2024 Federal Income Tax Brackets Explained (With Examples)

🔑

Progressive ≠ Flat Rate

Common misconception: "I'm in the 22% bracket, so I pay 22% on everything." Wrong. Only the income within that bracket is taxed at 22%. Your effective rate is always lower.

22%

Marginal rate (last dollar)

12.4%

Effective rate (what you actually pay)

💡

Marginal vs Effective Rate

Your marginal rate (22%) applies to your last dollar. Your effective rate (12.4%) is your actual tax ÷ total income. The effective rate is always lower.

💼 Don't Forget FICA

On top of federal income tax, you pay:

🏛️

FICA on $85,000 Income

Social Security (6.2%):$5,270

Medicare (1.45%):$1,233

Total FICA

$6,503

✅

Max Your 401(k) — $23,000/year

FICA adds another $6,500+ — don't forget this in take-home calculations
401(k) + IRA + HSA can reduce your taxable income by $34,000+
