From the Missourian:
Missouri’s Republican-led legislature enacted the state’s first income tax rate reduction in almost a century Tuesday by overriding the veto of Democratic Gov. Jay Nixon, who has denounced it as a reckless financial experiment.
The new law will gradually cut Missouri’s top individual income tax rate starting in 2017 and make the state just the third in the nation to offer a special business-income deduction on personal tax returns. But the incremental tax cuts will occur only if Missouri’s revenues keep growing.
