(1) When the executive director of the department of revenue claims that a decedent was domiciled in this state at the time of his death and the taxing authorities of another state make a like claim on behalf of their state, the said executive director may make a written agreement of compromise with the other taxing authorities and the executor or administrator of such decedent that a certain sum shall be accepted in full satisfaction of all inheritance taxes imposed by this state, including any interest or penalties to the date of signing the agreement. The agreement shall also fix the amount to be accepted by the other states in full satisfaction of inheritance taxes. The executor or administrator of such decedent is authorized to make such agreement. Such agreement shall finally and conclusively fix and determine the amount of tax payable to this state without regard to any other provision of the laws of this state.
