How to Start an LLC in Washington StateAfter Starting Your Washington LLCBusiness & Occupation (B&O) Tax in WashingtonEstimate Your Washington B&O TaxWashington State Foreign LLCWashington LLC Formation ReviewF.A.QsHow to Start an LLC in Washington State
An LLC (aka Limited Liability Company) is a hybrid business entity combining a corporation’s characteristics with a partnership or sole proprietorship. It separates your personal assets from your business assets, thus giving you personal asset protection. For an LLC, members' personal assets are not affected by business debts. However, in some cases, if the LLC is sued for business debts, courts might pierce the corporate veil and use the owner's personal assets to meet the corporation's liabilities.
If you wish to start an LLC in Washington State, you must file your Certificate of Formation with the State and pay a filing fee of $200 (online and $180 by mail). While it's the most important step, it's not the only one. There are 4 other crucial steps to follow to get your LLC formed in Washington. Below are all 5 steps that explain everything you need to do to start a Washington State LLC in 2026. Let's get started!
Step 0Decide on the Structure and Nature of the Business
Before you start filing your LLC in Washington, you must decide on the structure of your LLC (whether it is a Single-member or a Multi-member LLC). A single-member LLC is a business structure where only one individual runs the company. This type of limited liability company (LLC) provides legal protection to its owner and enables them to operate their business while taking advantage of certain tax benefits. In contrast, a traditional multi-member LLC must have at least two members involved in the company’s management and ownership.
For both types of structures, the process of establishing is the same in Washington. The tax burden might be different if you chose a different tax structure while filing the certificate of formation.
LLC vs S-Corp
An LLC is a business structure that has the right to elect any tax structure. Despite having a pass-through tax advantage, many LLCs, for several reasons, elect a different business structure for tax purposes. An S-Corp is one of those business structures that LLCs can elect. The S-Corporation is a type of corporation that is less complicated than a C-Corporation and has vast tax benefits.
With an S-Corp, the LLC can still enjoy a pass-through taxation. However, the federal income tax will be calculated on the basis of the salary of the owner and the return he/she gets on their share of the company. There is no corporate income tax or problem of double taxation in an S-Corp. A single-member or a multi-member LLC can elect an S-Corp tax structure. However, in the case of a multi-member LLC, make sure that the number of members does not exceed 100 to be an S-Corp.
If you have a single-member LLC, electing an S-Corp can save a chunk of tax for you. As a single-member LLC, the owners have to pay about 15.3% self-employment tax. However, if you have an S-Corp tax structure, no SE tax is payable by the LLC. Read more on what tax forms LLCs file.
Step 1Decide on a Name for Your Washington State LLC
The first step in forming a limited liability company in Washington state is to give a proper name to your LLC. Before you name your business, you must know that the name should be easy to remember, available in the state, and follow all the LLC naming guidelines.
Washington State LLC Naming Guidelines
There are a few specific requirements all LLCs in Washington State must follow while naming their Company. Some of the most important requirements are as follows:
-
"Limited Liability Company", "Limited Liability Co.", "LLC", "LC", "L.C.", and "L.L.C." - any one of these has to be used as a suffix in your business name.
-
You cannot use any name for your business that is confusing or misleading. Terms such as "Treasury", "State Department", "FBI", "CIA", etc. shouldn't be included.
-
Terms like "Bank", "University", "Attorney", "Doctor", etc, can be added only after the additional requirements by the Washington State Government are fulfilled.
-
(Optional) It's better to name your business something for which your desired domain is available.

Reserve Business Name for Future
If you do not wish to file your LLC right now but want to hold the name you have decided on, then you can reserve your LLC name for 180 days. To keep the name, you must file a name reservation application and pay $30 to reserve your name with the Washington State Secretary of State. By paying $50, you can expedite the process.
Business License and Trade Name in Washington
Most Washington businesses need a state Business License. The Business License Application costs $90, and businesses receive a Unified Business Identifier (UBI). Trade names register through the same Business License Application. The trade name registration fee is $5.
Do I have to include LLC in my company email/domain?
It is not legally mandatory to use the word LLC in your domain name or email. If you want, you can use it. However, it is recommended not to use LLC in the domain name. A domain name should be short and easy to remember.
Step 2Assign a Registered Agent in Washington State
The second step to forming an LLC in Washington State is to appoint a Registered Agent. A registered agent is a person or business entity working on your LLC's behalf. This person or business will receive important tax forms, legal documents, all notices of lawsuits, and other official government correspondence in Washington State. Hence, hiring a competent Washington Registered Agent for your LLC is necessary.
