The 'Section 105 HRA' Medical Engine: How Freelancers Write Off $12,000 in Healthcare Costs (and Slay the 7.5% AGI Tax Trap)

The $10,000 Medical Trap Hiding on Schedule A

You paid $3,200 for your kid's braces this year. You paid $2,100 for new glasses and contact lenses. You shelled out $4,500 in insurance deductibles and prescriptions. That is nearly $10,000 out of your pocket. Naturally, you expect your tax software to give you a massive tax break when April rolls around. Then you type those receipts into TurboTax, and your refund moves exactly zero dollars. You stare at the screen in disbelief. What happened?

You just ran face-first into the IRS Schedule A trap. Under standard tax rules, you can only deduct medical expenses that exceed 7.5% of your Adjusted Gross Income (AGI). If you and your spouse make $120,000 a year, your 7.5% hurdle is $9,000. That means the first $9,000 you spend on doctors, dentists, and medicine gives you zero tax write-off. On top of that, you only get to use those medical deductions if you itemize your taxes instead of taking the standard deduction. In 2026, the standard deduction for married couples sits at $30,000. Unless you have massive mortgage interest and state taxes, itemizing makes no sense anyway. So your $10,000 medical bill yields $0 in tax relief.

You are paying for healthcare with 100% post-tax cash. Every time you spend $10,000 on medical care, you actually had to earn roughly $14,000 before federal income tax, state income tax, and self-employment tax ate their slices. But if you run a small business, freelance full-time, or operate a single-member LLC, you do not have to settle for this trap. Internal Revenue Code Section 105 unlocks a legal workaround. It allows eligible business owners to pay for 100% of their family's medical expenses using pre-tax business income, skipping both income tax and the 15.3% self-employment tax entirely.

How Section 105 Turns Medical Bills Into Direct Business Deductions

An IRS Section 105 Health Reimbursement Arrangement (HRA) is an employer-funded plan that reimburses employees for out-of-pocket medical expenses tax-free. When a big corporate job offers an HRA, nobody blinks. But small business owners often do not realize they can set up the exact same structure for themselves. The catch is straightforward: IRS rules state that a sole proprietor cannot legally hire themselves as an employee to receive self-administered HRA benefits. However, if you are married, the IRS explicitly permits you to hire your spouse as a genuine employee of your business.

Here is how the magic happens. You hire your spouse to do real work for your business—handling administrative tasks, invoicing clients, managing customer service, or running your social media. As part of your spouse's employment compensation package, your business offers a Section 105 HRA. This plan promises to reimburse 100% of the employee's out-of-pocket medical, dental, and vision expenses. Because your spouse's HRA benefit automatically covers their spouse (you) and all dependent children under age 26, every single medical dollar your household spends becomes a fully deductible business employee benefit.

Instead of reporting these costs on Schedule A where they die under the 7.5% AGI floor, you write them off on Schedule C under Line 14 (Employee Benefit Programs). Look at what this move accomplishes:

• Federal Income Tax Slashed: Every dollar spent reduces your business profit dollar-for-dollar, cutting your overall federal income tax rate (typically 22% or 24%).
• Self-Employment Tax Wiped Out: Schedule C expenses directly lower your net self-employment earnings. You save 15.3% on social security and medicare taxes on every single medical dollar spent.
• State Tax Reduced: Lower net income means lower state income taxes in nearly every state with an income tax.

A dollar spent on medical care under a Section 105 HRA converts raw out-of-pocket expenses into a 35% to 45% discount, depending on your total income tax bracket.

The 4-Step Blueprint to Set Up Your Section 105 HRA

Do not simply start writing checks from your business checking account to your dentist and calling it an HRA. If you do that, an IRS auditor will disallow every deduction and hit you with penalties. You must establish a formal, documented plan. Follow this exact sequence to build your compliant medical tax engine.

Step 1: Define Real Job Duties for Your Spouse

Your spouse must be a legitimate employee who performs real, necessary work for your business. You cannot pay them $30,000 for 5 minutes of work. Draft a clear, written job description. Specify tasks such as bookkeeping, managing receipts, client follow-up, or maintaining your website. Pick a reasonable wage based on market rates—typically $18 to $25 an hour depending on the complexity of the work.

Step 2: Establish the Written Section 105 Plan Documents

The IRS requires a formal, written legal agreement setting up the Section 105 HRA before expenses are incurred. Do not try to write this contract yourself from scratch. Use a specialized low-cost administrator or software service that generates audit-proof documents instantly:

• Base605 / TASC: Excellent specialized platforms designed specifically for micro-business Section 105 HRAs. They generate all official plan documents, employee election forms, and summary plan descriptions for roughly $250 to $350 a year.
• PeopleKeep: A modern software platform that manages custom health reimbursement plans and keeps your records digital and organized.

Your plan document will state that the business reimburses up to a set maximum dollar amount (e.g., $15,000 per year) for qualified medical expenses incurred by eligible employees and their families.

Step 3: Put Your Spouse on Official Payroll

Pay your spouse a modest, real wage on a regular schedule (monthly or quarterly). Run this payroll through a proper payroll provider like Gusto or QuickBooks Payroll. Gusto handles all required tax filings (Form 941 and annual Form W-2). Here is an insider tip: Because your spouse works for a sole proprietorship owned by you, their wages are exempt from FUTA (Federal Unemployment Tax) under IRS rules. Keep their cash salary modest—say $3,000 to $5,000 per year. The real tax value lies in the tax-free Section 105 HRA reimbursements, not a huge cash salary.

