Hello! You have an excellent site with a lot of information that’s been really helpful for my small business. I am a Canadian running a sole proprietor, service-based business. I’m considering taking on a contract from a US company that could be worth more than $100,000 USD. Most of that would have to be paid out to subcontractors in Canada, USA and Australia that I will have to hire to do the work. Will I need to pay the IRS? What’s the best way to handle the Canadian taxes? Should I continue as a sole proprietorship? Are there any other tax implications that I should consider? Thank you!
