Sales Tax Licence/Permit - When is it required and how can I make a use of it as a non-US resident selling in USA?
Sales tax permits come from the state in which your business is operating.  You need a business license first for them to issue you one. US sales taxes are collected by the business and remitted to the government, you need the permit in order to do this. A bigger question is whether it's legal for you to engage in business in the first place.  What is your visa status? Disclaimer: I am not a tax specialist You probably need a sales tax permit if you're going to sell goods, since just about every state taxes goods, though some states have exemptions for various types of goods.  For services, it gets tricker. There is a database here that lists what services are taxed in what states; in Wyoming, for example, cellphone services and diaper services are taxed, while insurance services and barber services are not.  For selling over the internet, it gets even dicier. There's a guide on nolo.com that claims to be comprehensive; it states that the default rule of thumb is that if you have a physical presence in a state, such as a warehouse or a retail shop or an office, you must collect tax on sales in that state. Given your situation, you probably only need to collect sales tax on customers in Wyoming. Probably.  In any event, I'd advice having a chat with an accountant in Wyoming who can help walk you through what permits may or may not be needed.
Getting the first year right for any rental property is key. It is even more complex when you rent a room, or rent via a service like AirBnB. Get professional tax advice. For you the IRS rules are covered in Tax Topic 415 Renting Residential and Vacation Property and IRS pub 527 Residential Rental Property There is a special rule if you use a dwelling unit as a personal   residence and rent it for fewer than 15 days. In this case, do not   report any of the rental income and do not deduct any expenses as   rental expenses. If you reach that reporting threshold the IRS will now expect you to to have to report the income, and address the items such as depreciation. When you go to sell the house you will again have to address depreciation. All of this adds complexity to your tax situation. The best advice is to make sure that in a tax year you don't cross that threshold. When you have a house that is part personal residence, and part rental property some parts of the tax code become complex. You will have to divide all the expenses (mortgage, property tax, insurance) and split it between the two uses. You will also have to take that rental portion of the property and depreciation it. You will need to determine the value of the property before the split and then determine the value of the rental portion at the time of the split. From then on, you will follow the IRS regulations for depreciation of the rental portion until you either convert it back to non-rental or sell the property.  When the property is sold the portion of the sales price will be associated with the rental property, and you will need to determine if the rental property is sold for a profit or a loss. You will also have to recapture the depreciation. It is possible that one portion of the property could show a loss, and the other part of the property a gain depending on house prices over the decades. You can expect that AirBnB will collect tax info and send it to the IRS As a US company, we’re required by US law to collect taxpayer   information from hosts who appear to have US-sourced income. Virginia will piggyback onto the IRS rules. Local law must be researched because they may limit what type of rentals are allowed. Local law could be state, or county/city/town. Even zoning regulations could apply. Also check any documents from your Home Owners Association, they may address running a business or renting a property.  You may need to adjust your insurance policy regarding having tenants. You may also want to look at insurance to protect you if a renter is injured. "Context: My parents overseas (Japan) sent me a little over $100,000 to   cover an expensive tuition payment and moderate living expenses in   2014. They are not US residents, Green card holders or citizens. They did not remit the tuition payment directly to the school. I am a   resident (for tax). This is enough to answer yes. That's basically the set of requirements for filing: you received >$100K from a non-US person and you yourself are a US person. You have to report it, and unless it is taxable income - it is a gift. Taxable income is reported on the form 1040, gifts are reported on the form 3520. The fact that in Japan it is not considered a gift is irrelevant. Gift tax laws vary between countries, some (many) don't have gift taxes at all. But the reporting requirement is based on the US law and the US definition of ""gift"". As I said above, if it is not a gift per the US law, then it is taxable income (and then you report all of it regardless of the amount and pay taxes). Had they paid directly to the institution, you wouldn't need to count it as income/gift to you because you didn't actually receive the money (so no income) and it went directly to cover your qualified education expenses (so no gift), but this is not the case in your situation. Whether or not this will be reported by the IRS back to Japan - I don't know, but it was probably already reported to the authorities in Japan by the banks through which the transfers went through. As to whether it will trigger an audit - doesn't really matter. It was, most likely, reported to the IRS already by the receiving banks in the US, so not reporting it on your tax return (either as income or on form 3520) may indeed raise some flags." it just depends on your situation and sometimes accounting can't fix that.  by mentor pays 35% even though he only goes back to the USA to visit. I go back less than 30 days a year so I can claim I'm a foreign resident but if all my income is in the USA I'm screwed.   