Cal. RTC § 7051.2

(a) If a holder of a direct payment permit issued by the board pursuant to Section 7051.1 gives an exemption certificate to a retailer for the purpose of paying that retailer’s tax liability to the board, and fails or refuses to pay that retailer’s tax liability to the board on a timely basis, then in addition to that retailer’s tax liability, the direct payment permitholder shall be subject to the same penalty provisions that would apply if that permit holder was the retailer.

(b) If a holder of a direct payment permit issued by the board pursuant to Section 7051.1 does not properly allocate a retailer’s local sales and use tax liability, or that retailer’s district transactions and use tax liability, if applicable, to the cities, counties, city and county, redevelopment agencies, and districts to which those taxes would have been allocated if properly reported by that retailer, then the direct payment permitholder shall be liable to the state for a penalty of 10 percent of the amount of that retailer’s tax liability not properly allocated by the direct payment permitholder for improper allocation due to negligence or intentional disregard of the law.
