How to Start an LLC in California in 2026: 8 Steps

What a California LLC actually is, and why founders choose it

A limited liability company is a hybrid legal structure: it gives its owners, called members, the personal liability protection of a corporation while letting profits and losses pass through to their personal tax returns like a partnership or sole proprietorship. California did not invent the LLC (Wyoming did, in 1977), and California's version, governed by the California Revised Uniform Limited Liability Company Act, is not chosen for the reasons founders pick Delaware. Most California LLCs are formed by people who already live and work there, for reasons that are practical rather than strategic. First, if your business operates in California, meaning you have an office, employees, or regular in-person activity there, you owe California's fees and taxes regardless of where you incorporate. Forming in Delaware and then registering as a foreign LLC in California means paying both states, so most single-state California businesses just form directly at home. Second, California's Revised Uniform Limited Liability Company Act gives members real flexibility to set their own rules in the operating agreement, and unlike Delaware, California actually requires every LLC to have one, whether written or oral, from the day it forms. Third, an LLC keeps your personal assets separate from business debts and lawsuits in a way a sole proprietorship never can, which matters more in a state with California's litigation volume than almost anywhere else. There is a cost to know about going in, not just a benefit. Every California LLC, active or dormant, owes an $800 minimum annual tax to the Franchise Tax Board for as long as it exists, and step 7 of this guide covers exactly when that first payment is due. None of this requires a lawyer to get started, though step 4 covers when hiring one is worth it. What California does require is the eight steps below, done in order.

Who can't form an LLC in California: licensed professionals

California is one of a handful of states that blocks licensed professionals from using an LLC at all for their licensed practice. Doctors, lawyers, accountants, architects, and several other licensed occupations cannot render professional services through a California LLC under the Revised Uniform Limited Liability Company Act's professional-services exclusion. If your business requires a state license to practice, check California's specific rule for your profession before you file anything. Most licensed professionals in California use a professional corporation or a registered limited liability partnership instead, both of which follow a different formation path than the one in this guide. This restriction is unusual. Most states, including Texas and Florida, allow at least some licensed professions to use an LLC, sometimes with a "professional LLC" designation. California simply does not extend that option to state-licensed practices, so confirm this before you spend time on the steps below if you are a licensed professional.

LLC vs. C corp vs. S corp vs. sole proprietorship

Before you file anything, it helps to know what you are actually choosing between. California lets you form several kinds of entities, and this guide is specifically about forming a limited liability company. Here is how an LLC compares to the three structures founders ask about most, side by side.

The short version: an LLC is the flexible, low-maintenance option for a business that plans to keep its profits, or split them among a small group of owners, rather than raise institutional money. A sole proprietorship costs nothing to start, but it leaves your personal assets exposed to business debts and lawsuits, which is the main reason most founders outgrow it within their first year or two of real revenue. An S corporation is not a separate entity you form at the state level. It is a tax election you file on top of an LLC or a corporation, using IRS Form 2553. Electing S corp status can lower self-employment tax for a profitable, owner-operated business, but it adds payroll requirements, a reasonable-compensation test, a 100-shareholder cap, and a single class of stock, which rules out most venture rounds. Our guide on whether your LLC counts as an S corp or a C corp walks through the mechanics. A C corporation becomes the default choice once venture capital enters the picture. Venture funds are structured to buy preferred stock, and most cannot legally invest in a pass-through LLC at all. A C corp also supports employee stock option pools and Qualified Small Business Stock (QSBS), a federal tax benefit that can shelter a meaningful share of gain on a future sale. The tradeoff is double taxation: the corporation pays tax on its profits, and shareholders pay tax again on any dividends. Almost every venture-backed startup that incorporates ends up doing so in Delaware rather than California, regardless of where its team actually sits, because investors expect it. Our Delaware C corp guide and our C corp vs. S corp comparison cover that decision in full. If a Delaware C corp turns out to be the better fit for your business, Rho Incorporation handles attorney-reviewed Delaware C corp formation for a $400 fee, credited back once you deposit $10,000 of new money into your Rho checking account and keep your daily average balance $10,000 above where it started for the 60 days after you incorporate. Your SS-4 is prepared and submitted for you, the first year of registered agent service is included, and you get same-day access to Rho banking once your incorporation is approved. Rho Incorporation currently supports Delaware C corporations, with LLC support coming soon. If you are comparing formation providers generally rather than deciding between entity types, our breakdown of the cheapest incorporation services ranks the true, all-in cost of each option.

