Alberta GST: 5%
Need to extract GST from a gross Alberta total? Use the TaxBackwards.ca reverse GST calculator.
Alberta is the only Canadian province with no provincial sales tax. The sole tax applied to most purchases is the 5% federal Goods and Services Tax (GST), administered by the Canada Revenue Agency. For every $105.00 paid in Alberta, $100.00 is the net consideration base and $5.00 is GST. Businesses registered for GST can claim the $5.00 as an Input Tax Credit.
How Alberta GST Reverse Calculation Works
To extract the net pre-tax amount from a gross total, divide by 1.05. To isolate the GST portion, multiply the net amount by 0.05 — or simply subtract the net from the gross.
Worked example 1: $105.00 gross ÷ 1.05 = $100.00 net. $105.00 − $100.00 = $5.00 GST. The $5.00 is the ITC-eligible amount for a GST-registered business.
Worked example 2: $210.00 gross ÷ 1.05 = $200.00 net. $210.00 − $200.00 = $10.00 GST.

What Is an Input Tax Credit (ITC)?
If your business is registered for GST with the CRA, the GST you paid on eligible business expenses is recoverable as an Input Tax Credit. The ITC reduces your net tax remittance to the CRA. Use the extracted GST amount from this calculator as your ITC-eligible figure, and verify eligibility against CRA guidelines before filing.

Alberta GST — Frequently Asked Questions
- What is the sales tax rate in Alberta?
- Alberta has no provincial sales tax. Only the 5% federal GST applies, making Alberta the lowest-tax province for consumer purchases in Canada. GST is administered by the Canada Revenue Agency.
- How do I calculate GST backwards from a total in Alberta?
- Divide the gross total by 1.05 to get the net pre-tax amount. Multiply the net by 0.05 to get the GST portion. Example: $105.00 ÷ 1.05 = $100.00 net; $100.00 × 0.05 = $5.00 GST.
- Can I claim Alberta GST as an Input Tax Credit?
- Yes. If your business is registered for GST with the CRA, GST paid on eligible business expenses is recoverable as an Input Tax Credit (ITC), reducing your net federal tax remittance to the CRA.
- What is exempt from GST in Alberta?
- Basic groceries, prescription drugs, most medical devices, residential rent, most financial services, and insurance premiums are either zero-rated or exempt from GST across all Canadian provinces including Alberta.
- Is there a provincial sales tax in Alberta?
- No. Alberta is the only province in Canada with no provincial sales tax — no PST, no HST, no RST. Only the 5% federal GST applies. However, Alberta charges a 4% tourism levy on hotel and short-term accommodation, which is separate from GST.
- Do I still need to register for GST if I operate in Alberta?
- Yes, if your taxable revenues exceed $30,000 over any four consecutive calendar quarters, you must register for GST with the CRA regardless of province. The absence of provincial tax in Alberta does not affect the federal GST registration threshold.
- Is GST charged on used car purchases in Alberta?
- When buying from a dealer, 5% GST applies. When buying from a private seller, no GST is charged — private vehicle sales are not subject to GST. Alberta is also the only province with no provincial vehicle tax, making it the lowest-tax province in Canada for vehicle purchases overall.
- What is the difference between zero-rated and exempt goods under GST?
- Zero-rated goods (such as basic groceries and prescription drugs) are taxed at 0% — businesses charge no GST but can still claim ITCs on related expenses. Exempt goods (such as most financial services and residential rent) have no GST and businesses cannot claim ITCs on related costs. The distinction matters for ITC eligibility on business inputs.
- Does the federal luxury tax apply in Alberta?
- Yes. The federal luxury tax applies across all provinces including Alberta. It applies to new passenger vehicles priced above $100,000 and new recreational boats and aircraft above certain thresholds. The luxury tax is separate from GST and does not affect Alberta's no-PST status.
Alberta and GST: Background
Alberta is the only Canadian province with no provincial sales tax of any kind — no PST, no HST, and no QST. Since the federal Goods and Services Tax came into effect on January 1, 1991, the sole consumption tax applied to most purchases in Alberta has been the 5% federal GST, administered by the Canada Revenue Agency. This makes Alberta the lowest sales tax jurisdiction in Canada, a distinction that has become a defining feature of the province's economic identity and competitive positioning relative to other provinces.
Alberta has consistently resisted legislative proposals to introduce a provincial sales tax, and no provincial government has successfully advanced such legislation into law. For businesses operating in Alberta, the absence of a provincial component means there is no split-ITC calculation and no separate provincial tax authority to register with or file returns for. The full 5% GST paid on eligible business inputs is recoverable as an Input Tax Credit through the CRA — a straightforward single-return process that distinguishes Alberta from every other province.
