What’s Your Effective Tax Rate?
Most people can rattle off their top federal tax bracket (their marginal rate), but don’t always know their effective tax rate.
Here is the difference.
Marginal Tax Rate:
●The rate on the last dollar of taxable income
●Tied to the highest bracket reached
Effective Tax Rate:
●Total federal income tax divided by total taxable income
●Always lower than the top bracket in a progressive system
Using simplified 2025 federal numbers for married filing jointly (Federal income taxes only, simplified illustrative figures only).
At $100,000 Taxable Income:
●Top federal bracket: 22 percent
●Effective federal rate: about 12 percent
At $250,000 Taxable Income:
●Top federal bracket: 24 percent
●Effective federal rate: about 18 percent
At $400,000 Taxable Income:
●Top federal bracket: 32 percent
●Effective federal rate: about 21 percent
Each layer of income is taxed at a different rate, so only the top slice hits the highest bracket.
Knowing both the marginal and effective rates can help keep tax conversations in perspective and make decisions more grounded. Your tax professional can provide additional insights.
