Cal. Code Regs. tit. 18, § 1701
(a) Procedure in General. A retailer who resells tangible personal property before making any use thereof (other than retention, demonstration or display while holding it for sale in the regular course of business) may take a deduction of the purchase price of the property if, with respect to its purchase, he has reimbursed his vendor for the sales tax or has paid the use tax. If such a deduction is taken by the retailer, no refund or credit will be allowed to his vendor with respect to the sale of the property.
The deduction under the caption “Tax-paid purchases resold” must be taken on the retailer's return in which his sale of the property is included. If the deduction is not taken in the proper quarter, a claim for refund of tax must be filed.
(b) Circumstances Warranting Use. This procedure should be used in any of the following circumstances:
