How to Claim Home Office Expenses in Canada 2026: CRA Rules for Remote Workers
2026 Key Facts — Home Office Expenses, Canada
- COVID flat-rate method ($2/day): available for 2020–2022 only — EXPIRED
- Employees (2026): must have Form T2200 signed by employer; use T777 to calculate deduction
- Self-employed: deduct workspace expenses proportionate to square footage used exclusively for business
- Home office deduction cannot create a business loss — limited to net business income
- Eligible for employees: rent, utilities, internet, maintenance (but NOT mortgage interest unless commission-based)
- Commission employees: additionally eligible for mortgage interest, property taxes, home insurance
Home office expense deductions were simplified during COVID but have returned to their pre-pandemic rules for 2023 and beyond. For 2026, both employees and self-employed Canadians must use the detailed method — no more $2/day flat rate.
Can employees claim home office expenses in 2026 without a T2200?
No. The COVID-era flat-rate method ended after the 2022 tax year. For 2026, employees must obtain a signed Form T2200 (Declaration of Conditions of Employment) from their employer confirming they were required to work from home and pay home office expenses not reimbursed by the employer. Without a T2200, no deduction is available.
What home office expenses can employees deduct in 2026?
Salaried employees (non-commission) can deduct: rent (not mortgage interest), electricity, heat, water, internet access fees, maintenance and minor repairs, and cleaning supplies — all proportionate to the workspace percentage. They cannot deduct mortgage interest, property taxes, or home insurance. Commission employees can deduct all of the above plus mortgage interest, property taxes, and home insurance.
How do self-employed Canadians calculate the home office deduction?
Self-employed individuals calculate: business-use percentage × total eligible home expenses. Business-use % = square footage of the dedicated workspace ÷ total home square footage. The workspace must be used exclusively and on a regular and continuous basis for earning business income. A kitchen table used occasionally fails this test; a dedicated office room passes. Eligible expenses include rent, mortgage interest, property taxes, utilities, home insurance, and maintenance.
Can the home office deduction create or increase a business loss?
No. The deduction is limited to net business income for the year. Unused amounts carry forward indefinitely — no expiry date — to be applied against future business income.
What records do I need to support a home office claim?
Required: Form T2200 (employees); floor plan or measurement records; all receipts for eligible expenses (utility bills, rent receipts, property tax bills, mortgage statements); and a calculation worksheet. CRA commonly audits home office claims — keep all documentation for the standard 6-year retention period.
Can I deduct internet costs as a home office expense?
Yes — internet access costs are an eligible home office expense for both employees and self-employed. The deduction is based on the same workspace percentage used for other expenses. Only the business-use portion is deductible where personal use is mixed.
