TDS Credit Mismatch: Fix Form 26AS Errors Before ITR Filing

A TDS credit mismatch can turn a routine ITR filing into a refund delay or tax demand. The Centralised Processing Centre, or CPC, checks your TDS claim mainly against Form 26AS, so even a small reporting error can affect your final tax computation.

For FY 2025-26, relevant to AY 2026-27, taxpayers should reconcile Form 26AS, AIS, TIS and Form 16 or Form 16A before filing the Income Tax Return. This is especially important for salaried employees, FD investors, freelancers, professionals and property sellers.

TDS credit mismatch: why Form 26AS matters

Form 26AS is the tax credit statement linked to your PAN. It shows tax deducted at source, or TDS, tax collected at source, or TCS, and other tax credit details reported to the Income Tax Department. You can access it through the Income Tax e-filing portal via TRACES.

When you file your ITR, CPC validates the TDS amount claimed in the return against Form 26AS. If your ITR shows higher TDS than Form 26AS, CPC may reduce your refund, raise a demand, or issue an intimation under Section 143(1).

This does not always mean the taxpayer made a mistake. Often, the deductor, such as an employer, bank, tenant, buyer or client, may have delayed filing the TDS return or quoted the wrong PAN. But until the correction appears in Form 26AS, the credit may not be allowed during ITR processing.

For AY 2026-27, taxpayers should continue using Form 26AS as the key document for TDS credit. If there are references to future changes such as renumbering of forms, verify them with the official Income Tax portal before relying on them.

Form 26AS vs AIS vs TIS: key TDS credit differences

Many taxpayers get confused because the same transaction may appear differently across Form 26AS, AIS and TIS.

Form 26AS is the primary tax credit record. It is used to verify TDS and TCS credits. AIS, or Annual Information Statement, is broader. It includes salary, interest, dividends, securities transactions, mutual fund activity, property transactions, foreign remittances, tax payments and TDS or TCS details. TIS, or Taxpayer Information Summary, is a processed summary of AIS values used for pre-filled ITR data.

Form 16 is issued by the employer for salary TDS. Form 16A is issued by banks, companies or other deductors for non-salary TDS. These certificates are useful evidence, but they do not override Form 26AS.

The rule is simple. Use Form 26AS to claim TDS credit. Use AIS and TIS to verify income reporting. Use Form 16 and Form 16A to cross-check what the deductor says it has deducted.

Common TDS credit mismatch reasons in AY 2026-27

A TDS credit mismatch usually happens due to reporting, timing or data entry issues. Some of the most common reasons are:

• The deductor has not filed the quarterly TDS return, such as Form 24Q for salary or Form 26Q for non-salary payments.
• The TDS return has been filed but is still under processing, causing a time lag before credit appears in Form 26AS.
• The deductor quoted the wrong PAN, so the credit does not reflect under your PAN.
• The deductor reported the wrong assessment year or financial year.
• The TDS amount, challan details or section code was entered incorrectly.
• Form 16 or Form 16A was issued, but the deductor’s TDS return was not correctly filed.
• AIS shows a TDS entry, but Form 26AS has not yet reflected the processed credit.
• The taxpayer entered the wrong TAN, amount or duplicate TDS entry in the ITR.

For example, if your bank deducted ₹5,000 TDS on FD interest in March 2026 but did not file or correctly process the quarterly TDS return, the amount may not appear in Form 26AS for AY 2026-27. In that case, you must ask the bank to correct the return on TRACES.

TDS credit reconciliation checklist before ITR filing

Before submitting your return, download the latest Form 26AS and AIS from the Income Tax portal. Do not rely only on old Form 16 copies or bank certificates.

Start with Form 26AS. Check every entry by deductor name, TAN, section, quarter and amount. Match salary TDS with Form 16 Part A. Match FD interest, professional fees, rent, commission or other payments with Form 16A. If you sold property, check TDS under Section 194-IA and ensure the buyer has correctly reported your PAN.

Next, review AIS from the Annual Information Statement section. If AIS shows duplicate, incorrect or denied information, submit feedback. Then check TIS to see whether processed values are aligned with your income computation.

While filling the ITR, enter TDS exactly as reflected in Form 26AS. Match TAN, amount and assessment year. Do not claim TDS that appears only in AIS but not in Form 26AS. If the ITR deadline is close and a deductor correction is pending, file with the credit available in Form 26AS and consider rectification later after the correction reflects.

If you have already filed the return and CPC has processed it with a lower refund or tax demand, compare the intimation under Section 143(1) with Form 26AS. If Form 26AS has updated after filing, you may file a rectification request under Section 154 with supporting details.

What this TDS credit mismatch means for you

Ignoring a TDS credit mismatch can block your refund, create an avoidable tax demand, and lead to repeated follow-ups with the department or deductors. The issue becomes more serious when large credits are involved, such as property sale TDS, professional fees, rent payments or multiple bank deposits.

Salaried taxpayers should reconcile Form 16 with Form 26AS as soon as the employer issues the certificate. Freelancers and consultants should track TDS under Section 194J client-wise. Senior citizens and FD investors should verify bank TDS carefully, especially if multiple branches or deposits are involved.

The practical takeaway is clear. Before filing ITR for AY 2026-27, treat Form 26AS as the final checkpoint for TDS credit. Use AIS and TIS for wider income reconciliation, but claim only verified TDS. If the mismatch is large, involves several deductors, or has resulted in a notice, consult a Chartered Accountant before responding.
