Understanding AIS, TIS, and Form 26AS — What Each One Means

Before you can resolve AIS/TIS mismatch income tax notice, you need to understand what these three documents are and why they exist.

Form 26AS — The Tax Credit Statement

Form 26AS is the government’s official Annual Tax Statement. Think of it as your verified tax ledger. For AY 2026-27 (FY 2025-26), it primarily captures:

TDS deducted on your salary, interest, professional fees, rent, and property sale proceeds
TCS collected by sellers on high-value goods or foreign remittances
Advance tax and self-assessment tax payments made by you with challan details
Income Tax refunds credited in previous years

Important note: From FY 2026-27 onwards, Form 26AS is being renamed Form 168 under Income Tax Rules 2026. However, for ITR filing of FY 2025-26 (AY 2026-27, due July 31, 2026), Form 26AS remains the applicable document. The critical rule: TDS credits can only be claimed based on Form 26AS — not on AIS alone.

AIS — The Annual Information Statement

AIS is the broader, more comprehensive financial picture of your entire year. Introduced by CBDT in November 2021, the Annual Information Statement aggregates data from dozens of reporting entities — banks, employers, brokers, registrars, mutual fund houses, and even the GST network.

For AY 2026-27, AIS captures:

Salary income reported by your employer
Interest from savings accounts, FDs, RDs, and bonds
Dividends from listed and unlisted companies
Mutual fund purchase, redemption, and dividend transactions
Securities transactions and capital gains
Sale and purchase of immovable property above SFT thresholds
Foreign remittances under the Liberalised Remittance Scheme (LRS)
Cash deposits and withdrawals exceeding SFT thresholds
Credit card spending above reporting thresholds
GST turnover declared in GSTR-3B

TIS — The Taxpayer Information Summary

The TIS is a simplified, aggregated version of AIS. It groups individual transactions into category totals — for example, total FD interest earned, total dividend received, or total capital gain — and reflects any feedback you’ve submitted on AIS entries. Crucially, the TIS directly feeds into the ITR pre-fill data on Income tax portal. So when the portal auto-fills your salary or interest income, it’s pulling that data from TIS — which in turn comes from AIS.

Why You Received AIS/TIS Mismatch Income Tax Notice?

Receiving income tax notice AY 2026-27 due to AIS or TIS mismatch happens for one core reason: the figures in your filed ITR differ from what Income Tax Department sees in its system. The Department’s automated processing engine — which runs under Section 143(1) — compares your reported income against AIS/TIS data, and any gap triggers an alert.

Here are the most common root causes:

You reported less income than AIS shows If your employer reported higher salary figure to the department than what appeared on your Form 16, or if a bank reported more FD interest than you declared, the system will flag it as unreported income.

AIS itself contains errors AIS data is reported by third parties — banks, brokers, mutual fund houses. These reporting entities sometimes submit incorrect data: duplicate entries, transposed amounts, or transactions linked to a wrong PAN. However, the system doesn’t automatically know the data is wrong — it takes it at face value until you file feedback.

Capital gains not reported or under-reported Mutual fund redemptions, stock sales, and property transactions are now tracked in AIS with precision. If you sold shares or redeemed a mutual fund but didn’t report capital gains mismatch AIS income tax 2026 correctly, the system will compare and flag it.

FD interest missed Banks report all FD interest above ₹5,000 to the department through AIS. Many taxpayers miss this, especially interest on FDs held in multiple banks. The result is an FD interest AIS mismatch notice that arrives after ITR processing.

High-value transactions not explained Cash deposits above ₹10 lakh, credit card payments above ₹1 lakh (cash) or ₹10 lakh (total), or property purchases above ₹30 lakh are all reported under the SFT framework. These appear as high value transaction AIS notice situations when not reflected in your ITR.

TDS shown in AIS but not Form 26AS This happens when the deductor filed a TDS return but it hasn’t yet been processed on TRACES. If you claim TDS credit based on AIS (not Form 26AS), the system rejects it.

Most Common Types of AIS Mismatch Notices in AY 2026-27

Understanding the type of AIS mismatch income tax notice you’ve received helps you respond accurately and efficiently.

Salary Mismatch Notice

This is the most common type. Your employer reports gross salary to the department, but you may have declared a lower net figure after exemptions. Income tax notice salary mismatch AIS asks you to reconcile the difference.

FD / Savings Interest Mismatch

Banks report interest credited to your account. If you didn’t include all interest income — especially from multiple banks or joint accounts — AIS mismatch notice flags the gap.

Capital Gains Mismatch (Stocks, Mutual Funds, Property)

Brokers and depositories report all securities transactions to the department. If your ITR shows different capital gains figures, expect a capital gains mismatch AIS income tax 2026 notice, particularly for short-term transactions or unlisted shares.

Dividend Income Mismatch

Companies report dividend payments to AIS. If you missed reporting dividend income — even small amounts from multiple companies — it shows up as a mismatch.

