Re: Single Member LLC - EIN/Tax ID still required or SS#? Oct 23, 2008 10:32 AM

As GrowthCurve quoted, the LLC is taxed by the IRS as a pass-through entity (same as a sole proprietorship) unless you elect for it to be taxed as a corporation. So like a sole proprietorship, you
can operate on just your SSN. However . . .
Since you went to all the extra expense and trouble to form an LLC instead of sole proprietorship in the first place, I'd assume there are reasons (that either now or someday involve the business entity being legally separate from you personally). So the business really needs its own identification number -- i.e., the EIN.
My suggestion is to apply for one now (you can do it on-line in minutes), and start using it in all situations for the business entity. As a single member LLC, you will still have to provide your SSN along with the EIN (e.g., to the bank, creditors, etc.) -- but unless the business
has an EIN, it's just an extension of you for all practical purposes (in which case, you might as well have formed a sole proprietorship).
Hope that helps. Welcome to the community and best wishes.
