Every year we watch practice owners make the same avoidable mistake. They decide to buy a piece of equipment, sign the purchase agreement, take delivery, and only later ask what it means for their taxes. By then the most useful planning window has already closed. The purchase still generates a deduction, but the owner has given up the chance to shape when and how that deduction lands, and whether it lines up with a year when it actually helps.
A practice is unusually well suited to this kind of planning. Equipment purchases tend to be large, somewhat predictable, and concentrated in a handful of categories: imaging, chairs and operatory units, sterilization, lab and diagnostic gear, and the technology that runs the front office. Because those purchases are sizable, the tax treatment is rarely trivial. A decision made deliberately in June often produces a better result than the same decision made under pressure in December.
Two tools do most of the work
Most equipment a practice buys can be deducted far faster than the old model of spreading the cost over five or seven years. Two provisions drive this. The first is the Section 179 expensing election, which lets a business deduct the full cost of qualifying equipment in the year it is placed in service, within annual limits. For tax years beginning in 2026, the maximum Section 179 deduction is $2,560,000, and that limit begins to phase out once total qualifying purchases exceed $4,090,000. You can review the current figures on the IRS depreciation page, Publication 946, How To Depreciate Property. For a practice, those ceilings are high enough that the limit is rarely the binding constraint. The planning questions are usually about timing and taxable income, not about hitting the cap.
The second tool is bonus depreciation. Under the One Big Beautiful Bill Act, 100% first-year bonus depreciation was made permanent for qualifying property acquired and placed in service after January 19, 2025. The IRS confirmed the details in Notice 2026-11. In plain terms, the option to write off the full cost of most equipment in year one is no longer scheduled to shrink the way it was under the prior phase-down. That removes a deadline that used to drive rushed year-end buying, and it gives owners more room to time purchases around the practice rather than around an expiring tax break.
The two provisions work together, and they are applied in a set order. Section 179 is elected first, then bonus depreciation applies to any remaining cost. For most practice purchases this is a detail your accountant handles, but the interaction matters when the practice is part of a partnership or when the owner wants to deduct some assets now and hold others back. This is one of the reasons the phrase “just write it all off” is usually too simple to be useful.
Why the bigger deduction is not always the better answer
It feels obvious that a faster, larger deduction is always better. In practice, it depends on the year. A deduction is most valuable when it offsets income that would otherwise be taxed at a high rate. If a practice has a strong year, accelerating a large equipment deduction into that year can be exactly right. If the practice had a soft year, or the owner expects a much stronger year ahead, deducting everything immediately can waste part of the benefit by erasing income that was barely going to be taxed anyway.
There is also the question of how the practice is organized and how the owner is paid. Owner compensation, distributions, and the entity structure all affect how an equipment deduction flows through to the owner’s personal return. A deduction that looks large at the practice level does not always translate into the tax saving the owner pictured. None of this argues against buying equipment. It argues for deciding the timing on purpose.
Bring the decision forward to mid-year
The reason we raise this in June is that mid-year is the point where you still have options. You can see roughly how the year is shaping up, you have time to schedule a purchase before December if accelerating the deduction makes sense, and you have time to wait until January if it does not. By late December, the calendar is making the decision for you, and a rushed purchase made mainly to capture a deduction is how practices end up with equipment they did not really need yet.
A short list of questions is usually enough to frame the conversation:
- How does this year’s practice income compare to last year, and what do you expect next year to look like?
- Is the equipment a true need now, or is the timing being driven mainly by the deduction?
- Would the deduction do more good this year or next, given your other income?
- How will financing affect cash flow, separate from the tax treatment?
- Does the purchase change anything about owner compensation or distributions for the year?
Notice that only two of those questions are strictly about taxes. The others are about the business. That is the point. Equipment decisions sit at the intersection of clinical need, cash flow, and tax, and the strongest outcomes come from looking at all three together rather than letting the tax tail wag the practice.
The advantage of current numbers
All of this is far easier when the practice’s books are current. If your financials are months behind, a mid-year planning conversation turns into guesswork, and the equipment decision gets made on instinct. When the books are close to real time, you can see where the year stands, model how a purchase changes the picture, and make the call with confidence. This is one of the quieter benefits of running accounting as an ongoing system rather than a once-a-year cleanup: the planning windows stay open because the information is always there when you need it.
If you are weighing an equipment purchase this year, the most useful step is to look at it before you sign, not after. Contact our office and we can walk through the timing, the deduction options, and how the purchase fits the rest of your year. We work with medical and dental practices across the region, and we would rather help you plan the purchase than explain the missed opportunity next April.
