Section 125 Plan for Physical Therapy Clinics: The 2026 Employer Guide

• Physical therapist aides earned a median $35,240 per year and physical therapist assistants a median $68,380 per year in May 2025, according to the Bureau of Labor Statistics Occupational Outlook Handbook.
• Offices of physical, occupational and speech therapists, and audiologists employ 44% of the 114,100 physical therapist assistant jobs and 65% of the 49,000 physical therapist aide jobs, per the Bureau of Labor Statistics (2025 employment).
• CMS proposed a 1.68% cut to the Medicare conversion factor for 2027 in its July 16, 2026 proposed rule, though APTA reports CMS estimates a 1% to 3% overall increase for physical therapy codes after practice expense changes.
• Sole proprietors, partners, and more-than-2% S corporation shareholders cannot make pre-tax Section 125 elections, which affects many owner-therapists.
• A 400-employee multi-state platform (a disclosed hypothetical) saves approximately $55,080 per year in employer FICA at typical election levels.

A physical therapist aide in suburban Chicago who earns the national median of $35,240 a year keeps an extra $31.98 a month the day her clinic turns on a Section 125 plan, for coverage she was already paying for after tax. Her clinic owner, meanwhile, is watching Medicare's 2027 proposed rule trim the conversion factor again while wages for aides and assistants keep rising. Payroll tax is one of the few clinic costs an owner can reduce without touching visit volume, staffing ratios, or patient care, and most independent physical therapy clinics have never set it up. The full benefit stack every Benecor plan participant receives is in the table below.

How much does a Section 125 plan save a physical therapist aide?

A Section 125 plan saves a physical therapist aide earning $35,240 a year about $31.98 per month in take-home pay on a $130 monthly benefit election in Illinois, and it saves the clinic $119.34 per year in employer FICA on that same employee. A Section 125 plan, also called a cafeteria plan, is an IRS-approved arrangement under Internal Revenue Code Section 125 that lets employees pay for qualified benefits before federal income tax, most state income tax, and FICA are taken out. FICA is the combined Social Security (6.2%) and Medicare (1.45%) payroll tax, and the employer pays a matching 7.65% on the same wages. The aide in this example works at an outpatient orthopedic clinic in Naperville, Illinois, and earns the May 2025 Bureau of Labor Statistics median for physical therapist aides. Illinois taxes wages at a flat 4.95%, so her paycheck runs three tax layers: federal income tax, Illinois income tax, and FICA. Moving her $130 monthly election from after-tax to pre-tax lowers all three.

The aide keeps $14.76 more every two weeks, or $31.98 a month, for the same coverage. The clinic recaptures $130 x 12 x 7.65% = $119.34 per year in employer FICA. That figure depends only on the election amount, not on the employee's wage, so a front-desk coordinator, an aide, and a physical therapist electing the same $130 generate the same employer savings. Higher earners save more on the employee side because their federal bracket is higher. A physical therapist assistant earning the $68,380 May 2025 median, for example, is likely in the 22% federal bracket, which raises the per-dollar tax savings on each pre-tax election. See the full Illinois Section 125 guide→ for state-specific rules.

Why does payroll tax matter more when Medicare rates stay flat?

Payroll tax matters more for physical therapy clinics than for many small businesses because a large share of clinic revenue is set by payer fee schedules the owner cannot negotiate, while wages keep rising. An outpatient clinic that bills Medicare Part B is paid under the Medicare Physician Fee Schedule, which multiplies each code's relative value units by a national conversion factor that the Centers for Medicare and Medicaid Services (CMS) updates every year. Commercial payers often benchmark their own rates to Medicare. When the conversion factor falls or barely moves, a clinic cannot raise prices to cover higher labor costs. It has to find savings elsewhere. Employer FICA is a fixed 7.65% of wages that most clinics pay on every dollar of benefit premiums their staff contribute, and a Section 125 plan removes that tax on the pre-tax portion. That makes it one of the few cost levers that does not reduce visit capacity, cut staff hours, or change how care is delivered.

