Calculation Formula & Methodology
Computes Indian income tax liability by comparing the New Tax Regime (Section 115BAC) and the Old Tax Regime for FY 2024-25 and FY 2025-26. Incorporates the standard deduction of ₹75,000 (New Regime) or ₹50,000 (Old Regime), Section 87A full tax rebate up to ₹7,00,000 (New Regime), and 4% Health & Education Cess.
Example: Salaried individual with ₹10,00,000 annual gross income (New Regime FY 2025-26)
Inputs: Gross Income = ₹10,00,000 | Standard Deduction = ₹75,000 | Net Taxable Income = ₹9,25,000
Calculation: Slab 0-3L: Nil | 3L-7L (4L @ 5%): ₹20,000 | 7L-9.25L (2.25L @ 10%): ₹22,500 | Total Tax = ₹42,500 + 4% Cess (₹1,700)
Outcome: Total Tax Payable under New Regime = ₹44,200
Key Insights & Financial Takeaways
- Standard Deduction Update: In the Union Budget, standard deduction for salaried taxpayers under the New Tax Regime was increased to ₹75,000 (compared to ₹50,000 in Old Regime).
- Rebate under Section 87A: Under the New Tax Regime, individuals with taxable income up to ₹7 Lakh pay zero tax after the full 87A rebate.
- Old vs New Decision: The Old Regime benefits those with heavy deductions (Section 80C up to ₹1.5L, 80D health insurance, HRA, home loan interest under Section 24b). For individuals with minimal investments, the New Regime offers lower baseline slab rates.
