Missouri State-Specific Tax Details (2026)
Pass-Through Entity (PTE) Tax Election
Missouri allows S corporations and partnerships (including LLCs taxed as such) to elect entity-level tax via Form MO-PTE. The PTE rate equals the highest individual income tax rate, which is 4.7% for tax year 2026. The election is annual and irrevocable for the year elected. Owners claim an offsetting Missouri credit (Form MO-TC, or document their share via Form MO-5889) to avoid double taxation while restoring the federal deduction above the SALT cap. Under HB 1912 (signed July 12, 2024; effective Aug 28, 2024), any member may file an opt-out to exclude their allocable share. Note: the DOR entity-tax FAQ currently publishes rates only through TY2024 (4.8%); the 2026 rate is derived from the top-individual-rate rule. Confirm current-year mechanics with a Missouri tax professional.
Local & City Income Taxes
Kansas City and St. Louis each levy a 1% earnings tax on wages and net business profits earned in the city (residents taxed on all earnings; non-residents on city-source earnings only). Both were reauthorized by voters on April 7, 2026, for another 5 years (through 2031). No other Missouri city or county imposes a local income tax.
Entity-Level & Franchise Taxes
Missouri repealed its corporate franchise tax for tax years beginning on/after Jan 1, 2016 — there is no franchise, gross-receipts, or margin tax. Entities still file an annual report with the Secretary of State. The corporate income tax is a flat 4.0% (among the lowest in the nation). S corporations are recognized as pass-throughs and pay no Missouri corporate income tax; income flows to shareholders. S corporations and partnerships may instead elect the PTE tax at the 4.7% top individual rate.
Missouri Tax Credits & Incentives
Missouri's primary expansion/retention incentive. Qualifying businesses creating new full-time jobs may retain the state withholding tax on those jobs and/or receive a refundable, sellable, and transferable corporate income tax credit equal to a percentage of new payroll, typically for up to 5 years (existing Missouri companies may qualify for an additional year). Administered by the Department of Economic Development.
A 15% income tax credit on additional qualifying research expenses (20% if the research is conducted with a Missouri public or private college/university), capped at $300,000 per taxpayer per year under a $10M annual program cap, of which $5M is reserved for small businesses and minority/women-owned enterprises. Available for tax years 2023 through 2028; annual application window Jan 1-Sep 30.
Missouri certifies employers (it does not fund the credit) for the FEDERAL WOTC, worth up to $9,600 per qualified hire from targeted groups (e.g., certain veterans, long-term unemployed). IMPORTANT 2026 caveat: federal WOTC authorization covered employees who begin work on or before Dec 31, 2025; absent congressional reauthorization it generally cannot be claimed for 2026 start dates. Verify current federal status before relying on it.
Per the current DOR FAQ, Missouri's 100% individual capital gains subtraction applies to tax years beginning on or after January 1, 2026 (first claimed on the 2026 return filed in 2027). A pass-through owner planning a 2026 sale of business assets, stock, or real estate can structure the gain to flow to their individual Missouri return (Form MO-A) to potentially eliminate Missouri tax on that gain. Caution: the 100% CORPORATE-level subtraction is NOT yet in effect — it triggers only for the tax year after the top individual rate falls to 4.5% or lower (currently 4.7%), so C corps and the corporate portion of a sale get no benefit in 2026. Some non-DOR sources cite a 2025 effective date for the individual subtraction; rely on the DOR FAQ and confirm with a Missouri tax professional.
Top Tax Strategies for Missouri Business Owners
Missouri offers a moderate tax environment. While state taxes are manageable, combining federal and state strategies can still save you thousands each year.
S-Corp salary optimization
Missouri Works Program
Retirement plan maximization
S-Corp Election in Missouri
For Missouri business owners with net income above $50,000, electing S-Corp status can save $5,000 to $20,000+ annually in self-employment taxes. As an S-Corp, you pay yourself a "reasonable salary" and take the remaining profits as distributions, which are not subject to the 15.3% self-employment tax. Keep in mind that Missouri's 2% - 4.8% income tax still applies to both your salary and your distributions, so the S-Corp election saves you federal self-employment tax while your state planning shifts to deductions, retirement contributions.
Example: A Kansas City S-Corp
A Kansas City business owner earning $150,000 in net business income pays themselves a reasonable salary of $60,000. The remaining $90,000 in distributions avoids the 15.3% SE tax, saving $13,770 in self-employment taxes alone — on top of whatever your Missouri state planning adds.
Retirement Plan Strategies for Missouri
Retirement plan contributions are the single most powerful tax deduction available to Missouri business owners. A Solo 401(k) allows contributions up to $69,000 in 2026 ($76,500 if you're 50+), generating tax savings of $17,000 to $24,000 at a 25-32% effective tax rate. For Missouri owners, those contributions cut both your federal bill and your 2% - 4.8% state income tax, stacking the savings.
SALT Deduction Impact in Missouri
Moderate and declining SALT impact. The federal SALT (State and Local Tax) deduction cap increases from $10,000 to $40,000 in 2026, providing meaningful relief for business owners in states with income taxes.
