Yes, a trust can pay income taxes instead of its beneficiaries, but only on income the trustee keeps inside the trust rather than distributing. The pass-through works in one direction: whatever the trustee sends out to beneficiaries gets taxed to them, and whatever stays behind gets taxed to the trust. The catch is that trusts hit the top 37% federal rate at just $16,000 of taxable income for 2026, so keeping income inside the trust is usually the expensive choice.1Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts
Who Pays Depends on Where the Income Goes
Trust income tax follows a pass-through principle. Income retained by the trust is taxed to the trust. Income distributed to beneficiaries is taxed to them on their personal returns, and the trust claims a deduction for what it distributed so the same dollar isn’t taxed twice.2Internal Revenue Service. 2025 Instructions for Form 1041 and Schedules A, B, G, J, and K-1 That single mechanic is what lets a trustee choose, within limits, which pocket pays the bill.
The limits come from two places: the type of trust, which determines whether the trustee has any choice at all, and a concept called distributable net income, which caps how much can shift to beneficiaries in a given year.
The Trust Type Often Decides the Question
Grantor Trusts
If the trust is a grantor trust, neither the trust nor the beneficiaries pay the income tax. The grantor does. A grantor trust is one where the person who created it kept enough control that the IRS ignores the trust for income tax purposes and treats all income, deductions, and credits as the grantor’s.3Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners Revocable living trusts are the common example. Beneficiaries of a grantor trust don’t report the trust’s income, and the trust typically doesn’t file its own return. The question of shifting tax to the trust or the beneficiaries doesn’t really apply.
Simple Trusts
A simple trust is required by its governing document to distribute all income every year. It can’t make charitable gifts and can’t distribute principal.4Office of the Law Revision Counsel. 26 USC 651 – Deduction for Trusts Distributing Current Income Only Because the income has to go out, the beneficiaries pay the tax on ordinary income, not the trust. The trustee has no discretion to hold income back.
Complex Trusts
Complex trusts are where the choice actually exists. The trustee has discretion to accumulate income inside the trust, distribute income, distribute principal, or send money to charity.5Office of the Law Revision Counsel. 26 USC 661 – Deduction for Estates and Trusts Accumulating Income or Distributing Corpus Whatever the trustee retains, the trust pays tax on. Whatever the trustee distributes, the beneficiaries pay tax on. This is the type of trust the searcher’s question really applies to.
Distributable Net Income Caps the Shift
Distributable net income (DNI) is the ceiling on how much trust income can be taxed to beneficiaries in a given year. It’s essentially the trust’s taxable income before the distribution deduction, with adjustments.6Office of the Law Revision Counsel. 26 USC 643 – Definitions Applicable to Subparts A, B, C, and D
An example makes it concrete. A complex trust earns $10,000 of interest and dividends, giving it $10,000 of DNI. If the trustee distributes $8,000, the beneficiary reports $8,000 and the trust pays tax on the remaining $2,000. If the trustee distributes the full $10,000, the beneficiary pays all the tax and the trust owes nothing on that ordinary income.
Distributions beyond DNI don’t shift more tax. Anything above DNI is treated as a tax-free return of principal to the beneficiary.7Internal Revenue Service. SOI Tax Stats – Definitions of Selected Terms and Concepts for Income From Trusts and Estates A trust with $10,000 of DNI that distributes $15,000 taxes the beneficiary on $10,000 and hands over $5,000 tax-free. The trust’s distribution deduction also stops at DNI.
Why Trustees Usually Distribute
The federal brackets for trusts are far more compressed than individual brackets. An individual single filer doesn’t reach 37% until taxable income passes roughly $626,000. A trust reaches 37% at $16,000. The full 2026 schedule:1Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts
- 10% on taxable income up to $3,300
- 24% from $3,301 to $11,700
- 35% from $11,701 to $16,000
- 37% above $16,000
A trust that keeps $50,000 of ordinary income pays substantially more tax than a beneficiary in a middle bracket would pay on the same amount. That’s the arithmetic behind why most trustees distribute whenever the trust document permits and the beneficiaries’ situations make sense.
On top of ordinary income tax, retained investment income can trigger the 3.8% net investment income tax. The trust owes NIIT on the lesser of undistributed net investment income or the amount by which its adjusted gross income exceeds the top-bracket threshold.8Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax For 2026 that threshold is the same $16,000 where the 37% bracket starts. A trust with $50,000 of retained investment income owes 3.8% on $34,000, roughly $1,290 on top of income tax. Distributing that income to beneficiaries pushes the NIIT question onto their returns, where their own thresholds and situations apply.
Capital Gains Usually Stay With the Trust
Capital gains follow different rules from interest and dividends. By default, gains realized by a trust are allocated to principal rather than income, which means they’re excluded from DNI and can’t be passed through to beneficiaries on the K-1. The trust pays the tax on those gains.6Office of the Law Revision Counsel. 26 USC 643 – Definitions Applicable to Subparts A, B, C, and D
There are exceptions. Gains join DNI when the trust document or state law allocates them to income, when the trustee consistently treats them as part of distributions on the trust’s books, when they’re actually distributed to a beneficiary, or in the trust’s final year. The language of the governing document matters a great deal here, and trustees who want the flexibility to pass gains through need a document drafted with that option in mind.
When gains stay with the trust, the compressed brackets bite again. The 20% long-term capital gains rate arrives at a much lower income level than it does for individuals, and NIIT applies on top once income exceeds $16,000.
The 65-Day Rule Gives Trustees a Second Look
A trustee rarely knows in December exactly what a trust earned or what the optimal distribution would be. The 65-day rule solves that. Distributions made in the first 65 days of a new tax year can be elected to count as if they were made on the last day of the prior tax year.9Justia Law. 26 USC 663 – Special Rules Applicable to Sections 661 and 662 With the year’s actual numbers in hand, the trustee can push income out retroactively and let the beneficiaries pay at their rates instead of leaving it stuck at the trust’s compressed rates.
The election is made by checking a box on Form 1041 and is irrevocable for that year. Miss the window and the chance to shift that year’s income is gone.
Charitable Remainder Trusts Sit Outside This Framework
A properly structured charitable remainder trust is exempt from federal income tax on its earnings entirely.10eCFR. 26 CFR 1.664-1 – Charitable Remainder Trusts The trust pays annuity or unitrust amounts to a non-charitable beneficiary, and that beneficiary reports the payments on their personal return under a tiering system that treats the most heavily taxed income as distributed first. The remainder eventually goes to a qualified charity. CRTs don’t follow the DNI framework described above and have their own qualification and excise tax rules.
State Taxes Add Another Layer
Federal rules don’t finish the picture. Most states with an income tax also tax trust income, and the tests for whether a trust is a “resident” of the state vary. Common factors include where the trust was created, where the grantor lived, where the trustee is located, where the trust is administered, and where the beneficiaries reside. Combined federal and state tax on retained trust income can push the effective rate above 40%, which sharpens the incentive to distribute whenever the trust document allows it.