The 2027 Medicare fee schedule proposal for physical therapy

CMS published its CY 2027 Medicare Physician Fee Schedule Proposed Rule on July 16, 2026, with comments due September 14, 2026. The proposal sets the conversion factor for most clinicians, including physical therapists, at about $32.84, a 1.68% decrease from the 2026 figure of about $33.40, largely because a temporary 2.5% increase Congress attached to 2026 payments expires. The American Physical Therapy Association (APTA) reports that CMS still estimates physical therapy codes could see an overall payment increase of 1% to 3%, because proposed changes to how practice expenses are calculated favor clinicians outside advanced alternative payment models. The final rule usually arrives in early November. Whatever the final number, the pattern for independent clinics has been years of small or negative updates against steadily higher wages for aides and assistants.

Can a physical therapy clinic owner join the clinic's Section 125 plan?

A physical therapy clinic owner can join the clinic's Section 125 plan only if the owner is a W-2 employee of a C corporation or holds 2% or less of an S corporation. Many independent clinics are owned by the physical therapist who treats patients there, and how that owner set up the business decides whether the owner's own premiums can go through payroll pre-tax. Under IRS rules, a sole proprietor is self-employed, not an employee. Partners in a partnership or multi-member LLC taxed as a partnership are also self-employed. A shareholder who owns more than 2% of an S corporation is treated like a partner for fringe benefit purposes under IRC Section 1372, so that owner cannot make pre-tax Section 125 elections either. None of this blocks the plan for everyone else. Every W-2 physical therapist, PTA, aide, and front-desk employee can still participate, and the clinic still recaptures employer FICA on every one of their elections. Review the full Section 125 eligibility and compliance flow→ in the pillar guide.

Section 125 owner rules by entity type

Owner-therapists in the first three structures often still deduct their own health insurance through the self-employed health insurance deduction on their personal return. That deduction is separate from Section 125 and should be confirmed with the clinic's CPA.

How do PRN and part-time physical therapists fit into a Section 125 plan?

PRN and part-time physical therapists fit into a Section 125 plan through the eligibility rule the clinic writes into its plan document, because Section 125 itself sets no minimum hours. PRN means "as needed": a therapist who covers vacations, evening slots, or a Saturday clinic without a fixed schedule. Many outpatient clinics rely on PRN therapists and part-time assistants to cover early-morning and after-work appointment blocks, when patients who work day jobs want to come in. A clinic can make every W-2 employee eligible, set an hours threshold such as 20 or 30 hours per week, or exclude employees under a set tenure. The choice matters for two reasons. First, a wider eligible group means more elections and more FICA recaptured. Second, a narrow group that leaves out lower-paid part-time aides while covering salaried therapists and the owner can make the plan harder to pass on nondiscrimination testing. One firm rule applies either way: PRN clinicians paid on a 1099 as independent contractors are not employees and cannot participate. See how eligibility design affects nondiscrimination testing→ before setting the threshold.

What physical therapy clinic staff actually get

Physical therapy staff spend their days on their feet, lifting, guarding, and transferring patients, and an aide who strains a back on a Tuesday rarely wants to give up a paid shift to see a doctor. Benecor plan participants get care that fits around a clinic schedule built on 45- and 60-minute visits. See how the same benefit stack works across every industry on the Section 125 hub→.

• $0 Virtual Urgent Care, 24/7: An aide who tweaks a shoulder during a transfer can reach a licensed clinician that evening without missing the next day's schedule.
• $0 Virtual Primary Care: Routine visits and prescription renewals without blocking out patient slots.
• $0 Mental Health Counseling: Support for a workforce that carries heavy caseloads and documentation demands.
• 800+ commonly prescribed medications at $0, fully covered: Maintenance medications with no out-of-pocket cost from the first payroll cycle.
• Procedures at 57% savings, specialist visits at 35% off, lab tests at 60% off, imaging at 75% off: Lower out-of-pocket costs when in-person care is needed.
• Dental, vision, and family coverage with 350,000+ doctors nationwide: Coverage that follows a PRN therapist who works across several clinic locations.

What does a Section 125 plan save a physical therapy clinic, from one location to a multi-site group?

A Section 125 plan saves a physical therapy clinic about $119 to $138 per enrolled employee per year in employer FICA at typical election levels of $130 to $150 per month, so total savings scale directly with headcount and enrollment. The figures below assume every eligible employee enrolls at the average election shown. Actual savings depend on how many employees enroll and how much each elects, which is why Benecor models a clinic's real roster before anything is signed. The physical therapy industry spans single-owner clinics, regional groups with a handful to a few dozen locations, and large platforms. U.S. Physical Therapy, a publicly traded operator, reported owning or managing 780 clinics in 44 states as of December 31, 2025, in its Form 10-K. According to U.S. Census Bureau business data for 2020, the broader industry that includes physical therapy offices (NAICS 621340) had 30,434 firms, 47,101 locations, and 431,257 workers, which shows how many operators are small, independently owned practices.

