Starting a business in Washington is an exciting journey, and ZenBusiness is here to support every step. From initial ideas to launching your business, we provide the tools and guidance needed for success. This is your guide to limited liability companies (LLCs) in Washington. You’ll learn how our suite of products and services can assist you in forming, operating, and expanding your business from scratch.
Embarking on the journey of forming an LLC in Washington State involves several key steps to ensure your business is set up correctly and compliant with state regulations. From naming your LLC to obtaining vital tax identification, each step plays a crucial role in establishing the foundation of your business. Below, we outline the essential stages of this process, providing a clear roadmap for aspiring entrepreneurs to successfully launch their LLC in Washington.
This introduction provides a concise overview of the process, setting the context for the subsequent detailed steps.
Starting a limited liability company in Washington State isn’t as complicated as it may seem. It does, however, require meticulous attention to detail. Before you can officially submit your Certificate of Formation, there are initial factors you must consider. These include selecting a unique name that meets Washington’s requirements, appointing a registered agent to receive legal correspondence for your business, and developing an operating agreement as comprehensive as a business plan.
That might sound as daunting as crossing the Cascades in winter, but our abundant resources and support services can make the journey of forming an LLC in Washington more like a leisurely stroll along the Puget Sound. This will allow you to focus on what truly motivates you: constructing and growing your business, watching it rise and thrive.
Note: These directions apply to starting a domestic LLC in Washington. We’ll also cover the essentials of forming a professional LLC (PLLC), an LLC organized by licensed professionals like dentists, medical doctors, and lawyers. The formation steps and filing requirements for other entities, such as a foreign LLC, may differ.
Choosing the right name for your LLC is crucial. The name should be distinctive, memorable, and compliant with Washington’s naming regulations. The state has a business name search, or use our Washington business name search page, and we’ll walk you through the process step by step.
Washington state law requires you to include some variation of “Limited Liability Company” as the name’s suffix. You can end your company’s name with the full “Limited Liability Company,” shorten it to “Limited Liability Co.,” or use the abbreviations “LLC” or “L.L.C.”
The state additionally prohibits certain words and combinations of words from appearing in LLC business names. You can’t use words that would suggest your limited liability company is a financial institution, like “banker,” “banking,” “trust,” or “cooperative.” You also can’t combine the words “trust” and “loan.” Finally, you may not use any combination of two or more of the following words: “savings,” “association,” “society,” “home,” “loan,” or “building.”
If you’re looking to form a Washington PLLC, you’ll need to pick a unique name, just like a standard LLC. But the specifics of what you include in your name look a little different. Specifically, instead of “LLC,” PLLCs need to end their name with “professional limited liability company,” “professional limited liability co.,” or the abbreviation “PLLC” or “P.L.L.C.”
You’ll also need to ensure that your name complies with any specific requirements enacted by your industry’s regulatory board. For example, a dental service PLLC is required to include the full name or surname of each member in the business name, followed by specific abbreviations. Please consult your regulatory board for specifics about your industry’s naming requirements.
As you search for available business names, check if relevant domain names are available for those business names. A website is an affordable marketing tool that can drive customers to your business. You want a domain that aligns with your LLC name, making the website easy for search engines to find. Check out our domain name registration and business name search services for more information.
The state-level search doesn’t take into account trademarks. The state could approve your LLC’s name, and you can spend money on signage, business cards, advertising, etc., only to have someone serve you notice that you’re infringing on their trademark.
To see if your desired LLC name is trademarked on a national level, do a search on the U.S. Patent and Trademark Office website. You can also try applying for a trademark of your own, but this can be a long and costly process.
To see if your name is trademarked at the state level, the Washington Secretary of State site has a trademark search engine. You can also apply for a state trademark of your own for a fee.
We should mention here that neither of the methods above is a guarantee that no one will file a trademark infringement lawsuit against you. The more research you can do on your desired business name (conducting Internet searches or even consulting a trademark attorney, etc.) beforehand, the better.
