Inquiry Regarding Tax Filing Options for Online Business Targeting Foreign Market

[mama A]

Hi, 

I'm launching an online business targeting a foreign market initially, with potential expansion to the US.

Q1: Should I register a company in the foreign country or file taxes in the US?

Q2: If US filing is advised, should I use Schedule C for self-employed taxes, or consider another business structure?

Q3: Additionally, if my business earns no income in the first year but incurs $1000 in expenses, can these expenses be claimed on Schedule C to offset my federal or state tax returns?"

Thank you so much
