Business Formation in San Diego: LLCs, Corporations, and Partnerships
Starting a business involves much more than filing paperwork with the Secretary of State. The structure you choose affects your personal liability, your taxes, and how easily you can bring in partners, raise money, or sell later.
We help you choose the right structure and set it up properly from day one.

How We Help You Set Up Your Business
Choosing a Structure
We help you pick the entity that fits your goals, industry, ownership, and growth plans.
Formation and Filing
We prepare and file your Articles of Organization or Articles of Incorporation.
Operating Agreements and Bylaws
We draft the documents that set out who owns what and how decisions get made.
Ownership Planning
We plan founder, partner, and ownership terms, including voting rights and what happens if someone leaves.
Be Compliant
We guide you on your EIN, required filings, and record-keeping so the business starts on solid ground.
Who This Is For
- Licensed professionals, such as doctors, dentists, and accountants, who may need a professional corporation
- Co-founders and partners who want clear ownership terms from the start
- Entrepreneurs starting their first business
- Property owners who want to hold real estate in an entity
- Side businesses that are ready to become official
- Existing businesses that want to change or clean up their structure. If that is you, see our Business Check-Up.
Why Your Structure Decision Carries Real Weight
Forming a company can take an afternoon. Living with those choices can take years. Your entity and your agreements decide who owns what, who makes decisions, how profits are shared and what happens when something changes. When those answers are missing or vague, California’s default rules fill the gaps, and they rarely match what the owners had in mind.
The cost of getting it wrong usually shows up at the worst moment. A co-founder walks away still holding half the company. An investor’s lawyer finds that key intellectual property was never assigned to the business. A buyer’s due diligence turns up missing records, and the price drops or the deal stalls. Fixing structure later can mean restating ownership, amending tax filings and negotiating with people whose interests have changed. That often costs far more than planning it up front.
For example, two friends form an LLC online and split ownership evenly. Two years in, one of them steps back to take a full-time job but keeps half the company. With no vesting schedule and no buyout terms, the partner still doing the work has limited options, and major decisions may still need the absent owner’s signature.
Consider a common situation: a founder builds software or a brand before forming the company, then brings in money from friends or an angel investor. If the founder never signed an assignment moving that work into the company, the company may not clearly own its most valuable asset. Investors and buyers look for this gap.
Careful business formation work in San Diego, or anywhere in California, gives you clear ownership, clear decision rights and a paper trail that holds up when someone else is reviewing it.
Which Structure Fits Your Business?
There is no single right answer. It depends on who owns the business, how it will make money, and where it is headed. Here is a quick overview. For more detail, read our guides: How to Form an LLC in California and S-Corp vs. LLC in California.
Limited Liability Company (LLC)
A flexible structure that separates your personal assets from the business when it is set up and run properly. Many small businesses start here.
Corporation
A structure built for issuing shares, bringing in investors, and planning for growth, with more formal rules for directors, officers, and meetings.
S corporation tax election
Not a separate type of entity. It is a tax choice an LLC or corporation can make, and it can make sense at certain income levels. We recommend reviewing it with your CPA.
Professional corporation
In California, many licensed professionals cannot use an LLC for their practice and need a professional corporation instead. Read more: Your California Practice Probably Can’t Be an LLC.
Partnership
Two or more owners sharing a business. A written partnership agreement matters, because default rules may not match what the partners expect.
Nonprofit
For organizations with a charitable or public purpose, with separate state and federal requirements.
California Rules Worth Knowing
- Minimum annual tax. Most LLCs and corporations in California owe an $800 minimum franchise tax each year, starting in the first year.
- Statement of Information. LLCs must file one with the Secretary of State every two years, and corporations every year. Missing it can lead to penalties.
- Keeping protection in place. The liability protection only works if the business is run as a separate entity. See 5 Ways Founders Accidentally Weaken Their Own LLC.
Mistakes We Help Owners Avoid
Most of these problems are quiet at first and costly later.
- Relying on a template operating agreement. Online filing services can produce an operating agreement, but it is usually generic. It may not address decisions, an owner’s death or divorce, or how a departing member gets paid. Your agreement should reflect how your business actually runs and who you are in business with.
- Splitting equity with no vesting. Giving each co-founder a fixed share on day one feels fair until someone stops contributing. Vesting lets ownership build over time, so a founder who leaves early keeps only what they earned. Without it, the people still working may carry a partner who has moved on.
- Skipping buy-sell terms. Every owner eventually leaves, whether through a sale, retirement, disability, death or a falling out. Buy-sell provisions set the rules in advance: who can buy the departing owner’s interest, how it is valued and how it gets paid for. Negotiating those terms in the middle of a dispute is much harder.
- Leaving IP and key assets outside the company. Software, a brand name, customer lists and even a domain name often start out in a founder’s personal name. If they are not formally contributed or assigned to the company, ownership can be unclear. That gap can complicate financing, a future sale or a split between founders.
- Mixing personal and business money. Paying personal bills from the business account, or business costs from your own card, blurs the line between you and the company. That blurring can put the liability protection your company is supposed to provide at risk. A creditor may argue the company is not really separate from you and try to reach your personal assets, which is called piercing the corporate veil. A separate bank account and clean records are simple habits that matter.
- Choosing a structure for today only. The entity that suits a solo side business may not suit a company planning to raise outside money or sell someday. Some investors prefer a corporation, and converting later can create tax and paperwork costs. We plan for where you want to be in several years.

