It's just FUD. In 2007, LM was awarded a minor contract to help update the IRS' technology systems: (1)to modernize the notice system (referring to notices received by taxpayers under audit or for penalty assessments) and the publication system (the pdf's available on the IRS website. (See http://www.lockheedmartin.com/us/news/press-releases/2007/oc...)

Lockheed Martin was not involved in helping the IRS design or update its return processing system (including e-file). A contract of that magnitude would be worth billions, not the $36 million LM was paid for the work above.

Apparently, yes.

Yes. It seems like they've been involved since at least 1996 or so (probably way earlier than that).
