Missouri’s state income tax system is structured with progressive tax brackets to ensure equitable taxation based on income levels. For the current tax year, the brackets range from 0% for incomes up to $1,207 to 4.95% for incomes over $8,449. This means that lower-income individuals pay a smaller percentage of their income in taxes, while higher-income earners pay a higher percentage. This progressive structure is designed to distribute the tax burden more fairly among residents, ensuring that those with higher incomes contribute a proportionately larger share to the state’s revenue.