Step 4: Execute the Reimbursement Protocol

Never pay healthcare providers directly from your business debit card. That creates messy recordkeeping. Instead, follow this clean trail:

1. You or your spouse pay for the doctor visit, contacts, or dental bill using your personal checking account or personal credit card.
2. Your spouse submits a simple one-page reimbursement claim form attaching the itemized receipt or Explanation of Benefits (EOB).
3. Your business writes a check or executes an online bank transfer from the business account directly into your spouse's personal account for the exact receipt total.
4. Log the transaction in your accounting software (such as Wave or QuickBooks Online) under "Employee Benefits - Section 105 HRA."

What Qualifies (and the Pitfalls That Trigger an IRS Red Flag)

The IRS uses Publication 502 to define what counts as a legitimate medical expense under Section 105. The list is far wider than most people realize. It goes way beyond basic doctor co-pays.

What You Can Deduct

• Dental and Vision: Cleanings, fillings, crowns, root canals, braces, eye exams, prescription glasses, laser eye surgery, and contact lens solution.
• Deductibles and Co-Pays: All out-of-pocket costs before your health insurance kicks in.
• Prescriptions and Medical Supplies: Prescription medications, asthma inhalers, insulin, blood pressure monitors, crutches, and bandages.
• Therapy and Mental Health: Licensed psychological counseling, physical therapy, chiropractic adjustments, and occupational therapy.
• Specialized Care: Infertility treatments (IVF), speech therapy, and hearing aids.
• Health Insurance Premiums: Under specific plan designs, Medicare premiums or individual health insurance premiums paid for your spouse's policy.

What Triggers an IRS Audit

IRS auditors scrutinize Section 105 plans when business owners cut corners. Protect yourself by avoiding these four common mistakes:

• Unreasonable Wages: Paying your spouse $50,000 a year for 2 hours a week of file organizing. Keep wages aligned with local market pay rates.
• No Written Plan Document: Simply writing off doctor bills on Schedule C without a signed Section 105 plan contract on file prior to the claims.
• Paying Expenses Directly: Wiping out personal doctor bills straight from the company business card without a claim form or personal receipt.
• Non-Qualifying Expenses: Trying to deduct cosmetic surgery, teeth whitening strips, general health club memberships, or over-the-counter vitamins (unless prescribed by a doctor for a specific diagnosed condition).

Decision Framework: Is a Section 105 Plan Right for You?

Not every business setup qualifies for this exact structure. Use this decision key to see if you should launch a Section 105 HRA today:

• If you are Married + Sole Proprietor / Single-Member LLC: This is the absolute sweet spot. Hire your spouse, set up the plan via Base605 or TASC, and begin deducting 100% of out-of-pocket health costs immediately.
• If you are Single + Sole Proprietor: You cannot hire yourself under a standard 105 HRA. Instead, look into a Qualified Small Employer HRA (QSEHRA) or maximize a tax-advantaged Health Savings Account (HSA) paired with a High Deductible Health Plan (HDHP).
• If you run an S-Corporation: S-Corp owners who hold more than 2% of company shares face special IRS restriction rules (IRS Notice 2008-1). Hiring your spouse inside an S-Corp does not work for a Section 105 HRA because the spouse is considered a 2% owner by attribution. If you operate an S-Corp, use the S-Corp health insurance premium write-off protocol instead, or utilize an HSA.

The Math: How a $12,000 Medical Bill Saves $4,200 in Cash

Let's look at real numbers to see why this setup matters. Meet Sarah. She works as an independent marketing consultant operating as a single-member LLC. Her net income before medical costs is $110,000. Her husband, Mark, helps manage her client billing and schedule for 5 hours a week. In 2026, their family spent $12,000 out-of-pocket on medical expenses—including $4,000 for their daughter's braces, $3,000 in deductibles, $2,000 for new glasses and dental care, and $3,000 in prescriptions and copays.

Scenario A: Standard Filing (Without Section 105)

Sarah files taxes using the standard deduction. Her $12,000 in medical bills sits below her 7.5% AGI threshold plus standard deduction limit. She receives $0 in tax relief.

• Gross Self-Employment Income: $110,000
• Self-Employment Tax (15.3% on 92.35%): $15,543
• Federal Income Tax (after standard deduction): $11,820
• Total Tax Paid: $27,363
• Medical Cost: $12,000 out of post-tax pocket.

Scenario B: With Section 105 HRA Built In

Sarah hires Mark at $20/hour ($3,000 annual cash wage). She executes a Section 105 HRA plan using Base605. She reimburses Mark for $12,000 in documented family medical expenses. On her Schedule C, she deducts $3,000 in wages and $12,000 in employee benefit programs (Line 14). Her net Schedule C profit drops from $110,000 down to $95,000.

• Net Self-Employment Income: $95,000
• Self-Employment Tax: $13,423 (Savings: $2,120)
• Federal Income Tax: $9,740 (Savings: $2,080)
• Total Tax Paid: $23,163
• Total Cash Saved: $4,200

By spending $300 on plan administration and setting up basic payroll, Sarah instantly put $4,200 back into her family bank account. She paid for her daughter's braces and her family's healthcare using 100% pre-tax income.

Stop throwing away thousands of dollars in medical deductions on Schedule A. If you run your own business and pay for your family's healthcare out of pocket, stop letting the IRS lock you behind the 7.5% AGI wall. Draft a job description, set up your written plan documents, put your spouse on payroll, and turn every medical receipt into a tax savings engine.
