This summer 2016, I was hired as a software engineer for an internship in California. I am a student and came under a J-1 visa.
I fail the SPT so I am a non-resident alien (NRA).
I was paid as an independent contractor (although I fell more likely under the category of an employee ...)
I was paid $3000/month for 2 months without any tax withholding (I believe my employer should have done tax withholding but they didn't)
No tax-treaty applies to my case and I do not wish to claim any tax exemption.
If I am correct, in this bracket, I should pay no Californian State tax but 10% federal taxes.
My understanding is that I have to fill the form 1040NR and state my income as a business income on line 13.
I would also have to fill Schedule C, but I do not have any business (so no EIN) and I do not have any SSN either.
What should I do? I would happily pay my $600 of taxes but it seems so complicated.
