If you have filed your income tax return and received an intimation about a tax credit mismatch — or noticed that your TDS is not reflecting correctly in Form 26AS — you are not alone. This is one of the most common tax-related issues Indian taxpayers face. Understanding why it happens and how to fix it can save you from unnecessary tax demands, delayed refunds, and compliance notices. If you earn interest from fixed deposits — such as a Bajaj Finance Fixed Deposit offering up to 7.75% p.a. for senior citizens — ensuring TDS is correctly linked to your PAN is particularly important.

Introduction
What is tax credit mismatch issue?
A tax credit mismatch occurs when the TDS amount reflected in your Form 26AS does not match the TDS claimed in your income tax return. The Income Tax Department reconciles these figures during return processing — and any discrepancy triggers either a demand notice, a reduced refund, or an intimation under Section 143(1). Simply put, if what your deductor has deposited and reported does not align with what you have claimed, the system flags it as a mismatch.
Common reasons behind a TDS mismatch in Form 26AS
TDS mismatches rarely happen due to taxpayer error alone. In most cases, the issue originates at the deductor's end — a bank, employer, or financial institution responsible for deducting and depositing TDS on your behalf. Here are the most common causes:
1. Wrong PAN quoted by deductor
If the deductor — such as a bank deducting TDS on FD interest — quotes an incorrect PAN while filing the TDS return, the credit does not get linked to your account in Form 26AS. The TDS is deposited with the government but simply does not appear against your PAN. This requires the deductor to file a correction in their TDS return.
2. Delay in filing TDS return
Deductors are required to file quarterly TDS returns within specified deadlines. If they file late, the credit may not appear in your Form 26AS at the time you file your ITR — creating a mismatch even though the tax was deducted correctly. The credit typically appears once the deductor files or updates the return.
3. Incorrect assessment year mentioned
TDS returns must specify the correct assessment year to which the deduction relates. If the deductor mentions the wrong assessment year — say AY 2024-25 instead of AY 2025-26 — the credit is posted to the wrong year in the system, making it appear absent from your current year's Form 26AS.
4. Data entry errors in challan details
Errors in challan details — such as the BSR code, challan serial number, or date of deposit — during TDS return filing can prevent the credit from being correctly matched to your PAN. Even a minor typographical error can cause the system to fail to link the payment to your account.
5. TDS deposited but not linked to PAN
In some cases, TDS is deposited correctly with the government but the deductor has not yet filed or updated their TDS return with your PAN details. Until the return is filed and processed, the credit does not appear in Form 26AS — even though the money has been paid to the government.
How to check if you have received an intimation or notice having tax credit mismatch?
After filing your ITR, the Income Tax Department processes your return and reconciles the TDS claimed against Form 26AS data. If a mismatch is found, it typically manifests in one of the following ways:
1. Notice under Section 143(1)
This is the most direct signal of a tax credit mismatch. The department issues an intimation under Section 143(1) stating that the TDS claimed in your return does not match the credit available in Form 26AS. The notice will specify the discrepancy amount and may raise a tax demand for the difference — or reduce the refund amount you were expecting. It is important to read this intimation carefully and not ignore it, as it requires a response within the specified timeframe.
2. Delay in tax refund processing
If your ITR is stuck in processing for an unusually long time, a TDS mismatch is often the reason. The system holds up refund processing when it cannot reconcile the claimed credit with the available data. Checking your Form 26AS and AIS for discrepancies is the first step when a refund is delayed beyond the typical processing period.
3. ITR rejection or demand raised
In certain cases, a significant mismatch may result in the ITR being processed with a demand raised against the taxpayer — essentially asking you to pay tax on the TDS amount that could not be matched. This is not a penalty but a computational adjustment, and it can be disputed through the rectification process once the underlying mismatch is resolved.
4. Loss of legitimate TDS credit
Perhaps the most financially impactful consequence — if the mismatch is not addressed, you may permanently lose credit for TDS that was legitimately deducted on your income. This is particularly relevant for TDS on FD interest, where the deducting bank may have filed returns with errors that go uncorrected unless the taxpayer actively follows up.
How to rectify tax credit mismatch?
Once you have identified a mismatch, there are two parallel paths to resolution — one through the Income Tax Portal directly, and the other through your deductor. In most cases, both actions are needed simultaneously.
