IAR vs RIA: The Short Answer
A registered investment adviser, or RIA, is the firm that provides investment advice, while an investment advisor representative, or IAR, is the individual who gives that advice on the firm’s behalf. The RIA registers as a business with the SEC or with a state securities regulator. The IAR registers as a person, usually with each state where they work, and is supervised by the firm.
Think of it as the company and the professional. A client signs an advisory agreement with the RIA, and the IAR is the person they meet, who builds their portfolio and answers their questions. Both are regulated, both owe the client duties, and neither can operate in the advisory business without the other.
This guide sets out exactly how the two differ, from registration and paperwork to supervision, fees and careers. For a full introduction to the individual role, start with our guide to what an investment advisor representative (IAR) is.
What a Registered Investment Adviser Is
A registered investment adviser is a firm, or occasionally a sole proprietor operating as a business, that is in the business of advising others about securities for compensation and is registered to do so. The legal definition of an investment adviser comes from the Investment Advisers Act of 1940, and state definitions follow the Uniform Securities Act. Registration is what turns an investment adviser into a registered investment adviser.
The firm is the legal counterparty to the client. It holds the advisory contract, sets the fee schedule, chooses the custodian that holds client assets, and carries regulatory responsibility for the advice given in its name. Large RIAs manage billions of dollars and employ hundreds of advisers, while the smallest are one-person practices.
Regulators spell the term adviser, and many firms use advisor in marketing. The meaning is the same. What matters is that the term describes a registered business, not a personal qualification.
What an Investment Advisor Representative Is
An investment advisor representative is an individual who, on behalf of an investment adviser, gives advice about securities, manages client accounts, decides what advice is given, solicits advisory clients, or supervises those who do. The definition looks at the work a person does rather than their job title. A wealth manager, portfolio manager or financial advisor at an RIA is usually registered as an IAR if they perform any of those functions.
IARs qualify by passing the Series 65, or the Series 66 combined with the Series 7, unless a state recognises a waiver. The registration is then filed by the firm through Form U4. Our guide to whether investment advisor representatives need the Series 65 explains when each exam applies.
FRC’s Series 65 Exam Prep is $300, or $150 a month over two months with no interest, with each chapter assessed before the next unlocks. The Series 65 needs no sponsoring firm, so candidates can prepare and sit it before joining an RIA.
How an RIA Registers
An RIA registers by filing Form ADV, and whether it files with the SEC or a state depends mainly on its regulatory assets under management. As a general rule, advisers with $100 million or more in regulatory assets register with the Securities and Exchange Commission (SEC), and smaller advisers register with the securities regulator in their home state. A buffer allows an adviser between $100 million and $110 million to choose, and requires SEC registration once it reaches $110 million.
There are exceptions on both sides. Certain advisers, such as those to registered investment companies, register with the SEC regardless of size, and some smaller advisers that would otherwise need to register in many states can register with the SEC instead. The thresholds decide which regulator examines the firm, not whether the firm is regulated.
A state-registered RIA follows its state’s rules, which are largely based on NASAA model rules and the state’s Blue Sky laws. An SEC-registered RIA follows the Advisers Act and SEC rules, and it still makes notice filings and pays fees in the states where it has clients.
How an IAR Registers
An IAR registers individually, usually with each state where they have a place of business, through a Form U4 filed by the RIA. The filing passes through the Central Registration Depository and the Investment Adviser Registration Depository. The individual cannot file their own IAR registration.
That rule holds even when the firm is registered with the SEC. Federal law leaves the registration of individual advisers largely to the states, so an IAR of an SEC-registered firm with a place of business in a state will typically register in that state. The firm and the person can therefore be regulated by different authorities.
When an IAR changes firms, the old RIA files a Form U5 and the new RIA files a fresh Form U4. A passed Series 65 stays valid for two years without registration, so an IAR who takes a break has a window to return without requalifying.
