Washington State is a popular choice for entrepreneurs due to its strong economy, tech-friendly ecosystem, and no personal state income tax. If you’re planning to start a business, forming an LLC in Washington offers flexibility, legal protection, and credibility.

This guide explains how to register an LLC in Washington step by step, using clear and practical language so you can move forward with confidence.

Step 1: Choose a Name for Your Washington LLC

Your LLC name must be unique and distinguishable from existing businesses registered with the Washington Secretary of State. It must include one of the following:

Step 2: Appoint a Registered Agent in Washington

Washington law requires every LLC to have a registered agent. This person or company receives legal notices, government correspondence, and compliance documents on behalf of your LLC.

Your registered agent must:

• Have a physical address in Washington
• Be available during normal business hours

Many business owners use professional services like PrimeRegister US LLC to ensure compliance, privacy, and timely handling of legal documents.

To officially form your LLC, you must file a Certificate of Formation with the Washington Secretary of State.

Information required includes:

Step 4: Create an Operating Agreement

Washington does not legally require an operating agreement, but having one is highly recommended.

An operating agreement defines:

• Ownership percentages
• Roles and responsibilities of members
• Profit and loss distribution
• Rules for decision-making

This document protects your LLC internally and strengthens your legal standing.

Step 5: Obtain an EIN from the IRS

An Employer Identification Number (EIN) is required if your LLC:

• Has multiple members
• Plans to hire employees
• Wants to open a U.S. business bank account

The EIN is issued by the IRS and is free to obtain.

Step 6: Apply for a Washington Business License

Washington requires most LLCs to obtain a state business license through the Business Licensing Service (BLS).

This license allows you to:

• Operate legally in Washington
• Register for state taxes
• Apply for local permits if needed

Additional licenses may be required depending on your business activity.

Step 7: Open a Business Bank Account

Opening a dedicated business bank account helps maintain liability protection and keeps finances organized.

Typically required documents:

• Certificate of Formation
• EIN confirmation
• Operating Agreement

Separating personal and business finances is essential for long-term success.

Step 8: Maintain Ongoing Compliance in Washington

Washington LLCs must file an Annual Report every year.

• Annual Report Fee: $60
• Due Date: By the end of your LLC’s anniversary month

Failure to file can lead to late fees or administrative dissolution.

Using a professional service like PrimeRegister US LLC helps business owners stay compliant and avoid missed deadlines.
