De Minimis Exemption

Quick Answer
The de minimis exemption allows an investment adviser to avoid registering in a particular state if the firm has fewer than a specified number of clients residing there — commonly five or fewer, though exact thresholds and rules vary by state.

What Is the De Minimis Exemption for Investment Advisers?

The De Minimis exemption exists to spare advisers from the burden of registering in every state where they happen to have one or two incidental clients, often the result of a client relocating rather than active solicitation in that state. Firms relying on the de minimis exemption still need to track their client count by state carefully, since exceeding the threshold, even by gaining a single additional client in a given state, can trigger a registration requirement there.

Some states apply the de minimis exemption differently or have their own specific thresholds and conditions, so firms operating near the edge of the standard threshold in any state should confirm that state’s exact rule rather than assuming a uniform national standard.

Why it Matters

Firms relying on this exemption need an active system for tracking client counts by state, since crossing the threshold without noticing is a straightforward way to end up unregistered in a state where registration has become required.

Frequently Asked Questions

What's the typical de minimis threshold?

Often five or fewer clients in a state, though this varies and should be confirmed for each specific state.

Does the de minimis exemption apply to SEC-registered advisers too?

The exemption specifically concerns state registration; SEC-registered advisers instead deal with notice filing obligations in states where they have clients.
