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.

What is Section 115BAC – The New Tax Regime Slabs?

  • The income tax slabs are relaxed under the new regime, with reduced deductions and exemptions. 
  • Section 115BAC was amended in Budget 2023, making the new tax regime the default from FY 2023–24 onwards. 
  • If an individual or HUF wants to opt for the old tax regime, he can do so at the time of filing the returns. 
  • If such individual or HUF has business income, then he must file Form 10-IEA before the due date of filing ITR.
  • Old regime cannot be chosen after due date, the taxpayer can file ITR only under the new regime.

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)

Income Amount (Rs)Old regime (Rs)New regime (Rs)
Salary12,50,00012,50,00012,50,000
Less: Standard deduction50,00050,00075,000
Less: Professional tax2,4002,400-
Gross total income11,97,60011,97,60011,75,000
Less: Deduction u/s 80C1,50,0001,50,000-
Total income10,47,60010,47,60011,75,000
Income tax (Including 4% cess) 1,31,85179,300

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)

Income Old regime (Rs)New regime (Rs)
Salary10,00,00010,00,000
Less: HRA Exemption70,000-
Less: Standard deduction50,00075,000
Less: Professional tax2,400-
Gross total income8,77,6009,25,000
Less: Deduction u/s 80C1,50,000-
Less: Deduction u/s 80D50,000-
Total income6,77,6009,25,000
Income tax48,02042,500
Add: Education cess @ 4%1,9211,700
Total tax49,94144,200

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:

Annual income*Tax under the old regime (Rs) (A)Tax under the new regime (Rs) (B)Tax savings under the new regime (Rs) (A - B)
Rs 7,50,00054,600054,600
Rs 10,00,0001,06,60044,20062,400
Rs 12,50,0001,79,40079,3001,00,100
Rs 15,00,0002,57,4001,30,0001,27,400

*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.

Treatment of House Property Deductions and Business Losses Under the New Tax Regime

Deduction / Loss claimedOld RegimeNew Regime
Self-Occupied House PropertyInterest on housing loan up to ₹2 lakh deductible; loss can be set off.No deduction for interest; no set-off of loss.

Example: Sec. 35 Deduction LossCan be carried forward and set off in future yearsCannot be set off if deduction not allowed under new regime

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.