Yes, you can be your own registered agent if you are at least 18 years old and have a physical street address in Washington State. Most LLC formation companies also provide registered agent services. Below are two great LLC formation services; even if you buy their cheapest plan (normally $0), you also get registered agent service and other services at a very reasonable price.
- Free LLC formation
- Access to Legal Support
- Trustworthy and established reputation
- Flat pricing for all services
- Basic business filing services
- A+ BBB Accredited
These two are our top recommendations for LLC service, as they are competent and authorized to conduct business in Washington State. Some LLC formation services also offer standalone Washington State registered agent services. You can purchase only Registered Agent services without purchasing any other LLC formation services. This standalone service might become handy if you are doing it yourself and don't want to disclose your home address, or you don't want to pierce the corporate veil.
Who Can Be a Registered Agent?
A person above 18 years of age and who has a physical address in the state of Washington can be a Registered Agent. A Registered Agent can be an independent person or a business entity. One is responsible for handling all the legal documents on the LLC's behalf.
Can I Be My Own Registered Agent?
Yes, you can be your own registered agent if you are at least 18 years old and have a physical street address in Washington State. To become a registered agent, you must have the authority to conduct any type of business in Washington State.
Why Shouldn't I be My Own Registered Agent?
There are a few reasons why you shouldn't be your own registered agent. The address of the registered agent is used to communicate with the SOS or for any legal activities. If you are your own registered agent, you might have to upload your personal address to the public forum. Besides, the registered agent must be at the address during business hours. It won't be easy for you as you also have to take care of other things in your LLC. Hence, it is wiser to appoint a separate entity as your registered agent.
What is Piercing the Corporate Veil in an LLC?
If an LLC is sued in Washington State, in some cases, courts might decide to lift the corporate veil, which means the owners of the LLC will be personally liable for their business debts. They might have to forgo their personal assets to repay their business debts. This is called piercing the corporate veil, where personal and business assets are no longer separated. Your personal assets can be protected if you have enough capital and all your LLC documents are properly filed.
Registered Agent Consent Application
In Washington State, there is no separate Consent Letter to be produced to the Secretary of State. At the time of change of Registered Agent (or the name or address), the new Registered Agent has to sign the consent letter. It comes with the Application form to Change the Registered Agent. There is no filing fee to be paid for it. For more information on the same, read our guide on Washington State Registered Agent.
Step 3File Certificate of Formation in Washington State
The third and most important step in forming a Washington State LLC is to file the Certificate of Formation. This Washington State Certificate of Formation is a legal document that is required to register your business with the Washington State Secretary of State. It costs $200 (online and $180 by mail) to file your formation certificate in Washington State.
The Certificate of Formation includes details like the name of the LLC, the registered agent's name, address, and the company's structure (member-managed or manager-managed). Before hiring employees in Washington State LLC, one should know the rules and regulations thoroughly. Also, if you are expanding your existing business (an LLC) in other states to Washington State, you must register as a Washington State Foreign LLC.
How to File Online
Go to the Secretary of State Online Service. You will get the online service page. If you are already a subscriber, then click on the "Log in to Subscribe Account" option and log in with your credentials.

Read more about the Washington State Certificate of Formation for online registration.
Processing Time: Online filings process in approximately 5 business days. Expedited service costs $100 extra, while same-day processing costs $150. Mail filings take approximately 14 business days.
Step 4Create Your Washington State LLC Operating Agreement
Moving on to the fourth step, filing your operating agreement. An operating agreement is a document that legally outlines the proprietorship and operating procedures of your LLC. This document is vital as it ensures that all business owners are on the same page regarding how they operate, thus reducing future conflicts.
When it comes to filing a Washington State LLC Operating Agreement, the state does not require you to have a comprehensive operating agreement, but it is ideal to have one that contains all the details of your business operation, which helps in making future business decisions, especially if you decide to dissolve Washington State LLC later. Hence, having an operating agreement may not be necessary, but it is surely ideal.
Step 5Filing a Washington State LLC EIN
The Employer Identification Number (aka EIN) is a nine-digit number given by the Internal Revenue Service (IRS) to make it easier to identify the type of business for tax purposes and taxes in general. The EIN is necessary for any active business or any form of business.
For an LLC in Washington, an EIN is required when the LLC hires employees. Apart from that, banking services, tax filings, and many other government documents require an LLC to obtain an EIN in Washington. On the other hand, if your LLC is based in another state (home state) and you are expanding your business in Washington, you must get an EIN to establish a Foreign LLC in Washington.
