Filing 1040-NR when I have been outside the US the entire year?
Yes, you can still file a 1040nr. You are a nonresident alien and were:  engaged in a trade or business in the United States Normally, assuming your withholding was correct, you would get a minimal amount back. Income earned in the US is definitely Effectively Connected Income and is   taxed at the graduated rates that apply to U.S. citizens and resident aliens. However, there is a tax treaty between US and India, and it suggests that you would be taxed on the entirety of the income by India. This suggests to me that you would get everything that was withheld back.
"From your description, the taxes may have been withheld incorrectly. You were most likely a nonresident alien during your entire stay. ""Teachers and trainees"", which include anyone on J status who is not a student, are ""exempt individuals"" (exempt from the Substantial Presence Test) unless they have already been an exempt individual during any part of 2 of the prior 6 calendar years. So if you haven't been in the U.S. as an F-1, J-1, etc. for at least 6-7 years before you came on J-1 this time, the first two calendar years of your time on J-1 this time does not count towards the Substantial Presence Test. You said you were there for 18 months. That stretches over either 2 or 3 calendar years. The first two calendar years of it would be exempt from the SPT; even if it stretched into a third calendar year, an 18-month period could not stretch for more than 6 months into a 3rd calendar year; so even in that case you would still not meet the Substantial Presence Test for the 3rd year. Since you do not meet the Subtantial Presence Test during any of those years, you were a nonresident alien for all of those years (unless you decided to file jointly with a resident spouse or something). Nonresident aliens on J-1 are exempt from FICA taxes (Social Security tax and Medicare tax) for employment as a researcher that you were authorized to do on your J-1. They should not have withheld FICA taxes from you. You should have informed them at the beginning when you initially noticed that they did, because it is a huge pain to get it back afterwards. For FICA taxes withheld in error, you can first ask the employer to refund them; and, if that fails, get a written statement of their refusal and then file Form 843 and Form 8316 with the IRS. However, given that IRS is very underfunded these days, expect it to take a long time to hear back if you ever hear back." "If you are in the US, you legally must file taxes on any income whatsoever.  How much you will pay in taxes, if any, will depend on your total taxable income. Now, for small transactions, the payments are often not reported to the IRS so some people do not file or pay.  The threshold at which they payer is required to send a 1099 to the IRS is $600.  Patreon considers each donation a separate transaction and therefore does not send a 1099 to the IRS unless you make more than $20,000 in a calendar year.  If they do not report it, the IRS will not know about it unless they audit you or something.  However, you are technically and legally responsible to report income whether the IRS knows about it or not. -------- EDIT ------- Note that the payer files a 1099, not the recipient. In order to report your patreon income you will either use schedule C or add it to the amount on 1040 line 21 (""other income"") depending on whether you consider this a business or a hobby.  If it's a business and it's a lot of money you should consider sending in quarterly payments using a 1040-ES in order to avoid a penalty for too little withholding." "By living in Sweden and having a Swedish personal identification number (personnummer), you are required to declare your entire worldwide income for tax purposes with the Swedish tax authorities, Skatteverket. It would seem to not make any difference if some of that income is kept outside of Sweden. A company that has no permanent base of operations within Sweden should not deduct any preliminary taxes for an employee that lives in Sweden. Rather, the employee should apply for ""special A tax"" (""SA"" tax status), and pay the taxes that, had the company had a permanent base of operations in Sweden, the company would have paid. The information available on the tax authority's web site in English seems limited, but the relevant page in Swedish in your situation is very likely Lön från utländska arbetsgivare utan fast driftställe i Sverige. There is a summary at Paying taxes – for individuals. Particularly do note the summary section: When staying for at least six months, you are considered as resident in Sweden for tax purposes, and are liable for taxation in Sweden on all of your worldwide income. You must also file a Swedish income tax return. Your tax return must be filed no later than May 2nd of the year after the fiscal year. as well as that: If you stay in Sweden for a continuous period of at least six months you are considered to be resident in Sweden. /.../ As a resident you are liable for taxation in Sweden on all of your worldwide income. In some cases a tax treaty with with your ordinary country of residence  may limit the Swedish taxation. /.../ For a more detailed answer, including which exact forms you need to fill out and what data is needed, I strongly recommend that you either contact Skatteverket (they are usually quite nice to deal with, and they tend to realize that everyone benefits from getting the tax paperwork and payments right from the beginning), or find an attorney specializing in Swedish tax law. They even point out themselves that (my emphasis): the practical applications of these rules are relatively complicated and for more information you can contact the Tax Information (“Skatteupplysningen”) at 0771 567 567." Generally stock trades will require an additional Capital Gains and Losses form included with a 1040, known as Schedule D (summary) and Schedule D-1 (itemized).  That year I believe the maximum declarable Capital loss was $3000--the rest could carry over to future years. The purchase date/year only matters insofar as to rank the lot as short term or long term(a position held 365 days or longer), short term typically but depends on actual asset taxed then at 25%, long term 15%.  The year a position was closed(eg. sold) tells you which year's filing it belongs in. The tiny $16.08 interest earned probably goes into Schedule B, typically a short form. The IRS actually has a hotline 800-829-1040 (Individuals)  for quick questions such as advising which previous-year filing forms they'd expect from you.  Be sure to explain the custodial situation and that it all recently came to your awareness etc. Disclaimer: I am no specialist. You'd need to verify everything I wrote; it was just from personal experience with the IRS and taxes. To start with, I should mention that many tax preparation companies will give you any number of free consultations on tax issues — they will only charge you if you use their services to file a tax form, such as an amended return. I know that H&R Block has international tax specialists who are familiar with the issues facing F-1 students, so they might be the right people to talk about your specific situation. According to TurboTax support, you should prepare a completely new 1040NR, then submit that with a 1040X. GWU’s tax department says you can submit late 8843, so you should probably do that if you need to claim non-resident status for tax purposes. I'm not sure why you're confusing the two unrelated things. 1040ES is your estimated tax payments. 941 is your corporation's payroll tax report. They have nothing to do with each other. You being the corporation's employee is accidental, and can only help you to avoid 1040ES and use the W2 withholding instead - like any other employee. From the IRS standpoint you're not running a LLC - you're running a corporation, and you're that corporation's employee. While technically you're self-employed, from tax perspective - you're not (to the extent of your corporate salary, at least). Do I pay tax to the US and then also pay it in India for my income, or   does my American partner, who holds 15% of the monthly income, pay tax   in the US for his income? Of course you do, what kind of question is this? You have income earned in the US by a US entity, and the entity is taxed. Since LLC is a disregarded entity - the tax shifts to you personally. You should file form 1040NR. You should also talk to a tax professional who's proficient in the Indo-US tax treaty, since it may affect your situation. If i am not wrong, any business activities such should be declared on Year End Tax filing. If your friend is going to own that website either it is commercial or nonprofit, he has to declare in the year end taxation.
