There’s a milestone most California nurse practitioners are working toward: NP 104 certification. It’s the point where standardized-procedure requirements end, the group-setting restriction falls away, and you can open your own independent clinic. If you’re doing the math right now, how many more hours on the post-103 clock, how close you are, this is the guide for you.

If you’re searching for 104 NP California certification, you’re probably close to that point, or planning carefully so you hit it right. This guide covers the eligibility requirements, what NP 104 certification actually authorizes, and the part most guides leave out is how to legally structure the independent practice that certification makes possible.

 

 

What Is 104 NP California Certification?

A California NP 104 is a nurse practitioner certified under Business and Professions Code §§2837.104 who may practice without standardized procedures and outside the group-setting restrictions applicable to a 103 NP. This is the highest level of California NP full practice authority under current law — and the certification that allows you to open and operate your own clinic without a supervising physician, within your national certification’s population focus. 

What AB 890 and SB 1451 Created

Before AB 890, California NPs generally practiced under written standardized procedures; formal protocols developed with physicians that defined what an NP could do within an organized health care system. AB 890, signed September 2020 and effective January 2023, created two new certification categories under BPC sections 2837.100–2837.105: the 103 NP (independent practice within a qualifying group setting) and the 104 NP (independent practice outside those settings). 

SB 1451, effective January 1, 2025, simplified the transition-to-practice requirements and clarified that qualifying hours may be non-consecutive and aggregated across time periods. NP 104 applications first became available January 1, 2026. Both the 103 and 104 pathways are optional. NPs may still choose to practice under standardized procedures. 

103 NP vs. 104 NP California — What’s the Difference?

The 103 NP is a prerequisite for the 104 NP, not an alternative. You cannot skip the 103 stage and apply directly for 104 certification.

The NP 104 Certification Journey at a Glance

The transition-to-practice stage (Step 5) and the post-103 experience requirement (Step 7) are separate requirements that cannot be double-counted. Combined, they represent a minimum of several years between initial NP certification and NP 104 eligibility.

Full Eligibility Requirements for 104 NP Certification in California

Each stage has its own documentation requirements. Missing any one can result in a denial or delay.

Steps 1–4: RN License, NP Education, National Certification, California NP Certification

You need a current, active California RN license. From there: complete an NP education program in your population-focus category, obtain national certification from a Board-recognized organization (such as AANPCB or ANCC where applicable), and apply for your California NP certification through the BRN. Your population focus governs the scope of your NP 104 practice; what your certification covers is what you’re authorized to do.

Step 5: Transition to Practice

Complete 4,600 hours or three FTE years of direct patient care in your population-focus category, in California, within five years before the 103 NP application, after your California NP certification. A supervising physician must complete an attestation. SB 1451 confirmed that hours may be non-consecutive and aggregated across time periods.

Step 6: 103 NP Certification and Qualifying Practice

Submit the 103 NP application through BreEZe. After certification, practice in a qualifying group setting with at least one physician and surgeon in your population-focus category. This is where you build the post-103 experience the 104 application requires.

Step 7: Post-103 Experience Requirement

Practice in good standing as a 103 NP for at least three FTE years or 4,600 hours of direct patient care. This is separate from the transition-to-practice stage, the two cannot be double-counted. “In good standing” means no probation, suspension, or disciplinary action on your license.

If you hold a DNP, qualifying clinical hours from your doctoral program may count toward this requirement under certain conditions (per BRN guidance; see California Code of Regulations, Title 16, § 1482 et seq.). A DNP degree alone, however, does not satisfy the other eligibility conditions. Confirm the current crediting rules with the Board directly before relying on doctoral hours toward the 104 NP application.

Step 8: The NP 104 Application

Submit the NP 104 application through BreEZe with documentation of your California licenses, national certification category, qualifying employment, and post-103 hours. Follow the Board’s current instructions carefully — documentation errors cause significant delays.

What Can a 104 NP in California Actually Do?

Authorized Clinical Functions

Under AB 890, 103 and 104 NPs may perform the following functions without standardized procedures, within their population focus and consistent with their education and training: 

• Conduct an advanced patient assessment 
• Order, perform, and interpret diagnostic procedures (including radiologic procedures) 
• Formulate a differential diagnosis and develop a treatment plan 
• Prescribe and furnish drugs and devices, subject to applicable furnishing and prescribing laws 
• Order, perform, and evaluate therapeutic interventions 
• Refer patients to and consult with appropriate healthcare providers 

For an NP 104, these functions may be performed outside the group settings required for 103 NP practice in your own independent clinic. Confirm current authorized scope with the Board before relying on this list for practice planning. 

What NP 104 Doesn’t Cover

NP 104 does not eliminate all constraints. You must still practice within your population focus, comply with furnishing and prescribing laws, and maintain a written consultation and referral plan for complex cases per BPC § 2837.104(c)(2). Operating through an improperly formed business entity can also create compliance problems regardless of certification status.

Can a California NP 104 Open an Independent Practice Without a Physician?

