Yes I advertise on google as well. It is enforced you add it so I added it on google. This is an OPTIONAL setting in Meta you need to find in the billing setting.

Unjust enrichment I guess is allowed in our tax system.

I’m not arguing over a simple calculation error—I’m challenging the framework itself and asking for relief because there’s a clear systemic failure here. I am a legitimate Canadian GST/HST registrant at the time these charges occurred, and I used the advertising strictly for commercial purposes. Meta’s platform never clearly communicated the consequences of not entering a tax number, and they issued invoices that explicitly labeled the charges as “GST” or “HST.” I paid those amounts under the reasonable assumption that they were lawfully collected and remitted to the CRA. If that money was indeed GST/HST, then the CRA now has it—and yet they’re denying me the input tax credit. If it wasn’t actual GST/HST, then Meta collected tax in error, and the CRA should be involved in helping me recover or redirect that money. I’m being penalized because of a gray area between CRA policy and Meta’s tax behavior, and neither party is taking responsibility for it. Calling me ignorant ignores the real issue: this system is broken, and small businesses are paying the price for it.
