Q. With that in mind, do I now need to legally issue a 1099 from me personally to the business to removed the 1099-K issued to my personal SSN and show the income to the business EIN?
A. No.
A single member LLC is a Pass Thru Entity. All income is reported on Schedule C. It doesn't matter whether the payment processing firm issued the 1099-K in your SS# or the EIN.
