The financial year (FY) plays a crucial role in taxation, business accounting, and financial planning in India. It is the 12-month period used by businesses and individuals for financial reporting and taxation purposes. Understanding the financial year is essential for taxpayers, investors, and businesses to comply with tax laws, file income tax returns on time, and manage financial records effectively.

In this article, we will explore what a financial year is, its importance, how it differs from an assessment year, its relevance for tax filing, and other key aspects related to it.
 

What is a Financial Year (FY)?

A Financial Year (FY) is the 12-month period used for recording income, expenses, and tax calculations. In India, the financial year starts on April 1st and ends on March 31st of the following year.

For example, the financial year 2024-25 will begin on April 1, 2024, and end on March 31, 2025.

The financial year is crucial for:

  • Tax Filing: It determines the period for which individuals and businesses need to report their income.
  • Accounting & Auditing: Companies prepare balance sheets, profit & loss statements, and financial reports based on the financial year.
  • Budget Planning: Governments and organizations set financial goals and allocate budgets according to the financial year.
     

Financial Year vs. Assessment Year (AY)

The terms Financial Year (FY) and Assessment Year (AY) are often confused. Here’s the difference:

Aspect Financial Year (FY) Assessment Year (AY)
Definition The year in which income is earned The year in which income is assessed and taxed
Duration April 1 – March 31 April 1 – March 31 (of the next year)
Example FY 2024-25 (April 1, 2024 - March 31, 2025) AY 2025-26 (April 1, 2025 - March 31, 2026)

Key Point: Taxpayers file income tax returns for a financial year in the corresponding assessment year.

For instance, if you earned income in FY 2023-24 (April 1, 2023 - March 31, 2024), you will file your Income Tax Return (ITR) in AY 2024-25 (April 1, 2024 - March 31, 2025).
 

Why is Financial Year Important for Indian Taxpayers?

The financial year impacts taxpayers in multiple ways:

1. Income Tax Calculation
Income earned in a financial year is taxed in the following assessment year. Taxpayers must calculate taxable income, claim deductions, and pay taxes accordingly.

2. ITR Filing
The Income Tax Return (ITR) for a financial year must be filed in the corresponding assessment year before the due date (usually July 31 for individuals and October 31 for businesses).

3. Advance Tax Payments
If your total tax liability exceeds ₹10,000, you must pay advance tax in installments during the financial year to avoid penalties.

4. Tax Planning & Investments
Many tax-saving investments like PPF, ELSS, and tax-saving FDs must be made within the financial year to avail deductions under Section 80C.

5. Business Financial Reporting
Companies must prepare profit and loss statements, balance sheets, and financial reports for the financial year, which are used for auditing, tax filing, and investor relations.
 

Tax Filing Deadlines Based on Financial Year

Common Terms Related to Financial Year

1. Previous Year
The previous year refers to the financial year in which income was earned. For tax purposes, it is the same as the financial year.
Example: FY 2023-24 is also the previous year for AY 2024-25.

2. Tax Deducted at Source (TDS)
Employers deduct TDS on salaries based on the financial year and issue Form 16 for tax filing.
