Every Indian salaried individual faces the same annual question: which tax regime saves more money — the Old Regime with its web of deductions, or the New Regime with its simpler slabs and lower rates? The answer depends on your specific income level, HRA component, home loan interest, Section 80C investments, and other deductions you actually claim. Running the numbers manually against both sets of slabs, applying the right rebates, and comparing totals is error-prone and time-consuming. The Utility Spark Income Tax Calculator does this in seconds. Enter your gross annual income, select the financial year, and indicate whether you are claiming major deductions (80C, 80D, HRA). The calculator applies the correct tax slabs for both regimes, accounts for the standard deduction, applies Section 87A rebate where applicable, and adds health and education cess — presenting side-by-side regime comparison results so you can see which option leaves more money in your pocket. All calculations are client-side; your salary and financial details are never transmitted or stored.

Why use our tool?
Old Regime vs New Regime Side-by-Side Comparison
The single most useful feature for most users: the calculator shows your estimated tax liability under both regimes simultaneously. Instead of running two separate calculations, you see the difference in absolute rupees at a glance, with a clear recommendation for which regime saves more for your specific income and deduction profile.
FY 2024-25 Slabs Including Updated New Regime
The New Tax Regime was updated in Budget 2023 with revised slabs effective FY 2023-24 onwards, and the basic exemption limit was raised to ₹3 lakh. The calculator reflects current slabs: 0% up to ₹3L, 5% for ₹3L-₹7L, 10% for ₹7L-₹10L, 15% for ₹10L-₹12L, 20% for ₹12L-₹15L, and 30% above ₹15L under the New Regime. Old Regime slabs and all applicable deductions are also current.
Section 87A Rebate Applied Automatically
Taxpayers with net taxable income up to ₹7 lakh under the New Regime (and ₹5 lakh under the Old Regime) get a 100% tax rebate under Section 87A, making their net tax liability zero. This rebate is automatically calculated and displayed, which many manual calculations miss.
Health and Education Cess Included
The final tax liability includes the 4% health and education cess applied to the base income tax amount. This is frequently omitted in simplified calculators, making their output misleadingly lower than actual liability.
Your Income Data Is Never Shared
Salary and income information is personal financial data. This calculator runs entirely in your browser — no salary figure, deduction amount, or tax result is transmitted to Utility Spark servers or any third party. The calculation is as private as using a physical calculator.
How it works
Enter your gross annual income (CTC or total annual salary before any deductions).
Select the financial year (default: FY 2024-25).
Enter your major deductions if you are on the Old Regime: Section 80C investments (max ₹1.5 lakh), HRA exemption claimed, 80D health insurance premium, home loan interest (Section 24b), and any other deductions.
The calculator simultaneously displays tax liability under both Old and New Regime.
Review the comparison to identify which regime results in lower tax for your specific profile.
