A 529 plan is a tax-advantaged savings account for education expenses. Contributions grow tax-free, and withdrawals for qualified education expenses (tuition, room and board, books) are also tax-free. Many states offer a state income tax deduction for contributions.
Education inflation. College costs have historically risen at 4–6% per year, faster than general inflation. A school costing $35,000/year today could cost $57,000–$62,000/year in 13 years. Ignoring this understates your savings need.
529 investment options. Most plans offer age-based portfolios that automatically shift from stocks to bonds as college approaches, and individual fund options. Early contributions benefit from decades of growth — starting early matters enormously.
Qualified expenses. Tuition, fees, required books, supplies, room and board (up to the school's cost of attendance), and technology required for enrollment. Non-qualified withdrawals face income tax plus a 10% penalty on earnings.
Contribution limits. There are no annual contribution limits, but contributions above the annual gift tax exclusion ($18,000 per donor in 2025 — VERIFY) may trigger gift tax reporting. You can superfund a 529 by contributing up to 5 years of exclusions at once ($90,000).
