The Internal Revenue Service is looking for 3,198 New Jersey taxpayers who can claim their share of undelivered refund checks totaling $6.97 million. These undelivered refund checks were returned to the IRS by the U.S. Postal Service due to mailing address errors. The IRS can reissue the checks, which average $2,181 after taxpayers correct or update their addresses with the IRS. Nationally, there are 111,893 taxpayers with undelivered refunds, totaling $164.6 million with an average refund of $1,471. “If you think you are missing a refund, the sooner you update your address information, the quicker you can get your money,” said Gregg Semanick, IRS New Jersey Spokesperson. “A taxpayer only needs to update his or her address once for the IRS to send out all checks due.” If a refund check is returned to the IRS as undelivered, taxpayers can generally update their addresses with the “Where’s My Refund?” tool on www.irs.gov.
