Income Tax Calculator

Calculate income tax owed by applying a flat tax rate to total income β€” a simplified shortcut for estimating tax burden in flat-rate jurisdictions or for back-of-envelope marginal-rate math. Use it for quick gut-checks; for real US federal tax which uses progressive brackets, use a dedicated tax-bracket calculator instead.