You might not be ready to take the next step and file your Certificate of Formation right away. Washington gives you the option to reserve your intended name for 180 days by completing a name reservation form and paying a small fee.
If you plan to use an alternate name for your limited liability company, you’ll need to apply for a trade name, commonly known as a “Doing Business As” (DBA) name. You’ll first need to check that your trade name is available and compliant with Washington’s requirements. Unlike your LLC’s official name, your trade name should not have any business entity suffix, including “Limited Liability Company,” “LLC,” or “L.L.C.” The trade name should also not include any words relating to financial institutions, such as “bank,” “trust company,” “credit union,” or other similar words or phrases.
Once you’ve found an acceptable DBA name, you’ll need to register it. Our guide to Washington DBAs can give you the specifics.
Ready to Start Your Washington LLC?
Enter your desired business name to get started
Select a registered agent for your LLC. Every registered Washington business entity needs to have a registered agent (For more information, please see our what is a registered agent page). This is a person or entity acting as the point of contact for service of process (notification of a lawsuit) and other legal documents on behalf of the business. A registered agent’s service is invaluable in maintaining your LLC’s compliance. This service helps ensure that all legal documents are received and handled promptly.
The registered agent must have a Washington residency in the form of a physical street address in the state. If the agent is a business entity, it must have authorization to do business in the state. The agent must also be available in person during normal business hours to receive service of process.
As an LLC member, you can list yourself as a Washington registered agent for your company; however, this option isn’t always in your best interest. If you’re served with a lawsuit, for example, you don’t want to receive this paperwork at your place of business, with customers and clients around. Plus, you probably don’t want to be bound to your office all day in case a process server shows up.
Instead, consider our professional Washington registered agent service. We can help you fill this legal requirement and make sure all important documents get to you in a discreet and time-efficient manner.
When you use our registered agent service, we’ll provide you with an agent who’s available to receive important legal and Secretary of State notices in person. This gives you the peace of mind of knowing you’re in compliance with the registered agent requirements.
As a bonus, our service also helps keep you organized. When you get important documents, we’ll quickly inform you and keep them together in your online digital dashboard so that you can view, download, and/or print them whenever you want. It’s better than rummaging through piles of papers to try to find important legal documents when you need them.
Submit your LLC paperwork to the state. Once you’ve decided on a business name and appointed a registered agent, the next step is making your Washington LLC official. To do so, you’ll need to complete a Washington LLC and file it with the Washington Secretary of State. Once approved, this is the official document that formally establishes your LLC as a recognized legal entity in Washington.
To officially form your LLC, filing with the Secretary of State is a key step. The Washington Secretary of State oversees the legalities and ensures your business complies with state laws.
To complete your certificate, you’ll need:
In some states, LLCs and PLLCs file the same version of the Certificate of Formation, but that’s not true in Washington. PLLCs will need to file a separate version of the form, the Certificate of Formation of a Professional Limited Liability Company. That said, most of the information this form requests is identical to the standard LLC form. The primary difference comes in the naming section. There’s also a section that attests that all of your members are licensed in the PLLC’s stated profession.
Please make sure you have the correct version of the form to help streamline your filing process.
Obtaining a Certificate of Formation from the Washington Secretary of State is essential to legitimize your LLC. This certificate serves as the legal foundation of your business in Washington.
The Washington Secretary of State prefers online filing but does accept paper forms for an extra fee. Once accepted, your LLC will receive a Washington State Unified Business Identifier (UBI). Be sure to keep a record of that number, as you will use it when dealing with other state agencies.
Within 120 days of forming an LLC in Washington, you’re required to file an Washington initial report, which is really the first annual report your LLC will file every year.
If this sounds overwhelming, don’t worry. Take a look at our business formation plans and let our team do the work for you. Once the Washington Secretary of State approves your LLC, your state paperwork will be available on your ZenBusiness dashboard, where you can keep it and other important business paperwork digitally organized.
