529 college savings plans are popular tax-advantaged options for funding higher education. They offer tax-free growth and withdrawals for qualified expenses, making them attractive for parents saving for their children's future. However, their benefits and limitations vary by state and plan, so it's crucial to research and compare options before investing. Additionally, 529s aren't the only way to save for college, and other options like prepaid tuition plans or Roth IRAs may be better suited for some families.
