Why You Must Check All Three Before Filing
Filing your Income Tax Return for Assessment Year 2026-27 (Financial Year 2025-26) without cross-checking AIS, TIS, and Form 26AS is a common source of tax-credit mismatches, defective returns, and follow-up notices from the Income Tax Department. Each of these three statements serves a distinct purpose, and the information in one may not fully match the others.
The Income Tax Department itself encourages taxpayers to verify all available information before filing. A mismatch between the TDS you claim and what the department has on record can lead to your tax credit being disallowed, resulting in additional tax demand plus interest. Checking all three statements before you file is the single most effective step to avoid these problems.
What Is the Annual Information Statement (AIS)?
The Annual Information Statement (AIS) is a comprehensive view of taxpayer information available on the Income Tax e-Filing portal. According to the department, AIS is meant to:
- Display complete information to the taxpayer before return filing
- Facilitate feedback from the taxpayer on the information displayed
- Encourage voluntary compliance
- Enable prefilling of returns where applicable
AIS contains the following categories of information:
- General information about the taxpayer
- TDS/TCS details as reported by deductors and collectors
- Statement of Financial Transactions (SFT) data reported by specified entities
- Taxes paid including advance tax, self-assessment tax, and other direct tax payments
- Demand and refund information
- Other information as available with the department
AIS also allows taxpayers to submit feedback if any entry is incorrect, duplicated, or not relates to them. This feedback mechanism is an important tool for resolving discrepancies before you file.
What Is the Taxpayer Information Summary (TIS)?
The Taxpayer Information Summary (TIS) is the category-wise aggregated summary available within the AIS section on the portal. In the department's own wording, TIS shows processed value and derived information, and derived information may be used for prefilling where applicable.
Because TIS aggregates the detailed entries in AIS into summary totals by category (such as salary, interest, dividend, TDS, and so on), it provides a quick snapshot that is useful for cross-verification. However, the processed value shown in TIS is based on the department's processing of the underlying data, and the taxpayer should still verify against their own records and Form 16/16A/16B/16C.
What Is Form 26AS?
Form 26AS is the practical tax-credit statement that taxpayers use for TDS/TCS reconciliation and tax-credit verification. It continues to serve as the primary reference for matching TDS and TCS entries against what deductors and collectors have reported to the department.
Official portal guidance states that information such as advance tax and self-assessment tax payments, refund details, SFT transactions, and certain default-related details that were earlier available in Form 26AS are now available in AIS. This means Form 26AS today is focused more narrowly on TDS and TCS tax-credit data, while the broader financial information has moved to AIS.
AIS vs TIS vs Form 26AS: Comparison Table
| Feature | AIS | TIS | Form 26AS |
|---|---|---|---|
| Purpose | Comprehensive information display, feedback, voluntary compliance, and prefilling | Category-wise aggregated summary under AIS | Tax-credit statement for TDS/TCS reconciliation |
| Level of detail | Transaction-level detail from multiple sources | Aggregated totals by category | Transaction-level TDS/TCS entries |
| TDS/TCS data | Yes, with deductor details | Aggregated TDS/TCS totals | Yes, full TDS/TCS details |
| SFT transactions | Yes | Aggregated in summary | No (now available in AIS) |
| Advance tax / SAT payments | Yes | Aggregated totals | No (now available in AIS) |
| Refund details | Yes | Aggregated totals | No (now available in AIS) |
| Feedback mechanism | Yes | Based on processed AIS data | No |
| Used for tax-credit claim validation | Supporting reference | Supporting reference | Primary reference (department guidance) |
Which One Should You Trust for What?
Each statement has a distinct role. Using the wrong one for a given purpose can lead to filing errors:
| Purpose | Primary Statement to Use | Why |
|---|---|---|
| Claiming TDS credit in ITR | Form 26AS | Department restricts claimed tax credit to the amount reflected in Form 26AS |
| Checking all reported financial transactions | AIS | Most comprehensive view including SFT, taxes paid, and other information |
| Quick category-wise overview before filing | TIS | Aggregated summary useful for a quick cross-check |
| Submitting feedback on incorrect entries | AIS | Only AIS provides the feedback mechanism for individual entries |
| Verifying advance tax or self-assessment tax payments | AIS | This data is now available in AIS, not Form 26AS |
| Reconciling TCS amounts | Form 26AS + AIS | Cross-check both to ensure consistency |
Be aware that these statements may not always match. AIS may show a TDS entry that is not yet reflected in Form 26AS, or vice versa. When in doubt, rely on Form 26AS for tax-credit claims (as per department guidance) and use AIS to investigate and resolve discrepancies.
