Nuclear decommissioning funds use Form 1120ND, Return for Nuclear Decommissioning Funds and Certain Related Persons, to report contributions received, income earned, the administrative expenses of operating the fund, and the tax on modified gross income. The return is also used to report the section 4951 initial taxes on self-dealing.
All section 468A nuclear decommissioning funds must file Form 1120-ND. A disqualified person engaging in self-dealing must file Form 1120-ND to report the initial tax. See Part II, Initial Taxes on Self-Dealing (Section 4951), to determine if an individual has engaged in self-dealing as a trustee or disqualified person.
Generally, a fund must file its income tax return by the 15th day of the 3rd month after the end of its tax year. The return of a trustee or self-dealer who owes tax under section 4951 must be filed by the 15th day of the 3rd month after the end of the tax year of the trustee or self-dealer.
