Income tax estimator: brackets and quick checks

Marginal vs. effective rate

Income tax is usually progressive: higher slices of income can face higher marginal rates. Your effective rate is typically lower than the top marginal rate because lower brackets still apply first.

Why estimate?

Planning withholdings, side-income, or year-end moves is easier when you understand approximate liability. Always confirm with a CPA or official software for filing.
