Knowles, 61, earned a lot of money in those years -- and an IRS report shows that he owes more than $1 million in back taxes, according to TMZ.
The lien filed against Knowles reports that he owes $485,575.95 from 2010 and $728,004.89 from 2011. In that time, he managed both Beyonce's career and his own record label, among other projects.