In addition, we offer customized business kits to help you keep these important documents organized and looking professional. Whether it’s an operating agreement, member certificate, business contracts, compliance checklists, transfer ledgers, or anything else, you can be sure it’s all in one safe place.
Adopt an LLC operating agreement. An operating agreement is a legal document where you put in writing how the business will run, the breakdown of responsibilities, how profits will be shared, and more. (For more information please see our operating agreement definition page.) All members (owners) of the LLC will need to approve and sign it, making it a binding contractual relationship between the members. Washington doesn’t require a business to have an operating agreement, but most experts strongly encourage all LLCs to have one.
In the operating agreement, every member plays a vital role. It outlines each member’s responsibilities and the operational framework of the LLC, helping ensure a clear path for decision-making and conflict resolution. And, if a conflict arises and you have no operating agreement in place, the default state LLC laws will control the outcome.
What does a Washington operating agreement look like? What’s contained inside will depend on the specifics of your business, but there are a few things you’ll likely want to include:
Once it’s completed and signed, it should be kept in a secure location with other important business formation information. You don’t need to file it with the state.
If you’re unsure as to how to start creating an operating agreement for your LLC in Washington, then check out this guide. Make note that, if you decide to form your LLC with ZenBusiness, we offer a customizable operating agreement template to save you time researching and crafting the agreement yourself.
Get a federal Employer Identification Number (EIN). This is a nine-digit code the Internal Revenue Service (IRS) uses to identify businesses for tax purposes. Most Washington LLCs need this tax ID number, sometimes even those that are single-member LLCs with no employees.
Getting an EIN should be a priority, anyway, as it can help with practical things like opening a business bank account. You can use our EIN registration service to make it easy.
Note: As of December 3, 2024, a federal court temporarily paused enforcement of the Corporate Transparency Act, which requires businesses to report their beneficial ownership information to FinCEN. Although not mandatory, FinCEN is still accepting beneficial ownership filings. You can learn more about the current status of the beneficial ownership information (BOI) report on our BOI Report Requirements Timeline.
The Corporate Transparency Act went into effect in the beginning of 2024, meaning LLCs and other small businesses have a new requirement: filing a beneficial ownership information report, or BOI report. Under the terms of the act, reporting companies are required to disclose information about their beneficial owners. This, according to the act, will help deter financial crimes by making it more difficult to hide money laundering and other illicit activities behind shell corporations.
When you file your BOI report, you’ll be asked to provide the name, address, and identifying documents for each of your LLC’s beneficial owners. A beneficial owner is anyone who holds 25% or more of your LLC’s ownership interest, gets significant economic benefit from its assets, or exercises substantial control over it. You will submit this information to the Financial Crimes Enforcement Network (FinCEN), and you can do so online or by PDF upload.
Failing to provide this ownership information can have severe criminal and civil penalties, so be sure to file — and on time. For LLCs that organize in 2024, the due date is 90 days after Washington approves your Certificate of Formation. LLCs that organize in 2025 and beyond will see that due date cut to just 30 days post-approval. Any LLCs that organized prior to 2024 will have until January 1, 2025. If you’d like to learn more about this filing, check out FinCEN’s website. And if you’d like help filing this new form, our BOI report filing service has you covered.
Once your Washington State LLC is established, your job isn’t quite finished. There are still a few post-formation steps to tackle to help ensure that your LLC operates compliantly, paving the way to success.
There’s a very good chance that your LLC will need business licenses or permits to operate compliantly. For starters, Washington has a general business license that most business entities need to get. Cities and counties sometimes require a general license of their own, too.
It’s also not uncommon for businesses to need an industry-specific permit. You’ll have to do some research to learn if any industry permits apply to your company. If this sounds overwhelming, our business license report can help streamline this process for you.
It’s vital to implement an accounting system to manage finances, track expenses, and prepare for taxes. Good accounting can also help you have a comprehensive view of your business’s progress.
There are lots of options available to you for an accounting system: a simple but thorough spreadsheet, accounting software, hiring a professional bookkeeper, or even just using our ZenBusiness Money app. The priority is that you get an accounting system in place and use it faithfully.
