Texas Tax Code - TAX § 158.052. Computation of Tax

The initial sale of a manufactured home occurs on the sale, shipment, or consignment by a manufacturer to a retailer or other person in this state. The tax rate is applied to 65 percent only of the sales price to be paid by the retailer or other person, as set forth in the actual invoice or bill of sale. The sales price does not include any shipping, freight, or delivery charges for the manufactured home from the manufacturer to the retailer or other person if those charges are separately stated on the invoice or bill of sale.
