Tax Bracket Calculator (2024 US)

Formula

The 2024 single-filer brackets are: 10% on income $0–$11,600; 12% on $11,601–$47,150; 22% on $47,151–$100,525; 24% on $100,526–$191,950; 32% on $191,951–$243,725; 35% on $243,726–$609,350; 37% on income above $609,350. Each bracket applies only to the income within its range. For example, on $75,000 income: 10% of the first $11,600 + 12% of the next $35,550 + 22% of the remaining $27,850. The effective rate is total tax divided by total income — it's always lower than the marginal rate.

Marginal vs. effective tax rate: the most common tax misconception

The single most common tax misconception is believing that entering a higher tax bracket means all of your income gets taxed at the higher rate. This is incorrect. The U.S. uses a marginal (progressive) tax system, where each bracket rate applies only to the income within that range.

If you earn $50,000 as a single filer in 2024, your marginal rate is 22% — but your effective rate is much lower. You pay 10% on the first $11,600, 12% on the next $35,550, and 22% on only the remaining $2,850. Your total tax is approximately $6,617, an effective rate of about 13.2%. Understanding this means you should never turn down a raise 'because it puts me in a higher bracket' — only the additional income above the bracket threshold is taxed at the higher rate.

The effective rate is the more meaningful number for financial planning because it tells you what percentage of your total income goes to federal taxes. The marginal rate tells you the rate on your next dollar of income — useful for evaluating the tax impact of additional income, deductions, or contributions to tax-deferred accounts.

What's not included in this calculation

This calculator computes federal income tax based on taxable income using 2024 single-filer brackets. It does not account for several factors that affect your actual tax bill:

Standard deduction: In 2024, the standard deduction for single filers is $14,600. If you enter your gross income, subtract the standard deduction first to get your taxable income. If you itemize deductions, use your total itemized deductions instead.

State and local taxes: Most states have their own income tax, ranging from 0% (Texas, Florida, etc.) to over 13% (California). This calculator only covers federal taxes.

FICA taxes: Social Security (6.2% up to $168,600) and Medicare (1.45%) are payroll taxes separate from income tax, representing an additional ~7.65% for most employees.

Credits and deductions: Tax credits (child tax credit, education credits, earned income credit) directly reduce tax owed and can be substantial for qualifying taxpayers.

Tax planning strategies that reduce taxable income

The most effective way to reduce your tax burden is to reduce taxable income through pre-tax contributions. Contributing to a traditional 401(k) or traditional IRA reduces your taxable income dollar-for-dollar. At a 22% marginal rate, every $1,000 contributed to a traditional 401(k) saves $220 in federal taxes immediately — in addition to the long-term compounding benefit.

Health Savings Accounts (HSAs) offer triple tax advantages: contributions are pre-tax, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. For eligible high-deductible health plan participants, maxing an HSA ($4,150 for individuals in 2024) is one of the most tax-efficient moves available.

For investors, tax-loss harvesting — selling investments at a loss to offset capital gains — can meaningfully reduce taxable income in years with significant investment activity. Long-term capital gains (assets held over one year) are taxed at preferential rates (0%, 15%, or 20%) rather than ordinary income rates, making the holding period an important tax consideration for non-retirement investments.
