Hi Kirt,If you mean Social Security Disability Insurance - it looks like once you qualify the amount you can earn in a month and still receive benefits is $900 per month in 2007 and $940 per month in 2007. You should check the Social Security web site for more detail - there are also special situations.http://www.ssa.gov/dibplan/dqualify.htm
Found more detail here - apparently there is a trial period when you can make more and then the income limits kick in:http://ssa-custhelp.ssa.gov/cgi-bin/ssa.cfg/php/enduser/std_adp.php?p_faqid=317
