AIS, TIS and Form 26AS are often treated as interchangeable tax statements, but they serve different purposes. For return preparation, the safest approach is not to choose one statement and ignore the others. Instead, understand what each contains, reconcile it with your own records and investigate material differences before filing.
The Income Tax Department's official AIS FAQ explains the current distinction clearly: from AY 2023-24 onwards, Form 26AS available on TRACES displays only TDS/TCS-related data, while other taxpayer information is available through AIS. The Department's AY 2026-27 guidance for salaried individuals likewise lists Form 26AS and AIS separately.
What is Form 26AS?
Form 26AS is the Annual Tax Statement. Under the Department's current guidance, its principal role is to show tax deducted or collected at source. For a taxpayer, it is therefore a key reconciliation document for checking whether TDS or TCS reported against the PAN is appearing in the tax system.
For example, if an employer, bank or customer has deducted tax, the taxpayer should compare the relevant certificate and books or income records with the TDS/TCS information appearing in Form 26AS. A mismatch should be investigated rather than solved by simply copying whichever figure appears higher.
What is AIS?
The Annual Information Statement is broader. The Income Tax Department describes AIS as a comprehensive view of information available for a taxpayer. Its objectives include showing information before return filing, enabling taxpayer feedback, supporting voluntary compliance and facilitating return pre-filling.
AIS can include TDS/TCS information as well as information received through Statement of Financial Transactions and other sources. Current Department guidance also identifies categories such as tax payments, demand or refund information and other information available with the Department. Because AIS is broader than Form 26AS, it can help reveal income or transactions that may otherwise be missed during return preparation.
What is TIS and how is it different from AIS?
TIS, or Taxpayer Information Summary, is a category-wise aggregated summary within AIS. According to the official AIS FAQ, TIS shows values processed by the system and values accepted by the taxpayer or confirmed by the source for categories such as salary, interest and dividend. Where applicable, the accepted or source-confirmed information in TIS is used for pre-filling the return.
Think of AIS as the detailed information statement and TIS as its summarised, category-level view. TIS is useful for a quick reconciliation, but a taxpayer investigating a discrepancy should drill down into the underlying AIS information and source details.
AIS vs Form 26AS vs TIS: practical comparison
- Form 26AS: use it primarily to verify TDS and TCS appearing against the PAN.
- AIS: use it to review the wider information set available with the Income Tax Department and to inspect transaction-level reporting and feedback status.
- TIS: use it as an aggregated category-wise summary that can support pre-filling and high-level reconciliation.
These statements complement rather than replace the taxpayer's books, bank records, invoices, investment statements and other evidence.
Why AIS should not be treated as the return itself
The Income Tax Department expressly cautions that AIS contains information presently available with the Department and that there may be other taxpayer transactions not displayed there. The taxpayer remains responsible for reporting complete and accurate information in the return.
This is a critical compliance point. If professional receipts of ₹10 lakh are correctly recorded in the books but AIS shows only ₹8 lakh because one payer's reporting is absent, the taxpayer should not reduce taxable receipts to ₹8 lakh merely to match AIS. Conversely, if AIS contains an unfamiliar transaction, it should not be ignored without checking the source and underlying facts.
What to do when AIS information is wrong
AIS provides a feedback mechanism. The official FAQ states that taxpayers can submit feedback on active information displayed under TDS/TCS, SFT or Other Information. AIS can then show both the reported value and a modified value after considering taxpayer feedback or source confirmation.
The practical sequence is to identify the source, compare it with documentary evidence, submit the appropriate feedback where the information is genuinely incorrect, and preserve support for the treatment ultimately adopted in the return. Feedback is a correction mechanism for the information statement; it does not remove the taxpayer's responsibility to file the return on the correct facts.
Worked reconciliation example
Assume a consultant's books show professional receipts of ₹18 lakh and bank interest of ₹70,000. Form 26AS shows TDS relating to ₹16 lakh of professional receipts. AIS shows professional receipts reported by multiple payers totalling ₹17 lakh plus the ₹70,000 interest. TIS summarises those information categories.
The correct response is not to choose ₹16 lakh, ₹17 lakh or ₹18 lakh merely because one appears in a government statement. The consultant should reconcile payer-wise invoices, books, bank credits, TDS certificates and AIS entries. If the books correctly establish ₹18 lakh of professional receipts, the return must reflect the complete taxable income even if a payer has not yet reported part of it. If an AIS entry is duplicated or belongs to someone else, the taxpayer should use the AIS feedback facility and retain evidence.
Return-preparation checklist
- Download or review all three views: check Form 26AS, detailed AIS and TIS rather than relying on a single statement.
- Reconcile TDS/TCS first: compare Form 26AS with Form 16, Form 16A and other deduction records relevant to the taxpayer.
- Review AIS category by category: examine salary, interest, dividend, securities or other reported information relevant to the case.
- Investigate differences: trace mismatches to books, bank statements, invoices, investment records or reporting by the source.
- Submit AIS feedback where justified: use the portal's feedback mechanism for incorrect, duplicate or otherwise disputed information.
- Report complete income: do not omit genuine income merely because it is absent from AIS or Form 26AS.
- Preserve reconciliation evidence: retain a working paper explaining material differences between the return and information statements.
Common mistakes to avoid
- Treating AIS and Form 26AS as the same statement.
- Assuming TIS is a substitute for reviewing detailed AIS entries.
- Reporting only income visible in AIS even when books or other records show more.
- Ignoring an incorrect AIS entry instead of investigating it and using feedback where appropriate.
- Claiming TDS solely because income was earned without checking whether the credit is actually reported and available under the applicable tax rules.
Practical takeaway
Form 26AS is primarily a TDS/TCS reconciliation statement, AIS is the broader information statement, and TIS is the aggregated summary within AIS. Use all three as reconciliation tools, not as substitutes for books and supporting records. The final return should reflect the taxpayer's complete and accurate income after differences have been investigated and documented.