I can't even route my income through my wife who has never stepped foot in the USA because we must claim whatever she makes.    US tax laws are so bad that it takes a lot just to get an account with HSBC in Hong Kong 1) Document that you held the bitcoins for more than one year. This should not be particularly difficult. Since you haven't moved the bitcoins, you hold the key to an address that has held them for more than one year. While this isn't absolute proof, it should be sufficient. 2) Since you can't document how you bought them easily, you can just assume a tax basis of zero. This will mean you will pay microscopically more in taxes, but don't worry about it. 3) Sign up with an exchange that can handle your sales. Coinbase will work if you want to sell it slowly. Gemini will work if you want to sell more quickly. 4) Get a decent, secure bitcoin wallet. Transfer the bitcoins to the exchange only as you're selling them. Make you first sale fairly small just in case something goes wrong. 5) Keep meticulous notes about each sale -- the date of the sale, the number of bitcoins you sold, and the number of dollars you got. 6) Make sure to keep enough money for taxes. In Michigan, 24.3% would be the highest possible tax rate you might have to pay if you sold a lot or had high income otherwise. 7) Either get a professional to file your taxes for you or learn how to correctly report long-term capital gains. You must report each individual sale. You may get audited or investigated, but there's nothing to find. The bitcoins have been in stasis for a long time, and it's completely plausible that you bought them and held them. If you can find any proof you bought them (such as a transfer to an exchange) that would be great, but it's not essential. Many people have this same story and unless you're connected to something illegal, you probably don't have anything to worry about. Congratulations! So thats my question, what steps do I need to take to declare this money and obtain it without getting arrested / investigated? There's nothing special you need to do other than keep very good documentation. When you file your taxes, you will need to declare each sale. (This answer assumes that you didn't have a lot of income last year and significantly less income this year. If that's the case, you may have to pay estimated taxes to avoid a penalty. But that penalty is very small and will be calculated by the IRS for you automatically. So I wouldn't worry about it.) You may wish to read up on gift taxes to understand how they work. You won't owe any, but you may need to file paperwork with the IRS if you give large gifts (over $14,000) to people and you will use up some of your lifetime exemption. Keep records of any gifts you give. Yes you do. You're under the jurisdiction of at least one country where you're resident, or where you're citizen. You may be under jurisdiction of more than one country. Each country has its own laws about what and how should be taxed and countries have treaties between them to resolve jurisdiction issues and double taxation situations, so you should talk to a tax accountant licensed to provide you with an advice. "Re the business license - in California business licenses are given by the municipal/county governments, so you'll have to check that with your city hall or county office. Re taxes - yes, you'll have to pay taxes, as with any income. Services are considered ""imputed income"", and generally you'd recognize income to the extent they would be paying had they been paying the full price (or the actual cost of services provided, if more). Since this is a hobby and not a for-profit enterprise, your deductions may be limited by the actual income and the 2% AGI threshold. See more here." The money you will be bringing to the US will be classified as your own money, and will not be taxable. The proceeds from the sale are taxable to you, probably as capital gains. The fact that you kept the proceeds out of the US is irrelevant for that purpose (it is relevant for FBAR/FATCA etc). Since you had no basis in the property, all the proceeds are taxable to you at the time of the sale and should be reported on your tax return. Unless you started a bank or other kind of a financial institution (brokerage, merchant processor, etc etc), the page you linked to is irrelevant. That said, there's enough in the US tax code for you to reconsider your decision of not living in the US, or at least of being a shareholder of a foreign company. Your compliance costs are going to go through the roof. If you haven't broken any US tax laws yet (which is very unlikely), you may renounce your citizenship and save yourself a lot of money and trouble. But in the more likely case of you already being a criminal with regards the US tax law, you should probably get a proper tax advice from a US-licensed CPA/EA who's also proficient in the Japanese-American tax treaty and expats' compliance issues resolution.
