Family Office Tax Structure: Can a US Family Office Deduct Costs?

How is a US family office taxed, and why are investment fees not deductible?

A US family office is taxed according to its entities and actual activities. Family members cannot deduct ordinary investment fees federally; a genuine management business may deduct qualifying business costs.

A domestic LLC with multiple owners generally defaults to partnership treatment. A single-owner LLC's income and deductions generally belong to its owner unless it elects corporate treatment. A partnership reports income and deductions, and its owners generally pay tax on their allocated shares. The LLC label does not establish a business (IRS: LLC classification, section 702).

Section 212 covers ordinary investment-management expenses, while section 162 allows ordinary and necessary expenses of carrying on a trade or business (section 212, section 162).

Costs attributable to an operating business or rental property follow separate deduction rules, so a mixed office must separate those costs from portfolio advice; see rental expenses (section 62).

Ordinary investment advisory fees are miscellaneous itemized deductions barred permanently at the federal level by section 67(h); the investor-fund and fee rules explain that distinction (section 67). New York and California may still allow these fees under their state itemized-deduction rules (New York guidance, California instructions).

Moving those same investor expenses into a family partnership does not automatically change their character. Under section 67(c), passing individual investment expenses through a partnership does not make them deductible. A genuine management business must support its own section 162 deductions; the family's investment LLCs do not become businesses just because they hire it (section 67(c)).

What did the Lender Management case decide?

The Tax Court allowed Lender Management's costs as section 162 business expenses, rather than section 212 investment expenses. The court examined services, compensation and client relationships together; its memorandum opinion does not give every family office the same result (T.C. Memo. 2017-246, pages 28–38).

The facts that supported the result included:

The court scrutinized the family relationships closely. Clients did not all own the management company, did not act with one shared objective, and could withdraw investments under the arrangements the court examined. Those facts helped distinguish a business relationship from informal help among relatives.

The five employees are evidence from that case, not a statutory minimum. Neither an asset threshold nor a standard ownership split in the opinion guarantees deductions. An office owned in the same proportions as its investment clients lacks the court's distinction between the managers and investment owners. Smaller offices and a single household also need their own analysis.

What would a Lender Management family office structure require?

A possible structure separates the investment owners from an office that earns compensation for real services. Forming another LLC or replacing the word fee with profits interest is not enough.

The court's reasoning suggests reviewing these matters before implementation:

1. Identify the clients. Map each family branch, investment LLC and trust to its beneficial owners and investment needs.
2. Separate the management activity. Decide who owns the office, who works there, who pays staff and which services each client receives.
3. Document authority and compensation. A lawyer should prepare agreements covering management duties, profit allocations, withdrawal terms and conflicts.
4. Make the arrangements work in practice. Keep evidence of services and actual decisions by clients with separate interests, rather than documents that exist only for a tax return.

These are review points drawn from the court's fact-specific analysis, not a checklist that assures business status. A family does not need to create disagreements; its genuine ownership and client relationships must support the arrangement.

A profits interest gives the office a partner's share of future profits. A valid allocation shifts income from the investing family members to the office, which reports that income and its qualifying business deductions. Paying an ordinary advisory fee instead leaves the investors reporting that income without a federal fee deduction (section 702).

If an allocation and related payment are effectively compensation outside the recipient's role as a partner, section 707(a)(2)(A) can treat them as a service payment. Payments determined without regard to partnership income can instead fall under the guaranteed-payment rule. Current section 707(a)(2)(A) applies without waiting for regulations. If it turns the allocation into an ordinary advisory fee, the family's federal fee deduction is generally barred. A nearly certain payout needs review (section 707).

How is the office's profits interest taxed?

A genuine partnership profit allocation generally keeps the character of the underlying income. The office may receive interest, dividends or capital gains, while claiming qualifying business expenses separately; receiving a profits interest does not make all income capital gain or all costs deductible (section 702).

If the management LLC is taxed as a partnership, those items pass through again to its owners. Allocations must follow the partnership rules, including section 704's requirement for substantial economic effect or allocation according to the partners' interests (section 704). For gifted family interests, section 704(e) requires allowance for reasonable compensation for the donor's services; certain family purchases count as gifts.

