Working from home has become normal for many Canadians. But the rules for claiming home office expenses on your tax return are not always clear, and they differ depending on whether you are an employee or self-employed.

Employees working from home

The temporary flat rate method that CRA introduced during COVID ($2/day, up to $500) ended after the 2022 tax year. For 2023 and beyond, employees must use the detailed method and need a signed T2200 (or T2200S) from their employer.

To qualify, you must meet one of these conditions:

  • Your home is where you mainly (more than 50% of the time) do your work, OR
  • You use a dedicated space in your home exclusively to earn employment income and meet clients regularly

If you qualify, you can deduct a portion of:

  • Rent (if you rent your home)
  • Electricity, Heat, Water
  • Internet access fees
  • Maintenance and minor repairs to the workspace

Employees CANNOT deduct: mortgage interest, property taxes, home insurance, or capital cost allowance (depreciation) on the home.

The deductible portion is based on the size of your workspace relative to the total home. If you use the space part-time for work, you must also prorate by the hours used.

Self-employed individuals working from home

Self-employed individuals have a broader list of deductible expenses on Form T2125:

  • Rent
  • Mortgage interest (not principal)
  • Property taxes
  • Home insurance
  • Utilities (electricity, heat, water)
  • Internet
  • Maintenance and repairs

Important rule: home office expenses cannot create or increase a business loss. If your business income is $5,000 and your home office expenses are $6,000, you can only claim $5,000. The unused $1,000 carries forward to a future year.

Capital cost allowance: proceed with caution

Self-employed individuals can technically claim CCA (depreciation) on the business-use portion of their home. But doing so can trigger a capital gain when you sell the house, even on a property that otherwise qualifies for the principal residence exemption. In most cases, claiming CCA on your home is not worth the risk. Skip it.

Record-keeping tips

  • Measure your workspace and total home area. Keep the measurements on file.
  • Save all utility bills, property tax statements, insurance documents, and mortgage statements.
  • If you use the space part-time, keep a log of hours used for work.
  • If you are an employee, make sure your employer signs Form T2200 each year.

Shared spaces

If you and your spouse both work from home and share a workspace, only one of you can claim it (or you split the claim). You cannot both claim the full percentage on the same space.
