HB 397 -- Income Tax: Non-Missouri Source Income Co-Sponsors: Roark, Cooper (120), Crowell This bill allows a resident taxpayer who was domiciled in another state for at least 30 consecutive days and had income from that state to exclude that income from the computation of Missouri individual income tax. Under current law, the resident taxpayer must include the non-Missouri source income in the computation of Missouri individual income tax and take a credit against Missouri taxes for the amount of taxes paid to the other state.Copyright (c) Missouri House of Representatives