Yes. NP 104 certification removes both the standardized-procedures requirement and the group-setting restriction. You can open and operate an independent clinic without a supervising physician which is the primary reason most NPs pursue this certification.

But clinical authority and business structure are two different things. The certification gives you the right to practice independently. A properly formed professional corporation gives you the legal vehicle to do it safely.

Staffing, Billing, and Leasing

Running an independent practice means employing staff, credentialing with payers, and signing leases. Most payers require the billing entity to match your license type; the wrong entity type can be rejected during credentialing, delaying revenue from day one. Commercial leases should also be signed in the entity’s name after formation, not personally, to avoid direct liability exposure.

Planning for Growth and Multiple Locations

If your model includes more than one location, the same professional corporation typically operates all of them. Each site may require its own local business license and payer credentialing. Thinking through the structure at formation is far less expensive than restructuring a live practice later.

How to Structure Your NP 104 California Practice — The Business Side

NP 104 certification opens the door to clinical independence. Business formation is what lets you walk through it legally. Reaching this stage means you’ve earned the right to practice on your own terms — but the practice itself, the entity that employs staff, bills payers, and signs leases, needs a legal structure that holds up under California’s specific requirements for licensed healthcare professionals. This is the section most clinical guides skip. It’s also where Incorporation Attorney’s work begins with helping licensed healthcare professionals form the right entity from the start rather than unwind the wrong one later.

Why a Standard LLC Doesn’t Work for Most California NPs

California generally does not permit licensed healthcare professionals to deliver professional services through a standard LLC. The LLC structure isn’t authorized to render services requiring a professional license under California law. An NP who forms an LLC may be operating an entity that isn’t legally authorized to provide the services the practice delivers. 

Online incorporation services don’t ask what kind of professional you are as they file the paperwork and send a confirmation. The problem stays invisible until it surfaces in a payer credentialing audit, a licensing board review, or a malpractice dispute. For a full overview, see our page on California nurse business entity options. 

The Professional Corporation Requirement

In most cases, California NPs who open an independent practice will need to form a nurse practitioner professional corporation — a specific entity type authorized under the Moscone-Knox Professional Corporation Act (Cal. Corp. Code §§13400–13410). The requirement depends on your specific practice model and the professional services involved, which is why it matters that the formation is analyzed by someone who understands both your license type and the applicable statutes. 

See our page on nurse practitioner professional corporation requirements in California for the baseline requirements. 

LLC vs. Professional Corporation vs. Sole Proprietorship

Ownership and Control Rules

California’s Corporate Practice of Medicine (CPOM) doctrine restricts non-licensed individuals from owning or controlling entities that provide professional medical services (Cal. Bus. & Prof. Code §§2400 et seq.). The ownership structure of an NP professional corporation must be analyzed against both the Moscone-Knox Professional Corporation Act (Cal. Corp. Code §§13400–13410) and CPOM before you file. 

Getting this wrong isn’t a formality problem. It can affect the entity’s validity, create exposure in a malpractice claim, and raise questions with the licensing board. This is not a DIY analysis, the consequences of an incorrect ownership structure can follow the practice for years. 

Tax Considerations for Your NP Professional Corporation

Professional corporations in California are subject to the state’s 1.5% franchise tax on net income (with a minimum annual franchise tax). Unlike a sole proprietorship where all practice income flows directly to your personal return, a professional corporation allows you to structure compensation between salary and distributions which can have meaningful tax implications depending on your income level.

Professional corporations may elect S-Corporation tax treatment at the federal level, which affects how profits are distributed and taxed. However, California does not fully conform to the federal S-Corp treatment, the 1.5% tax still applies. These decisions are made at formation and are worth working through with both a formation attorney and a CPA who understands healthcare professional entities before you file.

Ongoing Compliance for California NP Professional Corporations

Forming the entity is the beginning, not the end. A California professional corporation has annual compliance obligations that must be maintained to keep the entity in good standing:

• File a Statement of Information with the Secretary of State annually (required within 90 days of incorporation, then every year per Cal. Corp. Code §1502) 
• Hold and document annual corporate meetings and maintain corporate minutes 
• Renew the entity’s business license and any local permits 
• Maintain the NP’s California license and national certification in good standing 
• Ensure any employed licensed professionals also maintain their licenses 
• Comply with California employment law for any staff — proper classification, payroll, workers’ compensation

Failing to maintain these formalities can expose the corporate veil to challenge, meaning personal assets may no longer be protected in a dispute. The same care that goes into the clinical side of the practice needs to go into the compliance calendar.

Naming, DBAs, and Other Business Models

California has specific naming rules for NP professional corporations, non-compliant names won’t be approved and cause refiling delays. If you want a public-facing name different from the legal entity name, that’s handled through a fictitious business name. See our page on California nurse practitioner business names before you file. 

If your model involves a registry, group practice, or multi-facility contracting rather than a solo clinic, the entity requirements change. Our guide on starting a nursing registry business in California covers those specifics. 