Pre-Filing Checklist
Use this checklist before you start filling your ITR for AY 2026-27:
- Download Form 26AS from the Income Tax e-Filing portal. Verify every TDS and TCS entry against your Form 16, Form 16A, and other TDS certificates.
- Review AIS on the portal. Check all sections: TDS/TCS, SFT, taxes paid, demand/refund, and other information. Submit feedback on any entry that is incorrect, duplicated, or does not relate to you.
- Check TIS for the category-wise summary. Compare the processed totals with your own computation of income and tax.
- Compare your income details (salary, interest, dividends, capital gains, rental income, etc.) with the entries in AIS. The department may flag income reported by third parties that you have not declared.
- Verify advance tax and self-assessment tax payments in AIS. Ensure the challan amounts and dates match your bank records and challan receipts.
- Cross-check TDS amounts between Form 26AS and AIS. If there is a difference, identify the cause before filing.
- Ensure PAN is correctly reflected in all deductor reports. A wrong PAN in the deductor's TDS return will cause the credit to not appear in your statements.
- Keep supporting documents ready: Form 16/16A, bank statements, investment proofs, capital gains statements, and rent receipts.
How to Handle Mismatches
Tax-credit mismatches are one of the most common issues taxpayers face. Here is how to handle different scenarios:
Scenario 1: TDS Amount Does Not Match
If the TDS shown in Form 26AS or AIS does not match the TDS certificate (Form 16/16A) or your records:
- Inform the deductor or employer about the discrepancy
- Request the deductor to file a revised TDS return with the correct details
- Once the revised TDS return is processed, the corrected TDS credit should reflect in Form 26AS
- Wait for the updated Form 26AS before filing your ITR, or file with the correct claim and be prepared for potential scrutiny
Scenario 2: TDS Credit Missing from Form 26AS
If the deductor has deducted TDS but it does not appear in your Form 26AS:
- Check if the deductor used the correct PAN
- Contact the deductor and request them to file or revise the TDS return
- You cannot claim TDS credit that is not reflected in Form 26AS, as the department restricts claims to the amount shown in Form 26AS
Scenario 3: Income or Transaction in AIS That Does Not Belong to You
If AIS shows an entry that is incorrect or not yours:
- Submit feedback on the AIS portal against the specific entry
- Select the appropriate reason: information is not correct, information is not related to the taxpayer, information is duplicate, etc.
- The department will process your feedback
Scenario 4: Other Tax-Credit Mismatch After Filing
If you discover a mismatch after filing the return:
- If no intimation under section 143(1) has been received: File a revised return with the correct details
- If intimation under section 143(1) has already been received: You may need to file an application for rectification
Frequently Asked Questions
FAQ 1: Is AIS the same as Form 26AS?
No. AIS is a comprehensive view of taxpayer information covering TDS/TCS, SFT transactions, taxes paid, demand/refund details, and other information. Form 26AS is primarily the tax-credit statement used for TDS/TCS reconciliation. Official portal guidance states that certain details such as advance tax/SAT payments, refund details, and SFT transactions that were earlier in Form 26AS are now available in AIS.
FAQ 2: Can I claim TDS that is shown in AIS but not in Form 26AS?
The department's guidance states that the claimed tax credit in the ITR is restricted to the amount reflected in Form 26AS. If TDS appears in AIS but not in Form 26AS, you should contact the deductor to correct their TDS return so the credit appears in Form 26AS. Claiming credit not reflected in Form 26AS increases the risk of a tax-credit mismatch.
FAQ 3: What is the difference between AIS and TIS?
TIS is the category-wise aggregated summary under AIS. While AIS shows transaction-level details, TIS shows processed value and derived information in summary form. Derived information from TIS may be used for prefilling where applicable.
FAQ 4: What should I do if AIS shows income that is not mine?
You can submit feedback on the AIS portal against the specific entry. Select the relevant reason (information not correct, not related to you, duplicate, etc.). The department will process your feedback. However, keep in mind that AIS may not contain every item relevant to you, so always verify all information independently.
FAQ 5: Do I need to check all three statements before filing?
Yes. Each statement serves a different purpose. Form 26AS is the primary reference for tax-credit claims, AIS provides the most comprehensive view of reported information and allows feedback, and TIS gives a quick summary. Checking all three reduces the risk of mismatches and notices.
FAQ 6: I already filed my return but found a TDS mismatch. What should I do?
If you have not yet received an intimation under section 143(1), file a revised return with the correct details. If the intimation has already been received, you may need to file an application for rectification. In both cases, also contact the deductor to file a revised TDS return.