High Value Transaction / SFT Notice

Unusually large cash deposits, property purchases, or credit card payments can generate high value transaction AIS notice if they don’t correlate with your declared income.

Section 143(1) Intimation

This is technically not a scrutiny notice, but rather an automated intimation after processing. It’s the most common follow-up after an AIS ITR mismatch income tax notice. It quantifies the additional tax demand based on the mismatch.

How to Respond to AIS Mismatch Notice

If you’ve already received income tax notice AY 2026-27, don’t panic. Income Tax Department provides a clear online mechanism to respond. Here’s exactly how to respond to AIS mismatch notice online in India:

Step 1: Log in to Income Tax Portal

Go to incometax.gov.in and log in using your PAN as the User ID.

Step 2: Navigate to the Notice/Pending Actions Section

From the dashboard, go to e-File → Pending Actions → Respond to Outstanding Demand (for Section 143(1) intimation) or e-Proceedings (for scrutiny notices).

Step 3: Open the Notice and Read Carefully

Click on the notice to understand exactly which income head is disputed and what figure the Department expects versus what you reported.

Step 4: Gather Your Evidence

Pull together the following based on the type of mismatch:

Salary mismatch → Form 16 from employer, salary slips
FD interest mismatch → Bank FD statements, TDS certificates (Form 16A)
Capital gains mismatch → Broker’s capital gains statement, demat account ledger
Property sale mismatch → Sale deed, stamp duty certificate, purchase cost documents
High-value transaction → Bank statements explaining the source/nature of transactions

Step 5: Submit AIS Feedback (If AIS Data is Wrong)

If the mismatch is because AIS contains incorrect data (not your reporting error), submit feedback on AIS portal:

Go to Services → Annual Information Statement (AIS)
Select the incorrect transaction
Click “Feedback” and choose the appropriate option: Information is not correct, Duplicate, Belongs to another person, etc.
Provide details and supporting documents

The reporting entity (e.g., bank) then gets 30 days to respond. Once they confirm or accept your feedback, the TIS updates automatically.

Step 6: File Revised ITR (If You Under-Reported Income)

If the Department’s data is correct and you genuinely missed income, file revised ITR under Section 139(5) before the deadline. Declare the correct income and pay any additional tax due along with applicable interest under Sections 234B and 234C.

Step 7: Respond Online with Explanation

In the e-Proceedings or Outstanding Demand section, select your response:

Agree → Pay the additional demand
Partially Agree → Pay for the agreed portion, explain the rest
Disagree → Upload your explanation and supporting documents

How to Fix AIS Mismatch Before or After Filing ITR

Prevention is far better than cure. Here’s how to fix AIS mismatch before ITR filing — and what to do if you’ve already filed.

Before Filing: The Pre-Filing Reconciliation Checklist

Step 1: Download all three documents Log in to incometax.gov.in and download Form 26AS, AIS (JSON or PDF), and TIS. Do this at least 1–2 weeks before you file.

Step 2: Cross-check salary figures Compare AIS salary data with your Form 16 Part A and Part B. Small differences are often due to employer timing or gross vs. net reporting.

Step 3: Reconcile all interest income Total up interest from all FDs, RDs, and savings accounts across all banks, and match it against AIS. Don’t forget joint accounts — 50% of the interest may be attributed to your PAN.

Step 4: Verify capital gains Match your broker’s capital gain statement with what AIS shows. Errors in buy cost, date, or quantity are common and need feedback correction before filing.

Step 5: Review TIS pre-fill values Check the TIS figures carefully before accepting the auto-filled ITR data. Never blindly accept pre-fill — always verify against actual documents.

Step 6: Submit AIS feedback for incorrect entries For any wrong data in AIS, submit feedback immediately. The TIS will update after feedback acceptance, giving you cleaner pre-fill values for your ITR.

After Filing: If Mismatch Notice Arrives

Respond within the notice deadline (typically 30 days)
File a revised ITR if income was genuinely missed
Submit AIS feedback with proof if AIS data is incorrect
Keep all documents (bank statements, Form 16, broker reports) ready

What Happens If You Ignore the Notice?

Ignoring AIS mismatch income tax notice is one of the costliest mistakes you can make. Here’s what the consequences look like:

Consequence	Detail
Additional Tax Demand	Under Section 143(1), the mismatch amount gets added to your taxable income and taxed at your slab rate
Interest Under Section 234A/B/C	Interest at 1% per month on the unpaid tax liability
Penalty Under Section 270A	Up to 200% of the under-reported tax for concealment or misreporting
Scrutiny Assessment	Repeated non-response can lead to a full scrutiny under Section 143(3)
Prosecution Risk	In extreme cases of deliberate concealment, prosecution under Section 276C

Therefore, responding promptly and honestly to any income tax notice AY 2026-27 is not just advisable — it’s critical.

