The investment adviser de minimis exemption lets an adviser skip state registration in any state where the adviser has no office and has served five or fewer resident clients during the prior 12 months. It comes from Section 222(d) of the Investment Advisers Act of 1940, which sets a nationwide floor: states can be more lenient, but none can force an out-of-state adviser to register below that threshold. For a solo practitioner or small firm picking up clients across state lines, the exemption is often the difference between one registration and a dozen.
The Five-Client Rule in Practice
The count is simple to state and easy to get wrong. If you have no place of business in a state and five or fewer of that state’s residents have been your clients at any point during the last 12 months, you do not have to register there.1Securities and Exchange Commission. Final Rule: Exemption for Certain Investment Advisers Operating Through the Internet – Section: 1. Regulatory Baseline The moment a sixth client in that state signs on, the exemption is gone and you must already be registered before you provide advisory services to that person.
The 12 months is a rolling window, not a calendar year. Count backward from today and include every client who resided in the state at any point during that stretch, including clients you have since terminated. Someone you advised from March through August still counts against any 12-month window that touches those months. That makes your status a moving target, so a running client-by-state log matters more than an annual review.
There is no grace period built into the rule. You cannot take on the sixth client and register afterward. Because state processing commonly runs 30 to 45 days, the working practice is to start the registration paperwork when you reach three or four clients in a state, so you are ready before a sixth prospect arrives. Waiting until you have five clients and a warm lead usually forces a choice between turning away the business or advising while unregistered.
Who Counts as a Client
The counting rules do heavy lifting, because they decide whether you stay under five. The SEC points advisers to Rule 202(a)(30)-1, which groups certain related persons into a single client.2eCFR. 17 CFR 275.222-2 Definition of Client for Purposes of the National De Minimis Standard A natural person, that person’s spouse, and relatives sharing the same home count as one client. A corporation, partnership, or trust also counts as one client when the advice is tailored to the entity’s investment objectives rather than to those of its individual owners.
Some clients are excluded from the count entirely because regulators treat them as capable of protecting themselves. The main exclusions are institutional:
- Registered investment companies, such as mutual funds already subject to their own regulation.
- Insurance companies and banks, which have their own compliance infrastructure.
- Employee benefit plans with substantial assets, overseen by ERISA fiduciaries.
The practical effect: an adviser could serve three retail clients and several institutional clients in a state and still qualify for the exemption, because the institutional relationships do not enter the calculation.1Securities and Exchange Commission. Final Rule: Exemption for Certain Investment Advisers Operating Through the Internet – Section: 1. Regulatory Baseline
The Place-of-Business Condition
The client count is only one of two conditions. The other is that you have no place of business in the state. If you do, the client count stops mattering and you must register regardless of how few clients you have.
The SEC defines a place of business as an office where an adviser representative regularly provides advisory services, meets with clients, or communicates with them, plus any location held out to the public as a place where advisory services are offered.3eCFR. 17 CFR 275.203A-3 Definitions A dedicated office qualifies. A co-working space where you routinely meet local clients likely does too. Unlike the client count, this test has no threshold to sit under. Opening a satellite office in a new state means immediate registration there, even with zero clients in the state yet.
What Still Applies When You Are Exempt
Being exempt from registration is not the same as being unregulated, and this is where advisers relying on the exemption most often misread the law. Section 206 of the Investment Advisers Act prohibits fraud and deception by “any investment adviser,” registered or not.4Office of the Law Revision Counsel. 15 U.S. Code 80b-6 – Prohibited Transactions by Investment Advisers Congress broadened that language in 1960 by removing a reference to registered advisers, so the anti-fraud reach now covers every person who meets the statutory definition of an investment adviser.
In practice, an adviser operating under a de minimis exemption still owes fiduciary duties, must disclose conflicts of interest, cannot self-deal without informed consent, and cannot misrepresent qualifications or performance. State anti-fraud statutes generally impose similar duties. The exemption removes the paperwork and fees; it does not touch the substantive rules on how you treat clients.
Where the Exemption Fits: SEC vs. State Registration
The de minimis rule matters most to advisers who register with states rather than the SEC, because those are the advisers who might otherwise have to register in several states as clients spread out. The federal-state split runs by assets under management:
- Below $100 million in AUM: state registration, generally in your home state and in any state where you have a place of business or exceed the de minimis threshold.
- Between $100 million and $110 million: you can choose SEC or state registration. This buffer prevents ping-ponging as assets move.
- $110 million or more: SEC registration is required, and you become a federal covered adviser.5eCFR. 17 CFR 275.203A-1 Eligibility for SEC Registration; Switching to or From SEC Registration
An SEC-registered adviser does not have to switch to state registration until AUM drops below $90 million, giving another cushion against short-term swings.5eCFR. 17 CFR 275.203A-1 Eligibility for SEC Registration; Switching to or From SEC Registration Once a firm is federally registered, most state registration requirements are preempted; the firm still owes notice filings and fees to states where it does business, but not full state registration.
A separate de minimis framework applies to advisers based outside the United States (the foreign private adviser exemption), and it is not the same rule. That exemption uses its own client count, a $25 million U.S. AUM cap, and a no-public-marketing condition.6U.S. Securities and Exchange Commission. Regulation of Investment Advisers by the U.S. Securities and Exchange Commission – Section: 3. Foreign Private Advisers If you are a domestic adviser thinking about state registration, the foreign framework is not the one you rely on.
When You Cross the Threshold
Losing the exemption is an operational bottleneck more than a legal abstraction. When a sixth client appears (or you open an office in the state), you need to be registered before providing advisory services. State registration generally means filing Form ADV through the Investment Adviser Registration Depository, paying a filing fee, and waiting on the state to process the application. Firm filing fees commonly range from about $50 to $500, with separate fees for individual adviser representatives.
Registration is not one-and-done. Most states require annual renewal filings and fees. If your client count in a state later falls back below six, check that state’s rules before assuming you can drop registration; some states let you withdraw and return to de minimis status, while others expect you to stay registered once you have registered.
Consequences of Getting It Wrong
Advising in a state where you should have registered but did not carries real exposure. The SEC can censure an adviser, suspend a registration for up to 12 months, revoke it, or deny future applications based on the same conduct.7Office of the Law Revision Counsel. 15 U.S. Code 80b-3 – Registration of Investment Advisers State regulators have parallel tools.
On the civil side, clients who received advice from an unregistered adviser may have rescission rights, meaning they can unwind the advisory relationship and recover fees paid plus interest.8U.S. Securities and Exchange Commission. Consequences of Noncompliance Contracts entered into in violation of registration requirements are potentially voidable, so the adviser may have done the work with no enforceable claim to compensation. A single rescission demand can be financially serious for a small firm.
The reputational tail is often the longest problem. A registration violation can trigger bad-actor disqualifications that limit participation in Regulation D private offerings, and future clients and institutional investors routinely review an adviser’s regulatory history. A settled enforcement action still shows up in due diligence years later.
