@codewarrior_777 as a wage earner ( employee with taxes withholding by employer ) you cannot use your business EIN -- your tax account with the IRS / State is under your personal TIN ( Tax ID )-- SSN in this case. If you are a Non-Employee / Self-employed you still have to use your SSN as TIN. On the other hand, if you are an employee of your own entity ( C-Corp. S-Corp, LLC Partnership etc. ) then you use the entity's EIN, because it is the entity that is providing the service through an employee ( and the entity pays you as an employee or as non-employee ).
Does this make sense ? Is there more I can do for you ?
