How to Start a Personal Training Business in California

October 29, 2026

You can start a personal training business in California without a state license, exam, or registration. The harder work is everything around the training: choosing a legal structure, getting insurance that gyms will accept, classifying any other trainers you bring on under California's AB5 rules, and registering with your city. This guide covers those steps in the order you should handle them.

The Law vs. What Gyms and Clients Expect

Do you need a license to be a personal trainer in California?

No. California has no state license for personal trainers. The Secretary of State issues no business licenses or permits, and the CDTFA seller's permit is not a business license either. Your real requirements come from three sources: your business entity registration, your city or county, and any licensed activity you add to your services.

The law does not require certification, but gyms, insurers, and clients usually expect it. In practice, you should plan on:

• A certification from a nationally recognized provider. Most gyms look for one accredited by the National Commission for Certifying Agencies (NCCA), such as NASM, ACE, ACSM, or NSCA.
• A current CPR and AED certification.
• A certificate of insurance that shows liability coverage.

Certification costs, exam fees, and renewal rules vary by provider and change over time. Check each provider's current requirements directly before you enroll.

Watch your scope. Personal training is not a licensed health profession in California, but nearby services are regulated. Physical therapy, rehabilitation, and medical nutrition therapy are governed by state licensing boards under the Department of Consumer Affairs. Claims to diagnose or treat injuries can cross those lines, so confirm your scope with the Department of Consumer Affairs before you offer anything beyond exercise programming and general wellness coaching.

Materials and Preparation Checklist

Gather these before you file anything:

• A business name checked against the Secretary of State's business search.
• A current certification from an NCCA-accredited provider and a current CPR and AED card.
• Quotes or applications for general liability and professional liability insurance.
• A federal Employer Identification Number (EIN) from the IRS and a separate business bank account.
• A written service agreement, a liability waiver, and a cancellation policy, reviewed by an attorney.
• A list of the local offices to contact: your city business tax or licensing office, your county clerk-recorder, and your city planning department if you will train from home.

Step 1: Choose and Register Your Business Structure

Your structure determines your state paperwork. Most solo trainers start as sole proprietors or LLCs.

Option A: Sole proprietorship

If you operate under your own legal name, you file no state entity paperwork. The downside is that a sole proprietorship does not separate your personal assets from business debts or claims.

If you use any name other than your legal name, such as Peak Form Training, you must file a Fictitious Business Name Statement. Key rules:

• Where: the county clerk-recorder in the county of your principal place of business.
• Timing: within 40 days of starting the business.
• Publication: published in a newspaper once a week for four weeks. The publication fee is separate from the filing fee.
• Fee: the statutory fee is $10, plus $2 per additional name or owner (Business and Professions Code 17929). Counties charge more, so check your county's fee schedule.
• Expiration: the statement expires after five years.

Details and forms are on the Secretary of State's fictitious business name page.

Option B: Limited liability company (LLC)

An LLC is the most common choice for a trainer who wants liability protection. California does not allow a domestic series LLC. Personal training is not a licensed profession, so an LLC can be used for this business. Follow these steps:

1. Check and reserve the name. The name must include 'limited liability company,' 'L.L.C.,' or 'LLC.' 'Limited' may be shortened to 'Ltd.' and 'company' to 'Co.' The name cannot contain 'bank,' 'trust,' 'trustee,' 'incorporated,' 'inc.,' 'corporation,' or 'corp.' A name reservation costs $10 and lasts 60 days. It cannot be renewed for consecutive periods.
2. File Articles of Organization (Form LLC-1). The filing fee is $70 and is submitted through bizFile Online. Online filings are normally processed within about 5 business days or less. Paper filings take 10 or more business days. Expedited options from the Secretary of State are $350 for 24-hour service, $750 for same-day service if received by 9:30 a.m., and $500 for 4-hour service (drop-off only, precleared).
3. Appoint a registered agent. The agent must be an individual who lives in California or a corporation holding a Corporations Code 1505 certificate. The LLC must also keep an office address in California.
4. Write an operating agreement. You do not file it with the state, but it sets the rules for ownership and management, and banks and attorneys will ask for it.
5. File the Statement of Information (Form LLC-12). The fee is $20. It is due within 90 days of filing the articles, then every two years during the six-month window ending on the last day of the anniversary month. Missing it can trigger a $250 penalty.
6. Plan for the franchise tax. Every LLC owes the $800 minimum annual franchise tax from its first year if it was organized or registered in 2024 through 2026. If your first taxable year begins in 2027, 2028, or 2029, the first-year amount may be $400 under RTC 17941(g)(2), so confirm it with the Franchise Tax Board. The LLC fee applies once California-source total income reaches $250,000, $500,000, $1,000,000, or $5,000,000, at $900, $2,500, $6,000, or $11,790 respectively.

Option C: Corporation

Corporations are rarely the first choice for a solo trainer. Articles of Incorporation cost $100, and the Statement of Information (Form SI-550) costs $25 every year. Tax treatment differs from an LLC's, and a newly incorporated or qualified corporation or S corporation owes no $800 minimum tax in its first taxable year. Talk to a CPA before you choose.

Step 2: Get Insurance Before You Train Anyone

Insurance is a practical requirement, not a formality. Gyms usually ask for a certificate of insurance before they let you train on their floor, and clients may ask for proof too. Ask about two types of coverage:

• General liability covers third-party bodily injury and property damage, such as a client who falls and is hurt during a session.
• Professional liability, sometimes called errors and omissions, covers claims that your instruction or advice caused harm.