Once you’ve secured your EIN, you’ll be able to open a business bank account. It’s important to keep separate accounts for your business and your personal banking, as failing to do so might land you in legal trouble and open your personal assets up to creditors or those looking to file a lawsuit against your business.
To help you avoid this, we offer a discounted bank account for new businesses. This allows for unlimited transactions, online banking, a debit card, and more. When you want to authorize others in your business to use the account, we offer a banking resolution template to simplify the process.
If you don’t feel confident in your financial skills quite yet, try ZenBusiness Money. It can help you create invoices, receive payments, transfer money, and manage clients all in one place.
Keep abreast of legal changes and requirements, including tax obligations and employment laws, to maintain compliance. Laws and tax rates are subject to change at any time, and it’s your responsibility to stay informed and, of course, adhere to the changes that affect your business.
It can be helpful to occasionally consult with a Washington attorney or CPA to stay informed about relevant changes in a timely manner.
If you’ve made a mistake in one of your business formation documents, don’t worry; you can correct the issue. To amend an item like your registered agent address, your contact information, or something similar, you’ll need to file an “Amended Certificate of Formation” form with the Washington Secretary of State.
To do this, you must complete the amendment form, detailing the changes being made and the reasons for these changes. Once completed, submit the form along with the required fee to the Secretary of State. It’s important to ensure all information is accurate to avoid further issues or spending extra money on non-refundable filing fees.
If you’re thinking of forming an LLC in Washington, there are actually a couple of different types available, each suited to different business needs.
If you’re a solo dreamer in the Evergreen State, then a single-member LLC might be a perfect fit. With this structure, you take charge as the sole owner while also enjoying the liability shield that LLCs offer.
If you have one or more friends or family members excited to start a business with you, then a multi-member LLC could be a great way to team up with security. A multi-member LLC helps ensure each member’s input is valued while splitting profits, losses, and responsibilities according to the agreed terms.
A professional limited liability company (PLLC) is a company formed for licensed professionals such as medical doctors, dentists, and attorneys. It provides liability protection while meeting professional licensing requirements. PLLCs do not shield members from personal malpractice claims but protect against claims made against other members.
Sometimes, an LLC has to close down; maybe it’s time to retire or move on to the next venture. If that’s the case, you’ll need to formally dissolve your LLC to avoid ongoing annual fees and tax liabilities.
Dissolving an LLC in Washington State requires careful steps. To start, a formal decision to dissolve must be made, usually through a vote in accordance with the LLC’s operating agreement. Following this, a “Certificate of Dissolution” must be filed with the state.
After filing, the LLC must settle any debts, liquidate its assets, and distribute any remaining assets to members. It’s crucial to also notify creditors and settle all tax obligations to ensure a smooth dissolution process. For more information, check out our Washington dissolution guide.
Once you’ve finished the steps above, you’re (literally) in business! You’ve taken the first steps toward building your dream company. But there’s a lot more to know than just how to start an LLC in Washington state.
You need to know about things like hiring employees, getting business licenses and permits, getting additional financing if you need it, how to make changes in your business, and how to stay in compliance with the government.
Our many services can not only help you form your LLC (our LLC formation service starts at $0), but our business experts can also give you long-term business support to help start, run, and grow your business.

The cost of starting an LLC in Washington State depends on your situation. Filing a Certificate of Formation requires a fee, and you must also provide your Initial Report within 120 days, which will cost an extra fee. The cost varies based on filing method, and you’ll pay more if you need expedited service. The total cost could range from $200 to around $300 based on these factors.
In addition to this cost, you may have state and local business licenses, permits, and insurance to pay for when starting your Washington LLC. This will depend largely on the type of business you run. For example, if you work in the food service industry, you need a state business license, health permit, and possibly a liquor permit — to name just a few. LLCs with employees will need workers’ compensation insurance, as well.
