Quick answer. Long-term residential rental (continuous occupancy of one month or more) is an EXEMPT supply under Canadian GST/HST rules — no GST charged, no registration required regardless of income level. Short-term rental (continuous occupancy of LESS than one month, including most Airbnb, VRBO, and Booking.com bookings) is a TAXABLE supply. If total worldwide taxable supplies (including short-term rental revenue plus any other taxable business) exceed $30,000 over any four consecutive calendar quarters OR in any single calendar quarter, the operator must register for GST/HST. Alberta has 5% GST (no provincial sales tax). Registration deadline: within 29 days of crossing the threshold. As of November 3, 2025, GST/HST registration is online-only through Business Registration Online (BRO) — phone registrations were discontinued. The $30,000 threshold has been in effect since July 1, 2021 for short-term accommodation. Under $20/day accommodation is exempt regardless. Since 2024, CRA can deny expenses AND CCA claims for unlicensed short-term rentals — so an unlicensed Calgary Airbnb operator loses BOTH the deductions (income tax) AND may face GST/HST assessment on gross bookings.

The Long-Term vs Short-Term Line
The GST/HST definition of short-term accommodation is: a residential complex or unit supplied for occupancy as a place of residence or lodging for a period of LESS THAN one month continuous occupancy. Continuous is the key word. A guest who books 3 separate stays of 7 nights each within the same month is 3 short-term stays, not 1 long-term stay. Practical implications for Calgary landlords:
- Traditional long-term unfurnished rental with 12-month lease: EXEMPT. No GST/HST at any revenue level.
- Medium-term furnished rental with 3-month lease: EXEMPT (one month or more).
- Airbnb weekend booking of 3 nights: TAXABLE.
- Corporate housing 45-day stay: EXEMPT (one month or more).
- Vacation rental 10-day stay: TAXABLE.
- Rooming house with individual monthly leases: EXEMPT (one month or more).
The under-$20-per-day exception: accommodation charged at $20 or less per day is exempt regardless of duration. This is not relevant to essentially any Calgary rental at market rates but is included for completeness.
The $30,000 Small Supplier Threshold
GST/HST registration is not required if the operator's total worldwide taxable supplies do not exceed $30,000 in any single calendar quarter or in the last four consecutive calendar quarters combined. Key features:
- Applies to WORLDWIDE taxable supplies including all businesses the operator conducts, not just short-term rental. If you run any other GST/HST-taxable business, the revenues combine toward the threshold.
- $30,000 is gross revenue before expenses.
- Cleaning fees for short-term stays COUNT toward the threshold.
- Long-term rental revenue (exempt supplies) does NOT count toward the threshold (exempt supplies never do).
- The threshold recalculates rolling: at any point during the year that trailing-4-quarter revenue crosses $30,000, registration is triggered.
The Two Threshold Tests
Test 1: Single Quarter
If any single calendar quarter's taxable supplies exceed $30,000, registration is triggered effective the day of the supply that pushed you over. No grace period; GST/HST applies from that specific day. This test primarily catches operators whose revenue is concentrated in Calgary's summer peak season.
Test 2: Four Consecutive Quarters
If the trailing four consecutive calendar quarters combined exceed $30,000, the operator remains a small supplier until the END of the month following the quarter in which the threshold was crossed. Registration is triggered effective the first taxable booking after that date. This test provides a small grace period compared to Test 1.
Registration Process (Online-Only Since November 2025)
Since November 3, 2025, GST/HST registration is available ONLY through the Business Registration Online (BRO) system on canada.ca. Phone registrations were discontinued. The process:
- Log into BRO with your CRA My Account or Represent a Client credentials.
- Complete the registration form with business name, address, effective date (the date you crossed the threshold), and reporting period (monthly, quarterly, or annual — typically annual for small operators).
- Submit and receive your GST/HST number (starts with 8, format XXXXXXXX RT0001).
- Registration must be completed within 29 days of the effective date.
