A 529 plan is the most tax-efficient way to save for education. Earnings grow tax-free, withdrawals for school are tax-free, and most states give you a tax deduction for contributing.
Unlike regular taxable brokerage accounts, 529 plans offer triple tax benefits: contributions may reduce your state taxes, growth is tax-deferred, and qualified withdrawals are completely tax-free. Combined with the new Roth IRA rollover option, 529s have become even more flexible. See our compound interest calculator to project your growth.
Quick answer: A 529 plan offers tax-free growth and tax-free withdrawals for qualified education expenses. Contribute up to $18,000/year without gift tax implications. $200/month from birth grows to $86,000+ by age 18 (at 7% return).

The Bottom Line
A 529 plan is the best way to save for education expenses if you start early. Contributing $200/month from birth can grow to over $86,000 by age 18 with tax-free growth. If your state offers a tax deduction, you get an immediate tax benefit too. Even if your child doesn’t attend college, the funds can be used for trade school, transferred to another family member, or rolled into a Roth IRA.
For families also saving for retirement, balance 529 contributions with 401(k) and IRA contributions—retirement savings typically take priority since you can borrow for school but not for retirement.
