Washington LLC Questions, Answered

What document creates an LLC in Washington?

Washington uses the Certificate of Formation — the state's term for what many other states call Articles of Organization. You file it with the Secretary of State's Corporations & Charities Division through the online CCFS system at ccfs.sos.wa.gov. It lists your LLC name, registered agent, and principal office.

How long does formation take?

Online filings generally process in a few business days. Paper filings by mail take much longer — often several weeks. If you have a deadline, file online and, if necessary, use the Secretary of State's expedited service. Your LLC is active and usable once the state processes the filing and it appears in CCFS.

Do I have to live in Washington to form a Washington LLC?

No. There is no residency requirement for members or managers. Anyone can own a Washington LLC. The sole thing that has to be based in the state is your registered agent, who needs a physical Washington street address. A commercial registered agent service satisfies that for out-of-state owners.

Can one person form an LLC?

Yes. Washington allows single-member LLCs. A single-member LLC still gets the liability shield and is taxed by default as a disregarded entity for federal purposes, meaning you report income on your personal return.

What is a UBI number?

A Unified Business Identifier (UBI) is a nine-digit number Washington assigns to your business. The same UBI is used by the Secretary of State, the Department of Revenue, and the Employment Security Department, so it ties your various state accounts together. You will use it when you apply for your state business license.

What is the Initial Report?

Washington requires a new LLC to file an Initial Report with the Secretary of State within 120 days of formation. It confirms your registered agent and governing-person information. Most people file it at the same time as the Certificate of Formation, which avoids a separate deadline and an extra charge for filing it on its own.

What is the Annual Report?

After formation, every Washington LLC files an Annual Report with the Secretary of State each year, due by the end of the anniversary month of formation. It keeps your registered agent, principal office, and governing-person details current. It is not a financial disclosure. Letting it lapse leads to loss of good standing and, eventually, administrative dissolution.

Do I need a registered agent?

Yes, always. Every Washington LLC must have a registered agent with a physical Washington street address who consents to serve. The agent receives lawsuits and official state notices during business hours.

Can I be my own registered agent?

Yes, if you have a Washington street address and are available during business hours. The catch is that your address becomes part of the public CCFS record. Many owners use a commercial service to keep a home address private and delivery reliable.

Can I use a P.O. box?

No. The registered office must be a physical Washington street address where documents can be delivered in person. A P.O. box alone does not qualify.

Does the agent have to agree?

Yes. Washington requires the registered agent to consent to the appointment. You cannot name someone without their agreement. Commercial services provide that consent as part of signing up.

Does Washington have a state income tax?

No — Washington has no personal or corporate income tax. Instead, most businesses pay Business & Occupation (B&O) tax, a gross-receipts tax collected by the Department of Revenue. B&O tax applies to revenue regardless of profit, and the rate depends on your business classification. Sales tax may also apply depending on what you sell.

Do I need a state business license?

Most Washington businesses do. It is issued through the Department of Revenue's Business Licensing Service, separately from your Secretary of State filing. This is where you register for B&O tax and any city endorsements. Your UBI number links the license to your LLC.

How is a Washington LLC taxed federally?

By default, a single-member LLC is a disregarded entity (Schedule C on your personal return) and a multi-member LLC is a partnership (Form 1065). You can elect S-corporation or C-corporation treatment with the IRS if the numbers justify it. Talk to a CPA before making that election.

Do I need an EIN?

You need one if your LLC has more than one member, hires employees, or elects corporate tax treatment — and most banks require an EIN to open a business account. It is free from the IRS and issued immediately when you apply online at IRS.gov. Even single-member LLCs usually get one to keep the owner's SSN off business paperwork.

How do I know if my name is available?

Search the CCFS system. Your LLC name must include a designator like "LLC" and be distinguishable from other names already on the Corporations Division's records. Minor differences in punctuation or filler words generally are not enough to make two names distinguishable.

Can I change my LLC's name later?

Yes. You file an amendment to the Certificate of Formation with the Secretary of State to change the official name. If you simply want to operate under a different brand, you can register a trade name (DBA) through the Department of Revenue instead.

What if I need to change my registered agent?

File the change through CCFS, entering the new agent's name and Washington address along with their consent. Keep the old agent in place until the update is confirmed, so there is never a gap.

How do I close a Washington LLC?

You wind up the business, settle debts and obligations, and file a Certificate of Dissolution (and related cancellation paperwork) with the Secretary of State. You also close out your Department of Revenue accounts, including final B&O tax filings. Formally dissolving stops future Annual Report obligations and prevents the entity from lingering with unmet requirements.
