Related party transactions are business deals between people or entities that already share a connection outside the deal itself: a company buying a building from its CEO, a parent lending to a subsidiary, a director’s law firm billing the company for legal work. These arrangements are common and often legitimate, but the pre-existing relationship removes the usual market pressure to negotiate hard, which is why accounting standards, SEC rules, and the tax code all impose special disclosure and pricing requirements when they occur.
Who Counts as a Related Party
The accounting definition sits in FASB Accounting Standards Codification (ASC) 850 and casts a wide net. Principal owners holding more than 10 percent of a company’s voting interests are automatically related parties. So is management, which ASC 850 defines to include board members, the CEO, COO, vice presidents in charge of major business functions, and anyone else with policymaking authority. The definition reaches the immediate families of those people too: spouses, parents, stepparents, children, stepchildren, siblings, and in-laws.
Entities qualify through control or significant influence. Control usually means majority ownership of voting shares. Significant influence sits a step below, generally arising when one entity holds between 20 and 50 percent of another’s voting stock. Employee benefit trusts managed by company leadership, like pension or profit-sharing trusts, also fall inside the perimeter.
The tax code draws its own lines, and they don’t perfectly overlap. Under IRC Section 267, related parties include family members (siblings, spouse, ancestors, and lineal descendants), an individual and a corporation where the individual owns more than 50 percent of the stock, a grantor and a trust fiduciary, and various combinations of trusts, estates, S corporations, C corporations, and partnerships sharing common ownership above 50 percent.1Office of the Law Revision Counsel. 26 USC 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers A deal can trigger disclosure under the accounting rules without hitting the tax thresholds, and vice versa, so both frameworks need checking.
Common Forms These Transactions Take
The most visible type is a direct sale or purchase of property. A corporation buys land from its majority shareholder, or a subsidiary sells equipment to a sister company. Leasing is equally common: a company pays rent for office space owned by a director or an entity a board member controls. Prices in these deals deserve extra scrutiny because neither side has the usual incentive to push back.
Lending and borrowing between related parties happen constantly. A parent extends a low-interest loan to a subsidiary to fund expansion, or an executive receives a cash advance on favorable terms. Management fees and consulting arrangements also count, such as a board member’s law firm handling company litigation or a shareholder’s IT company providing technical support. Non-cash arrangements qualify too, including services provided for free or one entity assuming another’s debt.
Executive compensation can cross into related party territory when the structure goes beyond ordinary salary. If a company sells discounted stock to named officers or directors at a price unavailable to other employees or shareholders, the discount must be reported as compensation. Perquisites and personal benefits totaling $10,000 or more for any named executive officer require itemized disclosure in the company’s annual filings.2eCFR. 17 CFR 229.402 – (Item 402) Executive Compensation
Financial Statement Disclosure
Under ASC 850, every company preparing financial statements under U.S. GAAP must disclose related party transactions in the notes. Required disclosures include the nature of each relationship, a description of the transactions for every period an income statement is presented, the dollar amounts involved, and any change in how the terms were set compared to prior periods. Amounts owed to or from related parties must appear as of each balance sheet date. When a company does multiple deals with the same party, the figures are typically grouped by type to give a readable picture of overall volume.3Federal Student Aid. Disclosure of Related Party Transactions in Financial Statements
Public companies carry a heavier burden. SEC Regulation S-X Rule 4-08(k) requires related party amounts to appear on the face of the balance sheet, income statement, and cash flow statement, not just in the notes.
SEC Rules for Public Companies
Publicly traded companies also comply with Regulation S-K, Item 404, which requires disclosure of any transaction exceeding $120,000 in which a related person had or will have a direct or indirect material interest. For smaller reporting companies, the threshold is the lesser of $120,000 or one percent of the company’s average total assets over the last two completed fiscal years.4eCFR. 17 CFR 229.404 – (Item 404) Transactions With Related Persons, Promoters and Certain Control Persons
The disclosure itself is detailed. Companies must identify the related person by name, explain the basis for the classification, describe the person’s interest in the transaction, and report the approximate dollar value of both the transaction and the person’s interest. Loan disclosures add the largest principal balance outstanding during the period, the current balance, principal and interest paid, and the interest rate.4eCFR. 17 CFR 229.404 – (Item 404) Transactions With Related Persons, Promoters and Certain Control Persons
Board Review and Conflict Policies
Disclosure alone doesn’t stop a bad deal; someone has to review it before it closes. The New York Stock Exchange requires that a company’s audit committee, or another independent body of the board, review in advance every related party transaction that triggers disclosure under Item 404. The review must specifically assess potential conflicts of interest, and the committee must block any transaction it finds inconsistent with the interests of the company and its shareholders.
