How the US Tax Bracket System Works
The United States federal income tax system is progressive and marginal. This means only the dollars within each bracket are taxed at that bracket's rate — not your entire income. A common misconception is that earning more could put you in a higher bracket and leave you with less money. That is mathematically impossible: crossing into a higher bracket only affects the dollars above the threshold.
For example, a single filer earning $60,000 in 2025 pays: 10% on the first $11,925 ($1,192.50), 12% on the next $36,550 ($4,386), and 22% on the remaining $11,525 ($2,535.50). Total tax: $8,114. Effective rate: 13.5%, even though the marginal rate is 22%.
2025 Federal Tax Brackets by Filing Status
The IRS adjusts tax brackets annually for inflation. For tax year 2025 (returns filed in 2026), there are seven brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The thresholds vary by filing status:
- Single / Married Filing Separately: 10% up to $11,925 — 37% above $626,350
- Married Filing Jointly: 10% up to $23,850 — 37% above $751,600
- Head of Household: 10% up to $17,000 — 37% above $626,350
Married filing jointly brackets are roughly double the single filer thresholds, which is often called the "marriage bonus" for couples who have disparate incomes. Couples with similar incomes may experience a "marriage penalty" at higher income levels.
Effective Rate vs. Marginal Rate Explained
Your marginal rate is the tax rate on your last dollar of income — the top bracket you enter. Your effective rate is your total tax divided by your total taxable income. These numbers can differ dramatically. A person earning $200,000 (single) has a marginal rate of 32%, but an effective rate of roughly 22%.
Financial decisions should be made based on your marginal rate, not your effective rate. When evaluating whether to contribute to a traditional IRA (pre-tax), make a Roth conversion, take on freelance income, or claim deductions, the marginal rate tells you the actual tax impact of each additional dollar.

How to Reduce Your Federal Tax Bill
Reducing taxable income is the most direct way to lower your federal tax. Key strategies include: maximizing 401(k) and IRA contributions (which reduce taxable income dollar-for-dollar), claiming the standard deduction vs. itemizing (whichever is higher), taking above-the-line deductions for student loan interest and HSA contributions, and timing income and deductions across years when possible. Each $1,000 reduction in taxable income saves you $220 if you're in the 22% bracket, or $320 in the 32% bracket.
