Miami’s Cash Money rappers are known for making it rain in strip clubs. Now, if only they could make it rain for the government. And founder Bryan Birdman Williams’ condo association, too. Williams was just tagged by the Internal Revenue Service for alleged nonpayment of $1.92million in income taxes for the years 2007 through 2010, according to public records. The taxman liened the $14.5million property that Willams, 45, owns on Palm Island. Until he pays up. Chances are, he will: Forbes estimates he’s worth about $160million through the promotion of giant rap acts like Lil Wayne, Juvenile, Fred Durst, Bow Wow and Young Turk. Lil Wayne, by the way, also has tax problems here. As we reported last year, the IRS slapped a lien on the singer of Lollipop’s La Gorce house because he’s behind his income tax payments. By roughly $12million. Birdman, meanwhile, is having trouble with another money-grabbing entity: the condo association at The Ivy in downtown Miami. If you believe another lien filed against the rap entrepreneur, he hasn’t been paying the maintenance fees for a $330,000 condo he owns there for 15 months. Including late fees, legal fees and other charges, Williams owes $12,447, according to a lawsuit filed by the Ivy. Birdman’s publicist couldn’t be contacted Saturday.
