Income Tax Department AIS FAQs
From AY 2023–24 onward, Form 26AS on TRACES primarily displays TDS and TCS information. It is central for verifying whether tax deducted or collected has actually reached the taxpayer’s account, but it does not show every category of income.
AIS is broader. It displays information available to the department from several sources and allows transaction-level feedback. TIS sits within AIS and summarises category-wise processed and accepted or source-confirmed values, which may support pre-filling.
A robust return process starts with the taxpayer’s salary records, bank statements, broker reports, property documents and books. These are then reconciled to Form 26AS for tax credit and to AIS or TIS for information consistency.
| Situation | Meaning | Response |
|---|---|---|
| Form 26AS | TDS and TCS credit information. | Use it to verify tax credit. |
| AIS | Broader transaction-level information. | Use it to identify and challenge reported data. |
| TIS | Category-wise aggregate within AIS. | Use it as a summary, not source evidence. |
| Personal records | Actual income, cost and transaction documents. | Use these to build the return. |
A mismatch can affect income reporting, tax credit or both. Identify which side is wrong before taking action. A deductor correction is usually needed for missing TDS credit; AIS feedback addresses information reporting.
Keep the return reconciliation until the assessment and record-retention risks have passed. Statements can update after filing, and the saved version explains what was available at the time.
The safest approach is to preserve the original record, use the official channel and explain the facts in chronological order. A portal acknowledgement, complaint number or filing receipt is part of the evidence and should be downloaded rather than assumed to remain available forever.
Rules and procedures can change, and the correct action depends on the exact transaction, policy, notice or account. Where money, limitation, criminal allegations, medical causation or a large tax position is involved, qualified professional advice should be obtained before taking an irreversible step.
Tax problems become harder when the filing, notice or payment deadline passes. For this issue, the immediate control is: Download all three for the relevant period. The response should identify the income period first because the applicable Act, return form, terminology and remedy can depend on when the income arose—not merely when the portal communication or payment occurred.
Keep a dated working paper that shows the original figure, the figure reported in the return or statement, the difference and the document that explains it. The minimum starting evidence is Form 16, Form 16A and other TDS certificates. When a number changes after feedback, source correction or a revised statement, preserve both versions so that the chronology remains visible.
Do not confuse a portal update with legal resolution. Acknowledgement of feedback, payment or upload proves submission, but the underlying tax credit, assessment or source report may still need correction. A recurring failure to avoid is Claiming TDS solely from a certificate when it is absent from Form 26AS. Review the final status separately and record the next statutory date.
