US: 529 college savings plans

A 529 plan is a US tax-advantaged account for education costs — college, and within limits, K–12 and apprenticeships.

How it works

• You contribute after-tax money; investments (usually age-based fund portfolios) grow tax-free.
• Withdrawals are tax-free when used for qualified education expenses (tuition, fees, books, room and board within limits).
• Many states offer a tax deduction or credit for contributions to their plan.

Key features

• High contribution ceilings and no annual federal limit (though large gifts interact with gift-tax rules).
• You keep control as the account owner, even though the child is the beneficiary.
• Beneficiary flexibility: unused funds can often be moved to another family member, and — subject to rules — some leftover amounts may be rolled to a Roth IRA for the beneficiary.

Things to weigh

• Non-qualified withdrawals of earnings face income tax plus a penalty.
• Investment options are set by the plan; compare fees and consider your own state's tax break first.

Key takeaway

For families saving for education, a 529 offers tax-free growth and withdrawals, plus possible state tax breaks — a powerful, purpose-built tool. Start early so compounding can work, and check your state's plan and current rules.
