I am a resident of British Columbia Canada and have been asked by a business in Sweden to do contract work as a web developer. What taxes would I have to pay/charge?
There is no tax. GST does not apply to sales of Intangible Personal Property to customers outside of Canada.
Section 10.1 of Part V of Schedule VI of the Excise Tax Act received Royal Assent on June 22, 2007, and zero-rates all supplies of intangible personal property (IPP) made to non-residents that are not registered for GST. There are, however, certain exceptions, which generally concern supplies of IPP that are closely connected to Canada. The exceptions are akin to other such exceptions found in similar zero-rating provisions for services.
