Mississippi Code
Article 4 - Allocation of Receipts During Administration of Trust
§ 91-17-409. Deferred compensation, annuities, and similar payments

In this section:
To the extent that a payment is characterized as interest, or a dividend, or a payment made in lieu of interest or a dividend, a trustee shall allocate the payment to income. The trustee shall allocate to principal the balance of the payment and any other payment received in the same accounting period that is not characterized as interest, a dividend, or an equivalent payment.
If no part of a payment is characterized as interest, a dividend, or an equivalent payment, and all or part of the payment is required to be made, a trustee shall allocate to income ten percent (10%) of the part that is required to be made during the accounting period and the balance to principal. If no part of a payment is required to be made or the payment received is the entire amount to which the trustee is entitled, the trustee shall allocate the entire payment to principal. For purposes of this subsection, a payment is not "required to be made" to the extent that it is made because the trustee exercises a right of withdrawal.
Except as otherwise provided in subsection (e), subsections (f) and (g) apply, and subsections (b) and (c) do not apply, in determining the allocation of a payment made from a separate fund to:
A trust to which an election to qualify for a marital deduction under Section 2056(b)(7) of the Internal Revenue Code of 1986, as amended, has been made; or
A trust that qualifies for the marital deduction under Section 2056(b)(5) of the Internal Revenue Code of 1986, as amended.
Subsections (d), (f), and (g) do not apply if and to the extent that the series of payments would, without the application of subsection (d), qualify for the marital deduction under Section 2056(b)(7)(C) of the Internal Revenue Code of 1986, as amended.
A trustee shall determine the internal income of each separate fund for the accounting period as if the separate fund were a trust subject to this chapter. Upon request of the surviving spouse, the trustee shall demand that the person administering the separate fund distribute the internal income to the trust. The trustee shall allocate a payment from the separate fund to income to the extent of the internal income of the separate fund and distribute that amount to the surviving spouse. The trustee shall allocate the balance of the payment to principal. Upon request of the surviving spouse, the trustee shall allocate principal to income to the extent the internal income of the separate fund exceeds payments made from the separate fund to the trust during the accounting period.
If a trustee cannot determine the internal income of a separate fund but can determine the value of the separate fund, the internal income of the separate fund is deemed to equal four percent (4%) of the fund's value, according to the most recent statement of value preceding the beginning of the accounting period. If the trustee can determine neither the internal income of the separate fund nor the fund's value, the internal income of the fund is deemed to equal the product of the interest rate and the present value of the expected future payments, as determined under Section 7520 of the Internal Revenue Code of 1986, as amended, for the month preceding the accounting period for which the computation is made.
This section does not apply to a payment to which Section 91-17-410 applies.
