A Missouri Correction Slip is a document issued by the Missouri Department of Revenue to correct errors on a tax return. It is also used to make changes to account information, such as address or bank information. The most common types of Missouri Correction Slip are the 1099-G Correction Slip, the 1099-INT Correction Slip, the 1099-R Correction Slip, and the W-2 Correction Slip. These forms are used to correct errors or update information on the original form sent to the taxpayer. The taxpayer must complete the form, sign it, and mail it to the Missouri Department of Revenue. Once the form is received, the Department will update the taxpayer’s account information and send a corrected form to the taxpayer.
