529 Education Savings Plan

A 529 plan is a tax-advantaged savings account designed for education expenses. Contributions grow tax-free and withdrawals for qualified education costs (tuition, room & board, books) are also tax-free. Most states offer a deduction or credit for contributions.

Formula
Tax-free growth: same as compound interest, applied to education savings
Example

Saving $300/month from birth through age 17 at 7% annual return → ~$114,000 tax-free for college.

529 plans are sponsored by states but usable at any qualifying school nationwide (and many abroad). The two types are savings plans (invest in mutual funds; balance varies with market) and prepaid tuition plans (lock in today's tuition rates at in-state schools).

There is no federal deduction for 529 contributions, but over 30 states offer a state income tax deduction or credit, often worth $500–$2,000 per year. Some states require you to use their own plan; others allow any plan.

Starting 2024, unused 529 funds can be rolled over to a Roth IRA for the beneficiary (up to $35,000 lifetime, subject to annual Roth limits), providing an exit route if the beneficiary doesn't use the money for education.
