Trusts, Estates, and Agency Accounts (NAICS 525920): An Investor's Primer

1. Overview

North American Industry Classification System (NAICS) code 525920 is one of the strangest "industries" in the federal statistical system: it is not a business you can buy, staff, or run for profit. The code covers the legal arrangements themselves — personal trusts, decedents' estates, bankruptcy estates, and agency accounts — that hold and pass on assets "on behalf of the beneficiaries under the terms of a trust agreement, will, or agency agreement." [1] A living trust set up to pass a family's assets to its children, the estate opened when someone dies, a special-needs trust, a South Dakota dynasty trust — each is a member of this "industry." Collectively they are the plumbing through which a large share of American household wealth is held, protected, and handed down.

Why any investor — public-market or private — should care: this is where an enormous pool of the country's private capital physically sits, and the flows through it are large and predictable. About 3.19 million fiduciary income-tax returns (Internal Revenue Service (IRS) Form 1041) are filed each year for estates and trusts. [2] The research firm Cerulli Associates projects that $124 trillion of wealth will change hands through 2048 as older generations die and give — the "great wealth transfer" — with most large transfers routed through trusts and estates. [3]

The key point for anyone sizing this up: you cannot own a trust as a security or a business. What is investable is the fiduciary-services franchise that administers these entities and earns fees on the assets inside them. Public-market investors reach it through trust banks, custodians, and wealth managers; private investors reach it through independent trust companies, private banks, family-office platforms, and registered investment advisers (RIAs). NAICS 525920 therefore maps the demand for fiduciary administration far better than it maps any set of companies.

2. What it is, and how it's structured

A trust is a legal arrangement in which one party (the trustee) holds legal title to assets for the benefit of others (the beneficiaries). An estate is the pool of assets left when a person dies, administered by an executor or administrator until it is distributed. An agency account is a simpler arrangement in which an agent holds and manages assets under specified instructions while the owner keeps legal title. NAICS 525920 is the container — the trust, estate, or account as a stand-alone legal entity. Census examples include bankruptcy estates, private estates, personal investment trusts, testamentary trusts, and settlement trust funds. [1]

Crucially, the code excludes the firms that do the work. In NAICS 2022 the Census Bureau classifies:

• Portfolio management and investment advice for these accounts in 523940, Portfolio Management and Investment Advice; [1]
• Trust, fiduciary, and custody activities — the trust departments, trust companies, and custodians that administer trusts and settle estates — in 523991, Trust, Fiduciary, and Custody Activities; [1]
• Estate-planning legal work in law offices (NAICS 5411); and
• A trust that actually operates a business (say, it owns a farm or a store) under whatever that business does.

So 525920 is the wealth itself; the money-making service industries around it live in adjacent codes. (Banking, custody, and securities-processing operations also appear in adjacent 522xxx and 523xxx industries.)

Ownership is unusual because these entities have no owners in the corporate sense — a trust is controlled by its trustee and exists for its beneficiaries. Trustees fall into a few broad camps: (a) individual trustees (a spouse, adult child, or friend); (b) bank and trust-company trustees (Northern Trust, Bank of America, Wilmington Trust, and others); (c) independent, non-depository trust companies chartered in trust-friendly states; (d) client-owned or mutual structures (for example, Vanguard's trust arm); and (e) law firms, RIAs, and court-appointed fiduciaries acting as trustee or administrative trustee. The investable opportunity is concentrated in camps (b) through (e).

3. How big it is (and why the usual federal figures miss it)

Standard business statistics essentially do not see this industry. Trusts and estates are legal entities that generally have no paid employees — administration is performed by outside fiduciaries counted under other NAICS codes. Two authoritative exclusions make this explicit: the Census Bureau's Statistics of U.S. Businesses (SUSB) program excludes NAICS 525920 outright, [5] and its Nonemployer Statistics program excludes the entire NAICS 525 sector (funds, trusts, and other financial vehicles). [6] As a result, there is no reliable federal establishment, employment, payroll, or revenue figure for this code, and no federal concentration ratio.

