Choosing between the old and new income tax regimes depends on correct form submission and awareness of the latest rule changes under the Income Tax Act, 1961. Form 10-IE was used earlier to opt into the new regime when the old regime was the default, while Form 10-IEA now serves as the declaration form for taxpayers opting out of the default new regime to choose the old one. These forms ensure accurate tax computation, correct TDS treatment, and smooth filing, especially for taxpayers with business or professional income. With regime rules updated from FY 2023-24 onward, understanding which form applies has become essential for compliant tax filing.

What Is Form 10-IE Under the Income Tax Act?
Form 10-IE was the declaration form introduced when the new tax regime under Section 115BAC first became available in FY 2020–21. It allowed individual and HUF taxpayers to officially opt for the new regime while filing their income tax return. The form had to be submitted before filing the ITR if a taxpayer had business or professional income. For salaried individuals without business income, selecting the regime directly inside the ITR was sufficient. Form 10-IE helped the Income Tax Department register the taxpayer’s preference and ensured correct tax computation based on their chosen regime.
What Is Form 10-IEA and Why It Replaced Form 10-IE?
Form 10-IEA replaced Form 10-IE after the law was amended to make the new tax regime the default option from FY 2023–24 onward. Since the old regime is no longer automatic, taxpayers must now actively opt out of the default new regime if they wish to continue claiming deductions and exemptions allowed earlier. Form 10-IEA is specifically designed for this purpose. It records whether a taxpayer wants to stay in the default new regime or switch to the old regime while filing their return. This new form aligns the filing process with the updated tax structure and compliance requirements introduced by the government.
Form 10-IE vs 10-IEA: Key Differences Explained
Form 10-IE was used to opt into the new tax regime when the old regime was the default. In contrast, Form 10-IEA is used to opt out of the new tax regime now that the new system is the default. Form 10-IE applied mainly to individuals with business or professional income. Form 10-IEA continues to apply to similar taxpayers but is also used to revert back to the old regime in future years under specific conditions. Form 10-IE was a one-time declaration, whereas 10-IEA governs regime switching going forward under the amended rules of Section 115BAC.
How Regime Selection Works Under the Old and New Tax Regimes
Under the current rules, the new tax regime applies automatically unless the taxpayer chooses otherwise. To shift to the old regime, deductions like 80C, 80D, HRA, home loan interest for self-occupied properties, and several exemptions become available again. Individuals without business income can choose their regime directly inside their ITR every year, while those with business or professional income must follow stricter rules and can switch only once by filing Form 10-IEA. Once moved back to the old regime, switching again requires meeting specific conditions set under Section 115BAC.
Is the Old Tax Regime Allowed Without Filing Form 10-IEA?
For taxpayers who do not have business income—such as salaried individuals or pensioners—the old regime can be selected directly in the ITR without filing Form 10-IEA. However, taxpayers with business or professional income must submit Form 10-IEA to opt out of the default new regime. Without submitting the form, their filing will automatically be computed under the new tax system even if deductions are entered. This makes Form 10-IEA mandatory for eligible categories.
How Form 10-IEA Affects Deductions, Exemptions, and TDS
Selecting the old regime through Form 10-IEA reactivates major deductions and exemptions such as Section 80C investments, medical insurance premiums, HRA, LTA, interest on housing loans for self-occupied property, and other allowances. Employers also compute TDS differently based on the regime selected. When the old regime is chosen through Form 10-IEA, the TDS for the year is aligned with the available deductions and exemptions. If no form is filed (in cases where it is mandatory), TDS and tax calculations will default to the new regime.
When Filing Form 10-IEA Becomes Mandatory for Taxpayers
Form 10-IEA becomes necessary when a taxpayer with business or professional income wants to choose the old tax regime. It is also required if such taxpayers want to revert back to the old system in future years. For individuals without business income, the form is not needed and regime selection can be done directly while filing the return. The declaration is time-sensitive and must be submitted before filing the ITR for the relevant assessment year.
Choosing the Right Tax Regime: Practical Considerations
Selecting the right tax regime depends on the taxpayer’s income, deductions, and future financial plans. The old regime is usually better for those claiming significant deductions such as home loan interest, 80C investments, medical insurance premiums, or education loan interest. The new regime benefits individuals with fewer deductions and simpler income structures. Form 10-IEA ensures that taxpayers with business income can retain or switch regimes formally after evaluating their financial benefits.
Form 10-IEA Filing Timeline and Compliance Rules
The form should be filed before submitting the ITR for the relevant assessment year. Once filed, taxpayers with business income can revert back to the new regime only once in their lifetime. After switching back, they cannot opt for the old regime again unless they stop business operations entirely. Compliance is crucial because missing the filing deadline locks the taxpayer into the default new regime for that year.
Common Errors While Selecting Tax Regime in ITR
Many taxpayers make mistakes while selecting the correct tax regime in their Income Tax Return simply because they are unaware of the rules and procedural requirements. A common error is choosing a regime without filing Form 10-IEA when required. For individuals opting for the new tax regime, Form 10-IEA must be submitted before filing the return, and failing to do so results in the old regime being applied by default. This leads to incorrect tax calculations, higher tax liability, or rejection of the intended choice.
