Bonjour Part 6 – Rosenbloom and Shaheen Brief In Support Of Bruyea

This is the sixth post in the “Bonjour” tax treaty series. In the fifth post I discussed that the U.S. Treasury is appealing both the Bruyea and Christensen cases. The dispute in these cases was over the issue of whether foreign taxes paid on investment income could be used as a tax credit against the Net Investment Income Tax. The background has been discussed in previous posts (See the appendix to this post). The precise is whether:

The Canada/U.S. tax treaty and the France/U.S. tax treaty (and similar treaties) allow for a foreign tax credit that is separate and independent of the foreign tax credits allowed under the Internal Revenue Code.

A foreign tax credit against the 3.8% NIIT is NOT permitted under the U.S. Internal Revenue Code. This means that, most Americans abroad who are subject to the NIIT will pay tax separately to BOTH the United States and their country of residence on the same investment income!

To put it another way: for Americans abroad, the Internal Revenue Code guarantees double taxation.

Can the tax treaties be interpreted to allow a foreign tax credit against the NIIT?

What follows is the Amicus brief authored by Professors Rosenbloom and Shaheen.

For better understanding here is a podcast which explains the Rosenbloom Shaheen amicus brief.

In addition, I wrote a more expansive version of this post for the Isaac Brock Society.

Does The Canada U.S. Tax Treaty Allow A Foreign Tax Credit Against The Net Investment Income Tax?

Appendix – The First five posts in the “Bonjour” series …

The four previous posts discussed the foreign tax credit rules in the context of the NIIT (“Net Investment Income Tax“). For a description of the first four posts, see the Appendix to this post.

The first post detailed the provisions of the U.S. France tax treaty which created the “three bite rule”. By creating the “three bite rule” the U.S. France treaty was used to create a treaty based foreign tax credit.

The second post (also based on the U.S. France tax treaty) described how the U.S. France tax treaty was used to create an independent treaty based foreign tax credit. The purpose was to allow for a foreign tax credit against the NIIT (“Net Investment Income Tax”). Although a major breakthrough, it’s important to note that this case (Christensen):

1. Found that the treaty should be interpreted to create an a foreign tax credit that was independent of the credits allowed under the Internal Revenue Code;

2. Specifically ruled that the language “subject to the limitations of the law of the United States” (found in the opening paragraph of the double taxation clause) should be interpreted to preclude a foreign tax credit for payment of foreign tax on foreign investment income.

The third post continued the “NIIT Tax Treaty Chronicles”. Specifically, this post detailed how Judge Solomson, in the case of Paul Bruyea, determined that (contrary to Judge Blank’s ruling in Christensen) that the “subject to the limitations of the law of the United States”clause in Article XXIV, Paragraph 1:

1. Does NOT preclude the use of a foreign tax credit to offset the NIIT; and

2. That Article XXIV, Paragraph 1 allows a U.S. citizen or U.S. resident living in Canada to use taxes paid to Canada as a credit against the U.S. NIIT!

Judge Blank in Christensen and Judge Solomson in Bruyea reached opposite conclusions with respect to whether the following clause (as represented in the 2016 U.S. Model Tax Treaty) can be used to create a foreign tax credit which is independent of the foreign tax credit rules in the Internal Revenue Code (Sections 27, 901 and 904).

Article 23

RELIEF FROM DOUBLE TAXATION

1. In the case of __________, double taxation will be relieved as follows:

2. In accordance with the provisions and subject to the limitations of the law of the United States (as it may be amended from time to time without changing the general principle hereof), the United States shall allow to a resident or citizen of the United States as a credit against the United States tax on income applicable to residents and citizens:

a) the income tax paid or accrued to __________ by or on behalf of such resident or citizen; and

Therefore, I expect that this issue has NOT been fully resolved.

Judge Solomson’s decision in Bruyea is a very exciting decision. It goes FAR beyond the decision in Christensen and opens the door to arguing that many (if not all) U.S. treaties guarantee that the NIIT can be offset by foreign tax credits!!

The fourth post focused on Judge Solomson’s comments in Bruyea about when a later in time statute can override an earlier treaty. In general he was of the view that a later statute can override an earlier treaty only when Congress expresses a clear intent to overrule the treaty.

Bonjour Part 6 – Rosenbloom and Shaheen Brief In Support Of Bruyea

Bonjour Part 5 – U.S. Treasury Appeals The Bruyea And Christensen Cases – Can A Tax Treaty Provide A Credit Independent Of The Internal Revenue Code?

Introduction

This is the fifth in a series of posts about “treaty basedforeign tax credits. Previous posts have discussed how the Bruyea and Christensen cases resulted in court rulings that U.S. tax treaties can create a foreign tax credit that is separate from and independent from tax credits allowed under the Internal Revenue Code. Of course, this depends on the terms of the treaty.

The facts as described in the Bruyea breif – filed September 2, 2025

STATEMENT OF THE ISSUES

Whether the Court of Federal Claims correctly determined that the income tax treaty between the United States and Canada (the “Canada Treaty”)1 allows a U.S. citizen resident in Canada to claim a treaty-based foreign tax credit against the net investment income tax (the “NIIT”) imposed by Section 1411 of the Internal Revenue Code of 1986 (26 U.S.C. — the “Code”).

SUMMARY OF ARGUMENT

For over 80 years, Canada and the United States have had income tax treaties in place, with the primary goal of preventing double taxation of the same income. Article XXIV of the Canada Treaty, entitled “Elimination from Double Taxation,” advances this purpose by providing that certain taxes imposed by each country are eligible for a foreign tax credit — a “treaty-based foreign tax credit” — even if otherwise not permitted under the internal laws of either country.

In 2010, Congress enacted the net investment income tax, the NIIT, which imposes a 3.8 percent tax on certain investment income generated by U.S. citizens (including those living abroad) and U.S. residents. Code Sec. 1411. For the 2015 tax year at issue, the Appellee, Paul Bruyea (the “Taxpayer”) was subject both to (1) Canadian taxation by virtue of his Canadian tax residency and (2) U.S. taxation by virtue of his U.S. citizenship. In that year, he sold real property located in Canada and paid more Canadian federal and provincial income taxes on that real estate gain than what he would have owed in total U.S. income tax and NIIT. As the Code does not provide a foreign tax credit — a “Code-based foreign tax credit” — against the NIIT, the IRS collected the NIIT on that same investment income on which he paid tax to Canada, resulting in double taxation. Here, the Taxpayer claims entitlement to a treaty-based foreign tax credit under Article XXIV of the Canada Treaty to offset the NIIT.

Framing the issue in the Bruyea case in simple terms:

The argument for allowing the credit: Bruyue argues that one would reasonably interpret the Canada/US tax treaty to allow a U.S. resident or citizen a foreign tax credit in the amount of the Canadian tax paid on that same income taxable, received at that same time, under the Internal Revenue Code.

The argument for denying the credit: U.S. Treasury argues that credit for the Canadian taxes paid on the income taxed by the United States is allowable ONLY to the extent that U.S. internal law (Internal Revenue Code) allows the credit.
