Form 26AS vs AIS vs TIS: The Three Reports Taxpayers Confuse

These reports overlap, but they are not interchangeable and none replaces the taxpayer’s own evidence.

What the taxpayer should understand

• India’s Income-tax Act, 2025 took effect on 1 April 2026. The 1961 Act continues to govern tax years beginning before that date. Therefore, FY 2025–26 and AY 2026–27 remain governed by the 1961 Act, while tax year 2026–27 beginning 1 April 2026 is governed by the 2025 Act. A notice, return, payment or form must be analysed under the law applicable to the relevant tax year and event—not merely the date on which the portal communication is received.
• Form 26AS is central to tax-credit and specified tax information reflected against the PAN.
• AIS provides a broader transaction-level view, including SFT and other information received from reporting entities.
• TIS summarises AIS information category-wise and can reflect processed feedback.
• Income, deduction, exemption and capital-gain computations still require source documents and the applicable law.

The five-point review

Practical example

How to apply the framework

Reconcile report by report instead of selecting the one with the lowest number.

Download copies used for filing. Portal data can change after feedback or reporting-entity correction.

Tax-control workflow

Fix the period, governing Act and portal document

Identify the financial year, assessment year or tax year, the date of the underlying event and the statutory document. A communication received after 1 April 2026 may still concern a year governed by the 1961 Act. Record 26as, ais and tis before preparing the response or return.

Reconcile the portal with primary evidence

Start from contracts, certificates, bank statements, broker or property records, foreign statements and prior filings. Then reconcile AIS, TIS, Form 26AS, the return, tax payments and notices. Portal information is a powerful control but can contain gross values, duplicates, timing differences or reporting-entity errors.

Submit through the correct route and retain proof

Use the specific service—return filing, AIS feedback, e-Proceedings, rectification, refund reissue, Form 67, appeal or grievance—rather than uploading the same explanation everywhere. Preserve the filed form or response, computation, annexures, transaction ID, acknowledgement and subsequent portal status.

Implementation checkpoint

Before closing the task, verify the live portal outcome rather than relying only on a submission message. Confirm whether the return is verified, the feedback is recorded, the tax credit changed, the refund was reissued, the notice response shows a transaction ID, the demand was adjusted or the appeal was registered. Record the next deadline and unresolved amount.

Action checklist

• Download all three reports.
• Match tax credits first.
• Reconcile income and transaction values.
• Investigate duplicates and year differences.
• Prepare a final return bridge.
• Archive filing-date versions.
