The court reminded the taxpayer that he has an obligation to review his return to be sure it is complete. My due diligence reminder for this one is that practitioners should not give clients tax returns so close to the filing deadline that they do not have time to review them. Practitioners should also remind clients of the need to review the return and that they are responsible for its contents. And, of course, practitioners should review their preparation and review processes to be sure information provided by clients is not omitted. Perhaps one element of a solution to that one would be to have the client tell the preparer how many information returns they are providing.
Due diligence obligations grow more complex and lengthy as the tax system becomes more complex. So certainly, an area where ever more time and attention needs to be paid.