How to submit a rectification request on the Income Tax Portal
- Log in to the Income Tax e-filing portal at incometax.gov.in using your PAN and password.
- Navigate to e-File and select Rectification.
- Choose the relevant assessment year for which the mismatch exists.
- Select Tax Credit Mismatch as the rectification type.
- Review the pre-filled data and make corrections where the system allows — particularly in cases where you need to update TDS schedule details.
Submit the rectification request and note the acknowledgement number for follow-up.
How to request correction through your deductor
- Contact the deductor — your bank, employer, or financial institution — in writing, specifying the discrepancy in their TDS return.
- Request them to file a correction statement with the TDS return to update the incorrect PAN, assessment year, or challan details.
- Follow up to confirm the correction has been filed and verify that Form 26AS has been updated — typically within 7 to 10 working days of the correction being processed.
How to reconcile Form 26AS, AIS, and Form 16 to avoid mismatch
Proactive reconciliation before filing your ITR is the most effective way to avoid mismatches entirely. Here is how to approach it:
- Download all three documents before filing: Obtain your Form 26AS and Annual Information Statement (AIS) from the income tax portal, and your Form 16 or Form 16A from your employer and deductors respectively.
- Match TDS figures line by line: For each TDS entry in Form 16 or Form 16A, verify that the corresponding amount appears correctly in Form 26AS under your PAN. Any entry present in one but absent in the other signals a potential mismatch.
- Check the AIS for additional income disclosures: The AIS contains a broader set of financial transactions reported by third parties — including FD interest, dividends, and securities transactions. Ensure that all income disclosed in the AIS is accounted for in your ITR.
- Verify assessment year and deductor TAN: Confirm that TDS entries in Form 26AS are linked to the correct assessment year and that the deductor's TAN matches across documents.
- Act before filing — not after: If you identify a discrepancy during reconciliation, contact the deductor to file a correction before submitting your ITR. Filing with a known mismatch increases the likelihood of a demand notice or delayed refund.
Filing a revised ITR after TDS mismatch correction
Once the deductor has filed a correction and Form 26AS has been updated, you may need to revise your original ITR to reflect the corrected TDS credit.
- Check Form 26AS after the correction is processed: Allow 7 to 10 working days after the deductor files the correction before verifying the update in Form 26AS.
- Compare with your original ITR: If the corrected Form 26AS now shows higher TDS credit than what you claimed in your original return, a revised ITR may result in a higher refund or elimination of a demand.
- File the revised return online: Log in to the income tax portal, navigate to your filed returns, and select the option to file a revised return under the relevant assessment year.
- Attach a clear note of changes: While filing, ensure the revised schedule accurately reflects the corrected TDS figures as they now appear in Form 26AS.
How FD interest TDS causes tax credit mismatch and how to fix it
Fixed deposit interest is one of the most common sources of TDS mismatch for individual taxpayers. Banks deduct TDS on FD interest at 10% when annual interest exceeds Rs. 40,000 (Rs. 50,000 for senior citizens) — but errors in PAN linking, delayed TDS return filing, or incorrect assessment year mapping can prevent this credit from appearing in Form 26AS.
If you hold a Bajaj Finance Fixed Deposit — which offers tenure flexibility from 12 to 60 months with investment starting at Rs. 15,000 — ensure your PAN is correctly registered with Bajaj Finance at the time of booking. This single step prevents the most common cause of FD-related TDS mismatch.
- Verify your PAN is correctly linked to your FD account before each renewal or fresh booking.
- Download Form 16A from your FD provider each quarter and cross-check against Form 26AS.
- Report FD interest income in the correct head of your ITR — even if TDS has been deducted — to avoid any discrepancy between AIS reported figures and your ITR.
Conclusion
A TDS mismatch is frustrating — but it is fixable. The key is to catch it early, either during reconciliation before filing or promptly after receiving an intimation. Whether the issue lies with your employer, your bank, or a fixed deposit provider, the resolution path is clear — contact the deductor, request a correction, verify Form 26AS, and file a rectification or revised return if needed. Staying on top of your TDS credits is not just a compliance requirement — it is how you ensure every rupee of tax you have paid is properly accounted for.
