Section 643(e)(3) Election: How It Works and When to Use It

The Section 643(e)(3) election lets the fiduciary of an estate or complex trust treat an in-kind property distribution as if the entity sold the property to the beneficiary at fair market value on the distribution date. The entity recognizes gain or loss immediately, the distribution deduction is based on fair market value rather than the lower of basis or value, and the beneficiary takes the property with a fair-market-value basis. The election is made annually on Form 1041, applies to every property distribution during the tax year, and is effectively irrevocable once the return is filed.¹

What Changes When You Elect

Without the election, three default rules govern an in-kind distribution. The entity recognizes no gain or loss. The beneficiary takes the property with a carryover basis equal to the entity’s adjusted basis. And the distribution counted for deduction and income-inclusion purposes is the lesser of the property’s adjusted basis or its fair market value.¹

Making the election flips two of those rules. The entity treats the transfer as a deemed sale at fair market value and recognizes the built-in gain or loss. The distribution deduction is measured by fair market value. And because the beneficiary’s basis equals the entity’s adjusted basis plus any gain (or minus any loss) recognized on the distribution, the arithmetic always leaves the beneficiary with a basis equal to fair market value.¹

Take stock with a $30,000 basis and a $100,000 fair market value. Under the default rules, the trust recognizes nothing, deducts $30,000, and the beneficiary receives the stock with a $30,000 basis. Under the election, the trust recognizes a $70,000 capital gain, deducts $100,000, and the beneficiary receives the stock with a $100,000 basis. The gain has moved from the beneficiary’s future sale to the entity’s current return, and where that gain ultimately gets taxed depends on how it flows through Distributable Net Income.

Who Can Elect and What the Election Covers

Only fiduciaries of estates and complex trusts can make the election. Simple trusts are excluded because the statute references Sections 661 and 662, and simple trusts operate under Sections 651 and 652.¹ A normally-simple trust that distributes corpus in a given year becomes complex for that year, and the election is available then.

The fiduciary decides on their own. Beneficiary consent is not required. Three constraints govern how the election operates:

It is all-or-nothing for the year. Every property distribution the entity makes during the tax year is covered. You cannot pick assets or beneficiaries.¹
It is an annual decision. Electing this year does not bind you next year.
It is effectively irrevocable. Revocation requires the consent of the Secretary of the Treasury, so once you file, you are locked in for the year.¹

The all-or-nothing rule is the constraint fiduciaries most often underestimate. If an estate distributes three assets in one year, two with gains and one with a loss, the election triggers recognition on all three. Splitting distributions across tax years is often the only way to sort assets with different gain and loss profiles into different treatments.

How To Make the Election on Form 1041

The election is made on the entity’s Form 1041. The IRS instructions direct the fiduciary to check the designated box in the “Other Information” section and attach a completed Schedule D (Form 1041) reporting the recognized gains and losses.² For each distributed asset, gain or loss is the difference between fair market value on the distribution date and the entity’s adjusted basis.

The election must be made on the return for the tax year in which the distributions occur.¹ For calendar-year estates and trusts, the 2025 Form 1041 is due April 15, 2026, and an extension preserves the ability to make the election on the extended return.²

Schedule K-1 (Form 1041) reports each beneficiary’s share of income. When the election is in effect, the K-1 reflects fair market value rather than adjusted basis for property distributions.² The K-1 has no line for basis, so send the beneficiary a written notice of their new basis in the property. That single document prevents disputes years later when the beneficiary sells.

How the Election Moves Income Through DNI

Distributable Net Income is the ceiling on the entity’s distribution deduction and the floor on the beneficiary’s income inclusion. The election pushes DNI in two directions at once.

The distribution deduction goes up, because it is now based on fair market value. For appreciated property, the larger deduction reduces the entity’s taxable income.

