US Federal Tax Brackets 2025, Explained
Every tax season, the same myth refuses to die: “I got a raise and it pushed me into a higher bracket, so I take home less.” That is not how brackets work. Here is what actually happens to your paycheck.
The one idea that matters: marginal vs effective
The US has a progressive tax system: income is taxed in layers, and each layer is taxed at its own rate. Only the dollars inside a bracket are taxed at that bracket’s rate. Your marginal rate is the rate on your last dollar; your effective rate — what you really pay overall — is always lower.
2025 federal brackets (single filer)
| Tax rate | Taxable income |
|---|---|
| 10% | $0 – $11,925 |
| 12% | $11,926 – $48,475 |
| 22% | $48,476 – $103,350 |
| 24% | $103,351 – $197,300 |
| 32% | $197,301 – $250,525 |
| 35% | $250,526 – $626,350 |
| 37% | Over $626,350 |
10% on first $11,925 = $1,192.50
12% on next $36,550 = $4,386
22% on remaining $41,525 = $9,135.50
Total ≈ $14,714 → effective rate ~16.3%, even though the marginal rate is 22%.
Don’t forget the standard deduction
Before brackets even apply, the standard deduction shields part of your income: $15,000 for single filers and $30,000 for married couples filing jointly in 2025. So a single filer earning $90,000 has only about $75,000 of taxable income. You can itemize instead if your deductions are larger, but most people take the standard amount.
What the brackets don’t cover
Federal income brackets are only one slice of the tax pie. Long-term capital gains get their own preferential rates (0%, 15%, or 20% for most people in 2025), Social Security and Medicare take another 7.65% straight off your paycheck, and state taxes pile on top. That is why two people with the same salary can owe very different totals — the type of income matters almost as much as the amount.

Will earning more ever lower my take-home pay?
Not from federal brackets alone — only the income above each threshold is taxed at the higher rate. (Benefit phase-outs in specific programs can create edge cases, but a straight raise never costs you money.)
What is the difference between a deduction and a credit?
A deduction shrinks the income that gets taxed; a credit shrinks the tax bill itself, dollar for dollar. A $1,000 credit is worth more than a $1,000 deduction for almost everyone.
Do these brackets include state taxes?
No — these are federal only. State income tax is separate and ranges from 0% (Texas, Florida, and others) to over 13% in California. Our estimator covers the federal side.
