Yes, you can deduct home office expenses for 2026 if you meet the CRA’s conditions, but the rules depend on whether you are an employee or self-employed. Employees must use the detailed method, with Form T2200 signed by their employer, and claim on Form T777. Self-employed people claim business-use-of-home expenses on Form T2125.
The temporary flat rate method is gone; it only covered 2020 to 2022. This guide explains who qualifies, which expenses each group can claim, how to work out your work-space percentage, and the mistakes to avoid.

Key Takeaways
- Employees can only use the detailed method for 2026: a T2200 signed by the employer, Form T777, and the total on line 22900.
- To qualify as an employee, you must have been required to work from home, and either worked there more than 50% of the time for at least four consecutive weeks or used the space only for work and to meet clients regularly.
- Salaried employees can claim utilities, home internet access fees, maintenance and rent, but not mortgage interest. Commission employees can also claim home insurance and property taxes.
- Self-employed people claim on Form T2125 and can include a share of mortgage interest, property taxes, insurance and utilities, but the claim cannot create or increase a business loss.
- Use a reasonable basis, such as floor area, for the work-space percentage, and keep your bills and calculations in case the CRA asks.
Who can deduct home office expenses
Two groups can claim home office costs, under separate rules:
- Employees whose employer required them to work from home, using Form T2200 and Form T777.
- Self-employed people (sole proprietors and partners) whose home is their principal place of business, or who use the space only for the business and regularly meet clients there, using Form T2125.
If you work from home for your own corporation, the corporation is a separate taxpayer, so ask your accountant which approach fits. And whichever group you are in, the temporary flat rate method of $2 a day is no longer available: it applied only to 2020, 2021 and 2022.
Employees: the detailed method, T2200 and T777
You can claim work-space-in-the-home expenses for 2026 if all of these apply:
- your employer required you to work from home (a written or verbal agreement is enough);
- you worked from the home work space more than 50% of the time for at least four consecutive weeks, or you used it only for work and regularly met clients or customers there in person;
- your employer completed and signed Form T2200; and
- your employer did not reimburse the expenses.
What employees can claim
All employees can claim the work-use share of electricity, heat and water, the utilities part of condo fees, home internet access fees, maintenance and minor repairs, and rent for the home where you live. Commission employees can also claim home insurance, property taxes, and the lease of a cell phone, computer, laptop, tablet or fax machine.
No employee can claim mortgage interest or principal, capital cost allowance, internet connection fees, furniture, capital costs such as new windows or a furnace, or wall decorations. You list the expenses on Form T777 and enter the total on line 22900 of your return.
Your claim cannot be more than your employment income left after other employment expenses. Anything you cannot deduct carries forward to the next year.
Self-employed: business-use-of-home on Form T2125
If you are self-employed, you can deduct business-use-of-home expenses when the work space is your principal place of business, or when you use it only to earn business income and regularly meet clients, customers or patients there.
You can claim the business share of heat, electricity, home insurance, cleaning materials, maintenance, property taxes and mortgage interest. If you rent, you claim the business share of your rent and related expenses. The expenses go in Part 7 of Form T2125, with the total on line 9945.
- No business loss. The claim cannot be more than your net income from the business for the year. Unused amounts carry forward to later years, under the same conditions.
- Be careful with capital cost allowance. You can claim CCA on the business part of your home, but if you do, the capital gain and recapture rules apply to that part when you sell. Talk to your accountant before claiming it.
Self-employed people deduct their other business costs on the same form. Our guide to handling tax returns as a self-employed individual covers the rest of the return.
Employees vs self-employed: side by side
The two sets of rules differ most on ownership costs such as mortgage interest and property taxes.
| Rule | Employee | Self-employed |
|---|---|---|
| Forms | T2200 signed by the employer, plus T777 (line 22900) | T2125, Part 7 (line 9945) |
| When you qualify | Required to work from home, and either more than 50% of the time for 4 consecutive weeks or used only for work and to meet clients | Principal place of business, or used only for the business and regularly to meet clients |
| Utilities, maintenance and rent | Yes | Yes |
| Home insurance and property taxes | Commission employees only | Yes |
| Mortgage interest | No | Yes |
| Capital cost allowance on the home | No | Allowed, but affects the sale of your home |
| Limit | Employment income after other employment expenses; the rest carries forward | Net business income; the rest carries forward |

