Most parents know they should open a 529. Almost no one does it the week their baby is born.
Here’s the math that changes that.
The Numbers
If you invest $95,000 at birth in a 529 (the 2026 superfunding limit per parent) at a historical average return of 6%:
By age 18: approximately $271,000.
That’s $176,000 in growth — tax-free, as long as it’s used for qualified education expenses.
Now here’s what happens if you wait until age 5:
Same $95,000. Same 6%. By age 18: approximately $190,000. You left $81,000 on the table by waiting five years.
What Is Superfunding?
The IRS allows a special election called “superfunding” — contributing up to 5 years of annual gift exclusions at once to a 529. In 2026:
- Annual gift exclusion: $19,000 per person
- 5-year superfunding limit: $95,000 per parent
- Per couple: $190,000 per child — in a single year, gift-tax free
The contribution counts as if it were made over 5 years. You file a gift tax return but owe no tax.
Which 529 Plan Should You Use?
You don’t have to use your home state’s plan — though many states offer a deduction for in-state contributions. Look for low-cost index funds. Vanguard, Fidelity, and Schwab all offer excellent options.
