(a) In general. In the case of a highway motor vehicle that, for any taxable period, has a base for registration purposes in a contiguous foreign country, the tax imposed by section 4481 for such taxable period shall be 75 percent of the tax that would be imposed but for this section. A highway motor vehicle has a base for registration purposes in a contiguous foreign country in any taxable period in which such vehicle is registered under the laws of a contiguous foreign country and such vehicle is not registered under the laws of any of the United States other than proportionately registered under a proration agreement (such as the International Registration Plan). A highway motor vehicle is not considered to have a base for registration purposes in a contiguous foreign country in any taxable period in which such vehicle is registered under the laws of any of the United States and such State is required under Sec. 41.6001-2(b) to receive proof of payment of the tax imposed by section 4481(a) with respect to such highway motor vehicle. For purposes of this paragraph (a), a highway motor vehicle that is allowed to operate in a State under a reciprocity agreement is not considered to be registered under the laws of that State.
(b) Contiguous foreign country. The term ``contiguous foreign country'' means Canada or Mexico. [T.D. 8159, 52 FR 33584, Sept. 4, 1987, as amended by T.D. 8177, 53 FR 6626, Mar. 2, 1988]