The recognized capital gain may or may not enter DNI. Under the general rule, capital gains allocated to corpus stay at the entity level. Gains flow into DNI when they are allocated to income under the governing instrument or local law, when they are allocated to corpus but actually distributed to the beneficiary, or when the fiduciary uses them in determining the distribution amount.³ When property is distributed in kind and the election is made, the “actually distributed to the beneficiary” prong is often satisfied because the asset producing the gain is the same asset going out the door. The gain then flows to the beneficiary on the K-1, and the beneficiary pays the tax.

If the election produces a loss, that loss offsets the entity’s other capital gains. A net capital loss can offset up to $3,000 of the entity’s ordinary income, with any excess carried forward indefinitely.⁴ The loss reduces DNI, so less income flows out to beneficiaries.

Why the Trust Brackets Make This Decision Matter

Estates and trusts reach the top federal bracket at income levels that would barely register on an individual return. For 2026, the ordinary rate schedule runs:

10% on taxable income up to $3,300
24% on income from $3,301 to $11,700
35% on income from $11,701 to $16,000
37% on income over $16,000⁵

Long-term capital gains for 2026 sit at 0% up to $3,300, 15% from $3,301 to $16,250, and 20% above $16,250. The 3.8% net investment income tax applies to undistributed net investment income over $16,000.⁵

A trust that retains a $70,000 capital gain hits a combined 23.8% on nearly all of it. If the beneficiary sits in the 15% capital gains bracket, moving that gain out through DNI via the election can produce meaningful savings. If the beneficiary is already at 20% plus net investment income tax, or the gain will fall to corpus and stay at the entity, the election may increase total taxes paid. Model both scenarios before filing.

When Losses Get Disallowed

The election’s ability to trigger loss recognition collides with the related-party rules under Section 267. That statute disallows losses on sales or exchanges between certain related parties, and fiduciary-beneficiary relationships are on the list.⁶

For a trust, a fiduciary and any beneficiary of that trust are related parties, so a loss recognized on distributing depreciated property to a beneficiary is disallowed. The trust triggers the deemed sale but cannot use the loss. For an estate, the executor and beneficiaries are related parties too, with one carve-out: losses on distributions that satisfy a pecuniary bequest, meaning a bequest of a specific dollar amount, are not disallowed.⁷ Identify loss assets before electing, and check whether Section 267 would swallow the loss you were trying to capture.

When the Election Pays Off, and When It Backfires

The election tends to save tax in two recurring situations. First, the entity has little other income and any retained capital gain would land in the compressed trust brackets, while the beneficiary sits in a lower individual bracket. Pushing a $100,000 gain out to a beneficiary in the 15% capital gains bracket saves roughly $8,800 versus letting the trust absorb it at 23.8%. Second, the entity has capital losses that can absorb the recognized gain. A trust with $60,000 in carryover losses that distributes property with a $50,000 built-in gain can recognize the gain, offset it entirely, and deliver a stepped-up basis to the beneficiary at no net tax cost.

The election is least attractive when the all-or-nothing rule drags large gains along with a single desired loss, when the beneficiary is already at 20% plus net investment income tax, or when Section 267 will disallow the loss the fiduciary was chasing. Because the election is irrevocable once the return is filed, run the numbers both ways: the difference between electing and not electing can easily reach five figures on a moderately sized estate or trust.

Specific Bequests and the 65-Day Rule

Two adjacent rules are worth flagging so you do not apply Section 643(e)(3) where it does not belong.

Distributions satisfying a bequest of a specific sum of money or specific property fall outside Section 643(e) entirely. They are excluded from the entity’s distribution deduction and from the beneficiary’s income under Sections 661 and 662, provided the bequest is paid in no more than three installments. When an estate uses appreciated property to satisfy a pecuniary bequest, gain recognition happens automatically under existing regulations without any election.⁸ Keep specific bequests and residuary distributions on separate tracks.

Complex trusts, but not estates, can elect under Section 663(b) to treat distributions made within the first 65 days of a new tax year as made on the last day of the prior year for all purposes.⁹ If a property distribution in January or February is pulled back to the prior year, the 643(e)(3) election for that distribution belongs on the prior year’s Form 1041, and the all-or-nothing rule for the prior year must account for it. Coordinate both elections on the same return.
