Section 213 Medical Expense Deduction: 2026 Guide for Tax Pros

Section 213 Medical Expense Deduction: 2026 Guide for Tax Pros

The Section 213 medical expense deduction is one of the most misunderstood write-offs on the return. For 2026, it lets your client deduct unreimbursed medical costs above 7.5% of adjusted gross income. However, they must itemize on Schedule A. Most filers never clear both hurdles. Yet for the clients who do, the planning fees are real. Here is how to spot them fast.

Key Takeaways

• Only unreimbursed medical costs above 7.5% of AGI are deductible under IRC Section 213(a).
• Your client must itemize on Schedule A. Otherwise, the deduction is worth zero.
• For 2026, standard deduction amounts are $16,100 single and $32,200 married filing jointly.
• Expenses paid from an HSA, FSA, or HRA never qualify. That is double-dipping.
• Bunching elective procedures into one year is the highest-value planning move here.

What Is the Section 213 Medical Expense Deduction?

The statute is short but dense. IRC Section 213(a) permits a deduction for expenses paid during the taxable year for medical care of the taxpayer, a spouse, or a dependent. Those expenses must not be compensated for by insurance or otherwise. Furthermore, only the portion exceeding 7.5% of adjusted gross income is deductible. That floor is permanent law now. As a result, the old 10% threshold discussion is obsolete.

This matters for your practice. Many solo practitioners skip the medical section entirely because so few clients qualify. However, that habit costs you. The clients who do qualify often have complex situations. Those situations justify real proactive tax strategy engagements rather than a flat prep fee.

How the Code Defines Medical Care

Section 213(d)(1) defines medical care as amounts paid for the diagnosis, cure, mitigation, treatment, or prevention of disease. It also covers amounts paid for the purpose of affecting any structure or function of the body. In plain English, if a cost treats a real medical condition, it likely qualifies. General wellness spending does not.

The definition also reaches transportation primarily for and essential to medical care. Moreover, it includes qualified long-term care services and certain insurance premiums. The IRS expands on all of this in IRS Publication 502 on medical and dental expenses. Keep that publication open during any client review.

Who Counts as a Dependent Here

This is where practitioners leave money behind. For Section 213 purposes, the dependency test is relaxed. A person can qualify even if they fail the gross income test. They can also qualify if they filed a joint return. So an adult child or an aging parent may still count.

Think about your clients supporting elderly parents. If your client pays the nursing home bill, those payments may be deductible on your client’s return. Ask the question during every intake. Most preparers never do.

How Does the Two-Gate Test Work in 2026?

Most articles cover one gate. Practitioners need both. Gate 1 asks whether unreimbursed medical costs exceed 7.5% of AGI. Gate 2 asks whether total itemized deductions beat the standard deduction. A client can clear Gate 1 and still get nothing.

2026 Standard Deduction Amounts

Filing Status	2026 Standard Deduction	Prior Year (2025)
Single	$16,100	$15,750
Married Filing Jointly	$32,200	$31,500
Head of Household	$24,150	$23,625

Verify current amounts at the IRS inflation adjustment announcement for 2026. Additional standard deduction amounts apply for clients age 65 or older. Those add-ons raise Gate 2 even higher for retirees.

A Full Worked Example

Take a married couple with AGI of $90,000. They paid $14,000 in unreimbursed medical bills. First, compute the floor: $90,000 times 0.075 equals $6,750. Next, subtract. The deductible medical amount is $7,250. Gate 1 is cleared.

Now test Gate 2. Suppose they also have $9,000 of mortgage interest and $10,000 of state and local taxes. Their total itemized deductions reach $26,250. However, the 2026 married filing jointly standard deduction is $32,200. Therefore they take the standard deduction. The medical expenses produce zero benefit.

Change one variable. Suppose the couple prepaid a $12,000 dental implant series in December. Medical expenses now total $26,000. The deductible portion becomes $19,250. Total itemizing reaches $38,250. Consequently, they itemize and gain $6,050 over the standard deduction. At a 22% marginal rate, that is roughly $1,331 in real savings.

Which Medical Expenses Are Deductible?

The list is broader than most clients think. Furthermore, several categories go unclaimed every year. Medical mileage is the biggest miss. Capital home improvements for medical necessity run a close second.

Deductible Versus Not Deductible

Deductible	Not Deductible
Doctors, dentists, surgeons, chiropractors	Cosmetic surgery (with exceptions)
Prescription drugs and insulin	Most over-the-counter drugs
Eyeglasses, contacts, hearing aids	Toiletries and toothpaste
Wheelchairs, crutches, guide dogs	Gym memberships without a diagnosis
Addiction and smoking-cessation programs	Funeral and burial costs
After-tax medical and dental premiums	Pre-tax cafeteria plan premiums
Medical mileage, parking, and tolls	Commuting to work
Nursing home care for medical reasons	HSA or FSA reimbursed costs

Travel, Lodging, and Home Modifications

Clients who travel for treatment often keep no records. Mileage driven for medical care is deductible at the IRS standard medical rate. Parking and tolls are added on top. Alternatively, clients may deduct actual gas and oil costs. Check the current rate in the IRS topic page on medical and dental expenses.

