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.
The Financial Impact
Known Simplified-Registration Vendors
These vendors are registered under the simplified framework. If your AP ledger contains invoices from any of them with GST/HST charges, your ITCs may be at risk.
How Input Recovery Detects This
Type 25 detector scans every vendor against the known simplified-registration list
Flags digital service keywords (SaaS, subscription, cloud, API, streaming) for fuzzy matching
Calculates total exposure: tax amount x number of affected invoices
Recommends action: provide your GST/HST number to each vendor to stop future charges
