New Tax Regime vs Old Tax Regime: Which One Saves You More?
Since FY 2023-24, India runs two parallel income tax regimes. The new regime is the default with lower slab rates but almost no deductions. The old regime keeps higher slabs but lets you claim 80C, 80D, HRA, and home loan interest. The right choice depends on your deductions, not your income.
Side-by-side comparison table
| Factor | New Regime | Old Regime |
|---|---|---|
| Default regime (FY 2024-25) | Default (auto-applied) | Must explicitly opt in |
| Lowest taxable income bracket | ₹0-3L: 0% | ₹0-2.5L: 0% |
| Mid bracket | ₹7-10L: 10% | ₹5-10L: 20% |
| Highest standard bracket | ₹12L+: 30% | ₹10L+: 30% |
| Section 87A rebate | Zero tax up to ₹7L | Zero tax up to ₹5L |
| Standard deduction (salary) | ₹75,000 | ₹50,000 |
| 80C (PPF, ELSS, EPF, etc.) | Not allowed | ₹1.5 lakh deduction |
| 80CCD(1B) NPS extra | Not allowed | ₹50,000 deduction |
| 80D health insurance | Not allowed | ₹25K-1L deduction |
| HRA exemption | Not allowed | Fully allowed |
| Home loan interest (self-occupied) | Not allowed | ₹2L deduction |
| Employer NPS 80CCD(2) | Allowed | Allowed |
When the new regime wins
Below ₹15 lakh income with limited deductions: new regime almost always wins. The ₹7 lakh 87A rebate cliff makes income up to ₹7L taxable-zero in the new regime — far more generous than the old regime's ₹5L cap. At ₹10L income with no deductions, new regime saves ~₹25K vs old.
Freelancers, consultants, and self-employed without major deductions: new regime is simpler and lower tax. The complexity of tracking 80C investments + 80D premium + HRA receipts is replaced by a clean slab calculation.
When the old regime wins
Above ₹15-20 lakh income with full 80C + 80CCD(1B) + 80D + HRA + home loan interest claimed: old regime usually wins by ₹30K-1L per year. At ₹25L income with ₹6L of total deductions claimed, old regime saves ~₹50K vs new.
Salaried with home loan and rented previous accommodation: HRA + home loan interest can combine for ₹4-5L of deductions in transition years, making old regime decisively better. Senior citizens with significant 80D health insurance + LIC premium also benefit from old regime.
The cutoff: how much deduction does old regime need to win?
Rough rule of thumb: old regime needs roughly ₹3.75 lakh of deductions on top of the standard deduction to break even with new regime. ₹1.5L (80C) + ₹50K (NPS) + ₹50K (80D family senior) + ₹1.25L (HRA average) ≈ ₹3.75L. If you can't comfortably hit that, new regime is the simpler choice.
Salary structure matters too. If your basic is ₹50K/month and HRA is ₹25K/month, claiming HRA exemption alone gives ~₹3L deduction in metros. Combined with 80C/80D, old regime wins handily.
Run both calculations every year
The Indian income tax calculator on this site computes both regimes and shows the rupee difference. Run it once a year in March before submitting your tax declaration to your employer (so payroll applies the optimal regime for TDS) and again at filing.
Salaried individuals can switch regimes every year — there's no lock-in. Business/professional income lets you switch once in a lifetime to new regime, then it becomes permanent. Make the choice deliberate, not by default.
