Structuring Employee Contributions for Group Health
Employee contributions are the portion of monthly health insurance premiums paid by the employee rather than the employer. California law requires the employer to contribute a minimum of 50% of the lowest-cost HMO plan's employee-only premium. Everything above this minimum is a business decision — competitive employers typically pay 75–100% of employee-only premiums to attract and retain staff.
Employee contributions are deducted from payroll pre-tax when a Section 125 cafeteria plan is in place (which every employer with a group health plan should have). Pre-tax deductions reduce the employee's taxable income for federal and state income tax, Social Security, and Medicare — saving employees 25–35% on their premium contributions. Employers save 7.65% in FICA match on employee contributions made pre-tax.
Common Contribution Structures
Flat dollar contribution: employer pays a fixed dollar amount per month regardless of plan chosen (e.g., $600/employee/month). Employee pays the difference if they choose a more expensive plan. Simple to administer. Percentage contribution: employer pays a percentage of the premium (e.g., 80% of any plan chosen). Higher contributions for higher-cost plans. Reference-based pricing: employer pays 100% of the lowest-cost HMO premium; employees pay the full additional cost if they choose PPO. This "defined contribution" approach controls employer costs while offering choice.
Dependent Contribution Strategies
Employers are not required to contribute to dependent (spouse, children) premiums. Most do not — dependent premium contributions become a significant employee out-of-pocket cost. A family on a PPO might pay $1,200–$1,800/month in employee-paid dependent premiums. Some competitive employers contribute 50% of dependent premiums as a differentiating benefit, particularly for roles with dependent-age children. This is expensive but highly valued by employees with families.
ACA Affordability Considerations
The ACA affordability test only applies to ALEs (50+ FTE) and only tests the employee-only premium. Coverage is affordable if the employee's share of the self-only premium doesn't exceed 9.12% of their W-2 wages (2024). If you have employees earning $35,000/year, the maximum employee contribution for ACA affordability is $3,192/year = $266/month. Plan your contribution strategy so lower-wage employees can afford coverage without triggering ACA penalties.
