Common Mistakes to Avoid

⚠️
Starting too late

Starting 529 savings at birth vs age 10 can result in 2-3x more money at enrollment due to compound growth over the full 18 years.

⚠️
Forgetting state tax deductions

Most states offer tax deductions for in-state 529 contributions. This provides an immediate 3-10% return on contributions. Always invest in your state's plan first (unless it has very high fees).

⚠️
529 affects financial aid

529 savings (up to 5.64% assessed) affect FAFSA-based aid less than other savings. Parent-owned 529s are most favorable; grandparent-owned 529s now have no impact on aid under new FAFSA rules.
