Note: The flat rate method is simpler and requires no receipts. The detailed method requires you to keep receipts and records of all expenses. Employees must have a signed T2200 form from their employer to claim home office expenses.

How Home Office Deductions Work

The CRA offers two methods to claim home office expenses: The Flat Rate Method lets you claim $2 for each day you worked from home, up to $500 per year — no receipts required. The Detailed Method calculates your actual expenses (rent, utilities, internet, etc.) multiplied by the percentage of your home used for work.

Employees need a signed T2200 form from their employer to use the detailed method. Self-employed individuals report expenses on T2125 and can also deduct mortgage interest and property taxes — something employees cannot claim.

Disclaimer: This calculator provides estimates for informational purposes only. The flat rate method has specific eligibility requirements — you must have worked from home due to COVID-19 or employer requirements. Eligible expenses and rules may change. Keep all receipts and records if using the detailed method. Consult a tax professional or refer to CRA guidelines for your specific situation.