Our ground-truth federal file for 525920 contains only one industry-specific number: a Small Business Administration (SBA) size standard of $40 million in average annual receipts — the threshold below which one of these entities counts as "small" for federal purposes. [4] That is an eligibility line, not a measure of industry size. Treat any purported "number of establishments" or "employment" figure for this code with suspicion, and read the absence of a market-size figure as a coverage gap, not as evidence the activity is small.

Where the industry actually becomes visible is in tax and bank-regulatory data:

• Tax filings. About 3.19 million Form 1041 fiduciary returns are filed annually, and estates and trusts remit on the order of $74.6 billion a year in federal income tax (gross collections). [2] A trust owes federal income tax only on income it retains; income paid out to beneficiaries is taxed on their own returns — so these collections badly understate the income these entities actually generate.
• Assets at insured banks. At Federal Deposit Insurance Corporation (FDIC)-insured banks, personal trust and agency accounts held roughly $1.27 trillion at year-end 2024 (about $823 billion managed plus $452 billion non-managed). Those same banks reported about $6.5 trillion in total managed fiduciary assets, $29.9 trillion in non-managed fiduciary assets, and a further $138 trillion in custody and safekeeping. Roughly 1,438 banks hold fiduciary powers and about 1,052 actively exercise them. [7]
• Assets at non-bank trust banks. Separately, the Office of the Comptroller of the Currency (OCC) reports that the uninsured national trust banks it supervises held about $7.0 trillion in assets under administration at year-end 2025 (roughly $5.3 trillion fiduciary, $1.7 trillion custody). [8]
• The state-charter boom. South Dakota alone — a magnet for dynasty and asset-protection trusts — held about $815 billion in trust assets at year-end 2024 (up from roughly $104 billion in 2011) and topped $900 billion in 2025, spread across roughly 115 chartered trust companies. [9]

Even summed, these sources undercount the whole: trillions more sit in trusts run by individual trustees, RIAs, and non-bank trust companies that no single agency tallies. And company-reported "assets under custody/administration" are useful scale indicators for providers — they are not the size of NAICS 525920 and must not be added together. The honest summary: trusts and estates hold many trillions of dollars of U.S. private wealth, with the personal-trust slice at insured banks (~$1.3 trillion) the best-measured corner of a much larger, only-partly-counted whole. [7]

4. The investable universe

There is no pure public "trust and estate" stock, because the trusts themselves are not companies. Public-market investors own the theme through the fiduciaries — trust banks, custodian banks, and wealth managers whose fee income rises with trust, estate, and custody assets. None is a pure play on 525920; each carries a much larger surrounding business. Figures below are the providers' own reported scale, not the size of the industry.

Private and other owners of the fiduciary opportunity include:

• Independent, non-depository trust companies, many chartered in South Dakota, Nevada, Delaware, Wyoming, and Alaska.
• Private-wealth firms and partnerships: Bessemer Trust (a Delaware trust company owned chiefly through trusts), [21] Brown Brothers Harriman (a private partnership with trust affiliates), [20] Glenmede, Whittier Trust, and Pathstone.
• Client-owned platforms: Fidelity's Fidelity Personal Trust Company, a federal savings bank offering trustee, co-trustee, custody, tax, and distribution services; [18] and Vanguard National Trust Company, whose ultimate ownership runs to Vanguard's funds and their shareholders, supervised by the OCC. [19]
• Single-family private trust companies (PTCs), chartered by wealthy families to serve as their own trustee.
• RIAs partnering with "administrative trustee" platforms (for example, National Advisors Trust or Alta Trust) to offer trustee services without a bank charter — a segment private-equity firms are actively rolling up.

Private-company disclosure is far thinner than public reporting, so client retention, fee schedules, regulatory filings, and audited financials matter more when underwriting these owners.

5. How the money works

Two very different economic engines sit inside this code.

