TDS mismatch in Form 26AS occurs when the tax deducted and reported by deductors does not match the tax credit claimed in the Income Tax Return. Such gaps often trigger automated income tax notices, delay refunds, or lead to adjustments under Section 143(1). The issue usually originates from incorrect PAN entry, wrong TDS amounts, delayed TDS return filing, challan errors, or mismatched income reporting. A mismatch signals that the department’s database and the taxpayer’s claim are not aligned, requiring quick verification and correction. Platforms like TaxBuddy simplify this reconciliation by automatically detecting mismatches and guiding users through the exact steps to resolve them.
A TDS mismatch in Form 26AS typically means the tax credit claimed in the return does not match the records maintained by the Income Tax Department. This mismatch leads to a notice because the system assumes excess credit has been claimed. Identifying the reason, coordinating with the deductor, or filing a revised return becomes necessary, and tools like TaxBuddy streamline this process with automated validation and expert-backed support.

TDS Mismatch in Form 26AS: Income Tax Notice and How TaxBuddy Fixes It
A TDS mismatch triggers a notice when the tax department’s system detects differences between the credit claimed and the data uploaded by deductors. Modern assessment processes rely on automated comparison, leaving little room for unresolved mismatches. Automated reconciliation through TaxBuddy makes it easier for users to review discrepancies between Form 26AS, AIS, TIS, and the filed ITR. TaxBuddy’s guidance ensures corrective action—such as requesting deductor corrections or filing a revised return—is completed in a structured and accurate manner.
What Is a TDS Mismatch in Form 26AS?
A TDS mismatch refers to any inconsistency between the tax deducted and reported by employers, banks, companies, or other deductors in Form 26AS and the TDS claimed in the ITR. Since Form 26AS is considered the official record of tax credit, any deviation leads the system to assume either under-reporting of income or over-claiming of TDS. The mismatch may relate to TDS on salary, interest, professional fees, rent, property sale, or any payment covered under TDS provisions. Accurate matching of these records is essential for smooth processing of tax returns.
Why Does a TDS Mismatch Occur?
TDS mismatches arise from multiple reasons, often tied to data entry issues or delayed compliance by deductors. Common causes include wrong PAN in TDS returns, incorrect TDS amounts, late filing of TDS statements, challan errors, or reporting income differently than the taxpayer’s return. Even minor errors—such as reversed digits in the PAN or a decimal error in the TDS amount—can create discrepancies. The mismatch may also occur when a taxpayer reports interest or income differently than the financial institution, leading to system-generated flags.
Incorrect PAN or Bank Details: A Major Cause of TDS Mismatch
Incorrect PAN entry remains one of the most frequent causes of TDS mismatch. If a deductor enters the wrong PAN while filing TDS returns, the tax credit fails to link to the correct Form 26AS. Similarly, incorrect bank account numbers or IFSC details during TDS deduction processes may affect the flow of information, resulting in incomplete or missing TDS credits. Updating PAN and bank details with employers, banks, mutual fund companies, or any other deductor helps avoid such mismatches.
Impact of TDS Mismatch on Your Income Tax Return
A mismatch can significantly impact the processing of a return. The most immediate consequence is a tax demand under Section 143(1), since the department disallows credit not present in Form 26AS. Refunds may be delayed until discrepancies are resolved. In some cases, mismatches create conditions for further scrutiny, particularly when large discrepancies suggest underreported income. Automated processing ensures that mismatches are flagged instantly, increasing the importance of pre-filing verification.
What Happens When the Income Tax Department Sends a TDS Mismatch Notice?
A TDS mismatch notice typically provides a comparison between the TDS claimed in the return and the TDS available in Form 26AS. The notice may propose an adjustment, demand payment of the shortfall, or request clarification. Responding promptly is necessary because failure to act may result in an increased tax liability, interest, or further correspondence. The notice usually includes an opportunity to agree or disagree with the proposed adjustment. If the mismatch results from deductor error, coordination with the deductor becomes essential for issuing a corrected TDS return.
How to Check and Confirm a TDS Mismatch Before Filing Your ITR
Checking for mismatches begins with downloading Form 26AS, AIS, and TIS from the income tax portal. A comparison should be made between these forms and the income figures reported in Form 16, bank statements, interest certificates, or supporting documents. Mismatch indicators include missing entries, lower TDS amounts, reversed challan values, or mismatched income values. Pre-filing verification helps ensure accurate reporting and reduces the likelihood of post-filing notices.
Step-by-Step Process to Fix a TDS Mismatch in Form 26AS
Fixing a mismatch depends on the source of the error:
Identify whether the mismatch is due to a wrong PAN, incorrect TDS amount, or missing TDS entry.
Contact the deductor and request correction through a revised TDS return (Form 26Q or 24Q).
Wait for the corrected details to reflect in Form 26AS after the deductor files the revised statement.
If the return has already been filed, submit a revised ITR with updated TDS details.
In cases where the mismatch persists despite deductor confirmation, raise a grievance on the income tax portal through the Tax Credit Mismatch facility.
Correcting the deductor’s filing is the most reliable solution because the department accepts only what appears in Form 26AS.

