How to know more about my tax situation in the States
The LLC (not you) is probably in debt to the California FTB. Any LLC registered in California must pay at least $800 a year, until it is officially dissolved (i.e.: notice of cancellation/dissolution properly filed with the California Secretary of State). The FTB may come after members (including you) personally, if it can prove that the failure to pay was due to your negligence. Talk to a CA-licensed EA/CPA about how to resolve this. Otherwise, at least from what you've described, there were no other taxable events. LLC is a disregarded entity, so the IRS doesn't care about it much anyway (unless someone was stupid enough to elect it to be taxed as a corporation, that is). Keep in mind that when in doubt - you are always better off with a professional (a CPA/EA licensed in your State) advice.
Unfortunately, the tax system in the U.S. is probably more complicated than it looks to you right now. First, you need to understand that there will be taxes withheld from your paycheck, but the amount that they withhold is simply a guess.  You might pay too much or too little tax during the year.  After the year is over, you'll send in a tax return form that calculates the correct tax amount.  If you have paid too little over the year, you'll have to send in the rest, but if you've paid too much, you'll get a refund.  There are complicated formulas on how much tax the employer withholds from your paycheck, but in general, if you don't have extra income elsewhere that you need to pay tax on, you'll probably be close to breaking even at tax time. When you get your paycheck, the first thing that will be taken off is FICA, also called Social Security, Medicare, or the Payroll tax.  This is a fixed 7.65% that is taken off the gross salary.  It is not refundable and is not affected by any allowances or deductions, and does not come in to play at all on your tax return form. There are optional employee benefits that you might need to pay a portion of if you are going to take advantage of them, such as health insurance or retirement savings.  Some of these deductions are paid with before-tax money, and some are paid with after tax money. The employer will calculate how much money they are supposed to withhold for federal and state taxes (yes, California has an income tax), and the rest is yours. At tax time, the employer will give you a form W-2, which shows you the amount of your gross income after all the before-tax deductions are taken out (which is what you use to calculate your tax).  The form also shows you how much tax you have paid during the year. Form 1040 is the tax return that you use to calculate your correct tax for the year.  You start with the gross income amount from the W-2, and the first thing you do is add in any income that you didn't get a W-2 for (such as interest or investment income) and subtract any deductions that you might have that are not taxable, but were not paid through your paycheck (such as moving expenses, student loan interest, tuition, etc.)  The result is called your adjusted gross income. Next, you take off the deductions not covered in the above section (property tax, home mortgage interest, charitable giving, etc.).  You can either take the standard deduction ($6,300 if you are single), or if you have more deductions in this category than that, you can itemize your deductions and declare the correct amount. After that, you subtract more for exemptions.  You can claim yourself as an exemption unless you are considered a dependent of someone else and they are claiming you as a dependent.  If you claim yourself, you take off another $4,000 from your income. What you are left with is your taxable income for the year.  This is the amount you would use to calculate your tax based on the bracket table you found. California has an income tax, and just like the federal tax, some state taxes will be deducted from your paycheck, and you'll need to fill out a state tax return form after the year is over to calculate the correct state tax and either request a refund or pay the remainder of the tax.  I don't have any experience with the California income tax, but there are details on the rates on this page from the State of California. Well, that's probably not even all of it. If that stranger did his taxes properly, then he already paid about a third of it to the government because wherever he got it from it was income for him and thus it must have been taxed. Now, the remainder is in your hands and yes, according to US law it is now your income and so now you too, must pay about a third of it to the government, and yes you are supposed to explain where it came from. Be careful giving it to somebody else or it'll be taxed yet again. disclaimer: I am not a US citizen "Hearing somewhere is a level or two worse than ""my friend told me.""  You need to do some planning to forecast your full year income and tax bill. In general, you should be filing a quarterly form and tax payment. You'll still reconcile the year with an April filing, but if you are looking to save up to pay a huge bill next year, you are looking at the potential of a penalty for under-withholding.  The instructions and payment coupons are available at the IRS site.  At this point I'm required to offer the following advice - If you are making enough money that this even concerns you, you should consider starting to save for the future. A Solo-401(k) or IRA, or both. Read more on these two accounts and ask separate questions, if you'd like." The IRS can direct your refund towards repayment of your unpaid taxes either on Federal or State/Local level. Whether it will depends on whether the State of New York will ask for it. Generally, if you owe taxes to New York for this year only, you would expect them to wait for you to file your State tax return and pay the taxes owed. If you don't - I'm pretty sure that the next year refund from the IRS will go directly to them. 75k is short of the 'highly compensated' category.  Most US citizens in that pay range would consider paying someone to do their taxes as an unnecessary expense.  Tax shelters usually don't come into play for this level of income.  However, there are certain things which provide deductions. Some things that make it better to pay someone:   Use the free online tax forms to sandbox your returns.  If all you're concerned about is ensuring you pay your taxes correctly, this is the most cost efficient route. If you want to minimize your tax burden, consult with a CPA.  