Let me bounce this off you guys and see if I'm interpreting it right this is from
https://www.irs.gov/businesses/small-businesses-self-employed/do-you-need-a-new-ein :
Sole Proprietors
You will be required to obtain a new EIN if any of the following statements are true.
•You are subject to a bankruptcy proceeding.
•You incorporate.
•You take in partners and operate as a partnership.
•You purchase or inherit an existing business that you operate as a sole proprietorship.
You will not be required to obtain a new EIN if any of the following statements are true.
•You change the name of your business.
•You change your location and/or add other locations.
•You operate multiple businesses.
It seems like the last line basically says I can have multiple ways of earning income(multiple business) under the same EIN so I should be fine. Am I reading that right?
Edit: Also if the side income is made out to me and not the business, will that be an issue?
