What Is the Charitable Deduction for Estates and Trusts?

Estates and complex trusts can claim an unlimited charitable deduction for estates and trusts under Internal Revenue Code Section 642(c), reducing taxable income dollar-for-dollar for amounts of gross income paid to a qualified charitable purpose. Unlike individuals, who face percentage-of-income caps, a fiduciary entity can potentially zero out its taxable income through charitable giving, so long as the will or trust document authorizes the payment and the money comes from the entity’s gross income. The deduction is computed on Schedule A of Form 1041 and reduces the entity’s income before distributable net income is calculated.¹

Which Estates and Trusts Can Use the Deduction

Section 642(c) is available to estates during administration and to complex trusts. A complex trust is any trust that accumulates income, distributes principal, or makes charitable contributions; if the governing document authorizes charitable giving and the trust makes a payment, it is treated as complex for that year.

Simple trusts cannot use the deduction. By definition, a simple trust distributes all current income to beneficiaries and has no charitable provision, so the statute excludes trusts “meeting the specifications of subpart B.”² Charitable remainder trusts and pooled income funds are also outside Section 642(c); they compute charitable deductions under separate rules.

The Two Requirements That Make or Break the Deduction

Every claim under Section 642(c) rests on two conditions. Miss either and the deduction is gone.

First, the governing instrument must authorize the payment. If the will or trust does not contain language permitting charitable distributions, no deduction is available. A general power to make distributions is usually not enough; the document should reference charitable giving or contributions to organizations described in Section 170(c).² A surprising number of claims fail here, because fiduciaries assume authority exists when the instrument never grants it.

Second, the payment must come from the entity’s gross income for the taxable year. Gross income includes interest, dividends, rents, royalties, business income, and capital gains recognized by the entity. Payments made from corpus do not qualify for the income tax deduction. When a payment is funded partly from income and partly from principal, only the income portion is deductible, and the fiduciary needs to document the allocation.

Capital Gains Are Usually Not Deductible

Capital gains can be included in the deduction only if the governing instrument or applicable local law allocates gains to income rather than to principal.¹ Most trust instruments default gains to principal, which keeps them out of the deduction even when the charitable payment easily covers them. Check the document and state law before assuming the gains count.

Tax-Exempt Income Reduces the Deduction

If the estate or trust holds municipal bonds or other tax-exempt investments, the charitable deduction must be reduced by the portion allocable to that tax-exempt income. The income was never taxed in the first place, and the IRS does not let it generate a deduction on the way out.

If the governing instrument specifies the source of the charitable payment, that controls. Otherwise, apply a proportional formula: multiply the total charitable payment by a fraction with tax-exempt income on top and total gross income (excluding losses allocated to corpus) on the bottom. The result is the non-deductible portion.¹ For entities with meaningful municipal bond holdings, this can shrink the expected benefit noticeably.

Foreign Charities Qualify

Individual donors generally cannot deduct a gift to a foreign charity under Section 170, because the recipient must be an organization created or organized in the United States.³ Section 642(c) sets that limit aside. It allows the deduction for amounts paid “for a purpose specified in section 170(c) determined without regard to section 170(c)(2)(A),” which is the domestic-organization requirement.² An estate or trust can therefore deduct a payment to a foreign organization operating for religious, charitable, scientific, literary, or educational purposes.

Paid vs. Permanently Set Aside

Section 642(c) covers amounts actually paid and, in limited circumstances, amounts permanently set aside for charity. The two tracks work differently.

Estates can deduct income permanently set aside for charity under the terms of the will before the money is actually distributed, provided the possibility that the funds will not reach the charitable purpose is “so remote as to be negligible.”⁴ Any realistic chance that the estate might need to invade those funds for other obligations defeats the deduction.

Trusts have a much narrower path. Only trusts created on or before October 9, 1969 can claim the set-aside deduction, and only on income earned from assets transferred to the trust before that date.² For any trust created after that date, the money has to be paid to generate the deduction.

The Election to Treat Next Year’s Payment as This Year’s

Fiduciaries have a timing tool worth knowing. A charitable contribution paid after the close of the taxable year but on or before the last day of the following taxable year can be treated as if paid in the earlier year.² For a calendar-year estate or trust, a payment made any time during 2027 can be deducted on the 2026 Form 1041.

Making the election requires a statement attached to the Form 1041 for the year the payment is being treated as made. The statement should include:

The name and address of the fiduciary and identification of the estate or trust.
A declaration that the fiduciary is electing under Section 642(c)(1) to treat the contributions as paid during the earlier year.
The name and address of each charitable recipient.
The dollar amount and actual payment date of each contribution.

The election must be filed no later than the due date, including extensions, for the return of the year the payment was actually made. After that deadline, the election is irrevocable; before it, the fiduciary can revoke.⁵

When “Unlimited” Gets a Ceiling: Unrelated Business Income

The unlimited label has one real exception. Under IRC Section 681, when a trust earns unrelated business taxable income (UBTI), the charitable deduction allocable to that income is subject to the same percentage caps that apply to individuals.⁶ The purpose is to stop trusts from using Section 642(c) to wipe out income from an active trade or business.

The deduction for the UBTI portion is capped at 50% of UBTI for contributions to public charities and 30% for other qualifying organizations.⁷ The set-aside deduction is not available against UBTI; only amounts actually paid qualify.⁸ Excess contributions may carry forward for up to five years. Section 681 applies to trusts only. Estates are not subject to this limitation.

Non-Cash Gifts and Appraisal Rules

Fiduciaries often donate appreciated property such as real estate, art, or closely held business interests. Non-cash gifts carry extra documentation.

Any donated property valued above $5,000 requires a qualified appraisal. The appraiser must be qualified, the appraisal must be signed and dated no earlier than 60 days before the donation, and the fiduciary must receive it before the due date (including extensions) of the return claiming the deduction. The appraiser’s fee cannot be based on a percentage of the appraised value.⁹

Items requiring a qualified appraisal are reported on Section B of Form 8283, attached to the Form 1041. A complete copy of the signed appraisal must also be attached when the deduction for donated art is $20,000 or more, or when the deduction for any single item or group of similar items exceeds $500,000.⁹

Reporting on Schedule A of Form 1041

The deduction is computed on Schedule A of Form 1041. Line 1 captures total amounts paid or permanently set aside for charitable purposes out of gross income, including any eligible capital gains. Line 2 subtracts the portion allocable to tax-exempt income (using the proportional formula above, unless the governing instrument specifies a source). Line 3 subtracts any Section 1202 capital gains exclusion adjustment, if applicable. The result flows to the front page of Form 1041 and reduces total income before the income distribution deduction and exemption amount are applied.¹

Keep more than you file. Hold onto the governing instrument showing authorization, bank records for each transfer, acknowledgment letters from each recipient, and any qualified appraisals. If you use the timing election, keep the election statement and records showing both the actual payment date and the year to which the deduction is applied.

Penalties for Overstating the Deduction

Overstatements carry teeth. Under IRC Section 6662, a substantial valuation misstatement on a charitable deduction triggers a 20% accuracy-related penalty on the resulting underpayment, and a gross valuation misstatement doubles that to 40%.¹⁰ For charitable deduction overstatements specifically, a 50% penalty can apply.

These penalties bite hardest on non-cash gifts, where valuation is subjective. A qualified appraisal is both a filing requirement and the fiduciary’s primary defense if the IRS challenges the number later.
