How to Register a California LLP — Step-by-Step

Before anything else, confirm that your group is eligible. California does not allow just any business to register as an LLP. The structure is reserved for partnerships practicing law, public accountancy, architecture, or engineering and land surveying in the arrangements the Corporations Code permits. Each partner must hold the relevant professional license.

If your practice qualifies, sketch out the basics with your partners before you file:

• Who the partners are and whether everyone is properly licensed
• The partnership's name and the profession it will practice
• The principal office address in California
• Who will serve as your agent for service of process
• How you'll satisfy the security-for-claims requirement — professional liability insurance, a bond, or set-aside funds

Getting these settled first means the actual filing goes quickly. If your group isn't a qualifying professional practice, stop here — you'll want a limited liability company or a limited partnership instead, and registering an LLP won't be an option.

Your LLP's name must be distinguishable from every other business name already on record with the California Secretary of State. Search your proposed name and close variations at the bizfile Online business search. Look for anything that reads or sounds too similar — the state compares against all entity types on file, not just LLPs.

California LLP naming rules

• The name must contain "Registered Limited Liability Partnership," "Limited Liability Partnership," "R.L.L.P.," "L.L.P.," "RLLP," or "LLP"
• It must be distinguishable from existing names on the state's records
• It cannot include words implying a purpose the partnership isn't authorized to pursue, or a government affiliation it doesn't have
• Because LLPs are professional practices, the name should be consistent with the naming conventions your licensing board expects for firms in your field

If your firm plans to operate under a name other than its registered legal name, you'll register a fictitious business name at the county level with the County Clerk-Recorder — that is a separate process from registering the LLP, and it includes a newspaper publication step in most counties.

Every California LLP must name an agent for service of process — California's term for what most states call a registered agent — and keep one on file for the life of the partnership. This is the person or company that receives lawsuits, subpoenas, and official state correspondence on the partnership's behalf.

Who can serve

• An individual who resides in California and has a physical California street address
• A registered corporate agent — a company qualified with the Secretary of State to act as an agent, which lists its own address rather than a partner's

A P.O. box does not satisfy the requirement; the agent needs a physical street address where documents can be delivered during business hours. Many firms use a commercial agent so that no partner's home address appears in the public record and so someone is reliably available to accept service even when the office is closed. If you use a partner's address, understand that it becomes searchable in the state's public database.

Form LLP-1, the Application to Register a Limited Liability Partnership, is the filing that creates your LLP in California's official records. You submit it online through bizfile Online. California has moved most business filings online, so plan to file electronically rather than by mail.

What the application asks for

• The partnership's name, with the required LLP designator
• The profession the partnership will practice (law, accountancy, architecture, engineering/land surveying)
• The principal office address and mailing address
• The agent for service of process — name and California street address
• A statement electing limited liability partnership status

Once the state accepts the filing, the partnership carries the LLP designation and its liability shield. Processing typically runs a couple of business days for online filings, though state workload varies. If you have a time-sensitive deadline — a client engagement, a lease, a bank account — file early and give the Secretary of State room to process it.

The partnership agreement is your LLP's internal governing document. California doesn't require you to file it with the state, and it never goes into any public database — but you should have a written agreement in place before you take on clients or open accounts. Without one, California's statutory default rules for partnerships govern everything, and those defaults rarely match what a professional firm actually intends.

What a complete partnership agreement covers

• Capital contributions — what each partner put in and what future contributions are owed
• Profit and loss allocation — how income is split, which often differs from a simple equal division in a professional firm
• Draws and guaranteed payments — how and when partners are paid
• Management and voting — who decides what, and which decisions require a full partner vote
• Admitting and withdrawing partners — the process for bringing in a new partner or handling a departure, retirement, or death
• Dispute resolution and dissolution — how disagreements are resolved and how the firm winds down if it ends

For a professional LLP, the agreement is where you address issues unique to your field: how client relationships are handled when a partner leaves, how the firm meets its security-for-claims obligation, and how licensing status affects partnership rights. Have your attorney draft or review it.

An Employer Identification Number — the nine-digit federal tax ID the IRS provides free of charge — is something a multi-member entity like an LLP always needs — the partnership uses it to file its partnership return, open bank accounts, and hire employees.

Applying for the EIN

Apply online through the IRS EIN Assistant at IRS.gov. Expect the form to take roughly ten minutes; the IRS assigns the number on the spot, letting you print the confirmation and put it to use that same day. The online application requires a US Social Security number or ITIN for the responsible party; applicants without one apply by fax or mail using Form SS-4.

Opening the account

Keeping partnership finances entirely separate from personal finances is essential — commingling undermines the liability protection you registered for. To open an LLP bank account, most banks ask for the filed Form LLP-1 confirmation, the EIN letter, the partnership agreement, and ID for the authorized signers. Bring all four to avoid a second trip.

Most of the work is front-loaded in registration. After that, a California LLP has a handful of recurring obligations.

Statement of Information

California LLPs file a Statement of Information with the Secretary of State on a biennial cycle, submitted through bizfile Online. It updates the state's record of your partnership's addresses and agent for service of process. It is not a financial disclosure. Missing it can lead to a delinquency notice and, eventually, loss of good standing.

Annual tax

California charges every LLP an annual tax paid to the Franchise Tax Board, due regardless of profit. The partnership also files a California partnership return (Form 565) and federal Form 1065, issuing Schedule K-1s to the partners. Your CPA should own the tax calendar.

Maintained security

Keep your professional liability insurance, bond, or set-aside funds current at the level your profession requires. This is the condition California attaches to the LLP shield, and letting it lapse jeopardizes the protection.

Agent and address changes

If your agent for service of process changes, or your office moves, update the record promptly so the state always has a valid contact.
