Marginal Rate vs Effective Rate: The Most Common Tax Misconception
If your income puts you in the 22% tax bracket, you don't pay 22% on all your income. Under a progressive system, each bracket's rate only applies to income within that range:
Example: US taxable income of $60,000 (single filer, 2024):
| Income Range | Rate | Tax on This Portion |
|---|
| $0 – $11,600 | 10% | $1,160 |
| $11,601 – $47,150 | 12% | $4,266 |
| $47,151 – $60,000 | 22% | $2,827 |
| Total tax | — | $8,253 |
Effective rate = $8,253 ÷ $60,000 = 13.8% — not 22% (the marginal rate).
US Federal Income Tax Brackets (2024, Single)
| Taxable Income | Rate |
|---|
| $0 – $11,600 | 10% |
| $11,601 – $47,150 | 12% |
| $47,151 – $100,525 | 22% |
| $100,526 – $191,950 | 24% |
| $191,951 – $243,725 | 32% |
| $243,726 – $609,350 | 35% |
| Over $609,350 | 37% |
These are rates on taxable income — income after the standard deduction ($14,600 for single filers in 2024) and other deductions.

Frequently Asked Questions
Which matters more — marginal or effective rate?
Both matter in different contexts. Use your marginal rate to evaluate decisions at the margin — taking on a side job, making a pre-tax retirement contribution, timing a bonus. Use your effective rate to compare your overall tax burden year over year or across income levels.
Does getting a raise push all my income into a higher bracket?
No — only the income above the bracket threshold gets taxed at the higher rate. A raise that pushes you from the 22% to the 24% bracket means only the income above $100,525 is taxed at 24%. Everything below stays at the lower rates. A raise never makes you worse off after tax.
What's the difference between income tax and total tax burden?
Income tax is just one piece. Your full tax burden includes: federal income tax + state income tax + Social Security (6.2%) + Medicare (1.45%) + any local taxes. The combined marginal rate can exceed 40% for high earners in high-tax states like California or New York.
