Federal Income Tax Basics

The federal income tax is a progressive tax system that means higher income earners pay a higher percentage of their income in taxes. The tax is calculated by applying different tax rates to different portions of your income.

For example, if you earn $50,000 and your taxable income is $46,350 (after standard deduction), the first $9,950 is taxed at 10%, the next $30,400 at 12%, and the remaining $5,950 at 22%.

Mortgage interest deduction
State and local taxes
Student loan interest
Retirement contributions
Charitable donations
Earned income credit (EIC)
American Opportunity credit (AOTC)

Taxable Income Formula

Taxable Income = Gross Income - Deductions - Exemptions

Federal Income Tax = Taxable Income × Tax Rate

Worked Examples

Example 1: Single filer with $50,000 income

Taxable Income = $50,000 - $13,850 (standard deduction) = $36,150

Tax Calculation:

$9,950 × 10% = $995
$30,400 × 12% = $3,648
$5,750 × 22% = $1,265

Total Federal Income Tax = $995 + $3,648 + $1,265 = $5,908

Example 2: Married filing jointly with $100,000 income

Taxable Income = $100,000 - $27,700 = $72,300

Tax Calculation:

$22,000 × 10% = $2,200
$67,450 × 12% = $8,094

Total Federal Income Tax = $2,200 + $8,094 = $10,294
