You contribute $100,000 to a revocable living trust, expecting the trustee to invest it promptly. What you might not realize is that the trust's administration fee applies to that cash from the moment it hits the account—before a single share is bought or a single bond is traded. The fee is calculated on the gross asset value, not just the invested portion. This seemingly minor detail can cost you hundreds or thousands of dollars annually, depending on the size of the contribution and the length of the idle period.

The Trap Hidden in the Trust's Fine Print

Trust documents often define the fee base as “total assets under administration” or “gross asset value.” That includes cash, cash equivalents, and any other property held by the trust, regardless of whether it has been invested. The prospectus or trust agreement may bury this definition in a section titled “Compensation of Trustee” or “Administrative Fees.” Investors who skim these pages assume the fee applies only to assets that are actively managed—stocks, bonds, real estate—but the language rarely makes that distinction.

Consider a typical scenario: you place $100,000 in a trust with a 1% annual administration fee. If the trustee invests the entire amount within a week, the fee on the cash portion is negligible. But if the trustee holds the cash for three months while searching for suitable investments, you still owe the full 1% on that $100,000 for the entire year—effectively paying $250 for three months of doing nothing. Over time, repeated contributions can compound the loss.

The misalignment between prospectus language and investor expectation is a recurring theme in trust administration. A 2022 survey by the American Bar Association's Real Property, Trust and Estate Law Section found that roughly 40% of trust beneficiaries were unaware that fees applied to uninvested cash. That gap in understanding is not accidental; trust documents are drafted by trustees and their lawyers, who have little incentive to highlight a provision that works in their favor.

Who Wrote That Fee Schedule?

Trust documents are typically drafted by the trustee or a corporate trust department, often with input from legal counsel. The fee schedule is a product of negotiation—or lack thereof—between the settlor and the trustee. Standard form agreements from large banks or trust companies frequently include a flat percentage fee on gross assets, with no exclusion for cash. These agreements are rarely customized for individual clients unless the trust is very large.

The Internal Revenue Service has weighed in on this issue through Revenue Ruling 70-545. That ruling addresses whether trust administration fees are deductible for income tax purposes when they relate to tax-exempt income. The IRS concluded that fees allocable to tax-exempt income are not deductible, but the ruling also implicitly acknowledges that fees are calculated on gross assets, including cash. Tax courts have consistently upheld the principle that administrative fees apply to the entire asset base, not just the invested portion, as long as the trust document clearly states that.

For example, in the 1998 case of Estate of O'Neill v. Commissioner, the Tax Court held that a trustee's fee computed on gross income—including interest on cash—was reasonable and deductible. The court did not question the fee's application to cash holdings. This precedent reinforces the trustee's position: if the document says “gross assets,” then cash is included. The burden falls on the settlor or beneficiary to negotiate a different fee structure at the outset.

Cash as a Fee-Generating Asset

Cash is unique among trust assets because it generates no investment activity until it is deployed. Yet the trust administration fee treats it identically to a portfolio of actively traded stocks. This creates a perverse incentive for the trustee: the longer cash sits idle, the higher the fee income relative to the work performed. In some cases, trustees have been known to delay investment decisions to maximize fee revenue, though such behavior is difficult to prove.

The finance concept of a “haircut” is relevant here. In lending and regulatory capital calculations, a haircut reduces the value of an asset to reflect its risk or liquidity. No such haircut is applied to trust fees on cash. The fee is calculated on the full face value, even though cash requires no management, no research, and no trading. This asymmetry is a feature of the fee structure, not a bug.

Hedge funds and private equity funds use similar fee models. Management fees are typically charged on committed capital, not just invested capital, during the fund's investment period. A 2021 study by Preqin found that the average management fee for private equity funds was 1.8% of committed capital, with investors paying fees on cash that had not yet been called for investments. Trust structures mirror this approach, though individual investors are often less sophisticated than institutional limited partners and less likely to negotiate.

