Canadian taxpayer's residency questioned based on "center of vital interest".

AuthorZink, Bill

A recent tax court decision (Powertex, TC Memo 1998-231), provides guidance on the U.S.-Canadian residency tiebreaker provisions.

Despite the amendments to Article IV of the U.S.-Canada treaty, and recent developments concerning green-card holders, this is an interesting case for Canadian southbounders.

There are two ways to attain U.S. residency--either to pass the substantial physical presence test (183-day rule) or to be lawfully admitted for permanent residence (green-card test). Once a person attains tax residency, it can be overridden by a tax residency treaty-tiebreaker provision.

In May, the taxpayer transported a boat he co-owned with his brother and docked it at the marina in Florida that serviced his girlfriend's apartment. The taxpayer obtained an insurance policy on the boat and listed his girlfriend's apartment as his address.

While in Florida, the taxpayer drove a company car and, in August, obtained a Florida driver's license that identified his address as his girlfriend's apartment.

During 1990, however, the taxpayer also shared an office with his brother at the family home in Canada. He maintained a room and kept personal belongings there, including two cars (both of which were registered in Montreal).

The taxpayer retained his Montreal driver's license and Canadian health insurance. He saw a...
