How to use the Income Tax Calculator in a few steps
The Income Tax Calculator is designed so a typical tax estimate takes under a minute. Follow these steps.
Step 1: Enter your gross income
Type your total annual income from salary, business, or other sources into the income field. This is your total income before any deductions.
Step 2: Add deductions
Enter deductions you can claim under the old regime — standard deduction, 80C (up to 1.5 lakh), 80D (health insurance), HRA exemption, and others. These reduce your taxable income under the old regime but are not available under the new regime.
Step 3: Read the side-by-side comparison
The tool shows the tax liability under both regimes with the 87A rebate and 4% health and education cess applied. You can instantly see which regime gives you the lower number.
The comparison updates live as you change your income or deductions, so you can test multiple scenarios in seconds.
Understanding the result
- The new regime offers lower slab rates but does not allow most deductions
- The old regime lets you claim HRA, 80C, 80D, and other exemptions at higher slab rates
- The 87A rebate zeros out your tax before cess if you are within the threshold