Pro Tips to Avoid AIS/TIS Mismatch Notices in the Future

Moreover, once you’ve resolved your current notice, you’ll want to ensure this doesn’t happen again. Here are practical, expert-backed tips:

Download AIS every quarter, not just at tax time — monitor entries as they appear throughout the year
Link all your PAN-linked accounts — savings accounts, FDs, demat accounts, and mutual funds — and track them together
Don’t ignore small interest income — even ₹5,000 in FD interest gets reported to AIS and can trigger notices if omitted
Use AIS feedback mechanism proactively — if you spot wrong data, flag it immediately, don’t wait until filing season
Reconcile Form 26AS and AIS before claiming TDS — TDS credit must appear in Form 26AS (not just AIS) to be validly claimed
Report all capital gains accurately — use your broker’s official tax report, not manual calculations
Consult a tax professional for complex situations involving property sales, foreign income, ESOPs, or business income.

Conclusion

Receiving an AIS/TIS mismatch income tax notice for AY 2026-27 is stressful — but it’s also entirely manageable if you act promptly and correctly. Income Tax Department’s data network is now sophisticated enough to track virtually every financial transaction linked to your PAN, from the interest on your fixed deposit to the mutual fund you redeemed last October. Therefore, the best strategy is always to reconcile your AIS, TIS, and Form 26AS thoroughly before filing your ITR, not after.

However, if the notice has already arrived, the process is clear: review the mismatch, gather your supporting documents, submit AIS feedback if the data is wrong, file a revised ITR if income was genuinely missed, and respond online within the stipulated deadline. Ignoring the notice is never an option.

The key takeaways from this guide:

AIS is the master financial record; TIS is its simplified, ITR-ready summary; Form 26AS governs TDS credits
Most income tax notices AY 2026-27 arise from unreported FD interest, salary discrepancies, missed capital gains, or incorrect AIS data from third parties

Submit AIS feedback for incorrect data before or after filing ITR

Frequently Asked Questions (FAQs)

What is AIS/TIS mismatch income tax notice?

An AIS/TIS mismatch income tax notice is an official communication from Income Tax Department indicating that Income or transactions you declared in your ITR do not match the data recorded in your Annual Information Statement (AIS) or Taxpayer Information Summary (TIS). It is typically issued under Section 143(1) as an automated intimation or may escalate to a scrutiny notice.

Why did I received AIS mismatch notice for AY 2026-27?

You likely received it because a third party — such as your employer, bank, broker, or mutual fund house — reported income or transactions linked to your PAN that differ from what you declared in your ITR. Common causes include unreported FD interest, capital gains, salary discrepancies, or dividend income.

Is an AIS mismatch notice the same as a scrutiny notice?

Not necessarily. Many AIS mismatch notices for AY 2026-27 are Section 143(1) intimations — automated and not full scrutiny. However, if left unresolved or if large amounts are involved, they can escalate into a Section 143(3) scrutiny assessment.

How to respond to AIS mismatch notice online?

Log in to incometax.gov.in → go to e-Proceedings or Pending Actions → open the notice → review the disputed amount → submit your response online with supporting documents. You can agree (and pay), partially agree, or disagree with an explanation.

What if AIS data itself is incorrect?

Submit feedback on AIS portal at incometax.gov.in under Services → Annual Information Statement. Choose the relevant feedback category (e.g., “Information is not correct” or “Duplicate entry”) and provide details. The reporting entity has 30 days to respond, after which TIS updates automatically.

Can I file my ITR even if my AIS has wrong data?

Yes. You can file your ITR with the correct income figures supported by your own documents, even if AIS shows incorrect data. However, you should submit AIS feedback simultaneously and retain proof of that feedback for reference if a Section 143(1) notice arrives.

What is high value transaction AIS notice?

A high value transaction AIS notice arises when large financial transactions — such as cash deposits above ₹10 lakh, property purchases above ₹30 lakh, or credit card payments above ₹10 lakh — are reported in AIS but not adequately reflected or explained in your ITR. These transactions are reported by banks and registrars under the SFT (Statement of Financial Transactions) framework.

How long do I have to respond to the notice?

Typically, you have 30 days from the date of the notice to submit your response online. However, always check the specific deadline mentioned in your notice, as it can vary. Failure to respond within the deadline can lead to an ex-parte assessment.

Will I face penalty if there was a genuine mistake in my ITR?

If it was an unintentional error (not deliberate concealment), the penalty under Section 270A is generally 50% of the additional tax. Deliberate misreporting attracts up to 200% penalty. Filing a revised ITR before the notice arrives significantly reduces your risk.

What is the difference between AIS and TIS for ITR pre-filling?

AIS shows the raw, transaction-level data reported by third parties. TIS is the processed, aggregated summary of AIS that directly feeds into the ITR pre-fill feature on the portal. When you open a new ITR on incometax.gov.in, the pre-filled income figures come from TIS, not Form 26AS.