Single-location clinics

A 12-employee single clinic, typically an owner-therapist, three or four staff physical therapists, a PTA, several aides, and a front-desk coordinator, generates approximately $1,432 per year in employer FICA recapture at a $130 average monthly election. If the owner operates as an S corporation with more than 2% ownership, the owner does not participate personally, but all 11 other W-2 employees can.

Regional multi-clinic groups

A 60-employee regional group running five or six clinics across a metro area generates approximately $7,711 per year in employer FICA recapture at a $140 average monthly election. At this size the plan should apply one eligibility rule across every location, so a PRN therapist who floats between clinics is treated the same no matter where she is scheduled.

Private-equity-backed and multi-state platforms

A disclosed hypothetical 400-employee multi-state platform generates approximately $55,080 per year in employer FICA recapture at a $150 average monthly election. This figure is a hypothetical scenario, not a claim about any named company's headcount or plan design. Platforms at this size often grow by acquiring independent clinics, and each acquisition brings its own payroll setup and benefit history, so bringing acquired clinics onto one Section 125 plan document is a common integration step.

What compliance rules matter most for physical therapy clinic owners?

The compliance rules that matter most for physical therapy clinic owners are the three annual Section 125 nondiscrimination tests, because physical therapy clinics often pair a small number of well-paid owner-therapists with a larger group of hourly aides and assistants. The Eligibility Test checks that the plan is open to a fair cross-section of employees, not just the higher paid. The Contributions and Benefits Test checks that highly compensated participants do not elect or receive a disproportionate share of benefits. The Key Employee Concentration Test caps the nontaxable benefits flowing to key employees at 25% of the plan total. A clinic that fails a test does not lose the plan for everyone; instead, the affected highly compensated or key employees lose the tax-free treatment of their own elections. Testing should be run before the plan year ends so the clinic has time to fix a problem. A Section 125 plan also needs a written plan document, and the clinic must keep elections irrevocable during the plan year except for IRS-permitted life events such as marriage, birth, or loss of other coverage.

The key employee concentration test in owner-heavy clinics

The key employee test is where small, owner-heavy clinics most often run into trouble. If a C corporation clinic has two owner-therapists on W-2 who each elect family coverage, and only a few lower-paid staff enroll, the owners' share of total pre-tax benefits can pass 25% quickly. The fix is usually to broaden enrollment among staff, for example with a plan design that makes enrolling simple during onboarding, rather than to reduce what the owners elect. Benecor runs this test before launch and again before year end.

2026 thresholds physical therapy owners should know

For 2026 testing, a highly compensated employee for Section 125 purposes is an officer, a more-than-5% owner, or an employee who earned more than $160,000 in the prior year. A key employee under IRC Section 416(i) is an officer earning more than $235,000 for 2026 (IRS Notice 2025-67), a more-than-5% owner, or a more-than-1% owner earning more than $150,000. Most practicing owner-therapists meet at least one of these definitions through ownership alone.

How long does it take to launch a Section 125 plan for a physical therapy clinic?

A Section 125 plan for a physical therapy clinic takes about five weeks from signed engagement to the first pre-tax payroll. The steps below follow the same sequence Benecor uses for other outpatient practices, adjusted for clinic schedules and owner-eligibility questions.

1. Week 1: Benecor confirms the clinic's entity type and whether the owner can participate, sorts the roster into full-time, part-time, and PRN staff, and delivers a signed savings projection.
2. Week 2: ERISA counsel drafts the plan adoption agreement and summary plan description, including a new-hire enrollment window.
3. Week 3: Staff enroll by QR code in a few minutes, often between patient visits or during a morning huddle.
4. Week 4: Election data goes to the clinic's payroll platform, such as ADP, Paychex, Gusto, or the payroll module tied to its practice management system. Deduction codes are set as pre-tax for federal income tax and FICA.
5. Week 5: The first pre-tax payroll runs, and the owner receives a compliance report confirming nondiscrimination testing passed.