- The name of every owner and the percentage each expects to hold
- What each owner is contributing: cash, property, equipment, intellectual property or time

- Any professional licenses involved, such as medical, dental, legal, accounting or contracting

- Leases, contracts or loan documents already signed in your personal name
- Business names you want to use, including any fictitious business name (DBA)
Working With Your CPA, Banker and Other Advisors
Forming a business is part legal decision and part tax decision. If you have a CPA, we work with them from the start so the entity, tax election and ownership terms line up. Your banker will ask for formation documents and an EIN before opening accounts or extending credit, and we can prepare what they need. If the business will hold real estate, we coordinate with your lender and your title or escrow officer on how title is held. Your insurance agent should know about the new entity so policies name the right insured. We handle the legal side and keep your team informed.
Fees
Where possible, we offer a fixed fee for business formation, so you know the cost up front. Before quoting, we ask a few questions about your business and what you need. See our fees page for how we price legal work.
Common Questions
Answers to what business owners ask most before forming an entity.
Do I need a lawyer to form an LLC?
You can file the forms yourself. The value of working with an attorney is choosing the right structure, drafting an operating agreement that fits your situation, and avoiding mistakes that are costly to fix later.
Should I be an LLC or an S corporation?
An S corporation is a tax election, not a separate entity, and whether it helps depends on your income and situation. We explain the legal side and recommend reviewing the tax side with your CPA.
How long does it take?
Timing depends on the Secretary of State’s processing times. We will tell you what to expect when we start.
Can you help an existing business change its structure?
Yes. We help businesses move from a sole proprietorship or partnership to an LLC or corporation, and clean up documents that were never finished.
Can you work with my accountant?
Yes. We can coordinate with your CPA and introduce you to other professionals your business may need.
Is an online LLC filing service enough for my business?
For a single owner with a simple, low-risk business, it can be. What an online service usually does not do is advise you on structure or tax elections, or draft an operating agreement built around your partners, vesting, buyouts and decision-making. With co-founders, investors or meaningful revenue, those terms are where much of the value and risk sit.
What happens to my ownership if a co-founder leaves the company?
It depends on what your operating or shareholder agreement says. If it includes vesting and buy-sell terms, those rules decide whether the departing founder keeps their interest, must sell it back and at what price. If the agreement is silent, the departing founder may keep their full stake, and default rules under California law fill in the rest. Setting these terms at formation is far easier than negotiating them later.
Should my LLC be member-managed or manager-managed?
It depends on who will actually run the business. In a member-managed LLC, the owners run the company together and can generally act on its behalf. In a manager-managed LLC, the owners appoint one or more managers, and other members act more like passive investors. Manager-managed often fits companies with silent investors or family owners. Your operating agreement should spell out each person’s authority either way.
Do I need to register my out-of-state LLC to do business in California?
In many cases, yes. An LLC or corporation formed in another state, such as Delaware, Nevada or Wyoming, that is doing business in California generally must register with the California Secretary of State and is typically subject to the same $800 minimum annual tax. We can review whether registration applies to you and handle the filing.
