Series LLC in Oregon — Not Available (Alternatives Explained)

Oregon does not authorize Series LLCs under ORS Chapter 63. If you need liability isolation between multiple business activities, you must use alternative structures available under Oregon law. This page explains what Series LLCs are, why Oregon doesn't offer them, and what Oregon LLC owners can do instead. For formation, see our LLC formation guide. For all types, see our LLC types overview.

What Is a Series LLC?

A Series LLC (available in about 20 states including Delaware, Illinois, Texas, Nevada, and Wyoming) is a single LLC containing multiple internal "series." Each series can:

• Own separate assets
• Have separate liabilities isolated from other series
• Have different members or managers
• Conduct different business activities
• Maintain separate books and records

Primary use case: Real estate investors who want one LLC per property without forming and maintaining a separate entity for each.

Why Oregon Doesn't Offer Them

Oregon has not adopted Series LLC legislation. The Oregon legislature has not enacted any version of the Uniform Protected Series Act or created its own Series LLC statute. Reasons often cited:

• Uncertain liability protection — Limited case law on whether series liability shields hold up in court
• Tax complexity — The IRS has not issued final regulations on Series LLC taxation
• Interstate recognition — If you form a Series LLC in another state and operate in Oregon, Oregon courts may not respect the internal liability shields
• Creditor confusion — Difficulties for creditors and courts in determining which assets belong to which series

Alternatives for Oregon LLC Owners

Option 1: Multiple Standard Oregon LLCs

Best for: Real estate investors, multi-brand businesses, ventures with distinct liability profiles

• Form a separate Oregon LLC for each property or business activity
• Each LLC: $100 formation + $100/year Annual Report
• Clear, well-tested liability isolation between entities
• Separate EINs, bank accounts, and records for each
• No ambiguity about asset ownership or liability allocation

Cost comparison (5 properties):

• Series LLC (if available): $100 formation + $100/year Annual Report = $200 total first year
• Multiple LLCs: 5 x ($100 formation + $100/year) = $1,000 first year, $500/year ongoing
• More expensive, but legally clearer and tested in Oregon courts

Option 2: Holding Company Structure

Best for: Complex businesses wanting centralized management with entity-level liability isolation

• Form a parent Oregon LLC
• Form subsidiary Oregon LLCs (one per asset or activity)
• The parent LLC owns 100% of each subsidiary
• Management flows from parent down
• Each subsidiary's liabilities are isolated from the parent and siblings

Option 3: Series LLC Formed in Another State (Caution)

Technically possible but risky:

• Form a Series LLC in Delaware, Illinois, Nevada, or Wyoming
• Register the parent entity as a foreign LLC in Oregon ($100)
• Operate in Oregon through the series

Risks:

• Oregon courts have no obligation to recognize series liability shields
• No Oregon case law confirming protection
• A creditor in Oregon might argue that the series structure isn't valid under Oregon law
• Each series operating in Oregon might independently require foreign registration ($100 each)
• You maintain compliance in two states

This approach should only be considered with attorney guidance specific to your situation. It is not recommended for most small businesses.

Real Estate Investors in Oregon

The most common reason people seek Series LLCs is for real estate. Oregon real estate investors typically:

1. Form one LLC per property — cleanest liability isolation
2. Use a management LLC — one LLC manages all properties (earns management fees), separate LLCs own each property
3. Accept the higher cost — multiple $100/year Annual Reports is the price of clear protection in Oregon

Land trust alternative: Some Oregon investors use Oregon land trusts (revocable trusts that hold title to property) combined with an LLC as beneficiary. This provides privacy (trust doesn't show owner name on public records) while the LLC provides liability protection.

FAQ

Will Oregon ever allow Series LLCs?

No current legislation is pending. The Uniform Law Commission published the Uniform Protected Series Act in 2017, but Oregon has not adopted it. There's no public timeline for potential adoption.

If I form a Series LLC in Delaware, is it valid in Oregon?

Oregon may not recognize the internal liability shields between series. Oregon courts apply Oregon law to LLC liability questions involving Oregon operations. Without Oregon Series LLC legislation, there's no statutory basis for courts to respect the series separations. This is an unresolved legal question.

Is forming multiple LLCs really that expensive in Oregon?

It's more expensive than a single LLC, but Oregon's costs are reasonable: $100 per entity per year. Five LLCs = $500/year in Annual Reports. Compare this to California where five LLCs = $4,000/year in franchise taxes alone ($800 per entity). Oregon's flat $100 Annual Report makes the multi-LLC strategy much more accessible.

Can I consolidate multiple Oregon LLCs later?

Yes. You can merge Oregon LLCs under the Oregon LLC Act (ORS Chapter 63) et seq. This combines two or more LLCs into one surviving entity. Useful if you determine you over-structured and want to simplify.
