Books and Records Retention Requirements

Everything the firm creates in the course of serving customers, from order tickets to internal memos to emails, must be preserved for a specific period. The framework is divided: the broker-dealer books-and-records rule governs what records must be made, and the broker-dealer recordkeeping rule governs how long those records must be preserved and in what format. The MSRB municipal-recordkeeping rules run parallel for the municipal-securities side.

Who makes records vs. who preserves them under securities law?

Think of it this way: The books-and-records rule tells the firm what files to open. The recordkeeping rule tells the firm how long to keep each file and what format it can live in. The FINRA records-retention rules and the MSRB municipal-records rules are the parallel tracks for FINRA-specific and municipal records. If a question asks "which rule requires the firm to create this record?" the answer is the broker-dealer books-and-records rule or the MSRB creation rule. If the question asks "how long must the firm keep this record?" the answer is the broker-dealer recordkeeping rule or the MSRB preservation rule.

Exam Tip: Gotchas

• One rule says "make," the other says "keep." The two SEC broker-dealer rules are often confused. A fact pattern asking about creating a blotter points to the books-and-records rule; a fact pattern asking about retention length points to the recordkeeping rule.
• The SEC's broker-dealer BSA cross-reference is just that: a cross-reference, not a retention table. It tells BDs to comply with FinCEN's BSA rules (typically 5-year retention for CTRs, SARs, and customer identification records). Do not confuse the BSA cross-reference with the creation or preservation rules.

What are the standard retention periods for broker-dealer records?

The retention framework has two main tiers for operational records, plus special rules for customer account records and corporate records.

Memory Aid: 6-3-2 framework

• 6 years, first 2 easily accessible: core records and customer account records
• 3 years, first 2 easily accessible: order tickets, confirmations, communications
• Life of enterprise: corporate existence documents
• 5 years: BSA records (CTRs, SARs, customer identification)

Exam Tip: Gotchas

• The shortcut is "6 years, first 2 easily accessible" for core records and "3 years, first 2 easily accessible" for order tickets and communications. The first 2 easily accessible clause is the same in both tiers; it is the total retention (3 vs. 6) that differs.
• Corporate records (articles of incorporation, minute books, stock certificate books, Forms BD, licenses) must be preserved for the life of the enterprise. There is no fixed 3- or 6-year cap on these foundational documents.

How long must customer account records be kept after closing?

This is one of the most commonly missed retention facts on Series 6:

• Customer account records under the customer account information rule and the MSRB municipal-records creation rule are preserved for 6 years AFTER the account is closed
• The 6-year clock does not start at account opening
• A customer who held an account for 20 years and then closes it triggers a new 6-year preservation clock from the close date
• The firm cannot destroy account-opening documents until 6 years after the account is formally closed

The technical text of the broker-dealer recordkeeping rule requires preservation until at least 6 years after the earlier of the date the account was closed or the date on which the information was collected, provided, replaced, or updated. The practical shorthand for the exam is: 6 years after account closing.

Exam Tip: Gotchas

• Customer account records are preserved for 6 years AFTER the account is closed, not 6 years from opening. A 20-year customer who closes an account triggers a new 6-year preservation clock from the close date. This is one of the most-missed facts on the exam.
• Closure does not end the firm's recordkeeping obligations. The retention clock runs from close, not from opening. A firm that purges account records immediately after closure has violated the broker-dealer recordkeeping rule even if the account is fully settled and terminated.

What format and accessibility standards apply to broker-dealer records?

Records may be maintained as:

• Paper originals
• Microfilm
• Magnetic tape
• Electronic storage media

Electronic recordkeeping must comply with the broker-dealer recordkeeping rule's electronic-storage provisions, as amended October 2022 (compliance date May 3, 2023):

• Permitted in either a non-rewriteable, non-erasable format (Write Once Read Many (WORM)), OR
• An audit-trail alternative that preserves a complete time-stamped audit trail of all modifications
• Records must be readily and promptly reproducible for the SEC and FINRA on request
• Third-party recordkeeping services are permitted subject to specific access and undertaking requirements

"Easily accessible" generally means records are available within a reasonable period of time, typically at the firm's principal office or a designated electronic location.

Exam Tip: Gotchas

• The 2022 amendment to the broker-dealer recordkeeping rule's electronic-storage provisions added the audit-trail alternative to the original WORM-only framework. A firm is no longer limited to non-rewriteable, non-erasable media; it may use any electronic system that preserves a complete time-stamped audit trail of modifications. The requirement is tamper-evident recordkeeping, not a specific technology.
• "Easily accessible" is a 2-year standard within each tier. The full retention is 3 or 6 years total, but the first 2 years must be available for prompt production to regulators. Records older than 2 years may be archived to slower-access storage.

How do the MSRB municipal-recordkeeping rules parallel SEC recordkeeping?

The municipal-securities side tracks the SEC framework closely:

• MSRB municipal-records creation rule: requires dealers to make records substantially parallel to the broker-dealer books-and-records rule, focused on municipal securities transactions (529 plans, ABLE accounts, LGIPs, and underlying municipals held in investment companies)
• MSRB municipal-records preservation rule: requires dealers to preserve those records for parallel periods:
  • 6 years for customer account records, trade blotters, and similar core records
  • 3 years for order tickets, trade copies, and communications
  • Account opening records preserved for 6 years after the account is closed (same as the broker-dealer recordkeeping rule)
• The preservation rule explicitly requires first 2 years easily accessible, paralleling the broker-dealer recordkeeping rule structure

Exam Tip: Gotchas

• The MSRB municipal-records creation and preservation rules together mirror the SEC's broker-dealer books-and-records and recordkeeping rules for the municipal-securities side. A Series 6 rep selling 529 plans is subject to both MSRB rules (make and preserve) alongside the FINRA / SEC framework. Both regimes apply in parallel, not one instead of the other.
• A 529 plan sale produces records under both the MSRB creation rule and the SEC's broker-dealer books-and-records rule. The firm does not get to pick one rule and ignore the other; the municipal-securities nature of the transaction triggers MSRB, and the broker-dealer nature of the firm triggers SEC.