The Paperwork Each One Files
The RIA files Form ADV, which has two main parts relevant to clients. Part 1 gives regulators data about the firm, its ownership, its assets and its disciplinary history. Part 2A, the firm brochure, explains in plain English the firm’s services, fees, conflicts of interest and investment approach.
The IAR appears in Form ADV Part 2B, the brochure supplement. It describes each individual adviser who works with a client, including their education, business background, disciplinary history, other business activities and who supervises them. Clients receive the supplement for each adviser who provides advice to them.
Many RIAs that serve retail investors also deliver Form CRS, a short relationship summary covering services, fees, conflicts and standard of conduct. Form ADV must be updated at least once a year within 90 days of the firm’s fiscal year end, which for most firms falls in the first quarter.
Who Owes the Fiduciary Duty?
Both the RIA and the IAR owe clients a fiduciary duty, made up of a duty of care and a duty of loyalty. The firm owes the duty as the adviser, and the IAR acts as the firm’s agent in delivering advice that meets it. In practice, the IAR is the person who puts the duty into effect at every client meeting.
The duty of care means advice that fits each client’s objectives and circumstances, based on a reasonable inquiry, along with seeking best execution and monitoring the account where agreed. The duty of loyalty means disclosing material facts and conflicts fully and fairly, so the client can give informed consent. Our explainer on the difference between a fiduciary standard and a suitability standard compares this with the broker standard.
When an IAR breaches the duty, both can face consequences. Regulators can sanction the individual and the firm, and the firm can be held responsible for failing to supervise. Our guide to what the Investment Advisers Act of 1940 requires in practice covers the obligations in depth.
Compliance Duties Belong to the Firm
The RIA carries the compliance programme, and the IAR works within it. Under SEC Rule 206(4)-7, an SEC-registered adviser must adopt written compliance policies, review them at least annually and appoint a chief compliance officer. State rules impose similar expectations on state-registered firms.
The firm also keeps the books and records required by SEC Rule 204-2, maintains a code of ethics covering personal trading, and follows the marketing rule under SEC Rule 206(4)-1 for advertisements and testimonials. These are firm-level obligations, even though IARs generate much of the activity they govern.
For the IAR, compliance means following the firm’s procedures. That includes reporting personal trades, getting marketing materials approved, documenting client suitability information under Know Your Customer (KYC) processes, and disclosing outside business activities.
Can an Individual Be an RIA?
An individual can own and operate an RIA, and in that case they are both the firm and its IAR. A solo adviser forms a business, registers it as an investment adviser and is registered as that firm’s representative. The two registrations still exist separately, even when one person holds both roles.
What an individual should not do is present “RIA” as a personal credential. RIA describes a registered firm, not a qualification earned by a person, and regulators have cautioned that using it after a name can suggest a credential that does not exist. The accurate way for a person to describe themselves is as an investment adviser representative of a named registered investment adviser.
This distinction matters to clients. A client who wants to check an adviser should look up both the individual and the firm, since each has its own record.
IAR vs RIA vs Registered Representative
A third role often enters the comparison: the registered representative of a broker-dealer. A registered representative executes securities transactions and is regulated by FINRA, typically earning commissions. When recommending securities to retail customers, registered representatives follow Regulation Best Interest rather than the adviser’s fiduciary standard.
Many firms are dual registrants, registered as both an RIA and a broker-dealer, and many professionals are registered as both an IAR and a registered representative. They can offer fee-based advisory accounts and commission-based brokerage accounts, but they must be clear with each client about which capacity they are acting in.
The records differ too. Broker-dealers and registered representatives appear on BrokerCheck, while RIAs and IARs appear in the SEC’s Investment Adviser Public Disclosure records, which BrokerCheck links to.
How Fees Flow Between the RIA and the IAR
The client pays the RIA, and the RIA pays the IAR. Advisory fees are usually a percentage of assets under management, although flat fees, hourly fees and retainers are also common. The fee schedule is set by the firm and disclosed in Form ADV Part 2A.
How the IAR is paid depends on the firm’s model. Some IARs earn a salary with bonuses, some receive a share of the revenue from the clients they serve, and owners of their own RIA keep the profit after costs. The firm must disclose any compensation arrangements that create conflicts of interest.
