A California contracting company may need several registrations, not one all-purpose filing. The right order is to choose the business structure, form or register the entity when required, obtain the tax accounts that apply, qualify for the correct CSLB classification, and check state and local permits for the actual work location.
1. Choose the business structure
The California Secretary of State describes corporations and limited liability companies as entities formed by filing with the state. A sole proprietorship does not file a formation document with the Secretary of State, although a fictitious business name may need to be filed with the county when the owner operates under another name.
Review the Secretary of State's official entity-type guidance. Entity choice affects ownership, liability, taxes, filings, and how a future CSLB license is issued. An LLC also faces extra CSLB requirements discussed below.
2. Form or register the entity
The Secretary of State routes online entity filings and business searches through bizfile Online. A California LLC is formed by filing Articles of Organization. Its operating agreement is required by the state's entity guidance but is maintained internally rather than filed with the Secretary of State.
After formation, keep the entity's public record current. The Secretary of State warns that failing to file required Statements of Information can lead to penalties and suspension or forfeiture. Use the agency's current filing-period page for the entity-specific schedule.
3. Set up the applicable tax accounts
The Secretary of State's startup sequence places federal and state tax identification after entity selection and formation. The accounts depend on how the company operates. For example, CDTFA says a seller's permit is required when a business is engaged in business in California and sells or leases taxable tangible personal property at retail. Do not treat an entity number, federal EIN, seller's permit, payroll account, and CSLB license number as interchangeable.
4. Determine whether the work requires a CSLB license
CSLB's current applicant guidance says a contractor license is required when a project requires a building permit, uses additional workers, or has a combined labor-and-material value of $1,000 or more. A project cannot be split into smaller contracts to evade that threshold.
Each license needs a qualifying individual for the requested classification. CSLB generally requires four years of journey-level or higher experience within the previous ten years and examinations unless an identified waiver applies. Match the intended work to CSLB's classification directory before applying.
5. File the bond and entity-specific insurance
CSLB states that the standard contractor bond is $25,000 and must use the exact business name and license number on the CSLB record. A qualifying individual may need a separate $25,000 bond depending on the qualifier's role and ownership. Review the official bond requirements rather than relying on a quote alone.
6. Check state and local permits
Contractor licensing does not replace every operational permit. The Governor's Office of Business and Economic Development provides permit and regulatory assistance and directs businesses to CalGOLD for federal, state, and local permit information. Verify the city, county, job type, and regulated trade before opening or bidding.

Frequently asked questions
Can the LLC start work as soon as it is formed?
No. Entity formation creates the company. It does not activate a CSLB contractor license.
Is every small job exempt?
No. The under-$1,000 exemption also requires that the work need no permit and use no employees, and other regulated-work rules can still apply.
Is a California business permit the same as a contractor license?
No. Local business permits, tax registrations, professional or trade permits, and the CSLB contractor license are different layers.
