What employees can still deduct for a home office

During the pandemic years, millions of employees claimed a home office deduction with almost no paperwork: a flat amount per day worked from home, up to a cap. Many assume something similar still exists. It does not. But the deduction itself did not disappear. It went back to the rules that applied before, which are stricter, need your employer’s signature and take an evening with your household bills.

For employees who genuinely work from home under their employment terms, the claim can still be worthwhile. Here is how it works.

The shortcut that ended

The CRA’s guidance is explicit: the temporary flat rate method was available for 2020, 2021 and 2022 and does not apply to the 2023 and later tax years. Since then, employees claim the employment-use portion of actual amounts they paid, a calculation the CRA calls the detailed method. The deduction is claimed on line 22900 of the return, as other employment expenses.

Because it is a deduction rather than a credit, it lowers taxable income and saves tax at your marginal rate, explained in our file on 2026 brackets.

The two conditions

According to the CRA’s Employment Expenses guide, a salaried employee can deduct work-space-in-the-home expenses only if one of these applies:

• the work space is where you mainly do your work: more than 50% of the time, for a period of at least four consecutive weeks; or
• you use the space only to earn employment income, and on a regular and continuous basis for meeting clients, customers or other people in the course of your work.

In addition, your employment contract must require you to pay the expenses, and your employer must not reimburse them.

The form only your employer can sign

The key document is Form T2200, Declaration of Conditions of Employment. Your employer completes and signs it to confirm that your contract requires you to pay these expenses. You do not send it with your return, but you must keep it in case the CRA asks. Without a T2200, there is no claim, however much of the week you spend at the kitchen table.

The simplified T2200S used for the flat-rate years no longer applies. If your employer has not offered a T2200, you can ask for one; whether they sign it depends on whether your terms of employment actually require you to cover the costs.

Working out the share of the home

The claim is the employment-use share of eligible costs. The CRA’s method starts with area: the work space divided by the total finished area of the home. If the space is a separate room used only for work, that percentage is the share. If the space is shared with family life, such as a corner of the dining room, the area share is then multiplied by the hours it is used for work out of the 168 hours in a week.

What a salaried employee can claim

The Employment Expenses guide lists the employment-use share of:

• electricity, heating and maintenance;
• rent, if you rent your home;
• reasonable monthly home internet access fees.

It also states what a salaried employee cannot deduct: mortgage interest, property taxes, home insurance or capital cost allowance. Furniture and equipment are capital purchases, not work-space expenses. Office supplies and certain phone costs are separate items with their own rules.

One home office, worked through

A tenant uses a spare room of 12 m² in an apartment of 120 m² only for work, more than half of the time, under a contract requiring them to pay the costs and with a signed T2200.

Had the same space been a dining corner used 42 hours a week, the area share would be multiplied by 42 ÷ 168 = 25%, and the rent and utility lines would be a quarter of what is shown.

Homeowners and commission employees

A salaried employee who owns their home can claim utilities and maintenance, but not mortgage interest, property taxes or home insurance, so homeowners’ claims are usually smaller than tenants’. Employees paid by commission can also deduct the work share of property taxes and home insurance, as long as they relate to earning commission income. Neither group can deduct mortgage interest or capital cost allowance.

The limit, and carrying forward

The deduction cannot create or increase a loss from employment: it is limited to employment income left after other employment expenses. Amounts that could not be deducted can be carried forward to a later year. The claim is made on Form T777S, or on Form T777 for employees with other employment expenses, with the result on line 22900.

One practical point: the claim belongs to the year the costs were paid, and a T2200 covers a particular year. An employee who worked from home for only part of the year, for example after changing jobs in the summer, claims only the expenses for the period the conditions were met, and needs a T2200 from the employer for that period.

What to check

If a new job also meant moving house, see when moving expenses can be deducted.
