Tax Brackets Guide
The U.S. federal income tax system uses seven marginal tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Your income is taxed in layers, not at a single rate — understanding this is essential for effective tax planning.
A common misconception is that moving into a higher tax bracket means all your income is taxed at that higher rate. In reality, only the income within each bracket is taxed at that bracket's rate. For 2025, a single filer with taxable income of $60,000 would be in the 22% bracket, but their tax calculation is: 10% on the first $11,925 ($1,192.50), plus 12% on income from $11,926 to $48,475 ($4,385.88), plus 22% on income from $48,476 to $60,000 ($2,535.28). Total tax: $8,113.66 — an effective rate of about 13.5%.
The standard deduction for 2025 is $15,000 for single filers, $22,500 for head of household, and $30,000 for married couples filing jointly. This means the first $15,000 of income for a single filer is entirely tax-free before bracket rates even apply. For a married couple earning $94,050 in taxable income after the standard deduction, they could realize up to $94,050 in long-term capital gains at the 0% rate.
Understanding brackets enables strategies like Roth IRA conversions in low-income years. If you have a year with little income (perhaps between jobs or early retirement), you can convert traditional IRA funds to Roth at low marginal rates. Converting $30,000 in a year when your taxable income is $20,000 would cost only about $2,000 in tax — and that money grows tax-free thereafter.

FAQs
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate on your last dollar of income (your highest bracket). Your effective tax rate is total tax paid divided by total income. For a single filer earning $80,000 in 2025, the marginal rate is 22% but the effective rate is roughly 14-16% depending on deductions. This distinction matters when evaluating whether additional income or deductions are worthwhile.
How do tax brackets work for married couples?
Married couples filing jointly have bracket thresholds roughly double those of single filers. This creates a "marriage bonus" for couples with unequal incomes (the higher earner's income is taxed at lower joint rates) and a potential "marriage penalty" for couples with similar high incomes (phase-outs of deductions begin at the same levels).
Are tax brackets adjusted for inflation?
Yes. Each year the IRS adjusts bracket thresholds, the standard deduction, and many other figures for inflation using the Chained Consumer Price Index (C-CPI-U). The 2025 brackets shown above reflect these adjustments. This prevents "bracket creep" where inflation pushes people into higher brackets without real income increases.
