To become an independent contractor in California, you need to confirm you qualify under the state’s ABC test, choose a business structure, register with the Secretary of State (if you form an LLC or corporation), obtain the local licenses and tax IDs your work requires, and set up quarterly tax payments to both the IRS and the Franchise Tax Board. The steps below walk through each piece in the order most people need to handle them.
Confirm You Qualify Under the ABC Test
Before you register anything, make sure the law will actually treat you as an independent contractor. California presumes every worker is an employee. The company hiring you carries the burden of proving all three parts of the ABC test, codified in Labor Code Section 2775, before it can classify you as a contractor.1Labor Agency home page. ABC Test
- Prong A — Freedom from control. You must be free from the hiring company’s control over how you do the work, both on paper and in practice. If the company dictates your hours, tools, or methods, this prong fails.
- Prong B — Outside the company’s usual business. The work must fall outside what the company normally does for its customers. A tech company hiring a freelance software developer for its core product has a much harder time here than one hiring an electrician to rewire its office.
- Prong C — Independent business or trade. You must operate your own established business in the same field as the work. Multiple clients, your own equipment, and a business registration all help demonstrate this.
Failing any single prong means the law treats you as an employee.1Labor Agency home page. ABC Test Companies that worry about misclassification exposure often ask contractors to demonstrate they meet the test before signing, so having a registered business, multiple clients, and your own tools puts you in a stronger position.
One boundary worth flagging: certain licensed professions don’t get evaluated under the ABC test at all. Licensed insurance agents, physicians, surgeons, dentists, psychologists, veterinarians, attorneys, architects, engineers, private investigators, and accountants are instead classified under the older Borello multi-factor test, along with certain direct salespeople, registered securities broker-dealers, and commercial fishermen.2Franchise Tax Board. Worker Classification and AB 5 FAQs Borello weighs the whole working relationship and is generally easier to satisfy, but you still have to show genuine independence.
Choose a Business Structure
Most independent contractors in California pick one of three structures.
A sole proprietorship is the simplest. There’s no state formation filing, no separate tax return for the business, and minimal paperwork. The tradeoff is that your personal assets are fully exposed if someone sues your business or you take on debt. Many contractors start here and upgrade later.
A limited liability company (LLC) creates a legal wall between your personal finances and your business debts. It’s the most popular choice for contractors who want liability protection without corporate formality. The catch is California’s $800 annual franchise tax, owed even in years the business earns nothing. California previously offered a first-year exemption, but that expired for tax years beginning on or after January 1, 2024, so new LLCs formed in 2026 owe the $800 from the first year.3Franchise Tax Board. Limited Liability Company If your expected income is modest, a sole proprietorship may make more sense until the liability protection is worth the annual cost.
A corporation offers the strongest liability protection and a more formal structure, but comes with more paperwork, separate tax filings, and stricter recordkeeping. Most solo contractors don’t need it.
Register With the Secretary of State
If you go with an LLC or corporation, you file formation documents through the California Secretary of State’s bizfile online portal.4California Secretary of State. bizfile For an LLC, that’s Articles of Organization (Form LLC-1): business name, management structure, and agent for service of process. The filing fee is $70. Corporations file Articles of Incorporation, which include details like the number of shares the entity can issue, at a cost of $100.5California Secretary of State. Business Entities Fee Schedule
Your agent for service of process is the person or company authorized to receive legal papers if the business gets sued. It can be you personally or a third-party registered agent service. The agent’s name and street address become public record on the Secretary of State’s website.6California Secretary of State. Frequently Asked Questions If you work from home and don’t want your home address in a searchable public database, a registered agent service solves that. Your business entity cannot serve as its own agent.
Online filings typically process within five to ten business days. Once approved, you receive a certified copy of your documents electronically, which is your official proof that the business exists.
Statement of Information
Within 90 days of forming your LLC or corporation, file a Statement of Information with the Secretary of State. LLCs file Form LLC-12 ($20); corporations file Form SI-550 ($25). This gives the state current contact information for the managers or officers. Miss the deadline and you’re looking at a $250 penalty and eventual suspension of the entity.7California Department of Industrial Relations. Instructions for Completing the Statement of Information
File a Fictitious Business Name if You Need One
If you operate under any name other than your own legal surname, or the registered name of your LLC or corporation, file a Fictitious Business Name statement with the county clerk where your business is based. The filing has to happen within the first 40 days of operating, and within 30 days after that filing you must publish the name in a local newspaper of general circulation, once a week, for four consecutive weeks.8California Office of the Small Business Advocate. Setting Up Your Business in California
County filing fees and newspaper publication costs vary. Combined, they can range from under $100 to several hundred dollars depending on location and newspaper rates. Sole proprietors doing business under their own last name can skip this entirely.
