# SIMERP > SIMERP is a Self-Insured Medical Expense Reimbursement Plan. It redirects an > employer's FICA payroll tax into real medical care for employees, at no net > cost to the business. Employees' gross pay does not change and their > take-home pay goes up. The employer keeps its existing broker, health plan > and payroll provider. For employers with 25 to 3,000+ W-2 employees, in all 50 states. Not insurance. A self-insured medical reimbursement plan the employer sponsors. ## The numbers - Average recovery: $640 per enrolled employee per year - Average FICA saved: $93.33 per enrolled employee per month - Kept after every program cost: $53.33 per enrolled employee per month - Launch: 30 to 60 days, typically under 5 hours of the HR team's time - First savings appear on the next payroll ## The statutes IRC 105, 106, 213(d) and 3121 have been law since the Internal Revenue Code of 1954. IRC 125 followed in the Revenue Act of 1978. Treasury Regulation 1.105-2 draws the line the IRS enforces: reimbursements must be tied to actual medical care, never paid irrespective of whether medical expenses are incurred.
