The IRS says it has half a million dollars it wants to pay to 408 Idahoans, but it can't find them. Here's the report from the Associated Press: NAMPA, Idaho (AP) — The Internal Revenue Service is looking for 408 Idaho taxpayers — and it's actually good news. The Idaho Press-Tribune reports the agency has tax refund checks totaling nearly $500,000 to deliver to those people. The average refund is just over $1,200. Nationwide, nearly 112,000 taxpayers had about $164 million in refunds returned to the IRS as undeliverable. Refund checks are mailed to the address listed on a taxpayer's return. But those checks can be returned as undeliverable if a taxpayer moves without updating his or her address with either the U.S. Postal Service or the IRS. Taxpayers can update their addresses on the "Where's My Refund?" tool on the IRS website. Those without Internet access can call 1-800-829-1954 for instructions on how to update their mailing information.
