I've seen at least a couple posts in this forum and others that suggest that TX "double taxes" lease buyouts. I was actually convinced that was indeed fact and may of even posted a similar comment. However, TX Administrative Code, Title 34, Part 1, Chapter3, Subchapter F, Rule 3.70 Motor Vehicle Leases and Sales, subsection (C) states the following:
"If the transaction is considered to be a sale and not a lease, as described in subsection (b) of this section, no additional motor vehicle sales tax is due at the time the initial lessee/purchaser takes title to the vehicle, provided the correct amount of tax was previously paid on the total consideration. If the correct amount of tax was not paid on the total consideration, the lessee/purchaser must pay the difference when the vehicle is titled in his name."
I live and MD and the TX law appears to be similar where if the initial lessee buys the vehicle, additional taxes are waived even though there is technically a change in ownership from the lessor to the buyer.
