Employment Deductions (Canada, Remote). With a signed T2200, you can claim work-space-in-the-home expenses using the detailed method: a reasonable portion (by area/use) of rent, utilities, internet, and maintenance. Note: salaried employees generally cannot deduct furniture (the chair/monitor) as capital items, but supplies consumed for work may qualify. Keep the T2200, receipts, and a calculation of your workspace percentage for your T1 return.
