Manitoba Retail Sales Tax adds to federal GST on many goods. A C$112 tax-included total often reflects C$100 pretax, C$7 RST, and C$5 GST.
Register with Manitoba Finance for RST when thresholds apply, and with CRA for GST.
Brandon and Thompson retailers must show RST and GST separately on registered invoices so buyers can match each levy to provincial and federal filing schedules.
Farm equipment and inputs may have exemption rules—reverse only where tax appears. Cross-border sales from Manitoba warehouses must use buyer destination rates.
Winnipeg Shopify merchants reconciling gross payouts need per-order 12% splits—not Alberta 1.05 or Ontario 1.13—when the delivery address is in Manitoba.
Certain farm inputs, manufacturing equipment, and prescribed services may be RST-exempt while GST still applies at 5%. Split mixed carts before dividing one blended rate across the entire tax-included total.
Monthly RST filers compare POS jurisdiction reports to Manitoba Finance returns. Reverse calculation on a sample of tax-included receipts catches rate table errors before reassessment notices arrive.
Standard goods: total ÷ 1.12 ≈ pretax. Confirm RST-exempt categories separately.
Interprovincial sales from Winnipeg to Saskatchewan use SK rates at destination—never assume Manitoba 1.12 on cross-border ecommerce orders.