Most large companies maintain a written conflict of interest policy that goes further. A well-designed policy defines who is covered, requires annual disclosure statements from officers and directors, and demands prompt reporting of any new conflict before the board takes up the transaction. When a conflict exists, the interested party should participate only long enough to provide relevant facts, then leave the room during deliberation and voting. Disinterested board members then determine whether the transaction is fair, reasonable, and in the company’s best interest, and the minutes should reflect each step.
Smaller and private companies aren’t bound by NYSE listing rules, but the underlying logic still holds. Auditors will look for evidence that related party transactions were identified, reviewed, and priced at arm’s length regardless of company size.
Tax Consequences to Watch
Disallowed Losses Under Section 267
One tax rule catches people off guard. If you sell property at a loss to a related party, the IRS disallows the deduction entirely. The loss isn’t just deferred; the seller loses it permanently. The buyer gets a partial offset: if they later sell the property at a gain, that gain is recognized only to the extent it exceeds the previously disallowed loss.5Office of the Law Revision Counsel. 26 U.S. Code 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers If the buyer eventually sells at a further loss, the original disallowed amount produces no benefit for anyone.
This rule reaches the full relationship list in Section 267(b), including family members, individuals owning more than 50 percent of a corporation, grantors and their trust fiduciaries, related trusts, S and C corporations with common ownership above 50 percent, and corporations and partnerships with overlapping 50 percent ownership. That 50 percent threshold for entities is much higher than the 10 percent ownership level that triggers related party status for accounting disclosure.
Transfer Pricing Under Section 482
When two or more businesses share common ownership or control, the IRS can reallocate income, deductions, and credits between them if the reported results don’t reflect arm’s length pricing.6Office of the Law Revision Counsel. 26 U.S. Code 482 – Allocation of Income and Deductions Among Taxpayers The test is simple in concept: would two unrelated parties have agreed to these terms? If a parent charges its subsidiary half the market rate for management services, the IRS can adjust both companies’ taxable income to reflect an arm’s length fee.7Internal Revenue Service. Allocation of Income and Deductions Under IRC 482 Section 482 applies whether the entities are incorporated or not, organized domestically or abroad, and whether the mispricing was intentional or accidental.
Constructive Dividends
When a corporation provides a benefit to a shareholder that doesn’t look like a dividend but functions as one, the IRS can reclassify it. Paying a shareholder’s personal debts, letting a shareholder use corporate property without adequate reimbursement, or paying above-market rates for a shareholder’s services can all be treated as constructive dividends, taxable to the shareholder and potentially non-deductible to the corporation.8Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions Closely held businesses are where this issue most often produces an unexpected tax bill.
Documenting Arm’s Length Pricing
Claiming a related party transaction was priced at arm’s length requires more than saying so. For significant transactions, especially cross-border transfers between controlled entities, the IRS expects contemporaneous documentation of the pricing methodology. To avoid penalties under IRC Section 6662, that documentation must exist when the return is filed and be produced within 30 days of an IRS request.9Internal Revenue Service. Review of Transfer Pricing Documentation by Inbound Taxpayers
A transfer pricing study generally includes a functional analysis describing each entity’s role, risks, and assets; identification of comparable transactions between unrelated parties; an explanation of why the chosen pricing method best reflects arm’s length results; and the economic analysis supporting the final numbers. The study must also explain why alternative methods were rejected. Companies that skip this process and get audited face an uphill fight: the IRS can impose its own allocation, and the burden shifts to the taxpayer to prove it wrong.
Penalties for Getting It Wrong
The SEC enforces disclosure requirements through a tiered civil penalty structure. As of January 2025, a basic violation can result in penalties of up to $11,823 per act for an individual or $118,225 for an entity. When the violation involves fraud or reckless disregard of a regulatory requirement, the ceiling rises to $118,225 per individual and $591,127 per entity. For fraud that also creates a substantial risk of loss to others or gain to the violator, penalties reach $236,451 per individual and $1,182,251 per entity.10U.S. Securities and Exchange Commission. Adjustments to Civil Monetary Penalty Amounts These amounts adjust annually for inflation, and each separate act or omission counts as its own violation, so totals multiply quickly.
Criminal exposure is real in the worst cases. Under the Sarbanes-Oxley Act, an executive who willfully certifies a financial report knowing it doesn’t comply with securities laws faces up to 20 years in prison and fines up to $5 million. That provision targets the CEO and CFO certifications on every public company’s periodic filings, and deliberately hiding related party transactions is the kind of misrepresentation it was designed to catch.
