Old vs New Tax Regime in India — Which Should You Choose?
The new regime is now the default and tax-free up to ₹12 lakh — but the old regime still wins for some. Here's how to decide.

What changed, and why it matters
India now runs two parallel income-tax systems. The new regime offers lower slab rates but removes most deductions and exemptions. The old regime keeps higher rates but lets you subtract popular deductions like 80C investments, HRA and home-loan interest. Since the 2025 budget the new regime is the default and far more generous than before.
Under the new regime in 2026, salaried taxpayers get a ₹75,000 standard deduction and a §87A rebate that makes income up to ₹12 lakh taxable (about ₹12.75 lakh gross) effectively tax-free. That single change pulled most middle-income earners toward the new regime.
| Taxable income | Rate |
|---|---|
| Up to ₹4 lakh | 0% |
| ₹4–8 lakh | 5% |
| ₹8–12 lakh | 10% |
| ₹12–16 lakh | 15% |
| ₹16–20 lakh | 20% |
| ₹20–24 lakh | 25% |
| Above ₹24 lakh | 30% |
When the old regime still wins
The old regime can still come out ahead if you claim large deductions. If you max out 80C (₹1.5 lakh), pay significant rent with an HRA exemption, have home-loan interest under section 24, and contribute to NPS and health insurance, your taxable income can drop enough that the old regime's higher rates apply to a much smaller base.
As a rough rule, the more you genuinely deduct, the more attractive the old regime becomes — but only if those deductions reflect real spending and investment you'd do anyway. Chasing deductions purely to save tax often leaves you worse off in cash terms.
How to actually decide
Don't guess — compute both. Add up the deductions you realistically claim, then calculate tax under each regime on the same gross salary. The regime with the lower total tax wins for that year, and in India you can switch each year if you're salaried (business income has tighter rules).
Our Old vs New Regime calculator does exactly this side by side: enter your salary and the deductions you'd claim, and it shows the tax under both regimes plus a clear recommendation, so you can pick the one that leaves more in your hand.
Where the crossover actually falls
The useful question is not which regime is better but how much deduction you need before the old regime overtakes the new one at your income. The new regime's advantage comes from wider slabs, a higher rebate threshold and a standard deduction available without proof. The old regime's advantage comes entirely from what you can subtract before the slabs apply, so the two curves cross at whatever deduction total closes the rate gap.
That crossover moves with income, which is why a colleague's answer is worthless to you. At lower incomes the new regime's rebate makes it very hard to beat. In the middle of the range a genuine metro rent claim through HRA plus a fully-used 80C often tips it. At higher incomes the deduction limits are fixed while the rate advantage scales, so the new regime tends to reassert itself unless a home loan is doing heavy lifting. Run both against your own numbers rather than reasoning from a rule of thumb.
What the old regime lets you subtract, and what people over-count
The headline deductions are section 80C up to ₹1.5 lakh — covering EPF, ELSS, PPF, life insurance premiums, principal repayment on a home loan and children's tuition fees — section 80D for health insurance premiums including for parents, section 24(b) for home-loan interest on a self-occupied property, and HRA. The National Pension System adds a further deduction under 80CCD(1B) on top of the 80C limit.
The common over-count is treating the whole 80C limit as available when your own EPF contribution has already consumed a large share of it. If 12% of your basic is going to provident fund, a substantial part of 80C is already used before you buy a single ELSS unit. The second over-count is HRA: the exemption is the smallest of the HRA received, rent paid minus 10% of basic, and 50% of basic in a metro or 40% elsewhere — not simply the rent you pay.
Switching, declaring, and the trap of investing for tax
The new regime is the default. A salaried taxpayer without business income can choose again each assessment year, so nothing you pick now is permanent; taxpayers with business income face restrictions on switching back once they have opted out. Your employer will ask for a declaration early in the financial year to set TDS, but that declaration sets withholding, not your final position — you settle it when you file.
The trap worth naming is investing purely to reduce tax. A five-year lock-in on a product you did not want, bought to save a fraction of the amount invested, is a poor trade. The old regime is the better choice when you already hold the deductions for reasons that stand on their own: you genuinely rent, you genuinely have a home loan, you genuinely insure your parents. Building the deductions to justify the regime is doing it backwards.

Frequently Asked Questions
+Is 12 lakh salary tax free in India?
Under the new regime, taxable income up to ₹12 lakh attracts a full §87A rebate, so tax is effectively zero. With the ₹75,000 standard deduction, a gross salary up to about ₹12.75 lakh can be tax-free — provided you're on the new regime.
+Can I switch between old and new regime every year?
Salaried individuals can choose their regime each financial year. Those with business or professional income face restrictions on switching back to the new regime once they opt out. Always compare both before filing.
+Can I switch regimes every year?
If you are salaried with no business income, yes — you can choose afresh at each assessment year, and the choice you give your employer only sets your TDS rather than binding your return. Taxpayers with business or professional income face tighter rules and generally get one opportunity to switch back after opting out, so the decision carries more weight there.
+Does the new regime allow any deductions at all?
A few. The standard deduction for salaried taxpayers applies, as does the employer's contribution to NPS under 80CCD(2) and certain allowances for specified purposes. What it removes is the large discretionary set — 80C, 80D, HRA, and home-loan interest on a self-occupied property — which is where most people's deduction total actually comes from.
