529 plans are savings plans designed specifically for educational expenses. When the money earned in a 529 plan is used to pay for a qualifying expense such as college tuition, it can be withdrawn tax-free. Anyone can open a 529 account, but parents often set them up for their children to use in the future. You’ll put after-tax dollars in a 529 plan, so you won’t pay any additional taxes when you withdraw funds to use for education.