Another frequent mistake occurs when taxpayers calculate their taxes assuming the old regime rules apply even though the new regime has become the default. They enter multiple deductions—such as Section 80C, 80D, HRA, and home loan benefits—without realizing that these deductions are not permitted under the new regime. This mismatch often causes discrepancies between AIS, Form 16, and the ITR, resulting in delays, notices, or reprocessing.
Some taxpayers also fail to compare both regimes before selecting one. Without properly evaluating available deductions, exemptions, and the net tax payable under each regime, they may choose a less beneficial option and end up paying more tax than necessary. In many cases, incorrect selection happens because taxpayers rush through the filing process without reviewing employer declarations or cross-checking Form 16.
Using professional or automated tax-filing platforms significantly reduces these risks. Such platforms guide users through eligibility checks, help calculate taxes under both regimes, validate whether Form 10-IEA is needed, and ensure the regime selection aligns with the taxpayer’s income structure. By following a structured filing process, taxpayers can avoid common mistakes and choose the most beneficial regime confidently and accurately.

FAQs
Q1. Who needs to file Form 10-IEA? Form 10-IEA is required for individuals or Hindu Undivided Families (HUFs) who have income from business or profession and want to opt out of the default new tax regime under Section 115BAC(1A). Since the new regime is now the default, these taxpayers must file Form 10-IEA if they prefer to use the old tax regime for claiming deductions such as 80C, 80D, HRA, or home loan benefits. Salaried individuals without any business or professional income are not required to file this form and can switch between regimes directly while filing their ITR.
Q2. Can Form 10-IEA be revised after submission? Once Form 10-IEA is submitted for a particular assessment year, it generally cannot be revised. The tax regime selection becomes locked for that assessment year as per Section 115BAC rules. Any changes can be made only while filing the ITR, provided the form is not mandatory in that case. For business taxpayers, revisions are not permitted after submission, so it is important to evaluate both regimes carefully before filing.
Q3. Is Form 10-IEA mandatory for salaried taxpayers? Salaried individuals who do not have business or professional income do not need to file Form 10-IEA. They can freely choose between the old and new regimes while submitting their income tax return. Their selection in the ITR itself is treated as valid without the need for a separate form. However, if any salaried person has business income (for example, side freelancing or consultancy), the form becomes mandatory.
Q4. When should Form 10-IEA be filed? Form 10-IEA must be filed before submitting the ITR for the relevant assessment year. The Income Tax Department does not allow filing the form after the return has been filed. Therefore, taxpayers who require the old regime must complete Form 10-IEA in advance. Submitting the ITR without the form will automatically place the taxpayer in the new tax regime.
Q5. What happens if Form 10-IEA is not filed when required? If Form 10-IEA is mandatory but not submitted, the taxpayer will default to the new tax regime. As a result, all deductions and exemptions available under the old regime—such as 80C, 80D, HRA, and home loan interest benefits—will be disallowed. The Income Tax Department may raise queries or adjustments in the return due to the mismatch between claimed deductions and the selected regime.
Q6. Can taxpayers switch back to the new regime after filing Form 10-IEA? Taxpayers with business or professional income can switch back to the new regime only once in their lifetime. After switching back, they cannot revert to the old regime again unless their business income stops completely. This one-time-switch restriction ensures stability in tax planning for business taxpayers. Salaried taxpayers without business income can switch regimes freely each year without such restrictions.
Q7. Does Form 10-IEA affect TDS deducted by employers? Yes, Form 10-IEA can influence TDS calculations. Employers compute TDS based on the tax regime declared by the employee. If an individual submits Form 10-IEA for the old regime, the employer adjusts TDS accordingly and allows old-regime deductions while estimating annual taxable income. This helps reduce excess TDS deductions during the year.
Q8. Can deductions under 80C, 80D, and HRA be claimed without filing Form 10-IEA? Only salaried individuals who do not have business or professional income can claim old-regime deductions directly by selecting the old regime in their ITR. However, individuals or HUFs with business income must file Form 10-IEA before claiming any old-regime deductions. Without this form, the new regime becomes the default and no such deductions are allowed in the ITR.
Q9. What documents are required for Form 10-IEA? Form 10-IEA requires basic taxpayer information such as PAN, address, and residential status. It also requires confirmation regarding business or professional income, along with a declaration of the preferred tax regime for the assessment year. No additional income proof needs to be uploaded, but taxpayers must keep supporting documentation—like books of accounts and income details—ready in case the department requests verification.
Q10. Can Form 10-IEA be filed offline? No. Form 10-IEA can only be filed online through the Income Tax Department’s e-filing portal. Taxpayers must log in, navigate to the “Forms Filed” section, and submit Form 10-IEA electronically. Offline or physical submission is not permitted.
Q11. How does TaxBuddy help with Form 10-IEA? TaxBuddy evaluates whether Form 10-IEA is required based on the taxpayer’s income profile. It compares both regimes, calculates potential tax savings, and ensures the correct form is filed. The platform automatically prepares and submits Form 10-IEA where required, preventing mistakes or missed submissions. This ensures taxpayers select the most beneficial regime without errors or compliance issues.
Q12. Does Form 10-IEA apply to senior citizens? Senior citizens who have income only from pension, interest, or rental income do not need Form 10-IEA. However, senior citizens with business or professional income must file Form 10-IEA if they want the old tax regime. Retirees with no business income can freely select their preferred regime directly while filing their ITR without submitting the form.
