What Is Income Tax Computation?

Income tax computation is the process of working out how much tax you must pay for a financial year. You add up your income from all sources, subtract the deductions you are allowed, apply the tax slab rates, and add cess. The final figure is your tax payable. If you have already paid more through TDS or advance tax, the extra amount comes back to you as a refund.

A correct computation tells you the right tax to pay, the right ITR to file, and whether the old or new tax regime saves you more money.

What is the Formula to Calculate Income Tax?

Use this order every time:

1. Add income under all five heads to get Gross Total Income
2. Subtract deductions under Chapter VI-A to get Total Taxable Income
3. Apply the slab rates to get Tax on Total Income
4. Subtract the rebate under Section 87A, if eligible
5. Add surcharge, if income is high
6. Add 4% Health and Education Cess
7. Subtract TDS, advance tax, and self-assessment tax paid
8. The result is your Tax Payable or Refund

What Are the Five Heads of Income?

Every rupee you earn falls under one of these heads.

How is Tax Computed on Capital Gains?

Capital gains are taxed at special rates, not at slab rates.

Rates can change with each Budget, so check the latest rules before filing.
