As per the US-Canada tax treaty, a Canadian resident earning self-employment income in the US, this income is exempt from US federal taxation (Note that this does not mean you are exempt from state taxation). This is strictly under the condition that this income was not generated through a Permanent establishment (PE) in the contracting state. While previously you would be required to file a US-Canada tax treaty based return under Article XIV – “Independent Personal services”, the definition of PE has been further clarified leading to change in procedure effective January 1st, 2008. The former PE criteria did not account for the amount of time spent or revenue generated as self-employment income. Let’s have a look at the treaty’s current definition:
Permanent Establishment
A Canadian resident is deemed to have a PE in the US if:
- they spent more than 183 days in the contracting state during which time more than 50% of their gross revenue was as a result of services rendered in that state.
(or)
- if their services were rendered for more than 183 days during any 12-consecutive month period with respect to a project.
Current Taxation
With this revision, the blank exemption of self-employment income (not generated through a PE) from US taxation regardless of revenue generated and time spent is now not applicable. The profits from these self-employed personal services henceforth termed “Business profits”, are now taxable by contracting states proportional to the amount of business activity. This is as per Article VII (“Business profits”) of the United States-Canada Income Tax Convention.
