AIS vs Form 26AS Mismatch: What to Check Before Filing Your ITR

Before you submit your income tax return, compare your Form 16, bank interest certificates, Annual Information Statement (AIS), Taxpayer Information Summary (TIS) and Form 26AS. A small mismatch can delay processing, create an unnecessary notice, or make your refund take longer.

The Income Tax Department now gives taxpayers more visibility into income, TDS and financial transaction data through AIS and TIS, while Form 26AS continues to be an important tax credit reference. These statements are useful, but they are not a substitute for your own records. The safest approach is to reconcile them before filing the ITR instead of correcting mistakes after a notice arrives.

Why AIS and Form 26AS may not match

A mismatch does not always mean tax evasion or a filing mistake. It often happens because information is reported by different entities at different times. Your employer, bank, mutual fund platform, broker, tenant, buyer or other reporting party may update details after you first download the statement. Sometimes the same income appears under a different description, or a corrected TDS return is filed later.

Common reasons include delayed TDS return updates, revised Form 16, incorrect PAN tagging, bank interest reported branch-wise, joint account income appearing in one PAN, duplicate transaction reporting, capital gains data that does not match broker statements, or AIS values that need taxpayer feedback.

7 checks to complete before filing

1. Match salary with Form 16 and AIS

Start with salary income because most salaried taxpayers rely heavily on Form 16. Confirm employer name, TAN, gross salary, taxable salary, deductions reported by the employer and TDS. If AIS or TIS shows a different salary figure, check whether it includes arrears, perquisites or a correction made by the employer.

2. Compare TDS in Form 26AS, AIS and Form 16

Form 26AS is useful for tax credit verification. If TDS is missing or lower than expected, do not simply claim the higher amount in your ITR. First ask the deductor to check whether the TDS return was filed correctly with your PAN. Claiming credit that is not reflected properly can slow down processing.

3. Review bank interest and small income items

Savings interest, fixed deposit interest, recurring deposit interest and other small income items are often missed because they do not always appear in Form 16. AIS may show these items even when no tax was deducted. Add them to the return under the correct head and then claim eligible deductions separately where allowed.

4. Reconcile capital gains with broker statements

For shares, mutual funds and other securities, use your broker or registrar statements to calculate gains carefully. AIS can help identify transactions, but the final ITR values should consider cost, sale value, holding period, grandfathering rules where applicable, and exempt or taxable classification. Do not file only from summary numbers if you traded frequently.

5. Check rent, property sale and high-value transactions

If AIS shows property sale, rent, cash deposit, credit card payment, foreign remittance or other high-value information, match it with your documents. Some entries may be informational, but you should understand why they appear before filing. Ignoring unexplained entries can increase the chance of a compliance query.

6. Use AIS feedback when information is wrong

If an AIS entry is duplicate, belongs to another taxpayer, has an incorrect amount, or is otherwise not accurate, use the feedback facility available through the income tax portal. Keep screenshots and supporting documents. Feedback does not replace correct ITR reporting, but it helps create a record of your position.

7. Re-download statements close to filing

If you downloaded AIS or Form 26AS many days ago, download them again before final filing. TDS returns, corrections and reporting data can change. This is especially important when you are expecting a refund or when your employer, bank or deductor recently made a correction.

What to do if there is still a difference

Do not panic and do not blindly copy one statement into the ITR. Build a reconciliation sheet with four columns: your record, Form 16 or certificate value, AIS/TIS value, and Form 26AS value. Then mark each difference as timing difference, wrong reporting, duplicate entry, missing tax credit, or income that must be added.

If tax credit is missing, follow up with the deductor. If income is missing from AIS but you earned it, report it correctly. If AIS shows extra income that is genuinely wrong, submit feedback and keep evidence. A well-documented reconciliation is often enough to explain the position if the department later asks for clarification.
