Your state taxes the gloves. Six states also tax the crown. And most practices owe use tax on out-of-state orders without knowing the tax exists.
Your practice is the end consumer of almost everything it buys. That one sentence explains why there is no exemption certificate that makes your supply invoices tax free, and why the tax you pay on gloves and burs is not a mistake anyone is going to refund. What is worth your attention is the part that varies, because it varies more than almost any owner expects, and in six states it lands on the single largest thing you buy.
Here is how a CFO reads this. There are three separate questions, and owners tend to collapse them into one. What rate applies. What is actually taxable. And whether anyone collected it. The third one is where practices get letters.
In 45 states and the District of Columbia, a dental practice buying gloves, masks, burs, impression material and sterilization pouches pays sales tax on them. You are not reselling those items. You consume them delivering care, which makes you the retail purchaser, and retail purchasers pay. Ohio writes it into the statute by name: dentists are consumers of tangible personal property purchased in connection with their professional practices, per ORC 5739.01(D)(2). Kentucky, Nebraska, Mississippi and West Virginia all say some version of the same thing.
A handful of states break that pattern, and it is worth knowing whether you are in one. Three of them exempt your consumables broadly. Wyoming exempts all noncapitalized equipment and disposable supplies used in the direct care of a patient. Maryland exempts single-use dental supplies by name. Pennsylvania exempts anything intra-oral, disposable and consumed in treatment, which covers gloves, masks, disposable burs and composite, while still taxing reusable burs and sterilization pouches.
Four more split the supply closet item by item, and the splits are not intuitive. Minnesota exempts gloves and taxes masks. Massachusetts exempts the anesthetic and taxes the syringe that delivers it. Missouri taxes gloves and masks while exempting resin and amalgam. Vermont divides by purpose rather than by item, exempting the therapeutic and taxing the preventive and cosmetic. In those four, a single taxable-or-exempt answer for your whole supply order is the wrong shape of answer.
If you practice in one of those states and your supply invoices show tax on everything, someone is charging you tax you do not owe. That is worth a look at one invoice, not a project.
Most states treat a crown, a bridge or a denture as a prosthetic device and exempt it. That is the pattern owners assume is universal. It is not, and the six exceptions do not all get there the same way, which is worth understanding because the mechanism tells you where to look on your own invoices.
Four states wrote dental prostheses out of an exemption they otherwise grant. Ohio did it effective July 1, 2019: ORC 5739.01(HHH) now reads that prosthetic device "does not include dental prosthesis but does include corrective eyeglasses or contact lenses." Combined with ORC 5739.01(D)(2), which makes you the consumer, an Ohio practice owes sales or use tax on every lab crown and every denture, and nothing in the statute shifts that to the lab. Kentucky did the same thing effective January 1, 2023, excluding dental prosthesis from the definition in KRS 139.472. Hawaii excludes any dental device from its prosthetic definition outright. Arkansas does it twice over: dental prostheses are excluded from the prosthetic device definition by name, and the rule separately defines physician to exclude dentists, so a dentist's prescription cannot support the exemption even in principle.
Mississippi never granted one in the first place. Its regulation is blunter than the others: dentists are the users and consumers of all materials, supplies and equipment purchased for use in their practice, and therefore all sales made to dentists are retail transactions taxable at the regular rate, per Miss. Admin. Code 35.IV.12.03 section 100. There is no dental prosthesis carve-out to lose. Note the trap in the neighboring section: Mississippi does exempt raw materials that become an integral part of a manufactured product, but that exemption runs to licensed dental laboratories, not to you.
California is the sixth, and it is the most expensive version. It does not merely tax the crown. It makes the lab the retailer and applies tax to the entire lab charge, materials and fabrication labor together, however the invoice is itemized.
