Regulation of broker-dealers is about 12% of the Series 63. A broker-dealer is a person in the business of effecting securities transactions for others (broker) or for its own account (dealer). The questions cluster around four things: the definition, the exclusions from it (especially the no-place-of-business rule), state registration and financial requirements, and the firm’s duty to supervise its agents. The single most-tested limit: a state cannot require more net capital than the SEC does.
This is one of the registration sections of the Series 63, and it rewards precise definitions. The good news is that the logic is consistent: figure out whether someone meets the definition, then check whether an exclusion pulls them back out, then layer on what registration actually requires. This guide walks that path. For the exam basics (format, fee, passing score), start with what the Series 63 is.
What is a broker-dealer under state law?
A broker-dealer is a person engaged in the business of effecting transactions in securities, either for the account of others or for its own account. That one sentence carries the whole definition, so it is worth unpacking the pieces.
The definition, broken into parts
Engaged in the business means it is a regular activity, not a single favor for a friend. Effecting transactions means actually carrying out buys and sells. Securities is the subject matter. For the account of others is the broker role; for its own account is the dealer role.
The two roles inside the term map to two ways of getting paid. When the firm acts as a broker, it executes trades on a customer’s behalf and earns a commission. When it acts as a dealer, it buys and sells from its own inventory and earns a markup when it sells to a customer or a markdown when it buys from one. Most firms do both routinely, which is why the combined term broker-dealer is the one that registers.
Broker (for others)
Executes transactions on behalf of customers as an agent of the trade. The firm is a middleman, and its compensation is a commission. It is acting for someone else’s account.
Dealer (own account)
Buys and sells securities from its own inventory as a principal. Compensation is the markup on a sale or the markdown on a purchase, not a separate commission. It is acting for its own account.
Notice what the definition is built around: a firm. The individual people who work for that firm and effect transactions are agents, a separate defined term the exam keeps strictly apart from the firm. If a question describes a natural person representing the firm, that is an agent, not a broker-dealer. The companion topic, agent registration, covers that side in detail.
Who is excluded from the broker-dealer definition?
Before worrying about registration, the exam wants you to test whether a person is even a broker-dealer in the first place. Several persons are excluded from the definition outright. This is different from an exemption. An excluded person is not a broker-dealer at all, so the registration requirement simply never reaches them. An exempt person would meet the definition but be relieved of registering. State law here uses exclusions.
Agents
An agent represents a broker-dealer (or an issuer); the agent is the individual, not the firm. Agents are regulated under their own definition, so they fall outside the broker-dealer definition.
Issuers
A company selling its own securities is acting as an issuer, not as a broker-dealer. The exclusion holds unless the issuer separately takes on broker-dealer activity beyond its own offerings.
Banks, savings institutions, and trust companies
These regulated institutions are excluded from the broker-dealer definition. Watch the wording: a bank itself is excluded, but a bank holding company is not.
Out-of-state firms with no place of business
A firm with no office in the state can be excluded if it deals only with a narrow, institutional or existing-customer clientele. This is the rule the exam loves, covered next.
Being outside the broker-dealer definition removes the registration requirement, but it does not remove liability for fraud. Every excluded person is still fully subject to the antifraud provisions of state law. A bank that effects securities transactions does not register as a broker-dealer, yet it can still be pursued for fraudulent conduct.
How does the no-place-of-business exclusion work?
This is the exclusion that generates the most questions, so it is worth slowing down. A firm with no place of business in a state can fall outside that state’s broker-dealer definition, but only if it also satisfies one of two limited-clientele conditions. Both halves matter: no office in the state, and one of the two conditions below.
| Condition (need no office in the state, plus one of these) | What it covers |
|---|---|
| Institutional-only business | The firm effects transactions exclusively with or through issuers, other broker-dealers, banks, insurance companies, investment companies, large employee benefit plans, and similar financial institutions or institutional buyers. |
| Existing customer passing through | The firm is registered in its home state and deals only with an existing customer who is temporarily present in the second state and is not a resident there. |
The first condition turns on the word exclusively. If the firm has no office in the state but deals only with institutions, it stays excluded. The instant it solicits even one retail customer in that state, the exclusion collapses and registration is required.
The second condition is the snowbird rule. Picture a customer who lives in one state and spends the winter in another. A firm registered in the customer’s home state can keep serving that person while they are temporarily in the second state, as long as the firm has no office there and the customer is not a resident of that second state. It covers continuing an existing relationship, not chasing new business while the client is away from home.
There is no small-number, de minimis relief for broker-dealers. Investment advisers get limited relief when they have very few in-state clients and no office in the state, but that relief does not cross over to broker-dealers. A firm with no office that solicits a single retail customer in the state must register. Do not import the adviser rule onto the broker-dealer side.
One more boundary that fits here: registering with the SEC at the federal level does not satisfy state registration. A firm registered federally still has to register in each state where it does business. The only true federal preemption for broker-dealers in this area is the net-capital ceiling, which is up next.
What does state registration require?
Once a person does meet the definition and no exclusion applies, it is unlawful to transact business in the state as a broker-dealer without registering there. Registration is state by state. There is no single national filing that covers every state at once, and federal registration does not stand in for it.