What Registration Actually Requires
Once registered, the operator must:
- Charge 5% GST on all short-term accommodation bookings in Alberta (13% HST in Ontario, etc., depending on province of the property).
- Collect the GST from guests (add to nightly rate, cleaning fees, other taxable charges).
- Remit collected GST to CRA on the reporting period schedule (annual for most small operators, quarterly for mid-size, monthly for larger).
- Track and claim Input Tax Credits (ITCs) — GST paid on purchases for the STR business (cleaning supplies, linens, maintenance, professional fees, portion of insurance) can be reclaimed. This partially offsets the GST collected on bookings.
- File the GST/HST return (form GST34 for most; other forms for specific structures) by the return deadline.
The 2024+ Non-Compliant STR Penalty
Since 2024, CRA can deny both income tax expenses AND CCA claims from non-compliant short-term rentals. Non-compliant means: operating without the required municipal business licence, or operating in prohibited jurisdictions. For Calgary, the City requires a Short-Term Rental Business Licence under Business Licence Bylaw 32M98 (see our Calgary STR rules guide). An unlicensed Calgary Airbnb operator therefore:
- Loses ALL income tax deductions on the rental (taxable on gross, not net).
- May face GST/HST assessment on gross bookings if the $30,000 threshold was crossed (registration is legally required regardless of licensing status).
- Faces $100/slip NR4 penalties if a non-resident is involved.
- Faces potential Calgary Bylaw enforcement fines up to $10,000 per infraction.
The stack of penalties for unlicensed operation typically exceeds any conceivable STR profit by a wide margin. Calgary STR is a licensed business or it is a losing proposition.
Frequently Asked Questions
Do I need to register for GST if I only rent out my basement suite long-term?
No. Long-term residential rental (one month or more continuous occupancy) is exempt from GST/HST at any revenue level. No registration is required regardless of how much you earn.
If I switch my Airbnb to long-term rental mid-year, what happens to my GST registration?
You remain registered but your taxable supplies drop toward zero. You continue to file returns showing exempt supplies only. If you stay below the $30,000 threshold in taxable supplies over the following four consecutive quarters, you can apply to deregister. Consult your accountant on the deregistration timing.
Do platforms like Airbnb collect and remit GST on my behalf?
In some cases, yes. Since 2022, digital economy GST/HST rules require major short-term accommodation platforms to collect and remit GST/HST when the property owner is a non-registered small supplier. However, once you are registered, YOU are responsible for collection and remittance, and the platform typically stops handling GST on your bookings. Confirm the platform's treatment for your specific account.
How does the STR revenue on Airbnb count for the threshold?
Gross nightly rent plus cleaning fees plus any other taxable service charges before Airbnb's platform fee. The Airbnb platform fee itself is not included in your revenue for threshold purposes (it is Airbnb's revenue, not yours). But the guest pays the gross amount before platform deduction; your revenue for the threshold is that gross amount.
Does UrbanLease handle GST for STR properties it manages?
UrbanLease's core service is long-term rental management. For STR-specific management including GST collection and remittance, we typically refer to dedicated Calgary STR management specialists. Long-term rentals under UrbanLease management do not trigger GST obligations (exempt supplies). Property management services provided by PREP Realty.
Bottom Line
For traditional Calgary long-term residential rentals, GST/HST is a non-issue — rents are exempt at any revenue level. For Calgary short-term rentals (Airbnb, VRBO, etc.), GST becomes a mandatory compliance step at $30,000 annual revenue, with 29-day registration timing and online-only registration since November 2025. Combined with the 2024 CRA rule denying expenses and CCA to non-compliant STRs, unlicensed and unregistered Calgary STR operation is a losing after-tax strategy. If STR is your model, license with the City, register for GST at the threshold, and treat it as a small hospitality business. UrbanLease's long-term rental management is fully outside the GST/HST framework as exempt supplies. Property management services provided by PREP Realty.
