The USA has payroll deduction, but the tax code is complicated enough that that's only a rough estimate of what you actually owe. What you actually owe cannot be determined and deducted ahead of time, because a person's true tax obligation depends on information and events that may not be available until up to ~105 days after the end of the tax year. So, every year, you have to do a bunch of paperwork (it took me over 4 hours this year) to calculate your actual tax obligation, and then either you send the government a check or they send you a check to settle the difference.
