Medical Equipment Tax Deductions: Section 179 for Healthcare Practices

Medical and dental equipment is straightforward Section 179 property. The complexity for healthcare practices is rarely the equipment itself—it is that most practices are specified service trades or businesses with owners in the top bracket, which makes the qualified business income interaction and the entity structure more consequential than the depreciation election.

What Qualifies

Diagnostic imaging: X-ray, ultrasound, CT, MRI, DEXA, and C-arms. Dental: chairs, delivery units, intraoral and panoramic imaging, CAD/CAM mills, and sterilization systems. Surgical: tables, lights, electrosurgical units, arthroscopy and endoscopy towers, and surgical lasers. Aesthetic and dermatology lasers and IPL systems. Ophthalmic lane equipment, OCT, and femtosecond systems. Physical therapy and rehab equipment.

Also qualifying, and frequently missed: exam room furniture and cabinetry that is not permanently affixed, practice management and EHR software, telehealth carts, autoclaves, refrigeration for vaccines and specimens, waiting room furnishings, and the phone and network infrastructure.

Most medical and dental equipment falls in the 5-year or 7-year MACRS class. Ambulances and other emergency vehicles are 5-year property. Detail is in MACRS recovery periods by asset type.

Leasehold Improvements Are a Separate Analysis

This is where practice buildouts get expensive from a tax perspective. Cabinetry bolted to a wall, plumbing runs to operatories, lead-lined walls for imaging rooms, and dedicated electrical service are improvements to real property, not equipment. Absent planning they land in 39-year property.

Two provisions help. Qualified improvement property—interior improvements to nonresidential real property placed in service after the building was—is 15-year property and bonus eligible. And Section 179(f) reaches roofs, HVAC, fire protection, alarm, and security systems on nonresidential property.

For a large buildout, a cost segregation study separates the personal property and land improvements from the 39-year shell, often reclassifying 20% to 35% of the project cost into 5, 7, and 15-year lives. On a $1.5 million buildout that is a meaningful first-year swing. See cost segregation studies.

The QBI Problem

Health is a specified service trade or business under IRC Sec. 199A(d)(2). Above the taxable income thresholds, the 20% qualified business income deduction phases out entirely for SSTB owners.

That cuts both ways for equipment planning. If you are fully phased out of QBI, a large equipment deduction costs you nothing on the QBI side, because there is no deduction left to reduce. If you are inside the phase-in range, a Section 179 or bonus deduction reduces QBI and can claw back part of the 199A benefit while also reducing taxable income enough to partially restore it. The interaction is nonlinear and has to be modeled, not estimated.

Practices in the phase-in range sometimes find that a partial Section 179 election—deliberately deducting less than the maximum—produces a better combined result than full expensing. This is precisely the situation where Section 179's asset-by-asset control beats bonus depreciation's class-level election.

Entity Structure for Practices

Most practices are PCs, PLLCs, or S-Corps. The deduction flows through to the owner's return and reduces income taxed at the top marginal rate, which is the highest-value place for it to land.

The stock and debt basis limitation under IRC Sec. 1366(d) applies the same way it does for any S-Corp. A practice that finances a $400,000 imaging machine at the entity level may not have enough basis to absorb the full deduction. A shareholder loan made directly, rather than a corporate loan, creates debt basis and solves it.

Multi-owner practices have an additional issue: the deduction is allocated among owners, and if one partner is driving the purchase, the operating agreement's allocation provisions determine who actually gets the benefit. Special allocations are possible in a partnership-taxed entity and are not in an S-Corp, which allocates strictly pro rata.

The In-Service Date for Medical Equipment

This trips up more medical practices than any other industry, because medical equipment frequently requires installation, calibration, state registration, and sometimes a physicist survey before it can be used on patients.

An MRI delivered December 20 that is not sited, shielded, calibrated, and cleared for clinical use until January 15 was placed in service in January. The deduction belongs to the following tax year. Build the timeline backward from December 31 and include the regulatory steps, not just the freight.

The Numbers on a Typical Purchase

A practice acquiring a $400,000 imaging machine at 10% down and 3% closing is $52,000 out of pocket. The first-year deduction is the full $400,000. At a 35% blended rate that is $140,000 of tax savings, and the equipment simultaneously converts referred-out imaging revenue into in-house revenue. Full model on the equipment leasing page.

Frequently Asked Questions

Can a medical practice use Section 179?

Yes. Medical and dental equipment is tangible personal property used in an active trade or business and qualifies for Section 179 up to the annual limit, or for 100% bonus depreciation with no limit. Being a specified service trade or business affects the QBI deduction under IRC Sec. 199A but has no effect on depreciation eligibility.

Does buying equipment reduce my QBI deduction?

It reduces qualified business income, which reduces any 199A deduction you are receiving. For a practice fully phased out of QBI because of the SSTB rules, there is nothing to lose. For a practice inside the phase-in range, the interaction can be counterintuitive and a partial Section 179 election sometimes beats full expensing.

Are leasehold improvements to my office deductible in Year 1?

Not automatically. Improvements to real property generally default to 39-year recovery. Qualified improvement property is 15-year and bonus eligible, and Section 179(f) covers roofs, HVAC, fire protection, alarm, and security systems. A cost segregation study on a large buildout typically reclassifies a substantial share into shorter lives.

Can I deduct equipment financed through the vendor?

Yes, if the arrangement is a capital lease or installment purchase that makes you the tax owner. Many vendor financing programs are structured as $1 or 10% buyout leases, which qualify. A fair-market-value buyout lease is a rental, and you deduct the payments instead. Check the buyout clause before signing.

When is my new imaging machine considered placed in service?

When it is ready and available for its intended clinical use, which for medical equipment usually means after installation, calibration, and any required state registration or physicist survey. Delivery alone is not enough. Plan the acquisition so all regulatory steps clear before December 31.
