Home office deductions for incorporated owners: what the corporation can and can’t pay for

“My business runs out of my house — can the corporation just pay for my home office?” Incorporated owners in Maple Ridge and the Fraser Valley ask it often; the answer is yes, but not as most assume. Once incorporated, you are usually an employee of your company, which changes the rules. Here is what qualifies.

Home business tax deductions for an incorporated owner run through the corporation, not the personal return.

Whether the corporation reimburses you or pays you rent decides how it is taxed at both ends. Ask which fits your set-up.

Employee of your own corporation vs sole proprietor

A sole proprietor deducts these costs against business income if the space is the main place of business, or used only for business and regularly for client meetings. The claim cannot create a loss but carries forward. Vehicles: see the company car taxable benefit. For a sole proprietor, the business-use-of-home expenses CRA allows are deducted against business income; an incorporated owner follows the stricter employment rules set out next.

An incorporated owner is an employee, so the home office is an employment expense. To claim it personally, you must be required to keep the workspace, hold a signed Form T2200, and either work there mainly (more than half the time) or use it only for work and regularly for in-person client meetings. The claim cannot exceed your remaining employment income.

Reasonable rent-to-corporation arrangements

Alternatively, the corporation can reimburse a reasonable, documented share of home costs under an accountable plan, often the cleanest route. Or you rent part of the home to it: it deducts the rent, and you report rental income, offsetting related costs. Two cautions:

The rent must be reasonable, reflecting the space and fair value. And you should generally not claim capital cost allowance on your home, as it can compromise the principal-residence exemption on sale. Structure these arrangements with an accountant.

Home office tax deduction: which expenses qualify

Either way, only the business-use portion counts, usually by floor area. That covers a share of heat, electricity, insurance, maintenance and, depending on the arrangement, rent or mortgage interest and property tax. Personal use never qualifies, and costs the corporation reimbursed cannot be claimed again. Keep the split defensible and consistent.

The PSB overlay for single-client consultants

If your corporation mainly provides your services to one client you would otherwise work for as an employee, it may be a personal services business (PSB), which loses most deductions and pays a higher rate, a bigger risk than any home-office claim. See personal services business rules in Canada for the tests.

The CCA caution is a change-in-use issue: claiming CCA, making structural changes or using a large share of the home can make that part income-producing property. See the change in use rules for property.

Records the CRA asks for

Keep a signed T2200 for an employment claim, the business-use calculation, and receipts; if you rent to the corporation, a written agreement and rent records. File them with your personal tax records; in a CRA review, they decide whether the deduction stands. The same applies to cellphone and internet costs the corporation pays, with their own benefit rules. Those records are what back up the home business expenses CRA may ask about, whichever route the corporation uses.

However the arrangement is structured, the corporation only gets the deduction if the payment is supported. The guide to owner reimbursements and what the CRA expects covers the documentation side.

The bottom line

Yes, your corporation can pay for your home office, on the CRA’s terms: a T2200, a reasonable split, and care with rent and CCA. A Maple Ridge small business accountant can set it up and avoid the principal-residence and PSB traps.
