Summary: A financial year is a 12-month period used by governments and businesses to track income, expenses, taxes, and performance. This guide explains India’s financial year system, tax terms, and investor relevance.
Quick Overview
- In India, the financial year runs from 1 April to 31 March and is written in formats like FY 2026-27
- It provides a standard period for accounting, taxation, and financial reporting, unlike the calendar year
- Understanding terms like financial year, assessment year, and tax year helps you interpret tax documents correctly
- Businesses use financial years for quarterly results, annual reports, and financial statements
- Investors rely on financial year data to compare performance, track investments, and make informed decisions
Whether you’re filing taxes, reviewing your salary slip, or checking an investment statement, you’ve likely come across terms like FY 2025-26. It’s a financial term that most people encounter regularly but rarely think about until they need to understand what it means.
This guide explains everything you need to know about the financial year in India, when it starts, how it differs from the calendar year, what’s changed with the new tax year, and more.
What is a Financial Year?
Your calendar year may begin in January, but your taxes, investments, and most financial records follow a different timeline.
The government, businesses, and individuals use a 12-month period to record income, expenses, profits, and taxes. In India, that period runs from 1 April to 31 March and is called the financial year.
For example:
- FY 2025-26 runs from 1 April 2025 to 31 March 2026
- FY 2024-25 runs from 1 April 2024 to 31 March 2025
If you started your first job in July 2025, your salary earned from July 2025 to March 2026 will fall under FY 2025-26 because that income was earned during that financial year.
Why Does India Follow April to March Instead of January to December?
India adopted the April-to-March financial year formally during British rule in 1867. After independence, the country retained it because it was already deeply integrated into the tax, accounting, and business framework. The April-to-March cycle also broadly aligned with India’s agricultural and economic activities.
The April-to-March cycle has been followed for decades because government budgeting, tax systems, and business reporting are structured around this period.
This cycle helps:
- The government plan its annual budget and spending
- Businesses prepare financial statements using a common reporting period
- Tax collection and return filing follow a consistent timeline
Using one common financial period makes it easier for the government, companies, banks, and taxpayers to work within the same reporting system.
Financial Year vs Calendar Year
A financial year and a calendar year both span 12 months, but they serve different purposes. While the calendar year is used in everyday life, the financial year is used for taxes, accounting, and many workplace processes.
For example, your company may say your appraisal will take effect from the new financial year or ask you to submit investment declarations before 31 March. In contrast, when people refer to the year 2026 in everyday conversation, they are usually referring to the calendar year.
| Aspect | Financial Year | Calendar Year |
| Definition | A year used to record and report financial activities | A year used for everyday dates and events |
| Duration | 12 months | 12 months |
| Start and end | 1 April to 31 March (in India) | 1 January to 31 December |
| Primary purpose | Tracking income, expenses, taxes, and financial performance | Managing daily life, events, and general planning |
| Example | FY 2025-26 (April 2025-March 2026) | Calendar Year 2025 (January-December 2025) |
Why Does a Financial Year Span Two Calendar Years?
You can take FY 2025-26 as an example.
It starts in April 2025 and ends in March 2026, so it covers parts of two different calendar years. That’s why both years appear in its name.
A simple way to remember it is that the first year tells you when the financial year begins, and the second year tells you when it ends.
Why Do Businesses Follow a Common Financial Reporting Period?
Businesses operate throughout the year, but their financial performance needs to be measured over a fixed period. They need a fixed 12-month period to record their income, expenses, profits, and taxes. This ensures that financial statements are prepared using the same timeline every year.
Following a common reporting period also makes it easier to:
- Compare a company’s financial performance with previous years
- Prepare financial statements in a consistent manner
- Compare businesses across the same reporting period
- Meet tax, regulatory, and compliance requirements on time
Without a standard reporting period, every business could choose different reporting dates, making financial comparisons and compliance much more difficult.
How to Identify the Correct Financial Year?
Once you know that India’s financial year runs from 1 April to 31 March, it’s easy to work out which financial year any date belongs to.
A simple rule to remember is:
- If the date falls between 1 April and 31 December, the financial year starts in that same year
- If the date falls between 1 January and 31 March, it belongs to the financial year that started in the previous year
For example:
- 10 May 2026 falls in FY 2026-27
- 18 November 2026 also falls in FY 2026-27
- 5 February 2027 is still part of FY 2026-27 because the financial year ends only on 31 March 2027
Financial Year vs Assessment Year vs Tax Year
You may notice that older and newer tax documents don’t always use the same terminology. For example, one document might mention Financial Year (FY) 2025-26 and Assessment Year (AY) 2026-27, while another refers to the Tax Year. This is because India’s income tax law changed from 1 April 2026.
