US Continental Shelf Definition of the United States | US Tax Attorney
The US continental shelf presents a unique problem to the tax definition of the United States. It is governed by a special tax provision that sets it apart from any other tax definition. If fact, the US continental shelf is only considered to be part of the United States with respect to specific taxpayers who are engaged in a particular activity on or over the continental shelf. In this article, I will explore certain features of the US continental shelf definition of the United States that distinguishes it from any other tax provision in the Internal Revenue Code (IRC).
Definition of the US Continental Shelf
For the purposes of the US income tax, the IRC § 638(1) states that the United States “when used in a geographical sense includes the seabed and subsoil of those submarine areas which are adjacent to the territorial waters of the United States and over which the United States has exclusive rights, in accordance with international law, with respect to the exploration and exploitation of natural resources.” The opening clause of IRC § 638 specifically states that this definition of the United States applies only to the activities “with respect to mines, oil and gas wells, and other natural deposits.”
Analysis of the Definition of the US Continental Shelf
Two aspects need to be noted with respect to the definition above. First, the reference to international tax law means that the US government considers 200 miles of land underneath the ocean as its territory (the so-called “Exclusive Economic Zone” or “EEZ”). An interesting assumption that underlies IRC § 638 is that the continental shelf and the EEZ are the same.
Second, I want to emphasize that this is the definition that is tied to land only, not the water above the land – even more precisely, to certain activities on the ocean’s floor rather than in the water. This is a highly important aspect of IRC § 638, because it produces interesting results.
On the one hand, anyone (including foreign vessels and foreign contractors) drilling or exploring oil in the US continental shelf is considered to be engaged in a trade or business in the United States, which subjects these individuals and companies to US income tax. This also means that US tax withholding needs to be done with respect to foreign contractors. Moreover, even personal property (located over the US continental shelf) of a taxpayer engaged in the drilling or the exploration of the US continental shelf would most likely be classified as US personal property within the meaning of IRC § 956.
On the other hand, fishing in a boat in the same zone will not be considered as an activity within the United States, because it is not linked to mines, oil and gas wells, and other natural deposits.
This means that the application of the US Continental Shelf’s definition of the United States depends on the activity of the taxpayer, not just his location.
US Continental Shelf Rules and Foreign Countries
There is one more interesting aspect of the US continental shelf definition of the United States: its application to foreign countries. The first part of IRC § 638(2) states that the same definition of the continental shelf will also apply to foreign countries – i.e. the seabed and subsoil adjacent to the foreign country or possession and over which the country has EEZ rights.
At the end, however, IRC § 638(2) contains an interesting limitation: “ but this paragraph shall apply in the case of a foreign country only if it exercises, directly or indirectly, taxing jurisdiction with respect to such exploration or exploitation.” In other words, if a foreign country exercises its taxing jurisdiction over the continental shelf, then it is considered to be part of a foreign country. Otherwise, it will be considered as “international waters” (since it is also outside of the US continental shelf).

The definition of the United States in the context of the US continental shelf is just one of many examples of the enormous complexity of US tax laws. While even US citizens with domestic assets only have to struggle with these issues, the complexity of US tax laws is multiplied numerous times when one deals with a foreign individual/company or even US taxpayers with foreign assets. It is just too easy to get yourself into trouble.
