See the new attachment of the Form 4491W problems with state answers. Thanks to Jon Christopherson for updating this.
See the attachments below for answers to exercises and comprehensive problems in the Publications 4491W. Most of the exercises are relatively short, so I suggest you try to do the problem on TaxWise training or Practice Lab before you look up and check the answer. I also suggest that you follow pages 2 and 3 of the intake sheet to do a personal quality review ... best again if you do this before looking at the answer.
Keep a copy of the Publication 4012 close. I like to have a pdf electronic version of the Pub 4012 on my pc desktop, then use the search function to quickly find reference of inputs and topics (CNTL-F then input a key word to search, i.e. search on "IRA Distribution" or "railroad retirement").
The comprehensive problems in the intermediate course (Graham) and advanced course are long and involved. Here you might want to checkup on yourself as you go along. If you are having problems, ask for help from your site, local, or district coordinator or me. Any of us would like to help you.
