Unbelievable one, but yes.  Just this morning, Lacerte told me to file all of my extensions by May 17th as the software is not going to allow us to file extensions after that date even though ours are not due until June 15th.  And that any payments need to be made by check or on the IRS website if you want them to be made after June 15th.  So disappointed in Lacerte!  I plan to follow up with a few colleagues to find out how Thomson Reuters and CCH are handling this and I'll let you know.
