TDS Not Showing in Form 26AS? How to Spot and Fix a Tax Credit Mismatch Before You File

If your employer deducted tax from every payslip but your refund came back smaller than expected, the culprit is almost always a tax credit mismatch in Form 26AS. Under the income tax filing system, the credit you can claim in your return is capped at the figure the department actually sees in your annual statement, not the amount stamped on your salary slip. With the 31 July 2026 due date for non-audit returns (Assessment Year 2026-27) approaching, this is the single most common reason a clean return turns into a demand notice. This guide explains the statutory basis, walks through a worked example with real numbers, and shows you exactly how to fix each type of mismatch before you hit submit.

Form 26AS is your consolidated annual statement for a financial year. It pulls together four categories of credit: tax deducted at source (TDS), tax collected at source (TCS), advance tax, and self-assessment tax deposits, plus any refunds paid during the year. The Income Tax Department maintains it from data filed by deductors and banks, and you can download it from the e-filing portal at incometax.gov.in. When the number you claim does not match the number the department holds, you have a mismatch, and the system resolves it in the government's favour.

What the Section Says

The legal hook is Section 199 of the Income Tax Act 1961, read with Rule 37BA of the Income Tax Rules. Section 199 provides that any deduction of tax at source is treated as a payment of tax on behalf of the person from whose income it was deducted. Rule 37BA then adds the critical qualifier: credit for TDS shall be given for the assessment year on the basis of the information relating to deduction of tax furnished by the deductor to the income tax authorities. In plain English, you get credit for what the deductor has reported, and the vehicle that reports it to you is Form 26AS. The full text is available on indiacode.nic.in, the Government of India's official statute repository.

This is why the briefing from the department is blunt: the tax credit you can take in your return is restricted to the amount reflected in Form 26AS. If your employer deducted Rs 84,000 but has only reported Rs 70,000 to the department, your usable credit on the day of filing is Rs 70,000, regardless of what your Form 16 or payslips show. The shortfall of Rs 14,000 does not disappear, but you cannot claim it until the deductor corrects the record.

The Income Tax Department's own Tax Credit Mismatch FAQ recognises three categories of mismatch, summarised below. Each has a different owner and a different fix, which is why diagnosing the type first saves you from filing the wrong correction.

A fourth practical category sits alongside these: income that appears in your Annual Information Statement but not in Form 26AS. The AIS is wider in scope than 26AS, capturing interest, dividends, securities transactions and more, which is why our companion guide on reconciling your AIS before filing treats the two statements as a pair rather than substitutes.

Worked Example

Consider Meera, a salaried software analyst, for FY 2025-26. Her employer deducted TDS of Rs 7,000 every month, so over 12 months Rs 84,000 left her salary and her Form 16 shows exactly that figure. When she downloads Form 26AS in June 2026 to file her return, only Rs 70,000 appears. The reason is that her employer has filed the TDS returns for the first three quarters (April to December, Rs 63,000) and a part of Q4, but the final March deduction of Rs 7,000 and one correction worth Rs 7,000 have not yet been processed.

Here is what happens depending on which figure she trusts.

Assume Meera's total tax liability for the year is Rs 72,000. If she files trusting her Form 16, she expects a refund of Rs 12,000 (Rs 84,000 paid minus Rs 72,000 due). But because credit is restricted to the Rs 70,000 in 26AS, the system instead sees Rs 70,000 against a Rs 72,000 liability and raises a demand of Rs 2,000 plus interest under the processing intimation. A Rs 12,000 refund flips into a Rs 2,000 bill, a swing of Rs 14,000, entirely because of unreported TDS.

The fix costs nothing but a few days of patience. Meera emails her payroll team, they file the revised Q4 TDS return, and within roughly 7 to 10 working days the missing Rs 14,000 shows up in 26AS. She re-downloads the statement, confirms it now reads Rs 84,000, and only then files, claiming the full credit and receiving her Rs 12,000 refund. You can sanity-check your own expected liability against deductions using our income tax calculator and verify per-payment deductions with the TDS calculator.

How to Fix Each Mismatch Type

The correction path depends entirely on who controls the data, so match your fix to the diagnosis from the table above.

