Outlook:  Assuming no Democratic support, House GOP, with their 239-194 majority, can afford to lose only 22 votes; Senate GOP, with their slim 52-48 majority, can afford to lose only 2 votes (with the Vice president able to break a 50-50 tie.]

  • Democrats will oppose the bill because it is heavily skewed towards tax cuts for high-income taxpayers and there is little evidence that the proposed business or individual tax cuts will significantly increase economic growth or create jobs.
  • The bill could run into substantial procedural trouble in the Senate where the Byrd rule prohibits any revenue losses beyond the 10-year budget window, the effect of which is to require that tax cuts expire after 10 years unless fully paid for by that time.
  • The bill could run into substantial political trouble in both chambers because it repeals or caps a multitude of popular individual and business deductions and credits (see below) to pay for the reduction in tax rates.  Each economic sector will have to decide whether the rate reductions are worth the significant losses of current deductions and credits.
  • The distributional effects of the tax bill could also generate significant opposition to the bill.  By 2023, about 38 million households earning between $20,000 and $40,000 could end up paying higher taxes under the plan, compared to current law, according to testimony by the nonpartisan Joint Committee on Taxation.  In addition, by 2027, nearly one-third of the gross tax cuts would go to people earning over $1 million, and half would go to taxpayers earning over $200,000.
  • Bottom Line:  The bill as introduced is unlikely to pass; the question is whether the GOP will settle for slimmer 10-year tax cuts (and keep more deductions and credits in place) in order to claim a legislative achievement for 2017.  If the bill carries over into the 2018 election year, the chances of passage are more unlikely as political pressure from impacted interest groups becomes even more influential.

Fact Check:  Biggest tax cut in history?  No.  At a net 10-year cost of $1.4 trillion–i.e. tax cuts offset by tax increases–it is only the 7th or 8th largest according to the Tax Policy Center.

Summary of Key provisions follow [all revenue estimates cover 10 years, Fiscal Years 2018-27;  “cost” refers to revenue losses to the U.S. Treasury]:
