Can All-on-X Be Tax Deductible? How It Works, Plus a Calculator
October 13, 2026Dr. Conner Noland, DDSHeber Springs, AR
I am a dentist, not a tax advisor, and nothing on this page is tax advice. The numbers below are estimates only. Please speak with your accountant or tax advisor before making any decision based on them.
Not everybody thinks to ask this one, but it's worth knowing before you write the check. Full arch implants cost real money. Depending on how you pay and when, some of it can come back to you at tax time. Not always, and usually not as much as people are hoping, but often enough that I bring it up. Below is how it works, and a calculator so you can get a rough idea of your own situation before you talk to your accountant.
1. The medical expense deduction
The IRS lets you deduct medical and dental bills you paid yourself and didn't get reimbursed for. Two catches. Only the part above 7.5 percent of your adjusted gross income counts, and you have to itemize instead of taking the standard deduction. Here's what each of those means for a full arch case.
Does All-on-X count?
Dental work is on the IRS list in Publication 502. Extractions, dentures, treating disease, all of it. When I take out failing teeth and replace them with implants, I'm treating infection, bone loss, and teeth that can't be saved. That's medical treatment, not cosmetics. Cosmetic work doesn't qualify, so if your accountant ever asks, the answer is in your chart. Infected teeth, bone loss, teeth that couldn't be restored. We document all of that anyway.
The 7.5 percent floor
Say your household income is $80,000. The first $6,000 of medical bills that year don't count for anything. Everything past that can. That's why a $200 filling never moves the needle and a $23,000 to $53,000 implant case does. You clear the floor in one shot.
You have to itemize
For 2026 the standard deduction is $16,100 if you're single, $24,150 for head of household, and $32,200 for married filing jointly. Itemizing only helps if your deductions add up to more than that. That's your medical above the floor, plus mortgage interest, state and local taxes up to the cap, and what you give to church or charity. A lot of my patients haven't itemized in years. A full arch case is often the thing that puts them back over the line.
Made up example. A married couple makes $90,000 and pays $50,000 for a double arch in 2026. Their floor is $6,750, so $43,250 of the treatment counts. They have $12,000 in other deductions, so they're at $55,250 itemized. That beats the $32,200 standard deduction by $23,050. In the 22 percent bracket, that's about $5,070 back. Your numbers will be different. That's the whole point of talking to your accountant.
2. HSA and FSA money
If you have a Health Savings Account or a Flexible Spending Account through your job, implants are generally an eligible expense. That money went in before taxes, so every dollar you spend from one of those accounts saves you whatever your tax rate is. No floor, no itemizing.
HSA. You can put in $4,400 for yourself or $8,750 for a family in 2026, and you can spend money you've been saving in there for years. You need a high deductible health plan to contribute.
FSA. The 2026 limit is $3,400, and you lose what you don't use by the end of the year. That's what makes it a good fit for something planned like surgery. Pick your amount at open enrollment and the whole thing is available to you January 1.
You can't count the same dollar twice. Money from an HSA or FSA is already tax free, so it doesn't also go toward the itemized deduction.
3. When you pay matters
Because of the floor and the itemizing rule, the timing of your payment can matter as much as the amount.
Pay it in one year. If half lands in December and half in January, you might not clear the floor either year. All of it in one year is one big deduction.
Financing counts the day we get paid. If you go through Proceed Finance, LendingClub, or Cherry, the lender pays us in full up front. That's generally the year it counts, even though you're making payments after. Same with a credit card. The charge date is the payment date.
The whole household counts. Your spouse's and kids' medical bills in the same year add to yours. If somebody in the family has a surgery coming or an expensive prescription year, putting it all in the same year helps.
The drive counts. People come to Heber Springs from all over Arkansas and from out of state. Mileage to get medical care is deductible, and so is lodging up to a nightly limit. Write it down.
If you're 65 or older. There's a new extra deduction for seniors through 2028 with income limits. It changes the itemize or don't itemize math, so ask your preparer about it specifically.
