FINRA Rule 3310: AML programs for small broker-dealers
13 min read

Who Rule 3310 binds
Rule 3310 is a FINRA rule, so it binds FINRA member firms: broker-dealers, whatever their size. A firm of three registered people that introduces accounts to a clearing firm needs a written program just as a large self-clearing firm does. What changes with size is how much the program has to say, because most of its parts are risk-based: they scale with the products, the customers and the ways money moves through the firm.
A stand-alone investment adviser is not a FINRA member, so Rule 3310 does not reach it; this guide covers the broker-dealer side only. Where AML sits among a member firm's other duties (supervision, communications, books and records, reporting) is mapped in FINRA compliance for small broker-dealers.

Figures as the rule text states them. The federal figures come from FinCEN's rules in 31 CFR, read on eCFR. How they apply to a given account is a question for your compliance counsel.
One program, two rulebooks
The duty to run an AML program comes from the Bank Secrecy Act, through FinCEN's rule for broker-dealers, 31 CFR 1023.210. Rule 3310 is FINRA's version of that same program, and the federal rule points back to it: a broker-dealer's program must also comply with “the rules, regulations, or requirements of its self-regulatory organization governing such programs”. So a member firm writes one program that meets both. Read side by side, the two texts list nearly the same parts. The one figure FINRA adds is the testing calendar.
FINRA Rule 3310 beside FinCEN’s program rule for broker-dealers
| Part | FINRA Rule 3310 | 31 CFR 1023.210 |
|---|---|---|
| Written program and its approval | “approved, in writing, by a member of senior management” | “a written anti-money laundering program approved by senior management” |
| Suspicious transaction reporting | 3310(a): procedures that can be reasonably expected to “detect and cause the reporting” of transactions under 31 U.S.C. 5318(g) | Not in the list; the reporting duty itself is 31 CFR 1023.320 |
| Internal controls | 3310(b) | 1023.210(b)(1) |
| Independent testing | 3310(c): annual, or every two years for the firms the rule describes | 1023.210(b)(2): by the firm’s personnel or “a qualified outside party”, no cadence stated |
| A designated person | 3310(d): named to FINRA, an associated person, prompt notice of any change | 1023.210(b)(3): “an individual or individuals” responsible for the program |
| Training | 3310(e): “appropriate personnel” | 1023.210(b)(4): “appropriate persons” |
| Customer due diligence | 3310(f)(i)–(ii) | 1023.210(b)(5)(i)–(ii), in the same words |
FINRA Rule 3310; 31 CFR 1023.210(a)-(c)
Two practical points follow. First, an examiner reading your program will read it against both texts, so cite both where they meet. Second, the cadence of the independent test is a FINRA figure: the federal text asks for testing but sets no interval.
The six minimum parts, in a firm of a few people
Rule 3310 says the program “shall, at a minimum” do six things, lettered (a) to (f). Each one becomes a chapter of your written program. The right-hand line is what a small firm usually has to write down to show the part exists; it is our reading, not rule text.
Rule 3310(a) to (f), and what each asks you to write
- 3310(a)Procedures to detect and cause the reporting of suspicious transactionsName the red flags your business actually meets, who reviews them, and who decides whether a SAR is filed.
- 3310(b)Policies, procedures and internal controls for Bank Secrecy Act complianceThe rest of the federal duties that apply to your firm, each with an owner: customer identification, records, government-list checks.
- 3310(c)Independent testingWho tests, how often your firm must, and why that person is independent of the program.
- 3310(d)An AML compliance person, named to FINRAOne named individual, an associated person of the firm, with the contact details FINRA asks for kept current.
- 3310(e)Ongoing training for appropriate personnelWho counts as appropriate in your firm, what they are taught, and the record that they were.
- 3310(f)Risk-based procedures for ongoing customer due diligenceA customer risk profile for each relationship, monitoring, and updates to customer and beneficial-owner information.
Part (f) is the newest. FINRA added it in 2018 to conform the rule to FinCEN's customer due diligence rule (Regulatory Notice 18-19), and the current text has applied since May 11, 2018. It asks for “appropriate risk-based procedures for conducting ongoing customer due diligence”, including understanding “the nature and purpose of customer relationships for the purpose of developing a customer risk profile” and ongoing monitoring that, on a risk basis, maintains and updates customer information, beneficial owners of legal entity customers included.
