Step-by-step guidancePrimary sourcesPlain-English methods

What should you decide before opening a business?

Imagine you are opening a Sacramento bakery. You have the lease address, but the city business licence application asks for zoning clearance and entity details.

Entering the wrong information can delay the application. Before continuing, define the activity, address, owners, and sales model.

Your next decision is whether the bakery will operate as a sole proprietorship, partnership, corporation, or limited liability company (LLC).

A legal name identifies the person or registered entity that owns the business. A brand name is the name used in marketing.

A fictitious business name, commonly called a doing business as (DBA) name, may require county registration. The requirement depends on whether the business operates under a name different from the owner’s or entity’s legal name.

Once those details are clear, examine the California requirements.

What does California require?

California requires separate checks for entity formation, tax registration, business licensing, professional licensing, seller’s permits, and local permits. Entity formation creates an LLC or corporation.

It does not register the business for tax accounts, issue a professional licence, provide a seller’s permit, or approve a local business licence.

Example: a Sacramento bakery

For the bakery example, selling taxable goods changes the registration path, while food preparation and the Sacramento address can trigger local requirements. The operator should check zoning and business-licence requirements with the City of Sacramento Community Development Department and food-related requirements with Sacramento County Environmental Management.

A freelance consultant working from home may follow a different business California permit path because the activity and city differ. The California Governor’s Office of Business and Economic Development (GO-Biz) explains that required approvals depend on the business type and activity (GO-Biz permit assistance).

Next, identify which agencies own each action.

Which state registrations come first?

The registration sequence begins with the entity decision and continues through revenue, employer, and permit checks. Follow this business order:

  1. Choose the ownership structure.
  2. Check the proposed entity designation.
  3. File formation documents when forming an LLC or corporation.
  4. Obtain an employer identification number (EIN), the federal tax identifier issued by the Internal Revenue Service.
  5. Review California tax and employer registrations with the agencies responsible for those accounts.
  6. Check city, county, professional, and activity-specific approvals.

A sole proprietorship or general partnership does not follow the same formation path as a corporation, LLC, limited partnership, or limited liability partnership (LLP). The relevant California Codes and professional rules can also affect whether a particular entity type is available for the activity.

That distinction leads to the LLC decision.

Is an LLC the right structure?

An LLC separates the entity from its owners, but it does not automatically provide the best tax or operational result for every business. Compare liability, ownership, taxation, financing plans, and recurring administration before choosing it over a sole proprietorship, partnership, or corporation.

A California LLC generally forms by submitting Articles of Organization to the California Secretary of State. A corporation instead uses Articles of Incorporation.

These formation documents do not replace an EIN, seller’s permit, local business licence, or professional licence. An owner who is uncertain about liability or tax treatment should obtain qualified legal or accounting advice before filing with the state.

What does the Secretary handle?

The California Secretary of State handles entity records and formation filings, not every approval needed to operate a business. Its bizfile Online portal provides access to business searches and filing services.

Secretary state records can help confirm whether an LLC or corporation appears in the database. They do not establish federal trademark rights or prove that a city has approved the location.

The California Secretary of State is therefore one stop in a longer business California sequence.

How do Secretary of State records differ from local records?

California Secretary of State records document entity matters, while local records document requirements assigned to a city or county. A business can appear in California secretary state search results and still need zoning clearance, a city business licence, a county fictitious business name filing, or an activity-specific local permit.

For the Sacramento bakery, the LLC record and Articles of Organization belong in the formation file. The lease address, zoning clearance, city business licence, and food-related approvals belong in the local business records.

By contrast, a home-based consultant in another city would check that city’s business-licence and home-occupation rules rather than Sacramento’s requirements. An entity search should confirm registration, not create an assumption that every licence is complete.

What should you verify when starting operations?

When starting operations, verify that each registration matches the business activity, address, legal name, fictitious business name, entity details, and employer status. Keep formation records, the EIN letter, tax registrations, permit decisions, and renewal notices together.

Separate one-time filing fees from recurring state obligations, local charges, and optional service fees. The path can change when the business hires workers, adds a location, changes ownership, adopts a new DBA, or begins selling different goods.

Current information should come from the agency responsible for the specific action: the California Secretary of State for entity filings, the relevant tax or employment agency for registration, the licensing board for a regulated profession, and the named city or county office for local approvals.

What is the final entity check?

The final entity check is to confirm the correct legal name and entity record, then verify every non-formation obligation with its owning agency. Review the business entry and available filings through bizfile Online, then use California GO-Biz to identify the relevant local, state, and federal permit contacts.

Formation is complete only for the entity; operating authority depends on the business activity and address.

Check the California Secretary of State for entity filings, California GO-Biz for permit and regulatory assistance, and the city or county agency responsible for the business address before opening.
