Summary

An electing Settlement Trust and its beneficiaries follow special federal tax rules when the trust’s trustee makes the one-time election. The trust pays tax on its taxable income (other than net capital gain) at the lowest rate shown in section 1(c). If the trust has a net capital gain, that gain is taxed at the rate that would apply if the trust’s other income were taxed only at the lowest rate in section 1(c). These taxes replace the usual income tax on that income. The trustee must make the election by the due date (including extensions) for the trust’s tax return for the first taxable year ending after the law was passed and must attach a statement to that return. Once made, the election covers that year and all later years and generally can’t be revoked, except under special transfer rules. Contributions to an electing trust are not taxed to beneficiaries, and the sponsoring Native Corporation’s earnings aren’t reduced because of those contributions. When the trust pays out money to beneficiaries, the payments are treated in a four-step order: first, as amounts excluded up to the trust’s taxable income (minus tax the trust paid) and certain tax-exempt items; second, as excluded to the extent of unused prior-year exclusions while the election was in effect; third, as distributions tied to the sponsoring Native Corporation’s earnings and profits; and fourth, as amounts over the trust’s distributable net income. If the trust’s interests or the sponsoring corporation’s stock can later be transferred in ways not allowed by section 7(h) of the Alaska Native Claims Settlement Act, no election can be made and any existing election ends at the start of the year transfers are first allowed, with special rules increasing the trust’s distributable income by the corporation’s earnings (but not above the trust’s fair market value). The trust’s taxable income is figured under section 641(b) without certain deductions. Key terms: electing Settlement Trust (a trust that made the election), Native Corporation, Settlement Common Stock, Settlement Trust, and sponsoring Native Corporation. Any shareholder loss on sponsoring corporation stock is reduced by a per-share adjustment equal to aggregate contributions to that corporation’s electing trusts expressed per share. For reporting rules see section 6039H.

There is hereby imposed on the taxable income of an electing Settlement Trust, other than its net capital gain, a tax at the lowest rate specified in section 1(c).
(2)Capital gain
In the case of an electing Settlement Trust with a net capital gain for the taxable year, a tax is hereby imposed on such gain at the rate of tax which would apply to such gain if the taxpayer were subject to a tax on its other taxable income at only the lowest rate specified in section 1(c).
Any such tax shall be in lieu of the income tax otherwise imposed by this chapter on such income or gain.
(c)One-time election
(1)In general
A Settlement Trust may elect to have the provisions of this section apply to the trust and its beneficiaries.
(2)Time and method of election
An election under paragraph (1) shall be made by the trustee of such trust—
(A)on or before the due date (including extensions) for filing the Settlement Trust’s return of tax for the first taxable year of such trust ending after the date of the enactment of this section, and
(B)by attaching to such return of tax a statement specifically providing for such election.
(3)Period election in effect
Except as provided in subsection (f), an election under this subsection— (A)
(B)may not be revoked once it is made.
(d)Contributions to trust
(1)Beneficiaries of electing trust not taxed on contributions
In the case of an electing Settlement Trust, no amount shall be includible in the gross income of a beneficiary of such trust by reason of a contribution to such trust.
(2)Earnings and profits
The earnings and profits of the sponsoring Native Corporation shall not be reduced on account of any contribution to such Settlement Trust.
(e)Tax treatment of distributions to beneficiaries
Amounts distributed by an electing Settlement Trust during any taxable year shall be considered as having the following characteristics in the hands of the recipient beneficiary:
(1)First, as amounts excludable from gross income for the taxable year to the extent of the taxable income of such trust for such taxable year (decreased by any income tax paid by the trust with respect to the income) plus any amount excluded from gross income of the trust under section 103.
(2)Second, as amounts excludable from gross income to the extent of the amount described in paragraph (1) for all taxable years for which an election is in effect under subsection (c) with respect to the trust, and not previously taken into account under paragraph (1).
(3)Third, as amounts distributed by the sponsoring Native Corporation with respect to its stock (within the meaning of section 301(a)) during such taxable year and taxable to the recipient beneficiary as amounts described in section 301(c)(1), to the extent of current or accumulated earnings and profits of the sponsoring Native Corporation as of the close of such taxable year after proper adjustment is made for all distributions made by the sponsoring Native Corporation during such taxable year.
(4)Fourth, as amounts distributed by the trust in excess of the distributable net income of such trust for such taxable year.
Amounts distributed to which paragraph (3) applies shall not be treated as a corporate distribution subject to section 311(b), and for purposes of determining the amount of a distribution for purposes of paragraph (3) and the basis to the recipients, section 643(e) and not section 301(b) or (d) shall apply.
(f)Special rules where transfer restrictions modified
(1)Transfer of beneficial interests
If, at any time, a beneficial interest in an electing Settlement Trust may be disposed of to a person in a manner which would not be permitted by section 7(h) of the Alaska Native Claims Settlement Act (43 U.S.C. 1606(h)) if such interest were Settlement Common Stock—
(A)no election may be made under subsection (c) with respect to such trust, and
(B)if such an election is in effect as of such time—
(i)such election shall cease to apply as of the first day of the taxable year in which such disposition is first permitted,
(ii)the provisions of this section shall not apply to such trust for such taxable year and all taxable years thereafter, and
(iii)the distributable net income of such trust shall be increased by the current or accumulated earnings and profits of the sponsoring Native Corporation as of the close of such taxable year after proper adjustment is made for all distributions made by the sponsoring Native Corporation during such taxable year.
In no event shall the increase under clause (iii) exceed the fair market value of the trust’s assets as of the date the beneficial interest of the trust first becomes so disposable. The earnings and profits of the sponsoring Native Corporation shall be adjusted as of the last day of such taxable year by the amount of earnings and profits so included in the distributable net income of the trust.
(2)Stock in corporation
If—
(A)stock in the sponsoring Native Corporation may be disposed of to a person in a manner which would not be permitted by section 7(h) of the Alaska Native Claims Settlement Act (43 U.S.C. 1606(h)) if such stock were Settlement Common Stock, and
(B)at any time after such disposition of stock is first permitted, such corporation transfers assets to a Settlement Trust,
paragraph (1)(B) shall be applied to such trust on and after the date of the transfer in the same manner as if the trust permitted dispositions of beneficial interests in the trust in a manner not permitted by such section 7(h).

For purposes of this section, the surrender of an interest in a Native Corporation or an electing Settlement Trust in order to accomplish the whole or partial redemption of the interest of a shareholder or beneficiary in such corporation or trust, or to accomplish the whole or partial liquidation of such corporation or trust, shall be deemed to be a transfer permitted by section 7(h) of the Alaska Native Claims Settlement Act.