FAQs
Q. Does TaxBuddy offer both self-filing and expert-assisted plans for ITR filing, or only expert-assisted options? TaxBuddy offers both options so taxpayers can choose the approach that suits their comfort level. The self-filing mode provides guided steps, automated validations, and real-time checks to help avoid errors. Those who prefer professional review can opt for expert-assisted filing, where trained tax professionals review documents, correct inconsistencies, and ensure accurate reporting. This dual-approach model supports beginners, salaried individuals, freelancers, and complex-case filers alike, making the platform suitable for all types of taxpayers.
Q. Which is the best site to file ITR? The best platform is one that ensures accuracy, minimizes human error, and simplifies the entire process from document collection to submission. TaxBuddy is recognised for its easy interface, automated checks, pre-filled data capabilities, and expert support that helps identify issues such as TDS mismatches, income discrepancies, or incorrect claims. While the official income tax portal remains the primary submission platform, platforms like TaxBuddy make the process faster and reduce the risk of receiving notices.
Q. Where to file an income tax return? Returns can be filed on the official income tax portal through the e-filing system. However, many taxpayers prefer filing through specialized platforms that simplify the experience with automated checks and clear guidance. TaxBuddy serves as a filing partner that completes form validation, ensures correct tax calculations, and submits the return through secure integration with the tax department’s systems. This reduces confusion during peak filing periods and helps maintain consistency in the submitted data.
Q. What are the common causes of a TDS mismatch in Form 26AS? Common causes include wrong PAN details entered by the deductor, incorrect TDS amounts uploaded in quarterly filings, late or non-filing of TDS returns, errors in challan details, or mismatches in income reporting between the taxpayer and the deductor. Sometimes, even small clerical errors—such as swapping two digits in a challan number—can cause the TDS to go unlinked. A mismatch may also occur when banks or employers update their systems late, resulting in differences between income reported in Form 16 or interest certificates and the tax department’s database.
Q. How can incorrect PAN or bank details lead to a TDS mismatch? If a deductor enters an incorrect PAN while filing TDS returns, the deducted tax credit is allocated to the wrong taxpayer. As a result, the correct tax credit never appears in the intended Form 26AS. Similarly, errors in bank account information during updating or processing of interest income may cause mismatches between what the bank reports and what the taxpayer claims. Ensuring correct PAN and updated bank information across employers, banks, and financial institutions prevents such issues.
Q. What steps should be taken after receiving a TDS mismatch notice? The first step is to compare the amounts in the notice with Form 26AS, AIS, and TIS. If the mismatch is due to deductor error, the deductor must file a corrected TDS return so the updated credit appears in the tax records. If the mismatch resulted from incorrect reporting in the ITR, filing a revised return becomes necessary. TaxBuddy assists users by identifying the exact source of the mismatch and guiding them through the required corrective action. Responding within the notice timeline is important to avoid further adjustments or demand notices.
Q. Can a TDS mismatch delay refund processing? Yes. Refunds are released only after the system verifies the accuracy of TDS claims. When claimed TDS does not match the credit available in Form 26AS, the department holds back the refund until the issue is resolved. In some cases, the discrepancy leads to adjustments under Section 143(1), reducing or eliminating the refund. Correcting the mismatch early through deductor corrections or revised returns ensures faster refund processing.
Q. How do deductor errors cause TDS mismatches? Deductor errors usually occur during quarterly TDS return filing. These may include incorrect challan numbers, wrong TDS amounts, invalid PAN entries, late filing, or incorrect income reporting. Since the tax department relies on what the deductor uploads, any mistake in their data reflects directly in Form 26AS. Even if the taxpayer has the correct TDS certificate, the system will not grant credit until the deductor submits a corrected return. Coordination with the deductor becomes essential in such cases.
Q. How does TaxBuddy help detect TDS mismatches? TaxBuddy compares the details in Form 26AS, AIS, TIS, and income documents uploaded by users. The system highlights inconsistencies instantly and flags differences in income, challan entries, or TDS amounts. The platform’s AI-driven checks reduce manual review time and provide clear instructions on whether the mistake is on the taxpayer’s side or the deductor’s side. Expert support ensures the correct corrective action is taken, preventing unnecessary notices and delays.
Q. Can a revised return correct a TDS mismatch? A revised return can correct a mismatch when the error lies in the originally filed ITR. Once the deductor’s corrections are reflected in Form 26AS, updating the TDS details in a revised return ensures the return aligns with the department’s records. Revised returns are commonly filed when taxpayers forget to include income entries, enter incorrect TDS values, or claim more TDS than what appears in 26AS at the time of filing.
Q. How to prevent TDS mismatches in the future? Preventive steps include verifying PAN details with employers and financial institutions, reconciling interest income with bank statements, checking Form 26AS every quarter, comparing Form 16 and TDS certificates with department records before filing, and ensuring bank and personal details remain updated. Reviewing AIS and TIS during pre-filing helps catch early discrepancies. Consistent monitoring minimizes the risk of receiving mismatch notices.
Q. Does Form 26AS always show the correct TDS amount? Form 26AS reflects the data submitted by deductors, not the taxpayer. If the deductor uploads incorrect TDS details, Form 26AS will show those incorrect values until the deductor corrects the filing. While Form 26AS is the tax department’s accepted record for granting credit, its accuracy depends entirely on deductor compliance. This makes regular verification important for ensuring smooth tax filing and refunds.
