How to Check and Correct Errors in Your AIS and Form 26AS

Find the source of an AIS or Form 26AS mismatch, then use the right route: AIS feedback, a deductor or reporting-entity correction, challan verification, revised return, or eligible CPC rectification.

First identify where the mistake sits: in an AIS item, a deductor’s TDS statement, another reporting entity’s report, a tax-payment credit, or your filed income tax return. The correction route depends on the source. AIS feedback records your response to information shown in AIS; it does not, by itself, amend the source entity’s filing. A TDS reporting error generally needs to be corrected by the deductor, while a return error must be handled through the applicable revised-return or rectification process.

What AIS and Form 26AS show—and why they may differ

The Annual Information Statement (AIS) is broader than Form 26AS. The Income Tax Department describes AIS as an extension of Form 26AS and includes examples such as savings-account and deposit interest, dividends, rent, securities and property transactions, foreign remittances, and GST turnover. AIS also lets you submit feedback on an information item. Its Taxpayer Information Summary (TIS) presents aggregated information by category; the department says derived TIS information may be used to prefill a return, where applicable.

Form 26AS is principally relevant for tax-credit details, including tax deducted or collected at source and tax payments. Some transaction and tax-payment information that taxpayers may previously have looked for in 26AS is now available through AIS. The two statements therefore need not display identical categories. Check both for the financial year relevant to the transaction rather than assuming one statement contains everything.

A figure appearing in AIS is not automatically an amount you should copy into your return. Check what the entry describes, which financial year it relates to, who reported it, and whether the transaction belongs to you. Likewise, do not claim a tax credit simply because you believe tax was paid or deducted: confirm the credit against Form 26AS and correct the underlying record if it is absent or wrong.

Choose the correction route based on where the error originated

What appears wrong Who generally needs to act What to do
An AIS item is incorrect, unfamiliar, or attributed to you in error You, for AIS feedback; the reporting source, if its source report is wrong Submit the relevant feedback in AIS, then contact the source identified in the item if the underlying report needs correction.
TDS is missing or incorrect in Form 26AS The employer, bank, tenant, buyer, or other deductor responsible for the deduction Ask the deductor to check the details and file a revised TDS statement if necessary.
An SFT or other third-party report is incorrect The bank, broker, registrar, or other reporting entity shown in AIS Ask that entity to verify and correct or delete its report as appropriate.
A paid advance-tax or self-assessment-tax credit is missing You first verify the challan; the appropriate tax-payment or portal support route may be needed if details are correct Compare the challan serial number, tax type, year, date, and PAN with your receipt before raising the issue.
Your filed return contains an error You, through the return process that applies to its filing and processing status Use an eligible revised return if the return has not been processed and revision is available; consider CPC rectification only for an eligible mistake apparent from the record in an order or intimation.

These routes address different records. An AIS response does not replace a deductor’s revised TDS statement, and a source-report correction does not itself revise your return. If more than one record is wrong, you may need to pursue more than one route.

Check the right year and supporting documents first

  1. Sign in to the Income Tax e-Filing portal. Open Services → Annual Information Statement (AIS), select the financial year that matches the item, and open the AIS.
  2. Inspect the item, not just the total. Note its description, reported amount, and information source. Download or retain the statement so you can refer to the original entry and its details. The AIS FAQ lists PDF, JSON, and CSV download options.
  3. Compare it with independent records. Depending on the item, use bank interest certificates, salary and TDS records, challan receipts, broker statements, sale documents, or other records that show what actually happened.
  4. Review Form 26AS as well. Compare TDS/TCS entries and challan amounts with your records. For missing advance-tax or self-assessment-tax credit, check the challan serial number and PAN, along with the tax type, year, and date shown on the receipt.
  5. Decide which record needs changing. An incorrect AIS description or attribution, a source entity’s incorrect filing, and an error in your ITR are separate problems. Identify each one before submitting a request.

Keep the financial year straight throughout. A statement entry, a tax payment, a TDS quarter, and a return or order may refer to different periods or labels. Use the year and transaction details shown on the relevant document rather than relying on a similar-looking amount alone.

