Colorado Family and Medical Leave Insurance Program Setup for PLLC, Professional Corporation, LLP, LLC, Corporation

Employers with Colorado employees must provide Family and Medical Leave Insurance (FAMLI). The premium is currently set to 0.9% of the employee’s wage, with 0.45% paid by the employer and 0.45% paid by the employee. Employers may elect to pay the full amount of 0.9% if they choose to offer this as a benefit for their employees. Employers with nine or fewer employees nationwide do not have to contribute to the program but do need to remit their employees' share of the premium on behalf of employees each quarter.
