The tax is calculated based on premiums spent on “applicable employer-sponsored coverage.” The dollar thresholds in 2018 would have been $10,200 for individual coverage and $27,500 for family coverage. These dollar amounts are indexed so that if the tax does go into effect in 2022, and is not repealed or further delayed, the dollar thresholds will be higher as adjusted for inflation. The amount of the tax is 40 percent of the excess of the value of coverage over the dollar thresholds.
