Medical equipment depreciation: What practice owners need to track and why it matters

Why depreciation is a bookkeeping problem, not just a tax problem

A practice buys a $180,000 imaging unit in March, runs it hard all year, and never thinks about it again until the accountant asks for the asset list in February. By then the install date is fuzzy, the financing paperwork is in a drawer, and nobody recorded when the machine actually went live. The practice still gets a deduction. What it does not have is a set of books that tells the truth about what that equipment is worth and what it cost to own this year.

That is the gap most owner-run practices live in. Depreciation gets treated as a once-a-year tax chore handled by someone outside the practice, when it is really a continuous bookkeeping function that shapes every financial statement in between. A practice that tracks it properly can say what its equipment is worth, what its true overhead is, and whether it is ready to borrow or sell. A practice that does not is guessing on all three.

This is interpretation-light territory where the rules are public and stable, but the discipline is where practices slip. Numetix works with medical and dental practices on exactly this, and the pattern is consistent: the equipment is expensive, the schedules are neglected, and the cost shows up later, at the worst possible time.

How does the IRS classify medical equipment for depreciation

By recovery period, and the class your equipment lands in changes the entire schedule. Under the Modified Accelerated Cost Recovery System, the standard tax method described in IRS Publication 946, every depreciable asset is assigned to a class with a set recovery period. Most business equipment falls into the 5-year or 7-year classes, and that split is exactly where medical practices need to pay attention.

High-technology medical equipment has a specific treatment. The IRS recovery-period tables assign high-technology medical equipment, defined under the relevant code section, a 5-year recovery period. Much of the other clinical and office equipment in a practice falls into the 7-year class. The practical consequence is that "equipment" is not one line on your books. An imaging system and an exam-room cabinet can depreciate on different schedules, and lumping them together produces a fixed-asset register that does not reconcile to anything.

So what for you: a single catch-all "equipment" account is the first thing to fix. Each asset class needs to be tracked separately so the depreciation schedule reflects how the IRS actually treats it, and so your monthly financial statements stay accurate.

When does depreciation actually start

When the equipment is placed in service, which is not the same as when you paid for it. IRS guidance is specific on this point: an asset is placed in service when it is ready and available for its intended use, not on the purchase date and not on the delivery date. A machine that arrives in December but is not installed and operational until January is placed in service in January, and that is when its depreciation clock starts.

For a medical practice this matters more than it sounds, because the gap between purchase and go-live can span a tax year. Equipment that needs installation, calibration, staff training, or facility modification before it can treat patients is not in service until all of that is done. If your books record depreciation from the purchase date instead of the placed-in-service date, the timing is wrong, and the error flows into your financial statements and your tax return alike.

So what for you: capture the placed-in-service date for every asset at the time it goes live, not months later from memory. It is a one-line note when it happens and a reconstruction headache when it is not.

Book depreciation and tax depreciation are not the same number

Here is the distinction that trips up practices relying on a generic bookkeeper. The accelerated tax method is built to front-load deductions and is used on the tax return. It does not reflect how the asset's value actually declines in even economic terms, and it is not what belongs on financial statements prepared to show operational reality. Book value and tax basis diverge from the first year, and both are legitimate, for different audiences.

A practice that records only the tax depreciation number has financial statements that answer the IRS's question but not the owner's. The owner wants to know what the equipment is genuinely worth and what it is truly costing the practice to operate. That is the book view. Tracking both, with a clean depreciation schedule per asset, is what separates real practice bookkeeping from bank reconciliation with a healthcare label on it.

What clean depreciation records are actually worth to a practice

More than a correct tax return. The real payoff shows up at the three moments when someone outside the practice reads your books closely: a loan, a partner buy-in, and a sale. In every one of those, the first thing a lender, an incoming partner, or a buyer examines is the fixed-asset register and its depreciation. It tells them whether the balance sheet is trustworthy and whether the practice is run with discipline.

A practice with a current accumulated depreciation schedule walks into those conversations with credibility. A practice that has to reconstruct its asset history walks in looking disorganized, which is precisely the impression that lowers a valuation or stalls a loan. This is why depreciation belongs in the same category as your other core records, the ones that determine whether the practice is financeable and sellable, not in a once-a-year tax folder.

There is also a planning dimension. The tax code does include provisions that let businesses accelerate deductions on qualifying equipment, and those provisions change. This is exactly the kind of interpretation-heavy decision to make with your CPA and against current IRS guidance, not from a blog or a memory of last year's rules. What the practice owns and controls is the bookkeeping discipline underneath: accurate classes, correct dates, clean schedules. Get that right all year, and the tax strategy on top of it has something solid to stand on.

Frequently asked questions

What depreciation method do medical practices use

For tax purposes, most practices use the Modified Accelerated Cost Recovery System described in IRS Publication 946, which assigns each asset a class and recovery period and front-loads the deduction. For the practice's own financial statements, a straight-line book method often gives a truer picture of how the asset's value declines. The two coexist on purpose, one for the tax return and one for operational reality, which is why tracking both is the standard for practices that want accurate books.

Is the depreciation schedule something my bookkeeper handles or my CPA

Both, in different ways, and that is the point. The CPA sets the tax depreciation strategy and files it, typically on Form 4562. The bookkeeper, or your accounting partner, maintains the fixed-asset register all year so the placed-in-service dates, asset classes, and accumulated depreciation are accurate when the CPA needs them. A practice that leans only on the CPA at year-end loses the month-to-month accuracy that makes financial statements usable.

Why does the placed-in-service date matter so much

Because it determines which tax year depreciation begins and how the first year's numbers look. Equipment bought in one year but not operational until the next is placed in service in the later year, per IRS guidance, and recording it from the purchase date instead shifts deductions and distorts both the financial statements and the return. For high-cost medical equipment with installation and training lead times, that gap is common enough to be worth capturing deliberately at go-live.
