Marginal vs Effective Tax Rate

Your marginal tax rate is the rate on your last dollar of income — the bracket you're 'in.' Your effective rate is total tax divided by total income, and it's always lower because your earlier dollars were taxed in lower brackets. Being in the 22% bracket does not mean you pay 22% on everything.

The distinction matters for decisions: a deduction saves you tax at your marginal rate, while your effective rate tells you the real share of income you actually pay. In 2026 a single filer in the 22% bracket typically has an effective federal rate well under 15%.
