Is an RIA the same as a broker-dealer?
An RIA and a broker-dealer are two different kinds of financial firms, regulated under two different laws. A Registered Investment Adviser, or RIA, is registered under the Investment Advisers Act of 1940. RIAs give advice for a fee and owe clients a fiduciary duty. A broker-dealer is registered under the Securities Exchange Act of 1934. Broker-dealers sell securities to clients and follow Reg BI, a 2020 rule that says broker calls must be in the client's best interest at the time of the call. Reg BI is not the same as a fiduciary duty. A broker can earn commissions, 12b-1 trails, and product sponsor revenue. An RIA charges fees billed to the client. Many big firms run both an RIA arm and a broker-dealer arm under one brand. That is a "dual-registered" or "hybrid" firm, and it is where most consumer confusion happens.
Side by side
| RIA | Broker-Dealer | |
|---|---|---|
| Federal law | Advisers Act of 1940 | Exchange Act of 1934 |
| Pays the firm | Client fees | Commissions and trails |
| Standard | Fiduciary | Reg BI ("best interest" at the time) |
| Disclosure form | Form ADV | Form CRS, plus FINRA filings |
| Regulator | SEC or state | FINRA + SEC |
How to tell which kind you are dealing with
Read Form CRS. Every retail-facing firm must give you one. The first page lists, in plain English, whether the relationship is brokerage, advisory, or both. If you cannot find your Form CRS, search the firm at adviserinfo.sec.gov and at brokercheck.finra.org. If the firm shows up at both, you are dealing with a hybrid.
What it means for cost
An RIA's fee is on your statement. You can see every dollar. A broker-dealer's commissions are baked into the products. The cost is real, but it shows up inside fund expense ratios, annuity loads, and product trails. The all-in cost can be very different from the headline.
What it means for the relationship
An RIA's duty is ongoing. The advisor must keep watching your situation and adjust over time. A broker-dealer's duty under Reg BI is at the moment of the call. The broker can sell you a product, walk away, and have no further duty until the next call. That gap matters most over decades, when small differences in attention compound.
How to pick
If you want advice and ongoing care, you want an RIA. If you only want execution — buying and selling at the cheapest price — a discount broker is fine. The trouble starts when a broker-dealer rep gives ongoing advice without the matching duty. Reading the firm's Form CRS up front avoids most of that trouble.
