Does earning as a non-resident remote worker on an American account make people liable for U.S taxes?
The United States taxes nonresident aliens on two types of income: First, a nonresident alien who is engaged in a trade or business in the United States is taxed on income that is effectively connected with that trade or business. Second, certain types of U.S.-source payments are subject to income tax withholding. The determination of when a nonresident alien is engaged in a U.S. trade or business is highly fact-specific and complex. However, keeping assets in a U.S. bank account should not be treated as a U.S. trade or business. A nonresident alien's interest income is generally subject to U.S. federal income tax withholding at a rate of 30 percent under Section 1441 of the tax code. Interest on bank deposits, however, benefit from an exception under Section 1441(c)(10), so long as that interest is not effectively connected with a U.S. trade or business. Even though no tax needs to be withheld on interest on a bank deposit, the bank should still report that interest each year to the IRS on Form 1042-S. The IRS can then send that information to the tax authority in Brazil. Please keep in mind that state and local tax rules are all different, and whether interest on the bank deposits is subject to state or local tax will depend on which state the bank is in. Also, the United States does tax nonresident aliens on wages paid from a U.S. company, if those wages are treated as U.S.-source income. Generally, wages are U.S.-source income if the employee provides services while physically present in the United States. There are a few exceptions to this rule, but they depend on the amount of wages and other factors that are specific to the employee's situation.  This is an area where you should really consult with a U.S. tax advisor before the employment starts. Maybe your company will pay for it?
Many European countires allow you to an account for non-residents. You have to appear in the bank personally to open it, some of them even to get your own tax number for non-residents from the local government.  I'm not sure if you get a Visa (Electron) chip card immediatelly or you have to wait for like 3 months before being issued one. I've heard that getting a tax number for non-residents and opening a bank account is easily done in one day in Brezice, Republic of Slovenia. They seem to have agile local bureaucracy and banks, since many pople from neighbouring (non-EU) countries (used to) come there to open an EU bank account. Funds can be transfered via Internet banking - US banks have that, do they? SWIFT and IBAN codes are used for international money transfer. But it takes some time (days!) for it to arrive to destination. Tansfers below $20000 per month or per transaction are considered normal, but for amouts above that the destination bank might ask you to explain the purpose, to prove it is not illegal. Some of them accept the explanaiton in writing (they forward it to the regulator that tracks such large transfers), some of them ask you to appear there in person for an interview and to sign a statement. Can't believe US banks are still issuing paing magnet stripe cards like it's still 1980s. I'd expect Europe to be 10 years behind USA in technology, but this seems to be a weird reverse. I've beed using Internet banking with one-time passwd tokens and TAN lists for almost 10 years, and chip cards exclusivley for over 5y. Can't remeber the last time I've seen mag stripe card only. American Express (event the regular green one) got the chip at least 5 years ago. And it is accepted regularly in Europe. Alegedly it's more popular in Europe (although Mastercard is a definite #1, with Visa close to that) that in USA. The finance team from your company should be able to advise you. From what I understand you are Indian Citizen for Tax purposes. Any income you receive globally is taxable in India. In this specific case you are still having a Employee relationship with your employer and as such the place of work does not matter. You are still liable to pay tax in India on the salary. If you are out of India for more than 182 days, you can be considered as Non-Resident from tax point of view. However this clause would not be of any benefit to you as are having a Employee / Employer relationship and being paid in India. Edit: This is only about the India portion of taxes. There maybe a UK protion of it as well, plus legally can you work and your type of Visa in UK may have a bearing on the answer "The IRS W-8BEN form (PDF link), titled ""Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding"", certifies that you are not an American for tax purposes, so they won't withhold tax on your U.S. income. You're also to use W-8BEN to identify your country of residence and corresponding tax identification number for tax treaty purposes.  For instance, if you live in the U.K., which has a tax treaty with the U.S., your W-8BEN would indicate to the U.S. that you are not an American, and that your U.S. income is to be taxed by the U.K. instead of tax withheld in the U.S. I've filled in that form a couple of times when opening stock trading accounts here in Canada.  It was requested by the broker because in all likelihood I'd end up purchasing U.S.-listed stocks that would pay dividends.  