THE IRS WANTS ALL OF HIP HOP PRODUCER SEAN GARRETT'S ROYALTIES!

Hip-hop mega-producer has worked with the biggest names in the business, but for the foreseeable future, a portion of every dollar Sean Garrett makes will go straight to the biggest name of all ... UNCLE SAM.

According to docs filed by the Georgia Department of Revenue, Garrett owes back taxes for the years 2006 and 2007 to the tune of $732,553.57.

So the government is tired of waiting for their cash, they ordered BMI, which collects royalties for artists, to hold all money Garrett makes and turn it over to them.

Garrett has produced 15 number one songs in his career -- for the likes of Beyonce, Usher, and Nicki Minaj -- so Uncle Sam should have his money in no time.
