Home Office vs. Co-working Space: Which Expense Wins at Tax Time?
Comparing the real after-tax cost of a home office deduction versus a co-working membership for Canadian freelancers — the math might surprise you.

A co-working membership is 100% deductible as a business expense. A home office deduction gives you a percentage of your home costs based on your workspace proportion. The question is: which produces a larger actual deduction — and which one reflects your real working situation?
Home Office: The Math
If your office is 10% of your home's square footage, you can deduct 10% of rent, utilities, insurance, and property taxes. For a freelancer paying $2,400/month rent with $200/month in utilities, that's roughly $312/year in deductions — before you factor in internet and any workspace-specific costs. The deduction scales with home cost, so owners with mortgages, high property taxes, and large homes benefit most.
Co-working Space: The Math
A co-working membership at $300–$600/month is fully deductible as rent on your T2125. That's $3,600–$7,200/year in deductions — far larger than most home office calculations. The trade-off is that you're paying for the co-working space on top of your home costs, so the net cost is higher even accounting for the tax savings.
The home office deduction is not an either/or choice with co-working. If you use both — working from home most days and the co-working space occasionally — you can potentially claim both, proportionally to actual usage. Document which days you use each location.
