(a) Unless the will provides otherwise, the tax shall be apportioned among all persons interested in the estate. The apportionment is to be made in the proportion that the value of the interest of each person interested in the estate bears to the total value of the interests of all persons interested in the estate. The values used in determining the tax are to be used for that purpose. If the decedent's will directs a method of apportionment of tax different from the method described in AS 13.06 - AS 13.36, the method described in the will controls.
(b) The court in which venue lies for the administration of the estate of a decedent, on petition for the purpose, may determine the apportionment of the tax.
(c) If the court finds that it is inequitable to apportion interest and penalties in the manner provided in (a) of this section, because of special circumstances, it may direct apportionment of them in the manner it finds equitable.
(d) If the court finds that the assessment of penalties and interest assessed in relation to the tax is due to delay caused by the negligence of the fiduciary, the court may charge the fiduciary with the amount of the assessed penalties and interest.
(e) In any action to recover from any person interested in the estate the amount of the tax apportioned to the person in accordance with AS 13.06 - AS 13.36, the determination of the court in respect thereto shall be prima facie correct.
(f) The personal representative or other person in possession of the property of the decedent required to pay the tax may withhold from any property distributable to any person interested in the estate, upon its distribution, the amount of tax attributable to the distributee's interest. If the property in possession of the personal representative or other person required to pay the tax and distributable to any person interested in the estate is insufficient to satisfy the proportionate amount of the tax determined to be due from the person, the personal representative or other person required to pay the tax may recover the deficiency from the person interested in the estate. If the property is not in the possession of the personal representative or the other person required to pay the tax, the personal representative or the other person required to pay the tax may recover from any person interested in the estate the amount of the tax apportioned to the person in accordance with this chapter.
(g) If property held by the personal representative is distributed before final apportionment of the tax, the distributee shall provide a bond or other security for the apportionment liability in the form and amount prescribed by the personal representative.
(h) In making an apportionment, allowances shall be made for any exemptions granted, for any classification made of persons interested in the estate, and for any deductions and credits allowed by the law imposing the tax.
(i) Any exemption or deduction allowed by reason of the relationship of any person to the decedent or by reason of the purposes of the gift inures to the benefit of the person bearing the relationship or receiving the gift; but if an interest is subject to a prior present interest that is not allowable as a deduction, the tax apportionable against the present interest shall be paid from principal.
(j) Any deduction for property previously taxed and any credit for gift taxes or death taxes of a foreign country paid by the decedent or the decedent's estate inures to the proportionate benefit of all persons liable to apportionment.
(k) Any credit for inheritance, succession, or estate taxes, or taxes in the nature thereof applicable to property or interests includable in the estate, inures to the benefit of the persons or interests chargeable with the payment thereof to the extent proportionately that the credit reduces the tax.
(l) To the extent that property passing to or in trust for a surviving spouse or any charitable, public, or similar gift or devisee is not an allowable deduction for purposes of the tax solely by reason of an inheritance tax or other death tax imposed upon and deductible from the property, the property is not included in the computation provided for in (a) of this section, and to that extent no apportionment is made against the property. This subsection does not apply to any case if the result would be to deprive the estate of a deduction otherwise allowable under Section 2053(d) of the Internal Revenue Code of 1954, as amended, of the United States, relating to deduction for state death taxes on transfers for public, charitable, or religious uses.
(m) No interest in income and no estate for years or for life or other temporary interest in any property or fund is subject to apportionment as between the temporary interest and the remainder. The tax on the temporary interest and the tax, if any, on the remainder is chargeable against the corpus of the property or funds subject to the temporary interest and remainder.
(n) Neither the personal representative nor other person required to pay the tax is under any duty to institute any action to recover from any person interested in the estate the amount of the tax apportioned to the person until the expiration of the three months next following final determination of the tax. A personal representative or other person required to pay the tax who institutes the action within a reasonable time after the three-month period is not subject to any liability or surcharge because any portion of the tax apportioned to any person interested in the estate was collectable at a time following the death of the decedent but thereafter became uncollectable. If the personal representative or other person required to pay the tax cannot collect from any person interested in the estate the amount of the tax apportioned to the person, the amount not recoverable shall be equitably apportioned among the other persons interested in the estate who are subject to apportionment.
(o) A personal representative acting in another state or a person required to pay the tax domiciled in another state may institute an action in the courts of this state and may recover a proportionate amount of the federal estate tax, of an estate tax payable to another state or of a death duty due by a decedent's estate to another state, from a person interested in the estate who is either domiciled in this state or who owns property in this state subject to attachment or execution. For the purposes of the action the determination of apportionment by the court having jurisdiction of the administration of the decedent's estate in the other state is prima facie correct.