Owner-level basis, at-risk and passive-loss limits can defer deductions. For owners who do not materially participate, business losses may be passive and generally cannot offset portfolio income. Section 461(l) also defers the portion of net business losses above $256,000 ($512,000 jointly), calculated across the owner's businesses; see business losses (sections 469 and 461).

Section 1061 can reclassify certain long-term gains when the relevant holding period does not exceed 3 years, including on a taxable sale of an applicable service interest to a related family member; a pure gift does not itself trigger that transfer rule but preserves carried-interest status (regulation 1.1061-5); see carried-interest holding periods (section 1061).

Before granting an interest, review grant and vesting tax. A qualifying nonvested profits interest can avoid both without an 83(b) election (Revenue Procedure 2001-43). If an election is needed, the service provider signs Form 15620 or a compliant statement and files within 30 days after transfer; see ownership for money and services (Form 15620).

Can a trust deduct investment fees that family members cannot?

A non-grantor trust generally cannot deduct the ordinary investment advisory fee an individual investor would incur. Section 67(e) preserves qualifying administration costs that would not arise if the property were held by an individual, including a qualifying extra advisory charge caused by the trust's circumstances (section 67(e), Treasury regulation 1.67-4).

The deductible advisory portion is limited to the extra cost above what an individual would normally pay. Ordinary balancing between current beneficiaries and future beneficiaries is not enough by itself. Ask for an invoice that identifies the additional work and a reasonable comparison with individual advisory fees.

A single trustee, legal or accounting bill combining administration and investment advice may need to be split. For a bundled fee not calculated by the hour, the ordinary investment-advice portion is generally nondeductible and the remainder deductible. Separately billed costs and payments to third parties still need individual classification; bundling does not make an otherwise nondeductible payment deductible (Form 1041 instructions: bundled fees).

A grantor trust is generally ignored for income tax, with income and deductions belonging to its deemed owner. Putting personal investments in that trust does not create the non-grantor trust exception (Form 1041 instructions: grantor trusts).

Would a trader fund or a corporation work instead?

A different structure works only if its actual activities and total tax consequences support it. Changing the entity does not establish a trader business or remove tax on the family's investment income.

The trader test requires substantial, continuous and regular activity seeking profit from daily price movements rather than dividends, interest or investment appreciation; see trader versus investor funds (IRS Topic 429).

A C corporation generally pays federal tax at 21%, and dividends are included in shareholders' income, creating two potential tax layers (section 11, section 301). Ordinary investment fees paid by family members or their investor LLCs to a management corporation remain federally nondeductible.

Personal holding company rules can reach a corporation with mainly investment income and ownership concentrated among a few individuals. If it meets both income and ownership tests, it may also owe 20% on undistributed personal holding company income, in addition to ordinary corporate tax. Income definitions, indirect ownership and statutory exceptions need review; not every management corporation qualifies (sections 541 and 542). A corporation outside those rules may instead face accumulated earnings tax if it retains earnings to avoid shareholder tax (sections 532 and 533).

What agreements, books and records must the office keep?

A family office needs records that establish both its business activity and each expense's purpose. Books should reflect the signed arrangements and the services actually performed, as required by the general tax recordkeeping rules (section 6001).

• An entity chart showing legal and beneficial ownership, including trust status.
• Signed management and operating agreements, amendments and withdrawal terms.
• Payroll records, staff duties, invoices and evidence of work for each client.
• Separate ledgers for investment returns, management compensation and personal spending.
• Profit-allocation calculations, capital accounts, tax basis and reconciled transfers between entities.
• Client instructions, meetings and decisions showing whose needs the office served.

Household bills, personal travel and similar family spending do not become business expenses when the office pays them (section 262). A mixed invoice needs a supportable separation by purpose.

