Doug Shulman's shop is getting $500 million of the $1 billion set aside for implementing ACA:
The money is only part of the IRS’s total implementation spending, and it is being provided outside the normal appropriations process. The tax agency is responsible for several key provisions of the new law, including the unpopular individual mandate. Republican lawmakers have tried to cut off funding to implement the healthcare law, at least until after the Supreme Court decides whether to strike it down. That ruling is expected by June, and oral arguments last week indicated the justices might well overturn at least the individual mandate, if not the whole law.
Still probably won't get him to reconsider retirement.

Actually he has quite a ways to go to get to the nearly $14 million that NC agreed to pay the IRS and isn’t even close to the $33 million that “Douche of the Decade” Joe Francis owed (that has now been dropped we should add) but a $3 million tax lien is nothing to sneeze at.
