Investopedia explains '529 Plan'
The prepayment may be in the form of a contribution to an account established specifically for paying higher educational expenses. There is no income restriction for individuals who want to contribute to a 529 plan; however, because contributions cannot exceed the amount that sufficiently covers the expenses of the beneficiary's qualified higher education, individuals should take care not to over-fund the 529 plan.
