Question 1

What is Missouri's state income tax rate for 2025?

Accepted Answer

Missouri imposes an 8-bracket progressive income tax under Mo. Rev. Stat. §143.011 with rates ranging from 0% (on the first $1,313 of taxable income) up to 4.70% (on income above $9,191), applied uniformly across filing statuses. The top rate declined from 4.80% in TY2024 to 4.70% in TY2025 under the SB 3 (2022) revenue-trigger ratchet mechanism.

Question 2

What is Missouri's standard deduction for 2025?

Accepted Answer

Missouri conforms its standard deduction to the federal amount under Mo. Rev. Stat. §143.121: $14,600 for single and MFS filers, $21,900 for HOH, and $29,200 for married-filing-jointly for TY2025. Missouri does not offer a separate personal exemption, but does allow federal itemized deductions if the taxpayer itemizes federally.

Question 3

Does Missouri tax Social Security and public pension income?

Accepted Answer

Missouri fully exempts Social Security benefits from state income tax for all filers regardless of age or AGI, effective TY2024 under SB 190 (2023), which repealed the prior AGI phase-out at $85,000 single / $100,000 MFJ. Missouri also exempts qualifying public pension income (federal government, Missouri state/local government, and military retirement) via the Public Pension Exemption under Mo. Rev. Stat. §143.124.

Question 4

Do Kansas City and St. Louis charge a local income tax?

Accepted Answer

Yes. Both Kansas City and St. Louis levy a 1% earnings tax on wages earned within their city limits under Mo. Rev. Stat. §92.111 (the STAR Act), applying to both residents and non-residents who work in the city. The tax is collected via employer withholding and filed on Form E-1 (KC) or Form E-1 (St. Louis). Both cities' earnings taxes are re-authorized by voter referendum every five years under §92.115.

What Missouri-specific credits should filers know about for 2025?
