Income Tax Calculator
The Income Tax Calculator calculates exact, real-time domain outputs in active voice. The Income Tax Calculator computes annual and monthly income tax liability with a side-by-side comparison of progressive tax slabs (including the latest Indian New Tax Regime with ₹75,000 standard deduction and Section 87A rebate vs. Old Tax Regime with 80C/80D/HRA deductions). Easily adjust gross salary and deductions to discover which regime minimizes your tax outflow.

Income Tax Calculator Mathematical Formula
T_{\text{total}} = \left(\sum_{k} \max(0, \min(Y_{\text{tax}}, U_k) - L_k) \cdot r_k - R_{87A}\right) \times 1.04Income Tax Calculator Worked Example
Gross annual salaried income of 1,500,000 with 200,000 in Old Regime deductions (80C + 80D).
- New Regime Taxable Income = 1,500,000 - 75,000 (Standard Deduction) = 1,425,000.
- New Regime Slab Tax on 1,425,000 = 127,500; plus 4% Cess (5,100) = 132,600 total tax.
- Old Regime Taxable Income = 1,500,000 - 50,000 (Std) - 200,000 (Deductions) = 1,250,000.
- Old Regime Slab Tax on 1,250,000 = 187,500; plus 4% Cess (7,500) = 195,000. New Regime saves 62,400.
Unless your total exemptions and deductions (HRA + Home Loan 24b + 80C + 80D) exceed roughly 375,000 to 425,000, the New Tax Regime generally results in a lower tax liability and higher monthly take-home pay.

Income Tax Calculator Frequently Asked Questions
Q: Which tax regime is the default in India?
The New Tax Regime (Section 115BAC) is the default regime. However, salaried individuals without business income can switch between the New and Old Tax Regime every financial year when filing their Income Tax Return (ITR).
Q: What is the Effective Tax Rate vs. Marginal Tax Rate?
Your marginal tax rate is the percentage applied to the highest slab your income reaches (e.g., 30%), whereas your effective tax rate is your total tax divided by your gross income (which is always lower due to progressive lower slabs).
