How to Start a Business in California

Starting a business in California involves several important steps, from selecting the right idea to ensuring legal compliance. This simple “starting a business in California checklist” helps you plan, register, and launch your business with confidence.

Step 1: Choose a Business Idea

Before opening a business in California, you need a solid idea. But having an idea isn’t enough. You’ve got to ensure it works in real life. That’s called idea validation,which involves checking if people want what you’re offering, if they’ll pay for it, and if the market is not too crowded already. This helps you avoid wasting time and money on something that may not succeed.

California has many growing industries, which makes it easier to find a good niche. Some strong business areas right now include:

• Electric vehicle (EV) infrastructure.
• Clean energy.
• Eco-friendly construction.
• Green tech services.

These markets are experiencing rapid growth, thanks to state policies and public support for a cleaner future. If you’re still unsure about where to start, use simple tools and resources to help you brainstorm. You can:

• Explore Google Trends to see what people are searching for.
• Use keyword research tools to find in-demand topics.
• Visit business idea generators online.
• Look at local issues you could help solve.
• Talk to people in your area about what they need or want.

Choosing the right idea is the first big step. It sets the direction for everything that follows your brand, plan, and how you reach targeted customers. So, take your time and choose wisely.

Step 2: Name Your Business

Your business name is one of the first things people will notice. It should be simple to spell, easy to remember, and reflect what your business does. A good business name builds trust and makes your brand stand out. Try to avoid names that are too long or hard to say. Keep it short, clear, and creative.

Once you’ve thought of a few names, the next step is to check if they’re available. Start by searching the California Secretary of State’s business name database to ensure no one else is using the same name. After that, check the United States Patent and Trademark Office (USPTO) to see if the name or a similar one is already trademarked.

Before you finalize a business name, ensure you can secure the corresponding domain name. This is your website address. If someone else owns the domain for your chosen name, you should consider an alternative version. To quickly generate different variations, try Hosted.com®’s AI Domain Name generator.

Grab your desired name as soon as you find it, even before you finish registering a business in California. If your name is unique and available, you can reserve it with the California Secretary of State (SOS). This holds your business name for up to 60 dayswhile you complete the setup.

It’s a smart move if you’re not ready to launch but don’t want to lose the name to someone else. Taking the time to pick and protect the right name can help you start strong and grow with confidence.

Step 3: Create a Business Plan

A business plan is your roadmap. It enables you to stay organized, set clear goals, and make smart decisions. It’s also something many banks and investors ask for when you apply for a loan or try to raise money. Even if you’re funding the business yourself, having a plan gives you a clear path forward.

Your plan should start with your mission statement. This explains what your business does and why it exists. Next, include a market analysis. This means you’ve researched your industry and have identified your customers and competitors.

Then, focus on your financial plan. This lists your startup costs, expected income, and the amount of money you’ll need to run the business. It should also show how you plan to grow over time.

Finally, add your sales and marketing strategy. This covers how you’ll reach your customers, what channels you’ll use (online, in person, or both), and how you plan to sell your product or service.

Your business plan doesn’t have to be long or complicated. However, it should cover the most important points in a clear and easy-to-follow manner. With a solid plan in place, you’ll be more confident and prepared as you move forward.

Step 4: Select a Business Structure

Picking the right business structure is a big decision. It affects your taxes, daily operations, and the level of personal risk you take on. In California, the most common structures are:

• Sole Proprietorship.
• Limited Liability Company (LLC).
• Corporation.
• Limited Liability Partnership (LLP).

Each one has its pros and cons.

• SOLE PROPRIETORSHIP

This is the easiest to setup. You’re the only owner, and you keep all the profits. But there’s a catch; you’re personally responsible for any business debts or legal issues.

• LLC

An LLC gives you more protection. Your assets (e.g., your house or car) aren’t at risk if the business is sued. It’s a good choice for many small business owners because it’s simple to run and has fewer rules than a corporation.

• CORPORATION

A corporation offers the strongest legal protection, but it’s more complex. It requires more paperwork and strict record-keeping. Corporations are better for larger businesses or anyone planning to raise money from investors.

• LLP

An LLP is primarily used by professionals, such as lawyers or accountants, who want to collaborate while protecting their personal assets.

To choose the right structure, consider the amount of risk you’re comfortable with, your preferred tax approach, and the amount of paperwork you’re willing to handle. You can also talk to a tax advisor or lawyer to help you decide. Choosing the right setup from the start can save you time, money, and stress later.

Step 5: Fund Your Business

Every business needs money to get started and grow. The good news is that there are many ways to get funding when you start a business in California. Some people fund their business themselves (it’s called bootstrapping), but others need help from outside sources. You can consider:

• Small business loans.
• Grants.
• Investor/venture capital (VC).

Now, let’s understand each of these.

