About Manitoba Sales Tax
Manitoba levies a combined sales tax rate of 12%, which includes the federal GST of 5% and a provincial tax known as Retail Sales Tax (RST) at 7%.
The Retail Sales Tax is administered by Manitoba Finance. Both taxes are calculated on the pre-tax price. The rate is uniform across Winnipeg, Brandon, and all other municipalities.
Tax Rates in Major Manitoba Cities
* Unlike in the US, Canadian provinces apply sales tax uniformly across all municipalities. City-level or county-level surcharges do not exist in Canada.
Input Tax Credit (ITC) Reconciliation for Manitoba Businesses
Eligible Tax & CRA Filing Target
Eligible Tax: 5% Federal GST component only (7% provincial PST is expensed)
Filing Return: CRA Form GST34 (Line 106 / Line 108 Input Tax Credits)
Recovery Rate: 5% Federal GST is 100% ITC recoverable; provincial PST is expensed on corporate tax filings
CRA Documentary Rules & Recovery Guidelines
- In Manitoba, only the 5% federal GST portion qualifies for CRA Input Tax Credits. The 7% provincial PST does not qualify for an ITC because PST is a single-incident consumer tax.
- Accounting Treatment: The 7% PST paid on business inputs must be capitalized or expensed as an operating cost on your financial statements (T2 or T2125), rather than claimed as an input tax credit.
- Statutory Reverse Formula: Pre-Tax Base = Total Paid ÷ 1.12. Claimable Federal GST ITC = Pre-Tax Base × 0.05. PST Expense = Pre-Tax Base × 0.07.
- Documentary Requirements: Vendor receipts must display their 9-digit GST registration number and show either the GST amount separately or state that GST is included.
Worked Example for Manitoba Receipt
