Chris Tucker doesn't work a lot these days.

He may have to start doing stoner comedies again because he owes the IRS a ton of money.

Tucker has a long history of tax struggles and the bill for his latest round is $9,684,452.

That's $4,614,070 for 2002; $2,182,803 for 2006; $2,406,024 for 2008; and $481,552 for 2010.

The Friday star and the IRS had reached an agreement in 2014 after Uncle Sam filed a $2.5 million lien on his home.   But Tucker didn't honor it, and the government doesn't forget.

“Despite notice and demand for payment of the assessments set forth above, Mr. Tucker has neglected, refused, or failed to fully pay the assessments against him,” the IRS latest suit against the actor says.