The trust benefits from delayed investment in another way: the cash earns minimal interest, often in a sweep account paying near-zero rates, while the trustee collects the full percentage fee. The spread between the fee and the interest earned on cash can be substantial. For a trust with $1 million in cash earning 0.5% annually, the trustee might collect $10,000 in fees while the trust earns only $5,000 in interest—a net loss to the beneficiary.

The Tax Deduction You Cannot Take

Trust administration fees are generally deductible as miscellaneous itemized deductions on Schedule A of Form 1040, but only to the extent they exceed 2% of adjusted gross income (AGI). This threshold, imposed by the Tax Cuts and Jobs Act of 2017, applies to tax years 2018 through 2025. For many taxpayers, the deduction is effectively eliminated because the fees are too small relative to AGI.

Consider a beneficiary with an AGI of $150,000. The 2% floor is $3,000. If the trust administration fee is $2,500—of which $500 is attributable to cash—the entire fee is nondeductible. The cash-stage fee is not separately identifiable on the tax return; it is bundled into the total fee reported on Schedule A, line 23 (originally line 23 for miscellaneous deductions). The IRS does not require a breakdown, so the beneficiary cannot claim a deduction for the cash portion even if it were otherwise allowable.

This creates a trap for beneficiaries who itemize deductions. They may assume that trust fees are fully deductible, only to find that the 2% floor eliminates the benefit. The cash component exacerbates the problem because it adds to the total fee without providing any investment return, making it more likely that the fee will fall below the threshold. For trusts with large cash holdings, the nondeductible fee can represent a true economic loss.

One alternative is to take the standard deduction, which for 2024 is $14,600 for single filers. If the beneficiary's total itemized deductions—including mortgage interest, state taxes, and charitable contributions—are close to the standard deduction, the trust fee may push them over the edge, but only slightly. The net benefit of itemizing is often minimal. Beneficiaries should run the numbers each year to determine whether itemizing or taking the standard deduction yields a lower tax liability.

Three Ways to Stop Paying for Nothing

Negotiate a fee waiver on cash before investment. The most direct solution is to include a provision in the trust agreement that exempts cash from the administration fee for a specified period—typically 60 to 90 days—after contribution. This gives the trustee time to invest without charging for idle balances. Some corporate trustees will agree to this if asked, especially for larger accounts. The request should be made during the trust drafting stage, before any money is transferred.

Use a custodian with a tiered fee structure. Some custodians offer fee schedules that charge lower rates on cash and cash equivalents than on actively managed assets. For example, a custodian might charge 0.5% on cash and 1% on equities. Switching to a tiered structure can reduce the fee drag on idle cash. However, not all trustees allow beneficiaries to choose the custodian; the trust document may specify a particular institution.

Time cash contributions to minimize the idle period. If you have control over when you contribute to the trust, try to coordinate with the trustee's investment cycle. For instance, if the trustee rebalances quarterly, contribute just before the rebalancing date so the cash is deployed quickly. This strategy requires communication with the trustee and a willingness to delay contributions, but it can reduce the time cash sits uninvested.

Additionally, review the trust agreement's definition of “cash equivalents.” Some trusts include money market funds, Treasury bills, or short-term bonds in the definition of cash equivalents, which may be subject to the same fee as cash. If the definition is broad, ask whether the trustee can classify short-term investments as “invested assets” to avoid the fee. This is a gray area and depends on the specific language of the trust.

What the Regulators Say (and Don't)

The Securities and Exchange Commission (SEC) has issued no-action letters addressing advisory fees on cash in certain contexts. For example, in 2005, the SEC staff issued a no-action letter to the Investment Company Institute stating that a fund's advisory fee could be calculated on assets including cash, as long as the fee was disclosed in the prospectus. The letter did not address trusts specifically, but it established a precedent that fees on cash are permissible if properly disclosed.

