Veterinary Practice Tax Planning in 2026: An Owner’s Playbook

• Tax planning is a year-round act, not an April one. Preparation records what happened; planning shapes it before year-end. Every lever below has to be set up during the year, and all of it is general education, not tax advice, so verify with your CPA.
• Equipment write-offs got dramatically better for 2026. Bonus depreciation is back to 100% and permanent for property placed in service after January 19, 2025, and Section 179 expensing tops out at $2,560,000, per the IRS. The timing of a big dental or imaging buy genuinely moves the bill.
• The 20% QBI deduction often disappears for vets. Veterinary medicine is a specified service trade or business, so for 2026 the deduction phases out between $201,750 and roughly $276,750 of taxable income for singles, and $403,500 to about $553,500 for joint filers, reaching $0 above that.
• S-corp pay is where audits start. There is no safe-harbor percentage; the 60/40 rule is a myth. Pay reasonable W-2 salary first, then distributions, or risk what happened in the Tax Court’s Veterinary Surgical Consultants case.
• Above $3 million in revenue, you’re running a real company. OwnerExchange is the one community built exclusively for owners of 3+ DVM practices doing $3 to $10M and up, where the room already knows which advisor to call before December, not after.

The most expensive tax mistake I ever watched an owner make cost nothing in penalties.

She’d had a good year. A strong four-doctor practice, a new digital dental suite installed in the fall, and a CPA who filed a clean, on-time return every spring. The problem surfaced in a hallway conversation in February, when she mentioned the equipment almost in passing. Her accountant hadn’t talked to her before December, so the purchase landed in a tax year where she got a fraction of the write-off she could have had. Nobody did anything wrong. The planning simply never happened.

That’s the quiet truth about practice taxes. The damage is rarely a mistake on the return. It’s the conversation that didn’t take place in time.

One thing before we go further. I’m a practice owner and a co-founder, not your accountant, and none of this is tax advice. Every figure here is “for 2026,” and every one of them deserves a “verify with your CPA” stamped next to it. This is also about running the financial side of a practice well, not about what your practice is worth or when to sell, which is a different conversation entirely.

What is veterinary practice tax planning, really?

Tax planning is the set of decisions you make during the year to lower the bill on purpose, before the return is ever filed. Preparation is the spring ritual of recording what already happened. Planning is the fall habit of shaping it.

The distinction matters because almost every lever that moves real money has to be pulled before December 31. A preparer can only report the timing you chose. A planner helps you choose it.

Here’s the honest version. Most owners I know have a perfectly competent person doing their taxes. What they’re missing isn’t accuracy. It’s a year-round advisor who calls in November and says, “before you sign for that CT unit, let’s talk about which year it lands in.”

The seven levers that actually move the bill

Let me put the whole playbook in one place before we walk through it. Treat this as a map of where the money is, not as instructions for your specific practice. Every one of these has rules and limits your CPA has to apply to your real numbers.

Tax lever	How it works (for 2026)	Who it fits
Bonus depreciation, Section 168(k)	100% first-year write-off, now permanent, on qualifying property placed in service after Jan 19, 2025	Any practice buying equipment, especially big dental, imaging, or surgical purchases
Section 179 expensing	Expense up to $2,560,000 of qualifying property; phases out above $4,090,000 of purchases	Practices wanting to choose which assets to expense vs. depreciate
S-corp reasonable compensation	Pay a defensible W-2 salary first, then take distributions, which aren’t subject to payroll tax	Profitable owners taxed as an S-corp who can document a reasonable wage
Retirement plan contributions	Defer up to $24,500 (401k/403b), plus catch-ups; up to $72,000 combined; far more with a DB plan	High-earning owners who want to shelter income and build wealth
Section 199A QBI deduction	Up to 20% of qualified business income, but it phases out for vets above income limits	Owners with taxable income below the SSTB phase-out thresholds
Accountable plan	Reimburse owner and staff business expenses tax-free instead of as taxable wages	Practices reimbursing mileage, home-office, or out-of-pocket costs
Hiring family	Pay a child or spouse a reasonable wage for real work done	Owners with family doing genuine, documentable work in the practice

Read down that table and the theme is obvious. None of this is exotic. It’s a handful of standard tools that reward setup and timing, and punish the scramble.

Equipment: the lever that just got much better

Start with the biggest piece of good news for 2026. The two equipment write-offs both got stronger, and the timing of a major purchase genuinely changes your tax bill.