LLCs in Washington offer flexibility and protection for business owners. By choosing the LLC structure, entrepreneurs combine the advantages of both corporation and partnership business models. Limited liability is a cornerstone of the LLC structure. It usually provides protection for your personal assets against the liabilities of your business operations.
LLCs aren’t the only type of business you can form in Washington. However, about 90% of our customers choose to form an LLC over all other types. Compared to corporations and other forms of entities, LLCs come with enticing benefits. The reporting requirements for LLCs are less extensive than those of a corporation, for instance, and they allow for flexible management structures.
Forming your LLC in Washington state means you’ll reap the following added benefits:
Your Washington LLC will likely need to pay taxes on the federal, state, and local levels.
At the federal level:
At the state level:
At the local level:
Sales tax:
State employment tax:
Workers’ compensation premiums:
It depends. Your Certificate of Formation will be processed with the Washington Secretary of State in the order in which it is received. Online filing is the quickest way; your LLC paperwork is usually processed within two business days. Washington has options for expediting your filing for an additional fee.
No. The operating agreement is kept internally by the members.
As an LLC, you have different tax classification options to choose from. The majority of LLC owners opt for the default status. Under this setup, profits are passed through the LLC to the members. You pay taxes only on your individual income tax return. This is unlike most corporations, in which profits are taxed twice, first at the business level and again at the individual shareholder level.
If you meet the IRS criteria, you could also have your LLC taxed as an S corporation (please see our What is an S Corp? page). For some LLCs, this can decrease the amount of taxes the members would pay for Social Security and Medicare.
Alternatively, you can have your LLC taxed as a What is a C corporation? federally. A C corporation can take advantage of the widest range of deductions, but this is usually advisable only for much larger and more profitable LLCs.
A tax professional can advise you as to which tax status makes the most sense for your business.
Note that the LLC will likely be subject to other state taxes, however. Washington requires LLCs to pay business and occupation taxes, for instance. These are calculated based on your business’s gross receipts. The tax rate varies depending on the type of business.
A series LLC is a special business structure that allows multiple limited liability companies to operate under one “parent” organization. Washington does not allow Series LLCs (only a minority of states do).
All LLCs in the state of Washington need to file an Initial Report within 120 days of being formed. It should be submitted to the Washington Secretary of State. The Initial Report is the first version of the Washington annual report required each year.
You’ll first need to review your operating agreement, as this document should outline how your business handles the addition of new LLC members. Once the addition of the member has been agreed upon by the members, you’ll need to amend your operating agreement or draft a new agreement entirely to document the changes. You may also need to amend your Certificate of Formation with the state.
Yes, any LLC doing business in the state is required to file an annual report. This rule applies regardless of whether it’s a domestic LLC or a foreign LLC authorized by the Washington Secretary of State to conduct business in Washington. The Washington LLC annual report can be filed online or mailed in. In both cases, the filing fee is the same — $70.
Staying compliant with the Washington Secretary of State guidelines is vital for your LLC’s longevity. Regular filings and adherence to state regulations, as outlined by the Washington Secretary of State, keep your business in good standing.
Formally, you can. However, there are some pitfalls you need to be aware of. These pitfalls can be avoided with ZenBusiness’s professional registered agent service.
Before starting the dissolution process, the members of an LLC should vote to dissolve it. For the subsequent steps, please refer to our Washington business dissolution guide.
An LLC registered in a different state, also referred to as a foreign LLC, should undergo registration with the Washington Secretary of State before it can conduct business in the state.
Yes, but not always. While Washington’s statutes don’t prohibit professionals from different fields from forming a PLLC together, the individual rules of that profession might. For example, Washington’s Rules of Professional Conduct prohibit lawyers from sharing fees with non-lawyers.
By default, PLLCs pay taxes as “pass through” entities. This means that the PLLC only pays applicable taxes through its members on their personal income tax returns. In comparison, professional corporations are typically “double taxed,” which means they also pay taxes at the entity level. Taxes can be complicated, so we highly recommend chatting with a Washington tax attorney for customized guidance about your unique circumstance.
