That said, forming an LLC here isn't just about filing a single document. Washington has specific requirements: a Certificate of Formation, a registered agent with a physical in-state address, an Initial Report, a state Business License, and ongoing B&O tax obligations. Getting those details wrong costs time and money.
An LLC formation service handles the paperwork, coordinates the filings, and keeps you on track with compliance deadlines — so you can focus on actually running the business. Choosing the right one depends on what Washington specifically requires, not just which service has the lowest headline price.
Key Takeaways
- Washington's online LLC filing costs $200 ($180 base + $20 processing fee); mail filing is $180
- An annual report fee of $70 is due by the last day of your LLC's formation anniversary month each year
- Every Washington LLC must have a registered agent with a physical street address in the state — PO boxes don't qualify
- Washington has no corporate or personal income tax, but LLCs are subject to the Business & Occupation (B&O) gross receipts tax
- Top-rated services for 2026: ZenBusiness, Northwest Registered Agent, Bizee, Inc Authority, and LegalZoom
Why Form an LLC in Washington?
Washington's tax structure is one of the clearest advantages for new LLC owners. The state levies no corporate income tax and no personal income tax — but don't mistake that for a tax-free environment. LLCs operating here pay the Business & Occupation (B&O) tax, a gross-receipts tax applied regardless of profit. Rates range from 0.471% for retailers to 2.1% for service businesses with $5M+ in revenue (per the Washington Department of Revenue's October 2025 rate update).
The overall structure is still favorable, particularly for pass-through entities. Washington also has a dense entrepreneurial base: the latest SBA data shows over 25,000 new small business establishments opened in a single year, and the state consistently draws founders across industries.
That volume of new businesses is exactly why formation services have become a practical first step. A quality service files your Certificate of Formation with the Washington Secretary of State and handles the supporting work most founders overlook:
- Appointing a registered agent
- Obtaining an EIN from the IRS
- Drafting an operating agreement
- Tracking ongoing compliance deadlines
The services reviewed below were selected based on pricing, registered agent offerings, Washington-specific compliance support, and ease of use for 2026.
Best LLC Formation Services in Washington (2026)
ZenBusiness
ZenBusiness is one of the most widely used formation platforms, and its $0 Starter plan (plus the $200 Washington state filing fee) makes it accessible for first-time founders who need reliable filing without an upfront service charge.
What sets it apart is the post-formation experience. ZenBusiness includes a 100% accuracy guarantee on filings and a 60-day money-back window on plan charges (government fees excluded once submitted). Its in-account Velo assistant proactively flags compliance gaps and upcoming deadlines — useful for founders who don't want to track Washington's annual report cycle manually.
| Feature | Details |
|---|---|
| Starting Price | $0 + $200 Washington state filing fee |
| Registered Agent | $199/year add-on on Starter and Pro; included with Premium ($399/year) |
| Best For | First-time founders wanting filing accuracy and a compliance dashboard |
Northwest Registered Agent
Northwest is built around one thing: privacy. Its $39 formation package (plus $200 state fee) includes one full year of registered agent service, renewing at $125/year — one of the most competitive renewal rates among established providers.
Unlike many services that rely on third-party agent networks, Northwest owns and operates its registered agent infrastructure directly. Its Privacy by Default® approach keeps owner information off public filings wherever possible. The package also bundles a free domain, open-source website, business email, and phone line at no extra cost while agent service remains active.
| Feature | Details |
|---|---|
| Starting Price | $39 + $200 Washington state filing fee |
| Registered Agent | Included free for year one; $125/year renewal |
| Best For | Owners prioritizing privacy and a reliable owned registered agent address |
Bizee
Bizee (formerly Incfile) competes squarely on price. Its $0 Basic plan (plus $200 state fee) includes registered agent service free for the first year, renewing at $149/year — confirmed from Bizee's current official pricing.
The platform's modular add-on structure is its real differentiator. Founders can bolt on exactly what they need — operating agreement, EIN filing, S-corp election, virtual address, or annual report filing — without paying for bundled services they'll never use. Lifetime compliance alerts come standard on all plans.
| Feature | Details |
|---|---|
| Starting Price | $0 + $200 Washington state filing fee |
| Registered Agent | Free for year one; $149/year renewal |
| Best For | Budget-conscious founders who want a customized, modular service plan |
Inc Authority
Inc Authority offers one of the most feature-rich free formation packages available. Its $0 plan (plus $200 state fee) bundles a free EIN and one year of registered agent service — features that most services charge separately for. The checkout process clearly separates Washington's state filing fee from Inc Authority's own $0 charge, which avoids the hidden-cost confusion common on competing platforms.
