S Corporation Restrictions

S corps have several restrictions, such as being limited to one class of stock and a maximum of 100 shareholders. Read our What Is an S Corporation guide for full details.

Are S Corp Tax Advantages Right for You?

An S corporation is a tax designation that can be elected by an LLC or corporation. With an S corp, business owners are considered employees of the company and must receive a reasonable salary. Since all S corps technically have employees, the s corp must run payroll. 

In order to benefit from a California S corp tax designation, your business needs to make enough money to offset payroll expenses. Furthermore, S corps are beneficial for business owners who take large distributions in addition to their salary.

How to Form a California S Corp

If you’re considering forming an S corp, you should know that an S corporation is a tax classification under Subchapter S of the Internal Revenue Service (IRS). S corp business owners elect this tax status for either an LLC or a corporation, since it provides tax benefits. You can form your California S corp by completing and filing Form 2553 with the IRS. In California, an S corp has a franchise tax of 1.5%.

Corporations with a C Corp IRS tax classification have double taxation (business is taxed and shareholders are taxed again on business distributions) and LLCs have pass-through taxation (all profits, credits, distributions, deductions, and losses pass directly to the owner). An S corp requires business owner(s) to have a reasonable salary based on their position and the appropriate market compensation to qualify for this type of tax classification, which results in more IRS scrutiny. Sole proprietorships and partnerships do not qualify for S corp tax status since they are informal business structures.

The following are some S corp tax advantages:

  • S corps are not taxed at the business level (as opposed to C corps). S corps pass through earnings, losses, and deductions to the owner(s). However, California S corps pay a 1.5% franchise tax or an $800 minimun. 
  • Business owner(s) pay employment taxes and income tax on their salary
  • Distributions, which are net profits (profits after operational costs, deductions, credits, income), only pay income tax on each individual owner’s income tax return within their respective tax bracket. This is where the tax savings occur since there is no employment tax paid on this portion!

S corps are required to have no more than 100 shareholders who are U.S. citizens or permanent resident aliens, among other restrictions. 

There are Two Main Ways to Form an S Corp:

  • By forming an LLC and electing S corp tax status from the IRS when you request your employee identification number (EIN)
  • By forming a corporation and electing S corp status from the IRS

We recommend forming an LLC because it’s simpler and more cost-effective.

Steps to Form an LLC and Elect S Corp Tax Status in California

Starting a California LLC and electing S corp tax status is easy. You can use our guides to start an LLC with the S corp status yourself, or you can hire a service provider like Northwest to guide you through this process.

There are six basic steps to start an LLC and elect S corp status:

Step 1: Name Your LLC

Step 2: Choose a Registered Agent

Step 3: File the Articles of Organization

Step 4: File Initial Statement of Information

Step 5: Create an Operating Agreement

Step 6: Get an EIN and File Form 2553 to Elect S Corp Tax Status

Step 1: Name Your LLC

Choosing a company name is the first and most important step in starting your LLC in California.

Be sure to choose a name that complies with California naming requirements and is easily searchable by potential clients.

1. Follow the naming guidelines for a California LLC:

  • Your name must include the phrase “limited liability company,” or one of its abbreviations (LLC or L.L.C.)
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • The name cannot include the following words: bank, trust, trustee, incorporated, inc., corporation, or corp.
  • The name cannot include the words “insurer” or “insurance company” or any words suggesting that it is in the business of issuing policies of insurance and assuming insurance risks.
  • The name must be distinguishable from any other LLC registered with the Secretary of State. You can read more about what makes a name distinguishable on the California Secretary of State website.

You can also read the California state statute about LLC naming guidelines for more information.

2. Is the name available in California? You can use the business entity search on the California Secretary of State website to see if your desired LLC name is available.

3. Is the URL available? We recommend checking to see if your business name is available as a web domain. Even if you don't plan to create a business website today, you may want to buy the URL in order to prevent others from acquiring it.

Step 2: Choose Your California Registered Agent

You must elect an agent for service of process, also known as a registered agent, for your California LLC.

An LLC registered agent will accept legal documents and tax notices on your LLC's behalf. You will list your registered agent when you file your LLC's Articles of Organization.

