What are the tax implications for a business incorporated outside the US, but with a good percentage of users and 5% of its workforce there?

There shouldn't be any tax consequences for the founders if you've made 83b elections--the election meant you paid tax already on the full value of the stock at the time of the election (presumably zero) even though it was subject to future forfeiture. If you sell newly-issued stock there should be no tax impact. If you sell your own common stock, you'd pay tax on the gain, but I doubt that is what you mean here. Of course, you should not take the free advice dispensed on Clarity and consult your own tax preparer--this is not tax advice.

The income should be reported by the individual or business that provided the service and earned the income. If the 1099 is in your name, you could ask the issuing Company to change to the S-Corp if that is who earned the income. In the future, have a written agreement between your S-Corp and the Company you are providing service. Also, provide them with a Form W9, so they know where to report the 1099 income at year end.

Delaware C-Corp I usually Delaware is the best choice for any startup looking for fundraising with a US focus. However, if you are a remote and global team, an overseas or foreign corporation or US tax purposes might make sense. You'd have to talk to an advisor who can dive into your situation, but it would be more difficult for the US owner come tax time, as he'd likely have to file form 5471 to the IRS for any controlled foreign corporation, and form 90-22.1 for any foreign bank accounts. There are a lot of other concerns I didn't hear you raise that entrepreneurs usually have and ask me about, namely banking and merchant accounts/ payment processors. In terms of accepting online payments, any US corporation or LLC is far and away the best option for a company. It's difficult to suggest without knowing more about the company but you might explore Delaware, Wyoming, Hong Kong and other offshore jurisdictions for your legal entity. Each tend to have positives and negatives and there is no one size fits all solution. I do write about issues of incorporation quite regularly on my website FlagTheory.com - so you can read those articles for free, or we can schedule a call - Clarity.fm/incorporation when you have specific questions. Thank you and hope this was helpful!

If you have an existing space, why not consider leveraging the current tenants for part of the money needed? Spend some money (tenants can pitch in for that instead) in a fundraising party! Invite local band, caterer (ask for discount in exchange of promotion) have some context for the event such as idea pitching, or brownbag, etc... as the main entertainment... sell tickets for that event. Might not give you all you need but will help get there. _ aim for double what you spend at a minimum! Try gofundme.com Get in the news and ask for community support. Get infront of the local development offices ans ask for grants (this is common) as it helps development. These are just some ideas. best of luck

yes. As long as your main place of work is your home/office.
