How net investment income tax applies to trusts
Key takeaway
Certain estates and trusts owe net investment income tax on retained investment income when adjusted gross income exceeds the applicable threshold, while business income treatment depends on the income's character and the applicable participation rules.
Start the review with three questions: Who reports the income? What kind of income is involved? What records support the proposed distribution or business classification?
Keep the trust instrument, income statements, beneficiary payment records and descriptions of trustee responsibilities together for the adviser reviewing those questions.
Research notice: Based on primary sources linked below. Ask an estate attorney or CPA to confirm trust status, income classification, participation evidence and distribution treatment before acting.
Who reports the income?
Ask the preparer to identify any portions with different ownership treatment before reviewing a single total for the trust. See the grantor trust answer below for the ownership rule and related reading.
How distributions affect retained investment income
Undistributed net investment income equals the estate's or trust's net investment income reduced by distributions of net investment income to beneficiaries and the qualifying charitable subtraction described below.
The beneficiary subtraction cannot exceed the lesser of the applicable §651 or §661 deduction and the estate's or trust's net investment income. Mixed distributions require allocation between net investment income and excluded income under the regulatory method.
That allocation treats net investment income as gross income and excluded income as amounts outside gross income. Distributed net investment income retains that character for a recipient subject to §1411.
A cash distribution therefore does not automatically produce an equal reduction in undistributed net investment income. Ask the preparer to show the payment amount, applicable deduction and allocation separately.
Charitable payments require a separate allocation
The charitable subtraction reduces undistributed net investment income only by net investment income allocated to amounts allowable under §642(c).
When both net investment income and excluded income are present, allocation follows the charitable allocation regulation, paragraph (b). Net investment income is treated as gross income, and excluded income as amounts outside gross income.
That allocation rule does not establish eligibility for the underlying charitable deduction. Bring the charitable payment records and the preparer's allocation to the review.
For charitable deduction eligibility and further allocation questions, read the charitable planning guide. For proposed distributions involving gains, see the capital gains answer below.
How investment and business income are classified
Net investment income includes interest, dividends, annuities, royalties and rents, subject to an ordinary course business exception. The business must be neither passive with respect to the taxpayer nor a financial instruments or commodities trading business.
Other gross income from passive or financial trading businesses is included. Taxable net disposition gains are also included, except for gains from property held in a business meeting those same conditions.
Properly allocable deductions reduce the included income and gains. Material participation alone does not exclude financial trading income.
In the regulatory example, an upper tier partnership conducts a business and owns an interest in a lower tier investment partnership that does not conduct a business.
Dividends received through the lower tier partnership are not derived in a trade or business merely because the upper tier partnership conducts one.
Prepare an ownership diagram for layered holdings. See the classification answer below for the levels at which the relevant inquiries are made.
- For interest and dividends, ask which activity generated the receipt.
- For annuities and royalties, request the contracts and income statements used in the review.
- For rents, bring leases and participation records to the rental analysis below.
How one IRS determination treated trustee employment
In a fact specific technical advice determination, the IRS considered §469(h) for purposes of §56(b)(2)(D). The determination did not decide net investment income tax directly and may not be used or cited as precedent.
The IRS looked to fiduciaries' operational work in their fiduciary capacities. A special trustee could control trust property only by selling or voting specified stock.
The memorandum excluded that special trustee's work as a company employee because the work was performed as an employee rather than as a fiduciary.
For a trustee who also works for a business, assemble separate descriptions of employment duties, trustee powers and work actually performed. Ask counsel to evaluate the capacity in which each task was undertaken.
Bring the trust instrument, employment documents and contemporaneous records. Use the primary memorandum in Sources when discussing its factual limits.
How another IRS determination treated sale negotiations
In another fact specific technical advice determination, the IRS rejected special trustee status because the individuals lacked sufficient discretionary authority to act for the trust.
The IRS excluded the trustees' sale negotiation hours on those facts. The remaining operational involvement was insufficiently regular, continuous and substantial.
The memorandum may not be used or cited as precedent. Its treatment of those negotiations does not establish a universal exclusion for every sale related task.
When a sale is involved, organize records by task and responsibility. Include operating work, transaction negotiations, the authority under which each person acted and the supporting time records.
Ask the adviser to compare the particular facts with the memorandum before drawing a conclusion about participation.
What material participation requires
Section 469 applies to estates and trusts. A business activity is generally passive when the taxpayer does not materially participate.
Material participation requires involvement in the activity's operations that is regular, continuous and substantial. Except as regulations provide, an interest held as a limited partner is not treated as an interest in which the taxpayer materially participates.
For the participation review, gather appointment documents, delegated powers, operating records and descriptions of each person's work. Ask counsel to connect the proposed treatment to the taxpayer, the activity and the relevant authority.
For rental activities, review the separate rental rules below before considering the net investment income tax safe harbor.
What the rental safe harbor requires
The net investment income tax rental safe harbor deems qualifying rental receipts and disposition gains or losses to be ordinary course business items.
The taxpayer must be a real estate professional under §469(c)(7)(B). The taxpayer must also participate in the rental activity for more than 500 hours during the tax year.
Alternatively, participation must exceed 500 hours in any five of the immediately preceding ten tax years. Only participation that counts toward §469 material participation counts toward these tests.
The safe harbor uses the rental activity definition in the temporary rental activity regulation, paragraph (e)(3).
An election under the rental real estate regulation, paragraph (g), to treat rental real estate as one activity also applies to the safe harbor.
Rental real estate grouped with a business under the grouping regulation, paragraphs (d)(1)(i)(A) or (d)(1)(i)(C), does not qualify as a rental real estate activity for this safe harbor.
Failure to satisfy the safe harbor does not foreclose another exclusion under §1411. Bring the activity list, participation records and any aggregation election to the adviser.
Keep retirement distributions in a separate category
Distributions from plans or arrangements described in §§401(a), 403(a), 403(b), 408, 408A and 457(b) are excluded from net investment income. That exclusion does not determine whether the distribution is taxable for ordinary income tax purposes.
Provide retirement distribution statements separately from the trust's investment and business income records so the preparer can review each category.
Common questions
Does participation resolve every classification question for a passthrough business?
No, participation does not resolve every income character question for a business held through a passthrough entity. Passive status is determined at the owner level, while financial instruments or commodities trading status is determined at the entity level.
For a business held directly or through a disregarded entity, the ordinary course business inquiry is made at the individual, estate or trust level.
Use the income classification discussion above with the ownership diagram, income statements and activity records.
Does material participation alone make a rental activity nonpassive?
No, rental activities are generally passive regardless of material participation. Section 469(c)(7) provides a rental real estate exception with additional requirements.
The taxpayer must perform more than half of personal business services during the tax year in real property businesses in which the taxpayer materially participates. Services in those businesses must also exceed 750 hours during that year.
Qualifying rental activities remain subject to material participation. Each rental real estate interest is treated separately unless the taxpayer elects aggregation, and limited partner restrictions remain applicable.
Employee services are excluded unless the employee meets the statutory 5 percent owner exception for the employer. On a joint return, either spouse must separately satisfy the service requirements.
Review these requirements with the adviser before considering the separate net investment income tax rental safe harbor.
