AIS/TIS Mismatch: How to Correct Tax Information Before Filing

AIS/TIS Mismatch: Fix Wrong Tax Data
CA Nikhil Gupta·May 2026·4 min readIncome Tax Practical Guides (2025-26)

A mismatch in the Annual Information Statement or Taxpayer Information Summary is a prompt to investigate, not automatic evidence of tax evasion. The correct response depends on whether the source data is duplicated, belongs to another person, uses a different measurement or is accurate but absent from the return.

Finin2min takeaway: Act from primary records, use the official channel and keep a dated evidence trail. A portal message, screenshot, dashboard or verbal assurance is not a substitute for the governing rule and underlying documents.

Current position in plain English

AIS is broad information reportingIt can include interest, dividends, securities, property, foreign remittances, GST-linked data and other reported items. A transaction amount is not always taxable income.
TIS is a processed summaryTIS may show processed and derived values used for pre-filling or risk analysis. It should not replace primary records.
Feedback does not amend the return by itselfSubmitting feedback can help correct source information, but the taxpayer must separately file the legally correct return or response.
Form 26AS remains critical for tax creditTax deducted or collected should be reconciled with Form 26AS and deductor certificates. AIS cannot create a credit that is absent from the tax-credit record.
The 2026 transition changes forms, not the need to reconcileFor tax periods under the new Act, the portal may use new form numbering. Keep year-specific records and select the correct law and tax period.

How to apply the rule

Use the portal statement as a starting point, not a substitute for books and supporting documents. Tax reporting follows the legal character of an amount: a bank credit may be income, a transfer, a loan, a reimbursement or a sale consideration. Label the amount before deciding its tax treatment.

Keep a year-specific working paper. The transition on 1 April 2026 means the filing date alone does not identify the governing statute. Record the income period, the applicable Act, the return or proceeding, the tax credit and the portal service used.

A good compliance file lets another professional reproduce the result. Include the taxpayer’s figure, the department or third-party figure, the difference, the explanation and the evidence reference.

For AIS TIS mismatch correction, first identify the legal or contractual relationship, then separate the amount, event and deadline. Use one chronology across the portal, institution and supporting records. This prevents a correct fact from being submitted under the wrong year, account, policy clause or complaint route.

Practical example

A mutual-fund statement shows ₹12 lakh of redemptions while AIS displays ₹12 lakh as a transaction. The taxable figure is not automatically ₹12 lakh; capital gain depends on cost, holding period, grandfathering or other applicable rules. Reconcile units and cost before filing.

Evidence and document checklist

Common mistakes

Red flags

  • Large unexplained cash, property or foreign-remittance entries
  • A PAN mismatch involving another taxpayer
  • Repeated source correction failures
  • A filed return materially inconsistent with primary records
  • A portal campaign or notice with a near deadline

Escalation route

First correct the underlying record with the reporting entity and submit AIS feedback. For tax-credit mismatch, use the portal’s tax-credit mismatch service and ask the deductor or collector to file a correction. Respond separately to any notice.

When escalating, include the original complaint, acknowledgement, concise chronology, disputed amount, rule or clause relied upon and the exact relief requested. Do not send passwords, PINs, OTPs or unrelated identity documents.

Frequently Asked Questions

Does an AIS mismatch always cause a notice?
No, but unresolved material differences can trigger queries or processing problems.
Can AIS be wrong?
Yes. Source reporting can be duplicated, incomplete or attached to the wrong PAN. Keep proof and submit accurate feedback.
Should I report income not shown in AIS?
Yes, where taxable. The return must reflect law and actual records, not only portal data.
Why is TIS different from AIS?
TIS is a processed summary; AIS contains more detailed reported information and feedback status.
Can I claim TDS shown only in a certificate?
Tax credit normally needs to appear in the official tax-credit record; ask the deductor to correct reporting.
