The assessment year is the fiscal year in which tax calculations are performed, serving as the period during which income tax liability is evaluated. Spanning from April 1st to March 31st, it starts on the first financial day following the commencement of the financial year. During this timeframe, taxpayers must submit their returns to qualify for available tax benefits or deductions.

A financial year, alternatively referred to as a fiscal year, spans twelve months and serves as the accounting and taxation period for governments and businesses. Commencing on April 1 of a given year and concluding on March 31 of the following year, it involves meticulous tracking of all income and expenses. The purpose is to ascertain the overall profit or loss and determine the corresponding tax obligations. Individual taxpayers are also impacted by the financial year, receiving their Notice of Assessment from the taxation authority at its onset. This document outlines any alterations to tax obligations compared to previous years, enabling individuals to claim eligible deductions or credits.

Why is there an Assessment Year specified in an ITR Form? The Assessment Year (AY) section in the Income Tax Return (ITR) form specifies the fiscal year to which the taxpayer's reported income corresponds. Essentially, the assessment year signifies the time frame during which any income or gains accrued by the taxpayer need to be disclosed to the Income Tax Department. In India, the financial year spans from April 1 to March 31 of the subsequent calendar year. Consequently, any income earned within this period must be declared in the corresponding assessment year. For instance, if an individual earns income from April 2022 to March 2023, their tax return for that period would fall under AY 2023-24.

Given that individuals may have both ongoing and new investments in a fiscal year, it becomes crucial to differentiate between existing and recent investments in the ITR form. Therefore, the AY section offers clarity regarding which assets and liabilities should be included in a specific tax return filing. It's important to note that even though the Assessment Year on an ITR form aligns with the current financial year, an individual's taxable income may span multiple assessment years. For instance, if someone earns income between April 2019 and June 2020, their income would be taxable under both AY 2020-21 and 2021-22.


Although closely connected, an assessment year and a financial year have different roles. The financial year pertains to the duration when income is earned and expenses are accrued. In contrast, the assessment year is concerned with evaluating and taxing the income earned in the previous financial year. A clear understanding of the differences between an assessment year and a financial year is essential for individuals and companies to effectively handle tax obligations and plan their finances.
