Software vendors received the below message from Missouri today. If your site(s) has any MO returns with the mentioned Reject Code, please hold these returns and do not resubmit until we update this post indicating MO has resolved this issue.

Due to an issue identified with our the new MO business rule MO1040-0022, we are in the process of testing a fix to this rejection.  The rule is causing certain returns to reject when a taxpayer has Taxable Social Security but does not meet the requirements for the Social Security Exemption.  We are currently testing a fix on this and hope to have the fix in production next week.  I will update when this is available.
