Hi have my business (incorporation) based in Canada but want to expand to USA. Anyone who has experience and can provide guidance or tips on tax. It is easy switch on shipping to USA in Shopify but want to know tax obligations. Thanks.
I second @BobsMojo's suggestion to consult a professional. Since you're in Canada, you have access to the Canada Revenue Agency's Liaison Officer service. It's a free service, and you'll be speaking to some of the most knowledgeable people in Canadian taxes. If you get a chatty guy like I did, you can get some very fun stories, too!
When we first started Intuitive Shipping Inc., I had a 2-hour meeting with a fantastic gentleman from the service. He answered all of my questions and really set us up in the right direction to ensure compliance. Our accountant echoed the exact same advice the liaison did and also noted we saved money from not having to spend so much time asking him questions or fixing our mistakes.
I hope this helps with your expansion into the States!
