A related party transaction is any deal between two parties who already share a controlling or influential connection: a company and its CEO, a parent and its subsidiary, a business and a major shareholder, or a person and their close relatives. The concern behind the label is simple. When the people on both sides of a deal answer to the same interests, the price and terms may not match what independent parties would have agreed to, and that gap is where shareholders lose value, tax bills get distorted, and regulators get involved.
Who Counts as a Related Party
The definition is deliberately broad. Under U.S. accounting standards, a related party is any person or entity that can control or meaningfully influence another’s financial and operating decisions. Parent companies and their subsidiaries qualify, and so do two subsidiaries that share a common parent. An investor holding 20 percent or more of a company’s voting stock is generally presumed under GAAP to have significant influence, which pulls them into the related party category automatically.
Executives, directors, and other senior leaders with real decision-making power are related parties. So are their immediate family members, including spouses, parents, children, and siblings. Anyone owning more than 10 percent of a company’s voting stock is included, along with any business entity that one of these insiders controls directly or indirectly.
The relationships look different on paper, but the risk they create is the same: someone with leverage or inside knowledge can steer a deal in their own favor at the company’s expense.
What Kinds of Deals Count
Any transfer of value between related parties qualifies. Buying or selling assets, lending money, providing services, leasing property, or letting someone use corporate resources for free all count. Cash doesn’t have to change hands. If a company lets a director use a corporate jet at no charge, that’s a related party transaction.
The core question is whether the terms are “arm’s length.” In a normal market deal, buyer and seller each negotiate for the best terms they can get, and neither has a personal reason to accept an unfavorable price. When related parties transact, that tension disappears. A company might sell land to its CEO at a steep discount, or pay an executive’s sibling above-market rates for consulting work. The paperwork may look routine while the substance shifts value from the company’s shareholders to the insider. Accounting standards and securities regulations both focus on the economic reality rather than the form. A lease structured to look market-rate still draws scrutiny if the actual rent is double what comparable tenants pay in the same building.
Common Examples
Asset sales between a company and its insiders draw the most attention. A director selling real estate to the company at an inflated price, or a company unloading equipment to a subsidiary at a deep discount, both raise the same valuation question: would an independent counterparty have accepted that price?
Loans between a company and its executives or major shareholders are another frequent flashpoint, often carrying interest rates well below market or no interest at all. Compensation arrangements for senior management, especially stock options and performance bonuses, get scrutiny because the executives who benefit often influence the packages. Service agreements between affiliated entities are common, with parent companies charging subsidiaries management fees that bear little resemblance to what an outside consultant would charge. Leasing arrangements come up regularly, particularly when a company rents space from a building a board member owns. And when a parent guarantees a bank loan for a struggling subsidiary, the guarantee exposes the parent to real financial risk on behalf of a related entity.
Tax Rules That Apply
Several provisions of the Internal Revenue Code specifically target deals between related parties. The consequences range from losing a deduction to having the IRS rewrite the transaction outright.
IRS Reallocation Under Section 482
Section 482 gives the IRS broad authority to reallocate income and deductions among related businesses when their transactions don’t reflect what independent parties would have agreed to. The goal is to determine the “true taxable income” each entity would have reported dealing at arm’s length. The IRS doesn’t need to prove fraud or intentional tax avoidance to invoke this power; it applies any time a controlled transaction fails to produce arm’s-length results.1eCFR. 26 CFR 1.482-1 – Allocation of Income and Deductions Among Taxpayers
This is the provision behind most transfer pricing disputes. If a U.S. parent sells products to its overseas subsidiary at an artificially low price to shift profits abroad, Section 482 lets the IRS adjust the price to market rates and tax the parent on the additional income.
