Congressional Republicans still have an opportunity to relieve constituents of at least one Obamacare regulation before 2017 is up.

Obamacare’s health insurance tax, previously delayed by Congress, is set to take effect on Jan. 1, 2018 The regulation hits insurance companies with a 4-6 percent tax on every plan sold. As the Washington Post reported earlier this month, “UnitedHealth Group and a coalition of other groups against the tax have been circulating research from Oliver Wyman estimating that premiums will rise 2.6 percent next year if the tax is allowed to go into effect.”
