Does the California Secretary of State allow series LLCs?

Only if California's LLC act authorizes them, which not all states do. Where California allows it, you file one certificate that lets the LLC create protected series inside it; where it does not, you form in a series-friendly state and register in California as a foreign LLC. We confirm California's exact status before you build on a series structure.

How do I file a series LLC with California?

In a series state, you file a certificate of formation with the specific series language California requires, then document each series internally under the master Operating Agreement rather than filing each with the SOS. We prepare the correct California series certificate and the master agreement that makes the shield real.

How is a California series LLC taxed?

Federal treatment is still developing; many owners file per series while others report under the parent, and California may follow federal or apply its own rule. We flag the current California and IRS treatment and obtain each series its EIN where its activity requires one.

Is a series LLC cheaper than multiple LLCs in California?

Usually: you pay one California formation fee for the parent rather than a fee per series, though some states add a per-series charge, and the bigger cost is disciplined record-keeping. Current California figures and our service pricing are on the pricing page.

Can I convert my regular California LLC to a series LLC?

Often yes where California allows series, by amending the certificate and Operating Agreement to authorize series. It is not automatic; opening sub-accounts does not create a series. We handle the California amendment and rebuild the agreement so the shield is actually in place.

Is a series LLC the same as a holding company?

No: a holding structure owns separate subsidiary LLCs each with its own filing, while a series LLC keeps them inside one entity as series. The holding route is more widely respected across states; the series LLC is cheaper. We help you weigh which fits California and where you operate.

Can File.Business form a California series LLC?

Yes. We confirm California authorizes series, file the correct certificate with the required series language, build the master Operating Agreement, and set up EINs and records per series, so the structure is legally real rather than just sub-accounts under one name.

California does not authorize Series LLCs. Here is what to do instead.

California has not statutorily authorized the Series LLC structure. Founders looking for the asset-segregation benefits of a Series LLC have three practical alternatives: standalone LLCs per asset, parent-subsidiary structure, or a Series LLC formed in a state that authorizes them (typically Delaware, Texas, Illinois, or Nevada) with foreign qualification into California.

Three alternatives for California founders

1. Standalone LLCs per asset

Form a separate California LLC for each property or risk pool. Cleanest structure, full asset protection, but higher cost per entity.

2. Parent-subsidiary structure

A holding LLC owns multiple operating subsidiaries. Each subsidiary owns one asset or business line. Common for real estate and multi-brand operations.

3. Series LLC in Delaware + foreign qualification

Form the Series LLC in a state that authorizes them (Delaware, Texas, Illinois, Nevada), then foreign-qualify in California. Inter-series protection works in the home state; respect by California courts is uncertain.
