The High Cost Employer-Sponsored Health Coverage Excise Tax, more commonly known as the Cadillac Tax, is scheduled to take effect in 2018. The Cadillac Tax is described as an attempt to reduce health care usage and costs by encouraging employers to offer health plans that are more cost effective and that engage employees in the cost of care.  Experts estimate that the tax will raise $80 billion over a 10 year time period and will finance various components of the Affordable Care Act (ACA).
