Are Investment Advisory Fees Deductible On A Trust Return? | Clear Tax Rules

No, standard investment advisory fees for most U.S. trusts are not deductible under current Form 1041 rules, except for narrow trust-only charges.

If you manage a trust, investment advisory fees can feel like a big line item. The tax rules around those fees changed after recent U.S. tax law updates, and the result catches many trustees off guard. On a trust return, some costs still reduce taxable income, while others vanished for a stretch of years.

This guide walks through how trust expense deductions work, what changed under section 67(g) of the Internal Revenue Code, and when investment advisory fees may still help on a Form 1041 filing. The focus here is U.S. federal income tax for estates and non-grantor trusts; state rules or cross-border situations can differ a lot.

None of this is personal tax or legal advice. Use it as a roadmap for better questions when you work with a qualified professional or your fiduciary team.

How Trust Tax Rules Categorize Expenses

The starting point is how a trust return, Form 1041, groups income and deductions. A trust reports interest, dividends, rents, capital gains, and other items, then subtracts allowed deductions to arrive at taxable income.

The IRS explains this layout in the official Instructions for Form 1041, which outline where each category of income and expense belongs on the return and how amounts feed into Schedule K-1 for beneficiaries.

Form 1041 And The Role Of Deductions

Every deduction on a trust return tends to fall into one of three buckets:

• Plain administrative costs like trustee fees, tax prep costs, and legal work tied to trust administration.
• Investment-related costs such as brokerage commissions or advisory fees for managing a portfolio.
• Other itemized-style costs such as certain taxes or miscellaneous fees.

Section 67 of the Internal Revenue Code sets out a special rule for estates and non-grantor trusts. Under section 67(e), expenses that only arise because the assets sit inside a trust or estate can be deducted in full when computing adjusted gross income for the entity. The Treasury regulations confirm that this group of “section 67(e)” deductions is not treated as miscellaneous itemized deductions and does not get blocked by section 67(g) during the 2018–2025 period.

Regulation section 1.67-4 states that these section 67(e) deductions are not itemized and are not miscellaneous itemized deductions, so the section 67(g) suspension does not apply to them.26 CFR § 1.67-4 draws that line and then divides other costs into a second group that would have fallen under the former 2% floor.

Types Of Trusts And Who Really Bears The Fees

Before deciding whether a fee is deductible on a trust return, you need to know which type of trust you have for income tax purposes:

• Non-grantor trusts are separate taxpayers and file their own Form 1041. Deductions here directly affect trust-level tax and the amounts that flow through to beneficiaries.
• Grantor trusts usually do not claim these deductions on Form 1041 at all. The grantor reports income and related expenses on a personal Form 1040 instead.

Most questions around “Are investment advisory fees deductible on a trust return?” center on non-grantor trusts, since that is where Form 1041 actually carries the tax burden.

Are Investment Advisory Fees Deductible On A Trust Return? Core Rules Today

Under older law, investment advisory fees for a trust were treated like similar fees for an individual. They were miscellaneous itemized deductions subject to a 2% of adjusted gross income floor. The Supreme Court in Knight v. Commissioner held that ordinary investment advisory fees are the kind of costs that individuals also pay, so they do not qualify as special trust-only expenses and fall under that 2% rule.

The Tax Cuts and Jobs Act (TCJA) added section 67(g). That section suspends all miscellaneous itemized deductions for tax years beginning after December 31, 2017 and before January 1, 2026. The IRS later issued final regulations, known as TD 9918, to clarify how this plays out for trusts and estates. The regulations confirm that true administration costs under section 67(e) remain deductible for estates and non-grantor trusts during these years, while miscellaneous itemized deductions remain suspended.

The Federal Register summary of these regulations explains that costs paid or incurred in the administration of an estate or non-grantor trust and allowed under section 67(e) are not miscellaneous itemized deductions and are not disallowed by section 67(g).Effect of Section 67(g) on Trusts and Estates sets out that list.

Ordinary investment advisory fees do not fall into that protected category. They sit in the same basket as they did before TCJA: expenses for the production of income that would have been subject to the 2% floor, now simply suspended for 2018–2025. So for those years, a non-grantor trust generally cannot deduct standard portfolio advisory fees as a separate line on Form 1041.

Why Investment Advisory Fees Land In The Suspended Bucket

The Knight case is the main reason investment advisory fees sit in this less favorable bucket. In that case, the trustee hired an outside advisor and tried to deduct the entire fee without the 2% floor. The Court held that because individuals routinely pay for investment advice, the cost is not “unique” to trust administration. Only a portion that would exist solely because the property sits in a trust might fall into the protected section 67(e) category.

