How 529 Plans Work
Open a plan in any state — you are not limited to your home state. Compare fees and investment options. Many plans offer age-based portfolios that auto-adjust risk.
Contribution limits are high ($300,000+ lifetime in most states). No annual federal limit, though gift tax rules apply above $18,000/year.
