Trouble continues to chase Floyd Mayweather Jr. The Internal Revenue Service is once again going after the unbeaten boxer for an unpaid sum of money. This time the IRS hit Mayweather with a near $3.4 million dollar tax bill. The amount is related to his earnings from 2009, when he came out of retirement to win a decision over Juan Manuel Marquez, and earned a reported $25 million. The IRS filed a lien for $3,359,279 against Mayweather with the Clark County (Las Vegas, Nevada) Recorder.

Not the first tax bill for Mayweather. A few years ago the IRS chased him down with a lien for $6,165,735. The fighter would later negotiate a payment plan.
