The executor named in the will (or the court-appointed administrator) is responsible for filing the final income tax return and any estate tax returns. If the deceased was married, the surviving spouse can file a joint federal return for the year of death. For trust assets, the successor trustee handles fiduciary tax returns. The Mississippi executor checklist covers all filing responsibilities in order.
No. Mississippi does not impose a state estate tax or inheritance tax. The primary tax filings after death are income tax related (final return and, if applicable, estate income tax return). See how Mississippi compares with the death tax calculator.