The trust or estate itself is a pass-through wealth vehicle, not a profit center. It holds a portfolio — stocks, bonds, cash, real estate, private interests — and earns investment income, which is either distributed to beneficiaries (and taxed on their returns) or retained (and taxed to the trust). Retained trust income is taxed on a brutally compressed schedule, reaching the top 37% federal bracket at only about $15,000–$16,000 of income, which is exactly why trustees usually distribute income and why tax collections understate the wealth involved. [2] For the family, the "return" here is simply the portfolio's performance, net of taxes and fees.

The fiduciary that administers it is where investors make money, and the metrics are those of an asset-based service business, not a lending or manufacturing one:

• Assets under administration/custody (AUA/AUC) and assets under management (AUM) are the top-line drivers. Most fees are charged as a percentage of assets, so revenue scales with account size and market levels — rising markets can lift revenue with no new mandates; falling markets cut it even when account counts hold steady.
• Fee rate (in basis points). A real-world anchor: FDIC-insured banks earned roughly $5.2 billion in personal-trust and agency fee income on about $1.27 trillion of personal-trust assets in 2024 — a blended rate near 41 basis points (0.41%) per year (author's calculation from FDIC data). [7] Managed (discretionary) accounts, where the fiduciary also invests the money, command materially higher fees than non-managed/directed/custody accounts, where it only administers — so the managed-vs-non-managed mix is a key margin lever.
• Other fee lines: custody, recordkeeping, tax reporting, distribution processing, and corporate-trust work (bond trustee, paying agent, escrow, securitization, loan agency).
• Net interest income ("float"). Bank fiduciaries also earn a spread on eligible uninvested cash — a rate-sensitive add-on — though fiduciary rules constrain self-dealing and govern funds awaiting investment or distribution. [22]
• Unit economics. Costs are mostly people (trust officers, portfolio managers), technology, and compliance, and are largely fixed — so incremental assets carry high operating leverage. Best of all, the revenue is recurring, sticky, and multi-generational: trusts can last decades (or, in perpetuity states, forever), and moving a trustee is slow and costly, so relationships behave like annuities.

The flip side: because fees are asset-based, revenue falls with markets, and the business faces steady fee compression from index investing and low-cost RIAs.

6. What drives demand

• The great wealth transfer. The single biggest tailwind. Cerulli projects $124 trillion moving to heirs and charity through 2048, with roughly $100 trillion from Baby Boomers and older households (about 81% of the total; ~$105 trillion to heirs and ~$18 trillion to charity). [3] Trusts and estates are the primary conduits.
• Demographics. An aging, affluent population means more estates opened and more trusts funded each year. The U.S. population age 65 and older reached 61.2 million (18.0% of the population) in 2024. [26]
• Estate- and gift-tax policy. The 2025 One Big Beautiful Bill Act (OBBBA) set the federal estate, gift, and generation-skipping transfer (GST) tax exemption at a permanent $15 million per person ($30 million per married couple) from January 1, 2026, indexed to inflation. [25] A high, stable exemption removes tax uncertainty and, going forward, shifts demand away from pure estate-tax avoidance and toward control, asset protection, privacy, governance, philanthropy, special-needs planning, and business succession — needs that persist regardless of the tax rate.
• Private and illiquid assets. Closely held businesses, real estate, private funds, mineral interests, and concentrated stock require far more specialized administration than a standard brokerage account. [20][21]
• State-law competition. States compete to host trusts. South Dakota, Nevada, Delaware, Wyoming, and Alaska offer no state income tax on trusts, strong asset protection, directed-trust flexibility, and (in some) no rule against perpetuities, enabling "dynasty" trusts that never end — pulling hundreds of billions into a handful of states. [9]
• Institutional and capital-markets activity. Debt issuance, employee-benefit plans, fund administration, escrow, bankruptcy, and settlement arrangements create recurring corporate-trustee and agency mandates. [1]
• Market levels and interest rates. Because fees are asset-based and float is rate-sensitive, rising equity markets and higher short-term rates both lift fiduciary revenue.

