# Series LLCs and California

> California won't let you form a series LLC, and the FTB taxes each series as its own LLC. What that costs, the liability risk, and better options for owners.

**Short answer:** You can’t form a series LLC in California. You can form one in a state like Delaware or Texas and register it here, but the Franchise Tax Board treats each series as its own LLC, so each one pays the annual tax and files its own return. The tax savings disappear, and the liability wall between series is untested in California. For most California owners, separate LLCs or a holding company do the job with more certainty.

- The FTB states that a series LLC “cannot be formed in California” and that one formed elsewhere must register with the Secretary of State before doing business here (FTB, Series LLC).
- Each series is a separate LLC for California tax, filing its own Form 568 and paying its own annual tax and fee if it’s registered or doing business here (FTB Form 568 Booklet).
- A foreign LLC’s internal affairs and its members’ liability are governed by the law of the state where it was formed (Corp. Code § 17708.01(a)).
- The annual tax applies to LLCs formed under the law of any state (Rev. & Tax. Code § 17941(d)).

Series LLCs get pitched to California real estate investors as a way to put each rental in its own compartment for the price of one LLC. The first half of that pitch describes how a series LLC works in Delaware. The second half fails at the Franchise Tax Board.

## What is a series LLC?

A series LLC is one LLC divided into internal compartments, called series or cells, each with its own assets, members, and debts. In states that authorize them, a creditor of one series can collect only from that series’ assets, as long as the records and formalities are kept.

The FTB describes it as a group of LLCs owned in a tiered structure, where the top-tier LLC owns the lower-tier LLCs, and “each unit has its own owners (members) and is liable only for its own debts and obligations.” Delaware’s version is typical. Its statute protects a series only if the LLC agreement provides for it, the records account for each series’ assets separately, and the certificate of formation gives notice of the limitation (Delaware Code, Title 6, section 18-215(b)). California’s LLC act is the California Revised Uniform Limited Liability Company Act (Corp. Code § 17701.01). It has no series provisions at all.

## Can you form a series LLC in California?

No. The FTB’s own page says “A SLLC cannot be formed in California.” The California Secretary of State has no articles form for a series LLC, and nothing in the Corporations Code authorizes one.

What you can do is form a series LLC in another state and register it here as a foreign LLC. A foreign LLC that transacts intrastate business in California applies for a certificate of registration with the Secretary of State ([Corp. Code § 17708.02](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CORP&sectionNum=17708.02)), and the FTB says a series LLC formed elsewhere “must register” before it starts doing business in California.

## How does California tax a series LLC?

As if every series were a separate LLC. That’s the part that erases the cost savings.

The FTB’s Form 568 instructions say that if the home state’s law limits each series’ holders to that series’ assets and limits each series’ liabilities to its own assets, “then each series in a series LLC is considered a separate LLC and must file its own Form 568 and pay its own separate LLC annual tax and fee, if it is registered or doing business in California.” The FTB’s series LLC page repeats the filing list for each series. Each one pays the $800 annual tax by the 15th day of the 4th month of the tax year, estimates and pays the LLC fee by the 15th day of the 6th month, and files Form 568.

The FTB also has a numbering procedure for series. The first series uses the Secretary of State file number on its first payment voucher, the others leave it blank, and the FTB assigns each remaining series its own number after it receives the first voucher. That procedure exists because the FTB expects a separate account for every series.

The annual tax itself reaches LLCs formed under the law of “this state, any other country, or any other state” ([Rev. & Tax. Code § 17941(d)](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=RTC&sectionNum=17941)). Forming in Delaware doesn’t take a California business outside it. See my guide to [the $800 LLC tax](https://ridleylawoffices.com/california-llc-800-tax/) for the current first-year rules.

### A worked example

An investor in Oxnard owns four rental houses and wants each walled off from the others. The table compares the California cost of the structures he’s considering.

| Structure | California annual tax | California returns | Other costs |
| --- | --- | --- | --- |
| Four California LLCs | $3,200 (4 x $800) | Four Form 568s | Four Statements of Information |
| Delaware series LLC with four series, registered in California | $3,200 (4 x $800) | Four Form 568s | Delaware charges and registered agent, a California foreign registration, and an untested liability wall |
| California holding LLC owning four California LLCs | $4,000 (5 x $800) | Five Form 568s | One assignment to the living trust covers all five |

The series LLC saves nothing on California tax and adds another state’s fees. If the rents in any one series reach $250,000 in total income, that series also owes the LLC fee under [Rev. & Tax. Code § 17942](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=RTC&sectionNum=17942), the same as a stand-alone LLC would.

## Will a California court respect the wall between series?

Nobody can promise that. It’s the biggest reason I rarely recommend a series LLC to a California owner.

