Section 20.7520-2 - Valuation of charitable interests(a)In general -(1)Valuation. Except as otherwise provided in this section and in § 20.7520-3 (relating to exceptions to the use of prescribed tables under certain circumstances), the fair market value of annuities, interests for life or for a term of years, remainders, and reversions for which an estate tax charitable deduction is allowable is the present value of such interests determined under § 20.7520-1 .(2)Prior-month election rule. If any part of the property interest transferred qualifies for an estate tax charitable deduction under section 2055 or 2106, the executor may compute the present value of the transferred interest by use of the section 7520 interest rate for the month during which the interest is transferred or the section 7520 interest rate for either of the 2 months preceding the month during which the interest is transferred. Paragraph (b) of this section explains how a prior-month election is made. The interest rate for the month so elected is the applicable section 7520 interest rate. If the executor elects the alternate valuation date under section 2032 and also elects to use the section 7520 interest rate for either of the 2 months preceding the month in which the interest is transferred, the month so elected (either of the 2 months preceding the month in which the alternate valuation date falls) is the valuation date. If the actuarial factor for either or both of the 2 months preceding the month during which the interest is transferred is based on a mortality experience that is different from the mortality experience at the date of the transfer and if the executor elects to use the section 7520 rate for a prior month with the different mortality experience, the executor must use the actuarial factor derived from the mortality experience in effect during the month of the section 7520 rate elected. All actuarial computations relating to the transfer must be made by applying the interest rate component and the mortality component of the month elected by the executor.(3)Transfers of more than one interest in the same property. If a decedent's estate includes the transfer of more than one interest in the same property, the executor must, for purposes of valuing the transferred interests, use the same interest rate and mortality components for each interest in the property transferred.(4)Information required with tax return. The following information must be attached to the estate tax return (or be filed subsequently as supplemental information to the return) if the estate claims a charitable deduction for the present value of a temporary or remainder interest in property-(i) A complete description of the interest that is transferred, including a copy of the instrument of transfer;(ii) The valuation date of the transfer;(iii) The names and identification numbers of the beneficiaries of the transferred interest;(iv) The names and birthdates of any measuring lives, a description of any relevant terminal illness condition of any measuring life, and (if applicable) an explanation of how any terminal illness condition was taken into account in valuing the interest; and(v) A computation of the deduction showing the applicable section 7520 interest rate that is used to value the transferred interest.(5)Place for filing returns. See section 6091 of the Internal Revenue Code and the regulations thereunder for the place for filing the return or other document required by this section.(b)Election of interest rate component -(1)Time for making election. An executor makes a prior-month election under paragraph (a)(2) of this section by attaching the information described in paragraph (b)(2) of this section to the decedent's estate tax return or by filing a supplemental statement of the election information within 24 months after the later of the date the original estate tax return was filed or the due date for filing the return.(2)Manner of making election. A statement that the prior-month election under section 7520(a) of the Internal Revenue Code is being made and that identifies the elected month must be attached to the estate tax return (or by subsequently filing the statement as supplemental information to the return).(3)Revocability. The prior-month election may be revoked by filing a statement of supplemental information within 24 months after the later of the date the original return of tax for the decedent's estate was filed or the due date for filing the return. The revocation must be filed in the place referred to in paragraph (a)(5) of this section.(c)Effective dates. Paragraph (a) of this section is effective as of May 1, 1989. Paragraph (b) of this section is effective for elections made after June 10, 1994.
