Can an LLC be a non-profit 501c3? And can a for-profit LLC accept donations via patreon or kickstarter? Can an LLC be a non-profits? Or are LLC's by definition for-profit organizations? If the former, how would that designation be reached?
An LLC can obtain a 501(c)(3) designation, but all its members/owners must also be 501(c)(3) non-profits. So if Red Cross and Habitat for Humanity and Goodwill got together to start an LLC, that LLC could obtain a 501(c)(3) designation. If a human person is a member of an LLC, that LLC cannot obtain a 501(c)(3) designation. I don't think there's any reason a for-profit LLC could not accept donations from Patreon or Kickstarter, but those donations would generally be treated as income, the same as money received in exchange for goods.
What would be an appropriate legal classification? A trust. How could this entity be structured so it could manage multiple estates? As a trust. Could this entity choose to keep, say, 30% for internal use e.g. resuscitation research? If that’s what it says in the trust deed, yes. How could this entity be made "recession-bulletproof," such that it could survive collapse of civilization? It can’t. Could it be given autonomy under the direction of a single person, or even sovereignty along the lines of a Mars colony? A trust is managed by its trustee(s) for the benefit of the beneficiaries. A trustee can be an individual or a corporation and there can be one or more of them. It couldn’t be given sovereignty - only nation states are sovereign. Could it be immune from legal jeopardy if it chose to accept clients who volunteer to be frozen before they die? No. What might happen to the estates if the economy is radically altered, e.g. a scarcity-free system where money is obsolete? Beats me - you’re the science fiction writer, you make it up.
Based on a reply from the Charitable Law Office of Ohio Attorney General: Hello, I am in receipt of your inquiry below. Please be advised that there is nothing to prohibit using electronic storage for your organization’s business documents. Many organizations find this method to be a very effective measure as opposed to retaining hard copies. ... it seems electronic storage is wholly permitted.
You can do it using a US non-profit, but you need a lawyer We know it can be done in the US using a non-profit because it has been done. For example, the Clay Institute’s Millennium Prize does exactly what you propose: it pays people who solve unsolved math problems. Similarly, the the Everglades Foundation used a prize to get people to come up with new ways to get phosphates out of the water sources. To do what they did, you need to follow their lead, and set up and run a non-profit (aka, 501(c)(3), named after the relevant provision of the tax code). Because non-profits are tax exempt under US tax law, you have to apply to the IRS to become a non-profit. Speaking broadly, the IRS imposes two requirements on non-profits: 1) It must serve a charitable purpose; 2) It must spend a certain percentage of its money every year doing charitable work. To set up a foundation you have to specify the charitable purpose you will serve (“encourage research in mathematics”), and have a plan to do so (“we will award a cash prize to people who solve important unsolved problems”). If the IRS decides your plan is genuine, then they give you a pass on paying taxes. To make sure you are carrying out your charitable plan, the IRS requires you to spend a certain percentage of your money each year on charitable work. (This is called the &quot;distribution requirement.&quot;) Meeting the distribution requirement may be a problem, since you may not award prizes every year. You may be able to get a general idea about how the IRS deals with such situations by searching on line. At some point, however, you will probably need to talk to a lawyer with experience setting up non-profits. (FWIW, it looks to me as if the Clay Institute meets its yearly spending requirement by supporting lots of other activities that count towards the spending requirement.) One other problem that it seems you won’t have involves giving prizes directly to individuals. For obvious reasons, the IRS is generally suspicious of prizes given to individuals, so they impose restrictions. For example, for the winner to avoid taxes, the prizes have to be for previous work. Where to go for more information: USA.gov has a nice overview of the application process here. The IRS has several publications and websites that you might find helpful: here, here, here, and here. These cover everything from the general rules to nuts-and-bolts details about which forms to use. You can read more about the IRS treatment of prizes here and here. Depending on how comfortable you are with financial statements, you may learn about how these non-profits work by reading their 990 forms. The Clay Institute's forms are here.
In business dealings, you would have a contract with a company, not with its owner. The new owner inherits both the assets and liabilities of the company. It's up to the buyer of the business to do due diligence before buying the company. The old owner may escape obligations to clients and suppliers once the sale of the business is complete, but the new owner could sue the old owner for fraud. (It may be possible to escape some liabilities by declaring bankruptcy, but that's not the situation you described. One unethical accounting trick that a company can use is to split the company into two corporations such that one branch inherits the liabilities, and it go defunct.)
The company pays you a salary A. They need to withhold some amount B of that to give to the IRS. Now, if they pay you only C and withhold amount D that is based on that amount, and then make a separate tax-deductible donation E, that means the IRS does get not only an amount D that is smaller than B, but also the company can deduct E (in part) from their own taxes. As a result, that sounds like tax evasion on the face. However, if they still pay you A, withhold B (the tax on the whole amount), and payout C to you as well as the donation as part of your salary, that could possibly be a legal way - though you might want to consult your tax consultant.
No An LLC that didn’t exist at the time of the act or omission that caused the loss being sued over is not a valid defendant. They would sue you personally and all of your assets, including the LLC, would be available to the creditor.
united-states The license won't let you sell the .stl file. Probably you have created a derivative work, which means you can't sell it without a copyright license (and the CC-A-NC won't do). If it were licensed under CC-A you could sell it without problems (you'd have to give attribution, of course). You could also sell it under the CC-A-SA, but once you do you have no control over the result -- anyone you sold it to could give it to someone else under the terms of the license. This could work, though, if it were (say) a commission and you only expected to sell one copy. I don't know what the situation would be with the physical objects printed under any of these licenses.
