The Senate voted overwhelmingly today 65-33 in favor a $1.8 trillion package of spending bills and tax breaks, sending the legislation to President Obama’s desk for his signature. Included in the two bills are provisions trimming some of the levies that help finance ObamaCare. A tax on medical devices would be suspended for two years, a levy on health insurers would stop for a year and a tax on higher-cost insurance policies would be postponed two years until 2020.

It has been called into question whether it’s true that Sen. Marco Rubio is responsible for the provision (inserted into last year’s annual spending bill and now again into this year’s) that requires the risk-corridor program in ObamaCare to be budget neutral. Like this year’s giant spending law, last year’s omnibus bill was the result of a leadership-driven process that drew on substantive expertise from the relevant committee staffs but did not much involve most members of either house. But Rubio was without question the first and most significant congressional voice on this subject, and if he hadn’t done the work he did, the risk-corridor neutralization provision would not have been in last year’s (or this year’s) budget bill.

In a big package of tax and spending legislation that Congress is likely to approve this week, Republicans have forced President Obama to swallow three changes that undermine his signature health care law, including a two-year delay of a tax on high-cost insurance plans provided by employers to workers.

In an interview on Wednesday, Mr. Obama’s first budget director, Peter R. Orszag, a leading supporter of the Cadillac tax, said, “The two-year delay is likely to be equivalent to repeal of the tax because people will expect it to be deferred again and again.”

The Cadillac tax contained in the Affordable Care Act represented an attempt to remedy a major problem with health care and tax policy – the exclusion of the cost of employer-sponsored insurance from both income and payroll taxes. Regardless of political leanings, economists generally agree that the exclusion causes employers to offer overly expansive insurance. This depresses wages and increases overall health care spending. Moreover, the exclusion provides a disproportionate benefit to the wealthy.

It goes without saying that delaying a scheduled tax increase is a tax cut. According to the Joint Committee on Taxation, a two year delay of the Cadillac tax combined with deductibility will save taxpayers $20 billion over the next decade. Conservatives are for tax relief.

Conservatives are for repealing ObamaCare, in whole or in part. The Cadillac Plan excise tax is a part of how ObamaCare’s latticework of subsidies and regulations is supported. Delaying on the road to repealing parts of the ObamaCare law is good public policy. Eventually, we want to repeal and replace all of ObamaCare.

Some of my colleagues are blasting the Republican leadership for delaying three of ObamaCare’s taxes as part of the $1.14 trillion end-of-the-year tax extender and spending package scheduled for a House vote on Friday.

The legislation provides a two-year delay in the “Cadillac” tax on high-cost health insurance policies that labor unions were pleading to repeal; a two-year delay in the medical device tax that is drying up research budgets in this critical industry; and a one-year delay in the Health Insurance Tax (HIT).

The House reached a deal late Tuesday on a $1.1 trillion spending bill and a huge package of tax breaks. Throughout Tuesday, major components of the spending legislation appeared to be falling into place, including an agreement to alter major provisions of the Affordable Care Act, delaying a planned tax on high-cost health insurance plans and suspending a tax on medical devices for two years. Lawmakers also agreed to delay the Cadillac tax on high-cost employer-sponsored health plans by two years, originally scheduled to take effect in 2018.

Mere hours before a deadline to begin or renew insurance coverage through HealthCare.gov for Jan. 1, federal officials said consumers could have extra time to buy health plans. People who want to have ObamaCare coverage on the first day of 2016 now have until 11:59 p.m. PST on Thursday to sign up on the federal insurance exchange, the marketplace’s chief executive announced Tuesday night.

The two-year “Cadillac tax” delay under consideration by Congress is the worst kind of special-interest legislation. It will enrich labor unions and big business at the expense of taxpayers. ObamaCare’s Cadillac tax is a clunky but constructive first step in reforming the employer tax exclusion. It has problems—its structure as an excise tax is punitive, and it contains carveouts for favored Democratic constituencies—but the basic idea of equalizing the tax treatment of employer- and individually-purchased health insurance is a good one.

The 2015 United Auto Workers union contracts with General Motors Co., Ford Motor Co. and Fiat Chrysler Automobiles NV allow the companies to alter hourly-worker health plans if they are likely to trigger a 40% federal tax on some high-cost health-care plans. The most likely change: adding yearly deductibles for affected workers.
