and TCS collectors |
| Update frequency | Near real-time | After quarterly TDS return filing |
| Income coverage | Salary, interest, MF, shares, property, credit card, forex, crypto | Income where TDS was deducted — not all income |
| Can it be corrected? | Yes — online feedback mechanism | Only if deductor files revised TDS return |
| Primary use for ITR | Reconcile all income before filing | Verify TDS credit amounts |
| Which is more important? | AIS — comprehensive income picture | Form 26AS — still critical for TDS credit |

How to Download AIS — Step by Step
- Login at incometax.gov.in using your PAN and password. If not registered — register with PAN and Aadhaar (takes 5 minutes).
- Navigate: Dashboard → Services → Annual Information Statement (AIS). A new tab opens — the AIS portal.
- Select Assessment Year: For FY 2025-26 → select AY 2026-27. Two views available: AIS (full detail) and TIS (Taxpayer Information Summary — aggregated totals only).
- Download: Click “Download” → choose PDF or JSON. The PDF is password protected — password = PAN in capitals + date of birth in DDMMYYYY format. Example: ABCDE1234F01041985.
- Review: Open every section — Salary, Other Income (TDS), Savings Interest, FD Interest, Dividends, MF Transactions, Share Transactions, Property, Cash Deposits. Compare each entry against your own records.
Types of AIS Entries and What to Do with Each
| Entry Type | What It Means | Action Required |
|---|---|---|
| Salary — matches Form 16 | Employer TDS return filed correctly | Declare in ITR — no action needed |
| FD Interest — amount correct | Bank reported accurately | Declare under Schedule OS — claim TDS credit if any |
| FD Interest — amount overstated | Bank reported wrong amount or wrong PAN | AIS feedback → “Information is not fully correct” with bank statement |
| MF Redemption value | RTA reported full sale value — not the gain | Declare capital gain (sale value − cost) in Schedule CG — not the full redemption amount as income |
| Property sale | Sub-registrar reported stamp duty value | Declare capital gain in Schedule CG. Buyer’s TDS (Form 26QB) appears separately in Form 26AS. |
| Cash deposit — high value | Bank reported SFT | Ensure source of funds is documented and income is declared. No separate ITR entry — but cross-check that corresponding income is in your return. |
| Transaction of another person | Wrong PAN linkage in reporter’s records | AIS feedback → “Information relates to other PAN/year” with supporting documentation |
| Duplicate entry | Same transaction reported twice | AIS feedback → “Duplicate information” |
| Crypto/VDA transaction | Exchange filed SFT from April 2026 | Declare gain/loss in Schedule VDA — 30% flat rate regardless of holding period |
| GST turnover | GSTN data — business income indicator | Ensure ITR business income (Schedule PGBP) is consistent with GST turnover — reconcile any difference |
AIS Feedback Process — Correcting Wrong Entries
When an AIS entry is incorrect — wrong amount, wrong PAN, duplicate — you can submit feedback directly through the AIS portal. This does not immediately change the source data, but it creates a modified value that you can use in your ITR and that the department sees alongside the original reported value.
- Open AIS portal → navigate to the specific entry
- Click “Feedback” next to the entry
- Choose one of: Information is correct / Information is not fully correct (enter correct amount) / Information relates to other person or year / Information is duplicate / Information is denied (transaction never happened)
- Attach supporting document — bank statement, broker statement, property document as applicable
- Submit → AIS now shows both “Reported Value” (original) and “Modified Value” (your feedback)
- Use the Modified Value in your ITR if the correction is genuine
Five Real Scenarios
Scenario 1 — FD Interest Missed: ₹2 Lakh Notice Avoided
Mr. Verma, Delhi, salary ₹12 lakh. He checked only Form 26AS before filing — it showed employer TDS of ₹85,000. Salary declared. ITR filed. Three months later, a Section 143(1)(a) intimation arrived: AIS showed FD interest ₹2 lakh from two banks, MF dividend ₹18,000, and savings interest ₹12,000 — none of which he had declared. Total additional income: ₹2.3 lakh. Tax demand: ₹46,000 plus interest.
He had checked Form 26AS — which only showed TDS. He had not checked AIS — which showed the income. A revised ITR could have been filed for free before December 31. After the intimation, the demand had to be paid with 234B interest.
Prevention: One AIS download in April. Everything in Schedule OS. No notice.
