FINRA Rule 2040: Exceptions, Documentation, and Enforcement

FINRA Rule 2040 prohibits a member firm from paying commissions, fees, or other compensation to a person who isn’t registered as a broker-dealer if the underlying activity would require registration under Section 15(a) of the Securities Exchange Act. Three narrow exceptions apply: payments for work unrelated to securities, continuing commissions to a retired registered representative under a pre-existing written contract, and referral fees to a foreign finder under strict disclosure rules. Outside those categories, the payment is barred, and firms that misjudge the line face fines, disgorgement, and suspensions.¹

What the Rule Prohibits

Rule 2040(a) bars a member firm or associated person from paying compensation, fees, concessions, or commissions to any person whose receipt of those payments and related activities would require registration as a broker-dealer under Section 15(a) of the Exchange Act.¹ Section 15(a) makes it unlawful for an unregistered person to use interstate commerce to buy, sell, or solicit securities transactions.²

The prohibition reaches both direct and indirect payments. A firm cannot route money through a registered representative to an unregistered recipient and call it clean. Labeling a payment a “consulting fee” doesn’t help if the substance of the arrangement is a commission for bringing in accounts. Regulators evaluate the economic reality, not the invoice heading.

Paying Unregistered People for Non-Securities Work

The simplest permitted payments go to people whose work has no connection to securities transactions. Salaries for administrative staff, rent to a landlord, invoices from an IT contractor, fees to a cleaning service — the recipients aren’t doing anything that looks like broker-dealer activity, so registration isn’t triggered.

Trouble arises when compensation structures blur that line. An office manager whose bonus is tied to account openings, or a technology consultant whose pay tracks trading revenue, starts to receive what looks like transaction-based compensation for securities activity. The test is whether the payment is linked in any way to the volume or success of securities transactions. A flat fee for a defined service passes; a variable payment that rises with the firm’s securities business does not.

Documentation matters most when an examiner asks why a vendor was paid. Records should show what services the unregistered person actually performs and how their compensation is calculated, with enough detail to confirm the work involved no soliciting, recommending, or handling of customer funds.

Continuing Commissions to Retired Representatives

Rule 2040(b) lets a firm keep paying commissions to a registered representative who has retired and left the securities industry. The rule’s definition of “retiring registered representative” includes someone who leaves due to total disability, not only voluntary retirement.¹ These trail commissions represent the residual value of the book of business the representative built while registered.

Four conditions all have to be met:

A bona fide written contract entered into in good faith while the representative was still registered. Agreements negotiated after retirement don’t qualify.
Complete exit from the securities industry. Someone who “retires” from one firm and joins another, or who starts an advisory practice, falls outside the exception.
A contractual prohibition on the retired representative soliciting new business, opening new accounts, or servicing the accounts that generate the continuing payments.
Provisions allowing payments to continue to a designated beneficiary, or to the estate if none was named, if the retired representative dies.

These conditions are enforced strictly.¹ A retired representative who calls a former client to suggest they stay at the firm has arguably breached the solicitation prohibition and can jeopardize the entire arrangement. Firms paying trail commissions should have a way to monitor for that.

Foreign Finder Fees

Rule 2040(c) is the only place the rule permits something resembling a traditional referral fee. It allows transaction-based compensation to foreign finders — non-U.S. individuals or entities that refer foreign customers to the firm.¹ The finder must be a foreign national or foreign entity operating outside the United States, and the referred customers must also be foreign nationals or foreign entities. Those customers can transact in U.S. or foreign securities, but the relationship itself has to originate abroad.

Before making payments, the firm has to:

Confirm the finder is not required to register as a broker-dealer in the U.S. and is not subject to disqualification under FINRA’s By-Laws.
Verify the compensation arrangement doesn’t violate applicable law in the finder’s home country.
Give each referred customer a written document explaining the compensation arrangement.
Obtain and retain a signed customer acknowledgment of the arrangement.
Indicate on every transaction confirmation that a referral or finder’s fee is being paid.

The firm must keep records of all payments to finders and make the underlying agreements available for FINRA inspection.¹

There Is No Domestic Finder Exception

One of the most common misreadings of Rule 2040 is that some legal path exists to pay a U.S.-based finder for client referrals. There isn’t. The rule provides a foreign finder exception and deliberately omits a domestic counterpart. Paying a U.S. resident a fee for introducing prospective clients almost certainly triggers a registration requirement for that person under Section 15(a).²

A real estate agent, an accountant, or a business owner who sends wealthy contacts to a brokerage firm might look like a harmless referral source, but paying them transaction-based compensation for the introduction makes them an unregistered broker under federal securities law. Restructuring the payment as a flat consulting fee doesn’t cure the problem if the real purpose is to reward client introductions.

The Separate M&A Broker Exemption

A federal statutory exemption outside Rule 2040 itself allows unregistered “M&A brokers” to receive transaction-based compensation for facilitating the sale of a privately held company to a buyer who will actively manage or control the business. It was codified in 2023.

The target has to qualify as an “eligible privately held company,” which means that in the fiscal year before the broker was engaged, the company had either less than $25 million in EBITDA or less than $250 million in gross revenue. Those thresholds are subject to inflation adjustment every five years from the December 2022 enactment date, so the first potential adjustment would arrive around 2027.

The M&A broker cannot have custody of client funds or securities, and the transaction cannot involve a public offering. The exemption is built for the sale of entire businesses, not for capital raises dressed up as acquisitions. Firms relying on it should keep documentation proving the size thresholds were met and that the buyer intended to actively operate the business.

Documenting the Determination

When a firm pays an unregistered person and believes the payment sits outside Rule 2040’s prohibition, a gut feeling isn’t enough. Supplementary Material .01 requires the firm to affirmatively determine that the recipient doesn’t need to register and to “reasonably support” that determination.¹

FINRA identifies three ways to build that support:

Reliance on previously published SEC releases, no-action letters, or staff interpretations that apply to similar facts.
Submitting the firm’s own no-action request to SEC staff.
Obtaining a written opinion from a reputable, independent U.S.-licensed attorney with expertise in broker-dealer registration.

The determination has to be reasonable on the specific facts. If payments are ongoing, the firm should revisit the analysis periodically to confirm nothing has changed, such as the unregistered person gradually taking on activities that look like solicitation. Books and records documenting the determination need to be available for an examiner to pull during a routine review.¹

Enforcement Consequences

Violations produce real penalties from both FINRA and the SEC. On the FINRA side, a registered representative who paid roughly $27,000 in commissions to an unregistered individual over a few months was fined $2,000, suspended for ten business days, and ordered to pay hearing costs. In a larger case, a firm that routed approximately $19.3 million in transaction-based compensation to unregistered entities set up by its own representatives was fined $75,000 and required to certify that all its compensation arrangements comply with Rule 2040.

The SEC pursues violations under Section 15(a) and can impose steeper penalties. In a 2025 enforcement action, three investment adviser representatives who solicited investors, provided marketing materials, and received transaction-based compensation without registering as brokers were ordered to pay disgorgement and prejudgment interest ranging from roughly $83,000 to $181,000, plus civil penalties of $20,000 to $40,000 each. All three also agreed to six-month industry suspensions.³

Beyond fines and suspensions, a Rule 2040 violation can trigger broader supervisory deficiency findings that force a firm to overhaul its compliance infrastructure. For the individuals involved, a disciplinary record follows them through BrokerCheck. The referral revenue at stake rarely justifies that exposure.
