Uncle Sam to Nas Your Music Money Is Ours! #IRSGANGSTA

The next time you buy a Nas album, you're really just handing your money over to the government -- because the rapper's delinquent tax filings have caused Uncle Sam to begin garnishing his wages ... TMZ has learned.

As TMZ first reported, Nas is in tax debt up to his eyeballs ... if you his eyeballs were $6,000,000 tall.

So the government has finally tired of waiting for Nas to pay up, so they filed documents in the state of Georgia to have his wages garnished -- via the music publishing organizations BMI and ASCAP -- until the debt is paid off.

So if you like Nas, but hate the government ... perhaps you'll want to find an alternative way to listen to his music.
