Progressive Federal & FICA Tax Guide
累進課税の仕組みと限界税率・実効税率の違い
要約: 高い税率区分に入っても、その高い税率が適用されるのは「基準額を超えた超過部分のみ」です。全額に対して高税率がかかるわけではありません。
The United States tax system operates on a progressive tier structure. Higher portions of your taxable income are taxed at higher marginal rates, ensuring your effective overall tax rate is significantly lower than your top marginal bracket.
