Can You Claim Home Office Expenses If You Work From Home Part-Time in Canada?

Yes, part-time remote workers may be able to claim home office expenses on their 2026 tax return, but the CRA has specific rules about how much time you must spend working from home and what counts as an eligible expense. Whether you're an employee working from home a few days per week or a self-employed person with a side business, the key is proving to the CRA that your home office is a regular workspace that directly generates income. This guide explains what the CRA considers eligible and how part-time work-from-home arrangements differ from full-time setups. There's no single "part-time" definition in CRA rules, but this principle applies: you must work from home on a regular and ongoing basis. The CRA doesn't specify a minimum number of hours per week or days per month, but your workspace should be essential to earning income. Part-time home office claims typically fall into two categories: - Employees working from home part-time: You're entitled to claim home office expenses only if your employer required you to work from home due to COVID-19 or ongoing workplace conditions. You'll need a signed T2200 form (Declaration of Conditions of Employment) from your employer.

Frequently Asked Questions

Do I need a T2200 form if I work from home part-time as an employee?

Yes, if you're an employee claiming home office expenses, your employer must complete and sign a T2200 form confirming that you were required to work from home. Without it, the CRA won't allow your claim, even if you spend significant time working remotely.

Can I claim home office expenses if I work from home by choice, not by employer requirement?

No, not as an employee. The CRA only allows employee home office claims when the employer required you to work from home. If you choose to work remotely, you cannot deduct home office expenses unless you're self-employed.

What's the minimum number of hours per week I need to work from home to claim expenses?

The CRA doesn't specify a minimum number of hours, but your home office must be used on a regular and ongoing basis to earn income. You should be able to show consistent use patterns (like a daily log or calendar) if audited.

Can I claim part of my mortgage as a home office expense?

No, you cannot deduct mortgage principal. However, if you itemize expenses using the detailed method, you can claim a proportional amount of your mortgage interest (not principal), property tax, insurance, and utilities based on your office space percentage.

Is the simplified $2 per square foot method better for part-time workers?

Often yes. The simplified method is faster, requires no receipts, and works well if you have modest home office space (under 300 square feet) and few large expenses. Compare it to the detailed method using the Home Office Deduction Calculator to see which saves you more tax.

Steps

1. Step 1: Verify your eligibility: If you're an employee, confirm your employer required you to work from home and obtain a signed T2200 form. If you're self-employed, confirm your home office is a regular workspace where you earn income. Part-time status doesn't disqualify you, but the work must be regular and ongoing.
2. Step 2: Measure your dedicated office space: Calculate the square footage of your home office using a tape measure. Measure only the dedicated workspace (desk area, filing cabinets, shelving), not hallways or shared spaces. Document with photos and keep measurements for CRA records.
3. Step 3: Choose your deduction method: Decide between the simplified method ($2 per square foot, no receipts) and the detailed method (track rent, utilities, tax, insurance, repairs). Calculate both scenarios using the Home Office Deduction Calculator to see which saves you more tax.
4. Step 4: Gather receipts and documentation: If using the simplified method, no receipts are needed. If using the detailed method, collect invoices for internet, utilities, home insurance, mortgage statements (for interest calculation), property tax notices, and receipts for office supplies and furniture. Keep a daily log showing hours worked from home.
5. Step 5: Calculate your deductible expenses: For the simplified method, multiply your office square footage by $2 (max $600). For the detailed method, calculate your home office percentage (office square footage divided by total home square footage) and apply it to eligible household expenses.
6. Step 6: Claim on your tax return: Enter your home office deduction on line 22900 (employees) or line 8231 (self-employed) of your tax return. Attach supporting documentation (T2200, receipts, photos, measurements) to your file. You don't submit these with your return, but keep them for six years in case of audit.
7. Step 7: File and maintain records: Submit your completed tax return with home office deduction claimed. Store all receipts, measurements, photos, and work logs for six years. If the CRA questions your claim, you'll need documentation to prove regular and ongoing home office use.
