Establishing Your Enterprise in Washington State: A Professional’s Guide to LLCs and Corporations.
Washington State, a hub for innovation in technology, aerospace, and e-commerce, along with a significant agricultural and manufacturing base, presents a dynamic environment for businesses. For entrepreneurs seeking to establish or expand their operations in the Evergreen State, a critical foundational decision involves choosing the appropriate legal structure: a Limited Liability Company (LLC) or a Corporation. This choice significantly impacts your legal liability, tax obligations, administrative responsibilities, and future growth potential.
At Sure Financial and Tax Services LLC, we specialize in guiding businesses through the intricate process of entity formation and ongoing compliance in Washington. This comprehensive guide provides a professional overview of the core distinctions, advantages, and formation requirements for both LLCs and Corporations, empowering you to make an informed decision for your Washington enterprise.
The Washington Limited Liability Company (LLC): Flexibility and Personal Asset Protection
The LLC is a highly popular business structure in Washington, offering a beneficial blend of personal asset protection (similar to a corporation) with the operational simplicity and potential for pass-through taxation typically associated with partnerships or sole proprietorships. A key aspect of Washington’s tax landscape is the Business & Occupation (B&O) tax, which applies to LLCs (and corporations).
Key Advantages of a Washington LLC:
Limited Personal Liability: This crucial benefit shields your personal assets (such as your home, savings, and personal vehicles) from the LLC’s business debts, lawsuits, and other financial obligations.
Pass-Through Taxation (Federal Income Tax): By default, Washington LLCs are treated as “pass-through” entities for federal income tax purposes. This means that business profits and losses are passed directly through to the owners’ personal tax returns, avoiding the “double taxation” that can occur with C-Corporations.
LLCs also offer the flexibility to elect to be taxed as an S-Corporation or a C-Corporation if strategically advantageous.
No State Individual Income Tax: Washington is one of the few states that does not impose a state individual income tax. This means LLC profits passed through to owners are not subject to a state income tax at the individual level.
Operational Flexibility: LLCs generally have fewer formal requirements and ongoing compliance obligations compared to corporations. This allows for greater freedom in structuring management, decision-making, and profit distribution, typically outlined in an internal Operating Agreement.
No Publication Requirement: Washington does not require LLCs to publish notice of their formation in newspapers.
Washington Business Taxes Applicable to LLCs (as of July 2025 – Note on upcoming changes for 2025/2026/2027):
Business & Occupation (B&O) Tax: This is a gross receipts tax imposed on virtually all businesses operating in Washington. It is calculated on your gross income, not net profit, and applies to various business activities (e.g., retailing, wholesaling, manufacturing, services, etc.). Rates vary by classification:
Retailing B&O Tax: Currently 0.471%. Effective January 1, 2027, this rate will increase to 0.5%.
Wholesaling B&O Tax: Currently 0.484%. Effective January 1, 2027, this rate will increase to 0.5%.
Manufacturing B&O Tax: Currently 0.484%. Effective January 1, 2027, this rate will increase to 0.5%.
Service and Other Activities B&O Tax:
For businesses with gross income less than $1 million: 1.5%.
For businesses with gross income between $1 million and $5 million: 1.75%.
Effective October 1, 2025, for businesses and their affiliates with gross income of over $5 million, the rate will increase from 1.75% to 2.1%.
New Surcharge (Effective January 1, 2026): A new 0.5% surcharge will apply to businesses with Washington taxable income exceeding $250 million. This is in addition to other B&O taxes and is temporary, set to expire December 31, 2029.
B&O tax returns are filed monthly, quarterly, or annually depending on your estimated annual tax liability. There is a small business B&O tax deduction that allows businesses with gross income below a certain threshold to reduce or eliminate their B&O tax liability.
Sales and Use Tax: If your business sells tangible personal property or certain taxable services, you are required to collect and remit Washington sales or use tax. The statewide sales tax rate is 6.5%. Local taxing jurisdictions (cities, counties, and transit authorities) impose additional rates, bringing the combined rate up to 10.4% in some areas. You must obtain a Sales Tax Permit from the Washington Department of Revenue (DOR).
New Taxable Services (Effective October 1, 2025): Several services previously exempt will become subject to sales tax, including certain information technology services, custom website development, investigation and security services, temporary staffing, data processing, and advertising services.
Capital Gains Excise Tax (Effective January 1, 2025): An additional 2.9% excise tax will be imposed on Washington-sourced capital gains exceeding $1 million, bringing the total rate for gains over $1 million to 9.9% (this is on top of the existing 7% tax).
Unemployment Insurance (UI) Tax: If your LLC has employees, you will be required to register for and remit state UI taxes with the Washington State Employment Security Department. Rates vary based on employer experience.
