(a)        Any interest for which a deduction or exemption is allowed under the federal revenue laws in determining the value of the decedent‘s net taxable estate, such as property passing to or in trust for a surviving spouse and gifts or devises for charitable, public, or similar purposes, shall not be included in the computation provided for in N.C. Gen. Stat. § 28A-27-2 to the extent of the allowable deduction or exemption. When such an interest is subject to a prior present interest which is not allowable as a deduction or exemption, such present interest shall not be included in the computation provided for in this Article and no tax shall be apportioned to or paid from principal.

(b)        Any credit 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 shall inure to the proportionate benefit of all persons liable to apportionment; provided, however, that if the tax which gives rise to such a credit has in fact been paid by a person interested in the estate, the benefit of such credit shall inure to that person paying the tax.

(c)        Any credit for inheritance, succession, or estate taxes or taxes in the nature thereof in respect to property or interests includible in the estate shall inure to the benefit of the persons or interests chargeable with the payment thereof to the extent that, or in the proportion that, the credit reduces the tax.

(d)       To the extent that property passing to or in trust for a surviving spouse or any charitable, public, or similar gift or? devise does not constitute an allowed 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 shall not be included in the computation provided for in this Article, and to that extent no apportionment shall be made against the property. This section does not apply in any instance where the result will be to deprive the estate of a deduction otherwise allowable under Section 2053(d) of the Internal Revenue Code of 1954 of the United States or corresponding provisions of any subsequent tax law, relating to deduction for State death taxes on transfers for public, charitable, or religious uses. ?(1985 (Reg.
