Medical Equipment Deductions: Section 179, Bonus and Practice Basis
By AE Tax Advisors · Published 2026-08-05 · Updated November 8, 2026.
A medical practice's equipment purchase may qualify for accelerated deductions, but the invoice amount is not a guaranteed current write-off. Start with who owns the equipment, what was purchased, when it was ready for use and the practice's tax classification.
Separate equipment from the buildout
Imaging systems, chairs, instruments, software, installation and building work may follow different rules. Obtain itemized contracts and allocate costs using supportable classifications. A standard percentage of the renovation budget is not a cost segregation conclusion.
Compare Section 179 and bonus
Section 179 has dollar, phaseout and business-income limitations, with elections and carryforward rules. Bonus depreciation has its own eligible-property and timing requirements. Use the current tax-year rules rather than an old threshold from the purchase proposal.
Decide at the correct taxpayer level. A deduction that is available to the practice may still be limited on a partner's or shareholder's return.
Distinguish a lease from a financed purchase
Marketing terms such as lease-to-own do not determine tax ownership. Review the agreement, buyout terms, payment obligations and economic arrangement. A true lessee generally analyzes rent; a tax owner analyzes asset basis and depreciation.
Financing can affect cash flow without postponing every deduction, but a low down payment does not prove eligibility for an immediate write-off of the full price.
Review practice and owner limitations
An S corporation loan does not automatically create shareholder debt basis. Partnerships have different liability rules. At-risk, passive and excess-business-loss limits may also apply.
Medical services can fall within the QBI specified-service rules. Review taxable income and the current-year limits alongside compensation, benefits and retirement contributions.
Model the business result
Compare the equipment's expected revenue and operating costs, financing, deduction actually usable, state treatment and eventual sale. A tax deduction does not establish that adding the service is profitable.
Request an equipment deduction review with the contract, installation timeline, entity return and owner basis schedules.
Frequently Asked Questions
Does a financed equipment purchase guarantee a full current deduction?
No. Tax ownership, service date, asset eligibility and taxpayer-level limits must be checked.
Does a corporate equipment loan create shareholder basis?
Not automatically. S corporation shareholder debt basis has separate requirements.
