I run a mobile gaming company with my brother located in California, we just contracted a couple independent contractors(ICs) from the UK to do some art for our games.
Usually, when we contract an IC we ask them to provide their #SS so we can file taxes according. Since people in the UK don't have #SS what do they provide us with? Do they have to apply for a Tax-Id/EIN number?
FYI: I'm currently doing all the book-keeping myself, it isn't much work since we don't have a lot of money coming in at the moment and we don't have employees. My brother and I are the sole owners of the company, we're established as a partnership. So I figured I would do it in order to save us some money until we have money coming in.
First: I'm not an accountant, or a tax adviser, or anything of that sort.
I've looked into this sort of thing for an affiliate program I'm building. I believe we're in the same boat because in the eyes of the IRS affiliates are independent contractors.
It's my understanding that if your contractors in the UK have no US activities, you simply need to collect a statement from them to that effect. If they have US activities, I think you'd ask them to fill out a W-8.