Writing the program: a build order

Most small firms do not start from a blank page. FINRA lists an AML template for small firms on its compliance tools page, and the template's own page says it provides “text examples, instructions, relevant rules” and other resources for developing an AML plan for a small firm. That page shows updates dated July 18, 2018 and September 8, 2020. A template is a starting point, not a program: until it describes your accounts, your products and your people, and senior management has approved it, it is someone else's.
Six steps, in the order that saves rework
- 01Describe the business you actually doProducts, how accounts are opened, whether you introduce accounts to a clearing firm, where money and securities move. The risk-based parts of the program are only as good as this page.3310(f); 1023.220(a)(2)
- 02Name the AML compliance personAn associated person of the firm, with the authority to run the program day to day, identified to FINRA.3310(d)
- 03Write the procedures, part by partCustomer identification, beneficial owners, monitoring and red flags, SAR decisions and filing, records. FINRA’s small-firm template offers text examples to start from; your business fills them in.3310(a), (b), (f)
- 04Have senior management approve it in writingA signed and dated approval of the version in force. Keeping each superseded version with its approval shows which program applied when.FINRA Rule 3310
- 05Train the people who meet the riskAccount openers, anyone who moves money or securities, anyone who reviews alerts.3310(e)
- 06Book the independent testOn the calendar the rule sets for your firm, with a tester the rule allows.3310(c); 3310.01
The order matters because the first step sets the size of every other one. A firm that sells only mutual funds on application, with no customer cash passing through its own hands, writes a shorter monitoring chapter than a firm whose customers wire money in and out. Both still write every chapter.
Suspicious activity and the SAR clock
Part (a) of Rule 3310 asks for procedures that can be reasonably expected to “detect and cause the reporting of transactions required under 31 U.S.C. 5318(g)”. The reporting itself is FinCEN's rule for broker-dealers, 31 CFR 1023.320. A transaction must be reported when it is conducted or attempted by, at or through the firm, “involves or aggregates funds or other assets of at least $5,000”, and the firm “knows, suspects, or has reason to suspect” that the transaction, or a pattern it belongs to, meets one of four descriptions.
The four descriptions in 31 CFR 1023.320(a)(2)
- (i)It involves funds derived from illegal activity, or is meant to hide or disguise such funds as part of a plan to violate or evade federal law or a reporting requirement
- (ii)It is designed, through structuring or other means, to evade Bank Secrecy Act requirements
- (iii)It has no business or apparent lawful purpose, or is not the sort the customer would normally be expected to engage in, and the firm knows of no reasonable explanation after examining the available facts
- (iv)It involves use of the broker-dealer to facilitate criminal activity
- Day 0Initial detection of facts that may be a basis for a SAR
- Day 30File no later than this, the standard case
- Day 60Outer limit, only while no suspect has been identified
31 CFR 1023.320(b)(3)
The clock starts at “the date of the initial detection”, so your procedures should say what counts as detection in your firm: an alert reviewed, a rep's escalation, a clearing firm's question. When several broker-dealers are involved in one transaction, the duty rests with each of them, though one report containing all relevant facts is enough. Keep a copy of each SAR and the supporting documentation “for a period of five years from the date of filing the SAR”.
A SAR does not replace FINRA reporting. The federal rule says filing one “does not relieve a broker-dealer from the responsibility of complying with any other reporting requirements” of the SEC or a self-regulatory organization, so an event listed in Rule 4530 still goes to FINRA on its own clock; see the Rule 4530 reporting guide. Firms that monitor trading activity with software compare the options in trade surveillance software.
Knowing the customer
Three federal duties sit under this heading, and the program has to cover each. The customer identification program (CIP) comes first: FinCEN requires a broker-dealer to keep a written CIP “appropriate for its size and business”, and says the CIP “must be a part of” the AML program. Its procedures must let the firm “form a reasonable belief that it knows the true identity of each customer”.