Local Business Licenses & Permits: All businesses operating in Washington must obtain a state business license through the Master Business Application process via the Department of Revenue’s Business Licensing Service. Many cities and counties also require their own local business licenses and permits, which often can be obtained through the same Master Business Application system as many municipalities have partnered with the state for this “one-stop shop” service. Fees vary by locality.
Forming Your Washington LLC: Key Steps (as of July 2025)
Name Selection: Choose a unique business name that includes “Limited Liability Company,” “Limited Company,” or the abbreviations “LLC,” “L.L.C.,” “LC,” or “L.C.” The name must be distinguishable from other entities on file with the Washington Secretary of State (SOS). You can check for name availability using the SOS’s online Business Entity Search tool. You can optionally reserve an available name for a $30 fee.
Trade Name (DBA): If you plan to operate under a name different from your legal LLC name, you must register a Trade Name (DBA or assumed name) with the Washington State Department of Revenue’s Business Licensing Service as part of your Master Business Application. The fee for a trade name is typically $24.
Appoint a Washington Registered Agent: Every Washington LLC must designate a registered agent. This individual or entity must have a physical street address in Washington (not a P.O. Box) and be available during regular business hours to accept legal documents and official notices on behalf of your LLC. The registered agent must be an individual Washington resident over 18 or a business entity authorized to transact business in Washington. The registered agent must consent to this appointment.
File Certificate of Formation: This is the official document that legally creates your LLC. It is filed with the Washington Secretary of State. The filing fee is currently $200 (online) or $180 (by mail). The Certificate of Formation must include:
The LLC’s name and designation.
The principal office street address and mailing address.
The registered agent’s name and registered office street address.
The names and addresses of the LLC’s organizer(s).
The effective date (if a later date than filing, up to 90 days).
A statement whether the LLC is member-managed or manager-managed.
Prepare an Operating Agreement: While not legally mandated to be filed with the state, a comprehensive Operating Agreement is strongly recommended for all Washington LLCs, even single-member ones. This internal document outlines the ownership structure, member roles and responsibilities, profit and loss distribution, decision-making processes, and procedures for resolving disputes. It is a critical legal document for internal governance and for maintaining the separate legal existence of your LLC.
Obtain an Employer Identification Number (EIN): An EIN is a federal tax identification number issued by the IRS. You will need an EIN for federal tax filings, opening a business bank account, and hiring employees (even if you’re the only employee). You can apply for an EIN online for free through the IRS website.
Apply for a Master Business License & State/Local Registrations:
The Master Business Application (MBA) is a crucial step in Washington. It’s a “one-stop shop” system managed by the Department of Revenue’s Business Licensing Service. Through this application, you can:
Obtain a Unified Business Identifier (UBI) number, which is your primary state business identifier.
Register for the B&O tax, sales and use tax, and employer accounts (unemployment insurance, workers’ compensation).
Apply for most state-level professional and specialty licenses.
Apply for business licenses for many participating cities and counties.
The fee for the initial Master Business Application varies depending on the specific licenses and endorsements needed, but typically starts with a base fee (e.g., around $19 for the general business license).
File Annual Report: All Washington LLCs are required to file an Annual Report with the Washington Secretary of State. This report is due annually by the anniversary month of your LLC’s formation. The filing fee is currently $60. There is a $25 penalty for late filings. You will also have an annual business license renewal fee of $11 for a total annual state fee of $71.
The Washington Corporation: Formal Structure, Defined Governance, and Investor Appeal
A Corporation (C-Corp or S-Corp) functions as a distinct legal entity separate from its owners (shareholders). This structure is frequently chosen by businesses aiming for substantial growth, planning to raise external capital, or those that benefit from a more formalized governance framework. Like LLCs, Washington Corporations are subject to the state’s B&O tax.
Key Advantages of a Washington Corporation:
Strongest Liability Protection: Corporations provide the most robust shield for personal assets, completely separating the personal finances of shareholders from the corporation’s debts and legal obligations.
Capital Acquisition: The ability to issue shares of stock makes corporations highly attractive for raising capital from investors, including venture capitalists and public markets.
Credibility: The corporate structure can enhance a business’s perceived professionalism and stability, which can be advantageous in securing large contracts, partnerships, or loans.
Perpetual Existence: A corporation’s existence is independent of its owners, ensuring continuity even with changes in shareholder or management composition.
Well-Defined Legal Framework: Washington’s corporate laws provide a clear and established legal framework for corporate governance and operations.
No State Individual Income Tax (for shareholders): As with LLCs, individual shareholders are not subject to a state income tax on corporate distributions in Washington.
