The so-called Cadillac tax is an excise tax on high cost health plans offered by employers. Beginning in 2020, health plans that cost more than $10,200 for an individual or $27,500 for a family plan will be subject to the tax, which is 40% of the amount that exceeds those thresholds. For example, if a family plan costs $30,000, the employer that offers the plan would owe 40% of $2,500 ($30,000 minus $27,500), or $1,000 for each family it covers under that plan.
The tax was intended to be a disincentive for employers to provide overly rich health benefits, and the cost of the health plan is one measure of the level of benefits. However, some plans may cost more because they cover people with higher-than-average health care costs, including retirees, older workers and workers in high-risk occupations. The cost thresholds for plans that cover a significant number of individuals in any of those categories are higher.
