Snoop Dogg -- Sippin' On Gin & $546,000 Tax Lien


It's kinda hard bein' Snoop D-O-double-G ... especially when the IRS claims you owe more than $546k in back taxes.

TMZ has learned ... Uncle Sam recently filed a federal lien against Snoop Dogg (Lion) -- real name is Cordozar Broadus -- claiming he owes $546,270.29 in unpaid tax bills.

According to the docs, Snoop owes for two separate years, 2009 ($101,952.44) and 2011 ($444,317.85).  

It ain't Snoop's first brush with the IRS ... he reportedly owed $476k in back taxes back in 2008, but paid up when Uncle Sam brought the debt to Snoop's attention.

We reached out to Snoop's people for comment this time around -- but we're still waiting to hear back.
