36 M.R.S. § 3984 — Filing of compromise agreement; interest or penalty for nonpayment

When the assessor claims that a decedent was domiciled in this State at the time of the decedent's death and the taxing authorities of another state or states make a like claim on behalf of their state or states, the assessor may, with the approval of the Attorney General, make a written agreement of compromise with the other taxing authorities and the personal representative that a certain sum must be accepted in full satisfaction of any and all death taxes imposed by this State, including any interest or penalties to the date of filing the agreement. The agreement must fix the amount to be accepted by the other states in full satisfaction of death taxes. The personal representative may make that agreement. Either the assessor or the personal representative shall file the agreement or a duplicate with the authority that would be empowered to assess death taxes for this State if there had been no agreement, and upon such filing the tax is deemed conclusively fixed as provided in the agreement. Unless the tax is paid within 30 days after filing the agreement, interest must thereafter accrue upon the amount fixed in the agreement, but the time between the decedent's death and the filing may not be included in computing the interest.
