    401(k) Plan Administration

    Trillium Payroll Services offers a seamless and integrated retirement arrangement for the complicated tasks of 401(k) recordkeeping and administration.  Reduce the amount of time you spend gathering data. Paycor ensures retirement information is automatically transferred from payroll records to retirement plan administration.

    Premium Only Plan (POP) / COBRA Services

    A Premium Only Plan (POP) is a way for employees to pay their portion of the group insurance premium on a pre-tax basis. It helps you and your employees save taxes. Your employees pay a portion of their group insurance premiums, and the premiums are deducted from their salaries before taxes are taken out. Then, with employee pre-tax income lowered, employers pay less employer-paid payroll taxes.  If you are over 20 employees, our COBRA services are a great benefit at no cost to you!
