Republicans' plan for zero state income tax could be 'devastating', experts warn

AI Summary
Republicans in several US states, including Missouri, are pushing to eliminate state income taxes, which experts warn could have devastating effects on public education and lower- and middle-income residents. The proposal has sparked debate, with proponents arguing it would attract new businesses and put more money in residents' pockets, while critics argue it would only benefit the wealthy.

The Dangers of Eliminating State Income Tax

Hannah Rejali, a mother of four from Missouri, lived through the failed "Kansas Experiment" in the 2010s, when the Republican governor cut the state's income tax, resulting in a $900m budget shortfall and forcing at least eight school districts to end their academic year early.

The Event Details

Missouri is now considering a constitutional amendment to eliminate the state income tax, which would be the first such move in over a century. Advocates argue it would attract new businesses and put extra money in residents' pockets, while critics argue it would hurt lower- and middle-income residents and only help the wealthy.

The Data Analysis

  • Eliminating an income tax could lead to a reduction in state funding for schools, with some experts warning it could be "devastating" for public education.
  • In Kansas, five years after the income tax cuts, the Republican-led legislature voted to roll back most of the tax cuts, overcoming the governor's veto.
  • An Institute on Taxation and Economic Policy analysis found that people making between $49,000 and $80,000 would pay an average of $535 more annually if Missouri increases its sales tax to recoup the revenue lost to its reduction in income taxes.

The Impact Analysis

Experts warn that eliminating state income taxes could have significant impacts on lower- and middle-income residents, who would likely see their taxes increase through other means, such as sales tax expansions. The move could also lead to a decrease in state funding for public services, including education.

The Prediction

If the trend of eliminating state income taxes continues, it could lead to a "frog in boiling water" situation, where the quality of public services gradually degrades over time. Experts argue that the evidence that reducing or eliminating state income taxes attracts new businesses is mixed, and that the benefits of such a move are often overstated.
