Cost Calculator

Forming an LLC in Washington requires a state filing fee of $200. Combined with a registered agent ($150/year estimated), annual report fees of $60, your first-year total comes to approximately $410.

The standard processing time for Washington LLC filings is 2 business days, with expedited processing available for $50. Online filing through the Washington Secretary of State is available and typically processes faster than paper filings.

Washington LLCs are governed by RCW § 25.15.006. Washington has no state income tax, making it competitive for LLCs.

Annual reports are due by the end of the anniversary month. The state has a $60 annual fee and no minimum franchise tax.

Washington enacted a Series LLC statute (RCW § 25.15.006) — Washington's LLC Act includes series LLC provisions. Washington's charging order is the exclusive remedy for LLC creditors.

Professionals (attorneys, CPAs, architects, engineers, physicians) in Washington must form a Professional LLC (PLLC) under RCW Chapter 18.100. Washington Department of Commerce and WA SBDC provide resources.

Washington has no state income tax — a major competitive advantage for LLC member distributions. Washington's Business and Occupation (B&O) tax is based on gross receipts (not income), ranging from 0.138% to 1.5% depending on business classification — a cost that catches many new LLC owners off guard.

Washington's tech ecosystem (Amazon, Microsoft, Boeing) drives significant LLC formation in software, aerospace, e-commerce, and clean energy.

After initial formation, Washington LLCs face ongoing compliance costs. The annual report fee is $60, which must be filed to keep your LLC in good standing.

A registered agent — required by Washington law — typically costs $100–$300/year depending on the service provider.

Expect annual ongoing costs of approximately $210 for a Washington LLC (registered agent + annual fees). This does not include business licenses, professional fees, or taxes.

Washington may also require local business licenses depending on your municipality and business type. Many cities require a business license ranging from $25 to $500/year.

Check with your county clerk's office for local requirements beyond the state-level LLC registration.

Many entrepreneurs consider forming their LLC in a different state — most commonly Delaware, Wyoming, or Nevada — to take advantage of favorable laws. However, if you operate primarily in Washington, you will likely still need to register as a foreign LLC in Washington, paying both that state's fees AND Washington's foreign registration fee, making domestic registration typically more cost-effective.

Delaware, Wyoming, and Nevada are popular for their advanced LLC laws, privacy protections, and tax benefits. However, for a small business operating solely in Washington, forming domestically is usually simpler and more cost-effective.

An attorney or business formation service can help you decide the optimal formation state for your specific situation. Factors include where you'll operate, the nature of your assets, investor requirements, and long-term exit plans.

While Washington does not legally require an LLC operating agreement, it is strongly recommended for all Washington LLCs. An operating agreement defines member rights, profit distribution, voting procedures, and what happens if a member leaves or the LLC is dissolved.

Without an operating agreement, Washington's default LLC rules under RCW § 25.15.006 will govern your business, which may not align with your intentions. For single-member LLCs, an operating agreement helps establish the legal separation between you and the business — important for liability protection.

Operating agreements drafted by an attorney in Washington typically cost $500–$1,500 for simple agreements or $1,500–$3,000 for complex multi-member structures. Online templates are available but may miss state-specific provisions.

Washington requires every LLC to maintain a registered agent — an individual or company with a physical address in Washington who can accept legal documents during business hours. You can serve as your own registered agent, use an owner or employee at a Washington address, or hire a professional registered agent service.

Professional registered agent services in Washington typically cost $100–$300/year and offer advantages including privacy (your home address isn't public record), reliability (they never miss service of process), and compliance reminders for annual report deadlines.

Failing to maintain a registered agent in Washington can result in administrative dissolution of your LLC. If you move or change addresses, update your registered agent information with the Washington Secretary of State promptly.

By default, a single-member LLC in Washington is taxed as a sole proprietorship, and a multi-member LLC is taxed as a partnership — both pass-through entities where profits are reported on the owners' personal tax returns. Washington LLCs can also elect S-Corp or C-Corp tax treatment for potential tax savings.

Washington may impose its own state income tax on LLC profits. Depending on your revenue and structure, an S-Corp election can sometimes reduce self-employment taxes, though this adds payroll complexity.

Consult a CPA familiar with Washington tax law before making tax elections.

Washington LLCs may also be subject to state sales tax if selling taxable products or services. Register for a sales tax permit with Washington's Department of Revenue and file returns on the schedule required for your revenue level.