That reasoning carries through to the post-TCJA regulations. The IRS and Treasury repeated that expenses described in section 67(e) remain deductible, while other costs still count as miscellaneous itemized deductions that section 67(g) suspends for a block of tax years. The Journal of Accountancy gives a plain-language summary in its piece on trust and estate expense deductions under TD 9918, which tracks the same division of expenses.

This means that for calendar years 2018 through 2025 a non-grantor trust usually gets:

• A deduction for administration expenses that only arise because assets sit in a trust or estate.
• No deduction for standard investment advisory fees that look the same as fees an individual investor would pay.

Later tax years could see a change if Congress modifies section 67(g) again or lets the suspension expire, so trustees need to watch current law when they prepare each return.

Common Trust Expenses And How Deductibility Works

Investment advisory fees are easier to sort out when you see them beside other typical trust costs. The table below pulls together a high-level view for non-grantor trusts under current U.S. rules, based on section 67(e), section 67(g), and the IRS regulations that followed TCJA.

Expense Type	Deductible For Non-Grantor Trust?	Notes / Conditions
Trustee fees	Yes, as administration expenses	Compensation for fiduciary duties such as record-keeping, investment oversight, and distributions generally falls under section 67(e).
Tax preparation for Form 1041	Yes	Fees for preparing the fiduciary income tax return are classic administration costs and remain deductible during the 2018–2025 suspension period.
Legal fees for trust administration	Yes, if tied to administration	Work related to interpreting the document, court accountings, or required filings usually qualifies; personal or beneficiary-level work does not.
Appraisal fees for trust-level needs	Yes, in many cases	Appraisals to value assets for required filings can fall inside section 67(e); purely personal appraisals for a beneficiary do not.
Standard investment advisory fees	No for 2018–2025	Treated as the same type of expense an individual would pay; classified as miscellaneous itemized deductions suspended by section 67(g).
Bundled fiduciary fee (trustee + advisory)	Partly	Regulations call for a reasonable allocation between administration services (deductible) and investment advisory services (suspended for 2018–2025).
State and local income taxes of the trust	Yes, subject to current limits	Still deductible for the trust, though different from the individual SALT cap picture for Form 1040 filers.
Safe-deposit box for trust records	Often yes	Costs mainly tied to safeguarding trust documents and assets tend to align with administration expenses under section 67(e).
Investment-related travel or research costs	Generally no	Viewed as investment expenses similar to those of an individual investor; fall under suspended miscellaneous itemized deductions.

Investment Advisory Fees On Trust Returns: When Deductions Still Exist

Even during the 2018–2025 suspension period, not every dollar paid to a firm with “investment” in its name lands in the non-deductible category. Structure matters, invoices matter, and the real work performed matters.

Bundled Fiduciary Fees And Allocation

Many corporate fiduciaries charge a single “bundled” fee that covers trustee work, portfolio management, and other services. Earlier IRS guidance on bundled fees explained that trustees must make a reasonable internal split. The portion linked to fiduciary work stays deductible as an administration expense, while the investment advisory slice follows the miscellaneous itemized deduction rules and sits on the sideline for 2018–2025.

Under the current regulations, a trust that pays a bundled fee should:

• Keep engagement letters and fee schedules that spell out the parts of the service.
• Apply a rational method to split the fee between administration and investment work.
• Document that method in the trust’s permanent file in case questions arise later.

The regulations under section 1.67-4 confirm that this sort of allocation remains part of the system and that only the administration slice lands in the section 67(e) bucket.

Trust-Only Investment Services

Some costs that look investment-related at first may exist only because the assets sit inside a trust. Examples include special reviews needed because there are multiple beneficiaries with different income and remainder interests, or reports prepared solely to meet fiduciary accounting standards that would not apply to an individual owner.

If a fee truly arises only because property sits inside a trust, and would not exist in the same way for a regular individual investor, it may fall under section 67(e) and remain deductible. That is a facts-and-circumstances question. Trustees often rely on detailed billing statements and written service descriptions to show which activities qualify.

Grantor Trusts And Who Claims The Deduction

When a trust is treated as a grantor trust for income tax purposes, the landscape changes again. In many cases the grantor, not the trust, reports income, deductions, and credits on a personal Form 1040. Investment advisory fees paid for that trust then follow the same treatment as other individual investment expenses. Under current law those personal investment expenses are suspended as miscellaneous itemized deductions through the 2018–2025 period.

The result: even if a grantor trust pays investment advisory fees directly from trust assets, the tax effect usually lands on the grantor’s return and carries the same limits as any other investment expense that an individual pays.

Practical Steps For Trustees Handling Investment Advisory Fees

Trustees rarely have time to read regulations in detail. A short process helps keep investment advisory fees in the right place on the return and reduces the chance of amending later.

