This analysis highlights the immediate impacts of implementing a border adjustment tax on U.S. vehicle prices.

  • The border adjustment mechanism is being considered as an integral part of the major corporate tax reforms that are expected to be introduced in the 115th Congress.
  • Border adjustment is being considered as a way to generate sufficient tax revenues to offset the impact of lowering the overall corporate tax rate.
  • The border adjustment mechanism functions by excluding cash-inflow from overseas (export revenue) and cash-outflow to foreign countries (import costs) in the taxable profit calculation.
  • Automakers and suppliers that sell and manufacture in the United States are part of a highly globally-integrated industry.
  • The automotive industry would see significant changes to their tax base under a border adjustment; the tax would be highly disruptive to U.S. vehicle sales and production.


  • This analysis is based on confidential financial data received from automakers representing over 50 percent of
    U.S. light vehicle sales.
  • This analysis holds exchange rates constant, and examines only a price response to the implementation of border adjustment.
  • The estimates are based on the impact of the proposed border adjustment tax on imported vehicles as well as parts used for vehicle production in the United States.
  • This analysis estimates a price increase with no change in unit sales or domestic production—both of which would be affected by a price increase of this magnitude.


In response to the border adjustment:

  • U.S. light vehicle prices would increase 5.6 percent in immediate response to border adjustment.
  • Since the current U.S. average transaction price for new vehicles is $34,968 (Kelley Blue Book, 2017),
    average per vehicle price increases are estimated at $1,970.
  • Assuming U.S. sales at 17.5 million vehicles in 2016, the light vehicle price increase represents $34.6 billion in higher costs to consumers.
  • The $1,970 price increase resulting from the proposed border adjustment masks the turbulence and churn in the market which would significantly impact models, segments, and even entire companies.
