There is no balance that turns this on. The trigger I have watched actually work is a count: entities, tax jurisdictions, signers, counterparties, and people with a claim on the outcome. Families ask about size because size is easy to check. The number that decides it is what the household already spends on fragmented professional fees and on hours the founder never bills anyone.
Part of our guide: Family Office.
The short version
- The rule contains no asset test. The family office exclusion at 17 CFR 275.202(a)(11)(G)-1 turns on who you serve, who owns the office, and what you say in public.
- Count six things: entities that file, tax jurisdictions, signers who can move value, counterparties holding assets, professionals billing separately, and people with a claim on the outcome.
- The workload multiplies rather than adds. Four entities across six counterparties, closed monthly, is 288 account reconciliations a year.
- Price the status quo first. Twelve months of invoices plus the founder’s own unbilled hours is the comparison that decides this.
- Deductibility turns on section 162 against section 212. 26 U.S.C. § 67(h) disallows miscellaneous itemized deductions and, since the 2025 amendment, no longer expires.
Count the moving parts, then do the multiplication
The question arrives as a balance and answers as an org chart. The work comes from the number of independent things that have to agree with each other at the close of every period.
Six counts, on one page:
- Entities that file anything: LLCs, trusts, a foundation, a fund vehicle, anything organized abroad.
- Tax jurisdictions carrying a return or an information filing.
- Signers who can move value, plus the quorum required at each place.
- Counterparties holding assets or extending credit: custodians, exchanges, banks, lenders, desks, staking providers.
- Professionals billing separately who never read each other’s work.
- Claimants: beneficiaries, a former spouse, co-founders, charitable remaindermen, anyone owed an answer you must support with evidence.
Multiply the first four instead of adding them. Four entities holding assets at six counterparties, closed monthly, is 288 account reconciliations a year before anyone values a token. Add a jurisdiction and the filings multiply against the entities. Add a signer and every authority matrix, custodian record and governance document needs revising at once.
That product is what a family office absorbs. The households I see needing one are those where the product grew while the balance stayed modest: three trusts, two operating entities, positions in four states, coins at two custodians and a desk, and a brother-in-law on a signing quorum.
What the function already costs, including the part nobody invoices
Price what a family office would replace before pricing the family office. Twelve months of invoices: attorney, CPA, bookkeeper, tax software, custodian fees, valuation work, and whatever gets billed when a transaction has to be documented in a hurry. Then the founder’s own hours as the integration layer between all of them, at a rate you would pay a stranger. The second figure usually exceeds the first and never appears on a statement.
Two tax points move that arithmetic. Costs of managing investments fall under 26 U.S.C. § 212, and for an individual those are miscellaneous itemized deductions, which § 67(h) disallows outright for tax years beginning after 2017. The 2025 amendment deleted that provision’s end date and moved it from § 67(g), so anything written earlier cites the old letter. Costs of carrying on a trade or business under § 162 are treated differently, and the Tax Court applied that distinction to a family office in Lender Management, LLC v. Commissioner, T.C. Memo. 2017-246. Whether your facts reach that result is a question for your CPA.
Trusts sit differently again. 26 CFR § 1.67-4 lets administration costs that would not have arisen but for the property being held in trust reach adjusted gross income, so the suspension leaves those alone, while Knight v. Commissioner, 552 U.S. 181 (2008), put ordinary investment advisory fees generally outside that carve-out.
The line that separates a family office from a business that has to register
Congress replaced the exemption family offices had relied on with an exclusion the SEC had to define. 15 U.S.C. § 80b-2(a)(11)(G) leaves “family office” to Commission rule, and the SEC wrote it in June 2011 (Release No. IA-3220, 76 FR 37983, effective 29 August 2011). Notice what is absent from the operative paragraph:
“A family office is a company … that: (1) Has no clients other than family clients … (2) Is wholly owned by family clients and is exclusively controlled (directly or indirectly) by one or more family members and/or family entities; and (3) Does not hold itself out to the public as an investment adviser.”
The rule is generous about who counts as family: lineal descendants of a common ancestor “no more than 10 generations removed from the youngest generation of family members,” their spouses, and key employees who have participated in the office’s investment activities “for at least 12 months.” It is strict about everyone else: advise one co-founder or one unrelated co-investor, or describe the office publicly as an adviser, and the exclusion stops applying. The adopting release gives the consequence in a line: the office “will need to register under the Advisers Act (unless another exemption is available) or seek an exemptive order from the Commission.”