Run the arithmetic on that. A practice at $1.2 million in production with lab at 6% is buying roughly $72,000 of lab work a year. In Ohio at 5.75% state plus a typical 1.5% county, that is about $5,200 a year in tax on lab alone. It is not a crisis. It is also not nothing, and if your out-of-state lab has never charged it, it is a liability sitting on your books that nobody has recorded.
Every state with a sales tax has a matching use tax. It exists to close the obvious loophole. If you buy from an in-state vendor, the vendor collects. If you buy the identical item from an out-of-state vendor who is not registered in your state, nobody collects, and the obligation moves to you. You self-report it.
This is not obscure. Ohio requires a consumer's use tax account once annual liability exceeds $1,000 and takes the return on the UUT-1. Texas puts it on line 3 of the sales tax return, labeled taxable purchases. Pennsylvania puts it on line 6. North Dakota's own dental guideline tells dentists to put untaxed supply purchases on line four and remit.
The reason it goes unnoticed in dental is structural. Your supply and lab spend has moved online and out of state over the last decade, which means a growing share of your purchases arrive with no tax line on the invoice. An owner reads that as a discount. It is a deferral, and the person who owes it is you.
Two things make this manageable rather than alarming. First, it is arithmetic you can run once: pull a year of supply, lab and small equipment purchases, sort by whether tax was charged, and apply your rate to the untaxed column. Second, most states have a voluntary disclosure program that trades a limited lookback period for coming forward, which is a materially better outcome than being found. That is a conversation for your tax preparer, not a blog post, but you cannot start it if you do not know the exposure exists.
A box of gloves carries a few dollars of tax. A CBCT scanner carries a few thousand. On a $120,000 mill and scanner package, a 6% rate is $7,200, and if the vendor is out of state and did not collect, that is $7,200 of use tax due in the period you took delivery.
There is generally no exemption to reach for. Utah is the clean illustration. Utah's manufacturing exemption is limited to establishments inside SIC codes 2000 to 3999, and there is a separate machinery exemption for medical laboratories under NAICS 621511. A dental practice is neither. So the identical chairside mill can be exempt for a commercial dental laboratory down the street and taxable for the practice buying it, because the exemption follows what the buyer is, not what the machine does.
This is worth building into how you evaluate an equipment quote. A $120,000 quote from an out-of-state vendor is not cheaper than a $126,000 quote from an in-state vendor who collects. It is the same money with a filing obligation attached.
Everything above is the pattern. This is where you find yourself in it.
The table answers three questions per state: what the state rate is, whether your consumables are taxable, and whether your lab work is. Read your own row first, then read the note in the last column, because the note is usually where the exception lives. A state can look ordinary in the middle two columns and still carry a rule that changes what you owe.
Two things to keep in mind while you read it. Rates below are the state rate only, and almost every state layers county, city or transit taxes on top, so your combined rate is higher, sometimes by two points or more. And every cell traces to that state's own revenue department, statute or regulation, verified August 2026. Where a state has published nothing that answers the question, the cell says so rather than guessing, which is why you will see three cells marked as unconfirmed instead of filled in.

Rates and rules change. This table was built from state sources in August 2026 and is reviewed once a year. Two cells to watch: the District of Columbia moves from 6% to 7% on October 1, 2026, and Virginia repealed its dentist-specific regulation on September 28, 2024 without publishing a replacement.
If you practice in one of these, a sales tax table is the wrong document.
Hawaii and New Mexico tax your revenue, not just your purchases. Hawaii's General Excise Tax and New Mexico's Gross Receipts Tax both reach services, which means your dental production is inside the tax base. Hawaii runs 4% plus a county surcharge on dental services, though amounts received for Medicare, Medicaid and TRICARE covered services became exempt on January 1, 2026. New Mexico allows deductions for payments from managed care organizations and health insurers, which leaves your cash-pay and non-covered revenue exposed.
