The tax man might be looking for you. And, this time, that’s good news.

Internal Revenue Service said today it is trying to track down the rightful owners of more than 107,000 refund checks worth more than $123.5 million. The U.S. Postal Service returned the checks — including more than 500 mailed to addresses in the St. Louis area — because of mailing address errors.

The refund checks include $952,000 owed to Missourians, and about $3.7 million owed to taxpayers in Illinois. In Missouri, the average unclaimed refund check is $702; in Illinois, it’s $1,023. Some taxpayers are due more than one check.

Michael Devine, an IRS spokesperson in St. Louis, said that the mailing mix-ups often are caused by life changes, like marriage or divorce, that cause an address change.

Devine said taxpayers can avoid undelivered checks by having their refunds deposited directly into checking or savings accounts. Taxpayers who move after filing their tax return can make sure the IRS has their correct address by filing a change of address form available on the IRS website.
