A 529 plan is a tax-advantaged investment account meant for education: money grows tax-free and comes out tax-free when spent on qualified expenses. For homeschoolers the rules are narrower than for college — whether 529 funds can go toward K–12 or homeschool costs depends on federal rules and your state's treatment, both of which have shifted in recent years. It's genuinely worth confirming the current law and your state's stance before counting on it. Where it does apply, it's a way to set aside education money with a tax benefit.
