Publication 256 IS available now.  My Senator, Tammy Baldwin's, office sent me a copy yesterday.  Lacerte is saying that the software cannot be changed for the 60% cap until the IRS issues its non-authoritative publication; but that has happened.  I'm very frustrated.  I have a 100-year old client to whom the 60% cap applies, and Lacerte keeps generating a critical diagnostic saying that it cannot implement the change.  I don't like to keep a 100-year old waiting!
