To report partner health insurance on Form 1065, treat the premiums as guaranteed payments under IRC Section 707(c): include the total on Line 10 of the partnership return, then break out each partner’s share on Schedule K-1 in Box 4a (as part of the Box 4c total) and separately in Box 13 using Code W.1Office of the Law Revision Counsel. 26 U.S. Code 707 – Transactions Between Partner and Partnership That one classification carries the deduction on the partnership’s side and sets up the partner to claim the self-employed health insurance deduction on their 1040. Miss any piece of it and the deduction can disappear.
Why the Premiums Have to Be Guaranteed Payments
Partners are owners, not employees, so a partnership cannot deduct a partner’s health insurance the way a corporation deducts coverage for a W-2 worker. The IRS requires the premiums to be run through as guaranteed payments, which Section 707(c) defines as compensation to a partner determined without regard to partnership income.1Office of the Law Revision Counsel. 26 U.S. Code 707 – Transactions Between Partner and Partnership The same rule applies to members of a multi-member LLC filing as a partnership.
The classification does two jobs at once. The partnership gets a deduction for the premiums as a business expense, reducing ordinary business income. The same amount lands in the partner’s gross income, which is what gives the partner the earned-income base needed to claim the self-employed health insurance deduction on their personal return.2Internal Revenue Service. Publication 541 – Partnerships
If the partnership instead treats the insurance cost as a reduction in the partner’s distributions, the partnership loses the deduction entirely.2Internal Revenue Service. Publication 541 – Partnerships The premiums vanish into the partner’s capital account and nobody gets a tax benefit.
Confirm the Plan Is Established Under the Partnership
Before the reporting mechanics matter, the plan has to qualify as established under the partnership’s business. The IRS recognizes three arrangements that meet this test:3Internal Revenue Service. Instructions for Form 7206
- The partnership pays the premiums directly to the insurer. The policy can be in the partnership’s name or the partner’s name.
- The partner pays the premiums personally and the partnership reimburses the partner, then reports the reimbursement as a guaranteed payment on the K-1.
- The policy is held in the partnership’s name and paid by the partnership. This is the cleanest setup.
What does not qualify: the partner pays premiums personally and is never reimbursed. In that case the plan is not considered established under the business, and the self-employed health insurance deduction is off the table.3Internal Revenue Service. Instructions for Form 7206
Entering the Premiums on Form 1065
The aggregate health insurance premiums for all partners go on Line 10 of Form 1065, the line for guaranteed payments to partners. The IRS instructions specifically direct you to include on Line 10 any amounts paid during the tax year for medical care insurance covering a partner, a partner’s spouse, dependents, and children under age 27.4Internal Revenue Service. 2025 Instructions for Form 1065 Combine these amounts with any other guaranteed payments the partnership makes for services.
Because Line 10 is a page-one deduction, it reduces the partnership’s ordinary business income before anything flows out to the partners. The same total also appears on Schedule K, Line 4, which tracks aggregate guaranteed payments allocated across all partners. The Schedule K total should tie to Line 10, assuming all guaranteed payments are for services or insurance; payments for use of capital have their own treatment.
Even though Line 10 is a single number, keep each partner’s premium amount tracked separately in the books. That partner-by-partner detail is what drives every individual K-1.
Reporting on Each Partner’s Schedule K-1
Each partner needs two separate entries on their K-1 for the premiums to work correctly on their 1040.
Box 4a and Box 4c: Including the Premium as Income
Report the partner’s share of the health insurance premiums in Box 4a, guaranteed payments for services. Box 4c is the total of 4a and 4b (payments for use of capital).5Internal Revenue Service. Instructions for Form 1065 The IRS treats health insurance premiums as payments for services rendered as a partner, which is why they belong in 4a.
This inclusion is what puts the premium amount into the partner’s gross income. Reporting insurance as income can feel backwards, but it is the mechanical step that creates the earned-income base the self-employed health insurance deduction needs. No income inclusion, no deduction.
Box 13 With Code W: Flagging the Deduction
Separately, report the exact premium amount in Box 13 using Code W, the specific identifier for payments of a partner’s health insurance.5Internal Revenue Service. Instructions for Form 1065 Code W tells the partner (and the IRS matching system) that this amount qualifies for the self-employed health insurance deduction.