How to calculate your home office percentage
Use a reasonable basis. The CRA’s usual method is the area of the work space divided by the total finished area of your home, including hallways, bathrooms and kitchens.
If the space is also used for personal purposes, such as a dining table you clear each evening, you also have to reduce the claim to the share of hours it is used for work. The self-employed rules allow a similar hours-based approach.
Example
Say your office is 150 square feet in a home with 1,500 square feet of finished area, so 10% of the home, and it is used only for work.
- An employee who rents, with $24,000 of rent and $2,400 of heat, electricity and water for the year, could claim 10% of $26,400, or $2,640.
- A self-employed homeowner with $9,000 of mortgage interest, $4,500 of property taxes, $1,500 of home insurance and $3,000 of utilities could claim 10% of $18,000, or $1,800, as long as the business earned at least that much.
Other work-from-home costs: supplies, phone and vehicle
Some costs are claimed outside the work-space calculation.
- Supplies. If your employment contract required you to provide and pay for supplies, you can deduct items used directly in your work, such as stationery, stamps, toner and ink cartridges, but not items like briefcases or calculators.
- Cell phone. A salaried employee can claim a reasonable work-use share of a basic cell phone plan, if the work use is documented, but not the cost to connect or license the phone.
- Vehicle. If you drive for work, keep a logbook of business kilometres. Our guide to vehicle tax deductions covers the CRA rules.

Records and common mistakes
Keep the paperwork that supports your claim, and watch for these mistakes:
- Using the $2-a-day flat rate, which ended after 2022.
- Claiming without a signed T2200, or claiming expenses your employer reimbursed.
- Claiming mortgage interest as an employee, or property taxes and home insurance as a salaried employee.
- Overstating the work-space percentage, or treating a shared room as if it were used only for work.
- Claiming CCA on your home without understanding what happens when you sell.
Keep your bills, receipts, area calculation and T2200 in case the CRA asks for them; its general rule for business records is six years from the end of the tax year they relate to. Our article on what triggers a CRA audit explains other red flags.

Frequently Asked Questions
Can I still use the $2-a-day flat rate for home office expenses?
No. The temporary flat rate method only applied to the 2020, 2021 and 2022 tax years. For 2026, employees have to use the detailed method, which means a T2200 signed by your employer, your actual expenses, and Form T777. Self-employed people claim business-use-of-home expenses on Form T2125 instead.
Can I deduct mortgage interest for a home office?
Only if you are self-employed and meet the business-use-of-home conditions. Then you can claim the business share of mortgage interest, along with property taxes and home insurance. Employees cannot claim mortgage interest. Commission employees can claim home insurance and property taxes, but salaried employees cannot.
Do I need a T2200 if I only work from home part of the week?
Yes, if you want to claim as an employee. Your employer must complete and sign Form T2200, and you must meet the CRA’s conditions: you were required to work from home, and you worked there more than 50% of the time for at least four consecutive weeks, or used the space only for work and to meet clients.
What if my home office expenses are more than my income?
You cannot use them to create a loss. Employees can deduct work-space expenses only up to the employment income left after other employment expenses, and self-employed people only up to their net business income. In both cases, the unused amount carries forward and can be claimed in a later year under the same conditions.
Will claiming home office expenses affect the sale of my home?
The CRA’s warning is about capital cost allowance. If you are self-employed and claim CCA on the business part of your home, the capital gain and recapture rules apply to that part when you sell. That is why it is worth talking to your accountant before claiming CCA on your home.
