Estimate your deduction for home office expenses

This calculator lets you estimate the deduction you could claim for home office expenses, for example, in the context of teleworking.

Estimate the deduction for home office expenses

This calculator can help you fill in parts 2 and 5 of the Employment Expenses of Salaried Employees and Employees Who Earn Commissions form (TP‑59‑V), which is required to claim this deduction. The calculator does not cover other employment-related expenses, such as vehicle expenses.

To claim this deduction, you must work primarily from home (more than 50% of the time) and have your employer send you the General Employment Conditions form (TP‑64.3‑V).

To estimate your deduction, have your receipts for the various eligible expenses and the square footage of your office space relative to the square footage of your home (in square metres or square feet).

The amounts obtained using this calculator are estimates. The exact amounts will be determined when you file your income tax return, based on the expenses you claim and your specific work situation.

For more details on this deduction, see the guide Employment Expenses (IN‑118‑V).

Moving during the year

If you moved during the year, you must consider the expenses paid for each of your homes separately. We suggest that you use the calculator for each of the two situations and enter the sum of the results on form TP‑59‑V.

Example

Suppose that on July 1, you moved from a rented dwelling unit to a home that you purchased.

You can deduct the home office expenses in your rented dwelling unit, including rent, for the months in which you worked from home before July.

For the months in which you lived in the home you own, you must redo the calculation according to the new area of your workspace in relation to the size of your home. Moreover, the eligible expenses change since you cannot include mortgage payments and interest, whereas rent is eligible for tenants.
