Income Tax Calculator — New vs Old Regime
Enter your income once and see the tax, slab by slab, under both the new and old regimes — with a straight answer on which one saves you more.
On ₹15,00,000/yr, the New regime costs you less — ₹97,500 in tax versus ₹2,10,600, a difference of ₹1,13,100/yr. The new regime applies a flat ₹75,000 standard deduction and taxes what's left in slabs from 5% to 30%, with a full rebate if taxable income is under ₹12,00,000. The old regime applies a ₹50,000 standard deduction plus whatever you claimed in other deductions, then taxes the rest in wider slabs — it only wins once your deductions are large enough to offset its higher rates.