Submit feedback on an incorrect or unfamiliar AIS item

Use AIS feedback to record your view of an information item—for example, that a reported amount is incorrect or that the information does not relate to you. The feedback process records the taxpayer’s response and can show reported and modified values; it should not be treated as confirmation that the bank, employer, broker, or other reporting entity has changed its filed information.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  1. Log in to the e-Filing portal and select Annual Information Statement (AIS) under Services.
  2. Open the AIS tab, select the relevant financial year, and open the AIS tile.
  3. For the active entry, select Optional in the Feedback column, choose the feedback option that best fits the issue, provide any requested details, and submit.
  4. Check the item after submission. Confirm that the feedback is displayed, compare the reported and modified values, and review Activity history.
  5. Download and save the acknowledgement receipt. Keep it with the statement and the documents supporting your response.

Portal labels can change, so follow the current wording on the screen if it differs from these instructions. The department’s AIS FAQ says an acknowledgement receipt can be downloaded and that email and SMS confirmations are sent. Retain your own copy rather than relying only on a notification.

Ask the source to correct TDS or other reported information

Missing or incorrect TDS

If TDS is missing from or incorrectly shown in Form 26AS, contact the party that deducted it. Depending on the payment, that may be your employer, bank, tenant, buyer, or another deductor. Provide the relevant financial year or period and ask it to check your PAN, the amount, quarter, and statement details. The Income Tax Department’s mismatch guidance says the employer or deductor needs to file a revised TDS statement to correct its reporting.

Keep the deductor’s response and any evidence it provides that a correction statement was filed. Until the credit appears in Form 26AS, do not claim a credit that is absent from that statement. If the deductor says the statement is correct, compare its details with your own salary, payment, and tax records before deciding what to dispute next.

Incorrect SFT or another third-party item

For an incorrect Statement of Financial Transactions (SFT) or other third-party entry, use the source name shown in AIS to identify the reporting institution. Contact that bank, broker, registrar, or other entity, explain the specific entry, and ask it to verify the report and submit the required correction or deletion. The department’s SFT guidance places correction or deletion of a submitted transaction report with the reporting entity.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

If you dispute that the transaction belongs to you, include the relevant facts and supporting documents in your communication with the source and use AIS feedback to record your disagreement. Keep both records: your AIS feedback acknowledgement and the source entity’s correspondence. A feedback entry alone does not establish that the source has amended its report.

Missing tax-payment credit

Before raising a missing-credit issue, match the tax-payment receipt against the entry in Form 26AS. Check the challan serial number, tax type, assessment or tax year shown, payment date, and PAN. If one of those details was entered incorrectly, the discrepancy may need to be resolved through the applicable payment or portal process; if they match, retain the receipt and use the department’s relevant support or grievance route.

Decide whether to revise the return or seek rectification

A mismatch in AIS does not automatically mean your filed income tax return is wrong. First establish whether the item belongs to you, falls in the relevant year, and has the tax treatment you believe applies. Then check the status of the return and any order or intimation.

If the filed return has not been processed

If the ITR itself needs correction and it has not been processed, the department’s mismatch guidance points taxpayers to a revised return when revision is available and the taxpayer is eligible. A revised return changes the return; AIS feedback does not. Check the current portal guidance for the applicable filing window and eligibility rather than assuming that revision is always open.

If there is an eligible order or intimation

CPC rectification is for a mistake apparent from the record in an eligible order or intimation. It is not a general substitute for revising a return or a way to introduce new income, a new exemption, or a new deduction. The CPC guidance distinguishes among requests to reprocess a case where correct particulars were furnished but not considered, eligible corrections to return data, and corrections for TDS/TCS or challan tax-credit mismatches.

For a tax-credit mismatch request, re-enter the relevant schedules and do not claim a credit that does not appear in Form 26AS. Select the type of rectification that matches the actual issue; a request to reprocess, a return-data correction, and a tax-credit correction address different circumstances.

The CPC FAQ describes a four-year limit counted from the end of the financial year in which the relevant intimation or order was passed. It also describes an Assessing Officer route in some cases where CPC rectification is unavailable or the matter has moved beyond CPC. The applicable Act, year, order, and remedy can affect the next step, so check current portal guidance or seek qualified tax advice for a consequential or time-sensitive case.

