If you and your wife are Missouri residents, then report all your income to Missouri. If you paid taxes to Kansas on your income, Missouri will give you credit for the tax you paid Kansas.
If you paid Kansas taxes on your income, you would file a Non-Resident return to Kansas and report only your Kansas income. Prepare your Kansas non-resident return first, then your Missouri resident return.