California’s foreign LLC statute says the law of the formation state governs a foreign LLC’s organization, internal affairs, and “the liability of a member as member and a manager as manager” for the LLC’s debts ([Corp. Code § 17708.01(a)](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CORP&sectionNum=17708.01)). That’s a rule about owners’ liability. It doesn’t say whether a California court will stop a tenant injured at a house in Series A from collecting against the house in Series B, which is a question about the LLC’s own assets.

I haven’t found a California statute that answers that question. If the house in Series A is in Oxnard, the injured tenant sues in Ventura County Superior Court, and the investor is asking a California judge to apply a Delaware concept California’s own law doesn’t recognize. Separate LLCs don’t have that problem, because each one is a separate entity under any state’s law (Corp. Code § 17701.04(a)).

The practical risks point the same way. The series has to keep separate records for each cell, and a series LLC that mixes rents or pays one property’s repairs from another’s account invites the argument that the wall was never real. Title companies and lenders also tend to want a stand-alone borrower, so ask yours before you plan around a series.

## Is a series LLC ever worth it for a California owner?

Occasionally, when most of the activity is outside California. An investor who lives in California but owns rentals only in Texas might use a Texas series LLC for those properties, because the California tax question turns on whether each series is registered or doing business here. That analysis belongs with your CPA, and it depends on facts like where the LLC is managed, since an entity commercially domiciled in California is doing business here ([Rev. & Tax. Code § 23101(b)(1)](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=RTC&sectionNum=23101)).

For California property and California businesses, the alternatives are simpler:

- **Separate California LLCs.** Same tax as a series, clearer liability law, and no second state. Each one needs its own bank account and books.
- **A holding company.** A parent LLC owns the separate LLCs and is their manager, so one entity signs for all of them and one trust assignment covers the group. My [holding company LLC guide](https://ridleylawoffices.com/holding-company-llc-california/) walks through the setup and the property tax traps.
- **One LLC plus insurance.** For a couple of rentals with modest equity, good liability coverage and an umbrella policy often matter more than a second entity. My [rental LLC guide](https://ridleylawoffices.com/guides/rental-llc/) covers when an LLC pays for itself.

## What if I already have a series LLC holding California property?

Start with registration. Confirm the LLC is registered with the California Secretary of State, since a foreign LLC transacting intrastate business here without registration can’t maintain a lawsuit in a California court (Corp. Code § 17708.07(a)). Next, confirm each series has its own FTB account, pays its own annual tax, and files its own Form 568, because the FTB’s instructions require it. Then look at the records and bank accounts series by series, because the liability wall is only as strong as the separation.

If the structure isn’t doing anything a set of California LLCs wouldn’t do better, we can plan a move out of it. Moving California real estate between entities raises reassessment and transfer questions, so plan the deeds before anyone signs one. The reassessment rules are in my [holding company guide](https://ridleylawoffices.com/holding-company-llc-california/), and the [annual requirements page](https://ridleylawoffices.com/california-llc-annual-requirements/) lists what each entity files.

## How does a series LLC fit into an estate plan?

The same way any LLC does. The membership interest should be owned by your living trust, or it goes through probate when you die. With a series LLC, check that the assignment covers the interests in each series as well as the master LLC, since the series may have their own members. My guide on [what happens to an LLC when the owner dies](https://ridleylawoffices.com/llc-owner-dies-california/) explains why the assignment matters.

## Frequently asked questions

### Does California recognize series LLCs?

For tax, yes, by treating each series as a separate LLC. For formation, no, since you can’t form one here. For liability, California’s statutes don’t say whether a court will honor the wall between series, so that protection is untested.

### Does each series pay the $800 franchise tax?

Yes, if the series is registered or doing business in California. The FTB’s Form 568 instructions say each series “must file its own Form 568 and pay its own separate LLC annual tax and fee.” Four series means four annual taxes.

### Can I form a Delaware series LLC and use it for California rentals?

You can, but you’ll register it here, pay California’s annual tax for every series, and pay Delaware’s charges too. You’ll also be relying on a liability wall California’s own statutes don’t address. Separate California LLCs cost the same in California tax and avoid that question.

### Is a series LLC cheaper than multiple LLCs in California?

Not in California tax. The FTB charges each series the same annual tax and fee a separate LLC would pay. You may save a little on formation paperwork, which the second state’s fees usually eat.

### What’s the difference between a series LLC and a holding company?

A series LLC is one entity with internal compartments. A holding company is a parent LLC that owns separate LLCs, each a full entity under California law. The holding structure costs one more annual tax but rests on settled law.

### Will California ever authorize series LLCs?

It hasn’t as of September 2026, and nothing in the Corporations Code provides for them. If the Legislature changes that, the FTB’s position that each series is a separate taxpayer would still matter for the cost comparison.
