How it works
Taxable income = gross − standard deduction − allowed deductions. Slab tax + 4% cess, with 87A rebate up to ₹60,000 (new regime, taxable ≤ ₹12L).
Example: ₹15L salary, new regime → taxable ₹14.25L → tax ₹97,500.
Frequently Asked Questions
Which tax regime is better for me?
It depends on your income and how many deductions you claim. If you claim deductions like 80C, 80D and 24(b) that add up, the old regime can be cheaper. Otherwise the new regime's lower slab rates usually win. This calculator compares both side by side.
What are the new regime tax slabs for FY 2026-27?
The slabs are: up to ₹4L nil, ₹4–8L at 5%, ₹8–12L at 10%, ₹12–16L at 15%, ₹16–20L at 20%, ₹20–24L at 25% and above ₹24L at 30%. A ₹75,000 standard deduction applies, and the ₹60,000 rebate under section 87A makes income up to ₹12L effectively tax-free.
Is income up to ₹12 lakh really tax-free?
Under the new regime, yes. The ₹60,000 rebate under section 87A cancels the tax for taxable income up to ₹12L. Your gross salary can be up to ₹12.75L because of the ₹75,000 standard deduction.
Do the old and new regime give the same standard deduction?
No. The new regime gives ₹75,000 and the old regime gives ₹50,000. The old regime also allows deductions such as 80C, 80D and home loan interest under 24(b), which the new regime does not.
Does this calculator include cess and surcharge?
It includes the 4% health and education cess. Surcharge for incomes above ₹50 lakh and marginal relief are not included, so very high earners should check the full calculation with a professional.
