Our state auditor reported in June:
This tax limitation amendment imposes restrictions on the amount of personal income used to fund state government and the amount by which fees and taxes can be increased. Mathematical formulas are used to determine the relevant threshold amounts each year.
The Hancock Amendment limits the amount of Missourians' personal income that may be used to fund state government to no greater than the portion used to do so in 1981. In other words, since 5.6 percent of Missourians' personal income went to fund state government in 1981, then no more than 5.6 percent can be used to do so in future years, unless revenues are specifically excluded by a vote of the people.
The Hancock Amendment also requires voter approval before taxes or fees can be increased by the General Assembly beyond a certain annual limit. Based upon the calculation provided by the Office of Administration, Division of Budget and Planning, the relevant annual revenue limit for fiscal year 2012 was $84.2 million.For the fiscal year ended June 30, 2013, our review determined no Hancock refunds were due. In fact, total state revenue was approximately $3.6 billion under the refund threshold. In addition, the Office of Administration, Division of Budget and Planning determined that net taxes and fees increased by a total of $28.6 million. As a result, our review concluded the state complied with these provisions of the Hancock Amendment.
The revenue limit has not been exceeded since the year ended June 30, 1999.