What you need before you start

Gather these before you open the first form, and the eight steps below go much faster:

• A cleared LLC name that includes an LLC designator and has passed a search through bizfileonline.sos.ca.gov.

• A registered agent for service of process with a physical California street address, lined up and confirmed before you file.

• A payment method for the $70 state filing fee, plus any expedite fee you decide to pay.

• The responsible party's SSN or ITIN if you have one, so you can get an EIN online in minutes once the LLC is approved; otherwise, budget extra time for Form SS-4 by fax or mail.

• A plan for your operating agreement. California requires every LLC to have one, even a simple single-member one, from the day it forms.

• Clarity on where you actually operate, so you know at filing time whether step 8's foreign-qualification requirement will apply to you in any other state.

The 8 steps to start a California LLC

Each step below builds on the one before it. Do them out of order and you will find yourself stuck: you cannot open a bank account without an EIN, you cannot get an EIN in most cases without an approved Articles of Organization, and you cannot file the articles without a registered agent already lined up. Follow the sequence and there is nothing to redo.

1. Search your LLC name

Start with the free entity name search on bizfileonline.sos.ca.gov, the California Secretary of State's only official filing portal. Your name must be distinguishable on the record from every entity already on file in California, and it must include a designator such as "LLC" or "L.L.C." California's matching logic, like Delaware's, ignores punctuation, spacing, and generic words, so a name that reads as unique to you can still bounce back as a conflict at filing. Search a few variations before you settle on one, including a version without your designator and a version with common words stripped out, since near-matches get rejected at the filing stage rather than at the search stage. California does not currently offer a formal name reservation for LLCs the way some other states do for corporations, so most founders search and file in the same sitting once a name clears. Check domain and trademark availability at the same time if the brand name matters as much as the legal name, since a cleared entity name grants neither.

2. Appoint a California registered agent

Every California LLC must continuously maintain an agent for service of process: a person or company with a physical California street address, available during business hours, to accept lawsuits and official state mail on the LLC's behalf. A P.O. box does not qualify. If your LLC is ever sued, the registered agent is where the paperwork legally lands, so this is not a role to leave unmanaged. You can serve as your own agent if you have a California street address, and either an individual member or a registered corporate agent (a company that has filed Form 1505 with the Secretary of State to act as one) can fill the role. Almost every founder without a California address hires a commercial agent instead. Pricing typically runs $50 to $300 per year depending on the provider and whether it bundles compliance reminders, mail scanning, or a business address you can also use elsewhere. This pricing is set by each individual provider, not by the state of California. Choose your agent before you file, because the Articles of Organization require the agent's name and California address. Switching agents later is possible but means filing a change-of-agent form with the state, which carries its own fee, so getting this right up front saves a second filing. Look for a provider with a track record of forwarding notices promptly. A missed Franchise Tax Board notice or lawsuit notification because an agent sat on mail is a preventable, expensive mistake.

3. File the Articles of Organization

The Articles of Organization is the document that legally creates your LLC. It asks for your LLC's exact name, its principal office address, its registered agent's name and California address, and management structure (member-managed or manager-managed). You file primarily online through bizfileonline.sos.ca.gov, the state's official portal, which is also the fastest route. A formation service or your registered agent can also prepare and submit it for you, for a service fee layered on top of the state's own charge. The table below is the current fee schedule for a California LLC's Articles of Organization and its most common expedite options, sourced directly from the Secretary of State's published fee and service-option pages as of August 2026.

