Electing Small Business Trust (ESBT)

What Are the ESBT Requirements?

An electing small business trust qualifies on three conditions, and the second one ends more plans than the other two together.

1. Every potential current beneficiary is eligible. Each one must be an individual who is a US citizen or resident, an estate, or a qualifying charitable or retirement organization. A corporation, a partnership or an LLC anywhere in the beneficiary pool disqualifies the trust. Since the 2017 tax act a non-resident alien may sit in that pool, which opened the structure to families with relatives abroad.
2. The stock did not arrive by purchase. The trust must have received the S-corporation stock by gift, bequest or contribution. A trust that bought in, including an installment sale to an intentionally defective grantor trust, cannot use the ESBT at all.
3. The trustee makes the election. The trustee files within 2 months and 16 days after the trust becomes a shareholder, at the service center where the corporation files. The election is irrevocable without IRS consent.

Practice pointer. Ask how the stock arrived before you ask anything else. A note sale is the standard technique for freezing value in a family business, and it is also the one fact that removes the ESBT from the menu, which means the estate plan and the sale structure have to be designed in the same conversation rather than in sequence.

How Is an ESBT Taxed?

An ESBT is split in two for tax purposes. The S portion, meaning the S-corporation stock and everything it produces, is treated as a separate taxpayer taxed at a flat 37% from the first dollar. The non-S portion is taxed under the ordinary trust rules, including the deduction a trust takes for distributions to its beneficiaries.

The flat rate has no graduation and no relationship to the beneficiaries’ own brackets. A trust holding a company that throws off $100,000 a year pays roughly $37,000, where a single beneficiary at a 24% marginal rate holding the same stock through a qualified subchapter S trust would pay about $24,000. The 3.8% net investment income tax can sit on top of that where the income is passive to the trust.

Two further limits belong in the same paragraph as the rate. The charitable deduction a trust normally takes for income set aside for charity is unavailable against the S portion. Fiduciary fees and administrative expenses are deductible against the S portion only to the extent they are allocable to it.

What the ESBT Buys You

The flexibility is real, and for some families it is worth the rate.

An ESBT may have unlimited eligible beneficiaries, where a QSST is confined to one at a time. An ESBT may accumulate income rather than distribute it, where a QSST must pay out everything it earns. Those two differences are what make a dynasty trust, a discretionary family trust or a generation-skipping trust workable as a shareholder at all.

The accumulation feature also solves a human problem rather than a tax one. A beneficiary with creditor exposure, an active disability, or a pattern of spending the trust was written to manage should not receive the full income of a family company every year. A QSST would force that money out the door. An ESBT lets a trustee hold it.

The Shareholder Count Nobody Checks

An S corporation may have no more than 100 shareholders, and an ESBT counts one shareholder for every potential current beneficiary. A QSST counts one, the current income beneficiary.

Avoid drafting a broad discretionary class into a trust that will hold S-corporation stock without counting it. A class defined as the settlor’s descendants and their spouses can run to a dozen people on the day it is signed and grow every year after, and each of them consumes a slot the company may need for a key employee or an incoming family member.

Where an ESBT Fails

A beneficiary added later. The eligibility test applies continuously, not only at signing. A distribution committee that adds a beneficiary, or a beneficiary who forms an entity that becomes a permissible recipient, can disqualify a trust that qualified for years.

A purchase nobody flagged. The stock has to have arrived by gift, bequest or contribution, and the answer sits in documents the current advisers may never have seen.

An election used as a shelter. An ESBT election changes how a trust is taxed on S-corporation income. It does not change who is taxed when the trust is a grantor trust, because a grantor trust’s income remains the grantor’s income.

Relief for a genuinely inadvertent termination runs through a simplified IRS procedure or a private letter ruling, and a ruling commonly costs $40,000 to $50,000 plus professional fees.

What I See in These Files

In 14 years of law practice, I have watched families reach for the ESBT because they want the flexibility, before anyone has priced the rate for them. The flexibility is genuine. The rate is also genuine, and it arrives every year for as long as the trust holds the stock.

A common question I hear is, "If the trust pays the tax, does that make the rate somebody else’s problem?" It does not, and I have come across a group of business families who learned that the expensive way. They found a version of this that looked too good to leave alone. Each of them moved company stock into a trust the owner could still revoke, elected ESBT status for it, and then reported the business income as the trust’s income rather than as their own. One family’s trusts collected more than $16 million on a sale in February 2000 and claimed a refund of over $2 million on the strength of that reporting. The reasoning was not absurd. The statute was new, the election was real, and the returns were filed openly.

They lost, and they lost together. An ESBT election changes how a trust is taxed. An ESBT election does not change who is taxed, because income of a trust the settlor can still revoke remains the settlor’s income, election or no election.

One family in that group got something back, and I point clients at it for the opposite reason. They recovered a penalty of $359,822, because they had disclosed the trust’s ownership on the return and their reading of an unsettled statute had been reasonable when they took it.

Practice pointer. State an aggressive position openly on the return. Disclosure is what makes good faith credible later, and the same position taken quietly reads as something else entirely once an examiner finds it.

The honest limit is that the choice between an ESBT and a QSST turns on facts this page cannot see. How many beneficiaries, what brackets they sit in, whether income needs to stay in the trust, and how the stock arrived all move the answer, and the election is close to permanent once filed.
