“In the interest of encouraging workers to save for retirement, Congress has authorized several kinds of retirement savings plans that qualify for reduced or deferred income taxes. These plans provide a financial incentive for people to save, either by allowing workers and employers to deduct from income the amount they contribute to the plan or to take tax-free distributions from the plan after they retire. This CRS Report summarizes the provisions of law that govern the taxes applicable to pre-retirement distributions from retirement accounts, and the situations in which distributions must be taken from a plan in order to avoid a tax penalty.”