A few things founders miss on this table. First, California's expedite fees are steep compared to most states, which is part of why most founders simply file standard online and plan around a few business days rather than paying for speed. Second, the 4-hour tier requires prior preclearance, an extra $500 step, so the realistic cost of same-morning turnaround is closer to $1,000 all in once you add both fees together. Third, California's processing times are not fixed; the Secretary of State publishes a live "Current Processing Dates" page that moves with filing volume, and it commonly stretches past the multi-day range shown above around fiscal year-end and calendar year-end. Check it immediately before you file rather than relying on any single published estimate, including this one. Most founders do not need to pay for speed. The expedited tiers exist mainly for situations with a hard external deadline, closing a bank account before a specific date or meeting a contract's incorporation clause, rather than everyday convenience. Weigh the $350 to $750 expedite fee against how much that specific deadline is actually worth to you.

4. Adopt an operating agreement

Unlike Delaware, California does not treat the operating agreement as optional. The California Revised Uniform Limited Liability Company Act requires every LLC, including single-member LLCs, to adopt one, written or oral, and a written one is strongly preferable if you ever need to prove its terms to a bank, an investor, or a court. You do not file the operating agreement with the state; it stays a private document between members. It sets ownership percentages, capital contributions, voting rights, how profits and losses get allocated, what happens if a member leaves, dies, or becomes incapacitated, and how disputes between members get resolved. California courts will generally enforce whatever the members agreed to in writing, which is a feature, but it also means a generic template downloaded without review can lock in terms nobody actually wants once a real dispute arises. An operating agreement is also one of the clearest pieces of evidence that your LLC is a genuinely separate legal entity from you personally, which matters if a creditor or plaintiff ever tries to pierce the corporate veil and go after your personal assets. Banks and future investors will ask to see it before opening accounts or writing checks. Have a lawyer review anything beyond a plain, single-member structure, especially once you have multiple members with different contribution types, unequal ownership splits, or any plan to bring in outside capital later.

5. Get an EIN from the IRS

Your Employer Identification Number (EIN) is the federal tax ID you will use to open a business bank account, hire employees, file taxes, and sign most vendor and payment-processor agreements. It is free directly from the IRS, so never pay a third party's "EIN filing fee" for the number itself. That fee is for someone else's paperwork handling, not for the EIN, which the IRS never charges for. If the LLC's responsible party has a Social Security Number or Individual Taxpayer Identification Number, apply online at irs.gov and receive the EIN immediately, the same session, no waiting. If you are a non-US founder without either, you apply by fax or mail using Form SS-4, since the IRS's online EIN tool requires a US taxpayer ID for the responsible party. That paper route can take several weeks rather than minutes, so plan around it if you are racing a deadline. A multi-member LLC needs an EIN regardless of how it plans to be taxed. A single-member LLC technically does not need one to exist, the IRS lets it use the owner's SSN by default, but you will need one anyway the moment you want to open a business bank account, since virtually no bank will open one on a personal SSN alone. Get the EIN as soon as your Articles of Organization is approved, rather than waiting until you are standing at the bank. Keep the IRS's confirmation letter (the CP 575 or 147C) somewhere safe.

6. Open a business bank account

Keeping business money separate from personal money is not optional for an LLC, it is the operational habit that makes your liability protection real rather than theoretical. Commingling funds, paying personal expenses from the business account or vice versa, is the single fastest way for a court to disregard the LLC entirely and treat you as personally liable for its debts. Once your Articles of Organization is approved and your EIN has arrived, opening a dedicated account should be one of your very first moves. Rho offers business checking built for companies that want more than a place to park cash: corporate cards with up to 2% cashback with Rho Platinum (terms apply), on up to $1M in eligible annual card spend, 1.25% standard, plus treasury, expense management, and invoicing on one platform. The application takes under 10 minutes, and approval does not depend on your entity type, a California LLC, an LLC formed anywhere else, or a Delaware C corp can all apply. Rho Incorporation currently supports Delaware C corporations, with LLC support coming soon, but banking for your LLC is available today regardless. Whatever bank you choose, confirm what it needs before you show up: most require the approved Articles of Organization, the EIN confirmation letter, a government-issued ID for each authorized signer, and sometimes the operating agreement itself. Having all four ready in one folder turns account opening into a same-day task instead of a multi-visit one.