Be sure to get one who is familiar with resident aliens from your country and the relevant tax treaties. The estimate you're looking at may be the withholding, of which you may be eligible for a refund for some part of that withholding.   Tax treaties likely make sure that you get credit on each side for the money paid in the other.  For example, as a US citizen, if I go to Europe and work and pay taxes there, I can deduct the taxes paid in Europe from my tax burden in the US.  If I've already paid more to the EU than I would have paid on the same amount earned in the US, then my tax burden in the US is zero.  By the same token, if I have not paid up to my US burden, then I owe the balance to the US.  But this is way better than paying taxes to your home country and to the host country where you earned the money. "(Insert the usual disclaimer that I'm not any sort of tax professional; I'm just a random guy on the Internet who occasionally looks through IRS instructions for fun. Then again, what you're doing here is asking random people on the Internet for help, so here goes.) The gigantic book of ""How to File Your Income Taxes"" from the IRS is called Publication 17. That's generally where I start to figure out where to report what. The section on Royalties has this to say: Royalties from copyrights, patents, and oil, gas, and mineral properties are taxable as ordinary income. In most cases, you report royalties in Part I of Schedule E (Form 1040). However, if you hold an operating oil, gas, or mineral interest or are in business as a self-employed writer, inventor, artist, etc., report your income and expenses on Schedule C or Schedule C-EZ (Form 1040).  It sounds like you are receiving royalties from a copyright, and not as a self-employed writer. That means that you would report the income on Schedule E, Part I. I've not used Schedule E before, but looking at the instructions for it, you enter this as ""Royalty Property"". For royalty property, enter code “6” on line 1b and leave lines 1a and 2 blank for that property. So, in Line 1b, part A, enter code 6. (It looks like you'll only use section A here as you only have one royalty property.) Then in column A, Line 4, enter the royalties you have received. The instructions confirm that this should be the amount that you received listed on the 1099-MISC. Report on line 4 royalties from oil, gas, or mineral properties (not including operating interests); copyrights; and patents. Use a separate column (A, B, or C) for each royalty property. If you received $10 or more in royalties during 2016, the payer should send you a Form 1099-MISC or similar statement by January 31, 2017, showing the amount you received. Report this amount on line 4.  I don't think that there's any relevant Expenses deductions you could take on the subsequent lines (though like I said, I've not used this form before), but if you had some specific expenses involved in producing this income it might be worth looking into further. On Line 21 you'd subtract the 0 expenses (or subtract any expenses you do manage to list) and put the total. It looks like there are more totals to accumulate on lines 23 and 24, which presumably would be equally easy as you only have the one property. Put the total again on line 26, which says to enter it on the main Form 1040 on line 17 and it thus gets included in your income." First, if you haven't seen it yet, check out the IRS Taxpayer Advocate Service's I Don't Have My Refund page.  It discusses different things that can go wrong with receiving your refund and what to do about it. From your post, it sounds like you've tried all of the normal things to do, and you've tried calling in to the IRS.  What you might not know is that there are local IRS offices that you can visit and talk to a real person face-to-face.  Hopefully, you'll find someone helpful there who can either explain to you what is going on or put you in touch with someone who can help.  To find your local IRS office, go to the Contact Your Local IRS Office page and click on the Office Locator button.  Office visits are generally by appointment only, so you'll need to call the number for the office you want to visit and make an appointment. Alternatively, if you can't get anywhere with the IRS, you could contact the Taxpayer Advocate Service, which is an independent organization within the IRS that exists to help people with disputes with the IRS, and they have an office in every state.  You could try contacting them and seeing if they can help you with your issue. To answer your question about this year's tax return: At least for the federal return, your refund from last year does not really affect this year's tax return.  You should be able to file this year's return no matter what happens with last year's refund.  That having been said, you should get the refund matter straightened out as soon as you can. Good luck. You pay it this tax year.  Whether that's now due to W-2 withholding, or later with your 1040 next year, or with your 1040-ES all depends on your particular situation. It's been a couple years since I worked on Transfer Pricing project.   It makes sense though. I'd imagine that's why Texas and Florida are doing, tax wise, so much better than California and other high tax states. He should look into the Voluntary Disclosures Program. He will have to keep up to date with his taxes thereafter, but the outcome will likely be better than if they discover he hasn't been filing before he discloses it. Multistate Impact of the American Taxpayer Relief Act of 2012  In general, states with rolling conformity will follow this change. States with specific date conformity will continue  to follow the date of conformity currently in effect and will not follow the change. A few states may have their own  QSBS rules and will not conform to or be impacted by this provision of the Act. The chart that follows summarizes  these principles as applied to the enumerated states:  STATE: QSBS Exclusion Conformity:  California statutes refer to the IRC QSBS provisions but modify and limit their  applicability, and would not be impacted by this provision of the Act. However, California’s provisions were ruled unconstitutional in recent litigation and the California Franchise Tax Board has recently taken the position that gain exclusions  and deferrals will be denied for all open tax years. Florida Florida does not impose an income tax on individuals and therefore this provision of  the Act is inapplicable and will have no impact.  Illinois Due to its rolling conformity, Illinois follows this provision of the Act.  