The Tax Drag Elimination Advantage
In a standard taxable brokerage account, you are taxed every single year on mutual fund dividends and internal capital gains distributions (losing 1.5% to 2.5% in drag). Over 18 years, a 529 plan generates over $25,000 more in net spendable college wealth on the exact same underlying index fund investments.
Frequently Asked Questions (529 College Plans)
How does a 529 plan affect FAFSA financial aid eligibility?
A 529 account owned by a parent is treated as a Parental Asset on the FAFSA, which reduces aid eligibility by at most 5.64% of the asset value (compared to 20% for assets held directly in the student's name like UGMA/UTMA accounts). Furthermore, under the simplified FAFSA, distributions from grandparent-owned 529s no longer count as student untaxed income!
Can 529 funds be used for non-college education?
Yes! 529 funds can be used tax-free for up to $10,000/year per student for K-12 private school tuition, registered apprenticeship programs, trade and vocational schools, and up to a $10,000 lifetime limit to pay off qualified student loans.
