For the single member LLC treated as a disregarded entity for tax purposes, the EIN is your SSN.  

Please disregard my comments in the previous paragraph.

Shouldn't be any other tax issues as LLC's are treated as disregarded entities and are taxed on a "flow through" basis by the IRS.  

I can't get a straight answer and I'm on the verge of requested an opinion letter from the IRS directly.Here's the situation -I have a single member LLC (disregarded) that wholly owns the following:Three rental propertiesA second single member LLC (disregarded) not involved in real estateA third single member LLC (disregarded) - construction companyHow do you report this on your 1040?

You don't just stand up in front of a judge and say, "I'm a smart lawyer, Your Honor, and I think you should disregard the laws of this state and hold the owner of this LLC personally liable."

We want to be able to consider the LLC a disregarded entity.a) Since CA is a community-property state, can we be a disregarded entity (for tax purposes) with 2 members?

However, a single member LLC/disregarded entity and/or a land trust should not pose any problems for you since disregarded entities are still treated as if the underlying owners own the property (i.e., you and your wife). 

LLCs can check the box for S-Corp election and pay employees W-2 salaries to offset profits subject to self-employment taxation that would be on Schedule C self-employment income as a disregarded entity / sole proprietorship.9.  

Asset protection is a must even if it's disregarded by many as a not-so-important investment.  

Single member LLC's are still taxed under your personal tax return as they are disregarded entities.
