How should the payment for the PO Box fee be divided up or deducted when sharing with 3 companies?

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!

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.

I would suggest the first question to ask is "what problem do I solve?" And of those people I solve problems for "who do I create the most value for?" In the non-profit world you need to add "How does my business help the non-profit run better and/or help the group the non-profit focuses on?" For example, if you've created a platform that drives donations, your company "has created a platform that helps you reach fundraising goals faster." What you don't want to do is market and sell to B2B and B2C audiences simultaneously. They have different ways of buying - a B2B audience needs to have their benefits quantified (using your thing makes me x amount more) - and it's extremely hard for a startup to be able to do both well. Better to start with one, execute really well and move into the other. Feel free to give me a call and we can dig into who your most valuable audience is.

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

Non-profit is incorporated as a 501c(3) and must be approved by the government for the tax advantages to take effect. A social business or perhaps a Benefit Corporation is a new corporate structure available in certain states that allow the for profit corporation to put the "Social Mission" of the company ahead of the "Shareholder Profits".
