Tax Strategy for Physical Therapy Practice Owners (2026)

Physical therapy practices operate on thinner margins than most medical specialties, which changes the planning. A PT practice producing $340,000 of owner profit on $1,600,000 of revenue does not have the cushion a surgical practice has, so strategies have to be efficient rather than merely available.

The compensating advantage is that PT scales through additional locations, and each new clinic is a fresh build-out with a fresh deduction.

Build-Outs Are the Recurring Opportunity

A PT clinic build-out reclassifies well, generally 30% to 45% of construction cost. Rubber and specialty flooring in the gym area, treatment table plumbing and dedicated electrical, decorative and accent lighting, casework and reception millwork, sound masking, and privacy partition systems are five-year personal property.

The structural remainder of an interior build-out in leased space generally qualifies as qualified improvement property under IRC Sec. 168(e)(6), carrying a 15-year life with full bonus eligibility under IRC Sec. 168(k). Between the two, a $480,000 clinic build-out is often close to fully deductible in the opening year.

For an owner opening one clinic a year, this becomes an annual deduction of $400,000 to $600,000 that offsets the profit generated by the mature locations. Growth funds its own tax efficiency, which is the single most useful structural feature of a multi-site PT business.

Equipment adds to it. Treatment tables, traction units, modalities, exercise and rehab equipment, dry needling and laser equipment, and practice management hardware are five-year property, fully deductible in the placed-in-service year.

The SSTB Limitation and What It Costs

Physical therapy is health services under IRC Sec. 199A, a specified service trade or business. Above the phase-out range, the qualified business income deduction is unavailable entirely.

For a practice with $500,000 of qualified business income, that is a $100,000 deduction lost. Below the threshold it is fully available, which means multi-owner practices where each owner's share falls below the threshold may still claim it while a single-owner practice at the same total income does not.

This is one of the few places where ownership structure genuinely changes the answer. A practice with three equal owners each showing $220,000 of qualified business income may have the deduction available where a sole owner with $660,000 does not. Practices contemplating partner buy-ins should model this, because it can offset a meaningful portion of the economic cost of admitting a partner.

Entity and Compensation

S corporation treatment is standard. Because the QBI deduction is generally unavailable above the threshold, the salary analysis is a straightforward payroll tax question without the wage limitation tradeoff.

Reasonable compensation for a PT owner should reflect clinical production plus management. An owner treating patients full time while managing three clinics has a compensation profile with two components, and the analysis is stronger when it accounts for both explicitly rather than picking a round number.

Practices with associate therapists should also examine whether the compensation model creates the right incentives without creating tax problems. Productivity bonuses paid as W-2 compensation are straightforward. Profit distributions to non-owner therapists are not, and arrangements that look like equity without being equity create their own issues.

Retirement Plans on a Thin Margin

PT practices have more employees per dollar of owner profit than most medical specialties, which makes aggressive plan design harder. A cash balance plan that costs $45,000 in staff contributions to deliver $150,000 of owner contribution is still worth doing, but the ratio needs checking rather than assuming.

A safe harbor 401(k) with new comparability profit sharing is the practical base. Where the workforce skews young, which it usually does in PT, cross-testing performs well and the owner can capture a large share of employer contributions.

For multi-site practices, plan design should account for the aggregate workforce across entities. Controlled group and affiliated service group rules under IRC Sec. 414(b), (c), and (m) treat commonly owned entities as a single employer for plan testing. Practices that set up each clinic as a separate LLC and assume separate plans are available are frequently wrong about that.

Owning the Real Estate

PT clinics are good real estate tenants and many owners eventually buy their buildings. A cost segregation study on a clinic building typically reclassifies 20% to 30% of depreciable basis, and the build-out inside reclassifies far higher.

The self-rental rules under Treasury Regulation Sec. 1.469-2(f)(6) govern how the resulting loss is used. Net rental income from property leased to a business you materially participate in is recharacterized as non-passive, but a net rental loss generally is not, which can leave a large depreciation deduction suspended.

A grouping election under Treasury Regulation Sec. 1.469-4 frequently resolves this where the requirements are met. It should be evaluated before the study is commissioned, because the sequence affects whether the deduction is usable in the year it is generated.

Worked Example: Three-Clinic Practice

A 46-year-old owner runs three clinics with $2,900,000 of revenue and $610,000 of profit before owner compensation, with 24 employees, structured as an S corporation with a $230,000 salary.

A fourth clinic build-out of $520,000 plus $140,000 of equipment is placed in service in the current year and is substantially fully deductible between five-year property, QIP, and equipment.

A safe harbor 401(k) with new comparability directs $69,000 to the owner at $27,000 of staff cost across the controlled group.

A look-back cost segregation study on the first clinic build-out completed four years ago, filed with Form 3115, produces a $186,000 catch-up deduction.

Taxable income falls by roughly $915,000 in the year, which for a practice with $610,000 of profit creates a loss carryforward that shelters the following year as well.

Frequently Asked Questions

Does physical therapy qualify for the QBI deduction?

Physical therapy is health services and therefore a specified service trade or business under IRC Sec. 199A. Above the phase-out range the deduction is unavailable. Below the threshold it is fully available, which is why multi-owner practices sometimes preserve it where a sole owner would not.

How much of a PT clinic build-out is deductible in year one?

Typically 30% to 45% reclassifies to five-year personal property, with most of the balance qualifying as 15-year QIP under IRC Sec. 168(e)(6) with full bonus eligibility. Between the two, a leasehold build-out is often close to fully deductible in the opening year.

Can each of my clinics have its own retirement plan?

Usually not in the way owners expect. Controlled group and affiliated service group rules under IRC Sec. 414(b), (c), and (m) treat commonly owned entities as a single employer for plan testing. Separate LLCs do not create separate testing groups when ownership overlaps.

Should I buy my clinic building?

Often yes, and a cost segregation study typically reclassifies 20% to 30% of the building plus far more of the build-out. But the self-rental rules under Treas. Reg. Sec. 1.469-2(f)(6) determine whether the loss is usable currently, so evaluate a grouping election before commissioning the study.

Does adding a partner change my tax position?

It can, meaningfully. If each owner's share of qualified business income falls below the IRC Sec. 199A threshold, the deduction that was unavailable to a sole owner may become available. This should be modeled as part of the economics of any buy-in.
