Sometimes, forming one business just isn’t enough. When you have several amazing business ideas that can change the world, you might be tempted to form several LLCs at the same time. However, as you pursue the path of business ownership, several questions may arise. What type of business activity can I conduct with my LLC? How many different businesses can I operate under one LLC? Will a Series LLC work for me?
Depending on the scope of your individual businesses, the answers to your questions may vary. Operating multiple businesses under a single LLC is an option, but you may also want to consider a few alternatives. First, let’s review the basics.
Yes, you can operate multiple businesses under one LLC. This setup allows all business activities to be managed under a single legal entity, which can simplify administration and reduce formation costs. However, it’s important to understand that all operations under the LLC share the same legal and financial liability, meaning if one business faces a lawsuit or debt, the others could be affected.
To manage multiple businesses under one LLC, you generally have three options:

One common way to run multiple businesses under one LLC is by registering multiple DBAs, or “doing business as” names. A DBA allows your LLC to operate under a different business name without creating a separate legal entity. This is a great choice if your businesses are related or share the same ownership. It may also be simpler and less expensive than forming a separate LLC for each business. However, it is important to understand that a DBA does not provide separate liability protection. All DBAs still belong to the same LLC, which means all of your assets are legally connected. If one DBA faces a lawsuit or debt, the entire LLC could be affected.
Another option is to form a separate LLC for each business you operate. Instead of running multiple brands under one legal entity, each business has its own LLC, bank account, contracts, tax records, and liability protection. This structure can be especially helpful when the businesses are mostly unrelated. The biggest advantage is legal separation. If one LLC faces a lawsuit, the other LLCs are better protected. However, separate LLCs also come with more administrative work, including additional formation fees, annual reports, and compliance requirements. For many business owners, the decision comes down to balancing simplicity against stronger liability separation.
A Series LLC is a special type of LLC that allows one parent LLC to create separate internal divisions, called series. Each series can have its own assets, business purpose, and liability protection. This structure offers some of the liability separation of multiple LLCs while reducing the need to form and maintain several separate entities. The one caveat is that Series LLCs are more complex than standard LLCs and are not available in every state. Banks and courts may also handle them differently depending on the jurisdiction.
Choosing between multiple DBAs under one LLC, separate LLCs for separate businesses, and a Series LLC depends on your goals for your businesses. A simpler setup may work well for closely related or low-risk businesses, while separate entities may be better for businesses with different assets. Before deciding, consider how each option affects legal protection, taxes, costs, and future growth.
How many DBAs can an LLC have?
An LLC can technically have any number of DBAs under its umbrella. As long as each DBA is registered separately with the Delaware Division of Corporations and you pay a filing fee for each name, you can continue to add new DBAs.
Can two unrelated businesses be under one LLC?
Yes, but it may not always be the best choice. The main benefit is simplicity, as you only have one legal entity to form and maintain. However, the biggest downside is shared liability. If one business is sued or takes on debt, the other business could be affected because both are part of the same LLC. It could also be confusing for customers who are trying to research your business.
Can I add a new business to my existing LLC?
Yes, you can add new businesses to an LLC. You may also need to register a DBA if the new business will use a different public-facing name. If the new business is very different or higher-risk, forming a separate LLC may be better.
What states allow Series LLCs?
There are currently over a dozen different states that allow you to form a Series LLC. Delaware does allow them, and was even the first state to introduce the Series LLC structure back in 1996. Other states include Illinois, Texas, Nevada, and Wisconsin.
Can an LLC own another LLC?
Yes, an LLC can own another LLC. Such cases are referred to as a parent-subsidiary relationship, where the parent LLC holds ownership in a subsidiary LLC. In these scenarios, the parent will have control of the subsidiary’s operations while remaining a separate legal entity.

Luis said: Thursday, June 6, 2019Hola, si uno vive en otro país distinto de USA registra una LLC unipersonal en Delaware y bajo esa LLC quiere operar varios sitios web distintos uno de otros para e-commerce que vende a todo USA y el mundo, es necesario obtener un EIN para cada sitio y un DBA para cada sitio también? Ej: Mascotas.com / AsesoriosAutos.com / AlquilerDeCasas.com, etc Considerando su respuesta, cada sitio debería tener una cuenta bancaria diferente o la cuenta bancaria se abre para la LLC mas allá de los distintos sitios web que opere ? muchas gracias, saludos!
HBS Staff replied: Friday, June 7, 2019Hola! Muchas gracias por visitar nuestra pagina, es un placer asistir con sus preguntas. Una LLC puede tener mas de un sitio web bajo una LLC. Si es que va recibir pagos al nombre de distintos sitios web, quisa sea necesario obtener un DBA por medio de su jurisdiccion de operacion.
Normalmente, los clientes si obtienen el EIN, ya que es un requisito para la cuenta bancaria. El EIN es especifico a una LLC solamente.

Mary Kaeser said: Tuesday, July 17, 2018I’m a contract RN and I have an LLC for that business. I’m thinking about doing a Nursjng Agency job as a second job. Is it ok to use the same EIN number for both places since the both are nursing? What is I pick up a third nursing job, would that also be ok to use same EIN?
HBS Staff replied: Wednesday, July 18, 2018If you are using the same company name for all your businesses, then you can use the same EIN; howerver, if you have different names for your businesses, you will need to apply for additional EINs. Every company must have its own EIN.
Brandon Santee said: Thursday, May 17, 2018Does a LLC and A DBA require two separate EIN numbers?
HBS Staff replied: Monday, May 21, 2018When you apply for an EIN, there is a line on the application for a DBA, so you can name your DBA and your LLC on the same form, thereby only needing one EIN number.
