AIS, TIS and Form 26AS: The Three-Way Reconciliation Before Filing an Income-Tax Return

By CA Nikhil Gupta · 20 July 2026

AIS is a broad information statement, TIS is a processed category summary and Form 26AS remains central to tax-credit and specified information. None of them replaces the taxpayer's books, bank records and legal analysis.

The prefilled return has reduced data entry but not taxpayer responsibility. Information may be duplicated, reported under a joint holder, classified in the wrong year or shown at gross value where taxable income requires a different computation.

A strong filing process reconciles the information statements to source documents, records feedback and explains every material difference.

What AIS contains

AIS displays reported information for a financial year, including TDS and TCS, specified financial transactions, tax payments, demand or refund information and other categories made available by the department. It shows reported and, where relevant, modified values after feedback.

The same economic event can appear through more than one reporting channel. A securities sale may be reported by an intermediary while related TDS or tax payment appears elsewhere.

What TIS does

TIS presents information-category summaries derived through processing of AIS data and taxpayer feedback. It is designed to support a cleaner high-level view and return prefilling.

A processed value is not necessarily the final taxable value. For example, gross sale consideration for securities is not capital gain; cost, holding period and transfer expense must be applied.

What Form 26AS confirms

Form 26AS remains a key source for TDS, TCS, advance tax, self-assessment tax, refund and specified information under the current framework. A tax credit should be claimed only when it belongs to the taxpayer and period and is reflected or otherwise lawfully supported.

Where the deductor used the wrong PAN, amount or year, the preferred correction is through the deductor's statement rather than an unsupported return claim.

Common mismatch patterns

Frequent issues include previous-employer salary omitted or duplicated, bank interest reported gross while books use accrual, joint-property values assigned to one PAN, securities sale value mistaken for gain, mutual-fund redemption appearing without cost, duplicate SFT records, and TDS shown in a different year.

Foreign income and assets may not be fully reflected. Absence from AIS does not make taxable income exempt.

The reconciliation control

Export AIS and tax-credit data, prepare a category-wise workbook and tie each line to Form 16/16A, bank certificate, broker capital-gain statement, property document, foreign statement or books. Mark each item as matched, timing difference, duplicate, not belonging, information-only or requiring correction.

Retain evidence of feedback and deductor follow-up. The return position should be based on law and source records, with a short note for every material variance from AIS/TIS.

Practical Checklist

• Download AIS/TIS and Form 26AS after the reporting cycle is reasonably complete.
• Match each material line to source evidence.
• Convert gross transaction values into taxable income using the relevant rules.
• Submit accurate AIS feedback for duplicates or non-belonging items.
• Pursue deductor correction for missing or incorrect tax credit.
• Retain the reconciliation and evidence with the filed return.

Article-Specific Q&A

Is every amount in AIS taxable income?

No. AIS may show gross sale value, transfers, purchases or information-only items. Taxable income must be computed under the applicable provision.

What is the difference between AIS and TIS?

AIS provides detailed information and feedback functionality. TIS presents processed category summaries used for a consolidated view and prefilling.

Can I claim TDS shown in Form 16 but missing from Form 26AS?

First seek correction from the deductor and retain evidence. Credit entitlement and processing can become contentious when the deductor has not correctly reported or deposited tax.

Does AIS feedback automatically delete the original entry?

Feedback records the taxpayer's response and can influence modified values, but the source reporter's record may remain until corrected. Preserve evidence.

Why does AIS show the full mutual-fund redemption?

Information reporting can capture gross consideration. Capital gain requires cost, holding period and tax classification.

Do I need to report foreign income if it is absent from AIS?

Yes, where taxable and reportable. AIS is not a complete legal safe harbour, and foreign-asset schedules can have separate requirements.

When should I download the statements?

Review them early, then refresh before filing because deductors and reporting entities may submit or revise data over time.
