The estate process in Missouri

Learn moreShow less

Missouri probate divisions of Circuit Court handle estates. A small-estate affidavit for collection and a refusal of letters are separate procedures. Eligibility, publication, bond, and who is entitled to property need to be checked under the selected route.

Ask whether a small-estate affidavit or refusal of letters applies and whether publication is required.

Missouri's small-estate collection affidavit and refusal of letters are separate probate procedures. The applicant's relationship, debts, value, publication requirements, and any bond questions must be checked for the chosen route. Refusal of letters should not be described as the same thing as unrestricted authority to administer an estate. Where land is involved, ask what certificate or court document establishes the successor's interest before attempting a deed transaction.

State estate and inheritance tax

Learn moreShow less

Missouri does not currently impose a state estate tax for 2026 deaths and does not currently impose a separate inheritance tax for 2026 deaths. This does not mean the inheritance or its future earnings are exempt from federal estate, income, or capital gains tax. Property and a decedent connected to another state can require another state's review. Older deaths can have different rules.

Missouri Revenue describes the federal-credit changes that ended its estate-tax collection for current deaths. The retained estate-tax page is not evidence of a new inheritance tax.
