Edward Sobczewski, 47, is accused of asking the agent to change his 2006 personal tax audit in exchange for Colorado Rockies season tickets.
If convicted, Sobczewski faces up to 15 years in prison, and up to a $250,000 fine for each of four counts.
Said U.S. Attorney Troy Eid: "The message is simple: Don't even think about bribing an IRS agent with Rockies' tickets or anything else."
And especially not the way this season is going. He's lucky they don't nail him for felony menacing.
