How US income tax brackets work
The United States uses a progressive tax system — as your income rises, higher rates apply only to the portion of income above each threshold. This is the most commonly misunderstood aspect of US taxes: earning more never causes your entire income to be taxed at a higher rate.
For example, a single filer in 2024 pays 10% on the first $11,600, 12% on income from $11,601 to $47,150, 22% on income from $47,151 to $100,525, and so on. If you earn $95,000, your top bracket is 22% — but most of your income is taxed at 10% and 12%. Your effective rate (actual tax ÷ gross income) will be much lower than your marginal rate.
Your marginal rate is the rate on your last dollar of income — and the rate that applies to any additional income you earn (bonus, freelance, etc.). Understanding your marginal rate helps you make informed decisions about retirement contributions, deductions, and timing of income.

Tax Bracket FAQs
What is the difference between marginal and effective tax rate?
Your marginal rate is the rate applied to your last dollar of taxable income — the bracket you're in. Your effective rate is total federal tax divided by gross income. Because of the progressive system, the effective rate is always lower than the marginal rate. Someone in the 22% bracket typically has an effective rate of 12–15%.
Does a raise push all my income into a higher bracket?
No — this is a very common misconception. Only the income above the bracket threshold is taxed at the higher rate. If a raise pushes $5,000 into the 22% bracket, only that $5,000 is taxed at 22%. Your income below the threshold continues to be taxed at lower rates. You will never take home less money after a raise.
How do deductions reduce my tax?
Deductions reduce your taxable income before tax is calculated. A $10,000 deduction for someone in the 22% bracket saves $2,200 in federal taxes. The standard deduction ($14,600 single / $29,200 MFJ in 2024) is available to everyone. Itemizing is worth it only if your qualifying expenses exceed the standard deduction.
What are FICA taxes?
FICA (Federal Insurance Contributions Act) taxes fund Social Security (6.2% up to $168,600) and Medicare (1.45% on all wages, plus an additional 0.9% above $200K single / $250K MFJ). Unlike income taxes, FICA applies to gross wages before any deductions. Your employer matches the 6.2% and 1.45% portions. Self-employed individuals pay both sides (15.3% total — see the 1099 vs. W-2 calculator).
Terminology
Marginal Tax Rate
The tax rate that applies to your next dollar of income. Determined by which bracket your taxable income falls into. Relevant for decision-making: a $1,000 pre-tax 401(k) contribution saves you $220 in federal taxes if you're in the 22% bracket.
Effective Tax Rate
Total tax paid divided by gross income. Your real-world tax burden as a percentage. Always lower than your marginal rate due to progressive brackets and deductions. The number most useful for comparing tax burden across income levels.
Standard Deduction
A flat deduction available to all taxpayers regardless of expenses. 2024 amounts: $14,600 (single/MFS), $29,200 (MFJ), $21,900 (Head of Household). Reduces gross income to arrive at taxable income. About 90% of filers use the standard deduction.
Taxable Income
Gross income minus above-the-line adjustments (retirement, HSA, student loan interest) minus your deduction (standard or itemized). This is the figure to which tax brackets are applied — not your gross income.
Above-the-Line Deductions
Deductions subtracted from gross income to calculate Adjusted Gross Income (AGI) before the standard or itemized deduction. Include traditional IRA/401(k) contributions, HSA contributions, student loan interest, and self-employed health insurance. Available regardless of whether you itemize.
Tax Credits vs. Deductions
Deductions reduce taxable income; credits reduce tax owed dollar-for-dollar. A $1,000 deduction in the 22% bracket saves $220. A $1,000 tax credit saves $1,000. Credits are generally more valuable — common ones include the Child Tax Credit ($2,000/child), EITC, Child & Dependent Care Credit, and education credits.
