Hello, my name is ***** ***** I will try to help you. Please remember I just report or interpret the law, so the outcome may not be what you hoped for.
I assume your doctors with multi-state licenses practice in each of the sates in which they are licensed and are paid according to the state in which they see the patient. the simplest solution may be to have each of the practitioners create a single member LLC for all but one of the state states in which they operate. They can bill in their own name under their Tax ID (SS#) in one state and through the LLC which can have its own tax ID # ***** from the professional's SS#. This will add cost for forming the LLCs and the annual fees in each state but it will solve your billing problem. Since they are single member LLCs the income and expenses are put on the individual's tax return under Schedule C so you do not have to file a separate tax return for each LLC.
If I have answered all your questions, please positively rate my answer as that is how I receive credit. If you have more questions, please let me know. If the answer was especially helpful you can provide a bonus.
The concern I have about not using an LLC and just getting a tax ID number as a sole proprietor, is I am not sure you can use two IDs number for the same business. That is why I suggested the LLC.
