Home Office Expenses as an Employee: What Changed for 2026?

If you're an employee who works from home in 2026, you may be able to claim certain home office expenses on your tax return, but the rules are stricter than they are for self-employed workers. Employees can only claim expenses directly related to earning employment income, and only if their employer required them to work from home and did not reimburse those costs. Unlike the self-employed, salaried workers cannot claim rent, mortgage interest, or property taxes, and must meet specific CRA conditions to qualify for any deduction at all. The Canada Revenue Agency makes a clear distinction between employees and self-employed individuals when it comes to home office deductions. As an employee, this CRA rule may apply to you if all three of these conditions are met: - Your employer required you to work from home as a condition of employment - Your employer did not provide an allowance or reimbursement for home office expenses - You need the workspace to earn your employment income If any of these conditions are not met, you generally cannot claim home office expenses, even if you choose to work from home part of the week.

Frequently Asked Questions

Can I claim home office expenses if I work from home just 2 days a week?

No. Your employer must require you to work from home as a condition of your job, not simply permit it. If working from home is optional or only part-time by choice, you don't qualify, even if you have a dedicated desk at home. The CRA looks at whether the employer mandated the arrangement, not how often you use your home office.

My employer gives me a $100 monthly home office allowance. Can I still claim expenses?

No. If your employer provides any allowance or reimbursement for home office costs, you don't qualify to claim additional expenses on your tax return. The CRA rule requires that you receive no reimbursement at all. You should claim the allowance as employment income instead.

What if I buy a desk, chair, or computer for my home office?

As an employee, you cannot deduct furniture or computer purchases. The self-employed can claim these items under capital cost allowance, but employees are restricted to small supplies and direct expenses only. If your employer requires specific equipment, ask whether they will provide or reimburse it.

Do I need receipts if I claim home office expenses?

Yes. You must keep receipts and detailed records for all expenses you claim. The CRA may request documentation during an audit. Without receipts, you risk having your claim denied and potentially facing penalties. Use a simple spreadsheet to track dates, amounts, and categories.

Can I claim my mortgage interest or property taxes as an employee?

No. Employees cannot claim mortgage interest, property taxes, rent, or home insurance, regardless of how much you use your home office. These are reserved for self-employed individuals in very limited situations. As an employee, you're restricted to supplies, utilities (proportional), internet, and telephone expenses only.

Steps

  1. Confirm you meet the CRA eligibility test: Verify that all three conditions apply: your employer required (not permitted) you to work from home, you received no allowance or reimbursement, and you need the space to earn employment income. Check your employment contract or ask HR if you're unsure.
  2. Gather receipts and invoices for eligible expenses: Collect receipts for office supplies, internet, telephone, and utility bills. Organize them by category and date. If claiming a portion of internet or utilities, calculate the percentage of your home or time used for work.
  3. Calculate your deductible expenses for the year: Add up all eligible expenses (supplies, internet portion, telephone portion, utility portion). Document the calculation so you can explain it to the CRA if needed. Keep a simple spreadsheet with running totals.
  4. Complete the home office section of your T1 General form: On line 22900 of your T1 General tax return (form 1000-S), enter your total home office expenses. You may be asked to attach a detailed breakdown, so have your calculations and receipts ready.
  5. File your tax return and keep records for 6 years: Submit your return with the home office expenses included. Store all receipts, invoices, and documentation in a safe place for a minimum of six years, as the CRA may request them for audit purposes.
