If you’re currently self-employed in the state of California, or if you’re looking to enter the world of one-person business ownership, you’ve probably looked into becoming a sole proprietor.

The sole proprietorship is the simplest business ‘format’ in America, but that doesn’t mean that there aren’t rules and regulations to follow when you operate one. In addition, there are some limits to the functionality of a sole proprietorship.

In this guide, we’ll walk you through the steps to setup a sole proprietorship properly, and help you determine whether or not a sole proprietorship is a good choice for your business.

How to Become a California Sole Proprietor

When it comes to being a sole proprietor in the state of California, there is no formal setup process. There are also no fees involved with forming or maintaining this business type. If you want to operate a California sole proprietorship, all you need to do is start working.

However, just because it’s so easy to get started doesn’t mean there aren’t some additional steps you should take along the way. While these parts of the process aren’t strictly required, many sole proprietors find that they are in their best interests.

DBA Acquisition

A doing business as (DBA) name is a crucial part of many sole proprietorships, as it enables you to use an assumed name for your business, rather than your own personal name. The advantages of acquiring a DBA start with image ― most customers feel that an assumed name is more professional and trustworthy than doing business with a company that uses its owner’s personal name instead.

That said, sole proprietors can sign up for a business bank account using their DBA name, which is another step that goes a long way toward making customers feel more comfortable doing business with you.

You should begin the process of acquiring a DBA in California by conducting a preliminary business search through the California Secretary of State to see whether your desired business name is available.

Once you have determined that your DBA is not already in use, you must then file a Fictitious Business Name Statement with the county where your business is located. If you intend to file in Los Angeles County, for instance, you can use this application. Then, to complete the process of claiming your DBA, you must publish a statement in a major county newspaper for four consecutive weeks.

Determine Taxation Requirements

Sole proprietors without employees usually don’t need to acquire a federal tax ID number (EIN), because as a one-person business, you can typically just use your own social security number for most things an EIN is used for. Still, if you would rather not use your SSN for privacy purposes, it would be a good idea to get an EIN regardless.

Beyond that, the nature of your business will determine which taxes apply to you as a sole proprietor.

If your sole proprietorship sells handmade goods, for example, then you will need to register to pay sales and use tax. To register for this tax and other industry-specific taxes, you can use the California Tax Service Center, which will automatically sign you up to pay any taxes that apply to your sole proprietorship.

Obtain Business Licenses and Permits

There isn’t a requirement in California for sole proprietors to acquire a general business license, but depending on the nature of your business you may need other licenses and/or permits to operate in a compliant fashion.

California has a myriad of permits and licenses that apply to businesses in particular industries, so you should use the state’s CalGold permit and license search to find if you must obtain any permits or licenses to legally conduct your business in California.

In addition, you should check to see if your business needs any licenses or permits on the local level.

All of California’s major cities – including Los Angeles, San Diego, San Jose, San Francisco, and Fresno – have their own requirements, so you should check with your local government to ensure that you are in compliance with all licensing and permitting standards.

What Is a California Sole Proprietor?

As opposed to a corporation or limited liability company (LLC), the sole proprietorship is not a legal business entity. The sole proprietorship is a one-person business that is not considered to be a distinct entity from the person who owns it, and it is frequently operated using the owner’s personal name.

Here are the three main things you need to know:

Tax Responsibilities

Because there’s no distinction between the owner and the business itself, sole proprietors don’t need to file business tax returns ― they instead simply claim any business profits or losses on their personal tax returns.


Sole proprietors are allowed to sign contracts using their personal name, and along those same lines, customers can write checks to the business by using the sole proprietor’s name.

More Flexible

The other big difference between sole proprietorships and more formal business structures is the fact that sole proprietors are allowed to commingle business and personal assets as much as they want to. With LLCs and corporations, ownership is required to keep their assets separate from those of the company. The downside of this aspect for sole proprietors is that if your business is sued, creditors are free to pursue your personal assets like your house, car, personal bank accounts, etc. For corporations and LLCs, creditors are limited to your business assets.


While the sole proprietor is such a simple business classification that California doesn’t even require a business registration process or any type of fees, depending on how you use your sole proprietorship and what industry you operate in, you still might have some important steps that need to be taken.

When it comes to issues of taxation, licenses and permits, or even the name you want to call your sole proprietorship, you do need to be vigilant to make sure you’re not overlooking anything.

We hope this guide helped you answer any questions you had for sole proprietorships in California, and we wish you success with your business!