Scenario 2 — MF Redemption: Understand What AIS Shows
Rohit redeemed a mutual fund worth ₹8 lakh — his original investment was ₹6 lakh, so the gain was ₹2 lakh. AIS showed “Mutual Fund Redemption: ₹8,00,000.” He panicked — “Do I declare ₹8 lakh as income?” No. The ₹8 lakh is the redemption proceeds. The income is the capital gain: ₹2 lakh. He declared ₹2 lakh LTCG in Schedule CG. The AIS entry of ₹8 lakh was the full transaction value — the ITR declared the gain correctly. No mismatch, no notice.
Key understanding: AIS shows transaction values for shares and MFs — not the taxable gain. Declare the gain in Schedule CG, not the full redemption amount.
Scenario 3 — Wrong PAN Entry: ₹50 Lakh Property Transaction
Suresh found a ₹50 lakh property purchase entry in his AIS — a transaction he had never made. The sub-registrar had recorded a wrong PAN at property registration. Suresh submitted AIS feedback: “Information relates to other person” — attached his own PAN card and a statement that he had not purchased any property in FY 2024-25. The Modified Value was updated. He filed his ITR without the property entry. No notice was generated.
Without AIS feedback, the ₹50 lakh entry would have appeared as an unexplained high-value transaction against his PAN — certain to generate a scrutiny notice.
Scenario 4 — Credit Card Spend vs Income: Source of Funds Query
Priya, declared salary ₹10 lakh, had credit card spending of ₹14 lakh in AIS. The department sent a notice asking her to explain the source of funds for the spending that exceeded her declared income. She documented: ₹3 lakh was her husband’s expenses on her card (he is an authorised user), ₹1 lakh was business reimbursements credited separately. She submitted the explanation via e-Proceedings with bank statements and card statements. The case was closed.
Checking AIS in April would have told her this entry was there — she could have prepared the explanation before the notice, not scramble after it arrived.
Scenario 5 — GST Turnover vs ITR Gap: Business Income Notice
Kavya, a freelance designer, had GST turnover of ₹28 lakh in GSTR-1 for FY 2024-25. Her ITR under Section 44ADA (50% presumptive) declared business income of ₹12 lakh (50% of ₹24 lakh). The gap: ₹4 lakh in GST invoices raised in March were paid in April and included in GST but excluded from ITR (timing difference). AIS showed GST turnover ₹28 lakh — ITR showed ₹24 lakh. Scrutiny notice arrived asking for reconciliation.
She provided the March invoice list, payment dates (April receipts), and GSTR-1 vs bank statement reconciliation. The AO accepted the timing explanation. But the exercise took 3 months of back-and-forth. A one-page GST-to-ITR reconciliation prepared before filing would have prevented it entirely.

The Two-Check Annual Habit
Check 1 — April/May: Before Filing
Download AIS in April. Review every category. Cross-check each entry against your own records — bank interest certificates, broker P&L statements, MF account statements, salary slips. For any entry that is incorrect — submit AIS feedback with supporting documents. For any income you find that you had forgotten — add it to your ITR. File your ITR with a complete, reconciled income picture.
Check 2 — October: After Filing
Download AIS again in October — three months after the July 31 ITR deadline. Why? Several reporting entities file SFT late — after the ITR deadline. Bank branches that missed the Q1 deadline, brokers that corrected transaction data, MF RTAs that updated dividend records — all of this can appear in AIS after you have filed. If something new has appeared that was not in your filed ITR — December 31 is still the revised ITR window. Correct it proactively. Do not wait for the notice that arrives when the department does its own AIS-ITR comparison.
April check → file complete ITR → no July-onwards mismatch notices.
October check → file revised ITR if needed → no January-onwards demand notices.
Both together — and maintained annually — eliminate the most common source of income tax notices for salaried and small-business taxpayers.
When AIS and Form 26AS Conflict
| Conflict Type | What It Means | What to Do |
|---|---|---|
| AIS shows TDS but Form 26AS does not | Employer/deductor reported in SFT but TDS return not yet filed or filed late | Wait for Form 26AS to update (5–15 days after deductor files) before claiming TDS credit |
| Form 26AS shows TDS but AIS income entry is missing | TDS return filed but SFT income data not yet in AIS | Declare income based on actual records — AIS may update later; income declaration does not depend on AIS |
| AIS income amount ≠ your actual records | Reporting entity gave wrong data | Submit AIS feedback with documentation |
| TDS in Form 26AS ≠ Form 16/16A issued by deductor | Deductor cut TDS but deposited wrong amount or under wrong PAN | Contact deductor to file revised TDS return; claim only what Form 26AS shows |
Frequently Asked Questions
Q1. Which is more important — AIS or Form 26AS?
