Except as otherwise provided by law, an automatic lien for estate taxes, interest and penalties attaches to all Maine property (real and personal) owned by a decedent at death. The lien does not attach to any property passing by right of survivorship to a surviving joint tenant who was the decedent's spouse on the decedent's date of death. The lien continues until it is released by the State Tax Assessor, except that:
When a personal representative of an estate files a completed Certificate of Discharge of Estate Tax Lien, the Assessor will release the lien upon a showing by the estate that all taxes, interest, and penalties have been paid or a determination by Maine Revenue Services that no tax is due.
