Understanding the financial year (FY) in India
In India, a financial year (FY) is a 12-month period that begins from April 1 of every calendar year and lasts till March 31 of the following year. It is basically the time frame during which individuals, businesses or any entity earns income. All incomes like salary, rent, interest, business income, capital gains, etc, earned during this period become taxable.

Importance of the financial year for accounting & planning
Reporting income and calculating taxes
All forms of income, salary, business profits, investment returns or rental earnings must be reported for the financial year. This fixed period helps the government compute your taxable income, apply relevant deductions and determine your total tax liability accurately.
Importance of filing deadlines
Once the financial year ends, you are required to file your Income Tax Return (ITR) by the due date, generally July 31 (unless extended). Late filing may result in penalties, interest, and potential scrutiny.
Claiming deductions and tax planning
Tax-saving investments and deductions such as those under Section 80C, HRA or home loan interest must be made within the financial year.
Role in budgeting and government planning
The financial year serves as the foundation for the government’s annual budget, which influences tax rates, public expenditure and policy decisions. Businesses also follow this period to prepare financial statements, plan cash flows and make strategic investments.

Definition of assessment year
In India, the concept of an assessment year developed alongside its income tax framework. Its core purpose is to evaluate the income earned during a particular financial year and apply the appropriate taxes in the following year.
The Assessment Year (AY) always comes immediately after the Financial Year (FY). It is the period during which the Income Tax Department examines the income you earned in the preceding FY and determines the tax payable.
The interrelation: FY precedes AY
There is a simple connection between FY and AY. The income that you earn in the FY is assessed in the AY. This interrelation is the core of the assessment year vs financial year concept. So, if you earned income between April 2024 and March 2025, you report and pay applicable taxes in AY 2025–26. Because the assessment happens after the income is earned, the FY must precede the AY.
Financial year vs assessment year: Key differences and examples
| Financial year | Assessment year |
| The year in which a person actually earns the income. | The year in which income earned during a financial year is evaluated and taxed. |
| Runs from April 1 to March 31, different from a standard calendar year. | Also runs from April 1 to March 31, but it always follows the financial year. |
| Tax planning and investments to reduce tax liability can be done during this year. | After the financial year ends, income is reviewed and tax becomes payable. |
Illustrative examples of FY and AY
Example 1: Salary income
If a salaried person earns income from April 1, 2024, to March 31, 2025.
That period is FY 2024–25
They will file their ITR in AY 2025–26
Example 2: Mutual fund capital gains
Suppose an investor redeems units of a mutual fund in December 2024:
This falls under FY 2024–25
The capital gains will be reported in AY 2025–26

Why this distinction is crucial for your income tax filing
If a taxpayer mixes up or interchanges the Financial Year (FY) and the Assessment Year (AY) while reporting income in the income tax return, it may be treated as incorrect filing.
Since income tax forms are always filed for the Assessment Year, taxpayers must be careful about selecting the correct AY. This is one of the primary reasons understanding the assessment year vs financial year matters.

How FY and AY affect mutual fund investments
For both capital gains and dividends, mutual fund taxation is linked to the year of earning the income. Here is how FY and AY connect with mutual fund transactions:
Capital gains
Capital gains from mutual funds arise on redemption. The date of redemption decides the Financial Year.
Example:
Redemption date: January 2025
Falls in FY 2024 – 25
Tax filing happens in AY 2025 – 26
Dividends
If an investor receives dividends from mutual funds, the income is counted in the FY in which it is received and is then reported in the corresponding AY.
ELSS (Equity linked savings scheme) investments
Investments in ELSS may offer tax deductions under Section 80C as per current regulations. To claim this deduction the investment must be made within the specific FY and the tax benefit is claimed in the AY that follows.

FAQs
Is the Financial Year the same for all entities in India?
Yes. The Financial Year in India runs from April 1 to 31 March 31.
What is the current Financial Year and its corresponding Assessment Year?
The current Financial Year is 2025-26 and the corresponding Assessment Year is 2026-27. This means income earned between April 1, 2025, and March 31, 2026, will be assessed and taxed in AY 2026–27.
Why do income tax forms ask for the Assessment Year and not the Financial Year?
ITR forms are filed after income is earned. Since the evaluation and taxation happen later, tax forms require the Assessment Year.
What happens if I accidentally mention the wrong AY while filing my ITR?
If an incorrect AY is selected, the income details may not match pre-filled information or TDS records. This may require revising the return or responding to notices from the Income Tax Department.
How does understanding FY and AY help in tax-saving investments like ELSS?
ELSS investments made within a Financial Year may be considered for tax deductions under Section 80C of the Income Tax Act, 1961. Knowing the exact FY helps ensure the investment falls within the correct deduction period.
