Return of ACA insurer tax will bring in $15.5 billion

Health insurance companies will have to pay $15.5 billion next year if the Affordable Care Act's tax on insurers resumes as planned, the IRS said in a notice on Tuesday.

The big picture: Insurers hate the tax because it eats into profits, and companies pass along the costs to consumers through higher premiums. The industry has a few months left to persuade lawmakers to delay or kill the tax.
