1. What is Federal Income Tax?

Federal income tax is a tax levied by the U.S. government on your annual earnings. The amount you owe depends on your taxable income, filing status, deductions, and credits.

2. How Does the Calculator Work?

The calculator uses the basic federal tax formula:

Where:

• \( Taxable\ Income \) — Your adjusted gross income minus deductions ($)
• \( Federal\ Tax\ Rate \) — Your marginal tax rate (decimal)
• \( Credits \) — Tax credits you qualify for ($)

Explanation: This simplified calculation multiplies your taxable income by your tax rate, then subtracts any tax credits you're eligible for.

3. Importance of Tax Calculation

Details: Accurate tax estimation helps with financial planning, withholding adjustments, and avoiding underpayment penalties. It's essential for budgeting and ensuring you don't owe unexpected amounts at tax time.

4. Using the Calculator

Tips: Enter your taxable income in dollars, federal tax rate as a percentage (e.g., 22 for 22%), and any tax credits in dollars. The calculator will estimate your federal tax liability.
