About Tax Calculators

US tax math is bracket-based and easy to get wrong by hand - these calculators apply current federal brackets, self-employment and payroll rates, and capital gains rules the way the IRS actually applies them, including the difference between your marginal rate and your effective rate. They're built for realistic estimates before you file or make a decision, not as a replacement for a tax professional on anything unusual.
