FINRA Rule 2040: Prohibitions, Exceptions, and Penalties

FINRA Rule 2040 bars a member firm from paying commissions, fees, or other compensation to an unregistered person whenever the payment and the underlying activity would require that person to register as a broker-dealer under Section 15(a) of the Securities Exchange Act. Three narrow exceptions exist: pay for work unrelated to securities, continuing commissions to a retired representative under a pre-existing written contract, and referral fees to foreign finders who introduce foreign customers. Everything else is prohibited, and firms that route money around the rule face fines, disgorgement, and suspensions.¹

What the Rule Prohibits

Rule 2040(a) applies to any member firm or associated person and reaches both direct and indirect payments. A firm cannot pass money through a registered representative to reach an unregistered recipient and treat the arrangement as compliant. Labels do not control. A “consulting fee” that is really a commission for bringing in accounts is exactly what regulators look for. The question is always whether the underlying activity, viewed on its economic substance, would require the recipient to register under Section 15(a), which makes it unlawful for an unregistered person to use interstate commerce to buy, sell, or solicit securities transactions.²

Paying for Non-Securities Work

The cleanest permitted category is pay for services that have nothing to do with securities. Salaries for administrative staff, rent to a landlord, invoices from an IT contractor, cleaning services — none of these trigger registration concerns because the recipient is not doing anything that resembles broker-dealer activity.

The trouble starts when compensation structure links an unregistered person’s pay to the securities business. An office manager whose bonus rises with new account openings, or a technology consultant paid a percentage of trading revenue, begins to look like a person receiving transaction-based compensation for securities activity. A flat fee for a defined administrative service passes. A variable payment that grows with the firm’s securities volume does not.

Documentation matters. A firm should be able to show an examiner what the unregistered person actually does, how the fee is calculated, and why the work has no connection to soliciting clients, recommending investments, or handling customer funds.

Continuing Commissions to Retired Representatives

Rule 2040(b) lets a firm keep paying commissions — sometimes called trail commissions — to a representative who has retired from the securities industry entirely. The rule’s definition of “retiring registered representative” includes departure due to total disability, not only voluntary retirement.¹

Four conditions all have to be met:

A bona fide written contract entered in good faith while the representative was still registered. A post-retirement handshake will not do.
A complete exit from the securities industry. Moving to another firm or starting an advisory practice ends eligibility.
An explicit contractual prohibition on soliciting new business, opening new accounts, or servicing the accounts that generate the payments.
Beneficiary provisions so that payments can continue to a named beneficiary or to the estate if the retired representative dies.

These conditions are enforced strictly. A retired representative who calls a former client to encourage them to stay put has arguably crossed the solicitation line, which can jeopardize the entire arrangement. Firms paying trail commissions should have a way to monitor for that.

Referral Fees to Foreign Finders

Rule 2040(c) permits transaction-based compensation to a foreign finder who refers foreign customers to the firm. This is the only place in Rule 2040 that resembles a traditional referral fee, and the conditions are demanding.¹

The finder must be a foreign national or foreign entity operating outside the United States, and the referred customers must also be foreign. The customers can transact in U.S. or foreign securities, but the relationship must originate abroad.

Before paying anything, 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 that the arrangement does not violate any applicable law in the finder’s home country.
Give each referred customer a written disclosure of the compensation arrangement, similar to disclosures required under the Investment Advisers Act.
Obtain and retain a signed customer acknowledgment of that disclosure.
Indicate on every trade confirmation that a referral or finder’s fee is being paid.

The firm also has to keep records of payments made to finders and preserve the underlying agreements for FINRA inspection.

No Equivalent for U.S. Finders

One of the most common misreadings of Rule 2040 is the assumption that some parallel path exists for paying a domestic finder. It does not. The rule provides a foreign finder exception and deliberately omits a domestic one. Paying a U.S. resident transaction-based compensation to introduce 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 steers wealthy contacts to a brokerage might feel like a benign referral source, but paying them for the introduction turns them into an unregistered broker under federal securities law. Flat “consulting” fees do not solve the problem if the real purpose of the payment is to reward client introductions. Regulators evaluate economic substance, not invoice labels.

The M&A Broker Carve-Out

A separate federal statutory exemption, sitting 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 must be an “eligible privately held company,” meaning that in the fiscal year before the M&A broker was engaged it 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 sits around 2027. The broker cannot have custody of client funds or securities, and the transaction cannot involve a public offering. The exemption covers the sale of an entire business, not a capital raise dressed up as an acquisition. Firms relying on it should keep documentation showing the size thresholds were met and that the buyer intended to operate the business.

Documenting Why a Payment Is Permitted

Whenever a firm pays an unregistered person and believes the payment sits outside Rule 2040’s prohibition, Supplementary Material .01 requires it to affirmatively determine that the recipient does not 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 comparable facts.
A no-action request submitted to SEC staff seeking confirmation that the arrangement will not draw enforcement.
A written legal 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. For ongoing payments, the firm should revisit its analysis periodically to confirm the unregistered person has not drifted into activities that look like securities solicitation. Books and records must document the determination, which in practice means a file an examiner can pull during a routine review.

Penalties for Getting It Wrong

Rule 2040 violations produce real consequences on both the FINRA and SEC sides. A registered representative who paid roughly $27,000 in commissions to an unregistered individual over a few months was fined $2,000 and suspended for ten business days. In a larger matter, 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 its compensation arrangements comply with Rule 2040.

The SEC pursues the same conduct under Section 15(a) and can impose heavier sanctions. In a 2025 action, three investment adviser representatives who solicited investors, provided marketing materials, and received transaction-based compensation without broker registration 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, and all three agreed to six-month industry suspensions.³

Beyond the numbers, a Rule 2040 finding often becomes a supervisory deficiency finding, forcing an overhaul of the firm’s compliance program, and for the individuals involved it produces a disciplinary record that follows them through BrokerCheck for the rest of their careers.
