Rental income reporting, pro-rated deductions for mixed personal/rental use, GST/HST registration thresholds, and the capital gains implications of cottage rentals
Renting out a Canadian cottage is one of the most popular ways to offset ownership costs — a well-located waterfront property can generate $20,000–$70,000 in rental income during peak summer season. But cottage rental income is fully taxable, the deduction rules for mixed-use properties are complex, and the decision to rent can affect your capital gains tax position when you eventually sell. This guide explains everything cottage owners need to know about the tax treatment of rental income in Canada.
All rental income from a Canadian cottage must be reported to the CRA on your T1 personal income tax return. There is no threshold below which rental income is exempt — even $1,000 in cottage rental must be declared. The income is reported on Form T776 (Statement of Real Estate Rentals) and flows onto your Schedule 4 and ultimately your T1 return.
Most cottage owners use the property personally for part of the year and rent it out for the rest. The CRA requires that expenses be pro-rated based on the number of days the property was rented versus total days available. The formula is:
Deductible portion = (Rental days ÷ Total available days) × Total expense
| Expense Type | Deductibility | Notes |
|---|---|---|
| Property taxes | Pro-rated to rental days | Full year tax ÷ rental ratio |
| Insurance | Pro-rated to rental days | Confirm policy covers commercial use |
| Utilities (hydro, water, internet) | Pro-rated to rental days | Hydro directly traceable to rental may be fully deductible |
| Maintenance & repairs | Pro-rated (or fully if rental-specific) | New dock for rental guests = full deduction |
| Advertising / platform fees | 100% deductible | Airbnb/VRBO commissions, listing fees |
| Mortgage interest | Pro-rated to rental days | Interest only, not principal |
| Capital Cost Allowance (CCA) | Pro-rated — use with caution | Creates tax consequences on sale |
If your deductible cottage rental expenses exceed your rental income, you have a rental loss. The CRA applies the "reasonable expectation of profit" test — if your cottage is primarily a personal-use property with incidental rental, the CRA may deny the rental loss and refuse to allow it to offset your other income. A genuine commercial rental operation with a reasonable expectation of profit over time does not face this restriction.
Short-term cottage rentals (less than one month per booking) are subject to GST/HST once your total annual taxable supplies exceed $30,000. If your cottage rental revenue crosses this threshold, you must register for GST/HST and charge/remit tax on rental income. Long-term residential rentals (one month or more) are generally exempt from GST/HST.
