College tuition has increased faster than inflation for 40 consecutive years. By the time your toddler turns 18, four years at an in-state public university could easily run $150,000–$200,000. At a private school, $300,000+.
The 529 plan is the most tax-efficient vehicle available to prepare for that. It takes 20 minutes to open, requires no ongoing management, and the tax benefits are significant enough that not using one is leaving real money on the table.
What a 529 Actually Is
A 529 is a tax-advantaged investment account specifically for education expenses. You contribute after-tax dollars — no tax break on the way in at the federal level — but all growth and qualified withdrawals are completely tax-free. For accounts that compound for 18 years, that’s a meaningful advantage.
Qualified expenses include tuition, fees, room and board, books, and (since 2019) up to $10,000/year toward K–12 private school tuition. Recent legislation also allows rolling unused funds into a Roth IRA under certain conditions.
Which 529 Plan to Choose
Every state has its own 529 plan, but you’re not restricted to your home state’s plan. You can open any state’s plan for any school in the country.
The criteria for choosing: investment options and expense ratios. A plan with low-cost index fund options (Vanguard, Fidelity, or Schwab index funds at 0.03–0.15% expense ratios) beats your home state’s plan with 1% expense ratios even if your state offers a modest income tax deduction on contributions.
Top consistently-rated plans: Utah Educational Savings Plan (my529), Nevada’s Vanguard 529, New York’s 529 Direct Plan, and Fidelity’s New Hampshire plan. All offer excellent low-cost index fund options.
If your state offers a meaningful income tax deduction for contributions (California, New York, Virginia, and others do), check whether the tax savings outweigh the expense ratio difference before defaulting to an out-of-state plan.
How Much to Contribute
The simple approach: aim to cover roughly 50% of projected college costs with savings, planning to use income at college time for the rest.
A rough target: $300–$500/month started at birth grows to approximately $100,000–$160,000 by age 18 at historical stock market returns. That covers a significant portion of in-state tuition at most universities.
If $300/month isn’t realistic now, $50/month is better than zero. The accounts also accept contributions from grandparents, which many families use for birthday and holiday gifts in lieu of toys.
Setting One Up This Week
The process: choose a plan, create an account on their website (10 minutes), name your beneficiary (the child), choose an investment option (target-date fund set to the child’s expected college start year is the simplest choice), and set up automatic monthly contributions.
Vanguard, Fidelity, and your state’s plan website all walk you through this. You’ll need the child’s Social Security number, which you should have from their birth certificate and Social Security card.
The One Mistake to Avoid
Over-saving at the expense of your own retirement. The 529 is important, but it competes with your 401(k) and Roth IRA contributions. Financial aid exists for college. Retirement welfare does not. If you have to choose, prioritise your retirement savings first, then fund the 529 with what remains.
Your action step: this weekend, choose a plan, open an account, and set up even a small automatic monthly contribution. Starting is what matters — you can increase the amount later.
