WIMPER vs. SIMRP: Why the IRS Only Recognizes the SIMRP
People search for both names. Only one appears in IRS regulations, and the other depends on it.
4 min read
Short answer: SIMRP is the structure in IRS regulations (26 CFR § 1.105-11). WIMPER is a marketing name for programs that depend on it.
The short answer
They are not two competing plans. SIMRP, a self-insured medical reimbursement plan, is the structure that federal tax regulations recognize, in 26 CFR § 1.105-11. "WIMPER" is a marketing name that some providers use for wellness programs that rely on that structure. The IRS does not use the word "WIMPER."
Start with the real structure: The Complete Guide to Self-Insured Medical Reimbursement Plans (SIMRP) explains the plan the IRS actually regulates.
Side by side
| SIMRP | "WIMPER" | |
|---|---|---|
| What it is | A self-insured medical reimbursement plan | A marketing name for a wellness program |
| Named in IRS regulations? | Yes, 26 CFR § 1.105-11 | No |
| Can it stand alone? | Yes, when paired with a Section 125 plan and run correctly | No, it depends on a compliant SIMRP |
| Rules that apply | Nondiscrimination tests; payments tied to medical care or coverage | The same SIMRP rules |
Why this matters when you compare providers
Because the tax treatment comes from the SIMRP, evaluate any program by the SIMRP rules, not the label. Ask how the plan meets the nondiscrimination tests, how payments connect to real medical care or coverage, and how payroll and W-2s are coded. The IRS's 2023 memo, CCA 202323006, is a reminder that flat wellness payouts with no medical expense behind them are taxable wages, whatever the program is called.
