Fiduciary vs. Broker-Dealer vs. Financial Planner: What the Titles Actually Mean
Three titles you will meet on the approach to retirement. Only one of them is a legal standard. Here is what each one obliges the person across the table to do, and how to tell which one you are talking to.
What does a fiduciary financial advisor do differently than a broker-dealer or a financial planner?
A fiduciary adviser is bound by the Investment Advisers Act to put your interest ahead of their own across the entire relationship, with duties of care and loyalty, ongoing advice where the engagement is ongoing, and full disclosure of conflicts. A broker-dealer representative is held to Regulation Best Interest, which requires acting in your best interest at the time a recommendation is made but carries no ongoing duty. Financial planner is a job description, not a regulated title: a planner may be either of the first two, or neither. The way to know which one you have is registration, not the business card.
Who comes first, and for how long.
Three standards govern financial professionals in the United States, and they are not equal.
The fiduciary standard under the Investment Advisers Act of 1940 requires a registered investment adviser to serve the client's best interest at all times. The SEC has interpreted that duty as broad: it applies to the whole adviser-client relationship, it comprises a duty of care and a duty of loyalty, and it requires the adviser to eliminate conflicts of interest or disclose them fully enough that the client can give informed consent.
Regulation Best Interest, in force since June 2020, governs broker-dealers and their representatives. It replaced the older suitability rule for retail customers and is substantially stronger than it: a recommendation must be in the customer's best interest, conflicts must be disclosed and in some cases mitigated, and the firm's interest cannot be placed ahead of the customer's. What it does not do is impose an ongoing duty. The obligation attaches to the recommendation, not to the relationship.
Financial planner is neither. It has no definition under federal securities law. Some planners are registered investment advisers and therefore fiduciaries; some are broker-dealer representatives under Reg BI; some hold both registrations and switch roles by account; some hold neither. For the decisions on the approach to retirement, which are largely permanent, the difference between a duty that lasts and a duty that attaches to one transaction is the thing to settle first.
What each one is, and what each one owes you.
Same kitchen table, three different obligations.
| Question | Fiduciary adviser (RIA) | Broker-dealer representative | Financial planner |
|---|---|---|---|
| Legal source | Investment Advisers Act of 1940 | Securities Exchange Act of 1934; Regulation Best Interest | None attached to the title |
| Standard | Fiduciary duty of care and loyalty, across the relationship | Best interest at the time of a recommendation; disclose and mitigate conflicts | Whatever their registration imposes, if any |
| Ongoing duty | Yes, including monitoring where the engagement is ongoing | No general duty to revisit a past recommendation | Depends on registration |
| Typically paid by | Client fees (fee-only) or fees plus commissions (fee-based) | Commissions and other product-related compensation | Any of the above |
| Disclosure document | Form ADV Parts 2A and 2B | Form CRS and product disclosures | Depends on registration |
| Regulator | SEC or state securities regulator | FINRA and the SEC | Depends on registration; designations are enforced by their issuing body |
The fiduciary adviser
The duty of loyalty means the adviser cannot place its own interest ahead of yours and must disclose every material conflict. The duty of care means advice based on a reasonable understanding of your objectives, best execution of transactions, and ongoing advice and monitoring where the engagement is ongoing. Independent advisers are not limited to a firm's product list and can recommend any investment that serves the plan. Compensation is disclosed in Item 5 of Form ADV Part 2A; the individuals who will actually advise you are in Part 2B.
The broker-dealer representative
A broker-dealer facilitates securities transactions and is regulated by FINRA. Regulation Best Interest has four parts: a disclosure obligation (relationship, fees and conflicts, in writing, at or before the recommendation), a care obligation (a reasonable basis to believe the recommendation is in your best interest), a conflict obligation (policies to identify, disclose and mitigate conflicts), and a compliance obligation. It is a real standard and a representative who follows it is doing careful work. The distinction that matters most is timing: it applies when the recommendation is made and does not oblige anyone to revisit it as your circumstances change.
The financial planner
An industry term for someone who looks at the whole picture: income, taxes, investments, insurance, estate. The title alone tells you nothing about the legal standard. Ask what registration the person holds, in what capacity they are serving you for each service, and whether they will confirm fiduciary status in writing. Then verify the registration yourself.
When the same person is two of the three.
Many professionals at large firms hold both registrations. The standard that applies depends on which role they are in.
