SEC Investment Adviser Registration: Requirements, AUM Thresholds, and Compliance Obligations

Registering as an investment adviser with the SEC marks the start of your relationship with the Investment Advisers Act of 1940, not the end of a paperwork process. The moment registration becomes effective, a set of ongoing compliance obligations applies. Understanding the registration thresholds, the filing process, and what comes next will save you from starting behind.

This article covers who must register with the SEC, how the registration process works, and the core compliance requirements -- including Regulation S-P -- that apply to every registered investment adviser.

Who Must Register with the SEC

Not every investment adviser registers with the SEC. The Investment Advisers Act of 1940 created a two-tier registration system based on regulatory assets under management (RAUM): smaller advisers register with state regulators, while larger ones register federally.

The $110 million threshold. Advisers with $110 million or more in RAUM must register with the SEC. This is a hard requirement once the threshold is met.

The transitional window. Advisers with between $100 million and $110 million in RAUM are in a permissive zone: they may register with the SEC if they choose, but are not required to do so. Once AUM reaches $110 million, SEC registration becomes mandatory.

Below $100 million. Advisers with less than $100 million in RAUM generally must register with state securities regulators in the state where they maintain their principal office. State registration requirements vary by state and are administered by the North American Securities Administrators Association (NASAA) member regulators.

The multi-state exception. Advisers who would otherwise register at the state level may register with the SEC if they would be required to register in 15 or more states. This exception exists to relieve advisers with widely distributed clients from navigating 15 separate state registration systems.

Investment company advisers. Advisers to registered investment companies under the Investment Company Act of 1940 must register with the SEC regardless of AUM.

The RAUM calculation is not simply total AUM. It uses a specific definition that includes securities portfolios for which the adviser provides continuous and regular supervisory or management services. You calculate it using the method described in the instructions to Form ADV Part 1A, Item 5. Most advisers should calculate this number carefully before filing, because the threshold determines which regulator has jurisdiction over them.

Exemptions from SEC Registration

Several categories of adviser are exempt from SEC registration even if their advisory activities would otherwise require it. The most significant exemptions are:

Private fund adviser exemption. Advisers who manage only private funds and have less than $150 million in private fund regulatory assets under management in the United States qualify as Exempt Reporting Advisers. They file a truncated Form ADV Part 1 (the ERA filing) but are not registered advisers. Once their private fund AUM reaches $150 million, they must register.

Venture capital fund adviser exemption. Advisers who solely advise qualifying venture capital funds are exempt from registration. This exemption is defined in SEC Release IA-3222 and has specific conditions related to fund structure and leverage.

Intrastate adviser exemption. Advisers whose clients are all residents of the state where the adviser maintains its principal office, who do not give advice about exchange-listed securities, and who are not advisers to investment companies may qualify for the intrastate exemption. This exemption is narrow and many advisers who believe they qualify do not actually meet all of its conditions.

Foreign private adviser exemption. Advisers with no place of business in the United States, fewer than 15 US clients and US investors in private funds advised, and less than $25 million in US AUM may qualify for this exemption.

These exemptions have specific conditions and are subject to change through SEC rulemaking. If you are relying on an exemption, you should confirm it still applies to your current business before each annual review.

How SEC Registration Works

SEC registration is handled entirely through the Investment Adviser Registration Depository (IARD), an electronic filing system operated by FINRA on behalf of the SEC and state regulators.

Creating your IARD account. Before you can file Form ADV, you must establish an IARD account by submitting an entitlement request to FINRA. FINRA assigns a CRD (Central Registration Depository) number to the firm, which becomes your permanent identifier across all SEC and state regulatory filings.

Filing Form ADV Part 1. Part 1 is a structured data form covering your firm's organizational information, ownership structure, business activities, client types, regulatory assets under management, and any disciplinary history. It is the primary source of data the SEC uses to administer the registration system. Once filed, it is publicly accessible through the SEC's Investment Adviser Public Disclosure (IAPD) database at adviserinfo.sec.gov.