Washington Business Taxes Applicable to Corporations (as of July 2025 – Note on upcoming changes for 2025/2026/2027):
Business & Occupation (B&O) Tax: Corporations are subject to the same B&O tax classifications and rates as LLCs, as outlined above. This includes the existing rates, upcoming increases for service activities with over $5 million gross income (effective October 1, 2025), and the new 0.5% surcharge for businesses with over $250 million in Washington taxable income (effective January 1, 2026).
Sales and Use Tax: If your corporation sells tangible personal property or certain taxable services, it will collect and remit Washington sales or use tax (6.5% state, plus local add-ons up to 10.4%). The new taxable services (effective October 1, 2025) will also apply.
Capital Gains Excise Tax (Effective January 1, 2025): Corporations will also be subject to the 2.9% additional excise tax on Washington-sourced capital gains exceeding $1 million.
Unemployment Insurance (UI) Tax: If your corporation has employees, you will be required to register for and remit state UI taxes.
Local Business Licenses & Permits: Corporations, like LLCs, must obtain a state business license through the Master Business Application and secure any necessary local business licenses and permits.
Forming Your Washington Corporation: Key Steps (as of July 2025)
Name Selection: Choose a unique corporate name that includes “Corporation,” “Incorporated,” “Company,” “Limited,” or an abbreviation thereof (e.g., “Corp.,” “Inc.,” “Co.,” “Ltd.”). The name must be distinguishable from other entities on file with the Washington SOS. You can optionally reserve an available name for a $30 fee.
Appoint a Washington Registered Agent: A Washington corporation must appoint a registered agent with a physical street address in the state to receive legal and official documents.
Appoint Initial Directors and Officers: Washington requires at least one incorporator. The incorporator(s) will elect the initial directors (at least one director), and the directors will then appoint officers (President, Secretary, Treasurer, etc.). The Articles of Incorporation must list the names and addresses of each incorporator.
File Articles of Incorporation: This document is filed with the Washington Secretary of State. The filing fee is currently $200 (online) or $180 (by mail). The Articles of Incorporation must include:
The corporate name.
The registered agent’s name and registered office street address.
The names and addresses of each incorporator.
The total number of authorized shares (and if divided into classes, their designations).
The principal office street address and mailing address.
The purpose of the corporation (general purpose is usually acceptable).
The duration (if not perpetual).
The effective date (if a later date than filing, up to 90 days).
Adopt Corporate Bylaws: While not legally required to be filed with the state, every Washington corporation should adopt bylaws. These internal rules govern the corporation’s operations. They define the roles of shareholders, directors, and officers; outline meeting procedures; and detail how stock will be issued and transferred. They are crucial for internal governance and for maintaining the corporation’s separate legal existence.
Hold an Organizational Meeting: The initial directors should convene an organizational meeting to formally adopt bylaws, elect officers, authorize the issuance of shares of stock, and conduct other initial business. Minutes of this meeting should be kept.
Issue Stock: Shares of stock are issued to the initial shareholders as outlined in the Articles of Incorporation and bylaws.
Obtain an Employer Identification Number (EIN): An EIN is required for all federal tax purposes, opening business bank accounts, and hiring employees.
Apply for a Master Business License & State/Local Registrations: Corporations must also go through the Master Business Application process, obtaining a UBI number, registering for B&O tax, sales and use tax (if applicable), and employer accounts, as well as any necessary state and local licenses.
File Annual Report: All Washington corporations are required to file an Annual Report with the Washington Secretary of State. This report is due annually by the anniversary month of your corporation’s formation. The filing fee is currently $60. There is also an annual business license renewal fee of $11 for a total annual state fee of $71.
The Essential Modern Requirement: Beneficial Ownership Information (BOI) Reporting (Important Update!)
As of March 21, 2025, the Financial Crimes Enforcement Network (FinCEN) issued an interim final rule that removes the requirement for U.S. companies and U.S. persons to report beneficial ownership information (BOI) to FinCEN under the Corporate Transparency Act (CTA).
Therefore, if you are forming a domestic (U.S.) LLC or Corporation in Washington, you are currently EXEMPT from the FinCEN BOI reporting requirement.
However, it’s crucial to stay informed about any potential future changes or clarifications from FinCEN. This exemption applies specifically to U.S. entities. Foreign entities registering to do business in the U.S. may still have reporting obligations.
Making the Right Choice for Your Washington Enterprise
The optimal business structure for your venture in Washington depends on your specific objectives and operational preferences:
Choose a Washington LLC if you prioritize strong personal liability protection, desire operational flexibility with fewer internal formalities, and appreciate the absence of a state individual income tax. Be fully prepared for the Business & Occupation (B&O) tax on gross receipts, which is a significant factor in Washington.
Opt for a Washington Corporation if your plans involve raising significant external capital, require a highly formalized management structure, or if a traditional corporate framework (with its defined roles for shareholders, directors, and officers) is preferred by investors or industry standards. Like LLCs, corporations are subject to the B&O tax.
