Charitable Deductions for Trusts & Estates
§642(c): Different Rules, Different Traps

How §642(c) works

Section 642(c) allows a trust or estate to deduct amounts of gross income that are, pursuant to the terms of the governing instrument, paid or permanently set aside for a charitable purpose described in §170(c). This is not the same deduction that individuals claim under §170. The rules are structurally different in several important ways.

No percentage-of-AGI limitations

Individuals face percentage caps on charitable deductions: 60% of AGI for cash to public charities, 30% for capital gain property, 20% for certain private foundation contributions, and so on. Trusts and estates have no such limits under §642(c). If the trust’s entire gross income is paid to charity pursuant to the governing instrument, the entire amount is deductible.

This can make the §642(c) deduction more powerful than an individual deduction in some cases, particularly for trusts with large income and charitable mandates.

The gross income requirement

The deduction is limited to amounts paid from the trust’s or estate’s gross income. Contributions from corpus (principal) are not deductible under §642(c). This is the most common trap.

In practice, this requires tracing. When the trust writes a check to a charity, the question is whether the funds came from income or principal. If the trust has both income and principal, and the governing instrument or state law provides that charitable contributions come from income, the deduction is supportable. If the contribution comes from principal (or the source is unclear), the deduction may be denied.

The determination of “gross income” follows tax law concepts, not trust accounting concepts. Trust accounting income (under UPIA or the governing instrument) and tax gross income often overlap, but they are not identical. Capital gains, for example, are typically allocated to principal under trust accounting but are included in gross income for tax purposes. Whether a charitable contribution from capital gain proceeds qualifies for the §642(c) deduction depends on whether the governing instrument authorizes it and whether the payment is properly sourced to gross income.

Governing instrument authorization

The deduction is available only if the charitable contribution is made pursuant to the terms of the governing instrument. If the will or trust document does not authorize charitable giving, no deduction under §642(c) is available, regardless of how worthy the charity or how large the contribution.

The authorization does not have to be specific. Broad language granting the trustee or executor discretion to make charitable contributions is generally sufficient. But the language must be in the governing instrument itself; a separate trustee resolution or a state-law default is not enough.

This is a planning point that matters at the drafting stage. If charitable giving is anticipated, the trust or will should include explicit authorization.

No carryforward

Unlike individuals, who can carry forward unused charitable deductions for up to five years, trusts and estates get no carryforward under §642(c). If the charitable contribution exceeds gross income in a given year, the excess is lost. It cannot be carried forward to a future year.

This makes timing important. A trust should coordinate the timing of charitable contributions with years when it has sufficient gross income to absorb the full deduction.

The election for next-year contributions

Section 642(c)(1) provides an election that allows a trust or estate to treat a charitable contribution made in the taxable year immediately following the close of the current taxable year as if it were paid during the current taxable year. This is similar in concept to the 65-day rule under §663(b), but it applies specifically to charitable contributions.

The election must be made on a timely filed return (including extensions) for the year in which the deduction is claimed. The contribution must actually be paid during the following taxable year.

This provides flexibility: if the trustee realizes after year-end that the trust has taxable income that could be offset by a charitable deduction, a contribution made early in the next year can be treated as a current-year deduction.

Permanently set aside (estates only)

For estates, §642(c) allows a deduction for amounts “permanently set aside” for charitable purposes, even if the funds have not yet been physically transferred. This is not available to trusts (unless the trust was created before October 9, 1969, and meets certain conditions under §642(c)(2)).

The “permanently set aside” test requires that the amount is irrevocably committed to charity. If there is any possibility that the funds could be diverted to a non-charitable purpose, the deduction is denied.

Interaction with DNI and distributions

The §642(c) deduction is taken “above the line” in computing the trust’s taxable income. It reduces the trust’s distributable net income (DNI), which in turn affects the amount of income that passes through to beneficiaries on their K-1s.

If a trust has $100,000 of gross income, pays $20,000 to charity under §642(c), and distributes $50,000 to beneficiaries, the DNI is reduced by the charitable deduction. The beneficiaries report a smaller share of income, and the trust’s taxable income is also reduced. The charitable deduction, in effect, benefits both the trust and the beneficiaries by shrinking the overall tax pie.

Distinction from §170

Trusts and estates claim charitable deductions under §642(c), not §170. The two provisions are different in structure:

• §642(c): from gross income, pursuant to the governing instrument, no percentage limits, no carryforward
• §170: available to individuals (and grantor trusts, where the grantor claims the deduction on their own return), subject to AGI percentage limits, with a five-year carryforward

A non-grantor trust cannot claim a deduction under §170. The §642(c) deduction is the exclusive mechanism.

Common pitfalls

• Making a charitable contribution from a trust whose governing instrument does not authorize charitable giving. No deduction is available
• Failing to trace the contribution to gross income. Contributions from corpus are not deductible
• Assuming unused charitable deductions carry forward. They do not for trusts and estates
• Reporting the deduction under §170 instead of §642(c) on the Form 1041
• Missing the election to treat a next-year contribution as current-year. The election must be made on the timely filed return
• Overlooking the DNI interaction. The deduction reduces DNI, which affects beneficiary K-1s

What we need to evaluate the deduction

• Governing instrument: trust document or will (to confirm charitable authorization)
• Income records: the trust’s or estate’s gross income for the year, broken down by source
• Charitable contribution details: recipient, amount, date, and source of funds (income vs. principal)
• Prior year returns: to track any patterns in charitable giving and income levels
• Distribution schedule: amounts distributed to beneficiaries, to coordinate the DNI impact