Filing Form ADV Part 2A. Part 2 is the advisory brochure -- a plain-English disclosure document that clients receive before entering an advisory relationship. It must be written in narrative form and cover fees, investment strategies, conflicts of interest, disciplinary history, and your firm's privacy policies and information security practices. The Part 2A privacy section is where Regulation S-P intersects with Form ADV: what you disclose in Part 2 about how you protect client information must be accurate and consistent with your actual written Reg S-P program. For a deeper look at how Form ADV and Reg S-P connect, see the SEC Form ADV guide.

Registration fees. Registration fees are paid through the IARD system at the time of filing. The SEC's fee schedule is based on RAUM and is adjusted periodically.

Effectiveness. Your registration becomes effective automatically 45 days after filing a complete Form ADV unless the SEC initiates proceedings to deny registration or grants earlier effectiveness. For straightforward filings with no disciplinary issues, many registrations become effective before the 45-day period lapses. You may not hold yourself out as an SEC-registered investment adviser or accept client assets until registration is effective.

Transitioning from State to SEC Registration

Many advisers begin as state-registered and transition to SEC registration as their AUM grows. The transition has a specific process and timeline.

When the switch is required. If your AUM reaches $110 million, you must file with the SEC. The trigger date is typically identified through your annual Form ADV amendment, which is filed within 90 days of your fiscal year-end. If your AUM has crossed $110 million as of your fiscal year-end, you must file for SEC registration no later than 90 days after that date.

Simultaneous registration. During the transition, you will be registered with both your state regulator and the SEC temporarily. Once your SEC registration becomes effective, you withdraw your state registration.

Withdrawal from state registration. Withdrawal is filed through the IARD system using Form ADV-W. You must file the withdrawal after SEC registration is effective. State withdrawal requirements vary: some states require notification, others have additional procedures.

Falling below the threshold. If your AUM drops below $90 million (the lower end of the transitional window), you must withdraw SEC registration and register with state regulators. The $90 million floor -- not $100 million or $110 million -- is the trigger for mandatory withdrawal, which gives advisers a buffer against switching back and forth due to market fluctuations.

Compliance Obligations That Apply Immediately After Registration

Registration is the starting line, not the finish line. The moment your SEC registration becomes effective, a comprehensive set of ongoing obligations applies.

Rule 206(4)-7: The Compliance Programs Rule. Every SEC-registered investment adviser must adopt written policies and procedures reasonably designed to prevent violations of the Advisers Act and SEC rules. This requires designating a Chief Compliance Officer responsible for administering the compliance program and conducting an annual review of the program's adequacy and effectiveness. The annual review should be documented. Most advisers integrate their full compliance calendar into this annual review. For how Reg S-P fits into the 206(4)-7 review, see the annual compliance review guide.

Regulation S-P: Information Security Program. Reg S-P applies to SEC-registered investment advisers that maintain customer records. It requires a written information security program that covers: an incident response plan for unauthorized access to customer data, a service provider oversight program for vendors with access to client information, technical and administrative safeguards for customer records, and breach notification procedures including the 30-day client notification requirement. Reg S-P is in force for all SEC-registered advisers and is an SEC FY2026 examination priority. For newly registered advisers, the right time to build your Reg S-P program is before you take your first client, not after an examiner asks for it. See the Reg S-P compliance guide for newly registered advisers for a sequenced implementation plan.

Rule 204-2: Books and Records. This rule requires registered advisers to maintain extensive business records for five years, with the first two years in an easily accessible place. Required records include investment advisory agreements, client correspondence, trading records, performance records, financial records, and compliance program documentation. The breadth of the books and records rule is one of the most common areas of examination focus, and gaps in recordkeeping are among the most frequently cited deficiencies. For a full breakdown, see the Rule 204-2 recordkeeping guide.

Form ADV maintenance. Registration is not a one-time filing. You must amend Form ADV annually within 90 days of fiscal year-end. You must also amend promptly when material information changes -- strategy changes, fee changes, new disciplinary events, significant ownership changes. The SEC's position is that promptly means within 30 days for most Part 2 material changes. Letting Form ADV drift out of alignment with your actual business is a routine examination finding.

Client disclosure obligations. You must deliver Form ADV Part 2A to clients before or at the time of entering an advisory agreement, and must offer an updated copy annually or promptly when material changes occur. You must also deliver any applicable Form ADV Part 2B brochure supplement for individual investment adviser representatives who have direct client contact.

Common Registration Mistakes

Several mistakes show up repeatedly in new SEC registrant examinations.

