Republicans are right to want to repeal the mandate that fines Americans who don’t buy health insurance. Their dual motive is to repeal the most loathed part of the Affordable Care Act as well as to make tax reform comply with the Senate Byrd Rule that dictates no deficits outside a 10-year budget window. Some Americans no doubt would decide not to buy insurance if they aren’t hit with a tax, but that would be their choice. Republicans aren’t denying them anything. No other ObamaCare rule or mandate would be changed, and no benefit formula would be altered. Anyone who still wants an ObamaCare policy could still buy it.

As Republicans and the Trump administration continue trying to chip away at the Affordable Care Act, the Internal Revenue Service has begun, for the first time, to enforce one of the law’s most polarizing provisions: the employer mandate.

Thousands of businesses — many of them small or midsize — will soon receive a letter saying that they owe the government money because they failed to offer their workers qualifying health insurance. The first round of notices, which the I.R.S. began sending late last month, are being mailed to companies that have at least 100 full-time employees and ran afoul of the law in 2015, the year that the mandate took effect.

Senate Republicans have added the repeal of Obamacare’s individual mandate to the latest version of their tax bill, with several key swing votes saying they’re open to the idea.

Late on Tuesday, the chairman of the Senate Finance Committee, Orrin Hatch of Utah, released a new bill that would eliminate the mandate’s fines beginning in 2019. The addition was discussed at a closed-door party lunch meeting earlier in the day, and several Republican senators said no one spoke out publicly against repealing the mandate.
