AIS Mismatch Before ITR Filing: What Should You Check First?

Here is how to fix an AIS mismatch before filing ITR: do not treat it as a portal error to delete. First identify the type of mismatch, then match AIS against your own records.

Do not file in a hurry, and do not blindly copy the AIS figure. Compare AIS with Form 16, Form 26AS and your bank and investment records, give feedback only where the data is genuinely wrong, then file.

Key takeaways

• An AIS mismatch does not always mean AIS is wrong. Often your Form 16 is simply incomplete.
• Fix it in this order: check AIS, match records, give feedback, then file.
• Form 16 usually misses bank interest, dividends and mutual fund sales that AIS still reports.
• A Form 26AS TDS credit mismatch is a separate problem, sorted out with the deductor.
• Give AIS feedback only with proof, and only where data is duplicate, wrong, or not yours.

Here is the honest part: the return felt simple, and now one extra line in AIS is making you doubt the whole thing. Work through the mismatch type first.

Quick answer: first find out what kind of mismatch it is

An AIS mismatch before filing ITR does not always mean the tax portal is wrong. Sometimes AIS is wrong. Sometimes your own records are incomplete. Sometimes it is not AIS at all, but a tax-credit mismatch in Form 26AS.

So match what you see against this before you touch anything:

The result? Your first job is not filing. It is matching records.

If you are still gathering documents, keep PaisaSeed's Form 16, AIS and Form 26AS checklist open. It will help you check the same documents in the right order.

What is AIS actually showing you?

AIS stands for Annual Information Statement.

In plain words, it shows information reported against your PAN: salary, TDS, TCS, interest, dividends, securities transactions, tax payments, refunds and more.

As of July 2026, the Income Tax Department's AIS FAQ says AIS gives you a view of this information before filing and includes a facility to give online feedback.

That last part matters.

AIS is not just a screen to stare at. If something looks wrong, you can flag it through the portal. But feedback comes after you check your own records, not before.

Do this 5-minute record match before filing

Open your documents side by side.

1. Form 16: salary, employer TDS, deductions and exemptions.
2. AIS: reported income, TDS, interest, dividends and investment transactions.
3. Form 26AS: tax credits, TDS, TCS, tax payments and related tax-credit data.
4. Bank records: savings interest, FD interest and tax certificates.
5. Investment records: broker statement, mutual fund capital gains statement or property sale documents.

Now ask one question:

Is AIS wrong, or did I forget to include something?

That single question decides your next move.

If AIS shows bank interest you forgot, the answer is not "delete it from AIS". Check the interest amount and include the correct income in your return.

Here's the catch: if AIS shows a duplicate or a genuinely wrong amount, that is when feedback comes in.

Common AIS mismatch cases for salaried people

AIS shows bank interest missing from Form 16

This is the most common one.

Form 16 comes from your employer. It will not capture every rupee of savings interest, FD interest or other income outside your salary.

So if AIS shows interest income, check your bank interest certificate or account statement. If the amount is correct, include it in the return even though Form 16 skipped it.

AIS shows a mutual fund or share sale

This one catches salaried taxpayers off guard.

You may think you only have salary income. But if you sold mutual funds or shares during the year, AIS will show those securities transactions.

That can change which ITR form you use. If capital gains are involved, do not assume ITR-1 fits just because you are salaried. PaisaSeed's which ITR form guide walks through the filing choice.

AIS shows salary that does not match Form 16

Check whether you changed jobs, received arrears, had reimbursements, or hold more than one Form 16.

If you worked for two employers in the same financial year, a single Form 16 will not tell the whole story.

Form 26AS shows a TDS credit issue

This is different from a normal AIS mismatch.

Form 26AS mainly matters for TDS and tax-credit details. The Income Tax Department's tax-credit mismatch FAQ explains that a mismatch shows up when the tax credit you claim does not match the amount available in Form 26AS.

If your TDS credit is missing or different, check the deductor, PAN, challan and certificate details. Sometimes you have to contact the deductor, your employer, bank or buyer, to fix the reporting at their end.

When should you give AIS feedback?

Give AIS feedback only after you have checked your records and the information in AIS still looks wrong, duplicate, denied, or not fully correct.

For example:

• the same income appears twice
• the amount does not match your official statement
• a transaction does not belong to you
• income is reported under the wrong category
• data is partly correct but needs a fix

Keep proof ready before you submit feedback: a Form 16, bank certificate, Form 26AS, broker statement, mutual fund capital gains statement, challan receipt or employer clarification.

And do not guess inside the feedback box. A wrong correction can create more confusion than the original mismatch.

Should you wait after giving feedback?

If the mismatch is small and the correct income is clear from your records, you can usually file with the right values after a careful review.

But if it touches TDS credit, capital gains, large income, refund amount, or the ITR form itself, slow down.

This is the boring part. It is also the part that protects you.

Before filing, check whether the issue changes any of these:

• total income
• tax payable
• refund claim
• TDS credit
• ITR form selection
• capital gains reporting
• loss reporting

If even one of these changes, treat the mismatch seriously.

What if AIS is higher than your actual income?

Do not blindly copy the higher AIS number. But do not blindly ignore it either.

First, find the source of the entry. AIS shows information source details, such as the reporting entity and category, so match those against your documents.

If AIS is higher because of a duplicate or wrong report, use feedback and keep proof.

If AIS is higher because Form 16 left out bank interest, a dividend or an investment sale, then your return should reflect the correct taxable income, not just Form 16.

Here is where people get stuck: both numbers look official.

But official-looking is not the same as final. Your job is to file the correct return using the latest records you can actually verify.

A worked example with numbers

Say your Form 16 shows only salary and employer TDS. Then AIS adds four entries:

• savings account interest of Rs 4,000
• FD interest of Rs 18,000
• a dividend of Rs 2,500
• one mutual fund sale

Do the quick math: that is Rs 24,500 of income outside salary, before counting the mutual fund gain. This does not automatically mean AIS is wrong.

It usually means Form 16 only shows the employer side of your income. So check bank certificates and investment statements next.

If the mutual fund sale created capital gains, your form choice may change too. That is why AIS mismatch and ITR form selection are linked.

If your bigger question is salary below rebate level, TDS and whether to file at all, read PaisaSeed's salary below 12 lakhs ITR guide after this.

The final check before you file

Run this checklist before you submit your return:

1. Did you compare AIS with Form 16?
2. Did you compare TDS credit with Form 26AS?
3. Did you check bank interest and FD interest?
4. Did you check dividend and securities transactions?
5. Did you check whether any capital gains affect the ITR form?
6. Did you give AIS feedback only where the data looks wrong?
7. Did you keep proof for every corrected or ignored entry?
8. Did you avoid filing only from Form 16 when AIS shows extra income?

Clear on all eight? You can move ahead calmly.

Still unsure on one? Pause and verify before filing.

Bottom line

Bottom line: an AIS mismatch before ITR filing feels stressful only because it shows up at the last stage.

The fix usually starts with one question: is the portal data wrong, or did your own filing data miss something?

Answer that first. Then decide whether to give feedback, add income, fix a tax credit, or switch the ITR form.

That is far safer than filing first and understanding the mismatch later.