Registering before building the compliance infrastructure. Registration triggers Rule 206(4)-7 immediately. Advisers who register to pursue clients before their compliance program is written start their regulatory relationship with a deficiency already in progress.

Miscalculating RAUM. The RAUM calculation for Form ADV Part 1 follows specific rules. Not all assets count. Not all client relationships count in the same way. Filing with an incorrect RAUM figure -- either high or low -- creates problems that carry forward through every subsequent amendment.

Generic Form ADV Part 2. The Part 2A brochure must describe your firm's actual practices. Using a template with generic language about privacy and information security that does not reflect what your written Reg S-P program actually requires is a documented deficiency pattern. SEC examiners cross-reference Part 2 disclosures against your actual policies.

Missing the amendment deadline. The annual amendment must be filed within 90 days of fiscal year-end. For calendar-year advisers, that is March 31. Missing this deadline is one of the most common and easily avoidable exam findings. Build the deadline into your compliance calendar.

Not preparing a CCO. Rule 206(4)-7 requires a Chief Compliance Officer. For small firms, this is often the founder or principal. The CCO does not need to be a separate hire, but the role must be formally designated and the person must be capable of administering the compliance program.

After Registration: Getting Exam-Ready

The SEC's Division of Examinations conducts routine examinations of registered investment advisers, typically targeting firms that have not been examined recently, newly registered advisers, and firms flagged by risk analytics. New registrants are frequently examined within the first few years of registration.

The best way to prepare is to build your compliance program correctly at registration, not to retrofit it before an exam notification arrives. That means written policies under Rule 206(4)-7, a written Reg S-P program covering all five required elements, organized records under Rule 204-2, and a current, accurate Form ADV.

RegShield generates the four written Reg S-P policy documents that every SEC-registered adviser needs -- the incident response plan, vendor oversight policies, breach notification templates, and recordkeeping procedures -- in approximately 15 minutes. If you are preparing for registration or have recently registered, start the compliance wizard to get exam-ready documentation before your first examination.

Frequently Asked Questions

Do I need a lawyer to register as an investment adviser with the SEC?

The SEC does not require you to use legal counsel to file Form ADV through the IARD system. Many advisers complete their own registration filings. That said, legal counsel familiar with investment adviser regulation can help you calculate RAUM correctly, ensure your Form ADV Part 2 disclosures are accurate and adequate, and structure your compliance program before registration becomes effective. For advisers with complex ownership structures, multiple affiliated entities, or past disciplinary history, legal review before filing is worth the cost.

Can I start accepting clients before my SEC registration is effective?

No. You may not hold yourself out as an SEC-registered investment adviser or provide investment advisory services for compensation until your registration is effective. The 45-day waiting period is a regulatory requirement. You may use the time to build your compliance program, draft client agreements, and complete Form ADV Part 2A. If you need to advise clients before registration is effective, you may need to rely on a registration exemption for the interim period.

What is an Exempt Reporting Adviser?

An Exempt Reporting Adviser is an investment adviser that qualifies for an exemption from SEC registration -- most commonly the private fund adviser exemption or the venture capital fund adviser exemption -- but is still required to file a partial Form ADV Part 1 with the SEC. ERAs are not registered advisers and are not subject to all of the requirements that apply to registered advisers, but they are subject to the anti-fraud provisions of the Advisers Act and some state-level requirements.

Does Regulation S-P apply to state-registered investment advisers?

Regulation S-P as amended by the SEC applies to SEC-registered investment advisers and SEC-registered broker-dealers. State-registered investment advisers are generally not subject to the SEC's Reg S-P, although some states have adopted their own privacy and information security regulations that apply to state registrants. If you are transitioning from state to SEC registration, your Reg S-P obligations begin when your SEC registration becomes effective.

What is the IARD and how do I access it?

The Investment Adviser Registration Depository (IARD) is the electronic filing system through which investment advisers register with the SEC and state regulators and file Form ADV. It is operated by FINRA under an agreement with the SEC and the states. You access it through the FINRA IARD website at iard.com. To establish an account, you submit an entitlement request to FINRA before filing. The IARD system is also how you submit annual amendments, prompt amendments, and ultimately your Form ADV-W withdrawal when you withdraw registration.