What the CIP obtains before an account is opened, at a minimum
| Information | From whom, and in what form |
|---|---|
| Name | Every customer |
| Date of birth | An individual |
| Address | An individual: a residential or business street address. A company, partnership or trust: a principal place of business, local office or other physical location |
| Identification number | A U.S. person: a taxpayer identification number. A non-U.S. person: one or more of the numbers the rule lists, such as a passport number and country of issuance |
31 CFR 1023.220(a)(2)(i)(A)
The firm then verifies identity “within a reasonable time before or after the customer's account is opened”, by documents, by non-documentary methods or both, and the CIP says which and when. It also checks whether the customer appears on any government list of known or suspected terrorists or terrorist organizations designated by Treasury, and gives customers adequate notice that it is asking for information to verify their identities. A small introducing firm may lean on its clearing firm's systems here; the rule allows reliance on another financial institution only on the conditions it sets, so write those conditions into the program rather than assuming them.
CIP records and how long each is kept
| Record | Kept for |
|---|---|
| All identifying information obtained | Five years after the account is closed |
| A description of any document relied on to verify identity | Five years after the record is made |
| The methods and results of non-documentary verification | Five years after the record is made |
| How each substantive discrepancy was resolved | Five years after the record is made |
31 CFR 1023.220(a)(3)(i)-(ii); in all other respects 17 CFR 240.17a-4
In all other respects those records follow Exchange Act Rule 17a-4, the same rule that sets the format of the rest of your books; see SEC Rule 17a-4 and WORM storage.
Beneficial owners of legal entity customers
The second duty applies when the customer is a company, partnership or similar entity. The firm identifies its beneficial owners when a new account is opened, unless the rule excludes the customer or exempts the account, and verifies each one's identity on risk-based procedures. A beneficial owner is each individual who owns “25 percent or more of the equity interests”, directly or indirectly, and the one “single individual with significant responsibility to control, manage, or direct” the entity, such as a chief executive, a managing member or a general partner. By our reading, that puts at least one control person on file for every covered legal entity account, even where no one reaches 25 percent.
Ongoing customer due diligence
The third duty is Rule 3310(f): understand “the nature and purpose of customer relationships for the purpose of developing a customer risk profile”, then monitor to identify and report suspicious transactions and, on a risk basis, keep customer information current. The risk profile is the link between the two halves of the program. A customer whose activity fits the profile raises nothing; activity that does not fit is what the monitoring chapter is there to catch. The suitability and Regulation Best Interest profile your reps already collect overlaps with it, which is covered in the Rule 2111 suitability guide.
The AML compliance person
Part (d) asks the firm to designate “an individual or individuals responsible for implementing and monitoring the day-to-day operations and internal controls of the program” and to identify them to FINRA. That person “must be an associated person of the member”, and the firm gives “prompt notification to FINRA regarding any change in such designation(s)”.
What the firm gives FINRA for the AML compliance person
- Name
- Title
- Mailing address
- E-mail address
- Telephone number
- Facsimile number
FINRA Rule 3310(d)
Supplementary Material .02 adds that each member must “identify, review, and, if necessary, update” that information in the manner Rule 4517 prescribes. Put the review on the same calendar as the rest of your FINRA contact information, and check Rule 4517 itself for its timing.
Independent testing: how often, and by whom
The rule ends that sentence: “in which case such ‘independent testing’ is required every two years (on a calendar-year basis)”. So the test is yearly for any firm that executes customer transactions, holds customer accounts or introduces them: any firm with customer accounts, held or introduced. The two-year cycle is for firms with no customer accounts in any of those senses. Supplementary Material .01 adds that all members “should undertake more frequent testing than required if circumstances warrant”: a new product line, a new way of opening accounts, or findings from the last test.
Who tests is the harder question in a small firm. The tester must have “a working knowledge of applicable requirements under the Bank Secrecy Act and its implementing regulations”, and three people are ruled out.
Who may not run the independent test
- A person who performs the functions being tested3310.01(c)(1)
- The designated anti-money laundering compliance person3310.01(c)(2)
- A person who reports to either of them3310.01(c)(3)
In a firm where the owner is the principal, the compliance officer and the AML compliance person, and the two other staff report to that one person, those exclusions can leave no one inside the firm who may test. That is why the rule allows “a qualified outside party”. Try your own case:
Check your independent test
Tick what is true. Pre-filled with an introducing firm whose compliance officer, also its AML compliance person, plans to run the test.
