Topeka ? The Internal Revenue Service says 690 Kansans are still due a tax refund.

Michael Devine, spokesman for the IRS in Kansas and Missouri, says the Kansans missing refunds are among 112,000 Americans nationwide who have not received their refunds. The national total of unpaid refunds is $164.6 million.

Devine tells The Topeka Capital-Journal that 681 of the refunds checks were returned in Kansas because of mailing address errors, for total of $169,000. He says such life changing events as marriage or divorce can cause address changes.
