Terrell Owens -- KO's $430,000 Tax Bill

Terrell Owens can't find a football team ... or do the weather ... but he CAN open his wallet -- the former NFL'er just paid off a tax debt to the tune of $430,000.

TMZ broke the story ... Uncle Sam filed a federal tax lien against T.O. back in February for the years 2005 ($294,661.71), 2007 ($46,504.00), and 2009 ($97,747.81). Total debt -- $438,913.52.

A man of honor ... T.O. kicked the crap out of the lien and paid it all off ... every last cent. It was officially released on June 27th.

Now T.O. can get back to trying out new careers -- like his failed attempt at weatherman.