Independent testing is required
Every year
FINRA Rule 3310(c); 3310.01(a)
This tester, on the rule’s words
May not test
FINRA Rule 3310.01(b)-(c)
When you buy the test, ask the provider who on its side runs it and whether that person also wrote or runs any part of your program. The FINRA compliance consultants compared page reads each firm's own pages for an AML independent test column, alongside branch inspections and the annual reports. A test the rule allows is not automatically a good one: agree the scope in writing (each of the six parts, a sample of accounts and alerts, the SAR decisions) before it starts.
Ongoing training
Part (e) is one line: “Provide ongoing training for appropriate personnel.” FinCEN's rule asks for ongoing training for “appropriate persons”. Neither text sets a frequency, a length or a syllabus, so the program sets them and then follows them. A workable reading for a small firm: everyone who opens accounts, moves money or securities, or reviews alerts is appropriate; each is trained on the red flags of the firm's own business and on the confidentiality of SARs; and the record shows who attended, when, and what was covered.
The AML file an examiner can ask for
A program is judged by what it leaves behind. These are the records it produces, with the rule behind each and the retention period where a rule states one. Rule 3310 itself sets no retention period, so for the first four rows ask your compliance counsel how your firm's books and records duties apply; the Rule 4511 guide and the retention calculator are the place to start.
The AML file, record by record
| Record | Rule | Kept for |
|---|---|---|
| The written program, with senior management’s written approval | FINRA Rule 3310 | No period stated in 3310 |
| The AML compliance person’s designation and the details given to FINRA | 3310(d); 3310.02 | No period stated in 3310 |
| Each independent test: scope, tester, findings, follow-up | 3310(c); 3310.01 | No period stated in 3310 |
| Training given: who, when, what | 3310(e) | No period stated in 3310 |
| CIP records: identifying information | 31 CFR 1023.220(a)(3) | 5 years after the account is closed |
| CIP records: documents, methods, discrepancies | 31 CFR 1023.220(a)(3) | 5 years after the record is made |
| Each SAR filed and its supporting documentation | 31 CFR 1023.320(d) | 5 years from the date of filing |
FINRA Rule 3310; 31 CFR 1023.220(a)(3); 31 CFR 1023.320(d)
Software helps with parts of this file: monitoring alerts and their review, customer records, training attendance. It does not write the program or stand in for the independent tester. Broker-dealer platforms are compared in broker-dealer compliance software, and the full rule text is on FINRA's Rule 3310 page. None of this is legal advice; your compliance counsel is the one to sign off on how the program fits your firm.
Questions small broker-dealers ask about AML
Does Rule 3310 apply to a registered investment adviser?
Not to a stand-alone adviser. Rule 3310 binds FINRA member firms, and an adviser registered only with the SEC or a state is not one. A dual registrant runs a 3310 program for its broker-dealer. This guide does not cover any AML duty outside the broker-dealer rules; ask your compliance counsel about the adviser side.
FINRA Rule 3310
Can our chief compliance officer also be the AML compliance person?
Rule 3310 asks only that the AML compliance person be an associated person of the firm, named to FINRA. It does not say they cannot hold other roles. The catch is the test: the AML compliance person, and anyone who reports to them, may not run the independent test.
FINRA Rule 3310(d); 3310.01(c)
We only trade for our own account. How often do we test?
A member that does not execute transactions for customers, hold customer accounts or act as an introducing broker for customer accounts tests every two years, on a calendar-year basis. The rule's own examples are a firm that “engages solely in proprietary trading or conducts business only with other broker-dealers”.
FINRA Rule 3310(c)
Can we adopt FINRA’s small-firm AML template as our program?
FINRA describes the template as text examples, instructions, relevant rules and other resources for developing a small firm's AML plan. It is a starting point. The program has to describe your own business and be approved in writing by a member of senior management.
FINRA Rule 3310
Do we tell the customer that we filed a SAR?
No. A SAR and any information that would reveal one are confidential, and no one at the firm may disclose them. A subpoena or request for a SAR is declined, and FinCEN is notified of the request and the response.
31 CFR 1023.320(e)(1)
Does filing a SAR cover our FINRA reporting too?
No. Filing a SAR does not relieve the firm of any other reporting requirement of the SEC or a self-regulatory organization, so any event Rule 4530 lists is still reported to FINRA under that rule.
31 CFR 1023.320(a)(1); FINRA Rule 4530
