This mailing is in response to taxpayers’ failure to respond to or resolve 30,584 Notices of Proposed Income Tax Adjustments mailed on July 9. The current mailing means almost 80 percent of taxpayers receiving the initial notice did not respond.
Treasury's mailings were for taxpayers whose federal income tax increased as a result of the federal CP2000 document-matching program and failed to prepare an amended Michigan income tax return to pay the additional Michigan income tax.
While some were not required to amend their Michigan return because the federal tax increase was less than $500, they were still required to pay the additional tax shown on the July 9 notice.