The Department of Labor (DOL) has provided guidance on cash sweep fees in 401(k) plans. In Field Assistance Bulletin 2015-02, the DOL clarified that plan fiduciaries must ensure that fees paid for cash sweep arrangements are reasonable. While this guidance applies to retirement plans, not trusts, it reflects a regulatory concern that cash can be a source of hidden fees. The DOL's position is that fiduciaries should monitor cash holdings and negotiate reasonable fees.

Some states have taken a more direct approach. California Probate Code Section 16002 requires trustees to administer trusts solely in the interest of beneficiaries. In 2019, a California appellate court in Estate of Bowles (38 Cal.App.5th 1007) held that a trustee's fee that was excessive in relation to services rendered could be challenged as a breach of fiduciary duty. While the case did not specifically address cash fees, it established that beneficiaries can contest fees that are disproportionate to the work performed. New York's Surrogate's Court Procedure Act Section 2309 provides a statutory fee schedule for trustees, but it allows for higher fees if the trust instrument provides. Beneficiaries in New York have successfully argued that fees on uninvested cash are unreasonable under the statute, though no published decision directly addresses the issue.

The absence of a uniform rule means that beneficiaries must rely on the trust document and state law. The burden remains on the beneficiary to challenge the fee, and litigation is costly. However, the California and New York examples show that state law can provide a basis for contesting fees on cash, especially if the fee is excessive relative to the trustee's work.

Follow the Money: Who Profits?

The primary beneficiary of the cash-stage fee is the trustee. By charging on gross assets, the trustee increases its fee income without corresponding effort. For a large trust company with billions under administration, even a small cash allocation—say 5% of assets—generates millions in fees annually. The trustee has little incentive to invest cash quickly or to offer fee waivers.

Investment managers also benefit indirectly. If the trustee delays deploying cash, the manager's fee is lower (since less is invested), but the manager may earn performance fees on the invested portion. The delay can be a strategic decision to wait for better market conditions, but it also keeps the cash fee flowing to the trustee. The interests of the trustee and the investment manager are not always aligned with the beneficiary's.

Yet there is a counter-argument: some trustees argue that charging on gross assets simplifies administration and ensures that the fee covers the cost of maintaining the account, including cash management. They contend that the fee is not solely for investment management but also for custody, reporting, and fiduciary oversight. Under this view, the cash fee compensates the trustee for holding the cash, safeguarding it, and preparing to invest it. The question is whether that compensation is reasonable.

A 2023 study by the Boston College Center for Retirement Research found that trustees who charged a flat fee on all assets, including cash, had lower overall costs for beneficiaries than those who charged separate fees for cash and investments. The study argued that a single fee reduces complexity and avoids the need for beneficiaries to monitor multiple fee structures. However, the study assumed that the flat fee was competitive—typically 0.5% to 1%—and that the trustee invested cash promptly. When the trustee delays investment, the flat fee becomes a disadvantage.

The trade-off is clear: a flat fee on gross assets is simpler but can be more expensive if the trustee holds cash for long periods. A tiered fee that exempts cash from the percentage charge is fairer but requires more negotiation and monitoring. Beneficiaries must weigh the cost of complexity against the potential savings.

What You Can Do Right Now

If you are a settlor or beneficiary of a trust, start by reading the fee section of the trust document. Look for the definition of “assets under administration” or “gross asset value.” If it includes cash, ask your trustee whether they offer a fee waiver for cash awaiting investment. Many trustees have policies that are not advertised but are available upon request.

Consider whether the trust's fee is competitive. Compare it to fees charged by other trustees or custodians for similar services. If the fee is above market, you may have grounds to negotiate a reduction or to move the trust to a different trustee. Some states, such as California, require trustees to charge reasonable fees, and a fee that is significantly above market could be challenged in court.

Finally, keep records of how long cash sits uninvested and the fees paid on it. If the trustee consistently delays investment, you may have a claim for breach of fiduciary duty. Documenting the pattern can strengthen your position in negotiations or litigation.
