Figures are estimates for planning only, not investment or tax advice.
This calculator works out income tax under both the new and the old regime, applies the Section 87A rebate, surcharge and 4% cess, and tells you which regime leaves you with more money.
New regime slabs
Nil up to ₹4 lakh, 5% to ₹8 lakh, 10% to ₹12 lakh, 15% to ₹16 lakh, 20% to ₹20 lakh, 25% to ₹24 lakh and 30% above that. Salaried taxpayers get a ₹75,000 standard deduction, and the 87A rebate of up to ₹60,000 makes tax nil on taxable income up to ₹12 lakh.
Old regime slabs
Nil up to ₹2.5 lakh (₹3 lakh for those over 60, ₹5 lakh over 80), 5% to ₹5 lakh, 20% to ₹10 lakh and 30% above. The standard deduction is ₹50,000 and the 87A rebate is ₹12,500, so tax is nil up to ₹5 lakh of taxable income. Deductions such as 80C, 80D, HRA and home loan interest are only available here.
Which regime wins
The new regime is better for most people unless deductions are large. The break-even sits at roughly ₹8 lakh of total deductions at higher incomes — enter your actual deductions and the calculator shows both figures side by side.
Slabs change with each Budget. Verify against the Income Tax Department before filing, and treat this as an estimate rather than advice.
Frequently asked questions
Is the new regime the default?
Yes. You must opt into the old regime; salaried taxpayers can switch each year, business income cannot switch back freely.
What is the Section 87A rebate?
A rebate that reduces tax to nil below a threshold — ₹60,000 up to ₹12 lakh taxable income in the new regime, ₹12,500 up to ₹5 lakh in the old.
Does this include capital gains?
No. Capital gains are taxed at their own rates and are not part of slab income.
