On May 31, 2016, the Washington Department of Revenue (DOR) Appeals Division released a Determination (No. 15-0251, 35 WTD 230) denying a German pharmaceutical company’s business and occupation tax (B&O) protest. The administrative law judge (ALJ) ruled that while the nondiscrimination provisions contained in Article 24 of the US-Germany Income tax Treaty (Treaty) “may apply,” the B&O does not discriminate against non-US businesses because it is imposed on any business deriving royalty income from Washington sources and applies equally to foreign and US companies. The ALJ also found that the company could avoid double taxation of the royalty income by excluding income taxed by Washington from its German tax base. While the company also challenged the constitutionality of the 2010 B&O economic nexus law, the ALJ declined to entertain it—citing a lack of authority to rule on the constitutionality of Washington statutes.
