@onyxrubyrose30 , while my colleague @xmasbaby0 has provided you with an excellent response and included a number of references, I just wanted to complete this reading list with something from the IRS --------------> About Form W-9, Request for Taxpayer Identification Number and Certification | Internal Revenue Serv....
This covers the current form and instructions thereof. The form itself also covers a lot of the instructions on how to fill out the form.
The assumption here is that you are a US person ( citizen/GreenCard/Resident for Tax purposes ) and that your actual work ( for this income stream) is actually performed in the US.
