Income Tax Calculator

Free income tax calculator for India — compare old vs new regime for Tax Year 2026-27 with deductions and a clear breakdown.

Last updated 2026-09-17 · FY 2026-27 / AY 2027-28 (slabs unchanged from FY 2025-26)

Age only changes old-regime exemption (₹2.5 lakh / ₹3 lakh / ₹5 lakh). New regime is ₹4 lakh for all ages.

Old regime only — not allowed in new

These reduce old-regime tax. New regime ignores them. Use the HRA calculator if you need the exemption amount.

Taxable ₹14,25,000

Old regime tax

How it works

Tax is computed slab-wise. Rebate (old 87A) is applied, then 4% health and education cess. Old regime also subtracts 80C, HRA, 80D, home-loan interest and extra NPS before slabs.

How to use this calculator

  1. Enter the inputs shown above (amount, rate, tenure, income, or other fields).
  2. Read the live results — they update as you type.
  3. Check the formula, worked example, and assumptions on this page before you decide.

Formula

Tax is computed slab-wise. Rebate (old 87A) is applied, then 4% health and education cess. Old regime also subtracts 80C, HRA, 80D, home-loan interest and extra NPS before slabs.

Worked example

A salaried person with ₹15 lakh income and ₹1.5 lakh of 80C: compare both columns. With no deductions, new regime usually wins; large HRA plus home-loan interest can flip it to old.

Reading the result

Treat the output as a planning figure. Compare it with your sanction letter, payslip, or GST invoice rather than treating it as a filing or a loan offer.

Frequently asked questions

No. Tax Year 2026-27 continues the FY 2025-26 slab rates. New regime remains default, with exemption up to ₹4 lakh and rebate making taxable income up to ₹12 lakh effectively tax-free (salaried, about ₹12.75 lakh before standard deduction).

Assumptions and limits

  • This is a planning estimate. Your lender, employer, or tax officer may use different inputs or rounding.

Results are educational estimates, not tax, legal, investment, or medical advice, and not a loan offer. Verify filings and payments with the official authority or a qualified professional.