Because New York effectively provides for rolling conformity to the IRC, through  reference to federal adjusted gross income as the state starting point, New York  effectively follows this provision of the Act.  Texas does not impose an income tax on individuals "I'll add a bit to Paul's excellent write up. Foreign Earned Income Exclusion (form 2555): notice the earned there. It doesn't exclude capital gains, interest, dividends, and basically everything that is not salary. You pay US taxes on it from the first cent. Foreign tax credit - foreign tax credit (form 1116) doesn't reduce your US tax dollar for dollar (even though it may appear that it does from the generic explanations). By using this form you may end up accumulating unused credit while still paying double taxes at the same time. Happened to me. Thank Congress for the logical and reasonable US tax laws. New FATCA form 8938: as opposed to FBAR (that goes to the FinCEN in the Treasury), this one goes to the IRS. it contains very similar info, but the threshold requirements are different. You may have to file FBAR, but not these, or you may have to file both. Being an American citizen, some European banks will refuse to provide services to you. Again, thank Congress for FATCA. It requires foreign banks to enforce US tax regulations on US citizens, and banks that won't will get penalized in the US. Many banks refuse to provide services to Americans because of that because what IRS requires is illegal in most countries. Some countries (like UK and some other EU countries) have signed treaties with the US to resolve this, but many haven't. Currency conversion - as I commented to Paul, you convert the amounts when you receive them, which may have your fixed EUR salary be converted to different dollar amounts every time. You need to make sure you do it right. Pensions, savings, investments - if you're doing these in non-US instruments prepare to be penalized. US taxes foreign investments much more aggressively than domestic. If you're investing in indexes/mutual funds, or you're a principle in a corporation, or you create a pension account - you'll get hit by additional reporting requirements and tax. Tax treaties - the US has tax treaties with many EU countries, and equalization treaties with some. The tax treaties affect the standard tax treatment by the US and some of the ""generic"" info you got here may not apply because of a tax treaty, and some other rules may apply. Equalization treaties work similarly with regards to the Social Security. Bottom line, and I know Paul disagrees with me on this - talk with a US-licensed adviser in the country you're going to. It is very important for your tax adviser to know the relevant treaty (and not read it the first time when you call him), and to understand each and every financial instrument in your country. Missing piece of paper in your tax return can cost you thousands of dollars in penalties (not exaggerating, not filing form 3520 triggers a $10000 penalty, even if there's no tax) and additional taxes." Real world case: IRS:  You owe us $x.  You didn't report your income from job y. My mother:  I didn't work for y.  I don't even know who y is. IRS:  If the W-2 is wrong, talk to them to get it fixed. My mother:  I can't find y.  Please give me an address or phone. IRS:  We can't.  You talk to them and get it fixed. I know this dragged on for more than a year, they never mentioned the final outcome and they're gone now so I can't ask. Using the advice of @user102008 , I read-through the booklet of State2, and it said the following: ... so I'm not going to include my State1 W-2s. "If you live outside the US, then you probably need to deal with foreign tax credits, foreign income exclusions, FBAR forms (you probably have bank account balances enough for the 10K threshold) , various monsters the Congress enacted against you like form 8939 (if you have enough banking and investment accounts), form 3520 (if you have a IRA-like local pension), form 5471 (if you have a stake in a foreign business), form 8833 (if you have treaty claims) etc ect - that's just what I had the pleasure of coming across, there's more. TurboTax/H&R Block At Home/etc/etc are not for you. These programs are developed for a ""mainstream"" American citizen and resident who has nothing, or practically nothing, abroad. They may support the FBAR/FATCA forms (IIRC H&R Block has a problem with Fatca, didn't check if they fixed it for 2013. Heard reports that TurboTax support is not perfect as well), but nothing more than that. If you know the stuff well enough to fill the forms manually - go for it (I'm not sure they even provide all these forms in the software though). Now, specifically to your questions: Turbo tax doesn't seem to like the fact that my wife is a foreigner   and doesn't have a social security number. It keeps bugging me to   input a valid Ssn for her. I input all zeros for now. Not sure what to   do. No, you cannot do that. You need to think whether you even want to include your wife in the return. Does she have income? Do you want to pay US taxes on her income? If she's not a US citizen/green card holder, why would you want that? Consider it again. If you decide to include here after all - you have to get an ITIN for her (instead of SSN). If you hire a professional to do your taxes, that professional will also guide you through the ITIN process. Turbo tax forces me to fill out a 29something form that establishes   bonafide residency. Is this really necessary? Again in here it bugs me   about wife's Ssn Form 2555 probably. Yes, it is, and yes, you have to have a ITIN for your wife if she's included. My previous state is California, and for my present state I input   Foreign. When I get to the state tax portion turbo doesn't seem to   realize that I have input foreign and it wants me to choose a valid   state. However I think my first question is do i have to file a   California tax now that I am not it's resident anymore? I do not have   any assets in California. No house, no phone bill etc If you're not a resident in California, then why would you file? But you might be a partial resident, if you lived in CA part of the year. If so, you need to file 540NR for the part of the year you were a resident. If you have a better way to file tax based on this situation could you   please share with me? As I said - hire a professional, preferably one that practices in your country of residence and knows the provisions of that country's tax treaty with the US. You can also hire a professional in the US, but get a good one, that specializes on expats."
