IRS to Terrell Owens -- Go Looooooong ... & Catch This $430k Tax Bill!

Uncle Sam just gave Terrell Owens 430,000 MORE reasons to find an NFL team STAT -- in the form of a GIANT TAX BILL.

A federal tax lien was filed against the fired wide receiver in February -- claiming T.O. still owes major income tax dollars for the years 2005 ($294,661.71), 2007 ($46,504.00), and 2009 ($97,747.81). All totaled -- he's allegedly in the hole $438,913.52.

As for why the bill's so high -- in those years T.O. was still making big bucks in the NFL playing for the Philadelphia Eagles (under a $49 MIL contract!!!), Dallas Cowboys, and Buffalo Bills.

Fast forward to now ... and he's just got too much time on his hands.