7. Regulation

Fiduciary activity is heavily regulated, but at the administrator level, not the trust level, through overlapping federal, state, court, and contractual regimes.

• National banks and national trust companies with fiduciary powers are governed by the OCC's Regulation 9 (12 CFR Part 9), which sets standards for pre-acceptance review, controls over fiduciary assets, conflict-of-interest policies, and periodic fiduciary audits. [22] An OCC final rule effective April 1, 2026 clarified that national banks limited to trust-company operations may conduct related non-fiduciary activities. [23] State-chartered trust companies are supervised by state banking departments; FDIC-supervised institutions face separate trust-power and examination requirements. [7]
• Reporting. Banks report fiduciary assets, accounts, and income on Schedule RC-T of their quarterly Call Reports, which the FDIC and OCC aggregate — the source of the asset figures in Section 3. [7][8]
• Fiduciary duty and prudent investing. Trustees owe strict duties of loyalty and prudence. Most states have enacted the Uniform Prudent Investor Act (portfolio-level risk management) and, in 36 states plus the District of Columbia, the Uniform Trust Code (UTC), which standardizes trust administration; state trust, probate, and tax law and the trust document ultimately set a fiduciary's practical duties. [24]
• Investment advisers and custody. Advisers with custody of client assets must meet the Securities and Exchange Commission (SEC) custody rule, including use of qualified custodians. [28]
• Retirement plans. Employee-benefit trust fiduciaries must comply with the Employee Retirement Income Security Act (ERISA). [29]
• Anti-money-laundering. Banks and covered institutions must run anti-money-laundering (AML) and customer-due-diligence (CDD) programs; Financial Crimes Enforcement Network (FinCEN) guidance specifically addresses trusts, trustees, source of wealth, and account control. [27]
• Tax. Trusts and estates file Form 1041; the estate, gift, and GST taxes are administered by the IRS. [2][25]

Regulation is therefore both a barrier to entry and a continuing cost of operation.

8. Competitive dynamics and consolidation

The custody end is a scale oligopoly — BNY, State Street, JPMorgan, and Northern Trust dominate tens of trillions in institutional custody. [11][12] Personal trust, by contrast, is fragmented across national banks, regional bank trust departments, independent trust companies, RIAs, family offices, and court-appointed fiduciaries. Durable competitive advantages include trust-company charters and multistate capability, long fiduciary track records, clean account/tax/beneficiary data, reliable technology and cybersecurity, the ability to administer unusual or alternative assets, and integrated relationships with attorneys, accountants, and advisers.

Consolidation runs along several lines:

• Bank and trust-company M&A keeps absorbing fiduciary franchises — M&T owns Wilmington Trust; [16] WSFS owns Bryn Mawr Trust; UMB expanded its wealth platform via the Heartland Financial acquisition that closed January 31, 2025. [17]
• State-charter migration. Assets keep flowing to South Dakota, Nevada, and Delaware trust companies, pressuring high-tax-state incumbents. [9]
• RIA convergence. RIAs are moving into trustee services via administrative-trustee platforms, chipping at banks' traditional lock on the trustee role — and private equity is rolling up RIAs at pace.
• Technology. Digital estate-planning and trust-accounting tools lower the cost to create and run trusts, expanding the market downmarket while squeezing fees.

A live example of scale-seeking: in mid-2025 there was press reporting of a possible BNY–Northern Trust combination; Northern Trust publicly affirmed its intent to remain independent. [30] Whether or not that specific deal happens, the direction of travel is toward fewer, larger fiduciary platforms — though regulation, systems conversion, cultural integration, and fiduciary liability make trust-book mergers harder than simply combining account balances.