Loss Disallowance Under Section 267
Selling property at a loss to a related party doesn’t produce a deductible loss. Under Section 267, losses on sales between family members, between an individual and a corporation they control (owning more than 50 percent of its stock), between two commonly controlled corporations, and between trusts and their grantors or beneficiaries are all non-deductible.2Office of the Law Revision Counsel. 26 USC 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers
The reasoning is direct: when related parties control both sides of a sale, a “loss” can be manufactured by setting a low price. “Family” here means siblings, spouses, ancestors, and lineal descendants. The disallowed loss isn’t permanently gone; if the related buyer later resells the property at a gain to an unrelated party, the previously disallowed loss can offset part of that gain.2Office of the Law Revision Counsel. 26 USC 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers
Below-Market Loans Under Section 7872
Interest-free or below-market loans between related parties trigger special rules under Section 7872. The IRS treats the forgone interest as if it had actually been paid. The lender is deemed to have transferred the interest amount to the borrower (as a gift, dividend, or compensation depending on the relationship), and the borrower is deemed to have paid it back as interest. Both sides get taxed on the phantom amounts.3Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates
A loan is “below-market” if its interest rate falls below the applicable federal rate published by the IRS. For loans between a corporation and its shareholders, or between an employer and employee, the imputed interest rules don’t apply if the outstanding balance stays at or below $10,000, unless the loan’s principal purpose is tax avoidance. For gift loans between individuals, the same $10,000 floor applies, and for loans up to $100,000 the deemed interest income is capped at the borrower’s net investment income for the year.3Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates
Constructive Dividends
When a corporation transfers value to a shareholder outside the formal dividend process, the IRS can reclassify the transfer as a taxable constructive dividend. Common triggers include selling property to a shareholder below fair market value, canceling a shareholder’s debt, charging below-market rent, or paying unreasonable compensation to a shareholder-employee. The excess value in each case is treated as a distribution taxable to the shareholder.4Internal Revenue Service. Corporations
Constructive dividends are especially painful because neither the company nor the shareholder planned for the bill. The company loses the deduction it thought it had (the “salary” that was really a dividend isn’t deductible), and the shareholder owes tax on income they may not have recognized as a distribution.
SEC Disclosure for Public Companies
Public companies must disclose related party transactions to investors, and the rules are specific. Under SEC Regulation S-K, Item 404, a company must disclose any transaction exceeding $120,000 in which a related person had a direct or indirect material interest. The rule covers transactions completed during the last fiscal year and deals that are merely proposed but not yet finalized.5eCFR. 17 CFR 229.404 – Item 404 Transactions With Related Persons, Promoters, and Certain Control Persons
The disclosure has to identify the related person, explain the relationship, state the dollar amount, and lay out the specific terms. For loans, the company must disclose the largest principal balance outstanding during the period plus any amounts written off. These disclosures appear in the footnotes to financial statements and in proxy filings, giving shareholders the concrete detail they need to judge whether the transaction hurt them.5eCFR. 17 CFR 229.404 – Item 404 Transactions With Related Persons, Promoters, and Certain Control Persons
The Sarbanes-Oxley Loan Ban
One category is flatly illegal for public companies. Section 13(k) of the Securities Exchange Act, added by the Sarbanes-Oxley Act, makes it unlawful for any publicly traded company to extend a personal loan to any of its directors or executive officers. The prohibition covers new loans, maintained balances, arranged credit, and renewals.6Office of the Law Revision Counsel. 15 USC 78m – Periodical and Other Reports
There is a narrow exception. A company in the business of consumer lending, like a bank, can extend credit to its own officers and directors, but only on terms available to the general public, in the ordinary course of business, and at market rates. Personal loans that existed before July 30, 2002, were grandfathered in, provided the company made no material changes to their terms after that date.6Office of the Law Revision Counsel. 15 USC 78m – Periodical and Other Reports
How Companies Approve These Deals
Disclosure rules tell you what to report after the fact. Governance is what stops bad deals before they happen. The board bears ultimate responsibility, but in practice the audit committee handles the work, typically composed entirely of independent directors with no financial ties to management.
A written policy should require directors and officers to disclose potential related party relationships at least annually. When a specific transaction surfaces, the audit committee evaluates whether the deal serves a legitimate business purpose and whether the terms match what an unrelated third party would accept. That second question is where most of the real work happens.
For material transactions, the strongest protection is an independent valuation or formal fairness opinion from an outside firm. A fairness opinion documents a third-party assessment that the financial terms are fair to shareholders. It isn’t legally required in most situations, but it’s the single most persuasive piece of evidence a company can point to if the deal is later challenged. Skipping this step and relying on internal estimates leaves real litigation exposure, especially when the amounts are large or the relationship is visible from outside.
Consequences of Self-Dealing
Directors and officers who participate in undisclosed or unfair related party transactions face personal liability. At its core, a self-dealing transaction is a breach of fiduciary duty, and courts can unwind the deal entirely at the request of harmed shareholders. A director who pushed through a below-market asset sale to a company they control can be held liable for the difference in value, any profits they earned from the breach, and any gains the company would have earned had the breach not occurred.7FDIC. Section 8 Compliance – Conflicts of Interest, Self-Dealing, and Contingent Liabilities
In severe cases, courts can remove a fiduciary from their position altogether. Failing to disclose a material related party transaction can also trigger SEC enforcement. The cost of a proper approval process and an independent fairness opinion is trivial next to the cost of defending an undisclosed related party transaction later.
