IRS Instruction 1120-ND – In the complex world of tax compliance for specialized entities, IRS Form 1120-ND stands out as a critical filing for nuclear decommissioning funds. This form ensures that funds set aside for the safe decommissioning of nuclear power plants report their financial activities accurately. Whether you’re managing a nuclear decommissioning fund or dealing with related tax obligations, understanding the instructions for Form 1120-ND is essential to avoid penalties and maintain compliance. This SEO-optimized guide breaks down everything you need to know, drawing from official IRS sources for the most current information as of 2025.
What is IRS Form 1120-ND?
IRS Form 1120-ND, titled “Return for Nuclear Decommissioning Funds and Certain Related Persons,” is specifically designed for nuclear decommissioning funds under section 468A of the Internal Revenue Code. These funds are established to cover the costs of decommissioning nuclear power plants, ensuring environmental safety and regulatory adherence. The form allows these entities to report key financial elements, including contributions received from utilities or other sources, income earned through investments, administrative expenses incurred in operating the fund, and the tax on modified gross income. Additionally, it covers section 4951 initial taxes on self-dealing, which apply to certain prohibited transactions.
Unlike general corporate tax returns like Form 1120, Form 1120-ND is tailored to the unique tax treatment of these trusts, which are taxed at a flat rate on their modified gross income. This specialized return helps the IRS monitor the funds’ activities to ensure they remain dedicated to their intended purpose without undue tax advantages.
Who Must File Form 1120-ND?
Not every entity files Form 1120-ND—it’s reserved for specific parties involved in nuclear decommissioning. All nuclear decommissioning funds qualified under section 468A must submit this form annually. These are typically trusts created by public utilities or nuclear plant operators to accumulate resources for future decommissioning costs.
Additionally, certain related persons, such as disqualified individuals or entities engaging in self-dealing transactions, are required to file Form 1120-ND to report and pay initial taxes under section 4951. Self-dealing might include improper use of fund assets for personal benefit, triggering these reporting obligations. If you’re unsure whether your fund or role qualifies, consult the IRS guidelines or a tax professional to determine filing requirements.
When is the Due Date for Filing Form 1120-ND?
The due date for Form 1120-ND aligns with standard corporate tax deadlines. Generally, the return must be filed by the 15th day of the fourth month following the end of the fund’s tax year. For calendar-year filers (ending December 31), this means April 15 of the following year. If the due date falls on a weekend, holiday, or non-business day, it shifts to the next business day.
Extensions are available by filing Form 7004, which provides an automatic six-month extension for the return—but remember, this extends only the filing deadline, not the payment of any taxes owed. Electronic filing is encouraged for accuracy and speed, and the IRS accepts e-filed returns for most business forms, including variants like 1120-ND.
How to File Form 1120-ND: Step-by-Step Instructions?
Filing Form 1120-ND requires careful attention to the IRS instructions, which are revised periodically. The December 2025 revision applies to tax year 2025 and beyond until updated. Here’s a high-level overview based on official guidance:
- Gather Required Information: Collect details on contributions, investment income, expenses, and any self-dealing activities. You’ll need an Employer Identification Number (EIN) if not already obtained via Form SS-4.

- Identifying Information: Enter the fund’s name, address, EIN, and tax year.
- Income Section: Report contributions, interest, dividends, capital gains, and other income sources to calculate modified gross income.

- Schedules and Attachments: Include Schedule A for self-dealing taxes if applicable, and attach any required forms like Form 8949 for capital asset dispositions.

Penalties for Late Filing or Non-Compliance
Failing to file Form 1120-ND on time can result in significant penalties. The IRS imposes a late filing penalty of 5% of the unpaid tax for each month or partial month the return is overdue, up to a maximum of 25%. If the return is more than 60 days late, a minimum penalty applies, which is the lesser of $510 or 100% of the tax due (adjusted for inflation).
Additional penalties may apply for failure to pay taxes owed, underpayment of estimated taxes, or fraud. To avoid these, file extensions if needed and make timely payments. The IRS also charges interest on unpaid amounts from the due date until payment is made.
Recent Changes and Updates for 2025
The IRS periodically updates Form 1120-ND instructions to reflect legislative changes. For the December 2025 revision, key notes include using this version for 2025 tax years and beyond until superseded. There are mentions of increases in certain areas, potentially related to penalty thresholds or deduction limits, but no major overhauls specific to nuclear funds were highlighted in recent IRS publications.
Broader corporate tax changes, such as expansions in section 168(k) bonus depreciation for qualified property (including certain sound recording productions, though not directly applicable here), may indirectly affect fund investments. Always check the IRS website for the latest developments, as legislation like P.L. 119-21 could impact deductions starting in mid-2025.
