About

Checks quarterly taxable supplies against the GST/HST small-supplier threshold ($30,000 in a single calendar quarter or over four consecutive quarters), shows what the CRA text says about when registration takes effect, which reporting period applies by annual taxable supplies ($1.5 million and $6 million breakpoints), whether the quick method limit ($400,000) is met, the electronic filing and $10,000 electronic payment rules, the same test with Revenu Quebec wording for GST and QST, and a weekly threshold-watch summary with headroom and a run-rate projection. Every threshold names its source, page date and verification level. Simplified: associated-person, exempt-supply and public-service-body detail are not modelled.

Sources: Reference data from official sources (canada.ca, revenuquebec.ca); every answer states its source, date and validity period.
