Common Scenarios for Multiple Businesses Under One LLC

Can I use one EIN for multiple businesses under an LLC?

Sarah runs both a graphic design studio and a print-on-demand store. She wondered if she needed separate tax IDs. According to IRS Publication 1635 (2023), a single-member LLC can use one EIN for multiple DBAs (Doing Business As) if they're part of the same legal entity.

1. File a DBA for each business name with your state (costs $10-$100)
2. Use your existing EIN for all tax filings
3. Keep separate financial records for each DBA
