❓ Effective Tax Rate Calculator FAQ
What is the difference between effective and marginal tax rate?
Marginal tax rate is the rate you pay on your last dollar of income (your highest tax bracket). Effective tax rate is the average rate you pay across all your income (total tax ÷ gross income). Your effective rate is always lower than your marginal rate.
What are the 2026 federal income tax brackets?
The 2026 tax rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For single filers: 10% up to $12,400; 12% up to $50,400; 22% up to $105,700; 24% up to $201,775; 32% up to $256,225; 35% up to $640,600; 37% over $640,600.
What is the 2026 standard deduction?
The 2026 standard deduction is $16,100 for single filers and married filing separately, $32,200 for married filing jointly, and $24,150 for head of household.
Why is my effective tax rate lower than my marginal rate?
Because the US has a progressive tax system. Only the portion of your income that falls into each bracket is taxed at that rate. The first $12,400 is taxed at 10%, the next portion at 12%, and so on. Your effective rate is a weighted average of all these rates.
How do I choose my filing status?
Your filing status depends on your marital status and household situation: Single if unmarried, Married Filing Jointly if married and filing together, Head of Household if unmarried and paying more than half the cost of keeping up a home for a qualifying person, or Married Filing Separately if married but filing separate returns.
