Assessment Year (AY)

Assessment Year (AY) is the 12-month period following a Financial Year (FY) in which the income earned during the previous financial year is assessed and taxed. Taxpayers file their Income Tax Return (ITR) during the assessment year for income earned in the preceding financial year.

Assessment Year (Quick Explanation)

In Indian income tax, income is earned during a Financial Year (FY), but it is evaluated and taxed in the next year known as the Assessment Year (AY). This is why taxpayers file their ITR after the financial year ends.

For example, income earned between 1 April 2024 and 31 March 2025 falls under FY 2024–25. This income will be assessed in AY 2025–26.

The assessment year allows taxpayers to calculate their final annual income after considering salary changes, investments, capital gains, rental income, or other earnings received during the financial year.

Key Points About Assessment Year

• Assessment Year comes immediately after the Financial Year.
• Income earned in FY is taxed in the corresponding AY.
• ITR filing is done during the Assessment Year.
• AY always starts on 1 April and ends on 31 March.
• AY helps taxpayers report complete annual income accurately.
• Both residents and NRIs must select the correct AY while filing ITR.

Example

An NRI earns rental income and capital gains in India during FY 2024–25. The taxpayer will report and file the income tax return for this income in AY 2025–26.

Why Assessment Year Matters

Assessment Year is important because taxpayers cannot accurately calculate their total taxable income until the financial year is completed. It ensures that all income sources, deductions, investments, and gains are properly considered before filing taxes.

Choosing the correct AY while filing an ITR is critical. Selecting the wrong assessment year may lead to filing errors, notices from the tax department, delayed refunds, or return rejection.

For NRIs, understanding AY is especially important when reporting Indian income such as rent, property sales, or investment gains.
