How to Start a Therapy Private Practice in California: Step-by-Step for LMFTs, LCSWs, and LPCCs

Before you start: are you allowed to practice independently?

California only lets licensed clinicians run their own practice. If you’re an AMFT, ASW, or APCC, the BBS is clear: you can work as a W-2 employee or volunteer in someone else’s private practice after your registration is issued, but opening your own office is unlicensed practice, and associates can’t take payment from clients directly. See the BBS associate FAQ and Business and Professions Code 4980.43.3.

If you’re still an associate, plan ahead instead: map your hours, your exam date, and a realistic launch timeline on the associate stage page.

Step 1: Decide what kind of practice you’re building

Most of the setup work flows from three choices you make up front:

• Side practice or full-time? A few evening clients while keeping your W-2 job needs a much smaller setup than a full caseload. If that’s you, start with the side practice page.
• How clients will pay. Cash-pay, an insurance platform like Headway or Alma, direct contracts with insurance companies, Medi-Cal, or a mix. This decision drives your paperwork, your cash flow, and your timeline. Compare them in Headway vs. Alma vs. direct insurance.
• Telehealth, in-person, or hybrid. In-person means an office lease or sublease. Telehealth-only still needs a professional address so your home address doesn’t end up on your website, insurance directories, and Google.

Step 2: Choose a business structure

Many therapists assume they should form an LLC. In California that usually doesn’t work for the clinical practice itself: Corporations Code 17701.04(e) says the LLC act doesn’t permit an LLC to render professional services. The common options are:

• Sole proprietorship under your own name. Simplest to start; no separate filing with the Secretary of State.
• Professional corporation (for example, a marriage and family therapy corporation). Filed with the California Secretary of State, with ownership rules in Corporations Code 13401.5.

I walk through the tradeoffs in Professional corporation vs. LLC for therapists. This is a legal and tax decision, so confirm yours with an attorney and a CPA.

If you practice under any name other than your own legal name, check the BBS and county rules for business names before you print anything.

Step 3: Get your identifiers

1. NPI (National Provider Identifier). Apply free through CMS’s NPPES system. Individual clinicians get a Type 1 NPI; a corporation gets its own Type 2 NPI.
2. EIN. A sole proprietor without employees can often use their SSN, but many therapists get a free EIN from the IRS so their SSN isn’t on every W-9 and claim form. A corporation needs one.
3. Business bank account. Keep practice money separate from day one. It makes taxes, bookkeeping, and any audit much easier.
4. Local business license. Many California cities and counties require one, including for home-based businesses. Check with your city.

Step 4: Protect yourself

• Professional liability (malpractice) insurance in your own name for your private practice. Your agency’s policy usually does not cover your side clients. If you plan to enroll in Medi-Cal, DHCS lists minimum coverage amounts on its enrollment pages, so check those before you buy.
• HIPAA basics. A HIPAA-capable EHR with a signed Business Associate Agreement, a secure phone and fax option, encrypted email for anything containing client information, a written risk assessment, and written policies. The HHS HIPAA for professionals pages are the official starting point.
• Informed consent and disclosures. Your intake packet should cover fees, cancellation, telehealth, confidentiality limits, and the disclosures the BBS requires. Confirm current BBS requirements.

Step 5: Set up how you’ll get paid

If you’ll take insurance, the clock matters most here. Credentialing and contracting with an insurance company or Medi-Cal can take weeks to months, so start these early, ideally while you’re still employed:

• Build your CAQH ProView profile first. Most commercial payers pull from it.
• Read how insurance credentialing works and apply to the plans your future clients actually carry.
• If you want to serve Medi-Cal members, read PAVE enrollment and how to bill Medi-Cal.

Nothing here guarantees a payer will accept you, and some panels are closed in some areas. Always confirm network status and effective dates in writing before you see members under a contract.

Step 6: Plan for taxes from your first paycheck

Nobody withholds tax from private practice income. As a self-employed therapist you will generally owe federal income tax plus self-employment tax, and California income tax, and you’ll usually pay them quarterly. The IRS explains this on its estimated taxes page. A simple habit: move a set percentage of every deposit into a separate tax savings account, and let a CPA set that percentage.

Step 7: Get found by the right clients

• A simple, fast website with your license type and number (California’s advertising rules require this; see 16 CCR 1811), what you treat, who you see, how to book, and how you take payment.
• A Google Business Profile set up correctly, especially if you’re telehealth-only or work from home.
• One or two directory profiles where your clients actually look.

Details are in Therapist website SEO and Google Business Profile. No one can promise you a ranking, but the basics done well go a long way.

Common mistakes I see

• Forming a regular LLC for the practice, then finding out later it doesn’t fit California’s professional services rules.
• Using your home address on your website, NPI record, or Google profile.
• Seeing insurance clients before your contract’s effective date is confirmed in writing.
• Spending first-quarter income without setting aside estimated taxes.
• Treating setup as one weekend’s work. It’s a project, and it’s easier with a checklist. Grab the free California Private Practice Launch Checklist.
