Jay-Z
According to Forbes, Jay-Z pulled in $63 million over the past year placing him in the 35% tax bracket, which means a partial of his earnings will go to pay Uncle Sam an estimated $22 million.

"Jay-Z is in a league of his own right now," says Ryan Schinman, chief of Platinum Rye, the country's largest buyer of music and talent for corporations. "There are very few artists of any genre, not just hip-hop, who've created such brands for themselves."
Kanye West’s earnings fell from $25 million last year to $12 million this year in the wake of his highly publicized outburst during Taylor Swift’s acceptance speech at the 2009 Video Music Awards. With a new album and world tour in the offing, he should be back toward the top of next year’s list along with 50 Cent, who took a break from touring and recording to concentrate on film roles over the past year, earning $8 million, a relatively paltry total for the 2008 Cash King.
Drake Hip Hop’s rookie of the year earned $9million thanks to the release of Thank Me Later, partnerships with Sprite and Virgin America. Check the jump for the official list
