It can vary. The effective federal income tax rate is around fifteen to twenty percent for most earners. There’s another 7.5 percent or so for federal benefits (Medicare and Social Security). State income taxes vary from zero in a few states to thirteen percent on the highest income bracket in California, but probably average out to five or six percent. Most (or all?) states require employees to cover some burden of their unemployment insurance as well. Some municipalities also have income taxes.
Americans also usually pay taxes on their homes, cars, and sales tax.
