Veterinary Equipment Depreciation: Section 179 and Bonus Depreciation

Veterinary practices are capital-intensive businesses. A single digital X-ray system can run $50,000 to $150,000, an ultrasound unit $20,000 to $80,000, and a fully equipped dental suite $15,000 to $40,000. When you add surgical tables, anesthesia machines, autoclaves, and the building improvements needed to house all of it, the total capital outlay can climb into the hundreds of thousands within a few years of opening or expanding a clinic. The good news is that the tax code offers several powerful tools to accelerate how quickly you recover those costs, and recent legislation has made those tools even more generous.

This guide walks through how Section 179, bonus depreciation, and cost segregation work for veterinary practices, what changed under OBBBA, and how to structure equipment purchases for maximum tax benefit.

Can I deduct the full cost of equipment in year one?

Yes, in most cases. There are two primary mechanisms that allow a veterinary practice to deduct the full purchase price of equipment in the year it is placed in service: the IRC 179 election and bonus depreciation under IRC 168(k).

Section 179 allows a business to elect to expense (rather than capitalize and depreciate) the cost of qualifying property, up to an annual dollar limit. For tax year 2026, that limit is $2,560,000. The deduction begins to phase out dollar for dollar once total qualifying property placed in service during the year exceeds $4,090,000. For the vast majority of veterinary practices, even those making significant capital investments in a single year, total equipment purchases will fall well below the phase-out threshold.

Bonus depreciation works differently. Rather than an elected expense with a dollar cap, bonus depreciation is an automatic additional first-year depreciation allowance applied to the depreciable basis of qualifying property. Under the Tax Cuts and Jobs Act (TCJA) of 2017, bonus depreciation was set at 100% for property acquired and placed in service from September 27, 2017 through December 31, 2022, then scheduled to phase down: 80% in 2023, 60% in 2024, 40% in 2025, 20% in 2026, and 0% in 2027.

The One Big Beautiful Bill Act changed that trajectory. OBBBA restored 100% bonus depreciation permanently for qualified property acquired after January 19, 2025. There is no sunset date. For a veterinary practice purchasing a new digital radiography system or ultrasound unit today, the full cost can be deducted immediately through bonus depreciation alone, without needing to make a Section 179 election at all.

What qualifies as Section 179 property?

Section 179 property must be tangible personal property (or certain other qualifying property) that is purchased for use in the active conduct of a trade or business. For a veterinary practice, the qualifying property list is extensive. It includes diagnostic imaging equipment such as digital X-ray systems and ultrasound machines, surgical equipment including tables, lights, and instrument sets, dental units and dental X-ray systems, anesthesia machines and monitoring equipment, autoclaves and sterilization systems, examination tables, kennels and caging systems, laboratory analyzers, and computer systems including practice management software.

Leasehold improvements to a veterinary clinic building can also qualify for Section 179, provided they are improvements to the interior of a nonresidential building that is already placed in service. This category, sometimes called qualified improvement property (QIP), covers renovations like new flooring, updated plumbing for surgical suites, HVAC modifications, and expanded treatment areas.

Property that does not qualify includes land, buildings themselves (the structure, not improvements to it), property used outside the United States, and property acquired from related parties. If you are purchasing equipment from a family member or an entity you control, the Section 179 deduction is not available for that transaction.

The entity structure of your practice matters here as well. If your veterinary practice operates as a sole proprietorship, partnership, S corporation, or C corporation, the Section 179 deduction is generally available at the entity level. However, the deduction passes through to owners on their individual returns for pass-through entities, and it cannot exceed the owner’s taxable income from the active conduct of the business. Planning around entity structure is worth considering before making large capital purchases. For a deeper look at how entity choice affects tax outcomes for veterinary practices, see our guide on veterinary practice entity structure.

How does bonus depreciation work after OBBBA?

The OBBBA provision is straightforward for property acquired after January 19, 2025. For any qualifying property that a veterinary practice acquires and places in service after that date, 100% bonus depreciation applies. The practice can deduct the entire cost in the first year. There is no dollar limit on bonus depreciation (unlike Section 179’s $2,560,000 cap), and the deduction can create or increase a net operating loss (NOL), which Section 179 cannot.

This is a significant distinction. If your veterinary practice has a year with heavy capital spending but modest income, Section 179 would be limited to taxable income from the business, while bonus depreciation could generate a loss that carries forward to offset future income. For a practice in an expansion year, where revenue has not yet caught up to the investment, bonus depreciation may be the more valuable tool.

One important caveat applies to property acquired before January 20, 2025. If your practice purchased equipment in 2024 or early 2025 (before the OBBBA cutoff date) and placed it in service in 2026, the old TCJA phase-down schedule still governs that property. The bonus depreciation rate for such property placed in service in 2026 is 20%, not 100%. The remaining 80% of the cost would be recovered through regular MACRS depreciation over the asset’s class life (typically five or seven years for veterinary equipment).

