Income Tax Calculator — what it does
Computes Indian income tax for FY 2025-26 under both the new and the old regime — slabs, the 87A rebate and the 4% cess — so you can see which regime is better for your actual numbers instead of guessing at the form.
How to use Income Tax Calculator
- Enter your gross salary or business income and the deductions you actually claim (80C, 80D, HRA, home-loan interest).
- Switch between the new and old regime and watch the tax figure change.
- Check where the 87A rebate stops applying — the point at which the rebate drops off is often the deciding factor.
- Compare the two results and note which deductions have to be real for the old regime to win.
Worked example: why the regime choice flips
At ₹7.5 lakh income with no investments, the new regime wins because the 87A rebate can wipe the liability out entirely. Add ₹1.5 lakh of 80C plus ₹25,000 of 80D and switch to the old regime and the deductions can pull it ahead. The comparison is the answer, not either number on its own.
