We are a Canadian-based incorporated business that is about to sell subscriptions to a SaaS, both yearly and monthly.
How do we handle adding taxes to the service? Since we are a Quebec-based business, do we charge our customer the Quebec tax rate? If our client is based in any particular province/state, do we charge the taxes of that province/state?
Of note, we are not actually shipping any products, only delivering a service online, so I don't know if the location of the client matters or not.
