Cal. Code Regs. tit. 18, § 2439
(a) Sales for Resale. The burden of proving that prepaid MTS was purchased for the purpose of resale in the regular course of business is upon the seller unless the seller timely takes in good faith a certificate from the purchaser that the prepaid MTS is purchased for resale. It is rebuttably presumed that a purchase of prepaid MTS is for the purpose of resale in the regular course of business, if such a certificate is timely taken in proper form as set forth in subdivision (a)(1)(A) and in good faith from a person who is engaged in the business of selling prepaid MTS and has an emergency telephone account or a prepaid MTS account if the purchaser is required to register with the Department pursuant to Regulation 2437 or 2460. A certificate will be considered timely if it is taken at any time before the seller bills the purchaser for the prepaid MTS, or any time within the seller's normal billing and payment cycle, or any time at or prior to delivery of the prepaid MTS to the purchaser. A resale certificate remains in effect until revoked in writing.
(1) Form of Certificate.
(A) Any document, such as a letter or purchase order, timely provided by the purchaser to the seller will be regarded as a resale certificate with respect to the sale of the prepaid MTS described in the document if it contains all of the following essential elements:
(D) Qualified Resale Certificate. If a purchaser wishes to designate on each purchase order whether the prepaid MTS being purchased is for resale, the seller should obtain a qualified resale certificate from the purchaser that expressly directs the seller to the purchase orders, i.e., one that states “see purchase order” in the space provided for a description of the property to be purchased. Each purchase order must then specify whether or not the prepaid MTS covered by the order is purchased for resale. The use of the phrases “for resale,” “resale = yes,” “not subject to surcharge,” “surcharge = no,” or similar phrases on a purchase order, indicating that the 911 and 988 surcharges should not be added to the sales invoice will be regarded as designating that the prepaid MTS described in the purchase order is purchased for resale provided that the combination of the purchase order and the qualified resale certificate contains all the essential elements described in subdivision (a)(1)(A). However, a purchase order where the applicable amount of 911 and 988 surcharges is shown as $0 or is left blank will not be accepted as designating that the prepaid MTS described in the purchase order is purchased for resale, unless the purchase order also includes the phrase “for resale” or one of the other phrases described above to specify that the prepaid MTS is purchased for resale. If a purchase order does not so specify or is not issued timely within the meaning of subdivision (a), it will be rebuttably presumed that the prepaid MTS covered by that purchase order was not purchased for resale and that the purchase of the prepaid MTS covered by the purchase order was subject to the 911 and 988 surcharges. If a purchase order includes both prepaid MTS to be resold and prepaid MTS to be used, the purchase order must specify which prepaid MTS is purchased for resale and which prepaid MTS is purchased for use.
The seller shall retain copies of a purchaser's purchase orders along with the purchaser's qualified resale certificate in order to support the sales for resale to that purchaser.
(4) Other Evidence. A resale certificate which is not timely taken is not retroactive and will not raise the rebuttable presumption that a purchase of prepaid MTS is for resale in the regular course of business. Consequently, if a seller does not timely obtain a resale certificate containing the essential elements described in subdivision (a)(1)(A), the seller will be liable for the 911 and 988 surcharges due on a sale of prepaid MTS, unless the seller shows or the Department otherwise determines that:
(5) Use of XYZ Letters. A seller who does not timely obtain a resale certificate may use any verifiable method to establish that a sale of prepaid MTS was for resale. One method that the Department authorizes to assist a seller in satisfying its burden to establish that a sale of prepaid MTS was for resale or that the 911 and 988 surcharges were paid on a sale of prepaid MTS is the use of “XYZ letters.” XYZ letters are letters in a form approved by the Department which are sent to some or all of the seller's purchasers inquiring as to the purchaser's disposition of the prepaid MTS purchased from the seller. An XYZ letter will include certain information and request responses to certain questions, as set forth below. An XYZ letter may also be further customized by agreement between the Department's staff and the seller to reflect the seller's particular circumstances.
(A) An XYZ letter will request that a purchaser, the purchaser's employee, or the purchaser's authorized representative respond to the questions below regarding the purchaser's purchase or purchases of prepaid MTS from the seller, provide the purchaser's name, purchaser's emergency telephone account or prepaid MTS account number, and describe the nature of the purchaser's business. An XYZ letter will also request that the purchaser's response be signed by the purchaser, purchaser's employee or authorized representative, and include the printed name, title, and telephone number of the person signing the response, and the date signed.
