The SIMERP Plan

A SIMERP plan is an employer-sponsored benefit structure built on IRS Section 125 that legally reduces the amount of gross wages subject to FICA taxation. When employees participate, a qualifying portion of their compensation is reclassified as a pre-tax benefit rather than wages. The IRS does not assess FICA taxes on that portion, so your employer tax liability drops. The employee’s net pay is maintained or improved. The plan runs through your existing payroll cycle with no change to how your payroll is processed.

The SIMERP plan does not replace or alter your payroll provider. It adds a benefit layer that is applied before the FICA calculation runs. Your current payroll platform continues to process wages, deductions, and filings exactly as it does today. The only change is that a portion of qualifying employees’ compensation routes through the benefit structure before taxes are assessed. Most implementations are complete within 30 days of plan design approval.

SIMERP is built entirely on IRS Section 125, which has governed pre-tax benefit plans since 1978. It is the same legal framework behind health flexible spending accounts and dependent care accounts that millions of U.S. businesses already use. The tax treatment — excluding qualifying pre-tax benefits from FICA — is explicitly permitted under the Internal Revenue Code. A properly structured and documented plan is fully defensible under IRS audit. We encourage every client to have their CPA review the plan design before implementation.

The maximum reduction is $638.98 per participating employee per year. Your actual savings depend on your employee count, average wage levels, and the number of employees who enroll. A business with 30 qualifying employees could reduce its annual FICA expense by more than $19,000. We run a full payroll analysis before any implementation so you see the projected savings in writing before you commit to anything.

No. Participating employees maintain the same net take-home pay — in many cases their pay improves slightly because their own FICA contribution is also reduced on the benefit portion. The plan is voluntary; employees who choose not to participate remain on standard payroll without any change to their compensation. Existing benefits — health insurance, retirement plans, PTO — are not affected.

Any U.S. business with W-2 employees paying employer FICA taxes is a potential candidate. Industries with the strongest results include retail, hospitality, healthcare, construction, staffing, and manufacturing — sectors with high employee counts relative to revenue. Businesses with 10 to 200 employees and average wages between $30,000 and $90,000 capture the most significant savings. If you already have a Section 125 plan in place, we audit it for compliance gaps and missed savings before assuming it is properly optimized.

From initial payroll analysis to active plan implementation, the typical timeline is 30 days. The analysis phase — where we review your payroll records and calculate projected savings — takes 5 to 10 business days. Plan design and documentation follow. Employee enrollment and communication materials are prepared before the plan goes live. Your team’s time commitment during implementation is minimal; we handle the documentation and enrollment process.

There is no upfront cost, retainer, or consulting fee. CR Advantage Group operates on a performance-based model: our compensation is a percentage of the savings we document and deliver. If the analysis does not identify meaningful savings, we tell you before any implementation begins and you owe nothing. If the plan delivers less than projected, you pay based on actual results. The only scenario in which you pay us is the scenario where your business is paying less in FICA taxes than it was before.
