Filing 42 biz extensions for one client with lots of commercial real estate entities.  Cannot e-file MD, NY, NYC unless you correct almost every error in the return, which if we don't have info, is a zillion.  It's just a -0- extension.  MD even needs 8825 other expenses every line filled in (even with a -0-) for it to go through.  NY has tons of entries that when I go to prepare the actual returns I'll have to remember to undo the entries for stuff to transfer from Federal.  It should be a 2-minute extension but it's not.  Easier to go to state website and file that way without all this B.S. from P.S.
