Opening a private practice in California: what the rules actually require, in order.

Sixteen items between a license and a first private client, each with the rule it comes from and the page here that goes deeper. Tick them as you go; the ticks stay in this browser and nowhere else. Nothing here is legal advice, and the sources are the Board’s statutes and the federal rules themselves.

The list

Sixteen things, each with the rule that makes it one.

The Board’s items apply to every license it issues; the section numbers cited are the LMFT ones with the LCSW, LPCC and LEP parallels named in the rule text. Federal items apply to every practice. The city item is the one this page cannot source for you.

Choose the entity: sole proprietor or professional corporation
An LLC is closed to California-licensed MFTs, LCSWs, LPCCs and psychologists (Corp. Code §17701.04(e)). The choice is sole proprietorship or a professional corporation, which may elect S-corp treatment; the corporation costs $800 a year from year two whatever it earns.
Corp. Code §17701.04The corporation costs $800 before you see a client
If the practice trades under a name that is not yours, disclose the owner
A licensee who owns a business under a fictitious business name may not use a name that is false, misleading or deceptive, and must tell the client, before treatment starts, the name and license designation of the owner or owners (B&P §4980.46 LMFT; §4992.10 LCSW; §4999.72 LPCC; §4989.47 LEP). The county filing itself is under B&P §17910.
B&P §4980.46The BBS advertising rule: a checklist
Get an Employer Identification Number
Free, online, from the IRS in one sitting. A sole proprietor may use a Social Security number instead, but an EIN keeps it off superbills and W-9s; a corporation must have one.

Get a National Provider Identifier
Free, from CMS’s NPPES. Every insurance claim, every superbill a client submits, and every credentialing application asks for it; it is the number that follows you between employers and practices.

Display the license where you practice in person
A licensee shall display their license in a conspicuous place in the primary place of practice when rendering services in person (B&P §4980.31; §4996.7; §4999.70; §4989.48).
BBS display and notice sheetCalifornia LMFT license renewal checklist
Give every client the Notice to Clients, and document it
Written in at least 12-point type, before services start or as soon as practicable: the Board receives complaints, its web address and phone. From 1 July 2025 it must also carry your full name as filed with the Board, license number, license type and expiration date, and delivery must be documented (B&P §4980.32; §4996.75; §4999.71; §4989.17).
B&P §4980.32The Notice to Clients generator: the statute’s words, your details
Disclose the fee, or how it is computed, before treatment
Failing to do so is unprofessional conduct for every license the Board issues (B&P §4982(n); §4992.3(o); §4999.90(n); §4989.54(o)). Put it in the consent paperwork; a later change is a changed basis.
B&P §4982The fee-increase calculator
Give self-pay clients a good faith estimate
Under the No Surprises Act rule at 45 CFR 149.610, uninsured and self-pay clients get a written estimate of expected charges, and a new one when the charges change.
45 CFR 149.610The good faith estimate builder: every required element, printed
Post and hand out a Notice of Privacy Practices
A HIPAA covered entity provides its notice at first service, posts it where clients can see it, and on its website if it has one (45 CFR 164.520). Whether you are a covered entity turns on electronic transactions with payers; most practices that bill insurance are.

Check every advertisement against the Board’s rule
License type and number in every ad, the trainee and associate disclosures, and the April 2026 changes. The site’s checklist goes item by item.

If you will see anyone by video, meet the telehealth requirements
Consent to telehealth obtained and documented; the risks and limits explained; your license number and type provided; the client’s location and emergency resources established each session. The Board’s own guidance sheet is the source.

Decide on liability insurance
No law requires it of a solo practice; every payer contract and most office leases do, and the site’s page shows the published premiums and what a Board defense costs.

Set up how records are kept, for seven years
Records are retained at least seven years from the date therapy ends; for a minor, seven years after the client turns 18. Written or electronic (B&P §4980.49; §4993; §4999.75; §4989.51). Choose the record system before the first note, not after.
B&P §4980.49The records-request deadline and retention-date calculator
Tell the Board your new address within 30 days
Every licensee and professional corporation keeps a current mailing address with the Board and reports any change within 30 days, old and new (16 CCR §1804); email address changes within 30 days too (B&P §4990.07).

Ask your city about business tax registration
Cities register businesses and charge business tax on their own terms; this page does not state any city’s rule. The city’s finance or treasurer’s office is the source, and the answer belongs in your file.

Why this order

Entity first, numbers second, paper third, calendar last.

01Entity before anything with your name on it.

The EIN, the NPI, the bank account and the payer applications all ask what kind of business you are. Deciding after they are filed means filing them twice.

02The two federal numbers before the first claim or superbill.

Both are free and same-day; both are on every form that follows.

03The paperwork the client signs or sees before session one.

The Notice to Clients, the fee disclosure, the good faith estimate and the privacy notice are all “before services” rules. One intake packet, checked once against each rule, covers them.

04The calendar last, because it never ends.

Estimated taxes, the 30-day address rule, the seven-year records clock and the renewal cycle are the recurring part; the compliance calendar page turns them into dates.

Then what

The rules are met. These pages price the practice they now govern.

What the first year costs

Start from the take-home you need and work back to the fee.

The insurance decision

The insurance navigator

Whether to panel, with whom, and what each network actually pays.

The week itself

My practice desk

The weekly operating desk, and the compliance calendar that goes with it.

The other end

Closing a practice, with the professional will

The duties that outlive a practice, and the four items to write while nothing is wrong.

Where every figure came from

Sources.

Section numbers are given for the LMFT Act; the parallel LCSW, LPCC and LEP sections are named in each item. City business-tax rules are not stated here. Nothing on this page is legal advice.

Source links

This page links to official or statutory references. Check the relevant source and its date; links alone do not document a review.

You should not have to work this part out on your own.

Once a month: free tools and apps worth having, better ways to run the admin side of a practice, what other California therapists are actually doing, and anything new here that might save you an afternoon.

About monthly. One click to leave. Never sold, never shared. The consent box is separate and unticked because California requires it — and because it should be.
