Simple vs. Complex Trusts, Grantor Trust Rules

12.1 Simple vs. Complex Trusts, Grantor Trust Rules

Trusts play a central role in estate planning and wealth management, and they appear frequently in the context of the Tax Compliance and Planning (TCP) CPA exam. Understanding how income passes through different types of trusts, respecting distribution requirements, and analyzing reversionary powers that trigger grantor trust status is crucial for aspiring CPAs. This section examines the distinctions between simple and complex trusts, outlines tax-related distribution rules, and delves into the standards that classify a trust as a grantor trust under the Internal Revenue Code (IRC). We will also explore practical examples, provide illustrative diagrams, and offer real-world scenarios to solidify these concepts.

Overview of Trust Classification for Tax Purposes

At the federal tax level, trusts are generally governed by Subchapter J of the IRC. The two primary trust classifications for income tax purposes are: • Simple Trusts.
• Complex Trusts.

Additionally, certain trusts that retain specific powers or benefits for the person creating the trust (the “grantor”) may be treated as grantor trusts under IRC §§ 671–678. Recognizing how each classification affects income taxation, deductions, and reporting obligations helps CPAs provide sound tax compliance and planning advice.

Simple Trusts

A “simple trust” is generally defined under the IRC and corresponding Treasury Regulations as one that:

1. Must distribute all of its income (as defined in the trust agreement and local law) currently to the beneficiaries.
2. Does not distribute any principal or make charitable contributions during the taxable year.
3. Does not specify any other amount that must be distributed apart from the income.

In simple trusts, the trust itself typically receives a deduction for the distributable net income (DNI) that it must distribute to the beneficiaries. Conversely, the beneficiaries are taxed on that distributed income, even if they do not physically receive it until after the close of the taxable year. Consequently, the trust typically ends up with little or no taxable income because the deduction for distributed income offsets what would otherwise be taxable at the trust level.

Key Attributes of a Simple Trust

• Mandatory Distributions: The trustee must distribute trust accounting income (TAI) in the year it is earned. If the trust omits or defers the distribution, it can lose its classification as a simple trust for that year.
• No Charitable Gifts: Simple trusts do not make charitable gifts during the year. If a trust instrument includes a clause allowing or requiring charitable contributions, or if the trustee contributes principal or income to charity, the trust may be considered complex.
• No Principal Distributions: All distributions must come out of income, not principal. Distributing principal to beneficiaries generally makes the trust complex for that year.

Taxation and Reporting

For tax compliance, the trust files Form 1041 (U.S. Income Tax Return for Estates and Trusts). On Form 1041, the trust reports gross income, deductions, and the distribution deduction for the amounts deemed to have been distributed. The beneficiaries receive a Schedule K-1 from the trust, which indicates the portion of trust income they must report on their personal tax returns.

	    B --> C[Trust Takes Distribution Deduction on Form 1041]
	    B --> D[Beneficiaries Receive Income/ K-1 Allocation]
	    D --> E[Beneficiaries Pay Tax on Received Income]

Explanation:

1. The trust earns income from various sources (interest, dividends, rental income, etc.).
2. Because it is a simple trust, all of the trust’s accounting income must be distributed to the beneficiaries currently.
3. The trust deducts these distributions; therefore, the trust generally pays no or minimal tax.
4. Beneficiaries receive Schedule K-1 statements reporting the income.
5. Beneficiaries include these amounts on their personal tax returns and pay taxes accordingly.

Complex Trusts

A “complex trust” is any trust that does not meet the criteria for a simple trust. A trust can be treated as complex for a tax year if:
• It retains some or all of its income (rather than mandating that all income be distributed currently).
• It makes distributions from principal.
• It makes distributions to charitable entities.

Complex trusts may accumulate income, and the trust pays tax on undistributed income at trust tax rates (which can be quite high at relatively low income levels). Additionally, if the trust distributes some (but not all) of the income, only the portion actually or constructively distributed is included in Distributable Net Income (DNI) allocated to beneficiaries.

Key Attributes of a Complex Trust

• Discretionary Distributions: The trustee has greater flexibility in deciding whether to distribute or retain income.
• Principal Distributions: The trustee may distribute principal to beneficiaries under the terms of the trust instrument.
• Charitable Contributions: Complex trusts can make charitable contributions and claim certain deductions, although the rules differ from those governing individuals.

Example

Consider a testamentary trust designed to pay the living and education expenses of two minor grandchildren. The grantor’s will grants the trustee the discretion to distribute principal if needed for tuition, housing, or other essential expenses. This trust can be complex because it potentially makes distributions from principal (not just income).

Grantor Trust Rules

Under IRC §§ 671–678 (commonly referred to as the “Grantor Trust Rules”), if a trust’s grantor retains certain powers or has specific interests in the corpus, the trust’s income may be taxed directly to the grantor rather than the trust or its beneficiaries. These rules ensure that taxpayers cannot artificially shift income to lower-bracket taxpayers (including trusts or beneficiaries) when they still effectively control or benefit from the trust assets.

