Here are the steps to forming an LLC in Washington

Starting an LLC in Washington is a straightforward process that offers numerous benefits, including personal asset protection and tax flexibility. In this guide, we’ll take you through the necessary steps to form your LLC, ensuring compliance with Washington’s legal requirements. Let’s dive into the process step by step.

Step 1: Search Your LLC Name

The first step in forming an LLC in Washington is to select a unique name for your business. Your LLC’s name will identify your company and represent your brand. In Washington, there are several important rules and requirements to follow when choosing a name.

LLC Name Requirements

To ensure your name complies with state regulations, your LLC name must meet the following criteria:

  • Unique: The name you choose must be distinguishable from other businesses already registered in Washington. This means no two LLCs can have identical names. To verify availability, you should conduct a name search on the Washington Secretary of State website.
  • Include LLC Designators: The name of your LLC must end with one of the following designators:
    • “Limited Liability Company”
    • “Limited Company”
    • “LLC”
    • “L.L.C.”
  • Prohibited Words: There are certain words that cannot be included in your LLC name unless you have special approval or licensing. For example, words like “bank,” “insurance,” or “trust” may be restricted.

How to Check Name Availability

To ensure your name is available, you can use the Washington Secretary of State’s Name Search tool. This tool will help you determine if your desired name is already taken or if you can proceed with it.

You should also consider reserving your LLC name if you’re not quite ready to file your formation documents. You can reserve a name for 180 days for a small fee. This allows you time to prepare your paperwork while protecting your chosen name.

Step 2: Choose a Registered Agent

A Registered Agent is an individual or business entity that is authorized to receive official documents, such as legal notices or tax documents, on behalf of your LLC. Every LLC in Washington is required to designate a Registered Agent when forming the business.

Who Can Be a Registered Agent?

There are two main options for choosing a Registered Agent in Washington:

  • Individual: This can be you, another member of your LLC, or any other individual who is a Washington resident. This person must have a physical address in Washington and be available during business hours to accept official documents.
  • Professional Registered Agent Service: You can hire a third-party company that provides Registered Agent services. Many businesses choose this route for convenience, privacy, and to ensure they never miss an important document. A Registered Agent service will handle receiving and forwarding legal documents and state notifications on your behalf.

Recommended Registered Agent Service: Northwest Registered Agent

One highly recommended service for Registered Agents is Northwest Registered Agent. They offer a secure and reliable service that not only ensures your LLC’s compliance but also provides privacy protection by using their address on your formation documents. Northwest Registered Agent is known for their excellent customer service and straightforward pricing, making it an ideal choice for LLC owners.

Step 3: File LLC Certificate of Formation & Initial Report

Once you’ve chosen a name and a Registered Agent, you’re ready to officially form your LLC by filing the Certificate of Formation. This document officially registers your LLC with the state of Washington.

What is the Certificate of Formation?

The Certificate of Formation, also called Articles of Organization in some states, is the official document that you file with the Washington Secretary of State to legally establish your LLC. It provides the state with key information about your business, such as:

  • The name of your LLC.
  • The name and address of your Registered Agent.
  • Your LLC’s address (either a physical or mailing address in Washington).
  • The management structure (whether your LLC will be managed by members or managers).

Filing Fee & Processing Time

The filing fee for the Certificate of Formation is $200 if submitted online, or $180 if mailed. After filing, it usually takes about 12 to 14 business days for your LLC to be processed and approved if filed online. If you file by mail, the processing time can take 5-6 weeks.

Additionally, you must file the Initial Report within 120 days of forming your LLC. This report includes similar information to the Certificate of Formation, but it’s required to provide more detailed information about your LLC’s activities and members. You can file the Initial Report online, which is free if filed with the Certificate of Formation. If filed separately, the fee is $10.

Step 4: Create an Operating Agreement

Although Washington does not require LLCs to have an Operating Agreement, it’s highly recommended that you create one. An Operating Agreement is a legal document that outlines the ownership and management structure of your LLC. It helps to clarify how your LLC will be run, reducing the chance of conflicts among members down the road.

What Should Be Included in an Operating Agreement?

Here are some of the important elements your Operating Agreement should include:

  • Ownership and Member Roles: The percentage of ownership for each member, as well as their role and responsibilities in the company.
  • Management Structure: Whether your LLC will be managed by members (member-managed) or by appointed managers (manager-managed).
  • Profit Distribution: How profits and losses will be divided among members.
  • Voting Rights: Details about how decisions will be made, whether it’s a majority vote or unanimous.

Having an Operating Agreement can also strengthen the legal protection of your LLC status. It helps maintain the distinction between your personal and business assets, which is essential for keeping your limited liability protection intact.

Step 5: Get an EIN for Your LLC

An Employer Identification Number (EIN) is a unique identification number assigned to your LLC by the Internal Revenue Service (IRS). It’s similar to a Social Security Number but for your business. An EIN is required for a variety of purposes, such as:

  • Opening a business bank account.
  • Hiring employees.
  • Filing taxes.

How to Obtain an EIN

You can apply for an EIN directly on the IRS website. The process is free and typically only takes a few minutes. You’ll receive your EIN immediately after completing the application.

If you prefer, you can apply for an EIN by mail or fax, but online is the fastest method.

Step 6: Get Business Licenses and Permits

After forming your LLC, you may need to obtain business licenses and permits depending on your type of business and location.

Types of Licenses and Permits

  • State Business License: Most businesses in Washington are required to have a state business license. You can obtain this license from the Washington State Department of Revenue. The license is generally required for businesses that engage in sales, services, or certain professional activities.
  • Local Permits: Depending on where your business is located, you may need to apply for local permits through your city or county government. These can include health permits, building permits, or zoning permits.
  • Specialized Licenses: If you plan to operate a business that requires a specific professional license (e.g., a lawyer or healthcare provider), you’ll need to obtain those as well.

You can use the Washington Business Licensing Wizard to help determine which licenses and permits you’ll need.

What Do I Do After My LLC is Approved?

After your LLC is approved, there are still a few important steps you need to take to maintain compliance with state and federal regulations.

How Much Does a Washington LLC Annual Report Cost?

Washington LLCs are required to file an Annual Report each year to keep their business in good standing. The filing fee for the Annual Report is $60. It’s important to file your Annual Report on time to avoid penalties or the risk of your LLC being administratively dissolved.

When is the Annual Report Due?

The due date for your Annual Report is the end of the month in which your LLC was formed. For example, if your LLC was formed on June 15th, your Annual Report will be due by June 30th of each subsequent year.

When is My First Annual Report Due?

Your first Annual Report is due one year after your LLC’s formation. However, if you file your Initial Report at the time of formation, you won’t need to file a separate Annual Report until the following year.

How Do I File My LLC Annual Report?

The Annual Report can be filed online through the Washington Secretary of State’s website. You will need to provide updated information about your LLC, such as its address and the name of your Registered Agent. The filing fee is $60, and you can pay with a credit card.

How Will My LLC Be Taxed?

In Washington, LLCs are not subject to a state income tax, but they are required to pay the Business & Occupation (B&O) tax. The B&O tax is based on the gross receipts of your business and is categorized by business activity. The rate varies depending on your industry.

If your LLC has employees, you will also need to withhold state and federal payroll taxes and pay unemployment insurance taxes.