Loans from credit unions or banks are a common option. You’ll need to pay them back over time with interest. The Small Business Administration (SBA) also offers special loan programs with lower rates and flexible terms. These are great for first-time business owners.

Grants are another option, and the best part is that they don’t need to be paid back. In California, you can apply for local business grants, clean energy programs, and state-backed funding for startups. We recommend you check the following for current grant lists:

• California Office of the Small Business Advocate (CalOSBA)
• SBA.gov
• California’s IBank Small Business Finance Center

If you’re thinking about working with investors or VCs, you’ll need to pitch your business. This means sharing your idea clearly, in a way that shows why it’s worth the money. Ensure you have a strong:

• Business Plan.
• Clear Financial Projections.
• Plan to Grow.

Investors/VC want to know how they’ll earn their money back and when. Remember, when you work with a VC/Investor, they give you money in exchange for a share of your company. They often bring advice and connections, but you’ll be giving up some control.

Getting the right funding takes time and effort, but it’s a key step. With the right support, you’ll be able to cover your startup costs, hire help, and grow your business faster.

Step 6: Register a Fictitious Name (DBA)

If you plan to run your business under a different name than your legal name, you’ll need to register a DBA, which stands for Doing Business As. It’s also called a fictitious business name or trade name.

For example, if your legal business name is Green Energy Solutions LLC but you want to advertise as GreenGo Solar, you’ll need a DBA.

When you start a business in California, this process is handled at the county level, not by the state. You’ll need to check with your county clerk’s office to see the exact steps. Usually, it involves:

• Filling out a form.
• Paying a small fee.
• Publishing your new name in a local newspaper.

If you’re a Certified Public Accountant (CPA) or accounting professional, and you’re using a trade name, you’ll need to register your DBA with the California Board of Accountancy (CBA). The good news is that this step is free. Just ensure the name complies with CBA rules and isn’t misleading.

Registering a DBA lets you use your business name legally in marketing, contracts, and bank accounts. It also helps customers trust that your business is legitimate and properly established.

Step 7: Apply for an Employer Identification Number (EIN)

EIN is a unique number the IRS provides businesses. Think of it as a Social Security Number for your company. It’s used for filing taxes, opening business bank accounts, and hiring employees.

Even if you don’t plan to hire anyone right now, having an EIN makes it easier to keep your personal and business finances separate. Many banks won’t let you open a business account without it.

You can apply for an EIN online at the IRS website, and the process is free. To get started, you’ll need an Individual Taxpayer Identification Number (ITIN) or a Social Security Number (SSN). Once you fill out the form, you’ll receive your EIN immediately.

Getting your EIN is a quick but important step. It means your business is officially recognized by the federal government and simplifies everyday business tasks.

Step 8: Choose a Registered Agent & Register with the State

If you’re forming an LLC or corporation in California, one of the key steps is choosing a registered agent, who receives official documents for your business, which includes:

• Legal papers.
• Tax notices.
• State letters.

The agent must have a physical address in California and be available during normal business hours.

Remember, in California, you can’t name yourself as your personal registered agent if your business is a corporation or LLC. You can choose a trusted individual or pay for a professional registered agent service. These services are reliable and ensure you never miss important documents.

Once you’ve picked your registered agent, the next step is to register your business with the California Secretary of State. You’ll need to file the proper paperwork, either Articles of Organization for an LLC or Articles of Incorporation for a Corporation, which can be found on the website for California Secretary of State – Business Forms.

This can be done online, by mail, or in person. There’s also a filing fee, usually around $70 for an LLC.

After registration, your business becomes official in the state. You’ll receive confirmation documents, and you can then setup licenses, taxes, and other necessary details.

Step 9: Tax Registration & Compliance

Once your business is registered, it’s time to handle your taxes. California has its own tax rules, so setup everything correctly from the start.

First, if you start an LLC, corporation, or limited partnership in California, you’ll need to pay the franchise tax. This is a minimum of $800 per year, even if your business doesn’t make a profit. If you form a corporation, you may also owe state income tax, which depends on your earnings.

If you plan to sell products or offer taxable services, you’ll need a seller’s permit, which allows you to collect sales tax from customers. You can apply for it online through the California Department of Tax and Fee Administration (CDTFA). It’s free, but you must keep track of what you sell and pay the sales tax you collect to the state.

On the federal level, your business may need to pay income taxes and payroll taxes if you have employees. If you’ve already applied for an EIN, that’s the number you’ll use when filing your federal taxes with the IRS.

Tax compliance might sound confusing, but being organized from the start helps you avoid problems later. Keep good records, set reminders for deadlines, and consider using accounting software or hiring a tax pro to help you stay on track.

Step 10: Licenses & Permits

To run your business legally in California, you may need one or more licenses or permits. But remember, California doesn’t have a universal state business license. That means you won’t get a single license that will work for every business across the state.

Instead, the licenses you need will depend on:

• What does your business do?
• Where is it located?

