How federal tax brackets work
The United States uses a progressive tax system, meaning your income is taxed at increasing rates as it moves through each bracket. Only the income within a given bracket is taxed at that bracket's rate - not your entire income. This is why your effective tax rate is always lower than your marginal rate.
For example, a single filer earning $50,000 in 2025 does not pay 22% on the full amount. The first $11,925 is taxed at 10%, the next portion up to $48,475 at 12%, and only the remaining income above that threshold at 22%. Your effective rate - the total tax divided by total income - ends up well below the top bracket you fall into.
Your filing status (single, married filing jointly, married filing separately, or head of household) determines the income thresholds for each bracket. Choosing the correct filing status is one of the most impactful decisions on your return. If you are unsure which status applies to your situation, a CPA can help you determine the most advantageous option.
