🎓 529 Qualified Tuition Plans: State Tax Deductions & Compounding College Wealth
A 529 College Savings Plan is a state-sponsored, tax-advantaged investment account established under Internal Revenue Code Section 529. Similar to a Roth IRA, contributions are made with post-tax dollars, investments grow completely exempt from federal and state capital gains taxes, and withdrawals for 'qualified higher education expenses' are 100% tax-free.
Over 30 US states offer state income tax deductions or tax credits for residents contributing to their home state's 529 plan. Furthermore, under the SECURE 2.0 Act, unused 529 funds can be rolled over directly into a Roth IRA for the beneficiary up to a lifetime limit of $35,000, eliminating fear of overfunding penalties.
