Home Office Deductions in BC: Employee and Self-Employed Rules
A spare room or shared workspace can support a home office deduction, but the tax rules depend on how you earn your income. Employees and self-employed business owners use different forms and cannot automatically claim the same expenses.
Whether you work from a townhouse in Langley, a condo in Burnaby or a home in Courtenay, start with your working arrangement and actual use of the space, not a standard percentage applied to every household bill.
Self-Employed Owners: Start With T2125
For a sole proprietor, the workspace must generally be your principal place of business, or be used exclusively to earn business income and regularly and continuously to meet clients, customers or patients. Occasional work at the kitchen table does not establish eligibility by itself.
Eligible business-use-of-home costs are reported through Form T2125. A corporation is a separate taxpayer, so an incorporated owner should review reimbursement, employment or rental arrangements rather than automatically using the sole-proprietor method.
Employees: T2200 and T777 Have Different Roles
Employees generally need an employer-completed T2200 and must meet the applicable work-from-home conditions. One route involves working from home more than 50% of the time for at least four consecutive weeks. An alternative involves exclusive employment use and regular, continuous meetings in the space.
The employee calculates eligible expenses on T777. The temporary flat-rate method and simplified pandemic-era forms should not be treated as the current default. See CRA’s employment expenses guide for the applicable year.
Which Costs Can You Claim?
Self-employed: A reasonable business portion of eligible rent, utilities, maintenance, insurance, property taxes and mortgage interest may qualify. Mortgage principal does not.
Salaried employees: Eligible costs can include a portion of rent and certain utilities, maintenance and home internet access. Mortgage interest, property taxes and home insurance generally do not qualify.
Commission employees: Additional costs such as property taxes and home insurance may qualify if the specific conditions and limits are met.
Business telephone costs and equipment need their own analysis. An item used at home is not automatically a workspace expense.
Use a Reasonable Space and Time Calculation
Measure the workspace and total relevant area. A dedicated 100-square-foot office in a 1,000-square-foot home gives a starting area ratio of 10%. Shared rooms also require a reasonable adjustment for personal use and time.
Keep bills, a floor-area calculation, dates of use and an explanation of your method. Separate periods if you moved or changed work arrangements during the year. Avoid double-counting reimbursed expenses or costs claimed by another household member.
Check Limits Before Claiming Depreciation
Workspace deductions generally cannot create or increase a loss from the relevant business or employment income; carryforwards have conditions. For self-employed owners, claiming capital cost allowance on the home can affect future sale and change-of-use treatment. Employees cannot deduct home depreciation as a workspace expense.
Review CRA’s business-use-of-home guidance before deciding what to claim.

Frequently Asked Questions
Does another office prevent a claim?
Not necessarily, but your home workspace still must meet the appropriate eligibility test. Having a desk at home alone is insufficient.
Will a reasonable percentage guarantee approval?
No. Both eligibility and the underlying expenses need support. A clear calculation makes the claim easier to explain.
