New Tax Regime Slabs, Deductions and Exemptions Under Section 115BAC

Section 115BAC of the Income Tax Act deals with the new tax regime, offering concessional slab rates in exchange for fewer deductions and exemptions. It is now the default tax regime for individuals and Hindu Undivided Families (HUFs). While the new regime simplifies tax compliance and benefits those who do not claim many deductions, taxpayers still have the option to choose the old regime. Understanding Section 115BAC is essential for making informed tax planning decisions.

Can I switch Between Tax Regimes?

The new regime is default tax regime. The assess can still choose to file under old regime.

For Salaried Taxpayer

• Choice needs to be made in the beginning of the financial year.
• The choice made by the employee at the beginning of the FY is only for the purpose of deducting TDS and it is changeable while filing the return i.e., July 2025. 
• If no choice is made by the employee at the beginning of the financial year, TDS deducted by the employer under new regime as it is default regime.
• Salaried employee can choose to file under new regime in one year and old regime in the next year, or vice versa.

Non Salaried Taxpayer

• Taxpayers with an income from business or profession (non-salaried) cannot opt-in and opt-out of the new tax regime every year.
• Once a non-salaried opts out of the new tax regime, they cannot opt-in again for the new tax regime in the future.
• They need not declare or intimate their choice to anyone during the year.

The due date for tax filing for the FY 2024-25 (AY 2025-26) is extended to 15th September 2025. If you have not filed your return within 15th September, you have until 31st December, 2025 to submit your Belated Return. 

How Do I Choose the New Tax Regime and Plan My Taxes?

• From a tax planning perspective, choosing the tax regime at the beginning of the financial year is essential. 
• A taxpayer must compare the income tax under the new tax regime with the old regime. 
• Once the taxpayer chooses the tax regime at the beginning of the year, the investments and TDS or advance tax payable calculations are made accordingly. 
• Also, the taxpayer has to furnish Form 10IEA to the income tax department before filing the return if the taxpayer intends to opt for the old tax regime.

Illustrations showing the Best Tax Regime under Different situations

Below are a few illustrations explaining the situations wherein the new and old regimes are better in terms of tax outflow.  

Example 1: New Regime Advantage in Tax Outflow (FY 2024-25)

In the above example, for an income of Rs 12.5 lakhs, the new tax regime is significantly beneficial by Rs 52,551. However, if you claim further deductions for interest on housing loan for SOP, health insurance, investment in NPS, education loans and so on, the old regime will be helpful in respect of tax savings.

Example 2: Where the old regime is better in respect of tax outflow (FY 2024-25)

In Example 2, for an income of Rs 10 lakh having HRA exemption and 80D deduction, the old tax regime is beneficial by Rs 5,741.

If an individual claims lower deductions for tax savings towards health insurance, investment in NPS and so on, the new regime will be more beneficial against individuals who utilize the tax-saving investments.

Also, individuals with an income bracket between Rs 5-15 lakh with lower deductions claims will benefit from the new regime. In contrast, individuals can benefit more from the old regime by making tax-saving investments.

The tax payable under both the new and the old regimes without claiming deductions and exemptions for FY 2024-25 (AY 2025-26) is as below:

*Assumed that the annual income is after reducing the standard deduction under both old and new regimes.  
The above table shows that the new tax regime generally saves taxes for taxpayers who don’t claim any deductions or exemptions.

Conclusion

Based on the provided information, it is evident that the current tax regime offers advantages for the specified income level. If an individual chooses to claim fewer deductions for tax savings, such as investments in NPS or health insurance, the new regime becomes more advantageous compared to individuals who rely on tax-saving investments.

It is important to consider that individuals with an income ranging from Rs.5 lakh to Rs.10 lakh, who opt for lower deductions, will benefit from the new regime. Conversely, individuals falling into higher income tax brackets, earning more than Rs.15 lakh annually, can benefit from the old regime by utilizing tax-saving investments.
