A 529 plan is a tax efficient savings plan that's designed to help save for college expenses. Money from a 529 plan can be used for college-related expenses like tuition, books, supplies, and fees. One tax benefit of a 529 plan is that states often allow income tax deductions for part or all of the contributions. Even better, the money grows tax-deferred and any distributions spent on college costs is exempt from taxes. In addition, contributions of a certain amount are considered gifts under federal tax laws. Any contributions of $13,000 ($65,000 over 5 years if filing single) or $26,000 ($130,000 over 5 years for those married filing jointly) count toward the gift exemption. Once you contribute the maximum amount, you are not able to make another contribution for another 5 years and have it count as a gift.
