The Hidden Power of 529 Plans: How Dentists Can Fund College with IRS Dollars

by PracticeCFO | October 7, 2025
A dentist wearing glasses and a mask stands confidently with crossed arms. In the background, a patient sits in a dental chair, creating a professional and caring atmosphere.

Dental practice owners are no strangers to high income—and equally high taxes. Many dentists work long hours to provide for their families, but too often, they allow the IRS to take more than its fair share. The result? Less money to put toward the things that matter most, like sending their kids to college debt-free.

Fortunately, the tax code has built-in strategies that allow dentists to reroute dollars away from the IRS and into their family’s future. One of the most powerful yet underutilized tools is the 529 education savings plan.

When combined with the payroll strategy of paying your children a reasonable wage, 529 plans can help you:

  • Reduce your taxable income
  • Build tax-free growth for future education expenses
  • Maintain control and flexibility over family assets

This blog will walk through exactly how dentists can unlock the hidden power of 529 plans—and how to use them alongside payroll dollars for maximum impact.

What Exactly Is a 529 Plan?

A 529 plan is a tax-advantaged savings account designed for education expenses. Each state offers its own version, but the rules are consistent across the country. Here’s what makes them special:

  • Tax-deferred growth: Investments inside the account grow without being taxed year-to-year.
  • Tax-free withdrawals: As long as the funds are used for qualified education expenses—like tuition, books, housing, and fees—withdrawals are tax-free.
  • Broad coverage: 529s are not limited to four-year universities. They can also be used for:
    • K–12 tuition
    • Vocational and trade schools
    • Apprenticeship programs
    • Up to $10,000 toward student loan repayment

This flexibility makes them one of the most versatile tax tools available for families.

Why 529 Plans Are Perfect for Dentists

Dentists often face unique financial challenges:

  • High income but limited deductions compared to other business owners
  • Student loan debt of their own, paired with the looming cost of their kids’ education
  • Pressure to balance lifestyle with savings often leads to overspending

A 529 plan addresses these issues head-on:

  1. You reduce your IRS bill by paying your children through payroll, then funneling those dollars into a 529.
  2. Your investment grows tax-free over the next 10–20 years.
  3. You retain control of the account as the parent.

Instead of writing another big check to the IRS, you transform that same money into a college fund.

Choosing the Right 529 Plan

Every state runs its own 529 program, but here’s the good news—you don’t have to pick your home state’s plan unless there’s a tax benefit.

Option 1: Your State’s Plan

  • If your state offers a state income tax deduction or credit for contributions, it often makes sense to stick with your state plan.
  • Example: Pennsylvania residents can deduct contributions to their 529 plan from state income taxes.

Option 2: Utah’s My529 Plan

  • If your state doesn’t offer a tax benefit, Utah’s My529 Plan is considered one of the best in the country.
  • Features:
    • Low-cost Vanguard index funds
    • Open to residents of all 50 states
    • High-quality investment options with minimal fees

Pro tip for dentists: Since you’re likely contributing larger amounts than the average family, the lower fees and better investment options of Utah’s plan can make a huge difference over 15–20 years of growth.

Why Parent Ownership Matters

One of the biggest mistakes families make is opening the 529 in the child’s name. While this seems intuitive, it can actually hurt more than help.

Here’s why dentists should keep ownership:

  • Better for financial aid: When a 529 is parent-owned, it has a smaller impact on financial aid eligibility compared to accounts in a child’s name.
  • More flexibility: If one child doesn’t need the funds, you can transfer them to siblings, cousins, or even hold them for future grandchildren.
  • Continued control: Parents decide how the money is invested and when it’s used.

By keeping the account in your own name, you ensure the funds stay flexible and under your guidance.

How to Fund a 529 Using Payroll

This is where the strategy really shines. By combining the kids-on-payroll approach with a 529 plan, you can effectively use IRS dollars to pay for college.

Here’s how it works step by step:

  1. Put your child on payroll for legitimate work in your dental practice.
    • Standard deduction in 2025: $15,750
    • Federal income tax owed by your child: $0
  2. Net after FICA tax: Around $14,000 left over.
  3. Split the contribution strategically:
    • $7,000 → Roth IRA (long-term retirement growth for your child)
    • $7,000 → 529 Plan (for education expenses)
  4. Result: You save on your own taxes while your child builds two powerful tax-free accounts.

This isn’t just a one-year benefit. Repeated over 10–15 years, the strategy can fund college tuition, reduce your tax liability, and set your children up for a lifetime of financial success.

Example: A Dentist with Three Children

Let’s run the numbers:

  • Each child earns $15,750 through payroll annually.
  • Net savings: ~$3,000–$4,000 per child in federal taxes each year.
  • Contributions: $7K into Roth + $7K into 529 per child.

Over 15 years, that dentist could:

  • Save $200,000+ in taxes.
  • Build $315,000+ in 529 savings (assuming conservative growth).
  • Create Roth accounts that could compound into millions by the time the children retire.

This is the power of combining payroll with 529 plans—it takes money the IRS would otherwise claim and gives it back to your family, where it belongs.

Common Questions About 529 Plans

Q: What if my child doesn’t go to college?
A: You can transfer the funds to another child, cousin, or even hold them for future grandchildren.

Q: What if we overfund the account?
A: Excess funds can now be rolled into a Roth IRA for the beneficiary (thanks to new rules), providing even more flexibility.

Q: Can I still access the funds if needed?
A: Yes, but withdrawals for non-qualified expenses are subject to taxes and penalties. That’s why it’s best to earmark the account for education.

Final Thoughts

As a dentist, you’re in a unique position to take advantage of this strategy. By paying your children through payroll and redirecting those dollars into a 529 plan, you:

  • Cut your own tax bill
  • Grow a college fund tax-free
  • Maintain control and flexibility
  • Provide your children with an education free of crushing student debt

This is the kind of proactive planning that separates dentists who just earn money from those who build lasting wealth for their families.