Common mistakes that delay a correction

  • Using the wrong financial year: An amount can look familiar while belonging to another year. Open the year shown in the source record and match the transaction date before responding.
  • Treating AIS feedback as a source correction: Feedback records your disagreement. It does not instruct a bank, employer, broker, or other reporting institution to amend its filed statement.
  • Claiming unavailable TDS: A salary slip or deduction certificate is useful evidence, but the credit should not be claimed when it is absent from Form 26AS. Ask the deductor to correct the statement first.
  • Contacting the wrong party: The taxpayer cannot edit a bank’s SFT or an employer’s TDS statement. Use the source name shown with the AIS item and direct the correction request there.
  • Choosing rectification for a new claim: Rectification addresses an apparent error in an eligible order or intimation. It is not a route for adding a previously omitted income source, exemption, or deduction.
  • Saving only a screenshot: Keep the downloadable statement, acknowledgement receipt, correspondence, and reference numbers. These establish what was reported and when you acted.
  • Publishing sensitive documents: Never place PAN, account numbers, challan details, or complete tax documents in a public forum while asking for help.

  1. Write down the exact item, amount, financial year, source name, and statement in which it appears.
  2. Compare the entry with the document that should exist for that transaction: a bank certificate, salary record, broker statement, sale document, or challan receipt.
  3. If the AIS entry itself is disputed, submit feedback and download the acknowledgement.
  4. If the source filing is wrong, send the source institution a precise correction request and ask for evidence of its revised statement or report.
  5. If TDS or tax payment remains absent from Form 26AS, do not claim the missing credit; retain proof and use the appropriate support route.
  6. If your ITR is wrong, check whether it is unprocessed and eligible for revision. If an order or intimation exists, check whether the issue is an eligible CPC rectification.
  7. Record every submission, reply, ticket, grievance, and reference number in a dated timeline.

Frequently Asked Questions

How do I correct an error in AIS?

Open the relevant financial year in Services → Annual Information Statement, select Optional in the item’s Feedback column, choose the applicable response, provide the requested details, and submit. Check the modified value and Activity history, then download the acknowledgement. If the underlying report is wrong, also ask the information source shown in AIS to correct its filing.

AIS shows income or a transaction that is not mine. What should I do?

Verify the year, description, amount, and source. Submit AIS feedback stating that the information does not relate to you, preserve the acknowledgement, and contact the named bank, broker, registrar, employer, or other reporting entity with supporting facts. Feedback records your disagreement; the source must correct or delete its own report.

My TDS is missing from Form 26AS. Can I claim it anyway?

Do not claim a tax credit that is absent from Form 26AS. Contact the employer, bank, tenant, buyer, or other deductor, ask it to verify your PAN, amount, quarter, and statement details, and request a revised TDS statement. Keep proof of the request and check 26AS again.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

What is the difference between AIS feedback and correcting a TDS statement?

AIS feedback records your response to information displayed in AIS. It does not amend the deductor’s filing. A TDS discrepancy must generally be corrected by the employer or other deductor through a revised TDS statement, after which the corrected credit should appear in Form 26AS.

Should I revise my return or file rectification for a tax-credit mismatch?

If the filed return has not been processed and revision is available, use an eligible revised return. Rectification applies to an apparent mistake in an eligible order or intimation. CPC guidance separately distinguishes reprocessing, return-data correction, and TDS/TCS or challan-credit correction. Do not use rectification to add new income, exemptions, or deductions.

What details should I check when advance tax or self-assessment tax is missing?

Compare the receipt with Form 26AS, including the challan serial number, tax type, assessment or tax year, payment date, and PAN. Keep the receipt. If the details match but the credit is still absent, use the department’s applicable support or grievance route.

How long is the CPC rectification window?

The CPC FAQ describes a four-year limit counted from the end of the financial year in which the relevant intimation or order was passed. The applicable Act, order, year, and remedy still matter, and some cases may require an Assessing Officer route.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Where can I escalate an AIS or Form 26AS problem?

For AIS issues, use e-Filing → AIS tab → AIS Portal → Help → Raise/View Ticket Status. For Form 26AS or TDS-statement queries, use the current TRACES support channel. You can also submit a logged-in grievance through Grievances → Submit Grievance and retain the acknowledgement number. Verify phone numbers and hours on the current department portal.

The Bottom Line

Start with the exact year, item, source, and supporting document. Use AIS feedback for the information shown there, ask the deductor or reporting institution to correct its own statement, verify challans before disputing missing tax credits, and choose a revised return or CPC rectification only after checking processing status and eligibility. Save every acknowledgement and reference number, and protect your PAN and account details.
