For purposes of this chapter, the lease of an article (including any renewal or any extension of a lease or any subsequent lease of such article) by the manufacturer, producer, or importer shall be considered a sale of such article.
In the case of any lease described in subsection (a) of an article taxable under this chapter, if the tax under this chapter is based on the price for which such articles are sold, there shall be paid on each lease payment with respect to such article a percentage of such payment equal to the rate of tax in effect on the date of such payment, until the total of the tax payments under such lease and any prior lease to which this subsection applies equals the total tax.
Subsection (b) shall not apply to any lease of an article unless at the time of making the lease, or any prior lease of such article to which subsection (b) applies, the person making the lease or prior lease was also engaged in the business of selling in arm’s length transactions the same type and model of article.
If the taxpayer sells an article after the total tax has become payable, no tax shall be imposed under this chapter on such sale.
The term “total gas guzzler tax” means the tax imposed by section 4064, computed at the rate in effect on the date of the first lease.
