SB 1180 - This act defines the term "maximum social security benefit available" as thirty-two thousand five hundred dollars for the tax year beginning on or after January 1, 2007. Such amount will increase annually by the percentage increase in the consumer price index. Currently, a taxpayer must be age sixty-two years or older in order to be eligible for the income tax exemption for publicly funded retirement benefits. This act removes the age requirement for the publicly funded retirement benefit income tax exemption. Under current law, taxpayers who receive both social security benefits and publicly funded retirement benefits recipient must reduce the amount of their publicly funded retirement benefit exemption by the total amount of social security benefits not included in Missouri adjusted gross income. This act would require such taxpayers to reduce their publicly funded retirement benefit exemption by the amount of social security benefits exempted due to the enactment of House Bill 444 (2007).
