Payroll errors have cost Hawaii taxpayers $2 million in overpayments to state employees, Hawaii News Now reports.

From the report: “The state said as of Dec. 31, 2011, it overpaid its employees $2 million in outstanding payments, some of them stretching back since 1994.

“The state recovered nearly $470,000 of that, according to a report filed at the end of last year, so there is still more than $1.5 million employees and former employees owe the state.  About 25 percent of the uncollected overpaid wages came from the last two years, with the balance from more than two years ago.”
