What Is an RIA? What Investors Should Know

Mercer Advisors

Summary

Learn what a Registered Investment Advisor (RIA) is, how RIAs are regulated, how they differ from financial advisors, and the benefits of working with a fiduciary advisor.

An advisor working with their client on an RIA

A Registered Investment Advisor (RIA) is a firm that provides personalized investment advice and ongoing portfolio management for a fee. Advisors within these firms often serve as long-term financial partners, helping individuals and families navigate complex decisions related to investments, retirement, and overall financial planning. Their role typically extends beyond asset management to coordinated guidance across a client’s broader financial picture.

What services do RIAs provide?

The scope of services offered by an RIA can vary, but most firms take a comprehensive approach to wealth management. This often includes constructing and managing investment portfolios, developing financial and retirement plans, and coordinating strategies related to taxes and estate planning. Some advisors also bring specialized expertise in areas such as equity compensation, generational wealth transfer, or complex tax situations, depending on client needs.

Because services are defined through a formal agreement, clients have a clear understanding of what to expect from the relationship, including the level of ongoing support and guidance.

How are RIAs paid?

Compensation for advisors who work at RIAs is typically structured to promote transparency. Many advisors charge a fee based on a percentage of assets under management, while others may use flat fees, hourly rates, or project-based pricing depending on the engagement.

A key differentiator is that many RIAs operate as fiduciaries, meaning that the wealth advisors are legally obligated to act in their clients’ best interests. Advisors at fee-only RIAs are compensated directly by clients rather than through commissions, which can help minimize potential conflicts of interest.1 Understanding how an advisor is paid is an essential step in evaluating whether their incentives align with your financial goals.

Who regulates RIAs?

Regulatory oversight of RIAs is determined primarily by the amount of assets they manage. The U.S. Securities and Exchange Commission generally regulates firms overseeing $100 million or more in client assets, while state securities regulators typically govern smaller firms. Certain exceptions allow some firms to register with the SEC even if they do not meet the asset threshold, particularly for digital advisory platforms.1

Regardless of the regulator, RIAs are required to provide disclosures that outline their services, fees, and potential conflicts. Documents such as Form CRS (Customer Relationship Summary) are designed to help investors compare advisory firms and make more informed decisions.

RIAs vs. other financial advisors

The financial services industry uses a wide range of titles, many of which are not regulated. Designations, however, can provide a clearer signal of expertise. Here are three of the most common.

By contrast, the RIA designation signals that the firm or professional is registered with a governing body and subject to ongoing compliance requirements. With an RIA firm, clients typically work with licensed professionals authorized to provide advice and manage portfolios on behalf of the firm.

How to choose the right RIA

Selecting the right RIA and advisor requires careful evaluation. Investors should verify an advisor’s credentials and registration status using publicly available databases, such as those maintained by the Financial Industry Regulatory Authority (FINRA). It is also important to understand how the advisor is compensated, what services are included, and whether the advisor operates under a fiduciary standard.

Equally important is finding an advisor whose expertise aligns with your specific financial needs and whose approach fits your preferences. Taking the time to conduct due diligence can help establish a more effective and trustworthy advisory relationship.
