Your effective tax rate is your total tax paid divided by your total income. It represents the actual percentage of income you pay in taxes. Due to progressive tax brackets, it's always lower than your marginal rate.
Your marginal tax rate is the rate you pay on your last dollar of income. It's the tax bracket you're in. This rate applies only to income above certain thresholds, not your entire income.
Deductions reduce your taxable income (save tax × marginal rate). Credits reduce your tax dollar-for-dollar. A $1,000 credit saves $1,000; a $1,000 deduction saves $220-$370 depending on your bracket.
Understanding your effective rate helps with financial planning. If you're in the 22% bracket but your effective rate is 12%, you're not losing 22 cents of every dollar—you're keeping 88 cents.
The marginal tax rate is the rate applied to your last dollar of taxable income -- your highest bracket. The effective tax rate is your total federal tax divided by total income, representing the actual percentage you pay. Due to progressive taxation, these two numbers are always different.
Consider a single filer with $100,000 in taxable income for 2026. Their marginal rate is 22% (the bracket covering $48,475 - $103,350). But their tax is computed across all brackets:
| Bracket | Rate | Income Taxed | Tax |
|---|---|---|---|
| $0 - $11,925 | 10% | $11,925 | $1,193 |
| $11,925 - $48,475 | 12% | $36,550 | $4,386 |
| $48,475 - $100,000 | 22% | $51,525 | $11,336 |
| Total | $16,915 | ||
Effective rate: $16,915 / $100,000 = 16.9% -- nearly 5 points below the 22% marginal rate. This distinction matters for financial planning: earning an additional $1,000 costs $220 in tax (marginal), but your overall rate remains around 17%.
Your true effective rate includes more than just federal income tax. For a W-2 employee, total federal taxes include:
For a single filer earning $100,000: federal income tax is roughly $16,915, Social Security is $6,200, and Medicare is $1,450, totaling $24,565 or an effective rate of 24.6% when including FICA. Self-employed workers pay both halves of FICA through the 15.3% self-employment tax on 92.35% of net income, resulting in even higher combined effective rates.
Adding state income tax pushes rates higher still. A California resident in the 9.3% state bracket has a combined effective rate approaching 34% on the same $100,000 income. In contrast, a Texas or Florida resident with no state income tax pays only the 24.6% federal + FICA rate.
IRS Statistics of Income data shows that effective federal income tax rates (excluding FICA) vary significantly by income level. Approximate averages for single filers using 2026 brackets:
| Taxable Income | Marginal Bracket | Approximate Effective Rate |
|---|---|---|
| $25,000 | 12% | 10.6% |
| $50,000 | 22% | 13.0% |
| $100,000 | 22% | 16.9% |
| $200,000 | 32% | 21.2% |
| $500,000 | 35% | 28.5% |
| $1,000,000 | 37% | 32.2% |
These rates assume the standard deduction of $15,700 (single) for 2026 and no additional credits. Actual effective rates are often lower because of above-the-line deductions (IRA, HSA, student loan interest), tax credits (child tax credit, education credits), and preferential rates on qualified dividends and long-term capital gains.
The gap between marginal and effective rates grows wider at higher income levels. A taxpayer in the 37% bracket typically pays an effective rate of 30-33% because a large portion of their income is taxed at the lower brackets first.
