A worked example, end to end
Scenario
Salaried professional, age 32, gross annual salary ₹18,00,000. HRA paid ₹2,40,000. 80C investments ₹1,50,000. Home loan interest ₹1,80,000.
New regime
- Gross: ₹18,00,000.
- Standard deduction: ₹75,000. Taxable: ₹17,25,000.
- Tax across slabs: ₹0 + ₹20,000 + ₹40,000 + ₹60,000 + ₹80,000 + ₹31,250 = ₹2,31,250.
- Plus 4% cess: ₹9,250. Total: ₹2,40,500.
Old regime
- Gross: ₹18,00,000. Standard deduction: ₹50,000.
- Less HRA exemption: ₹2,40,000 (assumed full).
- Less 80C: ₹1,50,000. Less Section 24: ₹1,80,000.
- Taxable: ₹11,80,000. Tax: ₹1,67,000 + cess ₹6,680 = ₹1,73,680.
Pick
Old regime wins by ₹66,820 here because the three big deductions (HRA + 80C + Section 24) exceed the new regime's lower-slab advantage.

How income tax is calculated
New regime (FY 2025-26)
Per Budget 2025, the new regime slabs are:
- Up to ₹4,00,000, Nil
- ₹4,00,001 to ₹8,00,000, 5%
- ₹8,00,001 to ₹12,00,000, 10%
- ₹12,00,001 to ₹16,00,000, 15%
- ₹16,00,001 to ₹20,00,000, 20%
- ₹20,00,001 to ₹24,00,000, 25%
- Above ₹24,00,000, 30%
Standard deduction of ₹50,000 applies. Section 87A rebate makes tax nil for taxable income up to ₹12,00,000. Health and Education cess at 4% of total tax. Surcharge applies above ₹50L taxable income (not in this calculator).
Old regime (FY 2025-26)
Slabs for individuals below 60 years:
- Up to ₹2,50,000, Nil
- ₹2,50,001 to ₹5,00,000, 5%
- ₹5,00,001 to ₹10,00,000, 20%
- Above ₹10,00,000, 30%
Standard deduction of ₹50,000 applies. 80C deductions up to ₹1,50,000, 80D health insurance, HRA exemption, Section 24 home loan interest up to ₹2,00,000 for self-occupied property all reduce taxable income. Section 87A rebate of up to ₹12,500 for taxable income up to ₹5,00,000.
Which regime?
The new regime is simpler and lower-rate but allows fewer deductions. The old regime can be better if you have significant 80C investments, HRA exemption and home-loan interest. The break-even depends on your deduction profile; the calculator shows both side by side. From FY 2023-24, the new regime is the default.
Income tax FAQ
Common questions.
Which regime should I pick?
Run the numbers in both. As a rough rule, if your total deductions (80C + HRA + Section 24 + others) are under ₹2,50,000 the new regime usually wins. With heavy deductions (₹3L+) the old regime can still beat. The calculator shows both; pick whichever gives you the lower tax. From FY 2023-24, the new regime is the default, declare the old regime via Form 10-IEA if you prefer it.
What is the Section 87A rebate?
A direct reduction in tax payable for low and middle income taxpayers. Under the new regime (FY 2025-26), the rebate makes tax nil for taxable income up to ₹12,00,000. Under the old regime, the rebate is up to ₹12,500 for taxable income up to ₹5,00,000.
Does this calculator handle capital gains?
Not directly. Capital gains have separate rates (10% LTCG above ₹1L for equity, 20% with indexation for other LTCG, 15% STCG on equity, slab rates for other STCG). For salaried taxpayers, the calculator handles your salary income; capital gains tax should be added separately.
What about surcharge?
Surcharge applies above ₹50L taxable income: 10% on tax for ₹50L-1Cr, 15% for ₹1Cr-2Cr, 25% for ₹2Cr-5Cr, and 37% for above ₹5Cr (capped at 25% under the new regime). The calculator does not include surcharge, for high-income taxpayers, factor it in separately.
Does this work for senior citizens?
For the old regime, the calculator supports below-60, senior citizen (60-79) and super-senior citizen (80+) age groups with the right basic exemption limits (₹2.5L / ₹3L / ₹5L). The new regime has the same slabs for all age groups.
How accurate is this for actual filing?
Accurate for the basic salary case. For complex cases (multiple income sources, capital gains, foreign income, presumptive taxation, business income with depreciation) consult your CA. For your books and statutory filings on the business side, OneFinOps automates the rest.
