Can anyone tell me when it is necessary to make an adjustment on line 3 for self employed retirement plans such as SEP, Simple, or qualified plans?
My software gives me a diagnostic that it may be necessary, but I cannot find mention of when or why in the 6251 instructions. The software provides a sub schedule that includes the items mentioned in the instructions for line 3, and adds other items such as the above, self employed health insurance and others.
Sure would be good to know I am not missing something here.
