Estate and Trust Tax Deductions: Distributions, Fees, and Losses

Estate and trust tax deductions are the levers a fiduciary uses to keep income from being taxed at the entity’s compressed federal rates. On Form 1041, an estate or non-grantor trust can deduct income distributed to beneficiaries, administration and fiduciary expenses, charitable gifts authorized by the governing document, state and local taxes and certain interest, capital losses, and a small statutory exemption. Each one pulls income out of a bracket structure that hits the top 37% federal rate at just $16,250 of taxable income in 2026, so even modest deductions produce outsized savings.

One boundary before going further. If you created a revocable living trust or another arrangement where you retain control over the assets, you likely have a grantor trust, and its income and deductions belong on your personal return rather than a separate Form 1041.¹ Everything below applies to estates and non-grantor trusts.

Why the Bracket Compression Changes Everything

Individual taxpayers don’t reach the 37% federal bracket until their taxable income exceeds several hundred thousand dollars. Estates and non-grantor trusts get there at roughly $16,250. A trust earning $50,000 pays roughly the same marginal rate as an individual earning over $600,000. That is why the deduction for income distributed to beneficiaries is the single most powerful tool in trust taxation, and why the other deductions matter so much whenever income has to stay inside the entity.

The Income Distribution Deduction

The income distribution deduction lets the estate or trust subtract the income it distributes to beneficiaries. That income is then taxed on the beneficiary’s personal return instead of inside the entity’s compressed brackets. For a trust in the 37% bracket distributing to a beneficiary in the 22% bracket, the savings on every distributed dollar are substantial.

The deduction is capped by Distributable Net Income, or DNI. DNI represents the entity’s actual economic income for the year and prevents a fiduciary from claiming an income tax deduction for what is really a distribution of principal. If the trust distributes more than its DNI, the deduction stops at the DNI amount, and the excess reaches the beneficiary as a tax-free return of principal.

For the deduction to work, the fiduciary must either be required to distribute income under the governing document or must exercise discretion to pay it out. The beneficiary reports the distributed amount on their personal return. The fiduciary communicates the amounts and character of the distributions on Schedule K-1, which must be provided to each beneficiary by the Form 1041 filing deadline.²

The 65-Day Rule for Trusts

Trust fiduciaries sometimes realize after year-end that they should have distributed more income. Section 663(b) gives a second chance. A trustee can make a distribution within the first 65 days of the new tax year and elect to treat it as paid on the last day of the prior year.³ For a calendar-year trust, that means a distribution made by March 6 (or March 7 in a leap year) can be applied against the prior year.

The amount eligible cannot exceed the greater of the trust’s accounting income or its DNI for the prior year, reduced by amounts already distributed during that year. The election applies only to the specific year for which it is made and must be indicated on the trust’s Form 1041. It applies to trusts only, not estates.

Administration and Fiduciary Expenses

Running an estate or trust generates attorney fees, accounting charges, appraisal expenses, and fiduciary commissions for the executor or trustee. These qualify as deductions if they are ordinary and necessary for proper administration and the amounts are reasonable.

The fiduciary has an important choice about where to claim them. Under Section 642(g), the same expense cannot be deducted on both the income tax return (Form 1041) and the estate tax return (Form 706). But the rule is more flexible than many fiduciaries realize. Expenses can be split: one item claimed on the income tax return, another on the estate tax return, or portions of a single expense allocated between the two.⁴ The fiduciary must file a waiver statement for any portion claimed on the income tax return, confirming it won’t also be taken on Form 706.⁵

The choice matters because the two deductions have different values. A deduction on Form 1041 reduces income taxed at up to 37%. The same deduction on Form 706 reduces the estate taxed at 40%. Running the numbers both ways before making the election is worth the effort.

Investment Advisory Fees

Investment management costs are treated more narrowly than administration expenses. Under Section 67(e), costs that an individual investor would also incur, such as standard portfolio management fees, were historically miscellaneous itemized deductions subject to a 2% floor. The Tax Cuts and Jobs Act suspended that deduction from 2018 through 2025, and subsequent legislation made the elimination permanent. Routine investment advisory fees are no longer deductible for estates and trusts.