Washington has no sales tax on dental services and a Business and Occupation tax that does the same job. B&O applies to gross receipts under the Service and Other Activities classification at 1.5% under $1 million, 1.75% from $1 million to just under $5 million, and 2.1% at $5 million and above. There is no deduction for lab bills, supplies or payroll. A Washington owner reading only a sales tax table will conclude the state is friendly and be wrong by a wide margin.
Delaware has no sales tax and a gross receipts tax of 0.3983% on the practice's own revenue, with the first $100,000 a month exempt.
Montana, New Hampshire and Oregon are the genuine no-tax states for a practice's purchases. No sales tax, no use tax, nothing to file.
Three things, in order, and none of them take a project.
1. Find your state in the table and read one supply invoice against it. If you are in Pennsylvania, Maryland or Wyoming and you are being charged tax on disposables, you are overpaying. If you are in Ohio, Kentucky, Hawaii, Mississippi, Arkansas or California and your lab invoices carry no tax, you owe it.
2. Sort last year's supply, lab and equipment spend by whether tax was charged. That is a report your bookkeeper can run in an afternoon, but only if your books already separate supplies from lab fees. If those two sit commingled in one account, this exercise is guesswork.
Which is one more reason the separation earns its keep beyond benchmarking your supply cost percentage and your lab cost percentage. The same account structure that lets you read those two ratios is the structure that answers a state auditor.
3. Take the number to your tax preparer, not to the state. If there is exposure, voluntary disclosure is a better door than an assessment notice, and the difference between those two doors is usually just who spoke first.
One last framing. Sales and use tax is a compliance cost, not a strategic one. Nobody grows a practice by optimizing it. But it is the kind of item that sits quiet for years before it arrives as an assessment with interest already running, and preventing that costs you one afternoon with your own invoices.
P.S. Reciprocity Accounting codes supplies, lab and equipment to separate accounts every month, so the question of what you were charged tax on has an answer instead of an estimate. See how we can help your practice.
In 45 states and the District of Columbia, yes. Your practice consumes gloves, masks, burs and impression material delivering care rather than reselling them, which makes you the retail purchaser. Wyoming, Maryland and Pennsylvania are the meaningful exceptions, and Massachusetts, Minnesota, Missouri and Vermont exempt some items while taxing others.
Not in any state that has a general sales tax. Hawaii and New Mexico reach dental revenue through a General Excise Tax and a Gross Receipts Tax instead, Washington reaches it through the Business and Occupation tax, and Delaware through a gross receipts tax. Those are different taxes, not sales tax, and they are the reason a practice in those four states cannot rely on a sales tax answer.
In most states no, because they qualify as prosthetic devices. In six states the answer is yes. Ohio, Kentucky, Hawaii and Arkansas each wrote dental prostheses out of the prosthetic exemption, or defined the prescribing practitioner in a way that excludes dentists, or both. Mississippi simply treats dentists as consumers of everything they buy, so there was never an exemption to lose. California taxes the entire lab invoice, materials and labor together, because it makes the lab the retailer.
Use tax is the companion to sales tax. When you buy a taxable item from an out-of-state vendor who does not collect your state's tax, you owe the same amount directly to your state and report it yourself, usually on a line of your sales and use tax return. If your practice orders supplies, lab work or equipment online from out-of-state vendors and those invoices show no tax, use tax is almost certainly due and almost certainly unrecorded.
Not for consumables in most states, because exemption certificates are built for resale and you are not reselling gloves. Where an exemption exists it usually attaches to prosthetic devices rather than to you as a dentist, and several states condition it on a prescription or work order being in hand. Nebraska requires all three of a prescription, single-patient use, and a Medicaid-eligible device type.
Yes in every state with a sales tax, and there is generally no exemption available to a practice. Utah is the clearest illustration: its manufacturing exemption is limited to manufacturing establishments and medical laboratories, so a commercial dental lab can claim it on a mill and the practice next door cannot claim it on the same machine. If the vendor is out of state and did not collect, the amount becomes use tax due in the period you took delivery.
