Arizona EIN LLC Husband and Wife Multi vs Single Member

[Derek Steinmetz]

My wife and I live in Arizona (a community property state) and created an LLC where we are both equal members. I was going onto the IRS website this morning to get an EIN and one of the questions was:

You are husband and wife residing in a community property state and the only two members of a Limited Liability Company (LLC).

Under Revenue Procedure 2002-69, you have the option of treating the LLC as a
multi-member LLC or as a single-member LLC. 

The question is which one is correct for the sake of Taxes.  We currently file married joint return.

Thanks.
