Ask HN: Does a Canadian online retailer have to pay US taxes on US sales?
https://news.ycombinator.com/item?id=15095370I just started working with a small Canadian online retailer that has always done the majority of their business in Canada.
US sales have been considered sales and included in income on the Canadian taxes and a US tax return has never been filed.
As we grow the business in the States, do we have US tax liability even if we don't have a physical presence? Do we have to collect US sales tax? Pay US income taxes? Does this change if we open a warehouse in the states? I would hate to invest my effort in this and find out that we owe a bunch of back taxes. Any information is greatly appreciated.
