I have a client who has a 2009 NOL which we are carrying back to 2005 under the special rules for 2008 and 2009. Most of the loss was carried forward from 2008. In 2005 he was subject to alternative minimum tax. Now the IRS wants me to send a worksheet showing the AMT NOL calculation for 2005. My software does not support this calculation. I have called three different numbers at the IRS and they say there is no worksheet.

I appreciate any information you have or any source that explains in plain English how to prepare the worksheet.
