Allowed expenses include heat, electricity, light bulbs, cleaning materials, maintenance, etc. If the home is rented, a reasonable portion of the rent may be deducted. Mortgage interest and capital cost allowance may not be deducted.
Sales commission employees eligible to deduct work-space-in-home expenses may also deduct a reasonable portion of property taxes and home insurance.
CRA form T777, Statement of Employment Expenses, is used to calculate the amount of the work-space-in-home expenses allowed.
The work-space-in-home expenses can only be used to reduce employment income. They cannot be used to create or increase a loss from employment income. Any expenses in excess of the employment income can be carried forward to be used in the next tax year.
The work-space-in-home expenses will include any GST/HST or provincial sales taxes incurred. You may be eligible for a refund of the GST/HST included in the costs. See Employee and Partner GST/HST rebate on the GST/HST page.
Line 229 employment expenses can be entered in the "other deductions" line of the Canadian Tax and RRSP Savings Calculator.
