Being a Kansas resident, when I report my Missouri income as a non-resident, am I required to report the investment income and business income as Missouri source income?

[BillM223]

Generally, if you are a resident of one state and work in another, you allocate only the income which you earned working in that nonresident state to the nonresident state.. The investment income would not normally be reported in the nonresident state, unless that income had some connection (nexus) with that state. Ditto with the business - you would report only business income and expenses that are Missouri-sourced (this is on a screen in the Missouri interview labeled "Missouri Business Income Deduction").

What is the source of your Missouri income? W-2? Self-employment?