Common Powers Triggering Grantor Trust Status

1. Reversionary Interest: A grantor retains a reversionary interest in either the corpus or the income of the trust, which exceeds 5% of the trust’s value at the time of creation (IRC §673).
2. Power to Control Beneficial Enjoyment: The trust instrument grants the grantor (or a non-adverse party) the power to control beneficiaries’ enjoyment of the income or principal (IRC §674).
3. Administrative Powers: Certain administrative powers retained by the grantor can cause the trust to be a grantor trust if they allow the grantor (or a non-adverse party) to deal with trust property for less than adequate consideration or otherwise control trust property in ways that may benefit the grantor economically (IRC §675).
4. Power to Revoke: If the grantor can revoke the trust or reclaim assets at any time, the trust is classified as a grantor trust (IRC §676).
5. Income for the Benefit of Grantor: If the income can be used to pay life insurance premiums on the grantor’s life or otherwise benefit the grantor, the trust is a grantor trust (IRC §677).
6. Power to Substitute Assets: Under certain circumstances, the ability for the grantor to substitute assets of equivalent value can also establish grantor trust classification, depending on the terms and the trustee’s role.

Tax Implications of Grantor Trusts

If a trust is classified as a grantor trust, all items of income, deductions, and credits are reported on the grantor’s individual income tax return. The trust files a Form 1041 as a grantor type trust return, usually a simplified filing indicating that the trust’s income is reportable by the grantor. This treatment allows the grantor to remain primarily responsible for taxes on trust income, often aligning with broader estate planning or tax minimization strategies.

Distribution Requirements and Income Passing

One of the most significant differences in trusts for tax purposes is how trust income passes to the beneficiary and who ultimately bears the tax burden:

1. Simple Trust: By definition, must distribute all of its income every year. The beneficiaries include that distribution in their taxable income.
2. Complex Trust: The trust can accumulate and retain some income, distributing only a portion. Any amounts not distributed remain taxed at the trust level.
3. Grantor Trust: All tax items pass through to the grantor, effectively ignoring the existence of the trust for income tax purposes.

	    C --> F[Beneficiaries Report Income on Personal Returns]
	    D --> G[Portion Distributed -> Beneficiaries; Undistributed -> Trust Pays Tax]
	    E --> H[Trust is "Ignored" for Income Tax Purposes]

Reversionary Powers and Grantor Trust Status

A key concept in the CPA exam coverage relates to reversionary powers (IRC §673). The rules say that if the grantor’s reversionary interest in trust property exceeds 5% of the value of that property at the time of the trust’s creation, the trust is considered a grantor trust as to that property. The logic behind this rule is that the grantor effectively maintains a beneficial stake in the trust’s assets or income, which undermines the claim that the trust is truly separate for income tax purposes.

Example of a Reversionary Interest

Maxwell establishes a trust for his granddaughter, to terminate when she turns 25. If the granddaughter dies before age 25, the trust reverts to Maxwell. At the date of trust creation, the reversionary interest is estimated at nearly 7% of the trust value based on actuarial tables and the granddaughter’s life expectancy. Because this reversionary interest exceeds the 5% threshold, the entire trust would be treated as a grantor trust during the granddaughter’s lifetime until the trust terminates or the conditions causing reversion no longer apply.

Practical Examples & Case Studies

Case Study 1: Conversion from Simple to Complex

The “Wickham Family Trust” is set up to pay all income annually to two adult children, meeting the definition of a simple trust for its first several years. In Year 5, the trustee distributes principal to one child to help with a down payment on a home. That principal distribution causes the trust to be treated as a complex trust for Year 5. However, in Year 6, if the trustee reverts to only distributing income, the trust may be classified again as a simple trust for Year 6.

Case Study 2: Grantor Retains Power to Substitute Assets

A wealthy individual, Gabriella, establishes a trust naming her child as beneficiary. The trust instrument grants Gabriella the right to substitute assets of equivalent value without requiring the beneficiary’s or a trustee’s approval. Because of this retained power, the trust is considered a grantor trust. All of the trust’s income, deductions, and credits flow through to Gabriella’s personal tax returns. The trustees file a Form 1041 indicating grantor trust status, but no separate trust-level tax is paid.

Common Pitfalls and Best Practices

1. Beware of Accumulating Income in Simple Trusts: Even a single year of failing to distribute all trust income may inadvertently convert a simple trust to a complex trust, impacting compliance and tax rates.
2. Monitoring Distribution Timing: If a trust distribution is made within 65 days following the close of the trust’s tax year, under IRC §663(b) (the “65-day rule”), it may still be treated as distributed in the prior year, offering potential planning opportunities.
3. Accurate Valuation for Reversionary Interests: Determining whether a trust is a grantor trust due to reversionary powers often involves complex actuarial calculations. Always ensure valuations reflect the trust’s actual economic realities.
4. Maintaining Proper Documentation: If a trust is a grantor trust, transparent recordkeeping simplifies consolidation with the grantor’s personal return and clarifies the trust’s tax treatment.

Study Tips for the CPA Exam

• Understand Subchapter J: Familiarize yourself with IRC §§ 641–692. Pay special attention to the definitions of DNI, personal exemption rules, and distribution deductions.
• Work Through Trust Tax Examples: Practice computing trust-level income, distribution deductions, and beneficiary-level reporting.
• Memorize Key Grantor Trust Triggers: You can expect questions about the presence of reversionary interests, revocation powers, and administrative controls.
• Engage with Real-World Scenarios: Reviewing actual trust documents or practicing with hypothetical trust instruments helps solidify abstract concepts.
