The Simplified Registration Vendor Trap

Since July 2021, foreign digital vendors like AWS, Salesforce, and Adobe can register under Canada’s simplified GST/HST framework. Tax charged under this regime is non-recoverable as an Input Tax Credit. Most Canadian businesses don’t know — and CRA denies the claim on audit.

The Problem

Under the ETA Digital Economy Measures (July 1, 2021), non-resident digital service providers can register under a simplified GST/HST framework instead of the standard regime. This means:

  • They charge GST/HST on invoices to Canadian customers
  • But the tax they collect is not eligible for ITC recovery by the purchaser
  • Canadian businesses that claim ITCs on these charges face denial and reassessment on CRA audit

The fix is straightforward: provide your GST/HST registration number to the vendor. Once they have it, they stop charging you tax under the simplified regime. But most businesses never realize this is happening.
