Section 115BAC – Understanding the New Income Tax Regime

Updated: 30-05-2025 13:39:47 PM

IT Department Clarification: The Ministry of Finance issued a clarification on April 13th, 2020 regarding TDS deduction by employers with res pect to the provisions of Section 115BAC. It states that salaried individuals should inform the employer, if they are planning to opt for the new income tax regime u/s 115 BAC, so that the employer can deduct the TDS as per the new slab rates. If an employer fails to inform about his/ her decision to opt for new tax regime, then the employer will continue to deduct TDS as per the old (existing) slab rates.

During the Budget 2020 speech, the Finance Minister Nirmala Sitharaman announced the insertion of a new section called 115BAC into the Income Tax Act in the Union Budget 2020. Section 115 BAC, effective from FY 2020-21, deals with the new and optional income tax regime for individuals and Hindu Undivided Families (HUFs). Let us understand the new slab rates, eligibility criteria for the new regime and the deductions that are allowed or disallowed under Section 115BAC. Moreover, we will compare the two regimes to help you select the more suitable one among the two. 

What is Section 115BAC

Section 115BAC is the newly inserted section in the Income Tax Act, 1961 that deals with the new income tax regime. This section and alternate tax regime was introduced in Union Budget 2020 and is applicable to individuals and Hindu Undivided Families (HUFs) only. A key feature of this new regime is that the income tax slab rates have been significantly reduced. However, the new rates come at the cost of various key income tax exemptions and deductions, which are currently available under the old (existing) income tax regime. 

The following table shows the new slab rates as per Section 115BAC for FY 2025-2026

Annual Income	New Income Tax Slab Rate
Nil to Rs. 4 lakh	Exempt
Rs. 4 lakh to Rs. 8 lakh	5%
Rs. 8 lakh to Rs. 12 lakh	10%
Rs. 12 lakh to Rs. 16 lakh	15%
Rs. 16 lakh to Rs. 20 lakh	20%
Rs. 20 lakh to Rs. 24 lakh	25%
Above Rs. 24 lakh	30%

What are the eligibility criteria for the new tax regime

Starting AY 2021-22, individuals and HUFs will have the option to pay income tax as per the new (reduced) income tax slab rates provided their total income for the relevant FY satisfies the following conditions.

• The declared income does not include any business income.
• It is calculated without any exemptions or deductions provided under the following  

• Chapter VI-A except those u/s 80CCD/ 80JJAA,
• Section 24b,
• Clause (5)/(13A)/(14)/(17)/(32) of Section 10/10AA/16,
• Section 32(1)/ 32AD/ 33AB/ 33ABA,
• Section 35/ 35AD/ 35CCC,
• Clause (iia) of Section 57.

• It is calculated without setting off losses from any earlier assessment year (AY) due to the above-mentioned deductions or from house property.
• It is calculated without claiming any depreciation under clause (iia) of Section 32.
• It is calculated without any exemption or deduction with respect to any allowances or perquisites. 

Deductions and exemptions not allowed under Section 115BAC

The following table shows the major income tax deductions and exemptions that have been disallowed under the new income tax regime. Please note that the new regime is optional in FY 2023-24 and you may opt for the old (existing) regime, where all of the following deductions can be claimed.

Major Deductions under Chapter VIA (u/s 80C, 80CCC, 80CCD, 80DD, 80DDB, 80E, 80EE, 80EEA, 80G, 80IA, etc)	House Rent Allowance (HRA) u/s 10(13A)	Home Loan Interest u/s 24(b)

Important points to consider about the new tax regime

• Section 115BAC of the Income Tax Act deals with the new income tax slab rates, which are applicable only for individuals and Hindu Undivided Families (HUFs).
• Although the new regime comes with significantly reduced slab rates, it takes away a major chunk of tax deductions and exemptions that could be availed under the old regime. 
• The new income tax regime is optional, and you can still opt for the old (existing) regime.
• You cannot opt for the new regime, if you have any business income in the applicable FY.
• The rates of surcharge and cess in the new income tax regime are same as those in the old (existing) regime.
• The option to pay income tax as per the new regime can become invalid for the relevant financial year, if the individual or HUF fails to satisfy any of the conditions mentioned in Section 115BAC. 

Old tax regime vs. new tax regime 

The old (existing) tax regime allows for a variety of income tax deductions and exemptions, and hence is suitable for most of the taxpayers. However, the new tax regime may prove beneficial to those who have not significantly invested in various tax-saving schemes, such as Employee Provident Fund (EPF), Equity Linked Savings Scheme (ELSS), Life Insurance, National Pension Scheme (NPS), National Savings Certificate (NSC), tax-saving Fixed Deposit (FD), etc. Moreover, standard deduction of Rs. 50,000 for salaried individuals and HRA allowance also do not apply under the new tax regime. 

Let us understand how the total tax payout is affected under the two regimes through the following table:

Income Value (Rs.)	Old Tax Regime				New Tax Regime (2023)
	Standard Deduction	Extra Deductions*	Net Taxable Income	Tax @ Old Slabs #	Standard Deduction	Net Taxable Income	Tax @ New Slabs #
Rs. 2,40,000	Rs. 50,000	Rs. 0	Rs. 1,90,000	Rs. 0	Rs. 75,000	Rs. 1,65,000	Rs. 0
Rs. 5,80,000	Rs. 50,000	Rs. 50,000	Rs. 4,80,000	Rs. 0	Rs. 75,000	Rs. 5,05,000	Rs. 0
Rs. 10,50,000	Rs. 50,000	Rs. 2,50,000	Rs. 7,50,000	Rs. 37,500	Rs. 75,000	Rs. 9,75,000	Rs. 0
Rs. 15,50,000	Rs. 50,000	Rs. 3,50,000	Rs. 11,50,000	Rs. 1,57,500	Rs. 75,000	Rs. 14,75,000	Rs. 1,01,250

Note:

# Tax Calculations are without Surcharge and Cess

*Extra Deductions include:

• HRA Exemption
• Loss from House Property
• Deductions Under Sec 80C
• Deductions Under Sec 80D
• Other Deductions

Thus, the new regime u/s 115 BAC may prove beneficial for the high-income group with minimal investment in tax-saving investments. However, the old (existing) regime may be better suited to the low-to-middle-income group if they make sufficient investments in various tax-saving schemes. Hence, there is no set formula to decide between the two regimes. One must calculate the total tax outgo as per both the old and new slab rates before deciding whether to adopt Section 115BAC slab rates or not.