They serve different purposes and both are essential. AIS is more comprehensive for income verification — it shows everything the department knows about your finances. Form 26AS is still the authoritative source for TDS credit claims. Use AIS to build your complete income picture; use Form 26AS to verify TDS amounts before claiming them in your ITR.
Q2. AIS shows my FD interest as ₹85,000 but I only received ₹60,000 in the current year. The rest will come at maturity next year. What do I do?
FD interest is taxable on accrual basis — the bank reports it as it accrues, not when you receive it at maturity. If ₹85,000 accrued in FY 2025-26 — you declare ₹85,000 in your FY 2025-26 ITR, regardless of whether the FD has matured. Submit AIS feedback only if the bank’s reported figure differs from what your FD interest certificate shows.
Q3. AIS shows my mutual fund redemption as ₹4.2 lakh. Do I declare ₹4.2 lakh as income?
No. ₹4.2 lakh is the redemption proceeds — the full sale value. Your taxable income is the capital gain: sale value minus cost of acquisition. Compute the gain from your MF statement or broker records and declare it in Schedule CG. The AIS entry confirms the transaction happened — it does not define the taxable amount.
Q4. I submitted AIS feedback two weeks ago but the entry still shows the original amount. Can I use my corrected amount in ITR?
Yes. AIS shows both “Reported Value” (original) and “Modified Value” (your feedback). If your feedback has been submitted and shows as “Modified,” use the Modified Value in your ITR. Attach the AIS feedback acknowledgement as documentation. If the feedback has not yet been processed, file with your documented correct amount and a note that feedback was submitted — keep the submission acknowledgement.
Q5. I have crypto transactions in FY 2025-26 — will they appear in AIS?
For FY 2025-26 (Tax Year 2025-26 under ITA 1961) — crypto exchange SFT reporting was not yet mandatory for all exchanges. From April 2026 (Tax Year 2026-27 under ITA 2025) — registered exchanges must file SFT for all VDA transactions. Regardless of whether your FY 2025-26 crypto transactions appear in AIS — you are required to declare all VDA gains in Schedule VDA at 30% flat rate. The department has other ways to know about crypto transactions even without SFT.
Q6. My AIS shows a property sale of ₹45 lakh — I sold my flat. Do I need to declare ₹45 lakh as income?
No. The property sale itself is not income. The capital gain — sale value minus indexed cost (or unindexed at 12.5% for post-July 2024 sales) — is income. Declare the gain in Schedule CG. The ₹45 lakh AIS entry confirms the transaction; the ITR Schedule CG shows the taxable profit. Also check Form 26AS — the buyer should have deposited 1% TDS (Section 194IA) if sale value exceeded ₹50 lakh; claim that TDS credit.
Q7. I received a 143(1)(a) intimation for AIS-ITR mismatch. What do I do?
First, review the specific mismatch the intimation identifies. If the income was genuinely missed — pay the tax and file a revised ITR (if within December 31 window) or pay via Challan 280 and respond via e-Proceedings. If the AIS entry was incorrect — respond via e-Proceedings with documentation proving the AIS entry is wrong (the AIS feedback you should have submitted before filing). Never ignore an intimation — even a nil response confirms receipt and prevents escalation.

Q8. AIS PDF password — I keep forgetting it.
Password = PAN (in capital letters) + Date of Birth (in DDMMYYYY format). Example: PAN ABCDE1234F, DOB April 1, 1985 → password is ABCDE1234F01041985. No spaces, no separators. The JSON format download does not require a password — it is readable by any JSON viewer or text editor.
Q9. My employer’s salary in AIS differs from my Form 16. Which is correct?
Investigate the difference before assuming either is wrong. Common reasons: AIS includes perquisites (car perk, accommodation perk) that Form 16 may have listed separately; AIS includes notice pay from a previous employer that you may have overlooked; AIS includes salary from a previous employer in the same year that was not included in your current Form 16. If after investigation a genuine data error exists — contact your employer to file a revised TDS return, which updates Form 26AS and consequently AIS.
Conclusion
AIS is not optional background reading before filing — it is the document the department uses to verify your ITR. Every entry in AIS that belongs to you must appear in your ITR. Every entry that does not belong to you must be corrected via feedback. The two checks — April before filing, October after filing — close the gap between what the department sees and what your ITR declares, and in doing so, eliminate the most common category of income tax notices for individual taxpayers.
Mr. Verma’s ₹46,000 demand came from not checking AIS before filing. Rohit’s correct ITR came from understanding that MF redemption value ≠ taxable income. Suresh’s ₹50 lakh wrong entry was resolved in 15 days because he submitted feedback with documentation. Each case had the same underlying lesson: AIS check early, act on what you find, and file complete.