For example, if you’re opening a restaurant, you may need a health permit from your county. If you’re selling alcohol, you will need a license from the Department of Alcoholic Beverage Control. If you’re working from home, your city may require a home occupation permit.

Because the rules vary, it’s important to check:

• State requirements.
• Local requirements.

One easy way to do this is by using CalGold, a free tool from the state of California. You enter your city and business type, and CalGoldshows you the permits and licenses you need, plus where to acquire them.

Getting the right licenses protects your business and helps you avoid fines or shutdowns. It also builds trust with your clients, showing them that you’re running a safe and legal operation.

Step 11: Insurance Options

Business insurance protects you from unexpected problems. Even if you’re careful, accidents can still happen, and without insurance, you may have to pay out of pocket.

One common type is general liability insurance. This covers incidents such as customer injuries or damage to someone else’s property. If somebody slips and falls at your store, this insurance helps cover the cost. If you have a team, workers’ compensation insurance is required when you start a business in California. It helps cover medical care if an employee is hurt on the job.

You may also need professional liability if you give advice or offer services. If you run a delivery service or use vehicles, consider commercial auto insurance.

Having the right coverage gives you peace of mind. It also makes your business look more trustworthy and professional, which is helpful when working with clients, landlords, or investors.

Step 12: Open Business Bank Account(s)

Opening a business bank account keeps your personal and business finances separate, which makes it easier to track expenses, file taxes, and present a professional image to customers.

To open one, you’ll need a few documents. Most banks ask for:

• Your Employer Identification Number.
• Your business formation papers (like your Articles of Organization or Incorporation).
• Your business license or permit.
• A copy of your DBA (if you use a trade name).

You may also apply for a business credit card, which helps build credit and keeps business purchases in one place. A dedicated account shows you’re serious about your business and makes managing money a lot simpler.

Step 13: Setup Your Website & Online Presence

Today, every business needs a strong online presence. The first step is getting a domain name, which is your website’s address (e.g., hosted.com). Pick one that matches your business name and is easy to remember.

After that, you’ll need web hosting to store your website and make it visible online. Once you’ve got your domain and hosting, build a simple and clean website that explains who you are, what you offer, and how people can contact you. You don’t need to be a web expert; there are many platforms, such as WordPress, that make this easy for beginners.

Your brand also includes your:

• Logo.
• Colors.
• Tone of voice.

These should be the same across your website and social media. Additionally, setup social profiles on platforms where your customers spend time, like Facebook, Instagram, LinkedIn, or TikTok. This helps people find you and trust you.

Step 14: Marketing & Branding Your Business

Marketing helps people discover your business, trust your brand, and become loyal customers. It starts with building your brand. Whether you’re posting online or printing flyers, everything should look and sound consistent, so your business is easily recognizable.

Next, setup a professional website. Even a simple one with a few clear pages can make a huge impact. Share who you are, what you offer, and how customers can contact or buy from you. Use clear calls to action, such as Shop Now or Get a Free Quote, to guide visitors.

Then, create a marketing plan that fits your goals and budget. This plan should explain where and how often you’ll promote your business, and the type of content or messages you will use.

Pick the best channels based on where your audience spends their time. This could be:

• Social media.
• Email newsletters.
• Search ads.

Social media is one of the simplest, most cost-effective ways to reach people. Post helpful tips, behind-the-scenes content, or updates about your products or services. For local exposure, use community outreach; join local events, leave flyers at shops, or collaborate with other small businesses.

Don’t forget about Search Engine Optimization, which helps your site appear when people search on Google. Use keywords your customers are likely to type, and ensure your site loads quickly and works well on mobile phones.

It’s also smart to have a SWOT analysis for your business to check its Strengths, Weaknesses, Opportunities, and Threats. It shows what you’re doing right and where you can improve. Combine this with market research to understand what your competitors are doing and what your target customers need.

When you’re ready to launch, create a buzz with a first-sale offer, such as a discount, freebie, or limited-time deal. It’s a great way to attract your first customers and start building momentum.

With the right strategy and tools in place, your marketing can help your business grow faster and reach the right people at the right time.

Step 15: Maintain Compliance

After your business is up and running, you’ll need to maintain its good standing with the state. That means staying on top of a few key tasks each year.

First, most California businesses need to file annual or biennial statements with the Secretary of State (SOS). These updates include your business address, ownership details, and registered agent info. You’ll get a reminder when it’s due, but it’s smart to mark your calendar just in case.

Next, keep track of your license and permit renewal dates. Many local and state licenses aren’t one-time. You may need to renew every year or every few years, depending on your business type and location. Missing a renewal could lead to fines or business closure.

Also, ensure you’re following local zoning laws. Zoning rules decide where certain businesses can operate. If you change locations, add services, or work from home, check with your city or county to ensure you are compliant.
