A source of seminars on almost any tax or accounting subject is available from Bob Jennings at his Tax Speaker site.  If you go to the NCSA website, then go to Useful Links, it is there.  Take that link to the Tax Speaker website and see the extensive catalogs. 

Note that if you select a seminar, the price is crossed out and a lower price applies.  We get a discount on the seminars by going to his website through our website and NCSA gets some money.  However, the 1040 class is not discounted.
