A big change in Income Tax Bill 2025! The new Tax Year replaces the Previous Year & Assessment Year. Know how it affects your tax filing with simple examples.
When it comes to filing income tax in India, terms like Previous Year, Assessment Year, and now the proposed Tax Year can be confusing. The government has introduced changes in the Income Tax Bill 2025 to simplify tax-related terminology. In this blog post, I will explain these terms in simple, everyday language with practical examples.
Income Tax Bill 2025 – Tax Year Vs Assessment Year Vs Previous Year

1. What is a Previous Year?
The Previous Year (also known as the Financial Year) is the 12-month period in which you earn income. In India, it starts on April 1st and ends on March 31st of the following year.
Example of Previous Year:
- If you earn income between April 1, 2023 – March 31, 2024, that period is called Previous Year 2023-24.
- Your salary, business profits, rent from property, or any other taxable income earned in this period falls under the Previous Year 2023-24.
Think of it this way: The previous year is like a piggy bank where you collect all your income before you count and pay taxes on it.
2. What is an Assessment Year?
The Assessment Year is the 12-month period immediately following the Previous Year, during which you evaluate and file taxes on the income earned in the previous year.
Example of Assessment Year:
- For the income earned in the Previous Year 2023-24 (April 1, 2023 – March 31, 2024), the Assessment Year is 2024-25 (April 1, 2024 – March 31, 2025).
- You file your Income Tax Return (ITR) and pay taxes during the Assessment Year 2024-25 for the income earned in the Previous Year 2023-24.
Think of it this way: The assessment year is like an accountant checking the money in your piggy bank and making sure you pay the right tax on it.
3. What is the New “Tax Year” Concept?
The Income Tax Bill 2025 proposes to replace the terms “Previous Year” and “Assessment Year” with “Tax Year” to make the taxation process easier for everyone.
How Will Tax Year Work?
- Under the new system, the Tax Year will be the same 12-month period (April 1st – March 31st) when both income is earned and taxes are filed.
- This means that instead of separating the Previous Year and Assessment Year, there will be just one term – Tax Year.
Example of Tax Year:
- If you earn income between April 1, 2024 – March 31, 2025, that entire period will be called Tax Year 2024-25.
- You will file taxes for Tax Year 2024-25 within the same period, instead of waiting for an Assessment Year.
Think of it this way: With the Tax Year concept, the piggy bank (Previous Year) and the accountant’s check (Assessment Year) happen together, making tax filing simpler and faster.
Key Differences Tax Year Vs Assessment Year Vs Previous Year
Feature | Previous Year (Old) | Assessment Year (Old) | Tax Year (New) |
---|---|---|---|
Definition | The year in which income is earned | The year in which income is assessed and taxes are filed | A single term covering both earning and tax filing |
Time Frame | April 1st – March 31st | April 1st – March 31st (following year) | April 1st – March 31st (same year) |
Filing Taxes | Not applicable | Filed after the previous year ends | Filed within the same tax year |
Example | Income earned in 2023-24 | Taxes filed in 2024-25 | Income earned and taxed in 2024-25 |
Complexity | Requires understanding of two separate terms | Requires waiting for assessment after income is earned | A single term for easier understanding |
Why is This Change Important?
1. Eliminates Confusion
- No need to remember different years for income and tax filing.
- A single Tax Year makes it easier for taxpayers to understand.
2. Simplifies Taxation
- Instead of waiting for an assessment year, taxpayers can file their taxes within the same tax year.
3. Encourages Faster Compliance
- More clarity means individuals and businesses can be more proactive in filing taxes.
The new Tax Year system, if implemented, will replace the confusing structure of the Previous Year and Assessment Year, making tax filing simpler and more transparent for Indian taxpayers. This change is aimed at reducing confusion and ensuring that individuals and businesses can easily understand and comply with tax laws.
With this simpler approach, the government hopes to improve tax compliance and streamline the process, making it as easy as possible for everyone.
