Background
Paul Bruyea, a U.S. citizen residing in Canada, sold Canadian real estate in 2015. He paid Canadian income tax on the gain and also owed $263,523 in U.S. net investment income tax under 26 U.S.C. § 1411. He claimed a foreign tax credit for the Canadian tax to offset the NIIT, but the IRS disallowed the credit, and he paid the NIIT in full.
Bruyea sued for a refund in the Court of Federal Claims, arguing that Article XXIV of the U.S.-Canada tax treaty entitled him to the credit because it requires avoidance of double taxation. The trial court granted him summary judgment. The United States appealed, and Bruyea’s estate was substituted as appellee after his death during the appeal.
The Court’s Holding
The Federal Circuit reversed. It held that the Internal Revenue Code does not permit foreign tax credits to offset the NIIT. Sections 27 and 901 authorize those credits against taxes imposed under chapter 1, while Congress placed the NIIT in chapter 2A. The court treated that placement as an intentional exclusion of the NIIT from the foreign-tax-credit regime.
The treaty did not independently authorize a credit outside the Code’s limits. Article XXIV expressly makes the treaty credit subject to U.S. law, and that limitation applies to both the general credit provision in paragraph 1 and the credit for U.S. citizens residing in Canada in paragraph 4(b). The treaty’s broad coverage of U.S. income taxes, including the NIIT, did not mean every covered tax could be offset by a foreign tax credit. Because the treaty and Code were unambiguous, the court declined to rely on extrinsic materials urged by the estate.
Key Takeaways
- Foreign tax credits authorized by Code §§ 27 and 901 cannot offset the chapter 2A net investment income tax.
- Article XXIV of the U.S.-Canada tax treaty makes treaty-based credits subject to the provisions and limitations of U.S. law.
- The treaty’s objective of avoiding double taxation does not guarantee complete relief from every instance of double taxation.
Why It Matters
The decision forecloses use of the U.S.-Canada treaty to claim a foreign tax credit against the NIIT when the Code itself does not allow one. It also reinforces that a tax treaty’s general anti-double-taxation purpose cannot override an express clause incorporating domestic-law limitations.
For U.S. citizens living in Canada, foreign taxes paid on investment income may therefore remain unable to offset NIIT liability even when both countries tax the same income.