Lodging away from home for medical care is capped per night, per person. No lavish or recreational element may be involved. Meals during that travel are generally not deductible.

Home modifications deserve their own conversation. Ramps, widened doorways, stair lifts, and grab bars can qualify. However, the deduction is limited. You deduct the cost only to the extent it exceeds any increase in the property’s value. Get an appraisal opinion before you claim a large number.

What Are the Special Rules Under Section 213?

Citing subsections builds credibility with clients and with the IRS. Moreover, it separates you from the preparer down the street. Here are the four rules you should know cold.

Prescription Drugs and Cosmetic Surgery

Section 213(b) limits drug deductions to prescribed drugs and insulin. Over-the-counter medicine does not count, even when a doctor suggests it. Insulin is the notable exception. It qualifies without a prescription.

Section 213(d)(9) excludes cosmetic surgery. However, the exclusion drops away when the procedure corrects a deformity from a congenital abnormality, a personal injury, or a disfiguring disease. Reconstructive surgery after an accident therefore qualifies. Elective aesthetic work does not.

Divorced Parents and Long-Term Care

Under the divorced-parent rule, each parent may deduct the child’s medical expenses they actually paid. Dependency status does not control the outcome. Consequently, the non-custodial parent still gets a deduction for bills they covered.

Section 213(d)(10) caps eligible long-term care premiums by age. These caps adjust for inflation each year. Verify the current-year amounts at the official IRS Publication 502 page before you file.

Age at Year End	Treatment of Premium
40 or under	Lowest annual cap applies
41 to 50	Second-tier cap applies
51 to 60	Third-tier cap applies
61 to 70	Fourth-tier cap applies
Over 70	Highest annual cap applies

Only qualified long-term care contracts count. Hybrid life and long-term care policies require careful review. Consult the statutory text at Cornell Law School’s version of 26 U.S. Code 213 when a policy looks unusual.

Why Do HSA and FSA Accounts Kill the Deduction?

 

 

This is the most common error on amended returns. A client pays a $4,000 hospital bill with HSA funds. Then they hand you the receipt. That expense is fully reimbursed. Therefore it never enters the Section 213 medical expense deduction calculation.

The Strategic Trade-Off

Here is where advisory value shows up. A client with a large HSA balance can choose. They may pay medical bills out of pocket and let the HSA grow tax-free. Alternatively, they may reimburse themselves immediately.

Paying out of pocket preserves the Section 213 deduction. It also keeps HSA dollars compounding. However, it requires cash flow. Model both paths before you advise. This is exactly the kind of scenario modeling that entity-aware tax planning software handles across the full client portfolio. Uncle Kam’s MERNA framework sequences these decisions instead of treating them one at a time.

The Premium Deductibility Matrix

Premium Type	Deductible Under 213?	Where Claimed
Employer pre-tax (cafeteria plan)	No	Already excluded from wages
Employer after-tax	Yes	Schedule A
Marketplace or COBRA	Yes, net of credits	Schedule A
Medicare Parts B and D	Yes	Schedule A
Qualified long-term care	Yes, up to age cap	Schedule A
Self-employed health premiums	Not under 213	Above the line, Section 162(l)

That last row is critical. Self-employed clients get an above-the-line deduction. It bypasses both gates entirely. Never bury those premiums on Schedule A. Instead, review the structure with your self-employed and 1099 contractor clients each year.

How Can Bunching Unlock the Section 213 Medical Expense Deduction?

Spread across two years, $20,000 of medical spending may produce nothing. Concentrated into one year, the same $20,000 can produce a real deduction. This is the single most valuable planning move for the Section 213 medical expense deduction.

The Timing Rule That Governs Everything

Expenses count in the year paid, not the year billed. That cash-basis rule is your lever. A December 28 payment lands in 2026. A January 3 payment lands in 2027. Credit card charges count when charged, not when the card is paid off.

Therefore you can shift outcomes with a phone call. Tell the client to prepay the orthodontist in December. Or tell them to delay the elective procedure until January. Either move can be worth thousands. For firms in the Fayetteville area weighing entity and planning tools, this timing lever pairs naturally with broader structure reviews.

Which Clients to Screen First

• Retirees with high prescription costs and Medicare premiums.
• Families paying for a parent in assisted living.
• Clients facing major dental or orthodontic work.
• Anyone with a low-income year and a large medical event.
• Clients already itemizing due to mortgage interest and SALT.

A low-AGI year is the hidden gem. The 7.5% floor drops with AGI. So a business owner with a down year may suddenly clear Gate 1 easily. Pair that insight with smart entity structuring decisions and the planning fee justifies itself.