7. Pay the $800 annual tax, the LLC fee if it applies, and file your Statement of Information

California LLCs carry more recurring obligations than Delaware LLCs, and this is the step founders most often underestimate going in. Every California LLC, active or inactive, owes an $800 minimum annual tax to the Franchise Tax Board (Revenue and Taxation Code section 17941), regardless of income. The first year's payment is due by the 15th day of the 4th month after you file, using Form 3522, and every year after that it is due by April 15. A previous first-year exemption under AB 85 applied only to LLCs organized between 2021 and the end of 2023; it has expired, and any LLC formed today owes the full $800 in its first year. On top of the flat $800, an LLC with California-source gross receipts of $250,000 or more owes an additional income-based fee, filed on Form 3536 as an estimate and Form 3537 with the return:

Separately from the Franchise Tax Board, California LLCs also owe a Statement of Information (Form LLC-12) to the Secretary of State, due within 90 days of formation and every two years afterward, for a $20 filing fee. Missing it draws a $250 penalty on top of the fee itself. Put these dates on your calendar the day your LLC is approved, not the week before they hit:

• The 15th day of the 4th month after formation: your first $800 annual tax payment, and every April 15 after that.

• Within 90 days of formation: your first Statement of Information, then every two years on the same cycle, $20 each time.

• Any additional LLC fee tier deadline, if your gross receipts cross $250,000, estimated during the year on Form 3536 and reconciled on Form 3537.

• Your registered agent renewal date, separate from any state deadline.

• April 15 (typical): federal tax filing for LLCs taxed as partnerships or disregarded sole proprietorships, plus your California personal income tax return.

An LLC that falls behind on these can lose its right to sue in California court and can be suspended by the Franchise Tax Board, which blocks financings, contracts, and expansion until it is brought current.

8. Register as a foreign LLC if you also operate in other states

Most California LLCs are formed by people who live and operate in California, so this step applies less often here than it does for an out-of-state Delaware entity. But if your California LLC also has an office, employees, or regular in-person operations in another state, you typically must register there as a foreign LLC, on top of staying current in California. That triggers a second filing fee set by that state, often a second registered agent, and a second set of ongoing fees and reports running alongside California's own $800 tax and Statement of Information. This is the step founders skip most often when they expand into a second state after forming in California, usually because nobody explains it during the excitement of opening a new office. Skipping it risks fines, back taxes, and, in some states, losing the right to enforce contracts there until you register. If you will only ever operate in California, you can ignore this step entirely; it only applies once your business has a genuine physical presence somewhere else.

What a California LLC actually costs in year one

Add up every line from this guide and a typical California LLC, formed with standard (not expedited) processing and under the $250,000 gross-receipts threshold for the additional LLC fee, costs roughly $890 to $1,140 in its first twelve months, depending on which registered agent you pick. Here is the full breakdown:

Every year after the first drops the $70 formation fee and, in most years, the $20 Statement of Information fee (it is only due every other year), leaving the $800 annual tax as the dominant recurring cost of keeping a California LLC in good standing. That figure does not include any other state's foreign-qualification fees and annual reports if step 8 applies to you, or the additional LLC fee if your gross receipts grow past $250,000.

What it costs to form the same LLC through a formation service instead

The state fee above is fixed no matter who files it for you. What changes is whether you pay a formation company on top of it, and what that company charges once the registered agent renews. The table below prices out a California LLC across the most common routes, using each provider's own published pricing.

Rho Incorporation is not an LLC formation option today, which is why it appears here as the C-corp alternative rather than a line-item competitor to ZenBusiness or LegalZoom on an LLC filing. If a Delaware C corp fits your plans better than a California LLC, and it usually does once outside investors enter the picture, this is the column to look at; if an LLC is the right call for your business, DIY or a budget formation service will beat all four of Rho's numbers on a pure LLC filing, since Rho does not currently file LLCs in any state. For the fuller ranking across every major formation provider, our breakdown of the cheapest incorporation services goes deeper on renewal pricing and the upsells to watch for.