Before this change, the income tax system used two terms together. The Financial Year referred to the year in which income was earned, while the Assessment Year referred to the following year in which that income was assessed for tax.
From 1 April 2026, the Income Tax Act, 2025, replaced the term Assessment Year with Tax Year. As a result, older tax records continue to use Assessment Year, while newer records use Tax Year.
| Parameter | Financial Year (FY) | Assessment Year (AY)(for FY 2025-26 and earlier) | Tax Year (for FY 2026-27 onwards) |
| Purpose | Records the period in which you earn your income | The year in which you report that income and file your tax return | Uses one period for both earning income and filing taxes |
| Income earned | During the financial year | Refers to income earned in the previous financial year | During the same tax year |
| When is tax reported? | Income is calculated and recorded during this period | The income tax department assesses the income and tax return for the previous financial year | Income and tax records are linked to the same tax year, so there’s no separate assessment year |
| Example* | FY 2025-26 (1 April 2025-31 March 2026) | AY 2026-27 (return filed for income earned in FY 2025-26) | Tax year 2026-27 (income earned from 1 April 2026 to 31 March 2027) |
*Note: FY 2025-26 and AY 2026-27 refer to the same income under the old system. Tax year 2026–27 refers to a different period, as the new system no longer uses a separate assessment year.
How Investors Use the Financial Year
Once you start investing, you’ll notice that the financial year appears almost everywhere. Whether you’re reading company results, checking a mutual fund statement, calculating investment returns, or following the Union Budget, the reporting period tells you when the reported income, expenses, or transactions occurred.
Knowing the financial year makes it easier to compare investments accurately, keep track of your earnings, and make decisions based on the right set of numbers.
Reading Company Results
Listed companies usually share their financial performance every three months and then publish a detailed annual report at the end of the financial year.
| Quarter | Period |
| Q1 | April-June |
| Q2 | July-September |
| Q3 | October-December |
| Q4 | January-March |
Suppose you read the headline: “Company XYZ reports 18% revenue growth in Q2 FY27”.
Here’s how to understand it:
- Q2 means the company is reporting its performance for July to September
- FY27 generally refers to the financial year from 1 April 2026 to 31 March 2027 (it’s always worth checking the company’s reporting convention)
- You can compare the 18% growth with Q2 of the previous financial year, to see how the business has performed over the same period
Reading Financial Reports Correctly
Companies prepare most financial documents for a specific financial year. Before looking at the numbers, always check which period the report covers, including:
- Annual reports
- Balance sheets
- Profit and loss statements
- Cash flow statements
- Credit rating reports
- Bond information memoranda
- Mutual fund factsheets
If one company’s report covers FY 2025-26 and another covers FY 2026-27, you can’t compare their profits directly because they relate to different reporting periods.
Tracking Your Investment Income
The financial year also helps you organize your own investment records, including:
- Interest earned from bonds or fixed-income investments
- Dividends received from shares
- Capital gains when you sell an investment
- Mutual fund statements and portfolio performance
- Tax planning before the financial year ends on 31 March
Suppose you invest in a bond in August and receive interest in December. Even if the bond matures a few years later, you record the interest received in December for that financial year. This helps you maintain accurate records and report your investment income correctly when required.
Why Investors Pay Attention to the Union Budget?
The government presents the Union Budget before the start of a new financial year, because many tax rules, investment-related changes, and government policies become effective from 1 April. For you as an investor, this is a good time to review whether any changes affect your investments, taxes, or long-term financial plans before making new investment decisions.
A Quick Checklist Before You Compare Investments
Before reading financial reports or comparing investments, ask yourself:
- Which financial year do these numbers relate to?
- Am I comparing the same quarter or the same financial year?
- Are these quarterly results or annual results?
- Are the financial statements audited?
- Have any tax or investment rules changed for the current financial year?
Conclusion
The financial year provides the common timeline for accounting, taxation, business reporting, and investments in India.
As tax terminology evolves and financial reporting continues to follow the financial year, understanding which reporting period a document refers to becomes increasingly important.
Whether you’re reviewing company results, tracking investments, or reading tax records, identifying the correct reporting period can help you interpret financial information more accurately and compare information with greater confidence.
