Your own medical expenses as a sole proprietor generally do not belong among your Schedule C medical expenses. The IRS treats the owner’s health costs as personal, and the Schedule C instructions specifically direct you to claim personal health insurance elsewhere on your return. Employee medical costs are the exception and do belong on Schedule C. Everything else — your premiums, your copays, your prescriptions — has a different home on the 1040.
Why the Owner’s Medical Costs Fail the Schedule C Test
Schedule C reports the income and expenses of running a sole proprietorship or single-member LLC. To deduct a cost there, it has to be “ordinary and necessary” to operating the business. Your personal insurance premiums and doctor visits keep you healthy; in the IRS’s view, they don’t keep the business running.1Internal Revenue Service. 2025 Instructions for Schedule C (Form 1040)
The Schedule C instructions say this directly. Contributions to your own accident and health plan don’t go on Line 14. Instead, “you may be able to deduct on Schedule 1 (Form 1040), line 17, the amount you paid for health insurance on behalf of yourself, your spouse, and dependents.”1Internal Revenue Service. 2025 Instructions for Schedule C (Form 1040) That’s the self-employed health insurance deduction, and it’s where most of your actual tax savings live.
Where Your Own Premiums Actually Go
The self-employed health insurance deduction subtracts qualifying premiums directly from gross income, above the line, before you reach your adjusted gross income. Because it lowers AGI rather than acting as an itemized deduction, it can also improve your eligibility for other AGI-sensitive benefits like education credits, the child tax credit, and IRA deductibility.
What Premiums Qualify
Medical, dental, and vision premiums for you, your spouse, your dependents, and your children under 27 all qualify, whether or not those children are your dependents for tax purposes.2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Medicare Part B, Part D, Medigap supplemental premiums, and qualified long-term care premiums count too, with long-term care subject to age-based annual caps that apply per person.3Internal Revenue Service. Instructions for Form 7206
The Eligibility Trap
Two rules can shrink this deduction. The plan must be established under your business, and you cannot claim the deduction for any month in which you were eligible to participate in a subsidized health plan maintained by any employer, including your spouse’s employer. The IRS applies this month by month. If your spouse’s employer coverage started in April, you claim the deduction only for January through March.2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses
Mere eligibility disqualifies you. Enrollment isn’t required. If your spouse’s employer offers a family plan you could join but you turn it down, those months are still off the table.3Internal Revenue Service. Instructions for Form 7206
The Earned Income Ceiling
The deduction cannot exceed your earned income from the business that established the plan. Earned income here means Schedule C net profit reduced by the deductible portion of self-employment tax and any SEP, SIMPLE, or qualified plan contributions tied to that business.2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses A business loss means no deduction at all for the year. Premiums above the limit aren’t wasted; they can move over to Schedule A as regular medical expenses.
How to Claim It
Calculate the deduction on Form 7206, which walks through the earned income limit and produces the deductible amount. That figure goes on Schedule 1 (Form 1040), line 17.3Internal Revenue Service. Instructions for Form 7206 You don’t have to itemize to claim it. The deduction is available whether you take the standard deduction or itemize on Schedule A.
Out-of-Pocket Costs and Schedule A
Copays, prescriptions, lab fees, and medical equipment you pay for yourself are personal costs. The only path to a deduction is itemizing on Schedule A, and the math rarely cooperates.
The 7.5% AGI Floor
You can only deduct qualified medical expenses to the extent they exceed 7.5% of your AGI.4Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses At an $80,000 AGI, the first $6,000 of medical spending produces nothing. Spend $9,000, and only $3,000 counts.
That $3,000 then has to combine with your other itemized deductions — state and local taxes, mortgage interest, charitable contributions — to beat the standard deduction. For 2026 the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.5Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments from the One Big Beautiful Bill Most self-employed filers will never clear that bar on medical spending alone.
What Counts
Qualified expenses are anything paid for diagnosis, treatment, prevention of disease, or care affecting a structure or function of the body.6Office of the Law Revision Counsel. 26 USC 213 – Medical, Dental, Etc., Expenses Doctor and dentist payments, prescription drugs, insulin, eyeglasses, contact lenses, hearing aids, and medically necessary equipment all qualify. Transportation for medical care is deductible at 20.5 cents per mile for 2026.7Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile, Up 2.5 Cents
Over-the-counter drugs other than insulin need a doctor’s prescription to qualify.4Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses General supplements, vitamins, and cosmetic weight-loss programs don’t. Cosmetic surgery is out unless it corrects a congenital abnormality, disfiguring injury, or disease.
