Is this considered double dipping?

I'm thinking so:

At a time when the White House is projecting the largest deficit in the nation's history, Uncle Sam is trying to recover billions of dollars in unpaid taxes from its own employees.

Federal workers owe more than $3 billion in income taxes they failed to pay in 2008. According to Internal Revenue Service documents, 276,300 federal employees and retirees owe $3,042,200,000.

The IRS tracks the voluntary compliance rate of federal employees and retirees each year, and each year feds come up short.

Interestingly enough, the report suggests that things are actually getting better, with federal employees owing less this past year than earlier years.

Sadly, a good chunk of the debt is from military retirees:

Retired military personnel make up about 33 percent of the money owed with $1,343,538,055 in unpaid taxes for 2008.

What the hell is up with that?  Can't help but think there's more to this story.

Try a cabinet appointment — that seems to get ‘em to pay up.