Bonus depreciation under Section 168(k) is the headline. It returned to 100% and was made permanent for qualified property acquired and placed in service after January 19, 2025, per the 2025 tax law and IRS Notice 2026-11. That reverses the old phasedown, which had stepped down toward 40% in 2025 and was headed lower. In plain terms, a practice can generally write off the full cost of qualifying equipment in the year it goes into service.

Section 179 sits alongside it and gives you a dial. For 2026 it lets a practice expense up to $2,560,000 of qualifying property, with the benefit beginning to phase out once total purchases exceed $4,090,000, per IRS Revenue Procedure 2025-32. Where bonus depreciation is all-or-nothing on a class of assets, Section 179 lets you pick and choose, which is useful for fine-tuning taxable income.

The “placed in service” phrase is the part owners miss. The deduction follows the date the equipment is ready and available for use, not the date you ordered it or paid the deposit. A unit that ships in late December but isn’t installed and operational until January generally falls into the next tax year. That’s exactly the timing question worth a call before you sign.

Owner compensation: where the audits actually start

This is the lever owners most often get wrong, and it’s the one the IRS watches most closely. If your practice is taxed as an S-corporation, how you split your money between salary and distributions is a real decision with a clear rule.

The rule is reasonable compensation. You must pay yourself a reasonable W-2 salary for the work you actually do before taking distributions, per the IRS guidance for S-corporation officers. Distributions aren’t subject to FICA and payroll tax; wages are. That gap is the whole reason the rule exists.

Here’s the trap. There is no IRS safe-harbor percentage. The widely repeated “60/40 rule,” where you supposedly pay 60% as salary and take 40% as distributions, is a myth with no basis in the tax code. Setting an artificially low salary to dodge payroll tax is the classic audit trigger.

The case every veterinary owner should know is on point. In Veterinary Surgical Consultants (Tax Court, 2001), the court held that payments to a working owner were wages and could not be recharacterized as distributions to avoid employment tax. The lesson isn’t to avoid distributions. It’s to pay a defensible salary first and document how you landed on the number.

The goal isn’t the lowest possible salary. It’s a reasonable one you can defend without blinking. The owners who get this right usually have a room of peers who’ve already been through it. See who’s at the OwnerExchange table →

Retirement plans: the biggest legal shelter most owners underuse

If you want to move a large amount of income out of this year’s taxable pile and into your own future, retirement contributions are usually the most powerful legal tool you have. The 2026 limits are meaningful.

For 2026, per IRS Notice 2025-67, the employee deferral limit for a 401(k) or 403(b) is $24,500. The catch-up at age 50 and over is $8,000, and there’s a larger “super catch-up” of $11,250 for those ages 60 to 63. The combined Section 415(c) and SEP-IRA limit, which includes employer contributions, is $72,000.

For higher earners the ceiling goes much further. A defined benefit plan can allow an annual benefit funded toward $290,000, with a compensation cap of $360,000 used in the calculations. These plans are powerful but design-sensitive, so they want a CPA and a third-party administrator working together.

One rule change to flag with your advisor. Catch-up contributions must now go in as Roth, after-tax, for an owner whose prior-year FICA wages exceeded $150,000. That’s a coordination point, not a dealbreaker, but it’s the kind of detail that’s easier handled in advance than discovered at filing.

The QBI deduction: why it often vanishes for veterinarians

This is the lever where veterinary medicine draws a short straw, and where the planning is subtle. The 20% qualified business income deduction under Section 199A is permanent, but for vets it comes with a hard catch.

Veterinary medicine is a specified service trade or business in the field of health. That classification means the deduction phases out entirely once your taxable income climbs above set thresholds. Above the top of the range, the deduction for a veterinary owner is $0.

The 2026 numbers tell the story. The phase-out begins at $201,750 of taxable income for single filers and $403,500 for joint filers. The 2025 tax law widened the phase-in range to $75,000 for singles and $150,000 for joint filers, so the deduction completes its fade to zero at roughly $276,750 single and $553,500 joint. There’s also a new $400 minimum deduction if you have at least $1,000 of qualified business income.

The practical move is income management. Because the phase-out keys off taxable income, the very levers above, retirement contributions and equipment deductions, can sometimes pull income back under the threshold and partially restore QBI. That interaction is exactly the kind of thing a vet-aware advisor models in the fall, and exactly the kind of thing that’s invisible until someone runs the numbers for you.

The quiet levers: accountable plans and hiring family

The last two levers are smaller, but they’re clean and they’re often left on the table entirely. Both reward a little paperwork done in advance.