This creates a practical planning point. If you signed a purchase agreement for a large piece of equipment in late 2024 but have not yet placed it in service, the acquisition date (when the contract was binding) determines which bonus depreciation rate applies, not the date of delivery or installation. Review the timing of any pending equipment purchases carefully with your tax advisor.

What does equipment cost and its depreciation impact?

To put the numbers in perspective, here are common equipment categories and their approximate price ranges for a mid-size veterinary practice:

• Digital X-ray system: $50,000 to $150,000
• Ultrasound unit: $20,000 to $80,000
• Surgical tables: $5,000 to $25,000
• Dental unit with X-ray: $15,000 to $40,000
• Anesthesia machine: $10,000 to $30,000
• Autoclave/sterilization: $3,000 to $15,000

A practice outfitting a new location or replacing aging equipment could easily place $200,000 to $400,000 of qualifying property in service during a single year. Under current law, the entire amount can be deducted in year one through either Section 179 or bonus depreciation, assuming the property was acquired after January 19, 2025.

Should I use Section 179, bonus depreciation, or both?

This is one of the most common questions veterinary practice owners ask, and the answer depends on several factors specific to your situation.

Section 179 and bonus depreciation can be used together on the same asset. A common strategy is to apply Section 179 to a portion of the cost and bonus depreciation to the remainder, though in practice this is most useful when there is a reason to limit the total deduction (for example, to preserve income for other deduction thresholds or to avoid creating an NOL you do not want).

For most veterinary practices making equipment purchases in 2026 or later (acquired after January 19, 2025), bonus depreciation alone will accomplish the same result as Section 179 for the first-year deduction, with fewer restrictions. Bonus depreciation has no dollar cap, no taxable income limitation, and applies automatically unless the taxpayer elects out. Section 179 is capped at $2,560,000, cannot exceed the business’s taxable income, and requires an affirmative election on the tax return.

There are situations where Section 179 is preferable. If you are purchasing used equipment (previously owned by someone else), Section 179 has always allowed used property, while bonus depreciation for used property was a TCJA addition that OBBBA extended. In most current scenarios both tools cover used property, but the rules have changed multiple times, so confirm eligibility with your preparer. Section 179 is also useful for state tax planning, because some states conform to Section 179 but do not conform to federal bonus depreciation. In those states, taking the deduction under Section 179 rather than bonus depreciation may produce a better state tax result.

The choice also intersects with your practice’s entity structure and the owner’s individual tax situation, particularly for pass-through entities where the deduction flows to the owner’s personal return. If you are evaluating a major equipment purchase alongside a potential sale or acquisition of a practice, the depreciation strategy becomes part of a larger transaction structure. For guidance on how purchase price allocation affects depreciation in a veterinary practice acquisition, see our guide on buying and selling a veterinary practice.

The mechanics of choosing between Section 179 and bonus depreciation are not unique to veterinary practices. Our guide on Section 179 versus bonus depreciation versus MACRS walks through the same tradeoffs in a different capital-intensive industry, and the underlying rules apply the same way to clinic equipment.

What is cost segregation, and does it apply to my clinic?

Cost segregation is a tax planning strategy that applies to buildings, not equipment. When a veterinary practice owns (or constructs) its clinic building, the structure is generally depreciated over 39 years under MACRS for nonresidential real property. That is a slow recovery. Cost segregation accelerates it.

A cost segregation study, conducted by an engineer or specialized firm, identifies building components that can be reclassified from 39-year real property into shorter-lived personal property categories: 5-year, 7-year, or 15-year property. In a veterinary clinic, reclassifiable components commonly include specialized electrical wiring for diagnostic equipment, plumbing for surgical suites and treatment areas, built-in cabinetry and casework, flooring in clinical areas, security systems, signage, parking lot paving and landscaping, and dedicated HVAC components serving specific clinical zones.

Once reclassified, these components qualify for accelerated depreciation, including bonus depreciation at 100% under OBBBA for property acquired after January 19, 2025. For a veterinary clinic building that cost $1,000,000 to construct, a cost segregation study might reclassify 20% to 35% of the building cost (roughly $200,000 to $350,000) into shorter-lived categories eligible for immediate deduction. At a 35% marginal tax rate, that reclassification could produce $70,000 to $122,500 in additional first-year tax savings compared to straight-line depreciation over 39 years.

Cost segregation studies typically cost $5,000 to $15,000 for a veterinary clinic, making the return on investment highly favorable when the building cost exceeds roughly $500,000. The study can also be performed retroactively on buildings already placed in service, with the catch-up deduction claimed through a change in accounting method (Form 3115) rather than amending prior returns. For a deeper look at how 100% bonus depreciation changed the math on cost segregation studies generally, see our guide on cost segregation after the Big Beautiful Bill. And if your clinic building sits in a separate entity you own, the self-rental and structuring questions that come with it are covered in our guide on owning your veterinary clinic building.

