I have a US and Italian citizen and I live in Italy and pay taxes here.
Recently I worked for a US company as a freelancer providing a website update.
I sent them the invoice under my name but they are asking me to compile the the W-9 form.
I compiled the W-9 form this way:
- CHECKED Individual/sole proprietor
- Social Security Number
Should I compile that form?
Do I have to pay tax in Italy and in US for that job?
