Pick the regime that actually costs you less
Every slab, the surcharge band, health and education cess and the section 87A rebate are shown as separate lines so you can check the arithmetic rather than trust a single number.
Most Chapter VI-A deductions such as 80C, 80D and HRA exemption apply only under the old regime. The comparison handles that automatically.
Frequently asked questions
Which regime should I choose?
It depends almost entirely on how much you claim in deductions. The new regime has lower rates but disallows most exemptions, so it usually wins for people with few deductions. The old regime tends to win once your combined 80C, 80D, HRA and home loan interest claims get large. This calculator computes both and names the cheaper one.
Is the standard deduction included?
Yes. A standard deduction of Rs 75,000 is applied automatically under the new regime and Rs 50,000 under the old regime for salaried income. You do not need to enter it as a deduction.
What is the section 87A rebate?
It is a rebate that reduces your tax to zero if your taxable income falls below a threshold — Rs 7,00,000 under the new regime and Rs 5,00,000 under the old regime. The calculator applies it automatically, including marginal relief just above the new-regime threshold.
Does this handle surcharge on high incomes?
Yes. Surcharge is applied at 10%, 15%, 25% and 37% for the respective income bands, capped at 25% under the new regime, and health and education cess of 4% is added on top of tax plus surcharge.
Is this a substitute for filing advice?
No. It is an estimate covering the common salaried case. Capital gains taxed at special rates, business income, clubbing provisions and relief under section 89 are not modelled — consult a chartered accountant for anything beyond a straightforward salary.