One consideration for practice owners planning to sell: accelerated depreciation on building components is subject to depreciation recapture under IRC 1245 (for personal property) and IRC 1250 (for real property) upon sale. The recapture is taxed at ordinary income rates (for Section 1245 property) or a maximum 25% rate (for unrecaptured Section 1250 gain). If a sale is on the near-term horizon, the upfront tax savings from cost segregation should be weighed against the recapture tax at disposition.

What records do I need to keep?

The IRS expects taxpayers claiming accelerated depreciation to maintain records that substantiate both the cost and the placed-in-service date of each asset. For a veterinary practice, this means keeping purchase invoices, delivery confirmations, installation records, and payment documentation for every piece of qualifying equipment. If you are claiming cost segregation, the study itself (and the engineer’s report) becomes part of your documentation.

For Section 179, the election is made on Form 4562 (Depreciation and Amortization) filed with the return for the year the property is placed in service. The election is irrevocable once made (for that tax year), though it can be revoked by filing an amended return before the due date. Bonus depreciation, by contrast, applies automatically unless the taxpayer elects out on a timely filed return, and that election out is also generally irrevocable.

Maintaining a fixed asset schedule, whether in your practice management software, accounting system, or a standalone spreadsheet, is essential. Each asset should be tracked with its description, cost, acquisition date, placed-in-service date, depreciation method, and the IRC section under which the deduction was claimed. This schedule is your first line of defense in an audit and the foundation for calculating gain or loss on disposition.

How do state taxes affect the calculation?

State conformity to federal depreciation rules varies widely. Some states fully conform to both Section 179 and bonus depreciation at the federal limits. Others decouple from bonus depreciation entirely, requiring the taxpayer to use regular MACRS for state purposes while claiming accelerated depreciation federally. A handful of states impose their own, lower Section 179 limits.

The practical effect is that a veterinary practice claiming $300,000 in federal bonus depreciation might have $0 of that deduction recognized by the state, resulting in a higher state tax bill in year one offset by larger state depreciation deductions in future years. This creates a timing difference, not a permanent one, but the cash flow impact in the first year matters for planning.

If your practice operates in a state that decouples from federal bonus depreciation (California and New York are notable examples), coordinating the federal and state depreciation elections is important. In some cases, electing Section 179 instead of bonus depreciation for certain assets can produce a better combined federal-and-state result, since more states conform to Section 179 than to bonus depreciation.

Your tax preparer should model both the federal and state effects before finalizing the depreciation elections on your return. This is especially true for multi-state practices or owners who are residents of a different state than where the practice operates.

Does the deduction still apply if I take a loan?

Yes. The tax deduction for depreciation (whether Section 179 or bonus depreciation) is based on the cost of the property, not on how the purchase is funded. If your veterinary practice finances a $100,000 digital X-ray system with a five-year equipment loan, you can still deduct the full $100,000 in year one under Section 179 or bonus depreciation. You are also entitled to deduct the interest on the loan as a business expense (subject to the business interest limitation under IRC 163(j), which most veterinary practices will not exceed).

This makes financed equipment purchases particularly powerful from a cash flow perspective. The practice takes delivery of the equipment, begins using it to generate revenue, deducts the full cost in year one to reduce its tax liability, and pays for the equipment over time. The tax savings from the immediate deduction often cover a significant portion of the first year’s loan payments.

Leased equipment is treated differently. If the lease is a true lease (an operating lease where the lessor retains ownership), the practice deducts the lease payments as a business expense rather than claiming depreciation. If the lease is structured as a capital lease (essentially a financing arrangement where the practice will own the equipment at the end), it is treated as a purchase for tax purposes, and depreciation deductions apply. The distinction depends on the terms of the lease agreement, so review the structure with your CPA before signing.

Next steps for your practice

Equipment depreciation planning is not something to figure out after the purchase is made. The acquisition date, placed-in-service date, entity structure, state of operation, and overall income picture all affect which depreciation method produces the best result. For practices planning a major equipment purchase, building a new clinic, or evaluating whether a cost segregation study is worth the investment, the analysis should happen before the money is committed.

Blue Cloud CPA works with veterinary practice owners on exactly these questions. Our $250 tax assessment reviews your practice’s current tax position, identifies depreciation opportunities you may be leaving on the table, and provides a clear recommendation on how to structure upcoming equipment purchases for maximum benefit. If you are considering a purchase of $50,000 or more in equipment, or if you own your clinic building and have never had a cost segregation analysis performed, the assessment is a practical starting point.
