Tax Bracket

The range of income taxed at a specific marginal rate in a progressive tax system. Moving into a higher bracket only affects income within that bracket, not all income.

Tax Bracket

A tax bracket is a range of income subject to a specific marginal tax rate within a progressive income tax system. The United States uses seven federal income tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37% as of 2024), where higher-income portions are taxed at progressively higher rates.

The Critical Misconception: Brackets Are Marginal

The most common misunderstanding about tax brackets is that moving into a higher bracket means ALL your income is taxed at that rate. That is false.

How it actually works:

  • Only income WITHIN each bracket is taxed at that bracket's rate
  • Income in the first bracket is always taxed at 10% — regardless of your total income
  • "Moving into the 32% bracket" means only the dollars above the 32% threshold are taxed at 32%

2024 Federal Tax Brackets (Single filers):

| Tax Rate | Income Range | |----------|-------------| | 10% | $0 – $11,600 | | 12% | $11,601 – $47,150 | | 22% | $47,151 – $100,525 | | 24% | $100,526 – $191,950 | | 32% | $191,951 – $243,725 | | 35% | $243,726 – $609,350 | | 37% | Over $609,350 |

Marginal Rate vs. Effective Tax Rate

Marginal rate: The rate on your last dollar of income — i.e., the bracket you're "in."

Effective tax rate: Your total tax bill divided by total income. Always lower than your marginal rate because lower brackets capture your first dollars of income.

A single filer with $80,000 in taxable income:

  • Pays 10% on first $11,600 = $1,160
  • Pays 12% on $11,601–$47,150 = $4,266
  • Pays 22% on $47,151–$80,000 = $7,227
  • Total tax: $12,653
  • Effective rate: 15.8% (not 22%)

Standard Deduction

The federal standard deduction ($14,600 for single filers in 2024, $29,200 married filing jointly) reduces your taxable income before brackets are applied. Most taxpayers take the standard deduction rather than itemizing.

State Income Taxes

Most states have their own income tax systems, often with different brackets and rates. Nine states have no income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming.
