People who are behind on their taxes to the State of Missouri may get a break from penalties and interest under a bill being considered in the state.  From the National Association of Enrolled Agents:

On January 27, the Missouri House Ways and Means Committee held a hearing on H. 116, which authorizes an amnesty from the assessment or payment of all penalties, additions to tax, and interest on delinquencies of unpaid taxes administered by the Department of Revenue which occurred on or prior to December 31, 2010. A taxpayer must apply for amnesty, pay the unpaid taxes in full, and agree to comply with state tax laws for the eight years following the date of the agreement. All new revenues resulting from the tax amnesty program will be deposited into the General Revenue Fund, unless otherwise earmarked by the Missouri Constitution. The bill becomes effective July 1, 2011 if signed into law and will expire December 31, 2014.