Dollar figures appear at that point, as consequences. Registration lands at the SEC or with a state depending on regulatory assets under management, with the boundary at $100 million in 17 CFR 275.203A-1, and a registered adviser with custody inherits a surprise examination (17 CFR 275.206(4)-2). Form 13F is the other place a number bites: discretion over $100 million of section 13(f) securities under 15 U.S.C. § 78m(f)(1), where the SEC’s official list settles what counts and coins held directly sit outside it.
The outsourced middle, and what it leaves untouched
Between running it yourself and hiring staff sits an outsourced arrangement: an outside firm handling reporting, reconciliations, bill payment, custody administration and the filing calendar, with no payroll, premises or second entity for the family to govern. For most households arriving at this question, that is where I would begin, and a full in-house build is what you graduate to once the count justifies it.
Two things it leaves untouched. The count stays where it was, so you have changed who reconciles while the number of things needing reconciliation stays put. And the decisions stay yours, because a firm serving several unrelated families is an investment adviser in its own right, which puts the exclusion analysis on their side of the table and makes their registration something you can look up.
What I actually see
The first pattern is the hire that arrives before the job exists. A family recruits someone impressive, and there is no allocation policy, no reporting cadence, no authority matrix and no chart of accounts, so year one goes into archaeology. The policy document costs almost nothing and is what makes the hire productive.
The second is the family office that exists as a name. An LLC, a logo in an email signature, a bank account. Nobody is employed by it and nothing is administered through it, and its practical effect is that co-investors outside the family now believe they have an adviser. That perception is what the third condition exists to prevent.
The third is the office that grows past the exclusion without anyone noticing. A co-founder’s tokens get folded in because the reporting already exists. A family friend asks for the same treatment. An unrelated investor is admitted to the vehicle. Every step is small and reasonable, and nobody re-reads paragraph (b).
Here is the check I would run before spending anything. Pick a month that has already closed and produce, without asking anyone for help, one statement covering every entity, account and wallet, balances struck at the same timestamp, plus who authorized each transfer above a threshold you consider material. Time yourself, count the people you interrupted, multiply the hours by twelve. That figure is what the function costs today, and it is the comparison for a hire, an outside firm, or a narrower fix such as a single reporting layer.
Where this goes wrong
The function gets bought as a headcount and never defined as a set of decisions.
The failures repeat. An office built around one indispensable person, so signing authority and institutional memory leave together. A family office entity with no budget and no employees, which changes the letterhead and nothing else. Co-investors admitted casually until the exclusion has stopped applying and the analysis was never run. Recovery material still in the founder’s safe while the office reports on assets it cannot reach. Software bought in place of a chart of accounts, so the dashboard is confident and wrong. And the version that ends in correspondence with a regulator: an office describing itself publicly as an adviser while relying on an exclusion that forbids precisely that.
The decision rule
- Count the six numbers on one page: entities, jurisdictions, signers, counterparties, billing professionals, claimants.
- Multiply rather than add. Entities times counterparties times closes per year is the workload someone absorbs.
- Price the status quo: twelve months of invoices plus your own hours at a rate you would pay a stranger.
- Name the decisions the office will own before naming a role: allocation, custody, signing authority, reporting cadence, distributions, tax filings.
- Run the exclusion analysis under 17 CFR 275.202(a)(11)(G)-1 against everyone you intend to serve, and repeat it whenever that list changes.
- Settle the deduction question with your CPA before signing a lease, an employment agreement or a service contract.
- Begin with the outsourced version unless the count and the price both argue otherwise, and give it real authority over the decisions in step 4.
- Recount every year, and on any event that adds an entity, a jurisdiction or a signer.
Where this sits
This question sits upstream of the rest of the family office cluster. Governance is what the office runs on once it exists, the allocation policy and the investment policy statement are the first documents worth paying for, and reporting is where the count becomes visible. The custody and trusts hubs hold the mechanics.
These questions cross professional boundaries, and the join is what fails. An attorney forms the entities and never sees the custodian’s signer list. A CPA files the returns and holds no view on the quorum that moved the coins. A custodian onboards a company and never reads the trust that owns it. Each is right inside their own lane, and the family is the only party standing where all of them meet, usually without the records to do it. If you would rather have one reconciled picture of every entity and account than six professionals each holding a correct piece of it, family office administration is where my firm starts.