The W-8BEN is needed in order to reduce the U.S. withholding taxes on those dividends. So I would say that the ad revenue provider is requesting you file one so they don't need to withhold full U.S. taxes on your ad revenue. Detailed instructions on the W-8BEN form are also available from the IRS: Instruction W-8BEN (PDF link). On the subject of ad revenue, Google also has some information about W8-BEN: Why can't I submit a W8-BEN form as an individual?" As the name says, its for income earned in a Foreign country. If you have been paying US income tax on this while living in the US, nothing is going to change here. You should be informing yourself on how to avoid double taxation in your new country of residence. Passive income earned abroad (dividends, interest) also do not fall under this exemption.  The purpose of the Foreign Earned Income Exclusion is to make it easy for expats who work abroad to avoid double income taxation without going through the complicated process of applying for tax credits. The US is the only industrial country that taxes its residents regardless of where they reside. That is also why it only goes to about $100,000 a year. If you are a high earner, they want to make it more difficult. Also as a side note, since you are going to be abroad for a year. I will point out that if you have more than $10,000 in foreign accounts at any point in the year you need to declare this in an FBAR form. This is not advertised as well as it should be and carries ridiculous penalties for non-compliance. I can't count the number of times I have heard a US expat say that they were unaware of this. "There is no penalty for foreigners but rather a 30% mandatory income tax withholding from distributions from 401(k) plans. You will ""get it back"" when you file the income tax return for the year and calculate your actual tax liability (including any penalties for a  premature distribution from the 401(k) plan). You are, of course, a US citizen and not a foreigner, and thus are what the IRS calls a US person (which includes not just US citizens but permanent immigrants to the US as well as some temporary visa holders), but it is entirely possible that your 401(k) plan does not know this explicitly. This IRS web page tells 401(k) plan administrators Who can I presume is a US person?   A retirement plan distribution is presumed to be made to a U.S. person only if the withholding agent: A payment that does not meet these rules is presumed to be made to a foreign person.  Your SSN is presumably on file with the 401(k) plan administrator, but perhaps you are retired into a country that does not have an income tax treaty with the US and that's the mailing address that is on file with your 401(k) plan administrator? If so, the 401(k) administrator is merely following the rules and not presuming that you are a US person. So, how can you get around this non-presumption? The IRS document cited above (and the links therein) say that if the 401(k) plan has on file a W-9 form that you submitted to them, and the W-9 form includes your SSN, then the 401(k) plan has valid documentation to associate the distribution as being made to a US person, that is, the 401(k) plan does not need to make any presumptions; that you are a US person has been proved beyond reasonable doubt. So, to answer your question ""Will I be penalized when I later start a regular monthly withdrawal from my 401(k)?"" Yes, you will likely have mandatory 30% income tax withholding on your regular 401(k) distributions unless you have established that you are   a US person to your 401(k) plan by submitting a W-9 form to them." There's no law that prohibits a US citizen or US LPR from holding an account abroad, at least in a country that's not subject to some sort of embargo, so I don't see how it could affect your wife's chances of getting US citizenship when she's eligible. As mentioned by other posters, you'll have to file FBAR if the money you have in all your accounts abroad exceeds $10k at any point of the year and if the account pays any interest, you'll have to tell the IRS about the interest paid and (if applicable) taxes you paid on the interest income abroad. Completely different. Canadians can be deemed non-residents by severing their residential ties with Canada and emigrating to another country, and no longer required to file unless they have certain sources of Canadian income. *See* http://travel.gc.ca/travelling/living-abroad/taxation   No such classifications exist with US citizenship. You file a return no matter what, even if you haven't stepped foot in the US in decades. Answering for US tax only: The bank account makes absolutely zero difference.  If you are not a US national and not resident in the US, but earn income from a US employer/client/customer, generally that income is not subject to US tax (no matter where it is banked). However there are (complicated) exceptions, particularly if you are considered to be operating a 'trade or business' in the US or US real estate is involved. Start at https://www.irs.gov/individuals/international-taxpayers/nonresident-aliens and proceed through pub 519 if you have time to spend. I do not know (or answer) about Argentinian taxes. Whether you can find a US bank that wants to open and maintain an account for a foreigner (which is extra paperwork and regulation for them) is a different Q, that is already asked and answered: B1/B2 visas do not allow you to work, but that isn't really in scope of money.SX and belongs over on travel.SX (or expatriates.SX for longer stay);  https://travel.stackexchange.com/questions/25416/work-as-freelancer-while-tourist-in-us-for-an-already-existing-us-client seems to cover it.
