Medical Spa Entity and Estimated Taxes: The Management Company, the Professional Entity, and the December That Sells Next Year's Treatments

Med spa owners decide their entity inside the corporate practice rules and their estimates around the holidays. Entity — one entity or two. The one-entity med spa (states without the corporate practice doctrine, or a physician-owned med spa anywhere): an LLC or corporation with the S election once the profit clears the owner's salary — the payroll exists (injectors, aestheticians, front desk), so the election's incremental cost is the 1120-S and basis tracking; the owner's reasonable salary is the market for the owner's role (a physician-owner's is a physician's compensation for the owner's clinical work plus management; a nurse practitioner-owner's is a nurse practitioner's; a non-clinical owner's is a med spa manager's or director's, US$60,000 to US$110,000). The two-entity med spa (the management services organization structure — the medical spa taxes guide): the management company (owned by the non-physician; holds the lease, the equipment, the retail line, the non-clinical staff; earns a management fee from the professional entity plus its own retail and non-medical service revenue) and the professional entity (owned by the medical director or another licensed practitioner; holds the clinical practice, employs the clinical staff, pays the management fee); each is its own tax entity with its own election — the management company as an S corporation with the owner's salary; the professional entity usually as an S corporation or a disregarded entity of the physician, often with little profit after the management fee (by design — the fee is set at fair market value for the services and assets the management company provides, and the professional entity's residual profit belongs to the physician). The management fee — the tax and legal center: the fee must be fair market value (a fixed monthly fee, or cost plus a markup, documented by a valuation where the amounts are large) — because the anti-kickback and fee-splitting rules forbid a fee that is a disguised percentage of the physician's professional revenue in many states, and because the tax law allows the IRS to reallocate income between commonly controlled businesses (section 482) and, where the entities share 50 percent or more common ownership, to treat the part of the management company serving the professional entity as a specified service trade; a fee set to strip all the professional entity's profit into the management company so the owner's QBI deduction survives is the arrangement most likely to be challenged; set honestly, the structure produces a management company whose income is management fees, retail, and non-medical services (generally non-SSTB when the two entities don't share 50 percent or more common ownership — the QBI deduction applies at every income, subject to the wage limitation the non-clinical payroll satisfies) and a professional entity whose income is medical (SSTB — the deduction phases out above the range). The liability floor: malpractice (the practitioners' — the professional entity's policy and each injector's), the device injury (a laser burn), the product claims (the retail line), the employment claims, the lease — the entities separate the liabilities (the management company's assets are not exposed to the clinical practice's malpractice claims, which is an additional reason for the structure), with each entity's insurance as the first line. The exit: med spas are bought by aesthetic chains and private equity platforms — the buyer acquires the management company (the assets, the brand, the staff, the lease, the patient relationships the management agreement supports) and enters a new management agreement with the professional entity (or a new one owned by the buyer's affiliated physician); the seller's asset sale from a pass-through is single-taxed (capital gain on goodwill, ordinary on inventory and equipment recapture). Estimated taxes — December and the device year. The shape: med spa revenue has a spring rise (pre-summer body treatments and laser hair removal), a steady summer and fall of injectables (the toxin's three-to-four-month cycle brings patients back on schedule), and a December that is the year's largest sales month — packages, memberships renewed, and gift cards sold for the holidays, all cash-method income when received (the taxes guide), much of it for treatments delivered in the first half of next year; so the fourth quarter's income is inflated by next year's services, and the January 15 installment (or the December withholding) carries it; a med spa whose December prepaid sales are large examines the accrual method with the one-year deferral (a Form 3115 change that moves the unearned portion into the following year — no later, even for a treatment delivered after it). The device year: a med spa that adds a laser or a body-contouring device (six figures) expenses it under section 179 or bonus depreciation — cutting the year's taxable profit by the device's cost; the fall recompute catches it, and the purchase's timing (December versus January placement in service) is decided with the December sales in view (a large December of package sales and a device placed in service the same month offset each other). The S corporation owner (either entity): the owner's salary withholding covers the tax on salary and projected distributions — deemed paid evenly across the year regardless of when withheld — through the staff's payroll, with the fall recompute setting the December payroll's withholding for December's prepaid sales and any device; in the two-entity structure, each owner's withholding runs through their own entity's payroll, and the non-physician owner's projection runs on the management company's profit (the fee, retail, non-medical services less its costs). What the estimate includes: federal income tax on projected profit by entity; self-employment tax only for a disregarded professional entity's physician-owner; the state's estimates; the QBI deduction (the management company's — the professional entity's phases out above the range); the device write-offs; the inventory's year-end count (a December stock-up of injectables for January's demand is cash out with no deduction until used); the prepaid sales under the method; and the retail line's sales tax (a liability, not income). The quarterly check: treatments and units by line; the toxin cycle's return rate; packages and memberships sold and their outstanding balances; the inventory position; device purchases; profit by entity against withholding; the adjustment. The failure modes: the management fee set to strip the professional entity's profit (a look-through and a regulatory exposure); December's prepaid sales not in the fourth quarter's projection; the December injectable stock-up deducted when bought; a device placed in service without the recompute; and the gift cards treated as deferred under the cash method. The calendar: January — last year closed (inventory counted; prepaid balances tracked; the management fee reconciled between entities), the withholding set by entity, the device plan noted; quarterly — the check; October — the recompute (December's expected sales, the device timing, the fee's annual review); December — the sales, the count, the payroll cure.