Box 13 Code W is a signal, not a direct deduction from K-1 income. The partner takes that number to their Form 1040 and calculates the actual deduction there. The Code W figure should equal the health insurance portion included in Box 4a. Do not slot the premiums under any other Box 13 code.
What the Partner Does Next on Form 1040
With the K-1 in hand, the partner claims the self-employed health insurance deduction as an above-the-line adjustment on Schedule 1 (Form 1040), Line 17.6Internal Revenue Service. Schedule 1 (Form 1040) – Additional Income and Adjustments to Income It reduces AGI directly, so the partner does not need to itemize to benefit.
The deduction cannot exceed the partner’s earned income from the partnership business under which the plan is established.7Internal Revenue Service. Instructions for Form 7206 Most partners can compute the deduction with the worksheet in the Form 1040 instructions. Form 7206 is required only when the partner has more than one source of self-employment income, files Form 2555 for foreign earned income, or is including qualified long-term care premiums in the deduction.3Internal Revenue Service. Instructions for Form 7206
Any premium amount that exceeds the earned-income cap is not lost. The partner can carry those excess premiums to Schedule A as a medical expense if they itemize, subject to the 7.5% of AGI floor.8Internal Revenue Service. Topic No. 502 – Medical and Dental Expenses
Two Things the Reporting Does Not Do
The guaranteed-payment treatment is included in the partner’s net earnings from self-employment, so the partner owes self-employment tax on the premium amount. The self-employed health insurance deduction reduces income tax only; it does not reduce SE tax.9Internal Revenue Service. Instructions for Form 7206 – Section: Effect on Self-Employment Tax Partners sometimes assume the deduction wipes out the full tax impact; it does not.
The deduction also disappears for any month the partner was eligible to participate in a subsidized health plan maintained by any employer, including a spouse’s or dependent’s employer. Mere eligibility disqualifies the month, whether the partner enrolled or not. The test runs month by month.7Internal Revenue Service. Instructions for Form 7206 Correct 1065 reporting does not override this partner-level limit.
HSA Contributions Follow a Parallel Path
If the partnership also contributes to a partner’s Health Savings Account, those contributions are treated as guaranteed payments under Section 707(c), deductible by the partnership and includible in the partner’s gross income on Schedule K-1. Unlike employer contributions to an employee’s HSA, these are not excludable from the partner’s gross income under Section 106(d). The partner claims the HSA deduction as an adjustment to income on their personal return, and the amount is subject to self-employment tax.10Internal Revenue Service. Notice 2005-8 – Health Savings Accounts
Common Reporting Mistakes That Break the Chain
Treating premiums as a distribution instead of a guaranteed payment. This is the most damaging error. Reducing the partner’s capital account for the insurance cost rather than running the premiums through Line 10 means nobody gets a deduction. The partnership records a draw, the partner sees reduced distributions, and the pathway to the self-employed health insurance deduction is gone.2Internal Revenue Service. Publication 541 – Partnerships
Omitting Box 13 Code W. Some preparers include the premiums in Box 4 but forget the Box 13 Code W entry. The partner has the income inclusion with no notification of the deduction amount. Deduction eligibility technically survives, but the missing code causes confusion on the 1040 and can trigger IRS matching issues.
No actual reimbursement when the partner pays directly. When the policy is in the partner’s name and the partner pays, the partnership has to actually reimburse the partner and report the reimbursement on the K-1. A verbal arrangement that “the partnership covers insurance” does not satisfy the established-plan requirement.3Internal Revenue Service. Instructions for Form 7206
Mismatch between Box 4a and Box 13 Code W. The health insurance portion of guaranteed payments in Box 4a should equal the Code W amount in Box 13. A discrepancy means one of the two was computed wrong, and it will surface when the partner tries to tie out the deduction.
Reporting premiums under a different Box 13 code. Code W is the only correct identifier for partner health insurance. Using another code (or burying the amount in a general “other deductions” line) defeats the purpose of the K-1 reporting and leaves the partner without the information they need.
