1. What is the Income Tax Formula?

The income tax formula calculates the amount of tax owed based on taxable income, tax rate, and any applicable tax credits. It provides a straightforward way to estimate tax liability before deductions and exemptions.

2. How Does the Calculator Work?

The calculator uses the income tax formula:

Where:

• \( Income \) — Taxable income amount
• \( Rate \) — Applicable tax rate (as decimal)
