W8 or W9 for non-resident non-taxable sole prop owned LLC
I am a non-citizen, non-resident sole proprietor of an LLC. My LLC has an EIN, but no employees. I set up the LLC to be able to bill clients in the US for services rendered 100% remotely from overseas (not necessarily my home country). I am pretty confident I am not liable to pay taxes in the US for the income earned through the LLC because I did not have a substantial presence in the US (183 days in the past 3 years), and I do not operate an office or warehouse, sell any products or have any employees or sales agents in the country, so the revenue of the LLC is not "connected" to work done in the US. This month I decided to start billing my US client through my LLC this month and they came back to me with a W9 form. I wonder whether this is the form I should fill, as a US LLC, or rather as a non-taxable non-resident I should ask for a W8. In the second case, does this create some sort of reporting between the IRS and the authorities of my country? I understand this is professional CPA advise I am asking for, so I am totally willing to pay for a full consultation, and for further services.
