Home Office Deduction in Canada for Remote Workers: What You Can Actually Claim

If you’ve been working from home — whether fully remote or on a hybrid schedule — you may be able to deduct a chunk of your household expenses from your taxable income. The CRA lets eligible employees claim a portion of rent, electricity, internet, and heat, but there are real conditions attached: your employer has to sign off on a form, your workspace has to meet a specific threshold, and you need to do the math yourself. Most remote workers either don’t know about this deduction or assume it’s too complicated to bother with. It usually isn’t.

Quick answer: Remote employees in Canada can claim home office expenses on Line 22900 using the detailed method, provided your employer signs a T2200 confirming you’re required to work from home. You can deduct a proportionate share of rent, electricity, internet, and heat based on your workspace’s share of your home’s total area.

Who qualifies for the home office deduction in Canada?

You qualify for the home office deduction if two conditions are met. First, you need a signed T2200 (Declaration of Conditions of Employment) from your employer — this is a one-page form confirming you were required to work from home and had to pay your own expenses. Second, your home workspace must either be the place where you do more than 50% of your work, or a space used exclusively and regularly to meet clients or customers.

If your company went remote or hybrid and you’ve been working from your apartment most of the week, you likely clear both hurdles. If you chose to work from home for convenience but had full access to an office, you’re on shakier ground. When in doubt, ask your HR department — they’ll know whether your setup qualifies, and most companies that allow remote work have a standard process for issuing T2200s by February or March.

What home expenses can you actually deduct?

The list of claimable expenses is more useful than most people expect. For salaried and hourly employees, eligible costs include:

• Rent — the portion corresponding to your workspace
• Electricity, heat, and water
• Internet access fees — the work-use portion
• Maintenance and minor repairs that relate to your workspace

Commission employees — those required to pay their own expenses and who earn commissions — can also claim property taxes and home insurance. Everyone else is limited to the list above.

What you cannot claim as an employee: mortgage interest, furniture, computer equipment, or any capital purchase (anything that lasts more than a year and holds lasting value). If you’re also running a side business, your home office deduction for employment income is completely separate from any business-use-of-home deduction you’d claim on your T2125 — mixing these up is one of the more common filing mistakes. Our guide to side hustle taxes in Canada covers the self-employed side in more detail.

Quick tip: Measure your dedicated workspace in square metres, then divide by your home’s total square metres. That percentage is what you apply to each eligible expense. A 9 m² home office in a 75 m² apartment = 12% of allowable costs.

How to calculate the deduction step by step

The math is straightforward once you have two numbers: your workspace percentage and your total eligible expenses for the year.

Workspace percentage: Measure the square footage (or metres) of the area you use for work and divide it by your home’s total interior area. If part of your workspace doubles as a guest room or dining room, the CRA expects you to account for that — typically by estimating a reasonable work-use fraction of that shared space.

Eligible expenses total: Add up your rent, electricity, internet, heating, and water bills for the year. Apply your workspace percentage to each. If you paid $21,600 in rent and your office takes up 12% of your home, the deductible portion is $2,592. Do the same for your other bills and add them together.

One constraint: your total home office deduction cannot exceed your net employment income for the year. If the number comes out larger than your income, you can carry the unused portion forward to a future tax year — it doesn’t just disappear. Report the final number on Line 22900 of your return, calculated on Form T777.

How the T2200 works and what to do with it

The T2200 is filled out and signed by your employer — not by you. You keep the original and do not submit it with your return, but you must have it on hand if the CRA ever asks to verify your claim. Ask your HR or payroll department as early in the year as possible; they don’t need to complete it before you file, but having it before tax season avoids last-minute scrambling.

The form itself is simple. It asks whether you were required to work from home, whether you received an allowance for home expenses, and what kinds of expenses you were required to pay. Your employer answers the questions — you take their answers and do your own expense tracking. Once you have the signed T2200, calculate your deduction using Form T777, enter the result on Line 22900, and file as usual.

Frequently Asked Questions

Do I need a T2200 to claim home office expenses in Canada?

Yes. For employees, a T2200 signed by your employer is required — there is no longer a simplified flat-rate option available for most tax years. Without the signed form, the CRA does not consider your home office expenses deductible. Most employers who allow remote work will sign one on request, though they’re not legally obligated to.

Can I claim my internet bill as a home office expense in Canada?

Yes, you can claim the work-use portion of your internet costs. Multiply your monthly internet bill by 12 to get the annual cost, then multiply that by your workspace percentage. Keep your invoices as supporting documents in case the CRA asks to verify your claim.

What if I’m hybrid — some days home, some days in the office?

You can still qualify if working from home accounts for more than 50% of the time you perform your employment duties. If you’re in the office two days a week and home three, you likely meet the threshold. The CRA may ask you to document your schedule, so keeping a simple log of where you worked each day is a smart move.

Can I claim a portion of my mortgage if I own my home?

No. Employees cannot deduct mortgage interest, property taxes (unless you’re a commission employee), or anything tied to the value or purchase of your home. You can still claim electricity, heat, internet, water, and maintenance — just nothing related to your mortgage or home ownership costs.

Where exactly do I report home office expenses on my tax return?

Home office expenses for employees go on Line 22900 (Other Employment Expenses). You calculate the amount using Form T777 (Statement of Employment Expenses) and enter the total on Line 22900 when filing. Keep your T2200 and all receipts filed at home — you don’t send them in, but the CRA can request them during a review.
