Semi-Trailer Tax Parity Act

This bill amends the Internal Revenue Code of 1986 to extend the application of floor plan financing interest rules to include semi-trailers and truck trailers. Specifically, it modifies Section 163(j)(9)(C) to expand the definition of property eligible for these rules to encompass truck trailer or semi-trailer chassis and bodies , regardless of whether it's a first retail sale. The expansion of these rules means that businesses financing the inventory of these specific types of trailers will be able to deduct the interest paid on those loans. This provision aims to provide tax treatment parity for dealers of semi-trailers, aligning them with dealers of other motor vehicles. The amendment will apply to taxable years beginning after the date of the Act's enactment.
