If you’ve ever logged into your income tax portal and felt confused seeing mismatched figures in your Annual Information Statement (AIS), you’re not alone. Many taxpayers—especially freelancers, salaried individuals, and business owners—face discrepancies between AIS data and their actual financial records.
At ChennaiAccounts, we regularly help clients resolve such issues as part of our Accounting Services In Chennai and Income Tax Filing In Chennai support system. This guide breaks everything down in a simple, practical, and expert way so you can correct AIS errors without stress.
What is AIS (Annual Information Statement)?
The Annual Information Statement (AIS) is a detailed financial summary provided by the Income Tax Department. It includes:
- Salary income
- Bank interest
- Dividend income
- Mutual fund transactions
- TDS/TCS details
- High-value transactions
- Property-related transactions
AIS is more advanced than Form 26AS because it shows expanded financial activity, not just tax deducted at source.
However, because AIS pulls data from multiple institutions, errors and mismatches are common.
Why AIS Errors Happen
Understanding the root cause helps in fixing the issue faster.
Common reasons include:
| Reason | Explanation |
|---|---|
| Incorrect PAN entry | Banks or institutions may incorrectly report your PAN |
| Duplicate reporting | Same income reported multiple times |
| Missing corrections from banks | Institutions not updating revised data |
| Timing differences | Income reported in different financial years |
| Wrong transaction mapping | Investment or mutual fund misclassified |
| TDS mismatch | Difference between deducted and reported tax |
These issues can directly impact your tax filing accuracy if not corrected.
Why It’s Important to Fix AIS Errors Early
Ignoring AIS errors may lead to:
- Higher tax liability calculation
- Income mismatch notices from IT department
- Scrutiny during filing
- Delays in refunds
- Incorrect ITR filing
This is why professionals offering Income Tax Filing In Chennai always verify AIS before filing returns.
At ChennaiAccounts, we ensure AIS reconciliation is part of every filing process.
Step-by-Step Guide: How to Correct Errors in AIS
Let’s break it down in a simple actionable process.
Step 1: Log in to the Income Tax Portal
Go to the official income tax website and:
- Login using PAN
- Navigate to AIS (Annual Information Statement) section
- Download or view your AIS and TIS (Taxpayer Information Summary)
Step 2: Identify the Error
Compare AIS with your records:
- Bank statements
- Salary slips
- Investment proofs
- TDS certificates
Mark mismatches such as:
- Incorrect income amount
- Duplicate entries
- Missing transactions
- Wrong financial year
Step 3: Submit Feedback on AIS
This is the official correction mechanism.
You can submit feedback in categories like:
- Information is incorrect
- Duplicate entry
- Information does not belong to me
- Information relates to different PAN
- Information is already reported correctly in ITR
Step 4: Choose the Correction Type
When raising a correction request, you will see options such as:
| Correction Type | When to Use |
|---|---|
| Denied | Transaction not related to you |
| Partially correct | Amount mismatch |
| Fully correct | Data already accurate |
| Not applicable | Wrong reporting |
Choose carefully, as this affects how the system updates your AIS.
Step 5: Provide Supporting Remarks
Always add a clear explanation like:
- “Bank interest incorrectly reported for closed account”
- “Duplicate dividend entry from same mutual fund”
- “TDS already reflected in Form 26AS”
Clear explanations speed up resolution.
Step 6: Wait for Processing
Once submitted:
- The institution reviews the correction
- Updated data is reflected in AIS/TIS
- You can track status in the portal
Processing may take a few days to a few weeks depending on the institution.
Expert Tips from ChennaiAccounts
Here are practical insights from our experience in Accounting Services In Chennai:
✔ Always reconcile AIS before filing ITR
Never rely solely on AIS or 26AS—match it with your actual documents.
✔ Don’t ignore small mismatches
Even ₹100–₹500 differences can lead to notices later.
✔ Keep investment proofs ready
Mutual funds, FD receipts, and brokerage statements help validate corrections.
✔ File early
Early filing gives time to correct AIS before deadline pressure.