Handle Local Licenses and Any Professional Permits
Most California cities and counties require anyone conducting business within their jurisdiction to hold a local business license or business tax certificate, even if you work from home. Fees and renewal schedules vary, so contact the city or county clerk where you plan to operate. Some cities charge a flat annual fee; others calculate the tax as a percentage of gross receipts.
Certain professions also require a state-level occupational license through the California Department of Consumer Affairs. Regulated fields include accountants, architects, engineers, barbers and cosmetologists, contractors, private investigators, and healthcare providers ranging from nurses to physicians. If your work falls under one of these boards, you need the professional license before taking on clients, regardless of your business structure.
Get Your Tax ID Numbers
If you form an LLC or corporation, you need a federal Employer Identification Number (EIN) from the IRS. Sole proprietors can technically use their Social Security number, but getting an EIN is free and keeps your SSN off invoices and tax forms sent to clients. The application takes a few minutes on the IRS website, and the number is issued immediately.9Internal Revenue Service. Get an Employer Identification Number
Planning to hire employees or subcontractors? You must register with the California Employment Development Department within 15 days of paying more than $100 in wages during a calendar quarter. The EDD issues an eight-digit state employer account number used for payroll tax reporting.10Employment Development Department. Am I Required to Register as an Employer? Solo contractors with no employees skip this step.
Set Up Quarterly Tax Payments
No client will withhold taxes for you. You owe both income tax and self-employment tax, and you pay them yourself throughout the year.
Self-Employment Tax
Self-employment tax covers Social Security and Medicare. The combined rate is 15.3%: 12.4% for Social Security, 2.9% for Medicare. You pay both the employee and employer halves. For 2026, the Social Security portion applies to net self-employment income up to $184,500. Medicare applies to all earnings with no cap.11Internal Revenue Service. Publication 15-A (2026), Employers Supplemental Tax Guide12Social Security Administration. Contribution and Benefit Base You can deduct half of your self-employment tax when calculating your adjusted gross income, which softens the hit.
Federal Estimated Payments
If you expect to owe $1,000 or more in federal tax for the year after subtracting withholding and credits, you must make quarterly estimated payments.13Internal Revenue Service. Form 1040-ES (NR) – 2026 The 2026 deadlines:
- First quarter: April 15, 2026
- Second quarter: June 15, 2026
- Third quarter: September 15, 2026
- Fourth quarter: January 15, 2027
Miss a deadline and you owe an underpayment penalty, calculated as interest on what you should have paid. The IRS doesn’t send reminders. Tracking the dates is on you.14Taxpayer Advocate Service. Making Estimated Tax Payments
California Estimated Payments
California has its own estimated tax requirement. If you expect to owe at least $500 in state income tax for the year, you pay quarterly to the Franchise Tax Board. The deadlines match the federal dates, but the amounts are split unevenly: 30% with the first payment, 40% with the second, nothing with the third, and 30% with the fourth.15Franchise Tax Board. Estimated Tax Payments That front-loaded schedule catches many first-year contractors off guard.
Know When Clients Will 1099 You
When a business pays you $2,000 or more in the tax year, it must report those payments to the IRS on Form 1099-NEC. The threshold rose from $600 starting with the 2026 tax year and will be adjusted for inflation in future years.16Internal Revenue Service. Publication 1099 General Instructions for Certain Information Returns
The 1099-NEC is an information return, not a tax bill. It tells the IRS how much a particular client paid you, and you should receive a copy by January 31 of the following year. Even if a client pays you less than $2,000 and doesn’t issue a 1099, you still owe taxes on that income. The reporting threshold governs what the client must file, not what you must report. Every dollar of self-employment income belongs on your tax return regardless of whether you received a form for it.
Decide on Insurance
California law requires every employer to carry workers’ compensation insurance, but the definition of employer matters. If you work solo with no employees, you’re generally not required to purchase workers’ comp for yourself.17CA.gov. Do I Have to Have Workers’ Compensation Insurance? The moment you hire anyone, even part-time, you must obtain coverage immediately.
Beyond workers’ comp, many contractors carry general liability insurance to protect against claims of property damage or bodily injury caused during their work. Some clients require proof of liability coverage before they’ll engage you. Professional liability insurance, sometimes called errors and omissions coverage, protects against claims that your work product caused a client financial harm. Neither type is legally required for most independent contractors, but going without them gets more expensive the larger your contracts become.
