Classify the supplier’s actual service
Manitoba Bulletin 057 covers taxable accounting services, including bookkeeping. It does not make every form of professional consulting taxable. Where a supplier bundles different services, retain an itemized description and ask for clarification before choosing a tax code. Buying taxable accounting services from an unregistered supplier can require a business purchaser to self-assess RST; an invoice showing no provincial tax is not conclusive evidence of exemption.
Check cloud invoices and the transition
Bulletin 033 brings cloud computing into RST from January 1, 2026, with Manitoba-use rules and possible allocation for users in different locations. Its transition excludes payments made before that date for a service period that began before that date, even if the period continues into 2026. Keep payment and service-period evidence together before deciding that an older prepaid subscription needs an adjustment.
Illustrative example: two monthly supplier charges
Assume a Winnipeg business buys $1,100 of bookkeeping confirmed taxable for Manitoba and a $300 cloud subscription wholly taxable under the current rules. Their RST amounts are $77 and $21, respectively, before considering GST separately. The $98 of provincial tax is recorded with the appropriate purchase treatment rather than entered as a GST input tax credit. If the cloud bill arrives without RST, the owner flags the missing tax for review instead of changing the supplier’s invoice silently.
Use a purchase register to prevent repeated questions
A practical register identifies the vendor, service description, users or relevant location, billing period, payment date and tax shown. Add a link to the invoice and a note of any professional determination. Review it when a subscription changes or users move, rather than assuming last year’s code still answers the question. Keep the original supplier amount visible if a self-assessment entry is needed so the accounting file can explain both entries. The register also gives the owner a useful subscription-cost view: renewals and unused seats can be reviewed independently of the tax decision.
