The Dual Tax System in India: Old vs. New Regime
Taxpayers in India have the option to choose between two tax regimes: the **Old Tax Regime** and the **New Tax Regime** (introduced under Section 115BAC). Under the New Tax Regime, tax slabs are significantly lower, but taxpayers must give up almost all deductions and exemptions. Under the Old Tax Regime, tax slabs are higher, but you can claim multiple deductions (Section 80C, 80D, HRA, and Home Loan interest) to reduce your taxable income.
Starting from FY 2023-24, the **New Tax Regime is the default option**. If you wish to file under the Old Regime, you must actively select it when filing your Income Tax Return (ITR).
Latest Income Tax Slab Structures (FY 2025-26 & FY 2026-27)
The slabs for the New Tax Regime have been updated in the recent Union Budgets to offer more relief to middle-income taxpayers:
New Tax Regime Slabs:
- Up to ₹3,00,000: Nil
- ₹3,00,001 to ₹7,00,000: 5%
- ₹7,00,001 to ₹10,00,000: 10%
- ₹10,00,001 to ₹12,00,000: 15%
- ₹12,00,001 to ₹15,00,000: 20%
- Above ₹15,00,000: 30%
Additionally, salaried employees receive a **Standard Deduction of ₹75,000** under the New Tax Regime. The rebate under Section 87A ensures that individuals with a net taxable income **up to ₹7,00,000 pay zero tax** (which translates to a gross salary of ₹7,75,000 when including the standard deduction).
Old Tax Regime Slabs:
- Up to ₹2,50,000: Nil
- ₹2,50,001 to ₹5,00,000: 5%
- ₹5,00,001 to ₹10,00,000: 20%
- Above ₹10,00,000: 30%
Salaried employees receive a **Standard Deduction of ₹50,000** under the Old Regime. The rebate under Section 87A ensures zero tax for net taxable incomes **up to ₹5,00,000**.
Key Deductions under the Old Tax Regime
If you choose to file under the Old Regime, you can reduce your taxable income using these common deductions:
- Section 80C: Deductions up to **₹1,50,000** for investments in EPF, PPF, ELSS mutual funds, Life Insurance premiums, National Savings Certificates (NSC), and children's tuition fees.
- Section 80D: Deductions for health insurance premiums up to **₹25,000** for self/family, and an additional **₹50,000** for senior citizen parents.
- Section 24(b): Deductions up to **₹2,00,000** on interest paid for a home loan on self-occupied property.
- HRA (House Rent Allowance): Rent paid is partially tax-exempt under Section 10(13A) for salaried individuals.
Regime Comparison Example
Let's compare the tax liability for a salaried employee with a gross salary of **₹12,00,000 (12 Lakhs)** who has total deductions of **₹1,50,000** (under Section 80C):
New Tax Regime Calculation:
- Gross Income = ₹12,00,000
- Less: Standard Deduction = ₹75,000
- Net Taxable Income = ₹11,25,000
- Slab Tax:
- ₹0 to ₹3,00,000: Nil
- ₹3,00,001 to ₹7,00,000 (5%): ₹20,000
- ₹7,00,001 to ₹10,00,000 (10%): ₹30,000
- ₹10,00,001 to ₹11,25,000 (15%): ₹18,750
- Subtotal Tax = ₹68,750
- Rebate 87A = ₹0 (income exceeds ₹7 Lakhs)
- Add: Cess (4% of ₹68,750) = ₹2,750
- Total New Tax Payable = ₹71,500
Old Tax Regime Calculation:
- Gross Income = ₹12,00,000
- Less: Standard Deduction = ₹50,000
- Less: Section 80C Deductions = ₹1,50,000
- Net Taxable Income = ₹10,00,000
- Slab Tax:
- ₹0 to ₹2,50,000: Nil
- ₹2,50,001 to ₹5,00,000 (5%): ₹12,500
- ₹5,00,001 to ₹10,00,000 (20%): ₹1,00,000
- Subtotal Tax = ₹1,12,500
- Rebate 87A = ₹0
- Add: Cess (4% of ₹1,12,500) = ₹4,500
- Total Old Tax Payable = ₹1,17,000
In this scenario, the **New Tax Regime saves you ₹45,500** compared to the Old Regime. You would need total deductions of at least **₹3,00,000** under the Old Regime to match the tax liability of the New Regime.
