Switching Tax Regimes? Here’s Why Form 10-IEA is Crucial for You

Numerous taxpayers have a question in their minds: What is Form 10-IEA, and who is required to file it? Form 10-IEA is a very crucial form for you if you run a business, trade, or work as a freelancer and want to opt for the Old Tax Regime. It is the only way through which the tax department allows taxpayers to choose between the old and new tax regimes. If taxpayers do not submit this form on time, they are automatically shifted to the New Tax Regime, which might not be beneficial for everyone.

What is Form 10-IEA?

Form 10-IEA is an official Income Tax form introduced by the Income Tax Department of India. It is used by individuals who have income from a business or profession, such as freelancers, traders, or consultants, when they want to opt for the Old Tax Regime instead of the default New Tax Regime.

Beginning from the Financial Year (FY) 2023-24, the tax department made the New Tax Regime the default, meaning if you do not opt for the Old Tax Regime, you will automatically be shifted to the New Tax Regime and your tax will be calculated under the New Tax Regime. Therefore, if you want to stay or switch to the Old Tax Regime, you should first inform the Income Tax Department. This is reported to the department by filing Form 10-IEA.

Who is Required to File Form 10-IEA?

Form 10-IEA is compulsory to be filed by individuals who have income from business or profession, such as Freelancers, Futures & Options (F&O) traders, Intraday traders, Independent consultants and Small business owners.

These individuals are not permitted to choose a tax regime every year like salaried employees. These individuals are required to file this form to switch or to continue in the Old Tax Regime.

When Do You Need to File Form 10-IEA?

Below are listed the different situations or conditions when Form 10-IEA needs to be filed:

1. If you were under the New Tax Regime in financial year 2023-24 and want to switch to the Old Tax Regime for financial year 2024-25, then yes, you must file Form 10-IEA to make the switch.

2. If you were already under the Old Tax Regime in financial year 2023-24 and want to continue with it in financial year 2024-25, then no, you do not need to file Form 10-IEA again, as you’re not changing anything.

3. If you were under the Old Tax Regime in the financial year 2023-24 and want to switch to the New Tax Regime for the financial year 2024-25, then yes, you must file Form 10-IEA again to inform the department about this change.

4. If you were under the New Tax Regime in financial year 2023-24 and want to stay with it for financial year 2024-25, then no, you are not required to file Form 10-IEA, because the New Regime is already the default, and you’re not making any changes.

5. If you are filing taxes for the first time in the financial year 2024-25 and want to choose the Old Regime, then yes, you must submit Form 10-IEA to inform your preference.

6. If you are filing taxes for the first time in the financial year 2024-25 and want to follow the New Regime, then no, you are not required to file Form 10-IEA, because the New Regime is the default for new taxpayers.

How Many Times Can You File Form 10-IEA?

One is allowed to file Form 10-IEA only twice in his/her entire lifetime if he/she has business or professional income:

  • Once to opt out of the New Tax Regime (and enter the Old Regime)
  • Once again, to opt back into the New Tax Regime (if you had earlier left it)

Note: Form 10-IEA is only required to be submitted by taxpayers with business/professional income. Salaried individuals who do not have such income are not required to submit this form; they can switch regimes every year while filing their tax return, without using Form 10-IEA.
