I am in Texas and so are all of my clients (although one has Georgia sourced income.)  This is my first time dealing with federally declared disaster area filers of any kind.  Is it a good idea to go ahead and file extensions even though we have until June 15?   I know the extension applies to business returns normally due March 15 also.  But should I file extensions anyway (but leaving out payments for estimated balances due that would normally be made...?)  Is there a notation that should be made on the actual return when filed indicating a disaster area filer?   Any advice or suggestions?
