Is it legal to store gold at home in the USA? Is it legal to store physical gold at home in the US? If so, what taxes may be applied on the gold held at home, in form of both jewelry or raw gold?
Private ownership of gold has been legal in the US since the passage of Pub. L 93-373, which repealed the prohibition of private ownership of gold. You may therefore store it wherever you want. There is no tax on gold, kept as gold, though if you sell it there may be capital gains tax owed on the profits (just as there would be for many other things).
If you cannot legally purchase a gun in Utah due to any restriction, such as residency, and you engage someone else to knowingly buy or gift you a gun (such as a "straw man" purchase from a dealer or private sale), that is illegal. From the same link you posted (my emphasis): Can I buy a firearm as a gift for someone? Yes, as long as the receiver is not a prohibited person and the gifting is not being used to circumvent a background check or other laws. Calling a purchase intended in place of another is a straw purchase.
It might possibly be illegal. For criminal law, usually you need to obey the laws of three countries: The country you are a national of (by personality principle) The country from where you make the sale (by territoriality principle) The country that hosts the attacked interest (by territoriality principle) Then it depends on the jurisdiction (and other factors) whether the sale is legal or not. I'll use the example of my country, Czech Republic. There is a crime called "Unauthorized access to a computer system or data storage device". For example, you commit this crime by exploiting a vulnerability in a web application and copying the web owner's data on your computer. It is also codified that whoever wilfully facilitates the committing of a crime by providing the criminal with resources (such as the exploit) is considered to have also committed the crime. For this to apply, you must have known or expected that the exploit will be used to commit a crime. The courts would decide this.
First, there's no tax credit (at least on the Federal side), just a tax deduction (and even that isn't guaranteed - depends on your personal circumstances). Second, you get to claim the deduction (you should keep your receipt, just in case).
As indicated here, throwing away mail is the crime of obstructing mail. There is no exception for "junk mail" i.e. standard mail. It is possible (virtually guaranteed) that an individual postmaster or the USPS has a different disposition of the two kinds or mail when returned, but that is about USPS and not you. It is highly unlikely that you will find an official statement to the effect that it is "okay" to violate the law in the case of disposition of returned standard mail, even if in fact there is virtually no chance of being prosecuted for recycling. I assume that the junk mail is not addressed to "or current resident", or simply "Resident", because then the letter is addressed to you and you can do what you want.
If the owner of the intellectual property leaves property subject to the jurisdiction of the state of Washington, and it is determined that the owner is dead and has no heirs, then per RCW 11.08.140 it is designated escheat property. Then the following sections specify that title to the property vests in the state. The Department of Revenue has jurisdiction over that property, which has the duty to protect and conserve the property for the benefit of the permanent common school fund. There is no general answer to the question of what would best benefit the school fund. Any form of giving it away would not benefit the school fund, at least if there was an viable option for sale / licensing. There are provisions that relate to the possibility that an heir is eventually uncovered, but I will assume that no heir ever appears. Ohio law is similar. The decendant's property escheats to the state in case there is no heir. Then under ORC 2105.07, the prosecuting attorney of the county in which letters of administration are granted upon such estate shall collect and pay it over to the county treasurer. Such estate shall be applied exclusively to the support of the common schools of the county in which collected.
On the first page of https://www.gov.uk/duty-free-goods/overview you find: "You can bring some goods from abroad without having to pay UK tax or ‘duty’ (customs charges), as long as they’re for your own use." And on the next page "... will use them yourself or give them away as a gift". This clearly doesn't cover anything that you bring into the UK to sell it. And a bit further on the site it says "You must tell customs (known as ‘declaring’) on arrival in the UK if you have goods: ... that you plan to sell". Since you are asking here, it is quite obvious that you intend to sell :-) You said "e.g. say this guys comes every month from Russia to France for unrelated business, each time he fills up his luggage with the maximum allowed amount of goods that comply with custom laws". If this guy sells the stuff to you, then the maximum allowed amount of goods to import without paying taxes is zero. Once he is willing to pay taxes, there is no limit. Obviously regularly importing things from Russia or France and selling in the UK at a profit means that he is running a business in the UK, which means he would have to register a business, pay corporation taxes etc. It's all a matter of degree; for small amounts nobody cares (up to some limit you don't need to register a business or pay taxes; I don't know the details).
Here is the state of California code regarding the question. I am sure a state by state inquiry could reveal other statutes. http://www.leginfo.ca.gov/cgi-bin/displaycode?section=pen&amp;group=00001-01000&amp;file=565-566 In California there is no specific registry but registration is performed by marking the container with a registered brand.
