Do you get taxed if you only work 16 hours per week?

Answer 1

It depends on which tax you are talking about. There may be city income taxes, state income taxes, and federal income taxes, plus a tax for Medicare and a tax for Social Security. The Medicare and Social Security taxes are always taken from any amount of income.

City, State and Federal income taxes have different rules. You have to look up those rules. For instance, some full time students don't have to pay federal income tax. Most tax rules have rules about how much you can earn before you get taxed.