The exam groups the requirements into a few buckets. The financial requirements are where the federal limit lives, so read that row carefully.
| Requirement | What the firm must do |
|---|---|
| Initial filing | File the uniform broker-dealer application, a consent to service of process (a one-time filing that names the state Administrator to receive legal documents), and the state’s fees. |
| Financial requirements | Maintain minimum net capital, and post a surety bond if required. The state cannot set a net-capital or bonding requirement higher than the federal minimum. |
| Recordkeeping | Make and preserve the required books and records (blotters, ledgers, customer account records, trade records, confirmations, agent records, complaint files). State authority is tied to the federal standard. |
| Ongoing filings | File financial reports as required, and promptly file a correcting amendment whenever a previously filed document becomes materially inaccurate or incomplete. |
The federal-limit ceiling on net capital and bonding
This is the most reliable single rule in the whole topic, so commit it cold. A state may require a broker-dealer to keep a minimum amount of net capital, and it may require a surety bond, which protects customers against losses from theft or misuse of their funds. What the state may not do is set either requirement higher than the federal minimum the SEC already imposes.
The rule in one line
If a broker-dealer meets the SEC’s net-capital requirement, the state has to accept it and cannot demand more. The federal minimum is the ceiling, not just a floor.
The logic is practical. A firm doing business in many states would face a patchwork of conflicting capital demands if every state could pile on its own higher figure. Capping state requirements at the federal level keeps the financial standard consistent. On the exam, any answer that has a state requiring more net capital than the SEC is wrong on its face.
For broker-dealers, bonding sits inside this financial-responsibility framework and is capped by the same federal ceiling. The bonding rules that turn on holding client funds (custody) or on discretionary authority belong to investment-adviser regulation, not to broker-dealers. If a question describes a broker-dealer and then applies a custody or discretion bonding trigger, that mismatch is the trap. The custody rule and discretion-based bonding live on the investment adviser side.
Lock In the Net-Capital Ceiling
The state-cannot-exceed-the-SEC rule shows up in several disguises on the Series 63. CertFuel's adaptive engine drills the exact wording until the federal-ceiling logic is automatic.
Choose Your PathWhat is the firm’s duty to supervise its agents?
A broker-dealer is responsible for the conduct of its people, and the exam treats supervision as its own testable obligation. The firm must establish and maintain a supervisory system reasonably designed to keep its agents and its business compliant with the securities laws.
The backbone of that system is written supervisory procedures. These are not vague policies. Good procedures name the specific person responsible for each review, state what that person reviews, set how often, and describe how the review gets documented.
What the procedures must cover
All agents, all businessSupervision of every agent and every line of business the firm runs, including the review of incoming and outgoing correspondence and a process to capture and respond to customer complaints.
The standard
Reasonable, not perfectThe firm must supervise reasonably, not flawlessly. But procedures that exist only on paper and are never enforced are no defense at all.
The point the exam drives hardest: failure to supervise is a standalone ground for action. A firm can be sanctioned for failing to reasonably supervise an agent even if the firm itself never committed the underlying violation. If an agent harms a customer and the firm had no reasonable procedure that would have caught it, the firm faces its own consequences on top of whatever happens to the agent.
- Written procedures that name who reviews what, and how often
- Actual enforcement of those procedures, with documented reviews
- Coverage of correspondence and a real customer-complaint process
- Procedures updated as the firm adds new lines of business
- Procedures that exist on paper but are never carried out
- No system to detect an agent harming a customer
- Treating supervision as optional because the firm did no wrong itself
- Reviews that are never documented, so the firm cannot show it supervised
Supervision sits next to the broader enforcement powers a state regulator holds. For how the regulator investigates, examines records, and imposes penalties, see administrator powers.
How does this topic connect to the rest of the exam?
Broker-dealer regulation does not stand alone. The agent side mirrors much of the definition-and-exclusion logic, and the way a firm sells securities ties into securities registration. Knowing the seams helps the precise wording stick.
Agent Regulation
The individual representatives of the firm have their own definition, exclusions, and registration path. Same logic, different person. See agent registration.
Securities & Issuers
How the securities a firm sells get registered, and which federal-covered securities the state cannot fully regulate. See securities registration.
Administrator Powers
The state regulator’s authority to examine, investigate, and discipline, including for the failure-to-supervise ground covered above. See administrator powers.
All of this rests on state-level securities regulation. State law here flows from the model act adopted across states, often called the Uniform Securities Act and known broadly as the blue-sky laws, administered alongside the federal framework that the SEC and FINRA oversee.
How should you study broker-dealer regulation?
Treat this topic as a decision tree, then memorize the few hard rules that anchor it. Most questions are testing whether you can run the logic in the right order and whether you remember the federal ceiling.
When a question describes a firm or person, run it in order: (1) Does it meet the broker-dealer definition (in the business of effecting securities transactions)? (2) Does an exclusion pull it out (agent, issuer, bank, or no-place-of-business)? (3) If it registers, what do the financial, recordkeeping, and filing rules require, and remember the SEC net-capital ceiling? (4) Is the firm supervising its agents reasonably with enforced written procedures?
The handful of facts to know cold: a broker-dealer is the firm and an agent is the individual; the no-place-of-business exclusion needs both no office in the state and a qualifying clientele; there is no de minimis relief for broker-dealers; a state cannot require more net capital than the SEC; and failure to supervise is its own ground for action. Once those are automatic, the fact patterns become much easier to read.
When you are ready to test yourself, work through the Series 63 practice test and the broker-dealer items in the Series 63 question bank. Active recall on these definitions beats rereading them.
A broker-dealer is a person in the business of effecting securities transactions for others (broker, earning a commission) or for its own account (dealer, earning a markup or markdown). Agents, issuers, and banks are excluded from the definition, as is an out-of-state firm with no place of business that deals only with institutions or an existing non-resident customer passing through. To register, a firm meets financial, recordkeeping, and filing requirements, but a state can never set net capital or bonding higher than the SEC minimum. The firm must reasonably supervise its agents with enforced written procedures, and failure to supervise is its own ground for action.