That structure is part of what makes the advisory model attractive to clients. Fees tied to assets align the adviser’s income with the growth of the client’s portfolio. Our Complete Guide to Financial Advisory USA covers pay across the profession.
Career Paths: From IAR to RIA Owner
Most advisory careers begin as an IAR at an established firm and some end with ownership of an RIA. Early-career IARs often start as associate advisers or in client service, learning financial planning and portfolio work under experienced colleagues. Over time they build their own client relationships and take on more responsibility.
Some IARs stay at large firms and rise into senior roles in wealth management or practice leadership. Others leave to found their own RIA, taking on the firm’s compliance, registration and business costs in exchange for independence and a larger share of the fees. Both paths start with the same exam and the same individual registration.
Our Investment Advisor Representative Pathway shows how the stages connect, and how to become an investment adviser representative covers each step from first study session to registration.
Which Should You Aim For First?
If you are starting a career, you aim to become an IAR first, because an RIA is a business you might build or join later. The first practical step is the Series 65, followed by securing a role with an advisory firm that will register you. Our guide to how much a Series 65 course costs sets out the budget.
Some roles also ask for the Series 63, particularly where the firm also operates as a broker-dealer. The Series 63 course is $300 with its own $147 exam fee. Check what your target firm expects before you buy more than you need.
From January 4, 2027, NASAA shortens the Series 65 retake wait after a third failed attempt from 180 days to 60, for exam windows opened on or after that date. Our guide to the Series 65 rule change explains how it works.
How Clients Check an IAR and an RIA
Clients can check both the firm and the individual through the SEC’s Investment Adviser Public Disclosure records. A search on the firm shows its Form ADV, including the brochure, registration status and any disciplinary history. A search on the individual shows their registrations, employment history, exams passed and any disclosures.
Checking both is the sensible approach, because each record tells a different part of the story. A firm with a clean record may employ an adviser with past issues, and a strong individual adviser may work for a firm with regulatory history of its own. Reading the Form ADV Part 2A brochure and the Part 2B supplement together gives the full picture.
For anyone preparing to become an IAR, it helps to know your own record will be public from the day you register. Clients, employers and regulators will all see your registration history. That transparency is one reason firms value candidates who show steady, verifiable progress before they join.

Work through the entries linked here, from registered investment advisor to Regulation Best Interest, to test whether you can explain the differences clearly. That skill is exactly what the Series 65 examines.
The regulatory entries are especially useful. SEC Rule 206(4)-7, SEC Rule 204-2 and SEC Rule 206(4)-1 together describe much of an RIA’s compliance framework. Understanding them shows an employer you already know how an advisory firm operates.
Short daily sessions with quizzes fit easily around a full-time job. They also make the legal sections of the exam far less intimidating.
Making Your Preparation Visible to RIAs
FRC’s Digital Profile shows the courses you are actively studying, the chapters you have completed and your real-time assessed progress, verified by FRC. With Professional Membership, a QR code on your resume takes a hiring manager straight to that profile. An RIA considering you can see your Series 65 preparation under way and how far it has gone.
Advisory firms hire for trust as much as knowledge. The FRC Video Resume shows how you communicate before anyone meets you, which is the quality clients notice first in an adviser. Our guides to how the FRC Video Resume works and get seen before you get interviewed explain where it fits.
The Professional Membership page has the full detail at $39.99 a month. The full list of FRC courses for USA candidates shows every programme, and the membership and deals page lists combined pricing, paid in full.
The Firm and the Professional
The RIA is the registered firm that holds the client relationship, carries the compliance programme and files Form ADV. The IAR is the registered individual who delivers advice, appears in Form ADV Part 2B and puts the fiduciary duty into practice. One cannot work without the other.
For anyone entering the profession, the route runs through the IAR registration first. Our guides to what an investment advisor representative does and why you would build a career as an investment advisor representative show where that first registration can lead.