9. Risks

• Market risk. Asset-based fees fall when markets fall; a bear market cuts fiduciary revenue with no change in workload.
• Fee compression. Index funds and low-cost RIAs continue to pull down the basis-point fees fiduciaries can charge, especially for routine administration.
• Fiduciary liability and conflicts. Trustees can be surcharged (held financially liable) for imprudent investing, distribution errors, tax mistakes, or breaches of duty; self-dealing, proprietary products, and cash-management decisions can trigger long-tail litigation and enforcement.
• Operational and cyber risk. A single payment, valuation, recordkeeping, or identity error can affect many beneficiaries at once.
• Policy reversal. The $15 million exemption is "permanent" only until Congress changes it; a future cut would raise estate-tax-driven demand, while the current high level shifts demand toward non-tax motives. [25]
• Aging client base and talent. Legacy trust books skew old; assets can leave when trusts terminate and distribute, and experienced trust officers are retiring faster than they are replaced (key-person risk at smaller firms).
• Rate sensitivity. Deposit "float" income falls when short-term rates decline.
• Regulatory and reputational. AML scrutiny of secrecy-friendly trust states and periodic political attention to "billionaire" dynasty trusts are ongoing overhangs.
• Bank-parent and private-market risk. Public investors in a trust bank also own its credit, liquidity, interest-rate, and capital risk — trust earnings do not insulate the parent. Private trust-company stakes may offer sticky recurring revenue but come with thin disclosure, illiquid ownership, and heavy regulatory-approval requirements.

10. How to invest, and the outlook

Public routes. Buy the fiduciaries, not the trusts. The cleanest listed exposure is Northern Trust (NTRS), the closest thing to a pure trust-and-wealth bank; the custodian giants BNY (BK) and State Street (STT); and the wealth/trust arms embedded in the big banks — JPMorgan (JPM), Bank of America (BAC) (leading managed personal-trust provider), Wells Fargo (WFC), U.S. Bancorp (USB), M&T (MTB) (Wilmington Trust), plus regionals such as PNC, Truist, Comerica, Fifth Third, and Regions. For trust brands inside larger firms, Franklin Resources (BEN) owns Fiduciary Trust, WSFS (WSFS) owns Bryn Mawr Trust, and UMB Financial (UMBF) runs a broad personal- and corporate-trust platform. When evaluating these names, watch fee-based revenue growth, AUC/A and AUM net flows, the managed-vs-non-managed mix, operating leverage, and pretax margins in the wealth/trust segment — not just the overall bank — and apply share-price valuation only after separating recurring fee earnings from cyclical market swings and one-time gains.

Private routes. There is no way to "own a trust," but private-market exposure to the fiduciary economy runs through equity stakes in independent trust companies and RIA/wealth platforms, backing technology-enabled trust-accounting or fiduciary-services roll-ups, providing private credit to platforms with recurring fee revenue, or acquiring niche providers (charitable, bankruptcy, estate, or alternative-asset administration). Underwrite the operating company, not the client assets — AUC/A can be enormous while the provider's actual fee revenue and enterprise value stay modest. Wealthy families can effectively "invest" by chartering a single-family private trust company to serve as their own trustee, capturing economics and control that would otherwise go to an outside institution.

Outlook. The structural demand picture is unusually strong: a multi-decade, $124 trillion wealth transfer, an aging affluent population, growing complexity in private and illiquid assets, and a newly permanent $15 million exemption that keeps planning activity high while shifting it toward durable non-tax motives. [3][25] The likely winners are scaled, technology-enabled fiduciaries — those pairing fiduciary credibility with low-cost technology, strong cybersecurity, open investment architecture, and skill with difficult assets — and the trust-friendly states that keep attracting charters. [9] The principal swing factors are market levels (which move asset-based fees directly), the pace of fee compression from RIAs and indexing, and further consolidation among the large custody and trust banks. On balance, the fiduciary-services layer around trusts and estates is a durable, high-margin, annuity-like business riding one of the largest wealth transfers in history — attractive for its stickiness, but cyclical with markets and grinding against long-run fee pressure. The largest risk to the thesis is not that trusts disappear; it is fee compression or a major operational failure that erodes client trust.
