Marginal vs Effective Tax Rate
Marginal Tax Rate is the rate you pay on your next dollar of income. The U.S. uses a progressive tax system, meaning different portions of your income are taxed at different rates.
Effective Tax Rate is your total tax divided by your total income. This represents your actual average tax rate across all your income.
For example, if you're single with $50,000 taxable income:
- First $11,600 taxed at 10% = $1,160
- Remaining $38,400 taxed at 12% = $4,608
- Total tax = $5,768
- Marginal rate = 12%
- Effective rate = 11.5% ($5,768 ÷ $50,000)
How Tax Brackets Work
Tax brackets are marginal, meaning only the income within each bracket is taxed at that rate. Going up a tax bracket never means all your income is taxed at the higher rate—only the amount above the bracket threshold.
Frequently Asked Questions
Only the portion of your income above the bracket threshold is taxed at the higher rate. A raise never reduces your take-home pay. For example, moving from $45,000 to $50,000 only subjects the extra $5,000 to a potentially higher rate, not your entire income.
Tax deductions reduce your taxable income (saving you money at your marginal rate). Tax credits directly reduce your tax bill dollar-for-dollar. A $1,000 credit saves you $1,000, while a $1,000 deduction might save you $120-$370 depending on your bracket.
Tax brackets are typically adjusted annually for inflation. Congress can also change tax rates and brackets through legislation. The brackets shown are for the 2024 tax year (returns filed in 2025).
