SEC Regulation Best Interest (Reg BI), effective June 30, 2020, requires broker-dealers to act in the best interest of retail customers when recommending a securities transaction or investment strategy involving securities. Reg BI establishes four distinct obligations: Disclosure Obligation (full and fair disclosure of material facts), Care Obligation (reasonable basis to believe the recommendation is in the customer's best interest), Conflict of Interest Obligation (establish, maintain, and enforce policies addressing conflicts), and Compliance Obligation (establish written policies and procedures reasonably designed to achieve Reg BI compliance). The SEC and FINRA have cited Reg BI supervisory failures in examinations continuously since 2021 and have brought enforcement actions for systemic failures. This 18-item checklist covers every component of a compliant Reg BI program.

SEC/FINRA Compliance Checklist for Regulation Best Interest (Reg BI)
Confirm Form CRS is current, accurate, and reflects actual services and conflicts
Form CRS (Customer Relationship Summary) must describe in plain English: the types of client relationships and services offered, fees and costs, conflicts of interest, required legal standards, and disciplinary history. Review Form CRS against actual firm practices — discrepancies between Form CRS and actual services are a Reg BI violation. Update Form CRS within 30 days of any material change. Retain each version with the effective dates.
Ensure Form CRS is delivered at or before the time of first recommendation or account opening
Form CRS must be delivered to retail investors at or before the earliest of: entering into an investment advisory relationship, making a recommendation of securities, or opening a new account. Electronic delivery is permitted but must be actually delivered — directing a customer to a website where Form CRS is posted is insufficient delivery. Maintain delivery records with date, method, and recipient for SEC and FINRA examination purposes.
Document that each recommendation was reviewed for compliance with the Care Obligation
The Care Obligation requires a broker-dealer to have a reasonable basis to believe that the recommended transaction or strategy is in the best interest of the particular retail customer at the time of the recommendation. Documentation should capture: the customer's investment profile (financial situation, tax status, investment experience, investment time horizon, liquidity needs, risk tolerance, investment objectives), the specific recommendation, the analysis supporting why the recommendation is in the customer's best interest, and whether alternatives were considered.
Collect and maintain complete customer investment profiles for all retail accounts
Reg BI's Care Obligation requires knowledge of the specific retail customer. Collect and document: age, annual income, net worth, investment experience, investment time horizon, liquidity needs, risk tolerance, and investment objectives. Update profiles when customers inform you of changes. Profiles must be complete before any recommendation is made — recommendations made without adequate customer profile information fail the Care Obligation.
Establish policies requiring consideration of reasonably available alternatives
The Care Obligation requires a broker-dealer to consider the costs and risks of a recommendation and to evaluate whether a less expensive or less risky alternative would be in the customer's best interest. Supervisory procedures must require registered representatives to document their consideration of alternatives, particularly for: more expensive share classes of mutual funds, higher-cost products where lower-cost alternatives exist, recommendations to roll over assets from lower-cost accounts, and complex products with retail alternatives.
Implement and document the Conflict of Interest policies required by Rule 15l-1(a)(2)(iii)
The Conflict of Interest Obligation requires written policies that: identify all conflicts of interest associated with recommendations to retail customers, disclose material conflicts to retail customers, eliminate or mitigate material conflicts that cannot be eliminated. Document each identified conflict and the mitigation measure: sales contests based on securities recommendations must be eliminated; differential compensation structures must be disclosed and supervised; conflicts from third-party revenue (12b-1 fees, revenue sharing) must be disclosed.
Prohibit or remediate any compensation practices that conflict with Reg BI
Reg BI explicitly prohibits sales contests, sales quotas, bonuses, and non-cash compensation that are based on the sale of specific securities or specific types of securities within a limited period. Review all compensation plans, bonus structures, and non-cash incentives against this prohibition. Quota-based awards that incentivize recommending one product over another to customers are prohibited — not just required to be disclosed. Document the compensation review and any changes made.
