How Missouri Income Tax Works
Missouri uses a progressive tax system with 7 brackets ranging from 2.0%. Higher earners pay a higher percentage on the portion of income above each threshold. The state calculates your tax by applying each bracket's rate to the corresponding slice of your taxable income, then sums the result.
When you earn income in Missouri, your employer withholds both federal income tax (sent to the IRS) and MO state tax (sent to the Missouri Department of Revenue). At tax time, you file two separate returns: one federal (Form 1040) and one MO state return.
You can file Missouri state taxes through tax software (TurboTax, H&R Block, FreeTaxUSA), hire a local accountant, or file directly with the Missouri Department of Revenue. Most MO state returns are due April 15, the same as federal. Some states offer a 6-month extension (to October 15) if you also extend your federal return.

- FICA (Social Security + Medicare): $5,738 (7.65% on first $168,600)
- Total annual tax burden: ~$19,098