For partnership returns required to be filed in 2027, late or incomplete filing can bring a penalty of $260 per month or partial month, up to 12 months, for each person who was a partner at any time during the tax year, unless reasonable cause applies. Eligible late original returns filed within 3 years of their original due date, with a qualifying 3-year compliance history, may receive automatic first-time relief; this does not cover the incomplete-return penalty (IRS relief update); see late-filing penalties (Revenue Procedure 2025-32, section 4.55, section 6698). Assign responsibility for every entity's books and returns through family office accounting across entities.

An LLC taxed as a partnership with a trust or partnership member cannot elect out of centralized audits. The entity generally pays an audit underpayment unless its representative elects to shift it to the reviewed-year partners using Form 8988 within 45 days after the final adjustment notice is mailed (section 6221, Form 8988). If unpaid 10 days after notice and demand, the IRS may assess adjustment-year partners' shares, generally within 2 years of that demand; see partnership audit rules (section 6232(f)).

We just sold the family business: when should the structure be decided?

Review the family office structure before committing to management arrangements, granting service interests or starting operations. If the business sale is still pending, review ownership and the intended use of proceeds before signing commitments.

Selling a business does not itself establish a management business. Section 162 concerns expenses incurred while carrying on a business; pre-opening costs may instead be start-up expenditures under section 195. Qualifying start-up costs receive a deemed election: up to $5,000 when business begins, reduced by costs above $50,000, with the rest over 180 months. The office can instead elect capitalization on its timely opening-year return, including extensions (regulation 1.195-1). Later operations do not establish an earlier business (sections 162 and 195).

Gather the sale documents, existing entity chart, projected staffing, agreements and compensation terms. Separate costs of the sale, investing the proceeds, personal planning and opening the management business. Each purpose needs its own treatment.

What does the structure cost to run compared with what it may save?

Compare total after-tax cost with the services the family needs. A deduction does not reimburse the expense or establish business status.

Model profitable and loss years. A responsible person who willfully fails to pay withheld payroll taxes can personally owe 100% of those taxes under section 6672. Assessment generally has a 3 years limit measured from the later of return filing or April 15 of the following year; an unfiled return has no limit. Collection generally lasts 10 years after assessment, subject to extensions or suspensions; see unpaid payroll taxes (IRS manual).

For an office operating in New York City, review UBT separately, including whether its profits interest qualifies for investment-income treatment; see NYC tax for fund managers (NYC tax guidance, NYC Comptroller's discussion).

Example

This example is illustrative; all amounts are US dollars and no tax saving is calculated.

After a business sale, three family branches hold investments through separate LLCs taxed as partnerships. A separate management LLC employs four people and serves each branch under written agreements. The investment LLCs grant the office a contingent profits interest for future services instead of paying an advisory fee.

Assume the agreements validly allocate US$600,000 of current-year profits to the office and the office receives that much cash. The office pays US$500,000 of operating costs, all assumed to qualify for current deduction under section 162. Its cash remaining is US$100,000. Under the allocation, the investing members report US$600,000 less income from those LLCs; an ordinary US$600,000 advisory fee would leave that income with them and no federal fee deduction.

The returns must still report the US$600,000 by income type and the US$500,000 of deductions correctly. Cash remaining is not a tax calculation: carried-interest rules and each owner's basis, at-risk, passive-loss and excess-business-loss limits may change the result.

If the office earns no profit allocation the next year but incurs the same costs, it needs US$500,000 from reserves or financing. The US$500,000 business loss passes to owners subject to those limits; no immediate deduction is assumed. Neither scenario establishes business status; the actual services, ownership and compensation must support it.

Different for you?

• A sale is pending, the office has staff, or the family has three or more entities: bring the entity chart, agreements, payroll records and fee or profit terms for a tax structure review, books, capital accounts and returns through family office tax and accounting services.
• Children, parents or spouses will own the investment LLCs: ownership and filing treatment belong in family LLCs.
• A holding LLC will sit above several entities: see running more than one business.
• The office or investment LLCs are considering a state tax election: see pass-through entity tax elections.
• Books, intercompany balances or returns are missing: gather every entity's prior returns, capital statements and records for family office accounting across entities; missed partnership returns can accumulate penalties while records are reconstructed.
• Owners, trusts or activities span the US and Canada: the federal analysis here needs a separate cross-border tax review.
