Difference between Committee Bill and Senate
Bill (passed in the Senate on 12/2/2017)

Corporate Tax Rates & AMT

  • No special rate for personal service corporations
  • Corporate AMT repealed for taxable years beginning after 12/31/2017
  • Corporate AMT is not repealed

Cost Recovery / Full Expensing

  • 100% expensing for qualified property placed in service after 9/27/2017 and before 1/1/2023
  • Excludes property used by a regulated public utility but does not exclude property used in a real property trade or business or floor plan financing indebtedness
  • Does not extend to used property; retains requirement that original use begin with the taxpayer
  • Applies a phase-down (in 20% increments) of 100% expensing for five-year period beginning in 2023

Pass-Through Taxation

  • Senate Bill establishes a new 17.4% deduction for “qualified business income” from a pass-through or sole proprietorship
  • The deduction is generally limited to 50% of the taxpayer’s allocable share or pro rata share of “W-2 wages” paid by the partnership, S corporation or sole proprietorship; thus, if the partnership, S corporation or sole proprietorship does not pay W-2 wages, the owner/taxpayer’s deduction would be zero
  • W-2 wage limit would not apply in the case of a taxpayer with taxable income not exceeding $500,000 (for married individuals filing jointly) or $250,000 (for other individuals), but the application of this wage limit would be phased in for individuals with taxable income exceeding those amounts
  • The deduction applies to specified service businesses only for those taxpayers whose taxable income does not exceed $500,000 for married individuals filing jointly or $250,000 for other individuals. The benefit of the deduction for service businesses is phased out over the next $100,000 of taxable income for married individuals filing jointly or $50,000 for other individuals
  • This provision would expire 12/31/2015


  • Increases deduction from 17.4% to 23%
  • Extends application of the deduction to “qualified publicly traded partnership income,” as specifically defined

Repatriation “Toll Tax”

Previously untaxed foreign E&P earnings:

  • 10% cash and cash-equivalents
  • 5% non-cash assets
  • Payable over 8 years on a back-loaded basis
  • Proportional reduction in foreign tax credits attributable to previously untaxed foreign earnings
  • Increases the 10% and 5% rates to 14.5% and 7.5%
