Med Spa Tax Deductions: What Aesthetics Practices Can Write Off in 2026

Ask a med spa owner what the practice can deduct and you will get the obvious list: product, payroll, rent, marketing. The list is rarely the problem. What costs real money is timing and placement: product bought but not yet used, a laser ordered in December and installed in January, owner health insurance never reported the way the IRS requires. Each is a deduction that disappears or lands in the wrong year.

This guide goes category by category through what a medical aesthetics practice can write off for 2026, where each rule has a catch, and what the Section 199A "health" label does to the final number.

Cost of treatment: injectables, consumables and the inventory problem

Neurotoxin, filler, biostimulators, threads, numbing cream, cannulas, peel solutions: all of it is deductible. The question is when. Product is inventory until it is used in a treatment or sold at the front desk, and the deduction follows the use, not the invoice. A practice that pays $320,000 for injectables and has $40,000 of it in the refrigerator on December 31 deducts $280,000.

Owners push back because the cash is gone. But "expense it when bought" produces a gross margin that swings with the vendor's rebate calendar and invites the IRS to recharacterize a year-end stock-up. Smaller practices can often use simplified inventory methods, yet even those deduct product when consumed, not when paid for. The fix is an inventory account, a monthly count, and cost of goods sold from units dispensed; our guide to inventory accounting for injectables and retail has the entries. Retail skincare bought for resale works the same way: cost is deducted as it sells, and the bottles on the shelf are an asset.

Devices and equipment: Section 179, bonus depreciation and financed purchases

Lasers, microneedling platforms, body-contouring devices, treatment chairs, autoclaves, computers and furniture are depreciable assets, and in 2026 almost all of them can be written off in full in the year they go into service, by one of two routes.

Section 179 lets a practice elect to expense up to $2,560,000 of qualifying purchases placed in service in tax years beginning in 2026, with the limit shrinking once total purchases pass $4,090,000. The catch: the deduction cannot exceed taxable income from the active conduct of the business, and the excess carries forward. Bonus depreciation, restored to 100% for qualified property acquired and placed in service after January 19, 2025, has no income limit and can create a loss that offsets other income on the owner's return, subject to the usual loss limitations.

In our practice we usually reach for bonus depreciation in a big device year and keep Section 179 for fine-tuning, because it can be applied asset by asset. Either way, two details decide the year. "Placed in service" means installed and ready for use, not ordered or paid for; a device delivered December 28 but first used January 6 is a 2027 deduction. And financing does not matter: a $150,000 laser on a five-year loan is fully deductible in the year it goes into service however little principal has been paid, with the interest deducted separately as it accrues. The trade-offs are covered in Section 179 vs. bonus depreciation for med spa equipment.

People, space and overhead

Wages, commissions, bonuses and the employer share of payroll taxes are deductible when paid (cash method) or when earned (accrual method), so a December commission accrual matters. Medical director fees are a deductible professional fee; for 2026 payments, issue a Form 1099 once you have paid the director $2,000 or more, even if the director bills through a corporation, because the corporate exception does not apply to medical and health care payments. If an injector is paid as a contractor the deduction survives, but the classification may not; see employee vs. independent contractor for med spas.

Rent, utilities, laundry and the security system are ordinary operating deductions. Build-out is different: interior improvements to a leased commercial space, such as treatment rooms, plumbing, lighting and flooring, generally qualify as qualified improvement property, a 15-year class eligible for both Section 179 and bonus depreciation, so a build-out can often be written off in the first year. Work on the building's structure or exterior does not qualify. The rest of overhead follows the rules in the table.

Owner-level deductions and what is not deductible

If the practice is an S corporation and you own more than 2% of it, health insurance premiums the company pays for you are deductible only if reported as wages on your W-2; you then take the self-employed health insurance deduction on your personal return. A SEP-IRA lets the business contribute up to 25% of your compensation, capped at $72,000 for 2026; for an S-corp owner the base is W-2 salary, one more reason the salary decision matters.

Some items are personal no matter how they are paid. Your own treatments, even if you call them device testing, are not deductible. Neither are personal skincare, ordinary clothing that could be worn outside work (scrubs and logo uniforms are fine), club dues, or IRS and state penalties; running them through the business creates taxable income to you or a distribution to unwind.

The QBI deduction and the "health" problem

Pass-through owners can deduct up to 20% of qualified business income under Section 199A, now permanent under the One Big Beautiful Bill Act. For 2026 the deduction is unrestricted while taxable income is below $201,750 (single) or $403,500 (joint). Above that it phases out over the next $75,000 or $150,000 for a specified service trade or business, and "health" is on the SSTB list; an owner of a health SSTB with taxable income above $276,750 single or $553,500 joint gets nothing.

Whether a med spa is a health SSTB is not settled by the name on the door. A practice whose income comes from services performed by licensed clinicians looks like health; a management services organization that provides space, staff, marketing and equipment to a professional entity for a fee may not be, and the answer turns on the facts. Two more points trip owners up: W-2 wages, including an S-corp owner's salary, are not QBI, and the deduction depends on household taxable income, not the practice's profit alone. See our guide to the QBI deduction and the IRS QBI page.

Worked example: a single-location practice

Take an illustrative single-location S corporation with $1,400,000 of revenue in 2026 and nine people on W-2 payroll, including the owner-injector. It bought $320,000 of injectables and consumables and ended the year with $40,000 on hand, sold retail product that cost $60,000, paid providers $380,000 and the owner a $120,000 salary, and put a $150,000 financed laser into service in March.

• Cost of treatment: $280,000. The $40,000 of unused product is inventory, deducted next year as it is used.
• Retail product cost: $60,000.
• Wages and commissions, including the owner's salary: $500,000, plus about $40,300 of employer payroll taxes (7.65% Social Security and Medicare, plus federal and Florida unemployment tax on the first $7,000 for each of the nine).
• Medical director fees: $24,000, with a 1099 issued.
• Rent $96,000, software $18,000, marketing $70,000, insurance $15,000, licenses and CE $8,000, merchant fees $35,000.
• Business meals: $4,000 spent, $2,000 deductible.
• Owner health insurance of $14,000, reported on the W-2, and a $30,000 SEP contribution (25% of the $120,000 salary).
• The laser: $150,000, deducted in full under bonus depreciation although little of the loan principal was paid this year.

Total deductions come to $1,342,300, leaving $57,700 of ordinary income on the owner's K-1. Had the practice expensed all $320,000 of product and left the laser on a multi-year schedule, the number would have been wrong in both directions. The owner's QBI is roughly that $57,700 (the salary is excluded), and with household taxable income below the threshold, the health SSTB question costs nothing this year.

Common mistakes, and the records that prevent them

The same errors recur in med spa books. Product is expensed at purchase, so December's bulk order flatters this year and starves the next. A device is deducted in the year the deposit was paid rather than the year it went into service. The owner's treatments are buried in cost of goods sold. Meals are deducted at 100%. The medical director is paid all year without a W-9. The S-corp owner's health premiums never reach the W-2. And Section 179 is elected in a loss year, where it only carries forward, when bonus depreciation would have produced a usable loss.

A deduction without a record is a negotiation. Keep injectable invoices (lot numbers tie to treatment records and inventory counts), payroll registers and commission calculations, the medical director's W-9 and agreement, equipment invoices with installation dates that prove when each device was placed in service, and meal receipts noting who and why. The IRS generally expects records kept three years after filing and employment tax records four years; see the IRS record retention guidance.

When to get help

If your books show product as an expense, no inventory account, no fixed asset schedule with placed-in-service dates and no accrual for provider commissions, your return is being prepared from numbers that cannot support the deductions in it. That is where a specialist pays for itself, ideally before the first device purchase of the year rather than in March.
