How much can you contribute to a 529 plan?

There's no annual federal limit. However, contributions above $18,000/year ($36,000 for married couples) count against the federal gift tax exclusion. Total account limits range from $235,000 to $550,000+ by state. You can superfund 5 years at once ($90,000) without gift tax implications.

What are the tax benefits of a 529 plan?

Earnings grow tax-free federally, and withdrawals for qualified education expenses are tax-free. Over 30 states offer a state tax deduction or credit for contributions, saving $200-$1,000+ per year depending on your state.

What if my child doesn't go to college?

You can change the beneficiary to another family member (sibling, cousin, yourself), use funds for trade school or K-12 tuition (up to $10,000/year), or starting in 2024, roll up to $35,000 into a Roth IRA. Non-qualified withdrawals face income tax plus a 10% penalty on earnings only.