To obtain an EIN (aka FEIN), one must fill out a form (Online or by mail) and submit it to the IRS. Enter details of your LLC, and finally, complete the form and send it to the address given. You can also get an EIN Assistant to help you with the process.

After Starting Your Washington LLC
After forming your LLC, there are still some things that you will need. The most important thing is to separate your business and personal assets. LLCs have limited liability protection that protects your personal assets from business liability. This is called a corporate veil. However, the corporate veil can be lifted or pierced by the court if the LLC is sued. In that case, the owners of the LLC become personally liable for their corporate debts. A few things, like appointing a legit registered agent, having enough capital, and filing all the major documents with the state, can save the LLCs from being pierced through the corporate veil.
Washington requires LLCs to file a free Initial Report within 120 days of formation. The Initial Report can be filed up to 180 days early when submitted with the Certificate of Formation. After that, the Annual Report is due by the last day of the LLC’s anniversary month. A $25 delinquency fee applies to late Annual Reports, and an LLC may be administratively dissolved if its Annual Report remains delinquent for 120 days.
BOI Report Filing
According to the Corporate Transparency Act, foreign entities registered to do business in the U.S. must file a BOI report with FinCEN. However, note that as of March 26, 2025, FinCEN issued an interim final rule removing BOI reporting requirements for all domestic U.S. companies and U.S. persons. If your LLC was formed under U.S. law, you are currently exempt from BOI filing obligations — consult the FinCEN BOI page for the latest guidance, as this regulatory area remains subject to change.
Apart from that, there are a few things you need to take note of,
-
Get a company business bank account
-
File Washington State business permits & licenses
-
Get general liability insurance and professional liability insurance with coverage for employees.
-
File a Washington State LLC annual report or biennial report
This page has provided you with steps for LLC formation and filing processes. You now have to remember upcoming filing deadlines and filing fees or filing costs, including fees for late filing, to make sure your LLC is up-to-date.
Cost of Washington State LLC
LLCs can be formed for a very low price. Apart from the mandatory state filing fees, you don't have to bear additional service charges if you do it yourself. The following are the fees and taxes LLCs in Washington State must pay to register and run a business in the state. Forming an LLC is no doubt cost-effective compared to other business structures. However, there are other fees and taxes you may need to pay, such as the name reservation fee, LLC filing fee, and sales tax if applicable. Here are the main fees and taxes you must pay while forming your limited liability company in Washington State,
| Fees/Tax | Amount to be Paid |
|---|---|
| Name Reservation Fee | $30 |
| Name Reservation Fee (Expedited) | $50 |
| Certificate of Formation Fee | $200 (online and $180 by mail) |
| LLC Annual Fee | $70 |
| Sales Tax | 6.5% |
In Washington State, an Annual Report has to be produced every year. It costs $70. Washington's state sales tax rate is 6.5%, but local taxes can increase the combined rate to around 10% or more in areas such as Seattle. Sales tax applies only to taxable sales and is not an annual LLC fee. Washington also expanded its sales tax to cover certain IT services, technical support, and similar services under changes that took effect in 2025. Read our guide on LLC costs in Washington State for more information.
Business & Occupation (B&O) Tax in Washington
Washington does not impose a state personal or corporate income tax. Instead, most businesses are subject to the Business & Occupation (B&O) Tax, which is based on gross receipts with no deductions for business expenses. This means an LLC may owe B&O tax even if it operates at a loss. B&O tax rates vary depending on the type of business activity. Retailing is taxed at 0.471%, while wholesaling and manufacturing are taxed at 0.484%. Service businesses are subject to tiered rates of 1.5%, 1.75%, or 2.1%, depending on their annual gross income.
A 0.5% surcharge may apply to businesses with more than $250 million in annual gross income. Small businesses may qualify for the Small Business B&O Tax Credit, which can reduce or eliminate their B&O tax liability. The 2.1% top service B&O tax tier took effect October 1, 2025, while a 0.5% surcharge for businesses with more than $250 million in annual gross income took effect January 1, 2026. Standard retailing, wholesaling, and manufacturing rates are scheduled to increase to 0.5% on January 1, 2027.
Estimate Your Washington B&O Tax
Washington's Business & Occupation (B&O) Tax is generally based on a business's gross receipts, rather than its net profit. The applicable tax rate depends on the classification of the business activity, such as retailing, wholesaling, manufacturing, or services.
To estimate your B&O tax, determine your business classification and calculate the tax based on your gross receipts and the applicable rate. Small businesses may qualify for the Small Business B&O Tax Credit, which can reduce or eliminate the amount of B&O tax owed.
For current B&O tax classifications, rates, and credit information, see the Washington State Department of Revenue B&O Tax rate information.
