The “Cadillac” tax, an excise tax that will be levied on large employers who offer high-cost health care insurance plans in 2018, is already having an effect on benefits packages. Employers such as Kaiser Permanente are beginning to trim their health plan offerings, resulting in costlier health plans to the employee. The tax, which is being used to support the costs of the Affordable Health Act as well as to remove “overly generous” health plans, has been controversial for both employers and unions alike. Both Republican and Democratic congress members are calling for the measure to be repealed, with strong support coming from large health care corporations such as Pfizer and Cigna.
