Can you go to jail for not paying taxes? In what circumstances can you go to jail for not paying taxes in the US/UK? For instance the company doesn't pay taxes for very long time and government can't take any money from the company. Is it different whether it's sole-trader or sole-member LTD/LLC company?
A special case is not paying the income tax that the company is supposed to be paying on behalf of its employees. If an employee makes £4,000 a month, and the employer is supposed to pay £1,000 tax and doesn't, that's not the employer's money, that's the employee's money. Not paying the employee's money is a much more serious matter than not paying your own taxes. A google search found this article http://www.gaebler.com/Not-Paying-Payroll-Taxes.htm which says that a person not paying taxes for employees is personally liable, that this liability does not go away with bankruptcy, and that jail is possible. So their advice is: Whatever other debt you have, paying taxes for your employees' payroll is the absolutely highest priority (higher priority than paying wages, paying the rent, paying company taxes and so on).
A person's property cannot be seized in the US except by due process of law. There is no law that declares the property of a convicted person to be forfeit to the state. A person who is convicted might be subject to a fine, in which case a court could order seizure of property to pay the fine. Your property might also be seized as a result of a civil forfeiture proceeding (where the government sues your property for being the fruit of an illegal enterprise), but that only applies to property believed to be connected to a crime (e.g. purchased with the proceeds of a crime). Civil forfeiture doesn't even require that you be arrested. Barring that circumstance, the person retains their rights to their property. It is then up to them to make suitable arrangements for the protection or disposition of their property.
In the U.S.: To my knowledge all states and jurisdictions that with a "sales tax" technically have a "use" tax, which means the tax liability falls on the purchaser. However, they require "businesses" (whose exact definition varies by jurisdiction) to collect and remit that tax on behalf of "consumers" (which can also vary, e.g., to exclude businesses that resell). Historically consumers have avoided paying use taxes by purchasing from out-of-state businesses that are not subject to their home states' laws on withholding the use tax: while technically a violation of the tax law neither consumers nor states have had an interest in calculating or auditing use taxes owed, except in the case of very large and unusual transactions. There is a large effort underway by states and "brick-and-mortar" stores that lose business to this virtual "mail order tax exemption" to subject out-of-state businesses to the requirement of collecting use taxes on behalf of the state. A few online businesses (notably Amazon) have acquiesced to this demand. To answer your question: In the U.S., an individual who is not making a "business" of selling items or services is generally exempt from the requirement to collect sales tax. It is the purchaser who has the legal obligation to declare and pay tax on such transactions. But purchasers rarely do.
As in most of the world, there is a BIG difference between a person running a business and a person owning a company which runs a business. In the first case, the person is liable for all the debts of the business, in the second case, providing they have fulfilled the legal duties as am owner/director (as applicable) they are not liable for the debts of the company. One of those legal duties is to stop racking up debts you can't pay. In either case, your friend needs professional advice (legal and/or accounting) NOW! A person who is insolvent (cannot pay their debts as and when they fall due) can seek protection from their creditors through bankruptcy. German bankruptcy law, by most standards, is brutal but not so brutal as to take away parenting rights or put the person in jail.
You are a resident of one state, and a non-resident of the other. Or you could be a "part-year resident" of both. Read the applicable personal tax rules for each state, or hire an accountant to do it for you. Note that, in the end, each dollar of income is only taxed by one state. It's figuring out which state that gets tedious.
A receipt is just a written proof that money was taken. It is hard to imagine a place on Earth where the legality of giving such a proof would be questionable at all so that you would need to talk about an "authority to issue receipts". Only if you find a place where money itself is illegal. Now, the real question here is whether such receipts (issued by private persons not registered as businesses) can be used for accounting purposes, e.g. to claim that your business, which transacted with those persons, incurred expenses. The mere fact that sole traders need to be registered to do business does not outlaw the use of receipts issued by non-registered persons. For example, your business could be buying old stuff from the public (used cars, electronics etc.) and refurbishing it. Provided that this activity itself is not illegal, receiving receipts from those one-off private sellers, and using them in your bookkeeping would be perfectly legal too.
Usually, the only reason to set up an &quot;ownerless&quot; corporation is to set up a non-profit. Non-profit corporations can have self-perpetuating boards and are very similar to charitable trusts. If it ends up without any board members and has a self-perpetuating board, any person affected by the corporation or a suitable government representative (in the U.S., usually a state attorney general in the place of incorporation) can apply to a court to have new board members appointed. In a &quot;for profit&quot; context, this generally doesn't happen because the people investing in the company want to be able to profit from it and/or obtain a return of their investment. So, the question is largely hypothetical in that case.
Given that this is a UK based company, the most applicable Act would be the Unsolicited Goods and Services Act 1971 A person who, not having reasonable cause to believe there is a right to payment, in the course of any trade or business makes a demand for payment, or asserts a present or prospective right to payment, for what he knows are unsolicited goods sent (after the commencement of this Act) to another person with a view to his acquiring them [for the purposes of his trade or business], shall be guilty of an offence and on summary conviction shall be liable to a fine not exceeding level 4 on the standard scale. This law specifically refers to [unsolicited] charges for entries in directories. You also mentioned that they're misrepresenting that a company is already a customer and sending out invoices on that basis. That would be a breach of the Fraud Act 2006 A person is in breach of this section if he dishonestly makes a false representation As to their enforceability, that answer is no. If this came before an actual judge, the judge would throw it out in a heartbeat. No agreement was made to provide a service in return for a payment and these companies rely on sending threatening letters via (seeming) third-parties precisely because they wish to avoid that level of scrutiny.