A professional can be registered as a broker-dealer representative and as an investment adviser representative at the same time. On an advisory account, the fiduciary duty applies. On a brokerage account, Regulation Best Interest applies. Which capacity governs a given interaction is a question of facts and circumstances: the type of account, how it was described to you, how the person is compensated for it, and whether they made the capacity clear. The firm's Form CRS lists the capacities it offers. The question to ask, for each service, is: in what capacity are you serving me here, and what standard applies? If the answer is unclear, that is the information you came for.
Where the difference shows up on the approach to retirement.
Four decisions you make once.
- The 401(k) rollover: a recommendation to move assets to where an adviser can be paid on them deserves the analysis behind it, in writing, under either standard
- Social Security claiming: permanent, and for a couple it sets the survivor's income for life; it produces no product, so a transaction-based model has no financial reason to spend hours on it
- The income product: an annuity can fill a real gap, and the question is whether the gap was measured first or the product came first
- Ongoing review: a plan built at 62 has to be revisited at 65 and 70; only one of the three standards obliges anyone to do that
For households in Hudson and across southern New Hampshire, the search for a financial advisor usually comes down to this question in practical form: who is obliged to still be paying attention in year five? Hudson sits on the Merrimack between Nashua and the Massachusetts line, with many of its pre-retirees commuting into Massachusetts or holding a pension from a Massachusetts employer, which adds a two-state tax question to every withdrawal decision. KBR Retirement & Investment Solutions serves Hudson households from Londonderry, about twenty minutes east on Route 102, and by video, with retirement planning and retirement income planning handled by one fiduciary adviser from the first meeting on.
Credentials, verification, and the questions to ask.
Registration is what you can enforce. Everything else is a second check.
The SEC's Investment Adviser Public Disclosure site at adviserinfo.sec.gov holds every registered adviser's Form ADV, including compensation, conflicts, disciplinary history and the individuals who advise clients. FINRA BrokerCheck covers broker-dealer representatives. Both are free and both show whether a person holds one registration or two. Professional designations do not appear in either; some impose a fiduciary obligation on their holders when giving financial advice, enforced by the issuing organization, and are verified with that organization directly.
Then ask five questions and get the answers in writing: Are you a fiduciary at all times, for every service? How are you and any affiliate compensated? In what capacity are you serving me on each account? What is my total cost as a single number? Who will I actually work with over time? If the written answers and the spoken ones differ, keep looking.

Common questions.
Are all financial advisors fiduciaries?
No. The title financial advisor is not regulated, so it tells you nothing about the standard. An investment adviser representative of a registered investment adviser owes a fiduciary duty across the whole relationship under the Investment Advisers Act. A broker-dealer representative is held to Regulation Best Interest at the time of a recommendation. Many professionals are registered as both and switch capacities by account. Ask which capacity applies to each service, and get fiduciary status in writing.
What is the difference between fee-only and fee-based advisors?
Fee-only means the adviser is paid only by the client, through a percentage of assets, a flat fee, an hourly rate or a retainer, with no commissions or product payments. Fee-based means client fees plus possible commissions. The terms sound alike and are structurally different. Confirm which applies in Item 5 of the firm's Form ADV Part 2A, and ask separately whether the person is a fiduciary at all times.
Can a broker-dealer also be a fiduciary?
A broker-dealer representative acting as a broker is held to Regulation Best Interest, not the Advisers Act fiduciary duty. But many representatives are dually registered as investment adviser representatives, and in that capacity they owe a fiduciary duty on advisory accounts. Which standard applies depends on the role the person is acting in for a given account or recommendation. The firm's Form CRS says which capacities it offers; ask which one applies to you.
How do I verify if my advisor is a fiduciary?
Search the person and the firm on the SEC's Investment Adviser Public Disclosure site. If they appear as an investment adviser representative, a fiduciary duty applies to the advisory relationship; read Form ADV Part 2A for compensation and conflicts and Part 2B for the individuals who advise you. Search FINRA BrokerCheck as well; if the same person appears as a securities representative, ask which role applies to each account. Then ask for fiduciary status in the advisory agreement.
Does a financial planner have to act as a fiduciary?
Not by virtue of the title. Financial planner has no definition under federal securities law, so a planner may be a registered investment adviser (fiduciary), a broker-dealer representative (Regulation Best Interest), or neither. Some professional designations impose their own fiduciary obligation on holders when giving financial advice, which is enforced by the issuing organization rather than by a regulator. Ask what registration the person holds and verify it; the designation is a second check, not a substitute.