Establish written supervisory procedures specifically designed for Reg BI compliance
The Compliance Obligation requires written policies and procedures reasonably designed to achieve Reg BI compliance. WSPs must address: care obligation documentation, customer profile collection and updating, conflict identification and mitigation procedures, Form CRS delivery and updating, registered representative training on Reg BI, escalation procedures for potential Reg BI violations, and regular testing of Reg BI compliance. FINRA examiners review whether WSPs are specifically designed for Reg BI rather than simply updated NASD suitability procedures.
Train all registered representatives on Reg BI requirements and document training completion
Reg BI training must cover: the four obligations, the difference between Reg BI and prior FINRA suitability standards, specific scenarios relevant to the firm's business, documentation requirements, and conflict of interest disclosures. Training must be updated when regulatory guidance is issued or when examination findings identify gaps. Document all training: date, content, attendees. New registered representatives must complete Reg BI training before making recommendations.
Implement a supervisory review process for high-risk Reg BI recommendations
Establish an exception-based review process for recommendation categories with elevated Reg BI risk: recommendations to roll over retirement assets (compare costs, services, and investments), recommendations of complex products (structured notes, leveraged ETFs, non-traded REITs), recommendations to move assets between account types, and recommendations involving high-commission products where lower-cost alternatives exist. Document the review, the reviewer's findings, and any follow-up.
Review all mutual fund share class recommendations for best interest compliance
Recommending a higher-cost share class (e.g., Class A or C shares) when a lower-cost share class (e.g., Class I, R6, or no-load equivalent) is available and suitable is a paradigmatic Reg BI violation. Review your fund recommendation process: do registered representatives have access to information about all available share classes? Do supervisory procedures require consideration of the least expensive suitable share class? FINRA has cited this as a top enforcement priority under Reg BI.
Document and test your rollover recommendation process for Reg BI compliance
Recommendations to roll over 401(k) or other retirement assets into IRAs managed by the broker-dealer are among the highest-risk Reg BI recommendations. Required documentation: the customer's specific reasons for the rollover, comparison of costs between the current plan and the proposed IRA, comparison of investment options, services available, distribution options, protection from creditors, and required minimum distribution implications. This documentation must exist before the recommendation is made.

Frequently Asked Questions
What is the difference between Regulation Best Interest and FINRA's prior suitability standard?
FINRA's suitability rule (Rule 2111) required recommendations to be 'suitable' for the customer based on their investment profile — a product was suitable if it matched the customer's general financial situation and needs. Regulation Best Interest requires that the recommendation be in the customer's 'best interest' at the time of the recommendation — a higher standard that requires considering costs and reasonably available alternatives, not just suitability. Additionally, Reg BI imposes an explicit Conflict of Interest Obligation that requires identifying, disclosing, and eliminating or mitigating conflicts — suitability required only that conflicts not compromise the basis for the recommendation. Reg BI also adds a Compliance Obligation requiring specific written supervisory procedures, and Form CRS delivery requirements that have no direct equivalent under prior suitability rules.
Does Regulation Best Interest apply to all investment recommendations made to retail customers?
Reg BI applies when a broker-dealer makes a 'recommendation' of a 'securities transaction or investment strategy involving securities' to a 'retail customer.' All three elements must be present. A retail customer is a natural person who receives a recommendation for personal, family, or household purposes. Investment strategies involving securities include account type recommendations (e.g., recommending a retail customer open a fee-based account) and rollover recommendations. Reg BI does not apply to institutional customers, does not apply to investment advisers (who are subject to fiduciary duty under the Advisers Act), and does not apply to unsolicited transactions (though FINRA suitability obligations still apply to unsolicited transactions).
What are the SEC's and FINRA's enforcement priorities for Regulation Best Interest in 2026?
Based on SEC examination priorities for 2025-2026 and FINRA's examination findings reports, key Reg BI enforcement areas include: (1) documentation of the best interest analysis, particularly for recommendations to roll over retirement assets, (2) mutual fund share class recommendations and consideration of lower-cost alternatives, (3) recommendations of complex products (structured notes, non-traded REITs, leveraged/inverse ETFs) to retail investors, (4) compensation conflict mitigation — specifically whether prohibited sales contests or differential compensation structures were actually eliminated, (5) Form CRS accuracy and delivery records, and (6) the adequacy of Reg BI-specific supervisory procedures and registered representative training.
