Should a sole proprietor also become an LLC? I am a startup and what are the benefits?
If you have any credit or outstanding liabilities under your current EIN, I would apply for a new EIN.
I also recommend going the LLC route. DBAs don’t give you any protection and retail = public and public = potential lawsuits even if you do nothing wrong. In most states allow you to do without all that much paperwork. In NY, for example, you can do all this on-line and this is something you can do yourself if you will be the only owner, know as a “single member”. Although, in NY I do recommend hiring someone to help fulfill the publication requirement just to save you time and leg-work.
If there is more than one owner – known a as ‘multi-member’ LLC, then a lawyer would be useful in least to have the operating agreement created but the LLC is still something you can do yourself.
