Alberta is the only Canadian province with no provincial sales tax. Residents and businesses pay only the federal 5% Goods and Services Tax (GST) administered by the Canada Revenue Agency (CRA) under Part IX of the Excise Tax Act. There is no provincial counterpart: no harmonized sales tax (HST), no provincial sales tax (PST), and no Quebec Sales Tax (QST). The total consumption tax rate on most purchases in Alberta is 5%.
This makes Alberta the lowest-tax jurisdiction in Canada for consumer purchases and a significant factor in large-item purchasing decisions involving vehicles, electronics, building materials, and business capital expenditures.
Quick Answer
The only sales tax in Alberta is the 5% federal GST. On a $500 purchase, GST is $25.00 and the total is $525.00. No additional provincial tax applies. Registered businesses collect 5% GST, claim input tax credits (ITCs) on eligible purchases, and remit the net amount to CRA.
Why Alberta Has No Provincial Sales Tax
Alberta has historically relied on resource royalties, primarily oil and natural gas, as an alternative revenue source, reducing the need for a broad-based consumption tax. The provincial government has maintained a no-PST policy as a deliberate economic positioning strategy. Alberta is also the only province with no provincial income surtax and operates under a flat provincial income tax rate (10% on the first $148,269 for 2026), further distinguishing it from other provinces.
There is no constitutional prohibition on Alberta introducing a PST. The province could adopt one through ordinary legislation. Several Alberta governments have studied the option but none has proceeded. The absence of PST is a provincial policy choice, not a constitutional constraint.
How GST Works in Alberta
The 5% GST applies to most goods and services supplied in Alberta, subject to the same zero-rated and exempt categories as all other Canadian provinces:
- Zero-rated (0%): Basic groceries, prescription drugs, most medical devices, international exports
- Exempt: Residential rent, health-care services, financial services (interest, insurance), most educational services, child care
- Taxable at 5%: Vehicles, electronics, clothing, restaurant meals, alcohol, hotel stays, professional services
GST Registration and ITCs
Businesses with total annual taxable supplies exceeding $30,000 must register for GST/HST with CRA. Small suppliers below this threshold may register voluntarily to claim ITCs. Registered businesses charge 5% GST on taxable sales and deduct GST paid on eligible business inputs from their remittance. If ITCs exceed GST collected (common for exporters and early-stage businesses), CRA issues a refund.
Worked Example
A Calgary contractor purchases $40,000 of building materials. GST at 5% = $2,000. The contractor charges their client $180,000 for the completed project. GST collected from client = $9,000. GST remittance = $9,000 collected minus $2,000 ITC = $7,000 net owing to CRA. The client (if a registered business using the building commercially) can in turn claim the $9,000 GST as an ITC.
Alberta GST vs Other Provinces
| Province/Territory | GST | Provincial | Total |
|---|---|---|---|
| Alberta | 5% | None | 5% |
| Northwest Territories | 5% | None | 5% |
| Yukon | 5% | None | 5% |
| Nunavut | 5% | None | 5% |
| British Columbia | 5% | 7% PST | 12% |
| Saskatchewan | 5% | 6% PST | 11% |
| Manitoba | 5% | 7% RST | 12% |
| Ontario | — | — | 13% HST |
| Quebec | — | — | 14.975% |
| Atlantic provinces | — | — | 15% HST |
The three territories also have no territorial sales tax, making Alberta and the territories the only no-PST jurisdictions in Canada.
Practical Impact
For a large discretionary purchase, the absence of PST creates meaningful cost differences. A $60,000 vehicle purchased in Alberta costs $63,000 including GST. The same vehicle purchased in BC costs $67,200 (5% GST + 10% PST on a vehicle in the $55,001-$55,999 band, or more at higher prices), in Ontario $67,800 (13% HST), and in Quebec $68,985 (5% GST + 9.975% QST). Cross-border shopping for large capital items is common, particularly along the AB-BC border.
Edge Cases and Rules
- Alberta residents who bring goods purchased out of province into Alberta do not owe any additional Alberta consumption tax. Alberta has no “use tax” obligation equivalent to BC PST’s self-assessment rule.
- Accommodation in Alberta is subject to 5% GST and, in some municipalities, a Tourism Levy (4% in Calgary and Edmonton, for example) charged separately by the municipality.
- Cannabis sales in Alberta are subject to GST plus a federally shared excise duty. No additional Alberta cannabis tax applies beyond the excise framework.
- If Alberta were to introduce a PST in the future, the province could request harmonization with the federal GST (joining the HST framework) or administer a separate PST as BC, Saskatchewan, and Manitoba do.
Frequently asked questions
- Does Alberta have a provincial sales tax?
- No. Alberta is the only Canadian province with no provincial sales tax. The only sales tax on purchases in Alberta is the federal 5% GST. There is no HST, no PST, and no QST.
- What is the total sales tax rate in Alberta?
- 5% — the federal GST only. No provincial consumption tax exists in Alberta as of 2026.
- How do I calculate GST in Alberta?
- Multiply the pre-tax price by 0.05. Add the result to the price. Example: $800 purchase: GST = $40; total = $840.
- Why doesn't Alberta have a provincial sales tax?
- Alberta has historically funded government services through oil and natural gas royalties rather than a broad consumption tax. The no-PST policy is a deliberate provincial policy choice, not a constitutional restriction. Alberta could introduce a PST through ordinary legislation.
- Do businesses in Alberta have to charge GST?
- Yes, if their taxable annual supplies exceed $30,000. Businesses above this threshold must register with CRA, collect 5% GST on taxable sales, and remit the net amount after input tax credits. Small suppliers under $30,000 may register voluntarily.
- What is exempt from GST in Alberta?
- The federal GST exemption list applies in Alberta: basic groceries, prescription drugs, most medical devices, residential rent, most health-care and financial services, and educational services are exempt or zero-rated. The full exemption list is in Schedule V and Schedule VI of the Excise Tax Act.
- Is Alberta cheaper for buying a car because of no PST?
- Yes. Vehicles purchased in Alberta are subject only to 5% GST. In provinces with PST or HST, combined rates range from 11% (Saskatchewan) to 15% (Atlantic provinces). For a $50,000 vehicle, the savings compared to Ontario (13% HST) is $4,000.
- Are there any other taxes on purchases in Alberta?
- Yes, a few targeted levies exist: a municipal Tourism Levy on hotel accommodation (4% in Calgary and Edmonton), a federally administered cannabis excise duty, and carbon-pricing charges embedded in fuel and natural gas prices. These are not PST.
- If I buy something in BC and bring it to Alberta, do I owe any Alberta tax?
- No. Alberta has no use-tax or self-assessment obligation for goods brought in from other provinces. You would have paid BC's GST+PST at point of purchase, and no further Alberta tax applies.
- Could Alberta introduce a PST in the future?
- Constitutionally, yes. Provincial sales taxes are within provincial legislative authority. Alberta could introduce PST through legislation. Multiple Alberta governments have studied the option but none has implemented it, citing competitive positioning and resource-revenue sufficiency.
- Is alcohol subject to any extra taxes in Alberta?
- Alcohol is subject to 5% GST and provincial markup through Alberta Gaming, Liquor and Cannabis (AGLC), which controls wholesale pricing. The AGLC markup functions as an embedded levy rather than a visible line-item tax.
