"In substantial part" means that the motor vehicle or trailer for which exemption is claimed actually crosses Washington boundaries and is used a minimum of twenty-five percent in interstate for hire hauling .
ABC Trucking keeps a journal showing the origin and destination for each haul that identifies each truck or tractor and trailer used on a per unit basis. This journal is reviewed at the end of each calendar year to verify compliance with the statutory provision that motor vehicles and trailers be substantially used for transporting persons or property for hire across the boundaries of the state. During the first year of use, all five of the trailers met the "substantial use" threshold. However, for the 2013 calendar year, ABC Trucking determines that two of the trailers failed to meet the twenty-five percent "substantial use" threshold. ABC Trucking must remit use tax directly to the department on its last excise tax return filed for 2013, based on the fair market values of the two trailers as of January 1, 2013. Because the taxpayer maintained specific usage records for each trailer, the "substantial use" in interstate hauling must be met by each trailer for which exemption is claimed. If detailed records for usage of trailers had not been kept, use tax liability of the trailers would have been based on the tractors. In any event, use tax liability may not be determined based on the overall experience of a fleet of vehicles. If a vehicle is used both in hauling for hire and in hauling the carrier's own products, the "substantial use" is determined solely on the usage in for hire hauling .
DB Carriers keeps a journal showing the origin and destination for each haul that identifies each truck used on a per unit basis. This journal is reviewed at the end of the 2012 calendar year, and DB determines that the truck failed to meet the twenty-five percent "substantial use" threshold. DB Carriers must remit use tax directly to the department on its last excise tax return filed for 2012, based on the fair market value of the truck as of January 1, 2012. DB Carriers may not compute the use tax liability based on the December 31, 2012, fair market value as the vehicle never satisfied the substantial interstate use provision of RCW 82.12.0254.
BG determines that this truck failed to meet the twenty-five percent substantial use threshold for calendar year 2014. Use tax will be due beginning with the period for which the exemption was not met, in this case beginning with January 2014. However, BG Hauling may report use tax only on each lease payment in which payment period there was actual instate use, provided it maintains accurate records substantiating the truck's instate and out-of-state activity. If BG Hauling continues to lease this truck in 2015, usage will again be reviewed for that period and use tax may or may not be due for the 2015 lease payments, depending on whether the vehicle was used substantially in interstate hauls during that year.
Based upon the truck's for hire hauling activities during the 2014 calendar year, MG determines that the use of the truck failed to satisfy the twenty-five percent substantial use threshold. MG must remit use tax on the amount of lease payments made during 2014 at the time it files its last tax return for 2014. Provided accurate records are maintained to substantiate instate and out-of-state use, MG may remit use tax on each lease payment in which the payment period there was actual instate use. While only the hauling for hire activities are reviewed when determining whether the truck satisfies the substantial interstate use threshold, once it is established the exemption cannot be maintained, the use tax liability is based upon all instate activity, including the motor carrier's hauling of its own product.
