Executive Summary & Key Takeaways
- •The New Tax Regime provides a ₹75,000 Standard Deduction and zero tax on income up to ₹7.75 Lakhs with Section 87A rebate.
- •The Old Tax Regime is superior only if total deductions (80C, 80D, HRA, Home Loan Interest, NPS) exceed ₹3.75 Lakhs to ₹4.25 Lakhs.
- •Salaried employees can switch regimes every financial year when filing their annual ITR.
The Shifting Landscape of Indian Income Tax
The Government of India has established the New Tax Regime (Section 115BAC) as the default tax regime, offering simplified, lower slab tax rates in exchange for forgoing most itemized exemptions and deductions.
New Tax Regime Slabs & Standard Deduction
- Standard Deduction: Flat ₹75,000 for salaried employees and pensioners.
- 0 to ₹3,00,000: Nil (0%)
- ₹3,00,001 to ₹7,00,000: 5% (100% rebated via Section 87A up to ₹7L taxable income)
- ₹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%
The Breakeven Rule of Thumb
For an individual earning ₹15 Lakhs gross CTC:
- If your total deductions (80C + 80D + HRA + 80CCD + Home Loan interest) are less than ₹3,75,000, the New Tax Regime saves you more tax and eliminates paperwork.
- If you pay substantial metro house rent (HRA > ₹2.5L) and max out 80C + 80D + NPS (total deductions > ₹4.25L), the Old Tax Regime remains optimal.
