The blue ribbon for the Dumbest Tax in Obamacare goes to its tax on health insurance premiums, which the Joint Committee on Taxation estimates as raising $161 billion in revenue between 2019 and 2028. (The number would be higher, but for the fact that Congress passed a one-year premium tax holiday for 2019.) The problem is this: Health insurers aren’t in the business of going broke. So they pass along the cost of the tax in the form of higher premiums for consumers. According to estimates developed by consultants at Oliver Wyman, for every dollar Washington raises in taxes, premiums go up by around $1.27.
