With increasing digitization and data integration, the Income Tax Department of India has introduced robust tools to pre-fill and cross-verify taxpayer information — primarily through AIS (Annual Information Statement) and TIS (Taxpayer Information Summary). While these tools are extremely useful, they can sometimes contain errors or mismatches, which if left unchecked, may result in wrong tax filing, scrutiny, or even penalties.
In this article, we explain what AIS and TIS are, why mismatches occur, and how to correct them before filing your ITR.
What is AIS and TIS?
Annual Information Statement (AIS)
AIS is a comprehensive report of a taxpayer's financial transactions and tax-related information, collated from various sources such as banks, mutual fund houses, registrars, employers, and government portals.
AIS includes:
- Salary and pension details
- Interest from savings and fixed deposits
- Dividend income
- Securities transactions (stocks, mutual funds)
- Sale/purchase of property
- Foreign remittances
- TDS/TCS details
- GST turnover (in some cases)
Taxpayer Information Summary (TIS)
TIS is a summary view based on the data in AIS. It shows the processed value and derived value of each item — which may be used to pre-fill your Income Tax Return (ITR).
What is an AIS–TIS Mismatch?
A mismatch occurs when the information in AIS/TIS is incorrect, duplicated, or incomplete compared to your actual income or documents. Some common mismatch scenarios include:
- Interest income shown is higher than what you actually received
- TDS is credited to the wrong PAN
- Duplicate entries for the same transaction
- Capital gains data wrongly reported
- Transactions that belong to another taxpayer
If you file your ITR without rectifying these mismatches, you might receive:
- A tax demand
- A notice under Section 143(1)(a) or 139(9)
- Scrutiny assessment or reassessment notice
How to Correct AIS & TIS Mismatch Before Filing ITR
Follow this step-by-step guide to check and correct mismatches:
Step 1: Access the AIS Portal
- Visit the Income Tax e-filing portal
- Login using your PAN and password
- Go to “Services” →“Annual Information Statement (AIS)”
- You will be redirected to the AIS portal
Step 2: Download AIS and TIS
- View both AIS and TIS in HTML or PDF format
- Compare them with your Form 16, Form 16A, bank statements, broker reports, and other financial records
Step 3: Identify Mismatches
Look out for:
- Extra or duplicate entries
- Wrong amounts
- Transactions not related to you
- Missing TDS credit despite deduction
Step 4: Submit Feedback for Correction
- Click “Submit Feedback”next to the incorrect item in AIS
- Choose the correct feedback option:
- Information is correct
- Information is not fully correct
- Information relates to other PAN/year
- Duplicate information
- Information is denied
- Provide the correct value and remarks
- Submit and retain acknowledgment
Step 5: Wait for AIS Update
- The feedback is processed, and the AIS gets updated if accepted.
- You can file ITR after correcting the mismatch or file with explanationif the correction isn’t reflected in time.
Things to Keep in Mind
- Always cross-verify AIS & TIS before ITR filing, especially for salaried individuals, senior citizens, and NRIs with multiple income sources.
- If your Form 26ASand AIS show different TDS details, rely on AIS but confirm via feedback if necessary.
- Filing ITR without correcting mismatches can delay refund processingor result in reassessment notices.
Conclusion
AIS and TIS are excellent tools for transparent and simplified income tax filing. However, being auto-generated, they may not always reflect accurate data. As a responsible taxpayer, it is crucial to review, verify, and correct any discrepancies before filing your ITR for FY 2025–26.
