Short-term rental taxes in Canada have become a minefield in the last two years. If you host on Airbnb, Vrbo, or any booking platform, the tax rules changed in ways that can cost you real money: denied deductions, platforms reporting your income straight to the CRA, and sales tax obligations that start sooner than most hosts expect. Here is how the rules actually work in 2026, and the traps to avoid.
What counts as a short-term rental for tax purposes
For federal income tax purposes, the CRA defines a short-term rental as a residential property rented or offered for rent for a period of less than 90 consecutive days. That covers houses, condos, cottages, and trailers alike. Your city or province may use a different definition (Toronto counts anything under 28 days, for example), but the CRA’s 90-day line is what decides how the income tax rules apply to you.
All rental income must be reported on your tax return, no matter how little you earn. There is no minimum threshold. Rental income goes on Form T776, Statement of Real Estate Rentals (lines 12599 and 12600). If your short-term rental activity starts looking like a full-time operation with substantial services (daily cleaning, meals, concierge), the CRA may treat it as business income instead, reported on Form T2125. Either way, it is taxable.
The expense-denial rule: non-compliant rentals lose every deduction
This is the rule that has bitten the most hosts. Effective for taxation years after 2023, section 67.7 of the Income Tax Act denies ALL income tax deductions for a “non-compliant short-term rental.” Mortgage interest, property taxes, insurance, utilities, platform fees: none of it is deductible if the rental is non-compliant.
A rental is non-compliant if it sits somewhere the province or municipality does not permit short-term rentals, or if you have not met the registration, licence, or permit requirements that apply at that location. Toronto, Vancouver, Ottawa, and Montreal restrict short-term rentals to the host’s principal residence, for instance. Operating an investment condo as a short-term rental in those cities makes it non-compliant for this rule, and every dollar of expenses becomes non-deductible.
There are two details that make this rule nastier than most. First, the CRA gets an unlimited reassessment period for these denials. Normally the CRA has three years to reassess; for non-compliant rental expenses it can come back at any time. Second, there was transitional relief for the 2024 taxation year: a rental that was compliant by December 31, 2024 was deemed compliant for all of 2024. That window is closed now.
Bottom line: before you deduct a single expense, confirm your rental is fully licensed and permitted where it operates. A licence fee costs a few hundred dollars. Losing every deduction on tens of thousands of rental income costs far more.
The CRA already knows your income: platform reporting rules
If you are counting on the CRA not noticing your Airbnb income, stop. Since January 1, 2024, the Reporting Rules for Digital Platform Operators (Part XX of the Income Tax Act) require platforms to collect host information and report it to the CRA. The first reporting period was calendar 2024, with reports due by January 31, 2025, and it is annual from there.
Platforms report your name, address, tax identification number (your SIN or business number), the total paid or credited to you by calendar quarter, and for property rentals the address of each listing and the number of days each property was rented. You get a copy of what was reported by January 31 each year. The CRA compares that against your return.
This is the same pattern we describe in our guide to what triggers a CRA audit: the riskiest returns are the ones where a third party has already told the CRA a number and your return says something different. Report every payout, even small amounts.
Short-term rental taxes and GST/HST: the $30,000 threshold
Long-term residential rentals are GST/HST-exempt. Short-term rentals are not: stays of fewer than 30 days are taxable supplies. That means GST/HST applies to the nightly rate and any mandatory fees like cleaning charges.
You must register for GST/HST once your total taxable supplies exceed $30,000 over four consecutive calendar quarters. In Ontario that is 13% HST on your guests’ bills, which you collect and remit with regular returns. Below the threshold you can still register voluntarily, which lets you claim input tax credits on your expenses. Once you are registered, give the platform your GST/HST number: registered hosts collect and remit themselves, and the platform stops doing it on their behalf.
Here is what surprises hosts: if you are not registered, the booking platform is deemed to be the supplier of the accommodation and must register, collect, and remit the GST/HST on your bookings. So the tax is being charged either way. The difference is whether you control it (and claim your input tax credits) or the platform does.
One more trap: if you convert a home that was used mostly as a short-term rental and later sell it, the sale can be subject to GST/HST on the fair market value under the change-in-use rules, even if you were never registered. Get advice before selling a property that was used heavily as a short-term rental.
The principal residence and CCA traps
Renting out part of your own home can still leave your principal residence exemption intact, but only if you meet the CRA’s conditions: the rental portion must not be structurally separated (no separate entrance or self-contained unit), you must not claim capital cost allowance (CCA) on it, the rental use must be ancillary to your own residential use, and the home must remain primarily your residence.
Claiming CCA on your home is the classic trap. It gives you a deduction now but permanently denies the principal residence exemption on the rented portion when you sell, which can be a far bigger bill later. If you already claimed CCA, talk to a professional before selling. And if you have a prior-year tax problem of any kind, the CRA voluntary disclosure program is often a cheaper way to fix it than waiting for the CRA to find it.
Local taxes and licences you still have to handle
Federal tax is only part of the picture. Cities like Toronto and Ottawa impose a Municipal Accommodation Tax on short-term stays, which you must collect from guests and remit to the municipality on top of GST/HST. Registration and licensing fees are separate from taxes and vary widely: Toronto requires a short-term rental operator licence, and in British Columbia hosts register in a provincial registry.
Keep a compliance folder: your licence or registration, platform payout statements, booking calendars showing rental days versus personal-use days, and every receipt for expenses. The CRA expects six years of records, and for a short-term rental the rental-day calendar is what proves both your deductions and your compliance status.
The short-term rental taxes checklist
Before you list, or if you are already listing, work through this: (1) confirm your city permits short-term rentals at your address and get the required licence or registration; (2) report every dollar of platform income on Form T776; (3) track your taxable supplies and register for GST/HST before you cross $30,000; (4) if you are in Ontario, remember the 13% HST and any municipal accommodation tax; (5) do not claim CCA on a home you want to keep principal-residence-exempt; and (6) never deduct expenses on a non-compliant rental, because section 67.7 denies them and the reassessment clock never runs out.
