For taxable years beginning in 2018, the Affordable Care Act (ACA) imposes a 40 percent excise tax on high-cost group health coverage. This tax, also known as the “Cadillac tax,” is intended to encourage companies to choose lower-cost health plans for their employees. Found in Internal Revenue Code (Code) section 49801, the Cadillac tax provision taxes the amount, if any, by which the monthly cost of an employee’s applicable employer-sponsored health coverage exceeds the annual limitation (called the employee’s excess benefit). The tax amount for each employee’s coverage will be calculated by the employer and paid by the coverage provider who provided the coverage.
The Internal Revenue Service (IRS) is expected to issue guidance on the Cadillac tax requirements before they become effective in 2018.
