Hip-hop producer Swizz Beatz owes the U.S. government more than $2.7m in unpaid taxes.
According to reports the 34-year-old has had tax liens totaling $2.6million filed against him by the federal government in the U.S.
New York has filed a further tax lien for $98,246.18 in unpaid taxes from 2010, reports TMZ.
Beatz, real name Kasseem David Dean, is married to singer Alicia Keys, with whom he has a two-year-old sopn Egypt.
He also has three other children by three women - Prince Nasir, 12, six-year-old Kasseem and four-year-old Nicole.
Grammy winner Beatz has produced for every major name in the record industry, including Beyonce, Chris Brown, Dr Dre and Kanye West.
He has his own record label, Full Surface, which he set up when he was 23.
According to reports last month Alicia is currently close to signing a $12million deal to buy the Englewood estate belonging to actor Eddie Murphy.
The deal is significantly less than the original asking price Murphy originally put the home on the market seven years ago for $30million.
The couple are also selling off their plush New York pad, which is on the market for $17.95million.
Beatz is understood to have bought the home in February 2010, shortly after Keys fell pregnant with Egypt.
