Frequently asked questions
Is this my exact tax bill?
No. This is a simplified federal estimate using standard brackets — it excludes deductions, credits, state tax, and payroll tax. Treat it as a planning estimate.
What is the difference between effective and marginal rate?
Marginal rate is the bracket your last dollar falls in; effective rate is total tax divided by total income. Effective is always lower than marginal.
