How are federal income taxes calculated?

Federal income tax uses a progressive tax bracket system, meaning different portions of your income are taxed at different rates.

How Progressive Brackets Work

Your income is divided into brackets, and each bracket is taxed at its own rate. You only pay the bracket rate on income within that bracket, not your entire income.

2024 Federal Tax Brackets

Tax RateSingle FilersMarried Filing Jointly
10%Up to $11,600Up to $23,200
12%$11,601 - $47,150$23,201 - $94,300
22%$47,151 - $100,525$94,301 - $201,050
24%$100,526 - $191,950$201,051 - $383,900
32%$191,951 - $243,725$383,901 - $487,450
35%$243,726 - $609,350$487,451 - $731,200
37%Over $609,350Over $731,200

Example Calculation

If you're single earning $60,000:

  • First $11,600 taxed at 10% = $1,160
  • Next $35,550 taxed at 12% = $4,266
  • Remaining $12,850 taxed at 22% = $2,827
  • Total tax: $8,253 (effective rate: 13.8%)

What is the standard deduction?

The standard deduction is an amount you can subtract from your income before calculating taxes, reducing your taxable income.

2024 Standard Deduction Amounts

Filing StatusStandard Deduction
Single$14,600
Married Filing Jointly$29,200
Married Filing Separately$14,600
Head of Household$21,900

Standard vs. Itemized Deductions

You can choose either:

Standard Deduction (easier):

  • No documentation required
  • Fixed amount based on filing status
  • Best for most taxpayers

Itemized Deductions (more complex):

  • Requires documentation
  • Includes mortgage interest, charitable donations, medical expenses, state taxes
  • Worth it if total itemized deductions exceed standard deduction

Recommendation: Take whichever is higher. Most taxpayers (about 90%) use the standard deduction.

When do tax brackets change?

2023$13,850+$900
2024$14,600+$750

Major Tax Law Changes

Significant changes to tax rates, brackets, or deductions require congressional action through new tax legislation.

Recent Example: Tax Cuts and Jobs Act (2017) made major changes including:

  • New bracket rates
  • Doubled standard deduction
  • Limited state/local tax deductions
  • Most provisions expire after 2025

Stay Informed: Check IRS.gov annually for updated brackets and limits.
