Americans believe that there are two things that cannot be escaped in life: death and taxes. But death can be delayed by exercising. Tax payments may be reduced or deferred by law. The school will automatically withhold tax on the salary date. If you know that your personal annual tax status is below the minimum amount of tax you need to pay, you can notify the school not to deduct it, but you must declare it before April 15 next year. But social security must be paid.
