New Mexico (455 U.S. 720, 1982), the Supreme Court established that a state may impose a non-discriminatory tax on the income of a private company derived from a federal contract, even if the work is performed on federal property or involves federal activities. The court held that the tax did not violate the federal government’s immunity from state taxation because it was not directly imposed on the federal government itself.
Example 4: International Tax Agreements and Business Substance
- Context: International tax agreements and the concept of business substance can impact a company’s tax obligations.
- Case Study: In a recent case, a company set up a wholly-owned subsidiary in Luxembourg to serve as a holding company for its European and American subsidiaries. The Luxembourg subsidiary received royalty payments from a U.S. company for the use of trademarks. The U.S. tax authorities initially challenged the tax-free treatment of these payments under the U.S.-Luxembourg tax treaty, arguing that the Luxembourg company lacked sufficient business substance. After a review of the company’s activities, the U.S. tax authorities ultimately allowed the tax-free treatment for one year but required tax payments for another year due to insufficient evidence of business substance.
