ERC in one paragraph
The Employee Retention Credit was a payroll-tax credit available to employers affected by COVID-19 disruption in 2020 and 2021. It is a refundable credit applied against the employer's portion of Social Security tax, claimed retroactively via amended Form 941 filings. The credit window has closed; new claims are no longer eligible.
SIMERP preventative care tax savings in one paragraph
A SIMERP generates ongoing employer FICA tax savings - typically $53 per employee per month - by routing a qualifying portion of the employee's compensation through a Section 125 pre-tax election. It is not a credit. It is a reduction of the FICA-taxable wage base, which lowers both the employer's and employee's payroll tax liability.
The structural differences
- ERC was a one-time retroactive credit. SIMERP savings are ongoing and recur monthly for the life of the program.
- ERC required specific economic-disruption qualification criteria. SIMERP only requires W-2, 30+ hour employees on a qualifying group health plan.
- ERC was administered by amended payroll filings. SIMERP is administered through ongoing payroll integration.
- ERC has been the subject of intense IRS audit scrutiny since 2023 and is largely closed to new claims. SIMERP is on stable IRS footing and remains available.
Can both apply?
Yes. If your business legitimately qualified for ERC and properly claimed it within the original window, that claim is independent of your current SIMERP eligibility. The two operate on different mechanisms and do not interact.
The trap
The ERC-promoter-fraud wave in 2022-2024 has made some employers reflexively suspicious of any payroll-tax savings program. That suspicion is healthy when it is calibrated to the actual structure. The SIMERP mechanism is statutory and decades-old; the ERC promoter problem was about aggressive eligibility marketing, not about Section 125 reductions to the FICA-taxable wage base.
