The Federal Insurance Contributions Act (FICA) is a federal law that requires employers to withhold certain taxes from employees’ wages and these taxes are used to fund Social Security and Medicare. Employers must provide an accurate count of FICA eligible employees to assist with calculations for pretax medical insurance premiums, benefit determinations and coordination of benefits. Additionally, insurers and employers, pursuant to Massachusetts and federal law, have shared reporting requirements. The reporting requirements are split between each insurer and employer based on the number of part time, full time and full-time equivalent employees. Therefore, it is required that the section related to full time and part time employees be completed on the Employer Group Application.