No double-dipping. Premiums already claimed through the self-employed health insurance deduction can’t also appear on Schedule A, and expenses reimbursed by insurance or paid from an HSA distribution are excluded.2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses
The HSA Is Usually the Better Tool
Because the 7.5% floor makes Schedule A impractical for most people, a Health Savings Account is often the smarter route for out-of-pocket costs. HSA contributions are deductible above the line on Schedule 1, withdrawals for qualified medical expenses are tax-free, and there’s no percentage-of-income floor to clear.8Internal Revenue Service. Instructions for Form 8889 Over-the-counter medicines qualify as HSA-eligible expenses without a prescription, which they don’t on Schedule A.
You need a qualifying high-deductible health plan to contribute. For 2026, an HDHP has a minimum annual deductible of $1,700 for self-only coverage or $3,400 for family coverage, and maximum out-of-pocket costs of $8,500 (self-only) or $17,000 (family).9Internal Revenue Service. 2026 Inflation Adjusted Items for Health Savings Accounts (HSAs) The 2026 contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, with an extra $1,000 catch-up if you’re 55 or older.10Internal Revenue Service. Expanded Availability of Health Savings Accounts Under the One, Big, Beautiful Bill Act (OBBBA) – Notice 2026-5 Report contributions on Form 8889; the deduction flows to Schedule 1, line 13.
One recent change matters here. The One, Big, Beautiful Bill Act expanded HSA eligibility to treat bronze and catastrophic plans (whether purchased through the marketplace or not) as HSA-compatible, even if they don’t meet the traditional HDHP definition. The law also lets HSA holders in certain direct primary care arrangements contribute to an HSA and use HSA funds tax-free for those periodic fees.11Internal Revenue Service. Treasury, IRS Provide Guidance on New Tax Benefits for Health Savings Account Participants Under the One Big Beautiful Bill If you’ve been on a bronze plan and assumed you couldn’t open an HSA, that’s worth another look.
Employee Medical Costs Do Go on Schedule C
Here’s where medical spending genuinely lands on Schedule C. If your business has W-2 employees, premiums you pay for their health coverage and the medical benefits you provide are legitimate business expenses. They go on Line 14 (Employee benefit programs) and reduce business income dollar-for-dollar, with no AGI threshold and no earned income cap.1Internal Revenue Service. 2025 Instructions for Schedule C (Form 1040)
A formal group health plan lets you deduct 100% of premiums paid on behalf of employees, and those premiums are generally excluded from employee taxable income. If a group plan doesn’t fit, a Qualified Small Employer Health Reimbursement Arrangement (QSEHRA) lets you reimburse employees for individual health insurance premiums and medical expenses. To offer one you must have fewer than 50 full-time employees and no group health plan.12Internal Revenue Service. Qualified Small Employer Health Reimbursement Arrangements Notice 2017-67 For 2026, QSEHRA reimbursements are capped at $6,450 annually for self-only coverage and $13,100 for family coverage. Amounts reimbursed are deductible on Schedule C and generally tax-free to the employee.
The critical limit: these rules apply to employees, not to the owner. As the sole proprietor, you still handle your own costs through the self-employed health insurance deduction, an HSA, or Schedule A.
The Spouse-Employee Route
One planning technique involves hiring your spouse as a bona fide W-2 employee and establishing a Section 105 health reimbursement arrangement. Your spouse, as an employee, receives family health coverage through the business, which covers both of them and you as a family member. The business then reimburses qualifying medical expenses (copays, deductibles, prescriptions, dental work) through the Section 105 plan, and those reimbursements are deductible on Schedule C, Line 14.
Done properly, this converts the owner’s out-of-pocket medical costs into deductible business expenses, sidestepping both the earned income cap on the self-employed health insurance deduction and the 7.5% AGI floor on Schedule A. Done sloppily, it invites scrutiny. Your spouse must perform real work, the compensation must be reasonable for that work, and the plan must be documented in writing. Reimbursing more than the work would justify is a red flag. Set this up with a tax professional; the IRS has seen every version of the arrangement.
If You Buy Coverage Through the Marketplace
Self-employed filers who receive a premium tax credit face a circular calculation. The self-employed health insurance deduction lowers AGI, a lower AGI raises the premium tax credit, a larger credit reduces the premiums available for the deduction, and the AGI shifts again.13Internal Revenue Service. Revenue Procedure 2014-41 – Guidance for Self-Employed Health Insurance Deduction and Premium Tax Credit
The IRS provides both an iterative method and a simplified method to resolve the loop, both described in Publication 974. Using them is optional as long as your combined deduction and credit don’t exceed the premiums you actually paid.14Internal Revenue Service. Publication 974 (2025), Premium Tax Credit (PTC) Tax software usually handles this automatically. If you work with a preparer, confirm they’ve accounted for the interaction. Getting it wrong means either leaving money behind or triggering a reconciliation notice.