Common Mistakes New 104 NP California Practice Owners Make

Mistake 1 — Forming an LLC Instead of a Professional Corporation

The most common and most damaging error. A standard LLC isn’t authorized to provide licensed healthcare services in California, but online filing services process the paperwork without asking what kind of professional you are. The problem stays invisible until it surfaces in a payer credentialing rejection, a licensing board inquiry, or a malpractice dispute where the entity structure is challenged.

Mistake 2 — Filing for NP 104 Before Meeting All Eligibility Requirements

The transition-to-practice stage and the post-103 experience requirement are separate. Many applicants conflate them and submit the 104 application before the post-103 hours are complete. Review your timeline against both requirements before you file.

Mistake 3 — Signing Leases and Contracts in Your Personal Name

Signing a commercial lease before the professional corporation is formed means personal liability for those obligations. Form the entity first, then execute leases and vendor agreements in the entity’s name.

Mistake 4 — Ignoring Payer Credentialing at Formation

Payer credentialing applies to your entity, not just to you individually. An entity with the wrong type, wrong name, or mismatched ownership structure can be rejected during credentialing with Medicare, Medi-Cal, or commercial insurers which can cause delaying revenue from day one.

Mistake 5 — Skipping Annual Compliance After Formation

Forming the corporation correctly is step one. Missing annual filings, failing to maintain corporate minutes, or letting licenses lapse can erode the entity’s good standing and expose the corporate veil to challenge. Compliance doesn’t end at formation.

Why the Right Corporate Formation Protects Your NP 104 License

An Orange County client came to us after using an online incorporation service. They had formed a standard LLC, filed a DBA, and were ready to open a healthcare practice. What they hadn’t verified was whether that entity type was authorized for a licensed NP in California. It wasn’t. 

When you form a professional corporation correctly — through a process that understands your license type and California’s healthcare professional corporation requirements — the legal protections are built in from day one. The corporate formalities. The ownership structure. The governance documents that answer the questions a licensing board or opposing counsel would ask.

Frequently Asked Questions — 104 NP California

What is the difference between a 103 NP and a 104 NP in California?

A 103 NP may practice without standardized procedures only in a qualifying group setting with at least one physician. A 104 NP may practice outside those group-setting restrictions within their population focus. The 103 NP is a prerequisite for the 10, not an alternative.

Can an NP 104 own an independent practice in California?

Yes. NP 104 certification removes both the standardized-procedures requirement and the group-setting restriction that applies to 103 NPs. You can open and operate an independent clinic without a supervising physician. You’ll still need to operate through a properly formed nurse practitioner professional corporation in most cases, comply with furnishing laws, and maintain a consultation and referral plan for complex cases.

Does NP 104 still require physician collaboration?

No — NP 104 certification removes the standardized-procedures agreement and the group-setting requirement that previously mandated physician involvement in the practice structure. You are not required to have a collaborating or supervising physician. You are still required to refer and consult on cases outside your clinical competency or population focus, and to maintain a written plan for those situations under BPC § 2837.104(c)(2).

How long does it take to get NP 104 certification in California?

The full pathway from RN to NP 104 typically takes many years. After obtaining your California NP certification, you must complete 4,600 hours or three FTE years of transition-to-practice experience before applying for 103 NP status. After receiving 103 NP certification, you must practice in good standing for another 4,600 hours or three FTE years before the 104 application. Because these stages are sequential and cannot be double-counted, the minimum time from initial NP certification to 104 eligibility is typically over three years — and often longer depending on part-time practice patterns.

Should I form an LLC or a Professional Corporation as an NP 104?

In most cases, a professional corporation is the required structure, not an LLC. California generally does not permit licensed healthcare professionals to provide professional services through a standard LLC. An NP 104 who forms an LLC risks operating an entity that isn’t legally authorized to deliver the services the practice provides, which can surface during payer credentialing, a licensing board audit, or a malpractice dispute. A nurse practitioner professional corporation, properly formed and matched to your license type, is the structure that works.

What did SB 1451 change for NP 104 applicants?

SB 1451, effective January 1, 2025, simplified the transition-to-practice requirements: qualifying hours may now be non-consecutive and aggregated across time periods. It also updated patient disclosure requirements and confirmed that NP 104s are eligible for full medical staff membership at healthcare facilities.

Do I need a professional corporation as an NP 104 in California?

In most cases, yes. California requires licensed healthcare professionals to operate through a professional corporation rather than a standard LLC when providing professional services. The exact requirements depend on your practice model, which is why entity formation should be handled by someone who understands your license type and California’s healthcare professional corporation rules.

Building Your 104 NP California Practice — The Clinical and the Business

Reaching NP 104 certification in California takes years of sustained clinical work. The business decisions that follow deserve the same care.

NP 104 certification gives you the authority to practice without standardized procedures and outside the group-setting restrictions. But the practice itself needs a legal foundation that matches. The wrong entity — or the right entity formed incorrectly — creates compliance exposure that can surface in a payer credentialing audit, a licensing board review, or a malpractice dispute at the worst possible moment.
