Marginal vs Effective Tax Rate Explained
One of the most common money myths is that a raise can push you into a higher tax bracket and leave you with less money. It cannot. Here is how brackets really work.
Federal brackets are layered
The US uses a progressive system. Your taxable income is split into slices, and each slice is taxed at its own rate. Only the income inside a bracket is taxed at that bracket's rate. These are the 2026 federal brackets for a single filer:
| Rate | Taxable income |
|---|---|
| 10% | $0 to $12,400 |
| 12% | $12,400 to $50,400 |
| 22% | $50,400 to $105,700 |
| 24% | $105,700 to $201,775 |
| 32% | $201,775 to $256,225 |
| 35% | $256,225 to $640,600 |
| 37% | $640,600 and above |

Marginal tax rate
Your marginal rate is the rate on your last (highest) dollar of taxable income. It tells you how much tax you would pay on a raise or bonus.
Effective tax rate
Your effective rate is your total tax divided by your income. It is always lower than your marginal rate, because your lower dollars are taxed at lower rates.
Worked example: $75,000 single filer
The standard deduction for a single filer in 2026 is $16,100, so taxable income is $58,900.
| Slice | Tax |
|---|---|
| First $12,400 at 10% | $1,240 |
| $12,400 to $50,400 at 12% | $4,560 |
| $50,400 to $58,900 at 22% | $1,870 |
| Total federal income tax | $7,670 |
The marginal rate is 22%, but the effective rate is only 13.0% of taxable income, or 10.2% of the full $75,000 salary.
Will a raise ever leave you with less?
No. If a raise moves part of your income into the next bracket, only the dollars above the line are taxed at the higher rate. Your total take-home pay still goes up.