Tell the insurer exactly where you train: gym floors, client homes, parks, or outdoor sites. Coverage often differs by location. Ask whether the gym can be listed as an additional insured on the certificate, and get the gym's insurance requirements in writing. Compare quotes from several carriers or a broker, since premiums vary widely by provider and coverage. This guide does not list premium figures.

Workers' compensation is required as soon as you have an employee. An uninsured employer commits a misdemeanor punishable by up to one year in jail, a fine of up to double the premium that would have been paid (but not less than $10,000), or both (Labor Code 3700.5). The state can also issue a stop order with a $1,500 penalty per employee (Labor Code 3722). If you hire your first trainer, bind a workers' compensation policy before that person starts work.

Step 3: Hiring Other Trainers Under AB5

Many owners want to add trainers as independent contractors to avoid payroll. California's AB5 law makes that harder than most people expect.

The starting point is the ABC test in Labor Code 2775. A worker is presumed to be an employee unless the business proves all three conditions: (A) the worker is free from its control and direction, (B) the work is outside the usual course of the business's work, and (C) the worker is customarily engaged in an independently established trade.

Prong B is where most personal training businesses fail. If your business sells training and the trainer delivers training to your clients, the trainer is performing your core service. A trainer who works under your brand, uses your schedule and pricing, and takes your clients is usually an employee.

Two exemptions come up often:

• Do not rely on the professional services exemptions in Labor Code 2778. Personal trainers are not on that individual-professional list.
• The business-to-business exemption in Labor Code 2776 may fit a trainer who runs a real independent business with their own clients, marketing, pricing, and location. It requires a written contract with payment terms and a due date, a separate business location, any business license or tax registration the locality requires, and other statutory factors. A California employment attorney should review the arrangement before you rely on it.

The structure must match the facts. A trainer who rents space at a gym, sets their own rates, and trains their own clients is a different relationship from a trainer working under your company's name. Paperwork cannot fix a relationship that looks like employment in practice.

If you do hire employees, register with the Employment Development Department (EDD) and pay at least the state minimum wage. The state minimum is $16.90 in 2026 and $17.40 starting January 1, 2027, according to a secondary source, so verify both figures with the state labor agency. Some cities set higher minimums.

Step 4: Sales Tax and Product Sales

Product sales and training services can be treated differently for sales tax. If you sell taxable goods such as supplements, apparel, or equipment, you need a seller's permit from the California Department of Tax and Fee Administration (CDTFA). The permit is free. The statewide base sales tax rate is 7.25%, and with district taxes, city rates run from 7.25% to 11.75%. A resale certificate has no required form.

Whether and how training services are taxed depends on the facts, so confirm the treatment with the CDTFA before you invoice clients. Do not assume that a service is always exempt or always taxable.

If you offer home gym installation, note that the Contractors State License Board license threshold is $1,000. Assembling equipment you sell is different from building or installing improvements to a property, so check with the board before you take on installation work.

Step 5: Local Permits and Registrations

California has no general statewide business license, but local rules fill the gap. Of the 483 cities, 445 report revenue from a local business tax or registration certificate. There is no common formula, so the answer depends on your city. Counties license only regulated activities.

• City business tax or registration: check with your city's business tax or revenue office, and ask whether the rule applies to a service business with no physical storefront.
• Home-based training: zoning rules may limit client visits, parking, signage, and equipment at a residence. Check with the city planning department before you train clients at home.
• Public parks: outdoor training in parks usually requires a permit from the city or county parks department. Check with the agency before you advertise park sessions.

Step 6: Set Realistic Expectations and Write Claims Carefully

Your marketing is part of your legal risk. Describe outcomes in hedged terms and avoid language that promises results or treats a condition. Clients may notice better strength, mobility, or consistency over several weeks, and results depend on starting fitness, effort, sleep, and nutrition.

• Use phrasing such as 'designed to support,' 'many clients report,' or 'may help improve.'
• Avoid 'guaranteed results,' 'burn fat in 10 days,' and any claim that exercise cures or reverses a disease.
• Do not cite statistics you cannot document.
• If you sell supplements, have the claims on the label and in your marketing reviewed, since those products face stricter rules than training services.

Common Mistakes to Avoid

• Assuming a 'professional exemption' covers you. Personal trainers are not on the Labor Code 2778 list.
• Calling trainers independent contractors without a real business relationship. If prong B fails, the label does not matter.
• Treating the seller's permit as a business license. You still need your city registration.
• Using a restricted word in an LLC name, such as 'bank' or 'trust.'
• Missing the LLC-12 deadline. Calendar it when you file the articles.
• Hiring your first employee before workers' compensation is in place.
• Skipping written contracts and waivers. A verbal agreement is hard to defend.
• Overpromising results in ads, social posts, or testimonials.
• Offering services that belong to licensed professions without checking the scope first.

Tips for a Smoother Launch

• File online through bizFile Online when speed is not critical, and pay for expedited service only if you need the filing quickly.
• Get free one-on-one advising from a California Small Business Development Center (SBDC) advisor at californiasbdc.org.
• Get your insurance certificate before you sign a gym agreement or a first client contract.
• Document each trainer's independence in the written contract, including their rates, schedule control, and client relationships.
• Start with one training location and one service model. You can expand after your paperwork and insurance are settled.

Next Steps

Start with the Secretary of State's Business Programs Division page to confirm your entity steps. Then call your city's business tax office and your county clerk-recorder. Finally, have an insurance broker and a California employment attorney review your structure before you hire anyone.
