Are you a business in Scottsdale selling to Canadians while assuming your GST/HST filings are as they should be? This assumption is already a problem. A single misfiled GST/HST return, and you could incur CRA penalties, interest, or a review of your compliance, even if you are a U.S. business without an actual presence in Canada.
As cross-border eCommerce, SaaS, and digital services from Arizona continue expanding, Canadian tax authorities are more scrutinizing non-resident suppliers. Scottsdale merchants think their U.S. CPA ‘handles everything’ and find out later GST/HST compliance is a technical matter all by itself.
