The single most important difference
United States: Qualifying self-employed taxpayers can claim business use of home. Most ordinary W-2 employees cannot deduct unreimbursed home-office costs on their federal return under current law.
Canada: Eligible employees can claim certain work-from-home expenses using the detailed method when they meet CRA conditions and keep a completed Form T2200. Self-employed Canadians use the separate business-use-of-home rules.

Calculation methods compared
US actual method
- Use a reasonable business percentage of the home
- Square footage is the most common method; a room-count method can also be reasonable if rooms are about the same size
- Apply the percentage to eligible indirect home costs on Form 8829
Canada
- A designated room generally uses the workspace area compared with the finished area of the home
- For a common/shared space, CRA also adjusts for the hours the space is used for work
- For example, a room that is 14% of the home and used 40 hours out of 168 hours in a week has an employment-use percentage of about 3.33%
Example: Same workspace, two different outcomes
Scenario: employee working from home at a dining-area workspace that is 10% of the home
- In the US: An ordinary W-2 employee generally has no federal home-office deduction; the shared personal use would also fail the normal exclusive-use rule
- In Canada: If the employee otherwise qualifies and uses the common space 40 hours a week, the workspace percentage is 10% × (40 ÷ 168) = 2.38% of eligible costs for the qualifying period
The Canadian calculation for a common space reflects both the area and the amount of time it is used for employment.
What records to keep
United States:
- Workspace measurements or other support for the business percentage
- Records for actual home expenses claimed on Form 8829
- Notes showing regular and exclusive business use where required
Canada — employees:
- Completed Form T2200 from the employer
- Form T777 and supporting expense records
- Workspace measurements and, for common space, support for work hours used in the calculation
Canada — self-employed:
- Records supporting the T2125 business-use-of-home calculation and eligible household costs
