Your Missouri State AGI is the first major stage of the 2026 example. It is your adjusted income after applying state-level rules.

Missouri State Adjusted Income 2026
DescriptionAmount
Federal Adjusted Gross Income (AGI)$ 300,000.00
-Personal Exemption Deduction$ 15,750.00
=State Adjusted Income$ 284,250.00
Note:
1. State AGI begins with Federal AGI unless the state applies additional adjustments.
2. Exemption deductions apply only in states that use deduction-based systems; states using exemption credits do not reduce AGI at this stage.
3. Dependent counts are drawn from the entries in the Profile settings tab, where the number of qualifying children and other dependents is defined.
4. These dependent values affect State AGI only when the state uses deduction-based exemptions. States using credits apply dependent amounts later in the credit calculation section.
5. Adjusting dependent information in the Profile tab updates this calculation automatically.

Once established, this number leads directly into the deduction step. This is where Missouri applies your 2026 deduction, removing part of your income before tax brackets are applied.