Many business owners choose to hire a registered agent service. Many of these services will form your LLC for a small fee and include the first year of registered agent services for free.

Step 3: File the California LLC Articles of Organization

The California LLC Articles of Organization is used to officially register an LLC.

Keep Your California S Corp Compliant

After you successfully form your business and elect the S corp tax designation for it, you must follow state laws to ensure your business remains compliant and can continue to operate in good standing. All California S corps need to file a Statement of Information every two years and a Form 100S each year.

California Statement of Information

Your California S corp must file a Statement of Information with the California Secretary of State every other year. If you registered your business in an odd year, for example, you’ll file this report during every following odd year. The filing deadline is based on your business’s original registration date. 

Visit our California Statement of Information guide for more information. 

California S Corp Taxes

S corporations benefit from pass-through taxation, meaning the business’s profits pass-through to S corp owners’ individual tax returns. S corp owners make money from their reasonable salary and distributions, and California S corp owners can expect to pay the following taxes:

Federal Self-Employment Taxes

Self-employment taxes cover social security and medicare. The self-employment tax rate is 15.3%, and money you take as salary will be subjected to the self-employment tax. However, distributions are not subjected to this tax.

Federal Income Taxes

Your federal income taxes will depend on your tax bracket, and the cutoffs for individual tax brackets as well as the percent owed will change each year. Both your salary and distributions are subjected to federal income tax.

California Franchise Tax

All S corps within the state must file Form 100S each year and pay California’s franchise tax. The California franchise tax rate is 1.5% on net income, and the minimum franchise tax rate is $800 by default. That means your S corp will need to pay at least $800 each year even if it’s inactive or loses money. 

Form 100S is due by March 15 each year, and you should file it with the California Secretary of State. As an S corp owner, you’re responsible for paying the California franchise tax in addition to state income taxes.

California Income Taxes

California has some of the highest income tax rates in the country. Similar to federal income taxes, the California state income tax rate varies based on your yearly income and if you file as an individual or with your spouse. While the lowest rates start at 1%, the highest tax rates can exceed 10%. 

Because a 10% state income tax rate is significantly higher than that of other states, you should keep this in mind when deciding if California is the best place for you to do business.

California Sales and Use Tax

California’s statewide sales tax rate is 7.25%. California retailers must register with the California Department of Tax and Fee Administration to ensure they pay taxes on the goods they sell. While 7.25% is the statewide sales tax rate, many cities have their own sales tax that businesses must pay in addition to the statewide sales tax.

California Local Taxes

Check with your local municipality to ensure your business complies with local laws. Whether your business operates in Los Angeles, San Francisco, or a smaller city in the state, each local municipality may have its own taxes that apply to your business.

Start a California S Corp FAQ

An S corporation (S corp) is a tax designation that an LLC or a corporation can elect.

No. The default taxes for an LLC and taxes for an S corp are not the same.

With an S corp, owners pay personal income tax and self-employment tax on a predetermined salary. They may then withdraw any remaining profits from the business as a “distribution,” which isn’t subject to self-employment tax.

With an LLC, all company profits pass through to the owners’ personal tax returns, and then the owners must pay personal income tax and self-employment tax on the entire amount.

S corp owners are required to earn a “reasonable” salary, which basically means a fair market rate based on the individual’s qualifications as well as their duties and responsibilities at the company. The purpose of this requirement is to prevent S corp owners from paying themselves an artificially low salary in order to pay less self-employment tax.

A distribution is a dividend that a shareholder/owner can take from the business profits that remain after a company pays all of its employee salaries. Shareholders must pay personal income tax on distributions, but distributions aren’t subject to self-employment tax.

LLCs and corporations that operate under a “doing business as” (DBA) name can choose the S corp election.

Unlike most states, California requires businesses to file a report — called a Statement of Information — every two years. While this report may not be called an annual report, it contains the same information.

The state of California requires business entities to pay a franchise tax. This tax will either be $800 or 1.5% of your business’s annual income (whichever is greater). You must file Form 100S each year in order to account for and pay this tax.