Costs unique to trust or estate administration, things an individual investor simply wouldn’t pay, still qualify. If a trust pays a higher advisory fee because the advisor must balance competing interests between current and remainder beneficiaries, or must comply with specialized fiduciary investment standards, the incremental cost above what an individual would pay remains deductible.⁶ When an advisor charges a single bundled fee covering both investment management and trust administration, the fee must be allocated between the deductible and non-deductible portions.

Charitable Contributions

Estates and trusts get a better deal on charitable giving than individuals do. Under Section 642(c), the entity can deduct the full amount of gross income paid to a qualifying charity, with no percentage-of-income cap.⁵ The catch: the governing document, meaning the will or trust agreement, must specifically authorize charitable giving. If the document is silent, the deduction is unavailable no matter how worthy the cause.

A look-back election adds timing flexibility. If a charitable payment is made after the close of the tax year but before the last day of the following year, the fiduciary can elect to treat it as paid in the earlier year.⁵ The window is broader than the 65-day rule for distributions: the fiduciary has up to a full year after the close of the tax year to make the contribution and still apply it backward.

Deductible Taxes and Interest

Estates and trusts can deduct state and local income taxes and real property taxes paid on assets the entity holds. For 2026, the state and local tax (SALT) deduction cap stands at $40,000 for most filers, including non-grantor trusts, up from the $10,000 limit that applied from 2018 through 2024. The higher cap phases out for entities and individuals with modified adjusted gross income above $500,000 and drops back to $10,000 for income above $600,000. These thresholds increase by 1% per year through 2029.

Interest payments on debts owed by the entity also qualify in certain circumstances. The most common example is interest on federal estate taxes deferred under Section 6166, which allows estates consisting largely of closely held business interests to pay the tax in installments over several years.⁷ The interest paid during the deferral period reduces the entity’s income tax burden.

Capital Losses

Estates and trusts can deduct capital losses against capital gains just as individuals do. When losses exceed gains, the entity can deduct up to $3,000 of net capital loss against ordinary income each year.⁸ Unused losses carry forward to future tax years.

The more interesting rule involves termination. If an estate or trust still has capital loss carryovers when it closes out, those losses don’t vanish. They pass through to the beneficiaries who succeed to the entity’s property.⁹ The carryover keeps its character as long-term or short-term in the beneficiary’s hands, and the beneficiary’s first eligible tax year is the one in which or with which the entity terminates.

The Personal Exemption

Each estate or trust receives a small annual exemption that functions as an automatic deduction. The amounts are fixed by statute and are not adjusted for inflation:

Estates: $600 per year
Simple trusts (required to distribute all income currently): $300 per year
Complex trusts (all other trusts): $100 per year

The amounts won’t drive tax planning, but the fiduciary must apply the correct exemption when preparing the return.⁵

Distributions Also Help With the Net Investment Income Tax

On top of the regular income tax, estates and trusts may owe the 3.8% net investment income tax (NIIT) on the lesser of their net investment income or the excess of their adjusted gross income above the threshold for the highest tax bracket. For 2025, that threshold was $15,650.¹⁰ The 2026 figure is indexed for inflation and tracks the top bracket threshold.

Because the NIIT threshold is so low, almost any entity with meaningful investment income will owe it. Distributions to beneficiaries reduce the entity’s adjusted gross income and can push it below the threshold, so the income distribution deduction pulls double duty: regular income tax savings and NIIT relief. The 3.8% surtax is reported on Form 8960, attached to Form 1041.

Excess Deductions When the Entity Terminates

When an estate or trust wraps up and its final-year deductions exceed its gross income, the excess is not wasted. Under Section 642(h), it passes through to the beneficiaries who succeed to the entity’s property.¹¹ Each deduction retains its character in the beneficiary’s hands, so a non-miscellaneous itemized deduction stays a non-miscellaneous itemized deduction.

Beneficiaries can claim these excess deductions only in the tax year during which the entity terminates. There is no carryforward to a later year. The same principle applies to unused capital loss carryovers and net operating loss carryovers, which also transfer to beneficiaries on termination.⁹ The personal exemption and the charitable contribution deduction do not pass through; only administration expenses and other ordinary deductions qualify.

Timing matters. Closing an entity in a year when the primary beneficiary has little taxable income wastes the deduction. If the beneficiary expects a stronger income year ahead, waiting to terminate can turn an unused deduction into a real tax savings.
