Quick Answer

  1. If your short-term rental did not comply with applicable provincial or municipal registration, licensing, or permit requirements for the year, the Canada Revenue Agency (CRA) can deny the expenses you incurred to earn that rental income.
  2. The rule applies to rentals offered for fewer than 90 consecutive days and took effect on January 1, 2024, under section 67.7 of the Income Tax Act.
  3. If your property was non-compliant for only part of the year, CRA generally prorates the denied amount based on the number of days the rental was non-compliant.
  4. A short-term rental in a municipality that bans them outright is typically treated as non-compliant for the entire year.
  5. Hosts in Toronto, Ottawa, Mississauga, and Hamilton must each check their own municipal registration status, because provincial rules defer to the local by-law.

When Your Airbnb Becomes a CRA Problem

Picture a Toronto host who booked guests throughout 2025, collected roughly $45,000 in rental income, and assumed the cleaning fees, utilities, and portion of mortgage interest would offset most of the tax bill. The booking calendar looks healthy. The receipts folder is organized. One detail was missed: the city registration lapsed in March and was never renewed.

Under the federal rule that took effect in 2024, that single municipal gap can convert an ordinary rental year into a tax reassessment risk. The expenses are still real, the money still left the host's bank account, and yet the CRA can deny them for the days the rental was non-compliant. For many Ontario operators heading into winter bookings, the difference between a compliant and non-compliant year is thousands of dollars in deductions. The good news is that the compliance test is clear, and the remediation path is practical.

What "Non-Compliant" Means Under the New CRA Rule

A short-term rental is non-compliant when the property, for all or part of the year, did not meet the registration, licensing, or permit requirements of the province or municipality in which it operates. Non-compliance also arises when the rental is operated in a locale that prohibits short-term rentals outright. For the days a property is non-compliant, CRA may deny the related expenses under section 67.7 of the Income Tax Act.

A "short-term rental" for tax purposes is a residential property, or part of one, rented for periods of fewer than 90 consecutive days. Airbnb, VRBO, booking.com, and direct bookings all generally fall within this definition when the stay is short enough. The 90-day threshold is important, because it separates traditional long-term tenancies, which are not subject to this rule, from the Airbnb-style operations that are.

Where a property is non-compliant for only part of the year, CRA typically calculates a non-compliant amount: the portion of total rental expenses that corresponds to the non-compliant days. Those expenses are then denied on the tax return, even where the host would otherwise be fully entitled to claim them.

Quick Start: Pick Your Path

Different host profiles face different first actions. Use this grid to identify your path before reading further.

Individual filer
You rent one property occasionally (a cottage, a basement suite, or your principal residence on weekends). Confirm your municipal registration, then report net rental income on Form T776 with your T1.
Sole proprietor
You rent two or more short-term properties as your main income source without a corporation. The rule applies property by property, and you may need to report on Form T2125 depending on services provided.
Incorporated host
You hold your short-term rental inside a corporation. The denial rule applies at the corporate level, and the non-compliant amount reduces your corporation's deductible expenses on the T2 return.
Multi-unit operator
You operate four or more units, provide hotel-style services, or employ staff. Compliance exposure is higher because each unit is tested separately, and HST registration obligations may also be in play.

Whichever path applies, the sequence is the same: confirm municipal status, calculate exposure, correct the record, then file. If you are uncertain which category fits your situation, book a consultation with our team before filing season.

Compliant vs Non-Compliant: How the Numbers Change

A compliant and non-compliant host can earn the same gross rental income in the same year, but their tax outcomes diverge sharply. The non-compliant host loses the ability to deduct a portion, or all, of operating expenses, which increases taxable rental income and raises the tax owing at the host's marginal rate.

Consider two Toronto hosts, each with identical operations: $60,000 of gross short-term rental income and $24,000 of eligible expenses across cleaning, utilities, insurance, platform fees, and allocated mortgage interest. The compliant host reports $36,000 of net rental income. The non-compliant host, assumed to be non-compliant for the full year, reports the full $60,000 because every expense is denied under section 67.7.

At a combined Ontario marginal rate of roughly 29.65% in the middle brackets, that $24,000 swing in reported income can translate into several thousand dollars of additional tax. The host spent the same money either way. Only the compliance status changed. Our corporate and personal tax services can help model the impact for your specific bracket and reporting form.

Your Four-Step Compliance Roadmap

Most Ontario hosts can move from exposure to compliance with a focused review. The following four steps form the standard sequence we walk clients through before filing season.

