Employer flex contributions will reduce the amount of an employee’s premium contribution only if the amount may not be taken as cash, is used to purchase minimum essential coverage and may only be used for medical care (as per IRC Code Section 213)
Cash in lieu of benefits does not apply to the affordability analysis
Employer contributions to Health Reimbursement Arrangements (HRA) may reduce the employee’s required contribution for affordability for the employer mandate – thus the amount that an employer has agreed to contribute to an HRA reduces the amount the employee is deemed to “owe” for their health insurance (e.g. $1,200 HRA technically reduces the counted premium for the employee by $100 per month, even though it does not support the premium)
