St. Louis rapper Nelly has run afoul uncle Sam, and has been hit with a massive tax bill.

According to reports, Nelly owes the federal government $2,412,283 in back taxes.

His state taxes aren’t so bad, but they clock in at $149,511, including penalties and interest.

The state has already filed a lawsuit against Natalie to collect the back taxes.

The feds could start seizing his property, assets and bank accounts, if he doesn’t start paying, or reach a settlement.

Nelly is reportedly working with his accountants to sort out the tax bill.
