Phase 02: Form

Registering Your RIA: State Thresholds, Notice Filings, and Sequencing

8 min readUpdated April 2026

The mechanics of Form ADV, Part 1 versus Part 2, and the Series 65 exam are covered in depth elsewhere in this guide series. What trips up otherwise well-prepared founders is sequencing: registering before confirming the current threshold that governs SEC-versus-state registration, misunderstanding what a notice filing actually requires once you have clients in more than one state, and picking a registered agent and formation state without thinking through what that choice locks in.

Your State's Threshold Isn't a Number You Should Assume You Know

Whether you register with the SEC or with your state depends on an AUM threshold set by rule, and rules like this are revisited over time — the number you remember from an article you read a year or two ago may not be the number that applies when you actually file. Before you build a registration timeline or a compliance budget around a specific threshold, confirm the current figure directly against NASAA and SEC guidance. This isn't a formality: the SEC and state paths have different exam bodies, different ongoing obligations, and different timelines, so getting this wrong early can cost you weeks of rework later. If your projected first-year AUM sits anywhere near the boundary either way, plan for the possibility that you'll need to switch paths after your first year, and ask your compliance consultant what that transition actually involves before it becomes a live deadline.

Notice Filing Isn't the Same as Registering Again

Once you're properly registered — whether with the SEC or with your home state — most other states where you pick up clients require only a notice filing, not a full separate registration process. A notice filing is materially lighter: it typically means submitting your existing Form ADV and a fee to that state rather than undergoing a second review of your firm from scratch. The specific rules for which states require a notice filing, at what client or presence threshold, and what fee applies vary by state, so confirm each one individually rather than assuming every state you'll serve clients in works the same way as your home state. This matters most for advisors building a niche practice, since a genuinely national or remote-friendly niche can put you in notice-filing territory in far more states, far sooner, than a locally focused practice would.

Choosing a Registered Agent and Formation State

Every LLC needs a registered agent — a person or service with a physical address in the formation state who can receive legal and state correspondence on the entity's behalf. If you have a stable business address in your formation state, you can often serve as your own registered agent; if you don't, or if you're forming in a different state than where you'll actually be based, a registered agent service fills that role. This is a small, mechanical decision on paper, but it's worth making deliberately rather than defaulting to whatever your entity-formation service bundles in, because your registered agent's address becomes part of your public entity record. Most solo advisors are best served forming in the state where they actually live and work rather than a state known for favorable corporate law — the tax and multi-state filing complexity that comes with forming out-of-state rarely pays off for a single-advisor practice.

Your Principal Office Does More Than Set Your Commute

One decision that gets made almost incidentally during registration — where you designate your principal office and place of business — has legal consequences well beyond convenience. Under the Investment Advisers Act, the state where your principal office sits can determine which state's net-worth and bonding rules apply to you, even for business you conduct in other states. This is covered in depth in our Location guide; the point to flag here is that it belongs in your registration planning, not as an afterthought you address once you've already filed.

What Goes Wrong When You Register Before You're Ready

A common pattern: an advisor files Form ADV to hit a self-imposed launch date, then discovers the policies and procedures manual doesn't match the operation described in the filing, the custodian relationship isn't actually confirmed yet, or the entity and bank account weren't fully separated before the filing went in. None of these are catastrophic on their own, but they create rework during your registration review — exactly when you want the process moving smoothly. Confirm your operational foundation (entity, bank account, compliance manual, custodian relationship) is genuinely in place before you file, not just mostly in place. A registration review that comes back with deficiency comments because the paperwork was rushed costs more time overall than the extra week it would have taken to get the foundation right before filing.

A Registration Sequencing Checklist

In order: form your entity and appoint a registered agent; confirm your current SEC-vs-state registration threshold against NASAA/SEC guidance; decide your principal office location deliberately, factoring in the net-worth and bonding consequences covered in our Location guide; finish your operational foundation (bank account, bookkeeping, policies and procedures manual matching your actual practice); confirm your custodian relationship; then file Form ADV. Once registered, identify every other state where you'll have clients and confirm each one's notice-filing requirement individually rather than assuming uniformity across states.

FREQUENTLY ASKED QUESTIONS

How do I know if I should register with the SEC or with my state?

It's governed by an AUM threshold set by rule, and the specific number is revised periodically — don't rely on a figure from an older article. Confirm the current threshold directly against NASAA and SEC guidance before you plan your registration timeline around it, since the SEC and state paths carry different ongoing obligations.

If I have clients in five states, do I need to register in all five?

Not necessarily as a full registration. Once you're properly registered with the SEC or your home state, most other states require only a notice filing — generally your existing Form ADV plus a fee — rather than a second full review. The exact threshold and requirement for a notice filing vary by state, so confirm each one individually.

Does it matter which state I designate as my principal office?

Yes, beyond just convenience. Under the Investment Advisers Act, your principal office state can determine which state's net-worth and bonding requirements apply to you, even for clients served elsewhere. It's worth deciding deliberately as part of registration planning rather than defaulting to wherever you happen to be sitting when you file — see our Location guide for the specific mechanism.
