Interim guidance statement regarding AT&T Services, Inc. v. Department of Revenue

This interim guidance statement expired on December 21, 2022 and was replaced by ETA 3236.2022 (AT&T Services, Inc. v. Department of Revenue).

December 20, 2021

This interim guidance explains the effect of the Thurston County Superior Court’s order in AT&T Services, Inc. v. Department of Revenue. This order invalidated portions of WAC 458-20-19402 (Rule 19402) for periods before June 12, 2014. The order does not impact Rule 19402 for periods on or after June 12, 2014.

Background

Washington adopted single factor receipts apportionment effective June 1, 2010.[1] Former RCW 82.04.462(3)(b) (2010) provided that, for purposes of calculating the receipts factor, gross income from apportionable activities is attributable to the state:

  1. Where the customer received the benefit of the taxpayer's service or, in the case of gross income from royalties, where the customer used the taxpayer's intangible property.
  2. If the customer received the benefit of the service or used the intangible property in more than one state, gross income of the business must be attributed to the state in which the benefit of the service was primarily received or in which the intangible property was primarily used.[2]

The Department adopted Rule 19402 interpreting this statutory language. Rule 19402 provided guidance that under subsection (3)(b)(i) of the statute, if a customer received the benefit of a service in multiple states and can reasonably determine the amount of apportionable receipts related to the benefit received in this state, such amount must be attributed to this state. This may be shown by applying a reasonable method of proportionally attributing the benefit among states (proportional attribution).

Effective June 12, 2014, the legislature amended RCW 82.04.462(3)(b)(i) to explicitly allow for proportional attribution.[3]

Summary of AT&T Services

  • AT&T Services challenged Rule 19402 in the Thurston County Superior Court, on the grounds that Rule 19402 exceeded the Department’s authority for periods before the June 2014 statutory amendment.[4]
  • On May 24, 2021, the court ordered that Rule 19402 is invalid to the extent it requires taxpayers to use proportional attribution for tax periods before June 12, 2014.
  • The Department did not appeal the court’s order in AT&T Services.

Effect of AT&T Services

As a result of the decision, taxpayers may qualify for a refund for taxes paid if:

  • The taxpayer used proportional attribution, as instructed by Rule 19402, when calculating their receipts factor for periods before June 12, 2014, and
  • This calculation resulted in overpayment of taxes for the relevant period(s).

No refund or credit may be made for taxes paid more than four years before the beginning of the calendar year in which a refund application is made, unless the taxpayer and Department have agreed to extend this time period.[5] Note: As a result of this nonclaim period, it may be in some taxpayers’ interests to submit refund applications by December 31, 2021, in situations where they believe they made an overpayment during calendar year 2017, for a pre-June 12, 2014 tax period. Failure to submit a timely refund application may bar a potential refund claim.

Next steps

  • The Department will review any refund requests implicating the AT&T Services decision and pre- June 12, 2014 tax periods on a case-by-case basis.
  • The Department plans to issue an excise tax advisory (ETA) in early 2022. This ETA will further address the effect of the AT&T Services decision.

[2] The statute lists additional cascading steps that apply if the taxpayer is unable to attribute gross income under subsections (3)(b)(i)-(ii).

[3] This amendment added the following language to subsection (3)(b)(i): “When a customer receives the benefit of the taxpayer's services or uses the taxpayer's intangible property in this and one or more other states and the amount of gross income of the business that was received by the taxpayer in return for the services received or intangible property used by the customer in this state can be reasonably determined by the taxpayer, such amount of gross income must be attributed to this state.” The amendment also provided language specifying that subsection (3)(b)(ii) applies if the taxpayer is unable to attribute gross income under subsection (3)(b)(i).