Common mistakes to avoid when forming a California LLC

Most California LLC formations that go wrong fail in one of these six places. Checking this list against your own filing takes a few minutes and can save weeks of cleanup later.

• Assuming the $800 annual tax is prorated or waived in year one. It is neither, for any LLC formed today; the first-year exemption expired at the end of 2023, and the tax is due by the 15th day of the 4th month after you file regardless of income or activity.

• Skipping the Statement of Information deadline. The 90-day initial filing and the two-year renewal are easy to lose track of since they run on a different clock than the annual tax; missing either draws a $250 penalty.

• Treating the operating agreement as optional paperwork. California law requires every LLC to have one, and Delaware-style advice that calls it optional does not apply here.

• Forming as a licensed professional. If your practice requires a state license, an LLC may not be available to you at all under California's professional-services exclusion; confirm this before you file, not after.

• Commingling personal and business funds from day one. Using a personal account for the LLC's first few transactions "just until the business account is open" is one of the most common ways new owners accidentally undermine their own liability protection.

• Ignoring the income-based LLC fee until it's too late. An LLC that crosses $250,000 in California gross receipts owes the additional fee on top of the flat $800, estimated during the year rather than settled after the fact; founders who forget this get a larger, unplanned bill.

• Assuming a name that cleared a quick web search will also clear at filing. California's matching algorithm on bizfileonline.sos.ca.gov ignores punctuation and generic words, so run the actual search on the state's own portal immediately before you file rather than trusting an earlier check.

Two more California registrations that trip founders up

The eight steps above form the LLC itself, but two additional California registrations catch founders off guard because neither one comes from the Secretary of State or the Franchise Tax Board. If you plan to hire employees, you must register with California's Employment Development Department (EDD) before your first payroll run, which is separate from your EIN and separate from your LLC filing. The EDD assigns its own account number, handles state payroll tax withholding, and expects registration within 15 days of paying more than $100 in wages in a calendar quarter. Skipping this step does not delay payroll, it just surfaces later as penalties once the state notices unregistered wages. If your LLC sells or leases tangible goods in California, you need a seller's permit from the California Department of Tax and Fee Administration (CDTFA), which is free to obtain but carries real consequences for skipping it: selling taxable goods without a permit is a misdemeanor under California law, on top of the sales tax you would owe regardless. Service businesses with no physical product to sell typically do not need one, but check the CDTFA's own guidance if your business sits anywhere near that line, for example a consultancy that also sells a physical workbook or kit. Neither of these registrations replaces or changes anything from the eight steps above; they run in parallel once your LLC actually starts operating, and both are free to register for even though the underlying tax obligations are not.

After the paperwork: run it like a company

Once the LLC exists on paper, the habits matter more than the documents ever will. Keep business and personal finances strictly separate, sign every contract in the LLC's name rather than your own, keep your registered agent's information current with the state, and pay the $800 annual tax and any income-based fee on time every year without exception. These habits, done consistently, are what actually preserve the liability protection you formed the LLC to get in the first place. Rho gives California LLCs a full financial stack from day one: business checking, corporate cards, treasury, expense management, and invoicing, all on one platform, so the operational side of running the company is handled the same day your EIN arrives. And if your business outgrows the LLC structure down the line, whether that means bringing on outside investors or wanting the option pool and QSBS benefits a C corp offers, Rho Incorporation is there as the Delaware C-corp path when you decide that fits, with LLC support coming soon for founders who want to start there directly. If you are weighing California against other high-volume formation states rather than assuming California is the right call, our guides to starting an LLC in Texas and starting an LLC in Florida cover the same eight steps for those states, and our Delaware LLC formation guide covers the classic out-of-state option most venture-track founders end up choosing instead. Revisit this guide each time something changes: a new member joins, your gross receipts cross a fee tier, or you start selling into a new state. The eight steps above only happen once, but the decisions behind them, which entity, which state, when to convert, are worth re-checking as the business grows rather than assuming the choice you made at formation is permanent.
