The Annual Information Statement and the Taxpayer Information Summary (TIS) have become the most important documents for ITR filing in India.

Most income tax notices today are triggered due to:

AIS mismatch
Wrong reporting
Missing interest income
Incorrect capital gains
Unreported foreign remittances
TDS differences between AIS & Form 26AS

This 2025–26 guide will help you verify everything correctly and avoid notices.

What is AIS 4.0?

AIS is a detailed tax statement that captures all your financial transactions:

Salary, interest, dividends
Stock market transactions
Mutual fund purchases/redemptions
Credit card high-value transactions
Rent received
Property purchase/sale
Cash deposits
Foreign remittances (LRS)
GST turnover
TDS/TCS entries

AIS 4.0 (2025 update) has improved categorisation, source-level reporting, and a new mismatch warning section.

What is TIS?

TIS is a simplified version of AIS.
It shows summary values grouped under:

Salary
Interest
Dividend
Rent
Business turnover
Securities transactions
Other incomes

Important:
Your ITR pre-filled values are taken from TIS, not AIS.

What to Check Inside AIS 4.0

1. Savings account interest mismatch

Banks sometimes report higher interest.
Fix → Use bank passbook/interest certificate.

2. FD/Recurring deposit interest missing

Often under-reported by taxpayers.

3. Stock market buy/sell mismatch

Brokers provide data → Verify using your broker's Tax P&L.

4. Mutual fund capital gains mismatch

Use CAS + AMC capital gains statement.

5. Dividends credited vs declared

Check demat account or broker platform.

6. Rent received (if tenant deducted TDS)

Verify with Form 26QC or 26QB.

7. Property purchase/sale incorrect values

Cross-check your sale deed and TDS statement.

8. Foreign remittance (LRS) reporting

AIS may show turnover based on GSTR-3B.

Business owners must reconcile with books.