Step 1: Confirm The Tax Year And Trust Type

Start by checking whether the trust is non-grantor or grantor for income tax purposes. The trust instrument, prior returns, and your tax advisor’s past memos give clues here. Then look at the tax year in question. For calendar years starting in 2018 through 2025, the section 67(g) suspension applies; earlier years and later years follow different rules.

The Form 1041 instructions list which schedules and lines carry deductions for trust-level expenses and note which sections of the Code drive those entries. Reading the instructions side by side with your fee schedule can clear up many classification issues.

Step 2: Map Every Fee To A Category

Trust accounting records often have one line for “investment fees” and another for “trustee fees.” For tax purposes, that high-level split is not enough. A better approach:

• List each invoice paid to advisors, custodians, and professional firms.
• Mark which services relate only to trust administration, which relate only to investment advice, and which cover both.
• For blended services, assign a reasonable percentage to each side, based on time records or fee schedules where possible.

That mapping lets you identify which dollars may qualify under section 67(e) and which dollars fall into the suspended miscellaneous itemized deduction category for the current period.

Step 3: Reflect The Split On Form 1041

Once you have that breakdown, carry it into the return. Administration expenses usually appear as deductions on the main body of Form 1041, while investment items that count as suspended miscellaneous itemized deductions simply drop out for 2018–2025 tax years.

The final regulations under section 67(g), described in detail in the Federal Register notice on Effect of Section 67(g) on Trusts and Estates, reinforce that section 67(e) expenses continue to reduce adjusted gross income for the trust and remain outside the suspended category.

Investment Advisory Fee Deductions By Scenario

The treatment of investment advisory fees shifts with time periods and structures. The table below gives a simplified view of common setups and how those fees tend to land on a U.S. federal Form 1041 filing.

Scenario	Deductible On Form 1041?	Typical Reporting
Non-grantor trust in 2017 or earlier, separate advisory fee	Maybe, subject to 2% AGI floor	Investment advisory fees treated as miscellaneous itemized deductions; deduction allowed only to the extent above 2% of trust AGI.
Non-grantor trust in 2018–2025, separate advisory fee	No	Fee falls under suspended miscellaneous itemized deductions; no current deduction at the trust level under section 67(g).
Non-grantor trust with bundled trustee and advisory fee	Partly	Trust allocates the fee; administration slice deducted as a section 67(e) cost, advisory slice treated as suspended during 2018–2025.
Grantor trust where grantor reports all income	Not on Form 1041	Fees treated as expenses of the grantor; for 2018–2025, personal investment advisory fees are also suspended as miscellaneous itemized deductions.
Trust termination with excess deductions	Depends on type of cost	Section 67(e) expenses in excess deductions can carry out to beneficiaries; investment advisory portions remain in the suspended category for 2018–2025.

Planning Ideas And Common Pitfalls

Trustees still have room to manage overall tax cost, even with the current suspension of miscellaneous itemized deductions. A few practical patterns show up in many trust administrations.

First, fee structure matters. Where a bank or trust company offers a menu of services, a single blended fee that genuinely covers administrative work and investment oversight may lead to a larger section 67(e) share than separate a-la-carte bills. That only works if the documents and billing accurately reflect the split and the trust truly receives both services.

Second, record-keeping makes a big difference. Short, vague invoices that just say “investment services” for the entire fee make it hard to support any deduction beyond obvious trustee compensation. Detailed descriptions tied to specific duties, especially duties that only a fiduciary would perform, give your tax preparer better footing when classifying costs.

Third, pay attention to who is legally responsible for the fee. In a grantor trust setting, moving a fee from the personal level into the trust or the other way around often does not change the end result during the 2018–2025 suspension period, since both sides face similar limits on investment expenses.

Finally, revisit this topic once tax law for years after 2025 settles. Congress may extend, shorten, or reshape the suspension of miscellaneous itemized deductions. When that happens, the border between deductible and non-deductible investment advisory fees for trusts could move again.

When To Bring In A Tax Professional

Trust taxation blends statute, regulations, court cases, and long-standing IRS practice. The Knight case, the section 67(g) suspension, and the TD 9918 regulations all show how quickly the picture can change and how narrow the line is between administration expenses and investment expenses.

You may want direct help from a fiduciary tax specialist when:

• The trust pays large investment advisory fees that are bundled with trustee services.
• Multiple trusts with different grantors and beneficiaries share an advisor and split fees.
• The trust is winding down, and you need to sort out excess deductions and how they pass to beneficiaries.
• State tax rules differ sharply from the federal treatment, so a deduction lost at the federal level may still matter locally.

A short meeting with a professional who works with Form 1041 on a regular basis can prevent expensive filing errors and save time when the IRS or a beneficiary asks how you handled investment advisory fees on the return.

This article gives a general picture based on current federal rules and public guidance. Always review the latest IRS instructions and regulations and work with a qualified advisor who can apply those rules to the specific trust you manage.
