How do I set up a LLC with multiple DBAs underneath? -

Is it possible to roll all the taxes under the llc?

Sure. You can have a single LLC operate under a number of different trade names. Just set up the LLC. Then you have to create the DBA s. That process varies from jurisdiction to jurisdiction, but it usually involves some sort of filing, registration and publication saying something like Bongo LLC is hereby operating under the fictitious name Oogabooga. You can do this for any number of fictitious names. You also might want to create registered trademarks or service marks. That is a bit more complicated. In the US, it involves filing with the US Patent and Trademark Office, a fairly frustrating process.Since you are operating under a single LLC, that entity will be the only tax-filing entity.
