What is Form 26AS?

Form 26AS is a report which shows all the tax related details for a person on yearly basis. It includes tax deducted at source (TDS); tax collected at source (TCS) and TDS on property sales. From the AY 2023-24, Form 26AS now only shows TDS and TCS related information. Other financial details like interest and investment have been transferred to the AIS. Form 26AS will continue to show all the information for years before 2023-24.

What is the Annual Information Statement (AIS)?

The Annual Information Statement, or AIS provides the details of a person’s financial transactions in more depth than Form 26AS. It includes interest from savings accounts, rent earned, dividends received, sale or purchase of properties or shares, foreign remittances, fixed deposit interest and GST turnover.

AIS shows two values for every transaction, the report value which means the value reported by the third parties such as banks and the modified value which is the value given after the feedback of taxpayer, if any. Taxpayers can check the information and are able to give feedback online if anu details are incorrect. AIS help taxpayers to file correct returns and reduce errors or mismatches.

How is AIS Different from Form 26AS?

The major difference is that Form 26AS only focus on the tax deducted and collected whereas AIS includes many more financial details. AIS gives a full information of a taxpayer’s earnings and money related activities in one place.

What is the Taxpayer Information Summary (TIS)?

TIS is a very simple and clear summary of the information shown in AIS. It gives a category wise summary like salary, interest or dividend income. It shows two values, the value which is calculated by the system after the removal of duplicate data and the value accepted by the taxpayer after checking the details. This final value is used to pre-fill the income tax return which makes the process easier.

Importance of Form 26AS, AIS and TIS

Form 26AS, AIS and TIS helps the taxpayers to check and confirm all their financial details before filing returns. They review these documents carefully and can avoid mistakes, missed income or incorrect tax details. This makes the filling process very simple and decreases the chances of notices or re-checks from the tax department.
