Taxomate integrates with Amazon.ca (Amazon Canada). However, any provincial sales tax collected and remitted is available in your settlement as a lump sum rather than split up by province. If you only collect and remit one type of sales tax (e.g., GST), this may work for you, but you should always speak to your accountant.
We do plan to add the ability to split sales, refunds, etc., by province. To be notified when this is available, please fill out this form.