Key takeaways

• One entity where the corporate practice rules allow it; two in the management services structure — a non-physician-owned management company and a physician-owned professional entity, each with its own election.
• The management fee must be fair market value — documented, not a disguised percentage of professional revenue — because fee-splitting rules, section 482, and the specified-service look-through all reach an arrangement designed to strip the professional entity's profit.
• Set honestly, the management company's income is generally non-SSTB (management fees, retail, non-medical services — the QBI deduction applies) while the professional entity's is health (phases out above the range).
• December sells next year's treatments: packages, memberships, and gift cards are cash-method income when received — the fourth quarter carries them; the accrual method's one-year deferral is the alternative for large prepaid balances.
• A device year erases the tax — recompute in the fall; a December stock-up of injectables is cash out, deducted only as used.
• Owners run withholding through their own entity's payroll, set in January and cured in December.

The medical spa owner's one-page plan

Structure: one entity or MSO + professional entity (healthcare counsel's review); fair-market management fee documented; each entity's election. Salaries: physician, nurse practitioner, or manager market plus management. QBI: management company (non-SSTB, wage limitation) vs professional entity (SSTB). Estimated taxes: withholding by entity; October recompute for December's prepaid sales, devices, and the fee review; December count and payroll cure; the method for prepaid balances. One page — and the fee's documentation is the line that holds the structure together.

Worked example

The two-entity med spa from the taxes guide: the management company (S corporation, the non-physician owner) earns a US$62,000 monthly management fee (a fixed fee supported by a valuation of the space, equipment, non-clinical staff, marketing, and systems it provides — about US$744,000 a year), US$140,000 of retail, and US$90,000 of facials, and nets US$310,000 to the owner after its costs — a US$95,000 med spa director's salary, a US$215,000 distribution, the QBI deduction on the management company's income supported by the non-clinical payroll. The professional entity (the medical director's S corporation) nets US$120,000 after the fee, the clinical payroll, and the injectables — health-field income, the director's QBI deduction on it phased out if her taxable income is above the range. October recompute: December is projected at US$260,000 of package, membership, and gift card sales (cash-method income across both entities by where the sale is booked), a new body-contouring device (US$140,000) will be placed in service in December by the management company (section 179), and the professional entity plans a US$60,000 injectable stock-up for January's demand (inventory — deducted as used next year, not in December); the owner's December payroll withholding is set for the net of the device and the December sales. The fee's annual review confirms it remains at fair market value after the new device (the management company provides more equipment — the valuation supports a modest increase next year). The competing med spa whose owner set the management fee at 90 percent of the professional entity's collections: a fee-splitting complaint to the medical board, and an adviser's warning that the arrangement's QBI result would not survive a look-through.

Practitioner note

A medical spa's entity planning happens inside the corporate practice rules: often two entities, a management company and a physician-owned practice, connected by a management fee that has to be fair market value — because the fee-splitting rules, section 482, and the specified-service look-through all reach an arrangement designed to strip the practice's profit. Our med spa plans document that fee with a valuation, run each owner's withholding through their own entity's payroll, and recompute every October for the December that sells next year's treatments and the device placed in service the same month — because the prepaid packages are income when received and the injectable stock-up isn't a deduction until it's used.
