What the Form MO-1041 Is and when it applies

Form MO-1041 is the Missouri fiduciary income tax return used to report income, deductions, and credits for estates and trusts taxed by the State of Missouri. Executors, administrators, and trustees file this return on behalf of decedents’ estates and certain trusts when Missouri-source income or resident fiduciary status creates a state tax filing obligation. Form MO-1041 parallels federal Form 1041 in structure but reflects Missouri tax law, rates, and credits. It is used to compute tax at the fiduciary level and to report distributable net income passed through to beneficiaries for state tax purposes.