An XYZ letter may include the following information: seller's name and emergency telephone account or prepaid MTS account number, dates of invoices, invoice numbers, purchase order numbers, amounts of purchases, descriptions of the prepaid MTS purchased, and other information identifying purchases of prepaid MTS from the seller. Copies of actual invoices may be attached to an XYZ letter.
(B) An XYZ letter will request that the purchaser, purchaser's employee, or purchaser's authorized representative check one of the boxes provided inquiring as to whether the prepaid MTS in question was:
(C) When the purchaser answers the third question affirmatively by checking the corresponding box, the XYZ letter will inquire further whether:
(b) Bad Debts. A seller of prepaid MTS is relieved from liability to collect the 911 and 988 surcharges imposed on prepaid MTS purchased from the seller in a retail transaction insofar as the base upon which the surcharges are imposed is represented by an account or accounts found worthless and charged off for income tax purposes by the seller, which includes circumstances where the seller's income is reported on a related person's income tax return and the account is charged off on that return, or if the seller is not required to file income tax returns and the seller's income is not reported on another person's return, charged off by the seller in accordance with generally accepted accounting principles. A seller that previously paid the 911 and 988 surcharges may claim a bad debt deduction for the percentage of the 911 and 988 surcharges paid that is equal to the percentage of the base upon which the 911 and 988 surcharges were imposed that is represented by an account or accounts found worthless and charged off for income tax purposes by the seller.
(1) Amount of Deduction or Refund.
(2) Worthless Account Subsequently Collected. A seller is liable for a percentage of the 911 and 988 surcharges if the seller was relieved of liability for any percentage of the surcharges or claimed a deduction or refund for any percentage of the surcharges under this subdivision and the seller subsequently collects any of the account upon which the relief, deduction, or refund was based from anyone, including a third party that purchased the account from the seller. The percentage of the 911 and 988 surcharges for which the seller is liable is equal to the percentage determined by dividing the amount collected by the base upon which the surcharges were originally imposed. The percentage of the 911 and 988 surcharges for which the seller is liable shall be included in the first return filed after such collection and shall be paid with the return. A seller is no longer liable for a percentage of the 911 and 988 surcharges on amounts subsequently collected on an account, after the seller has repaid the amount for which it was relieved of liability or claimed a deduction or refund.
Example 2. If the seller in Example 1 (above) sold the charged-off account receivable to a third party in January 2024 for $25 while the purchaser still owed $50 of the $100 purchase price upon which 911 surcharge was imposed, then the seller would be liable for 25 percent ($25/$100) of the original $0.30 911 surcharge imposed on the purchase of prepaid MTS or $0.08 (rounded up), which must be reported and paid with the seller's return for January 2024.
(3) Records. A seller must maintain adequate and complete records to support relief of liability or a deduction or refund for any percentage of the 911 and 988 surcharges showing:
This deduction must be taken on the return filed for the period in which the account or accounts were found worthless and charged off for income tax purposes or, if the seller is not required to file income tax returns, charged off in accordance with generally accepted accounting principles.
Failure to take the deduction on the proper return will not in itself prevent the allowance of a refund of the amount for which a seller could have taken a timely deduction provided a claim for refund is filed with the Department within the limitation periods specified in Revenue and Taxation Code sections 41101, 41101.1, and 41101.2.
Example 1. If a purchaser purchased prepaid MTS for $100 in December 2022 on credit provided by the seller, a $0.30 911 surcharge would be due on the purchase. If the seller's account receivable is charged off by the seller in December 2023 while the purchaser still owes $50 of the $100 purchase price for the prepaid MTS, which was the base upon which the surcharge was imposed, then the seller is relieved of liability to collect 50 percent ($50/$100) or $0.15 of the $0.30 911 surcharge imposed on the purchase of the prepaid MTS. If the seller already paid the $0.30 911 surcharge, then the seller may claim a $0.15 deduction on its return for December 2023 and if it does not, the seller may file a timely claim for refund for the $0.15.
(c) Lifeline Transactions. The purchase in a retail transaction in this state of prepaid MTS, either alone or in combination with mobile data or other services, by a prepaid consumer is exempt from the 911 and 988 surcharges if all of the following apply:
(2) The seller is authorized to provide lifeline service under the state or federal lifeline programs. If the seller is not an authorized provider of lifeline service, the exemption does not apply.
The state lifeline program means the program furnishing lifeline voice communication service pursuant to the Moore Universal Telephone Service Act (Pub. Util. Code, § 871 et seq.).
