Section 125 Plan for Dental Practices: 2026 Guide

A Section 125 plan lets a dental practice convert staff health premiums to pre-tax dollars, cutting employer FICA tax by 7.65% on every pre-tax dollar. For a 10-person practice, that often means $91 to $136 per employee per month in recaptured payroll tax.

Quick Answer (as of 2026): A Section 125 plan lets a dental practice run staff health insurance premiums through payroll before tax is calculated. The practice cuts its employer FICA tax by 7.65 percent on every pre-tax dollar, often $91 to $136 per employee per month. Staff take home $70 to $110 more each month.

A Section 125 plan for dental practices turns the premiums your team already pays into pre-tax payroll deductions, which lowers both the practice's payroll taxes and each employee's tax bill. A Section 125 plan, also called a cafeteria plan, is a written benefit plan under Section 125 of the Internal Revenue Code that lets employees pay for qualified benefits with money taken out before federal income tax and FICA are calculated. This guide shows the exact math for a small dental office, what it costs, and how to set one up.

What is a Section 125 plan for a dental practice?

A Section 125 plan for a dental practice is a written plan that lets dental staff pay for health insurance and other qualified benefits with pre-tax dollars. Every dollar an assistant or hygienist runs through the plan is removed from wages before income tax and FICA tax are calculated. The practice owner pays 7.65 percent less in employer FICA tax on each of those dollars, and the employee pays less federal income tax and FICA tax on the same dollars.

Dental practices are a strong fit because the staff mix is stable and the headcount is small enough to enroll in a single afternoon. A typical office has a dentist or two, a few hygienists, dental assistants, and one or two front-desk staff. Most of those employees already contribute toward a health plan with after-tax money, which means the tax savings are sitting there unclaimed. To see the underlying mechanics for any employer, read the Section 125 cafeteria plan 2026 guide.

How much does a dental practice save with a Section 125 plan?

A dental practice saves 7.65 percent in employer FICA tax on every dollar of staff premium that runs through the plan. For most practices that works out to $91 to $136 per enrolled employee per month in recaptured payroll tax, based on typical family and single premium contribution levels. The savings come from a reduced IRS Form 941 FICA deposit, not from operating cash, so the money is recovered at every payroll run.

Here is the math for a 10-person dental practice where each employee contributes about $1,400 per month toward health premiums:

  • Monthly pre-tax premium contributions: $14,000
  • Employer FICA recaptured at 7.65 percent: $1,071 per month
  • Annual employer FICA recapture: $12,852
  • Summit Health Benefits admin fee at $35 per employee per month: $4,200 per year
  • Net employer benefit after the fee: roughly $8,650 per year

Smaller premium contributions change the picture. The break-even point is about $457 per month in contributions per employee, which is $35 divided by 7.65 percent. Below that level, the practice still wins through lower employee income tax and stronger staff retention, but the headline FICA recapture is smaller. The deeper breakdown of the payroll tax side is in the maximizing FICA tax savings guide.

How much more do dental staff take home?

Dental staff take home $70 to $110 more per month with a Section 125 plan because their premiums come out before tax. Their net pay goes up, it never goes down, because the same premium is now paid with pre-tax dollars instead of after-tax dollars. The increase is real money in each paycheck on benefits the employee was already buying.

Consider a dental hygienist earning $85,000 who contributes $480 per month toward a family health plan. Running that $480 through a Section 125 plan removes it from federal income tax at the 22 percent bracket and from FICA at 7.65 percent. That is about $142 per month in combined tax savings, or roughly $1,700 more take-home pay per year on the exact same coverage. A front-desk coordinator at $42,000 contributing $300 per month sees a smaller but still meaningful monthly lift.

Which dental staff are eligible for a Section 125 plan?

W-2 employees of the dental practice are eligible for a Section 125 plan, including hygienists, dental assistants, front-desk staff, and office managers. The plan must pass annual nondiscrimination testing so it does not favor highly compensated employees or owners. Owner-dentists who are sole proprietors, partners, or more-than-2-percent S corporation shareholders cannot participate in the pre-tax benefit through the plan, though their W-2 staff can.

This owner rule trips up many practices structured as S corporations. The dentist who owns the practice does not get the pre-tax break on their own premiums, but every assistant, hygienist, and front-desk employee does. The savings case still works because the practice recaptures FICA on the whole eligible staff. For practices set up as S corporations, the S corp shareholder rules for Section 125 explain the specific limits.

What does a Section 125 plan cost a dental practice?

Summit Health Benefits administers a Section 125 plan for $35 per enrolled employee per month. The fee covers the written plan document, the summary plan description, annual nondiscrimination testing, and payroll setup support. For a 10-person practice, the annual fee is $4,200, and for most practices the recaptured FICA tax exceeds the fee several times over.

The fee is paid from the reduced FICA deposit, not from the practice's operating cash, so the plan funds itself at each payroll cycle once contributions clear the break-even point. There is no annual lump sum and no setup charge beyond the monthly per-employee rate.

Frequently Asked Questions

Can a small dental practice with under 10 employees use a Section 125 plan?
Yes. A Section 125 plan has no minimum employee count, so a dental practice with 3 or 4 staff can use one. The plan still cuts employer FICA tax by 7.65 percent on every pre-tax premium dollar and raises staff take-home pay. Smaller practices often see the fastest setup because enrollment takes a single short meeting.
Does the dentist who owns the practice get the pre-tax savings too?
It depends on how the practice is structured. A more-than-2-percent S corporation shareholder, a partner, or a sole proprietor cannot take the pre-tax benefit on their own premiums through a Section 125 plan. The practice's W-2 employees, including hygienists and assistants, are fully eligible, and the practice still recaptures FICA tax on their contributions.
How much does a Section 125 plan cost a dental practice?
Summit Health Benefits charges $35 per enrolled employee per month. The fee covers the plan document, summary plan description, annual nondiscrimination testing, and payroll setup. For most dental practices, the recaptured employer FICA tax is several times larger than the fee, and the fee is paid from the reduced FICA deposit rather than operating cash.
What benefits can dental staff pay for pre-tax under a Section 125 plan?
Dental staff can pay for health insurance premiums, dental and vision premiums, health flexible spending accounts, and dependent care assistance with pre-tax dollars under a Section 125 plan. The qualified benefits are defined by Section 125 of the Internal Revenue Code. Each pre-tax dollar lowers both the employee's income and FICA tax and the practice's employer FICA tax.
Will a Section 125 plan lower my dental staff's paychecks?
No. A Section 125 plan raises staff take-home pay because their premiums come out before tax instead of after tax. Net pay goes up by $70 to $110 per month for typical dental staff on the same coverage they already had. The plan does not change the benefit itself, only the tax treatment of the premium.
How long does it take to set up a Section 125 plan for a dental office?
A dental office can have a Section 125 plan running in a few weeks. Summit Health Benefits drafts the plan documents, runs a short staff enrollment meeting, and configures the payroll deduction codes. Once the codes are live, the FICA savings appear on the very first pre-tax payroll for both the practice and the staff.
Does a Section 125 plan require nondiscrimination testing?
Yes. Section 125 of the Internal Revenue Code requires annual nondiscrimination testing so the plan does not favor highly compensated employees or owners over rank-and-file staff. Summit Health Benefits runs this testing as part of the $35 per employee per month service. For most dental practices with a typical staff mix, the plan passes without changes.
Is a Section 125 plan the same as offering group health insurance?
No. A Section 125 plan is the tax wrapper that lets employees pay premiums pre-tax, not the insurance itself. A dental practice can pair a Section 125 plan with a group health plan or with other coverage options. If your practice is weighing coverage choices, the small business health insurance alternatives guide covers the main routes.
