Yes it’s been really hard to get help, some of them have told me to talk to a immigrant attorney (about my taxes), of course inmigrantes attorney told me to talk to a taxers accountant, then a taxers accountant told me I had to open a LCC, and he wanted to help me to open a busssines so I was suspicious. Then another was supposed to called me , never called
I’ve been back in forth for years
@Isi26 based on what you have posted so far ( nationality , entry to US, type of self-employment etc. ) , and generally agreeing with all that my colleague @Opus 17 has posted earlier for US federal purposes :
(a) you need to prepare a return on form 1040 ( TurboTax supports this ), you report your global income on Schedule-C , deducting allowable expenses --- About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) | Internal Revenue Service
Pay good attention to all the instructions for Schedule-C
(b) Note that because this is self-employment income (active income ) you are subject to Self-Employment Tax ( SECA at 15.3% of approx 92% of net-income from Schedule-C ) . However, because Chile and US Social Security has a "Totalization Agreement", you will need to participate only in one country. --See here -->U.S. International SSA Agreements | International Programs | SSA
(c) Once you are all done ( note for making software happy you will need to use a dummy Social Security Number like 234-84-5000), print out the return, sign date, replace the dummy SSN with " N R A".
(d) Now go to IRS website and download form W-7 and its instructions. Fill out the form, attach all the documents asked for .
(e) Send the whole package to IRS . This should result in IRS retroactively issuing you an ITIN ( since you are not eligible for SSN ).
(f) In future years you can file normally using the issued ITIN.
(g) Your foreign taxes paid to Chile, may be eligible for Foreign Tax credit.
(h) Given that you have never filed a US return, you probably should consider TurboTax full service or see a tax professional; familiar with International Tax, Schedule-C and Totalization agreement. You can take a printout of this response ( the whole thread ) along with you .
Is there more I can do for you ?