  1. 1
    Confirm Your Rental ClassificationStart by checking whether your bookings are short-term for tax purposes. If every stay in the year was 90 consecutive days or more, the denial rule generally does not apply. If any stays were shorter, those days fall within the short-term rental definition and must be tested against municipal rules.
  2. 2
    Check Your Municipal RegistrationEach Ontario city sets its own short-term rental regime. Toronto requires operators to register and generally restricts rentals to the operator's principal residence. Ottawa uses a host-permit system with its own eligibility rules. Mississauga and Hamilton have each introduced licensing by-laws with distinct requirements. Visit your city's short-term rental page to confirm the current registration, licensing, and night-cap rules that apply to your property.
  3. 3
    Document Your Compliance DatesIf you were compliant for only part of the year, document the exact dates the property was registered and in good standing. Keep a copy of the municipal registration confirmation, the issue date, and any renewal notices. CRA calculates the non-compliant amount using the number of days the rental was non-compliant, so your records should clearly support the days you claim were compliant.
  4. 4
    Report Correctly on T776 or T2125Report short-term rental income either on Form T776 (Statement of Real Estate Rentals) or Form T2125 (Statement of Business or Professional Activities), depending on the level of services you provide to guests. Where expenses are denied under section 67.7, remove the non-compliant portion from your claimed deductions and keep a working paper showing how the amount was calculated. Our tax filing services can prepare both forms and ensure the compliance adjustments are supported.

Common Mistakes Ontario Hosts Make

These are the recurring issues we see in short-term rental files during audit reviews and year-end planning:

  • →Assuming a listing on Airbnb or VRBO creates a tax position on its own, without checking whether the municipality requires separate registration or licensing.
  • →Letting a municipal registration lapse mid-year and continuing to accept bookings, which creates a non-compliant period even where the registration is later renewed.
  • →Claiming all mortgage interest, property tax, and utilities as rental expenses without reducing the claim for personal-use days or for the non-compliant days.
  • →Operating a short-term rental in a municipality that prohibits them, then treating the property as compliant because guests still booked. Operating in a locale that bans short-term rentals typically makes the property non-compliant for the entire year.
  • →Misclassifying bookings of 89 days as long-term tenancies. The threshold is 90 consecutive days or more, so a single booking one day short can keep the full year within the short-term category.
  • →Failing to keep documentation of the registration issue date, which makes it harder to defend a partial-year compliant position if CRA requests support.
  • →Treating HST registration as unrelated. Hosts crossing the $30,000 small-supplier threshold for short-term accommodation may trigger a separate HST compliance obligation, which is often discovered in the same review.

Frequently Asked Questions

If my Airbnb doesn't have a municipal licence, can I still deduct my expenses?

Generally no. Under section 67.7 of the Income Tax Act, CRA can deny the expenses you incurred to earn short-term rental income for any days the property did not meet applicable municipal registration or licensing requirements. Getting compliant now does not retroactively restore deductions for earlier non-compliant periods.

When did the CRA rule on non-compliant short-term rentals take effect?

The rule took effect for expenses incurred on or after January 1, 2024. It was introduced in the federal Budget 2023 and enacted into law through subsequent legislation. The denial applies to the 2024 tax year and every tax year that follows.

What counts as a short-term rental for CRA purposes?

A short-term rental is a residential property, or part of one, rented for periods of fewer than 90 consecutive days. Airbnb, VRBO, booking.com, and direct bookings typically qualify where the stay is short enough. Traditional long-term tenancies of 90 consecutive days or more fall outside this rule.

Do I need to register my Airbnb in Toronto to claim deductions?

Yes, if the property is in Toronto, you generally need to be registered under the City of Toronto's short-term rental by-law for the days you want to claim as compliant. Toronto also restricts short-term rentals to the operator's principal residence. Confirm the current rules on the City of Toronto website before filing.

My property was non-compliant for only a few months. Are all my expenses denied?

Typically no. Where a property is non-compliant for part of the year, CRA calculates a prorated non-compliant amount based on the number of non-compliant days versus total rental days. The expenses attributable to the compliant days may still be deductible, provided you can document the compliant period.

Can I still deduct mortgage interest and property tax on a non-compliant rental?

Mortgage interest, property tax, insurance, utilities, and similar operating expenses are all generally caught by the denial rule for non-compliant days. CRA treats these as expenses incurred to earn the short-term rental income, so they may be denied in the same proportion as other operating costs.

Does the rule apply if my Airbnb is in a city that bans short-term rentals entirely?

Yes, and the consequence is typically more severe. A short-term rental operated in a municipality that prohibits such rentals is generally treated as non-compliant for the full year, which can lead to all related expenses being denied on your return.

How do I report short-term rental income on a T776 or a T2125?

Hosts who provide limited services typically use Form T776 (Statement of Real Estate Rentals). Hosts who provide hotel-style services such as daily cleaning, meals, or concierge may need to report on Form T2125 (Statement of Business or Professional Activities). The correct form depends on the services provided, not simply on the booking platform.

If I get compliant now, will CRA retroactively allow my 2024 or 2025 expenses?

No. Compliance is tested based on the days during which the rental actually met the applicable requirements. Registering a property in 2026 does not retroactively restore deductions for days in 2024 or 2025 when the property was non-compliant. The best time to fix status is before year-end.

What penalties apply if I claimed expenses I wasn't entitled to?

Where CRA reassesses a return and denies expenses, the additional tax owing is generally subject to arrears interest, and gross-negligence or other penalties may apply depending on the circumstances. A voluntary correction before CRA contacts you is typically treated more favourably than a reassessment prompted by a CRA review.
