How Tax Brackets Actually Work: Marginal vs Effective Rate
A lot of people believe that if a raise pushes them into a higher tax bracket, their entire income suddenly gets taxed at that higher rate — and that this could somehow leave them with less money than before. That's not how the U.S. federal income tax system works. It's a marginal tax system: each bracket only applies to the slice of income that falls within it, not to everything you earn.
2026 federal tax brackets (Single)
| Rate | Income range |
|---|---|
| 10% | $0 – $12,400 |
| 12% | $12,401 – $50,400 |
| 22% | $50,401 – $105,700 |
| 24% | $105,701 – $201,775 |
| 32% | $201,776 – $256,225 |
| 35% | $256,226 – $640,600 |
| 37% | $640,601+ |
2026 federal tax brackets (Married Filing Jointly)
| Rate | Income range |
|---|---|
| 10% | $0 – $24,800 |
| 12% | $24,801 – $100,800 |
| 22% | $100,801 – $211,400 |
| 24% | $211,401 – $403,550 |
| 32% | $403,551 – $512,450 |
| 35% | $512,451 – $768,700 |
| 37% | $768,701+ |
Brackets also exist for Head of Household filers, with thresholds between the Single and Married Filing Jointly figures. All thresholds are adjusted for inflation each year under IRS Revenue Procedure guidance.
A worked example: $60,000 salary (Single)
Here's how a single filer earning $60,000 in taxable income actually gets taxed under the 2026 brackets above — notice each bracket only taxes the income inside its own range:
| Bracket | Taxable amount in this bracket | Tax owed |
|---|---|---|
| 10% (up to $12,400) | $12,400 | $1,240.00 |
| 12% ($12,401–$50,400) | $38,000 | $4,560.00 |
| 22% ($50,401–$60,000) | $9,600 | $2,112.00 |
| Total | $60,000 | $7,912.00 |
This person's marginal tax rate is 22% — that's the rate on their last dollar earned. But their effective tax rate is $7,912 ÷ $60,000 = about 13.2%. That gap between marginal and effective rate exists for everyone, and it's why headlines about "being in the 22% bracket" overstate how much of your income is actually taxed at that rate.
Why a raise never leaves you worse off
Because only the income above a threshold is taxed at the higher rate, crossing into a new bracket can never reduce your total after-tax pay. A raise that pushes part of your income into the 24% bracket, for example, still leaves 100% of your previous income taxed exactly as before — only the new, additional income is taxed at the higher rate. You always keep a majority of any raise, no matter which bracket it lands in.
2026 standard deduction
| Filing status | Standard deduction |
|---|---|
| Single | $16,100 |
| Married Filing Jointly | $32,200 |
| Head of Household | $24,150 |
The standard deduction reduces your taxable income before brackets are applied — it's why "taxable income" in the tables above is usually lower than your gross salary.
Second example: $100,000 of taxable income (Single)
Using the same 2026 brackets, a single filer with $100,000 of taxable income pays:
| Bracket | Taxable amount in this bracket | Tax owed |
|---|---|---|
| 10% | $12,400 | $1,240.00 |
| 12% | $38,000 | $4,560.00 |
| 22% ($50,401–$100,000) | $49,600 | $10,912.00 |
| Total | $100,000 | $16,712.00 |
The marginal rate is 22%, but the effective rate is about 16.7%. Notice that moving from $60,000 to $100,000 of taxable income raised the effective rate by only about 3.5 percentage points, because most of the extra income is taxed at 22%, and the first $50,400 is still taxed at the lower rates.
What a raise really does to your take-home pay
Suppose your taxable income goes from $50,000 to $55,000 as a single filer. The first $400 of the raise (up to $50,400) is taxed at 12% and the remaining $4,600 is taxed at 22%, so the extra federal tax is about $1,060. You keep about $3,940 of the $5,000 raise, or roughly 79%. You do not lose money by moving into the higher bracket, and your original $50,000 is taxed exactly as before. State and payroll taxes, which this guide does not cover, also apply.
From gross salary to taxable income
The tables above use taxable income, which is lower than your salary. A single filer earning $75,000 who takes the 2026 standard deduction of $16,100 has $58,900 of taxable income. The federal tax on that is about $7,670, which is about 10.2% of the $75,000 salary and about 13.0% of the $58,900 taxable income. Pre-tax contributions to a 401(k) or HSA can reduce taxable income further, which is one reason people use them. Check the current rules for your accounts.
Marginal vs. effective rate: which should you use?
- Marginal rate is the rate on your next dollar of income. Use it to judge a raise, a bonus, a side job or a pre-tax deduction.
- Effective rate is your total tax divided by your income. Use it to see how much of your income actually goes to federal income tax.
Common mistakes about tax brackets
- Thinking a raise can lower your pay. It cannot, because only the dollars above a threshold move to the higher rate.
- Applying your bracket rate to all your income. Only the part above the bracket start is taxed at that rate.
- Mixing up gross and taxable income. Deductions are subtracted first, so brackets apply to a smaller number than your salary.
- Forgetting other taxes. Social Security and Medicare payroll taxes and state taxes are separate from federal income tax brackets. See understanding your paycheck for how those fit in.
- Ignoring capital gains. Long-term investment gains are generally taxed under a different rate schedule than wages.
