Who does this apply to?
If you are a Canadian resident who derives an income effectively connected* to any business or trade in the US through your Canadian corporation, that income will be subject to US tax filing and in some cases tax liability. This holds true for both employment and personal services rendered by employees of a Canadian corporation in the US.
*Effectively connected income: This income usually includes salary and business related income connected to services provided in the US. There are other types of income that are also considered effectively connected income such as:
- Royalties received on foreign property that are connected to business or trade in the US
- Product sales made to a foreign country from the US
- Profit or loss as a result of sale of US property or its shares
Canada-US Tax Treaty Deductions
Depending on whether your income is derived from a business/trade in the US through a Permanent Establishment (PE) or not, you will be allowed to avail deductions on your US tax liability. Canadian residents are taxable only if their business income has a PE in the US connected to it. If they are deemed to not have a PE, Canadians still have to file their US tax return (including world income) but can claim deductions on their liability as per the Canada-US tax treaty.
Determining if your business/trade has a PE:
In the framework of the treaty, the following criteria determine if a Canadian service provider has a PE:
- A PE is a fixed location through which the non-resident conducts their business in the US. Factories, offices, management premises, etc are examples of locations considered PE
- During any 12 month period:
- if an individual is present in the US for 183 days or longer and
- 50% of their total business revenue is comprised of revenue generated as a result of their service in the US
- During any 12 month period:
- If your business provides service for 183 days or longer
- service has been rendered for a project or connected projects involving a client who is US resident or has a PE through which your business has been conducted
Note: According to the treaty, locations used for purposes such as storage, delivery and maintenance, purchase of inventory, advertising etc., are not considered as PE.

US Withholding Tax Filing:
For the US to determine the amount of Withholding tax to be paid for your income, your status as to whether you are a US or foreign person must be ascertained. This can be done by your clients by them asking you to fill Form W-8 (W-8BEN, W-8BEN-E, etc). If you do not fill these forms, IRS reserves the right to deduct 30% withholding tax from your business income.
