1. What is Income Tax Calculation?

Income tax calculation determines the amount of tax an individual or entity owes based on their taxable income, applicable tax rate, and any eligible tax credits. It's a fundamental financial calculation used worldwide.

The calculator uses the basic income tax formula:

Where:

• \( Taxable\ Income \) — Total income subject to taxation ($)
• \( Tax\ Rate \) — Applicable tax rate (%)
• \( Credits \) — Tax credits that reduce tax liability ($)

Explanation: The formula multiplies taxable income by the tax rate (converted from percentage to decimal) and then subtracts any applicable tax credits.
