Missouri Personal Income Tax Laws

General Overview of Missouri Personal Income Tax Laws

Most states -- including Missouri -- levy a tax on personal incomes, which may also apply to businesses operating within the state. Those states that don't collect income tax often make up for the revenue in other ways, such as higher property taxes. Generally, state income taxes must be filed by mid-April, the same deadline for federal income tax filings. If you are required to file a federal income tax form, you also will have to file a Missouri income tax form, unless:

  • You are a Missouri resident with less than $1,200 in adjusted gross income;
  • You are a non-resident with less than $600 income; or
  • Your adjusted gross income is less than the standard deduction plus your exemption amount.

The basics of Missouri's personal income tax laws are listed in the following table:

Code Section 143.011, et seq.
Who is Required to File Resident individuals, nonresidents with income derived from Missouri sources, and estates and trusts; Partnerships are not taxable; local taxes may be required
Rate First $1,000, 1.5%; Next $1,000, 2%; Next $1,000, 2.5%; Next $1,000, 3%; Next $1,000, 3.5%; Next $1,000, 4%; Next $1,000, 4.5%; Next $1,000, 5%; Next $1,000, 5.5%; Over $9,000, 6%

Note: State laws are always subject to change through the passage of new legislation, rulings in the higher courts (including federal decisions), ballot initiatives, and other means. While we strive to provide the most current information available, please consult an attorney or conduct your own legal research to verify the state law(s) you are researching.

Missouri Income Taxes: What are My Filing Options?

There are three main ways to file your personal income taxes in Missouri, which may depend on your tax obligations and the complexity of your financial situation:

  1. Electronic Filing - Qualified Missouri taxpayers can e-file free of charge, which is the quickest filing method and allows for direct deposits.
  2. 2-D Barcode Filing - The fillable forms (linked) calculate your taxes and provide you with a printed barcode, which can be used by the tax department.
  3. Paper Filing (links to Mo. tax form selector) - The traditional format for calculating and filing taxes.

If you are a nonresident or part-time resident, see the Missouri Dept. of Revenue's Nonresidents and Residents with Other State Income page, which offers detailed instructions and forms.