How Do You Claim It on Schedule A?

The mechanics are simple. The judgment is not. Follow these steps in order for every qualifying client.

Six Steps to File Correctly

1. Total all unreimbursed medical expenses paid during 2026.
2. Subtract every HSA, FSA, HRA, and insurance reimbursement.
3. Multiply AGI by 0.075 to find the floor.
4. Subtract the floor from net expenses.
5. Add the result to other itemized deductions on Schedule A.
6. Compare that total to the 2026 standard deduction, then choose.

Substantiation and Recordkeeping

Medical deductions draw attention when they are large. Consequently, documentation matters. Keep itemized provider statements, not just credit card summaries. Retain explanation-of-benefits forms showing what insurance paid. Maintain a contemporaneous mileage log with dates, destinations, and purpose.

For home modifications, keep the contractor invoice and a value opinion. For long-term care, keep the policy declaration page. Review the official Schedule A instructions on IRS.gov each filing season for line changes.

Record retention should run at least three years from the filing date. Six years is safer when large amounts are involved. Store documents digitally alongside your tax preparation and filing workflow so support is instantly retrievable.

Uncle Kam in Action: The Retiree Nobody Screened

Client Snapshot: A married couple, both age 68, retired from a family manufacturing business. They came to a solo practitioner in the Uncle Kam network after a decade with a national chain preparer.

Financial Profile: Combined AGI of $118,000 from Social Security, pension income, and required minimum distributions. They also held a modest rental duplex.

The Challenge: The husband needed knee replacement surgery. The wife carried a qualified long-term care policy. They also paid roughly $14,000 annually toward the wife’s mother’s assisted living costs. Their prior preparer never asked about any of it. They took the standard deduction three years running.

The Uncle Kam Solution: The advisor ran the two-gate test in a single planning session. First, she confirmed the mother-in-law qualified as a dependent for Section 213 purposes despite failing the gross income test. Next, she recommended scheduling the knee surgery for November rather than the following February. Then she instructed the couple to prepay the surgical center deposit and six months of assisted living before December 31. Finally, she captured Medicare Part B and Part D premiums plus the age-capped long-term care premium.

The Results: Total unreimbursed medical expenses reached $41,200. The 7.5% floor was $8,850. Therefore the deductible medical amount hit $32,350. Combined with property taxes and charitable gifts, itemized deductions reached $47,900. That beat their standard deduction by a wide margin.

• Tax Savings: $4,180 in federal tax reduced for the year.
• Investment: $1,500 planning engagement fee.
• First-Year ROI: Roughly 2.8 times the fee paid.

The couple then referred two friends in similar situations. See more outcomes like this on the Uncle Kam client results page. The lesson is simple. One screening question converted a $400 prep client into a recurring advisory relationship.

Solo practitioners often serve exactly this profile. If you work with high-net-worth individuals and retirees, medical timing belongs in your annual review checklist. Firms offering ongoing tax advisory services capture this value every year, not just once.

Frequently Asked Questions

Are dental expenses covered by the Section 213 medical expense deduction?

Yes. Dental care qualifies as medical care under Section 213(d). Cleanings, fillings, crowns, extractions, orthodontics, and dentures all count. However, purely cosmetic dentistry such as teeth whitening does not. The same 7.5% AGI floor applies to dental costs.

Can a client deduct mileage driven to the doctor?

Yes. Transportation primarily for and essential to medical care qualifies. Clients may use the IRS standard medical mileage rate or actual gas and oil costs. Parking fees and tolls are deductible either way. Always require a written mileage log for support.

Do Medicare premiums qualify under Section 213?

Yes. Medicare Part B, Part C, and Part D premiums are deductible medical expenses. Part A premiums qualify only when the client voluntarily enrolls and pays. For self-employed clients, Medicare premiums may instead be claimed above the line under Section 162(l).

Can both divorced parents deduct a child’s medical bills?

Yes, each parent deducts what they actually paid. Section 213(d)(5) treats the child as a dependent of both parents for this purpose. Dependency claiming rights do not control. Therefore the non-custodial parent still gets a deduction for bills they covered directly.

Are nursing home costs fully deductible?

It depends on the reason for the stay. If the primary reason is medical care, the entire cost including meals and lodging qualifies. However, if the stay is primarily personal, only the medical portion counts. Get a written statement from the facility allocating costs.

How long does implementing this planning take?

A first screening takes about twenty minutes. Building the bunching plan takes another hour. Most solo practitioners bill $750 to $2,500 for the engagement. Consequently, the return on your time is strong when you screen systematically rather than reactively.

What if a client already used an HSA for the expense?

That expense is off the table permanently. HSA, FSA, and HRA distributions are already tax-free. Deducting the same cost again is double-dipping. Review distribution records before totaling expenses. Otherwise you risk an accuracy-related penalty on the client’s return.