Run your own numbers
Put in your best guesses. The calculator uses the 2026 standard deduction and the 7.5 percent floor, and you pick your own tax rate. It doesn't know about credits, phase outs, alternative minimum tax, or your state's rules. It's a starting point for a conversation with your accountant, not a tax return.
All-on-X Tax Benefit Estimator
Rough estimates. Take these numbers to your accountant.
Most All-on-X cases fall between $23,000 and $53,000 depending on one arch or two and what your case requires. Your consultation gives you the real number.
Line 11 on last year's Form 1040 is a fine starting guess.
2026 standard deduction: $16,100 / $24,150 / $32,200.
Mortgage interest, state and local taxes up to the cap, charitable gifts. Enter 0 if unsure.
The rate on your last dollar of income, not your average rate.
Pre-tax dollars save your marginal rate with no floor, but they are removed from the deductible amount below.
Arkansas's top rate is 3.9 percent. Many states follow the federal medical deduction. Set to 0 to ignore.
7.5 percent of AGI (the floor)$6,750
Treatment paid out of pocket, after HSA/FSA$50,000
Medical amount above the floor$43,250
Total itemized deductions$55,250
Standard deduction you would otherwise take$32,200
Extra deduction created by the treatment$23,050
Estimated federal savings from itemizing$5,071
Estimated federal savings from HSA/FSA dollars$0
Estimated state savings (rough)$899
Estimated total tax benefit Effective cost after estimated benefit: $44,030$5,970
This estimator is a simplified illustration for educational purposes. It assumes the treatment is a qualifying medical expense, that you were not reimbursed by insurance, and that all payments fall in one tax year. It ignores credits, phase-outs, the alternative minimum tax, the senior deduction, and state-specific rules. It is not tax advice. Confirm every number with your accountant or tax advisor before relying on it.
What this won't do
I'd rather you hear the limits from me now than from your accountant in April.
It won't make All-on-X cheap. For most people the benefit is a few thousand dollars. That's worth having, but it's not a discount.
If you make a lot relative to the cost and don't have many other deductions, the floor and the standard deduction eat most of it. The calculator will show you when that's happening.
It's not a substitute for a professional. Your accountant knows about credits, phase outs, the senior deduction, and Arkansas rules. This page doesn't.
None of this decides whether you should do the treatment. That's about your mouth, your health, and how you want to eat for the next 20 years. The tax part is housekeeping after you've decided.
How my office helps
You shouldn't have to translate dentistry into accountant language yourself. Here's what we do for any patient who asks. No charge.
Itemized paid in full statement. Date paid, procedure codes, amounts, the way accountants want to see it. If you financed, it shows the date the lender paid us.
Letter of medical necessity. If your accountant wants it, I'll write a letter saying what we treated and why. Infected teeth, bone loss, teeth that couldn't be saved. It comes straight from your chart.
Scheduling around your tax year. If your accountant says December is better than January, or the other way around, tell us. We'll set the surgery and payment dates to match.
HSA and FSA receipts. We take the cards and give you the receipts those plans require.
We'll talk to your accountant. Sign a release and we'll get them whatever they need directly. Without the release, your information stays with you. Your call.
Travel paperwork. If you're driving in, we'll confirm your appointment dates in writing so your mileage and hotel records are easy to back up.
What we won't do is tell you what to deduct. That's your accountant's job. Ours is to get them what they need from us quickly.
What I'd do
Run the calculator with rough numbers so you have a ballpark and a few questions.
Ask your accountant three things. Should I itemize if I do this? Should I pay it all in one calendar year, and which year? Should some of it go through an HSA or FSA?
If an FSA makes sense, line up your election and your surgery date in the same plan year. We can work with that.
Keep your receipts, your financing paperwork, and your mileage. Ask us for the itemized statement.
If you'd rather talk about the treatment first, that's what the consultation is for. I'll show you the real number and every way to make it work. And when you do sit down with your accountant, tell them what we were treating. That usually answers their first question.
