Back Door Roth for Kids

College planning is one of the trickiest areas of financial planning. Parents naturally want to give their kids a leg up in life, but not everyone feels like they can contribute a “meaningful” amount, and even those who can often wonder if it’s the right decision.

College itself is no longer the default path for every child. While 529 college savings accounts are more flexible than people realize, there is a real risk of “locking up” money in a system that may not be used if your kids don’t go to college.

We often remind clients, “college is optional; retirement isn’t.” Usually, we’re reminding them to balance their priorities when planning for their retirement and their children’s college, but the same will hold true for your children. College may be optional on their path to success, but at some point, they will need to plan for retirement.

If you want to give your kids a head start in life, why not put them ahead on the one challenge you know they’ll face?

Why Roth IRAs Are So Powerful

When it comes to retirement, it’s hard to beat a Roth IRA. They allow for tax-free growth during a person’s working years and tax-free withdrawals in retirement. Unlike traditional IRAs, they don’t carry required minimum distributions, which means money can remain invested and compounding for as long as the account holder wishes. Roths also offer flexibility: in addition to retirement savings, funds can be accessed penalty-free for a first-time home purchase, education costs, or emergencies.

They are especially powerful for young people. Beginning early means decades of tax-free compounding, which is the closest thing to a financial superpower that ordinary investors can access. The one catch is that Roth contributions require earned income. Parents cannot simply open and fund a Roth IRA for a child unless that child has a job, which delays the opportunity to take full advantage of compounding.

Using a 529 as a Back Door to the Roth

Recent changes to the rules around 529 accounts created a new opportunity: unused 529 balances can be rolled into a Roth IRA for the beneficiary, subject to certain rules. While intended to lessen the pain of overfunding a college savings plan, in effect they mean you can use a 529 not just to fund college, but to seed your child’s retirement account and provide them with tax-free growth for life.

Keep in mind:

• There are some restrictions surrounding the length the account has been open and when contributions were made, so the strategy works best when your kids are young.
• If you take advantage of a state tax deduction on your 529 contribution, you may face claw back provisions from the state if the funds are not ultimately used for education purposes. If you do live in a state with such provisions, you can always use another state’s 529 plan.
• The biggest restriction is that the amount that can be converted to a Roth IRA is capped at $35,000, but even a modest contribution could give your kids a major leg up in life.

A Case Study

Imagine parents contribute $5,000 to a 529 plan when their child is born. Assuming a 7% annual growth rate, by age 18 the account would grow to about $16,900.

At that point, if the child has earned income, up to $7,000 per year can be rolled into their Roth IRA. Within three years, the entire balance is transferred. Left untouched, that Roth could grow for 40+ years. By retirement age, the account could be worth over $280,000 tax-free—all from one modest contribution at birth.

More Than Money

This strategy isn’t just about the dollars though. It’s also a way to teach your kids about the power of compounding and the value of long-term planning. Watching a small seed grow into a meaningful sum shows them—tangibly—how patience, consistency, and smart investing pay off.

For parents who want to give their kids a leg up, this can be one of the most powerful gifts: not just money for college, but the foundation of a financially secure future.