An accountable plan under Treasury Regulation 1.62-2 lets your practice reimburse business expenses, mileage, a home office, supplies bought out of pocket, as tax-free reimbursements rather than taxable wages. It has three requirements: a genuine business connection, proper substantiation, and the return of any excess advance. Set it up correctly and the money moves without payroll tax riding along.

Hiring family is the other one. Wages paid to a spouse or child have to be reasonable for real, documentable work, not a paper arrangement. Done properly, a child can earn income that’s sheltered up to the standard deduction, which can be an efficient way to fund a Roth or a college account from practice dollars. The watchword is “real work, reasonable pay, good records.”

One more piece of housekeeping that saves owners a penalty. The estimated-tax safe harbor, per IRS Publication 505, is generally paying in 90% of the current year’s tax or 100% of last year’s, but that jumps to 110% of last year’s tax if your prior-year adjusted gross income topped $150,000. For a profitable practice owner, that 110% figure is the one to set your quarterly payments against.

How to actually run the year

None of this works as a March activity. The thread running through every lever above is that the decision has to be made while the year is still open. So here’s how strong owners run it.

Have the year-end conversation in the fall. The single highest-value habit is a planning meeting with your CPA in October or November, before the equipment is installed and before the books close. That’s when timing is still yours to choose.

Decide equipment timing on purpose. If you’re buying a big-ticket unit, talk through which tax year “placed in service” lands in before you commit. The write-off is large enough to matter.

Pin down your salary and your estimates. Set a defensible S-corp salary and document it, and aim your quarterly payments at the right safe-harbor number so you’re not surprised in April.

Bring questions, not just receipts. The owners who pay the least tax aren’t the ones with the cleverest accountant. They’re the ones who ask, all year, “is there a smarter way to time this?” That’s general education talking, not tax advice, so take the specific moves to a CPA who knows your numbers.

Frequently asked questions

What are the most important veterinary practice tax levers for 2026?

For 2026, the levers most owners can actually move are equipment write-offs, owner compensation, and retirement contributions. Bonus depreciation is back to 100% and was made permanent for qualifying property placed in service after January 19, 2025, Section 179 lets a practice expense up to $2,560,000, and S-corp owners can shift earnings between salary and distributions within reason. Verify the specifics with your CPA, since the right mix depends on your income and entity.

Can a veterinary practice still use 100% bonus depreciation in 2026?

Yes. Under the 2025 tax law and IRS Notice 2026-11, bonus depreciation under Section 168(k) returned to 100% and was made permanent for qualified property acquired and placed in service after January 19, 2025. That reverses the old phasedown that had dropped to 40% in 2025. It means a practice can generally write off the full cost of qualifying equipment in the year it goes into service, though you should confirm eligibility with your accountant.

Do veterinarians qualify for the 20% QBI deduction in 2026?

Only below the income thresholds. The 20% qualified business income deduction is permanent, but veterinary medicine is a specified service trade or business in the field of health, so it phases out above set income levels. For 2026 the phase-out begins at $201,750 of taxable income for single filers and $403,500 for joint filers, completing near $276,750 single and $553,500 joint, above which the deduction is $0. Talk to your CPA about where your income lands.

How does S-corp reasonable compensation work for a veterinary practice owner?

You pay yourself a reasonable W-2 salary for the work you do before taking any distributions. There is no IRS safe-harbor percentage, so the common 60/40 rule is a myth, and paying an artificially low salary to avoid payroll tax is the classic audit trigger. The Tax Court in Veterinary Surgical Consultants confirmed wages cannot be recharacterized as distributions, so set the salary defensibly and document how you arrived at it.

What are the 2026 retirement contribution limits for a practice owner?

For 2026, the 401(k) or 403(b) employee deferral limit is $24,500, with an $8,000 catch-up at age 50 and a larger $11,250 super catch-up at ages 60 to 63. The combined Section 415(c) and SEP-IRA limit is $72,000. These let an owner shelter meaningful income, and a defined benefit plan can allow far more, so coordinate the plan design with your CPA and a third-party administrator.

Is veterinary practice tax planning the same as tax preparation?

No. Preparation records what already happened and files the return; planning shapes what happens before year-end so the bill is lower by design. The levers that matter most, equipment timing, entity and compensation structure, retirement funding, and an accountable plan, all have to be set up during the year, not in March. This is general education rather than tax advice, so plan the year with a qualified CPA who knows your numbers.
