Form 26AS, the Annual Information Statement (AIS) and the Taxpayer Information Summary (TIS) are related income-tax information tools, but they do not serve the same purpose. A taxpayer preparing an income-tax return should understand what each one shows, how the three fit together and why none of them replaces the taxpayer's own books, bank statements and income records.
The Income Tax Department's official AIS FAQ describes AIS as a comprehensive view of information available for a taxpayer before filing the return. It also explains that, from Assessment Year 2023-24 onwards, Form 26AS on the TRACES portal displays only TDS/TCS-related data, while other taxpayer information is available in AIS.
What is Form 26AS?
Form 26AS is the Annual Tax Statement. Under the current framework described by the Income Tax Department, from AY 2023-24 onwards it focuses on TDS and TCS data. It is therefore particularly useful for checking whether tax deducted or collected against the taxpayer's PAN has been reported correctly.
For return preparation, a taxpayer can compare TDS shown in Form 26AS with salary certificates, interest certificates, professional receipts and other supporting records. A mismatch should be investigated rather than solved by simply copying whichever number appears on screen.
What is AIS?
AIS is broader than Form 26AS. The Department says AIS includes information presently available with it and provides taxpayers a facility to give feedback. Its Part A contains general taxpayer information. Part B can include TDS/TCS information, Statement of Financial Transaction information, tax payments, refund information and other information received from various sources.
The practical value of AIS is visibility. It can alert a taxpayer to income or transactions reported by banks, employers, deductors or other reporting entities that may otherwise be missed during return preparation. However, the Department expressly warns that AIS may not contain every transaction relating to a taxpayer. The taxpayer remains responsible for reporting complete and accurate information in the return.
What is TIS?
TIS is the Taxpayer Information Summary contained within the AIS framework. Instead of presenting every information item at transaction level, it provides category-wise aggregated information such as salary, interest or dividend. The Department explains that TIS shows a value processed by the system and a value accepted by the taxpayer or confirmed by the source after considering feedback.
Where applicable, the accepted or source-confirmed value in TIS is used for pre-filling the income-tax return. That makes TIS useful as a return-preparation summary, but it should still be reconciled to source documents before filing.
AIS vs TIS vs Form 26AS: the practical difference
- Form 26AS: use it primarily to verify TDS/TCS information under the current AY 2023-24 onwards framework.
- AIS: use it for a broader transaction-level view of information available with the Income Tax Department and to review or respond to reported information.
- TIS: use it as the category-wise aggregated summary derived from AIS information and feedback, including values that may be used for return pre-fill.
What should you do when AIS information is wrong?
AIS provides an online feedback facility. The Department's FAQ explains that AIS can show both the value originally reported and a modified value after considering taxpayer feedback or source confirmation. If an entry belongs to another person, is duplicated, has an incorrect amount or otherwise needs correction, the taxpayer should use the available feedback mechanism rather than silently ignoring the discrepancy.
Feedback does not eliminate the need for evidence. Keep the bank statement, contract note, interest certificate, Form 16 or 16A, sale document or other record that supports the position taken in the return.
Example: bank interest differs across records
Assume AIS shows bank interest of ₹48,000, while the taxpayer's bank certificates and ledger show ₹52,000. The correct approach is not to cap taxable interest at ₹48,000 merely because AIS displays that amount. The taxpayer should investigate the difference and report complete and accurate income based on the applicable tax rules and reliable records. AIS is an information source, not a legal ceiling on taxable income.
Example: duplicate transaction in AIS
Suppose the same securities transaction appears twice in AIS because of reporting or processing issues. The taxpayer should compare the entries with broker statements and other records and use AIS feedback where appropriate. TIS may reflect processing or accepted values, but the final return should still be supported by the taxpayer's actual transaction records and tax computation.
A practical pre-filing reconciliation checklist
- Download or review Form 26AS: reconcile TDS/TCS credits with certificates and income records.
- Review AIS transaction categories: scan salary, interest, dividend, securities, SFT and other relevant information for missing or unfamiliar items.
- Review TIS: compare category totals and pre-fill values with your own computation.
- Investigate mismatches: identify whether the difference comes from timing, duplication, incorrect reporting, missing income or an incorrect PAN-linked entry.
- Submit AIS feedback where appropriate: do not use feedback merely to force AIS to match a desired tax result.
- Reconcile with primary records: bank statements, books, broker reports, Form 16/16A, invoices and investment records remain important.
- File the return from the complete tax position: the Department specifically states that taxpayers are expected to report complete and accurate information even if a transaction is not presently displayed in AIS.
Common mistakes to avoid
- Assuming Form 26AS still contains every category of tax and financial information that appeared there historically.
- Treating AIS as a complete substitute for books, bank statements and source documents.
- Copying TIS pre-fill values without reconciling them to actual income and transactions.
- Ignoring a wrong AIS entry without considering the portal's feedback facility.
- Assuming income is not taxable merely because it does not appear in AIS.
Practical takeaway
Use the three tools in sequence: Form 26AS for TDS/TCS verification, AIS for the broader information trail and transaction review, and TIS for the aggregated summary used in return preparation and pre-fill where applicable. Then reconcile all three with primary records. The safest filing position is not “whatever AIS says”; it is the complete and accurate tax position supported by evidence.
