JEFFERSON CITY, Mo. (AP) — Missouri Gov. Jay Nixon has signed legislation that will grant amnesty to some delinquent taxpayers.The bill signed by Nixon on Monday will waive interest, fees and other penalties for those who pay back taxes this fall.The period to pay back taxes without penalties runs from Sept. 1 through Nov. 30. Missourians under civil or criminal investigation for tax-related reasons are not eligible.Those who take advantage of the amnesty period must follow state tax laws for eight years.Legislative researchers estimate the measure will bring in more than $60 million for the state next fiscal year. Most of that will be set aside to pay for adult dental coverage for Medicaid recipients, as well as provider rate reimbursements.
