Alabama's tax amnesty program brought in more than $8.1 million. The program, called Operation Clean Slate, ran Feb. 1-May 15.
The state Department of Revenue reports that more than 3,100 individuals and companies used it, and more money came in from businesses than individuals.
Deputy Revenue Commissioner Mike Mason said state officials are pleased with the results.
He said no one knew what to expect because it was the first time the state had waived tax penalties since 1984. That program 25 years ago brought in $3 million.
