How to match Form 16, AIS and Form 26AS before filing ITR (AY 2026-27)

To match Form 16, AIS and Form 26AS before filing ITR, open all three for the same financial year and compare them in one sitting. Confirm that the salary and TDS in your Form 16 also appear in AIS and Form 26AS, then scan AIS for income your employer never saw, like bank interest, dividends, or a share sale.

Where a number does not agree, do not edit the return to make the screen look tidy. Trace it to its source first, because Form 16 is only your employer's view, AIS is the wider PAN view, and Form 26AS is your tax-credit check.

Key takeaways

• Form 16 shows employer salary and TDS. AIS shows the wider PAN view. Form 26AS is the tax-credit check.
• Match in this order: PAN and year, then salary, then TDS, then other income in AIS.
• AIS usually catches what Form 16 misses: FD and savings interest, dividends, and capital gains.
• If a number mismatches, find the source before you change anything, and never claim a TDS credit you cannot trace.
• As of July 2026, Form 26AS shows only TDS/TCS data, since wider details moved to AIS from AY 2023-24.

What Form 16, AIS and Form 26AS each show

Think of the three as three camera angles on the same year.

Form 16 is your office view. It certifies your salary breakup and the TDS your employer cut.

AIS is the wider PAN view. It pulls in what banks, brokers, companies and other deductors reported against your PAN.

Form 26AS is the tax-credit view. It confirms the TDS/TCS and tax payments sitting to your credit.

Here is the catch: if you match only one of the three, you can miss the exact entry that later triggers a notice, a refund delay, or a wrong return.

The three documents in one table

One small detail trips up a lot of readers.

Some older guides still describe Form 26AS as the main wider tax statement. That is outdated for practical matching today.

The Income Tax Department's AIS FAQ says that from AY 2023-24 onward, Form 26AS on TRACES shows only TDS/TCS data, while other taxpayer details sit in AIS.

So keep one rule fixed while you match: AIS is the wider information view, and Form 26AS is the tax-credit check.

How to view AIS and Form 26AS in minutes

To open AIS, log in to the Income Tax e-filing portal, select `Annual Information Statement (AIS)` on the dashboard, click `Proceed`, open the AIS tile, and pick the financial year.

To open Form 26AS, log in, go to `e-File`, open `Income Tax Returns`, select `View Form 26AS`, accept the disclaimer, and continue to the TDS-CPC or TRACES portal.

Do not memorize the path. The habit that matters is simpler: download all three for the same year before you start accepting any pre-filled number.

Before you file: the 10-minute checklist

Use this order. It keeps the boring checks fast and the risky checks visible.

1. Confirm PAN, name and assessment year on all three documents.
2. Match Form 16 salary with the pre-filled return and the salary entry in AIS.
3. If you changed jobs, keep both Form 16s open. Do not file on the last employer's certificate alone.
4. Match employer TDS in Form 16 with the credit shown in AIS or Form 26AS.
5. Check bank interest. Savings and FD interest rarely appear in Form 16.
6. Check dividends, capital gains and mutual fund entries in AIS, if they apply.
7. Check deductions. Keep proof for anything payroll considered, and understand the rule before claiming anything new.
8. Check the old vs new regime choice. The wrong one changes your final tax.
9. Check bank account details for the refund.
10. Note every mismatch you reviewed, including whom you contacted.

This list is not exciting. That is exactly why it works.

How to match salary across all three (worked example)

Salary is where most people relax too early, so start the match here.

Say your Form 16 shows gross salary of Rs 12,00,000 and TDS of Rs 78,000, and the pre-filled ITR looks almost ready.

Then AIS shows a second salary line of Rs 1,50,000 from an employer you left in April 2025.

That older job is real income for FY 2025-26. File on the last Form 16 alone and you under-report by Rs 1,50,000, which invites a mismatch notice.

Here is how to match it: add both Form 16 salaries, confirm the total against the AIS salary entries, then confirm the combined TDS in Form 26AS.

The point holds even when Form 16 is perfect: Form 16 can be correct and still incomplete for ITR.

How to match TDS and tax credit

Now compare the tax that was cut with the tax that actually reached your PAN.

Take the TDS figure in Form 16 and find the same figure in AIS and Form 26AS. Salary TDS should line up across all three.

For non-salary income, check Form 16A and the TDS lines in AIS. Bank interest often carries a 10% TDS that never shows in Form 16.

The Income Tax Department's ITR-1 FAQ says to download AIS and Form 26AS, check actual TDS, TCS and tax paid, and reconcile any discrepancy with the employer, deductor or bank.

If a credit is missing, do not claim it blindly. Trace it first, or you may lose that credit at processing.

Common mismatch situations and what to do first

The wrong move is to edit numbers until the return looks tidy. The better move is to find the reason for the difference.

If the gap sits mainly in AIS, keep PaisaSeed's AIS mismatch checklist open for the next step. It separates wrong reported information from income you simply forgot to add.

Which document should you trust when they disagree?

Do not treat Form 16, AIS and Form 26AS like three people arguing. They come from different reporting paths, so "the highest number wins" is not a real rule.

For income, verify the source. A bank interest entry in AIS is settled by your interest certificate, not by guesswork.

For tax credit, check whether the deducted tax is actually visible in Form 26AS.

For deductions, keep the proof, not the memory.

One question cuts through most of the confusion: if the Income Tax Department asked you later, which document would you use to explain this number?

Documents to keep ready before you match

Make one folder before you start. A laptop folder, a cloud drive, or a private folder on your phone all work.

• Form 16 from each employer.
• AIS and TIS for the relevant financial year.
• Form 26AS.
• Bank statement or passbook.
• Fixed deposit interest certificates, if applicable.
• Form 16A, if TDS was deducted on non-salary income.
• Rent receipts and landlord details, if claiming HRA.
• Investment proofs, insurance receipts and home loan certificates, where relevant.
• Capital gains statement from your broker or mutual fund platform, if applicable.
• Notes on any AIS feedback or mismatch follow-up.

You will not need every file for your case. But if a number sits in your return, you should know where it came from.

Do you need to upload these documents?

Usually, no. Matching is not the same as attaching a folder of proofs.

For ITR-1, the Income Tax Department FAQ says no documents are to be attached with the return.

The same FAQ still tells taxpayers to compile and study documents such as bank statements, interest certificates, receipts, Form 16, Form 26AS and investment proofs.

So the practical rule is simple: do not upload unless the form asks for it, but keep every record safely.

When to slow down the match

Give the match extra time if:

• You changed jobs during FY 2025-26.
• You have both salary and freelance income.
• A bank deducted TDS on your FD interest.
• You sold shares, mutual funds, property, or virtual digital assets.
• You claimed HRA but did not submit rent proof to payroll.
• You switched between the old and new tax regime.
• AIS shows an entry from a bank, broker, company or deductor you do not recognize.
• Your refund looks too high or too low against the tax already paid.

None of these mean you did something wrong. They only mean Form 16 alone is not enough for a careful return.

If the puzzle is the return form itself and not the numbers, use our guide on which ITR form a salaried person may need for AY 2026-27.

Bottom line

Matching Form 16, AIS and Form 26AS is one sitting, not three separate tasks.

Open all three for the same year, then check salary, TDS, bank interest, deductions, regime and refund details in that order.

If a number does not agree, pause and trace it. That pause is the real work, and it can save you from a wrong claim, a missed income line, or a refund delay.

Before you submit, ask one last thing: can I explain every number in my return from one of these three documents?
