In finance, RIA stands for Registered Investment Adviser: a firm (or individual) that is paid to give advice about securities and is registered with the U.S. Securities and Exchange Commission or a state securities regulator. An RIA owes the people it advises a fiduciary duty under the Investment Advisers Act of 1940, which means a duty of care and a duty of loyalty for the whole advisory relationship. “Fee-only” is a description, not a separate registration category; it describes an RIA that is paid only by the families it serves, with no commissions from products it recommends.
For a two-income household in the Bay Area or Seattle with RSUs, a 401(k) at work and young kids, the label matters for one practical reason. It tells you what legal standard the person across the table is held to, and where to look up how they are paid.
What “registered” does and does not mean
Registration is a filing, not a credential. The SEC’s own Form ADV instructions require an adviser that calls itself “registered” to state that registration does not imply a certain level of skill or training. It means the firm is on the regulator’s books, files public disclosures, and can be examined.
Which regulator a firm registers with depends mostly on size. Under SEC Rule 203A-1, a mid-sized adviser may register with the SEC once it has at least $100,000,000 of assets under management, and generally must register with the SEC at $110,000,000. Smaller firms register with their home state: the Department of Financial Protection and Innovation in California, or the Department of Financial Institutions, Securities Division in Washington. Both kinds are RIAs and both owe the same basic fiduciary duty.
The fiduciary duty, in plain terms
The SEC set out the standard in its 2019 interpretation of the standard of conduct for investment advisers (Release IA-5248). An adviser’s fiduciary duty “comprises a duty of care and a duty of loyalty.” In practice:
- Care: advice has to fit your goals and situation, with reasonable research behind it, and when the adviser chooses the broker for your trades it has to seek best execution.
- Loyalty: the adviser cannot put its own interest ahead of yours. It must “eliminate or at least expose through full and fair disclosure” every conflict of interest that could sway its advice.
Note the second half. A fiduciary can still have conflicts, as long as they are disclosed and you consent. Being an RIA lowers the odds of a hidden incentive. It does not remove the need to read how the firm is paid.
RIA, broker and “dually registered”: the distinction that trips people up
A broker-dealer representative sells securities and is paid mainly through commissions. Brokers follow the SEC’s Regulation Best Interest when they make a recommendation, which is a different rule from the adviser fiduciary duty. Many large firms are both, and many individual professionals hold both licenses. The same person can act as a fiduciary adviser on one account and as a broker on another, such as when selling an annuity or insurance policy.
That is why “my adviser works at an RIA” is not the whole answer. The question to ask is: in which capacity are you acting on this specific recommendation, and how are you paid for it? Our comparison of wirehouses and broker-dealers walks through how each model is structured, and what share of advisers are fiduciaries covers how common each setup is.
Worked example: what the fee structure means for a $1.2M household
Assumptions, for illustration only: a married couple in Sunnyvale, California, with $1,200,000 of combined W-2 income, two kids aged 4 and 7, $3,000,000 in a taxable brokerage account, $900,000 in 401(k)s, and RSUs vesting each quarter. The fee levels below are hypothetical round numbers chosen to show the arithmetic, not market averages.
| How the adviser is paid | Annual cost on these assumptions | What to check |
|---|---|---|
| Fee-only RIA, 1% of the $3,000,000 it manages | $30,000 | Whether the 401(k)s, RSUs and equity plan are covered, or ignored because they are held away |
| Fee-only RIA, flat annual fee of $24,000 | $24,000 | What is included: tax planning, RSU sale timing, estate coordination |
| Commission-based broker | No visible advisory fee | Commissions and fund expenses inside each product, shown in the firm’s disclosures |
Two points stand out. First, an asset-based fee grows with the account even if the work does not: on the same 1%, a $5,000,000 account costs $50,000 a year. Second, the account an asset-based fee covers is often the least complicated part of this family’s money. The hard decisions sit in the RSUs, the 401(k) options, withholding and the estate documents for the kids. A fee that only reaches the brokerage account can leave those unmanaged. Our guide to RIA fees goes deeper on comparing pricing.
How advisory fees are treated for tax in California and Washington
This is the “RIA tax treatment” question families ask most. Federally, investment advisory fees paid from a taxable account are not deductible: IRS Publication 529 lists “investment fees and expenses” among the miscellaneous itemized deductions you generally can no longer claim.
California does not follow that rule. The FTB’s Schedule CA (540) instructions state that the federal deduction for miscellaneous itemized deductions subject to the 2% floor is suspended, and “California law does not conform.” So a California family can include investment advisory fees on the state return, to the extent all such expenses exceed 2% of adjusted gross income.
In the example above, treating the couple’s adjusted gross income as about $1,200,000 (an assumption; investment income would push it higher), 2% is $24,000. A $30,000 fee leaves $6,000 above the floor. If the couple’s California taxable income is roughly $1,150,000, their 2025 marginal state rate is 11.3% plus the 1% Behavioral Health Services Tax on taxable income over $1,000,000, or 12.3%. The deduction is worth at most about $738 (12.3% of $6,000), and California’s limit on itemized deductions at high incomes can reduce it further. Small, but real, and easy to miss if nobody asks for the fee invoice at tax time.
Washington has no individual income tax in 2026, so there is no state deduction to claim. The state has enacted a 9.9% income tax on adjusted gross income over $1,000,000 starting January 1, 2028, according to the Washington Department of Revenue; how it will treat investment expenses is still pending guidance.

How to check an RIA in about 20 minutes
- Search the firm and the person on the SEC’s Investment Adviser Public Disclosure site. It shows registration, disciplinary history and the firm’s filings.
- Read Form CRS. SEC-registered advisers and broker-dealers that serve individual (retail) investors must give you this short relationship summary covering services, fees and conflicts in plain English.
- Read Form ADV Part 2A (the brochure), especially the fee and conflicts sections. Look for revenue sharing, proprietary funds and any affiliated broker or insurance agency.
- Ask in writing: Are you acting as a fiduciary on every account and every recommendation? Do you or anyone at your firm receive commissions? What does my fee cover beyond the accounts you hold?
The answers belong in the same place as the decision itself. For how we think about who manages what, see our investment and risk management page.
What to document for your kids
Choosing an adviser is one of the decisions your children will inherit without the reasoning. Write one page: why you chose an RIA, how the firm is paid, what you checked, and what would make you change. When your kids are adults, that page tells them how to evaluate the person managing the money, not just who it is. As Kevin Luu, Co-Founder and Chief Learning Officer of Bright Advisers, puts it: “Your kids don’t need to inherit your portfolio. They need to inherit your decision-making process.” Our family governance work is built around writing those pages down in a FamilyKnowledge® Library.
Frequently asked questions
Is every financial adviser an RIA?
No. “Financial adviser” is a loose job title. Some advisers work for or own an RIA; some are broker representatives; many are both. The only reliable way to know which role someone is in is to look them up on the SEC’s public disclosure site and read their Form CRS, then ask which capacity applies to each account.
What does “family RIA” mean?
People use it two ways. Sometimes it means an RIA that focuses on families and coordinates tax, estate, education and investment decisions in one place. Sometimes it means a family office that registered as an RIA. Either way, the same rules apply: registration, Form ADV disclosures and a fiduciary duty to the people it advises.
Does a fee-only RIA mean no conflicts at all?
No. Removing commissions removes one large conflict, but others remain. An asset-based fee rewards keeping money in managed accounts rather than paying down a mortgage or funding a 401(k) the firm does not manage. A good fee-only adviser names those conflicts in Form ADV and talks you through them.
