JEFFERSON CITY, Mo. (AP) — The Missouri House has passed legislation that could lower the tax bill for many Missourians by linking the state's tax brackets to inflation. A bill approved on a 146-4 vote would require Missouri's individual income tax brackets to be adjusted annually for inflation starting in 2015. Legislative staff estimate that would reduce state tax revenues by $26 million when fully in effect. Although state tax rates have changed over time, Missouri's top income tax bracket has been set at $9,000 since 1931. That means all income over that amount currently is taxed at the same 6 percent rate. The tax-bracket legislation now goes to the Senate. It's one of several measures lawmakers are considering this year that would reduce state income taxes. ___ Tax bracket bill is HB1268. Online: Legislature: http://www.moga.mo.gov