For a TDS or TCS mismatch, the data belongs to the deductor or collector, not you. You cannot self-correct it from your login. The remedy is to ask the employer, bank, or seller to file a revised TDS/TCS return quoting the correct amount and, crucially, your correct PAN. A single wrong digit in your PAN routes the entire credit to someone else, which is why PAN verification is step one. Once the revised return is processed, usually within 7 to 15 days, the credit appears in your 26AS and you file normally.

For an advance tax or self-assessment tax mismatch, you are the owner of the data because you made the payment by challan. If you have not yet filed, simply ensure the challan details (BSR code, challan serial number, date, and amount) are entered correctly in the return, and the credit reconciles. If you have already filed and received an intimation under Section 143(1), you have two routes: file a revised return if the window is open, or submit an online rectification request citing the challan. Self-assessment tax is the balance you pay before filing; if you are unsure of that balance, our guides on self-assessment tax and advance tax explain how the two interact across the four instalment dates of 15 June, 15 September, 15 December and 15 March.

A practical rule: never file to chase a 1 April deadline if your 26AS is short. A delayed filing that claims full credit beats a punctual filing that triggers a demand and a refund you then have to fight for.

Common Mistakes

These are the errors that surface repeatedly in processing under Section 143(1), drawn from the department's own mismatch guidance.

Trusting Form 16 over Form 26AS. Form 16 records what your employer deducted; Form 26AS records what the department received. When they differ, the return is processed on 26AS. Always reconcile the two before filing, not after.

Filing in the first week of April. Many Q4 TDS returns are filed by deductors only towards the 31 May statutory deadline, so 26AS for the January to March quarter is often incomplete until early June. Filing on 5 April with a 26AS that is missing Q4 credit is the most avoidable demand of the year.

Ignoring a PAN error. If TDS was deducted against a wrong or inoperative PAN, it will never reach your 26AS no matter how long you wait. Verify that the deductor holds your correct ten-character PAN before assuming the return simply needs reprocessing.

Mixing up 26AS and AIS. The two statements overlap but are not identical. Income such as savings-bank interest or dividends may appear in your AIS but not in 26AS, and missing TDS on that income is still your liability. Reconcile both, and use our old vs new regime calculator to confirm the deductions you are entitled to under your chosen regime.

Forgetting refunds reduce future credit. Form 26AS also records refunds already paid to you during the year. Reading the statement selectively and ignoring the refund row can lead to double-counting and an inflated claim that the system rejects.

FAQ

Why does my Form 26AS show less TDS than my salary slips?

Because your employer has deducted the tax but not yet reported it to the Income Tax Department, or has reported it against a wrong PAN. Under Rule 37BA, credit is given only on the basis of the deductor's filing, so until the revised TDS return is processed, the missing amount, for example Rs 14,000 of a Rs 84,000 deduction, will not appear in 26AS.

Can I claim TDS that is not in my Form 26AS?

In practice, no. The department restricts your credit to the amount reflected in Form 26AS, so claiming more triggers a mismatch and a demand under Section 143(1). The correct sequence is to get the deductor to file a revised return first, confirm the credit appears, and then file.

How long does it take for a corrected TDS return to reflect in 26AS?

Typically 7 to 15 working days after the deductor files the revised statement, though it can be quicker. Re-download Form 26AS from the incometax.gov.in portal to confirm the updated figure before you file.

What do I do if I have already filed and the credit was short?

If you received an intimation under Section 143(1), you can file a revised return while the window remains open, or submit an online rectification request. For advance or self-assessment tax mismatches, attach the correct challan details (BSR code, serial number, date and amount) so the credit reconciles.

Is Form 26AS the same as the AIS?

No. Form 26AS focuses on TDS, TCS, advance tax, self-assessment tax and refunds, while the Annual Information Statement is broader, capturing interest, dividends and securities transactions. Reconcile both before filing, because income in the AIS that is missing from 26AS is still taxable.

Who is responsible for fixing a TDS mismatch, me or my employer?

Your employer, or whichever deductor made the deduction. Only the deductor can file the revised TDS return that updates 26AS. Your job is to flag the shortfall, confirm your PAN is correct, and wait for the corrected statement before claiming the credit.

Will a mismatch delay my refund?

Yes. If you claim more credit than 26AS shows, the excess is disallowed and any refund is recomputed on the lower figure, often turning an expected refund into nil or a demand. Reconciling first is the only reliable way to protect the full refund.
