Manitoba generally charges 5% Goods and Services Tax (GST) and 7% Retail Sales Tax (RST), for a combined rate of 12% on purchases subject to both taxes. RST is Manitoba’s provincial sales tax. Use this Manitoba sales tax calculator to add GST and RST to a price or calculate the taxes included in a tax-inclusive total.
Enter a value in any field—price before tax, GST amount, RST amount or price after tax—and the other values will be calculated automatically. The calculator assumes that both the standard 5% GST and 7% Manitoba RST apply.
Rates last checked: August 15, 2026. The standard rates are 5% GST and 7% Manitoba RST, for a combined rate of 12% when both taxes apply.
Manitoba GST and RST are calculated separately on the selling price before either tax is added. GST is not charged on top of RST, and RST is not charged on top of GST.

How to calculate GST and RST in Manitoba
When a purchase is subject to both standard taxes, calculate 5% GST and 7% Manitoba RST from the selling price before tax.
GST amount = price before tax × 0.05
RST amount = price before tax × 0.07
Price including GST and RST = price before tax × 1.12
For example, if an item costs $100 before tax:
- Price before tax: $100
- GST at 5%: $5
- Manitoba RST at 7%: $7
- Total price after tax: $112
Manitoba RST is calculated on the selling price before GST is added. The combined 12% rate applies only when the purchase is subject to both taxes.
How to calculate reverse GST and RST in Manitoba
To calculate the original price from a total that includes both 5% GST and 7% RST, divide the tax-inclusive total by 1.12.
Price before tax = price including GST and RST ÷ 1.12
For example, if the total is $112, the original price is $100. The total tax is $12, consisting of $5 GST and $7 RST.
Enter the price after tax into the calculator above to calculate the original price and both tax amounts automatically.
Why is Manitoba’s provincial sales tax called RST?
PST is a general term used for a provincial sales tax. Manitoba officially calls its tax Retail Sales Tax, or RST, because it is established and administered under Manitoba’s Retail Sales Tax Act.
The name reflects the tax’s original focus on the retail sale or rental of goods and certain services. Although Manitoba RST performs a similar role to the taxes commonly called PST in British Columbia and Saskatchewan, RST is the official term used by the Manitoba government.
Manitoba RST remains separate from the federal GST. The province has not combined its provincial tax with GST under the Harmonized Sales Tax system. This is why Manitoba receipts commonly show two separate lines:
- 5% federal GST
- 7% Manitoba RST
In HST-participating provinces, the federal and provincial portions are collected as one harmonized tax instead.
RST may sometimes be described informally as Manitoba PST, but “Manitoba RST” is the more accurate term.
