Executive Summary: Tax Treatment: How the LLC and S Corp Structure Affects Deductibility and Product Design
LFP-16.05 — The Post-Medicare Market#
The tax treatment of health expenses for the 65-plus entrepreneur varies dramatically by business entity structure. IRC Section 162(l) establishes the self-employed health insurance deduction, an above-the-line deduction covering 100 percent of qualifying health insurance premiums for sole proprietors, partners, and more-than-2-percent S Corporation shareholders. The deduction reduces income tax but not self-employment tax. For Medicare premiums specifically, IRS Form 7206 instructions confirm that voluntarily paid Medicare premiums qualify for the deduction when the insurance plan is established under the trade or business.
S Corporations provide the most specific pathway. Under IRS Notice 2008-1, the S Corporation pays or reimburses the health insurance premium, includes the amount in the shareholder-employee’s W-2 Box 1 wages, and the shareholder deducts it on their personal return under Section 162(l). The premium is excluded from Boxes 3 and 5 (Social Security and Medicare wages) under IRC Section 3121(a)(2)(B), saving approximately $1,530 in combined employer and employee payroll taxes on a $10,000 annual premium. HRA reimbursements to shareholder-employees follow the same W-2 and deduction pathway, making out-of-pocket medical expenses equally deductible.
LLC treatment depends on tax classification. A single-member LLC taxed as a sole proprietorship deducts premiums under Section 162(l) but faces constraints on HRA participation because the owner lacks an employee relationship with their own business. A multi-member LLC taxed as a partnership routes premiums through guaranteed payments reported on Schedule K-1. An LLC with S Corporation election (Form 2553) follows S Corporation rules, combining LLC liability protection with S Corp tax treatment. This election is common among 65-plus entrepreneurs because it enables participation in employer-sponsored benefits including HRAs.
The professional knowledge gap is the core problem. The accountant understands entity structure and tax mechanics but not health benefit design. The insurance advisor understands coverage products but not entity-specific deductibility. Neither assembles the complete picture. The result is billions in uncaptured tax deductions across the 65-plus entrepreneurial population, with individual entrepreneurs leaving $2,000 to $5,000 annually on the table by paying health expenses from personal funds rather than routing them through properly structured business benefit arrangements. Silver incorporates tax structure as a core product component, including entity-specific enrollment processes, payroll coordination, and year-end tax documentation support for the entrepreneur’s accountant.