The plan also includes a tax consultation referral. One gap worth noting: Inc Authority doesn't offer an ongoing compliance dashboard post-formation, so founders tracking annual report deadlines will need to manage that independently.
| Feature | Details |
|---|---|
| Starting Price | $0 + $200 Washington state filing fee |
| Registered Agent | Included free for year one; $249/year thereafter |
| Best For | Founders seeking maximum features at zero upfront cost |
LegalZoom
LegalZoom is the most recognized name in LLC formation and brings something the others don't: direct access to licensed attorneys. Its $0 Basic plan (plus $200 state fee) includes a small business specialist consultation.
Pro ($249) and Premium ($299) plans add a 150+ attorney-drafted legal document library, EIN assistance, and 30 days of the Business Attorney Plan with unlimited 30-minute consultations on new matters.
The 60-day money-back guarantee applies to filed products before agency submission. Registered agent service is not included in any plan — it's a separate $249/year add-on.
| Feature | Details |
|---|---|
| Starting Price | $0 + $200 Washington state filing fee |
| Registered Agent | Not included; $249/year add-on |
| Best For | Business owners who anticipate ongoing legal needs beyond formation |
Washington LLC Formation: Key Requirements
Filing Costs and Timelines
| Requirement | Cost | Notes |
|---|---|---|
| Certificate of Formation (online) | $200 | $180 base + $20 online processing fee (WAC 434-112-075) |
| Certificate of Formation (mail) | $180 | No processing fee; worked in receipt order |
| Initial Report | Free with formation; $10 if filed separately | Due within 120 days of formation |
| Business License | $50 | Required from the WA Department of Revenue |
| Annual Report | $70/year | Due by last day of LLC's anniversary month |
| Expedited processing | $100 | Generally within three working days |
| Same-day service | $150 | Available from the Secretary of State |
Realistic first-year cost: If you file the Initial Report with formation, you're looking at approximately $320–$330 online before any service fees, factoring in the filing, business license, and first annual report.
Registered Agent Rules
Washington law requires every LLC to maintain a registered agent at a physical street address within the state. PO boxes, private mailboxes, and virtual office addresses do not satisfy this requirement under RCW 23.95.400–.460. The agent must be available during business hours to receive legal documents.
Using a professional registered agent service has a practical benefit beyond compliance: it keeps your personal address off Washington's public business registry.
Washington's B&O Tax
Washington's Business & Occupation tax is applied to gross receipts — not net profit. That means standard business deductions don't reduce your taxable base. Current rates (effective October 1, 2025):
- Retailing: 0.471%
- Wholesaling: 0.484%
- Service businesses under $1M revenue: 1.5%
- Service businesses $1M–$4.99M: 1.75%
- Service businesses $5M+: 2.1%
Small businesses may qualify for a B&O tax credit that reduces liability based on monthly tax amounts. Service businesses can receive up to $160/month in credits before the phase-out threshold kicks in. If your LLC operates across multiple states, tracking these obligations alongside other jurisdictions adds complexity — professional accounting support helps keep you on the right side of each state's rules.
How We Chose the Best LLC Formation Services
Evaluation Framework
Washington-specific fit was a core part of the assessment — not just general service quality. The key questions were:
- Does the service's registered agent meet Washington's physical-address requirement?
- How well does its compliance tooling handle the state's annual report renewal cycle?
- Is pricing transparent for the full cost, including state fees?
Criteria Weighted in Selection
- Starting price and total first-year value
- Registered agent inclusion and renewal cost
- EIN assistance availability
- Operating agreement quality
- Turnaround times and expedite options
- Dashboard functionality and compliance alerts
- Customer support quality and money-back guarantees
Common Mistakes to Avoid
The headline formation price is easy to anchor on — but it rarely tells the full story. A $0 plan with a $249/year registered agent renewal (LegalZoom, Inc Authority) can cost significantly more over three years than a $39 plan with a $125/year renewal (Northwest). Three cost traps catch most first-time founders:
- Registered agent renewal costs, not included in the formation quote, often double the real first-year spend
- Not all agents own their own addresses; many lease from third parties, which affects reliability
- Post-formation compliance tools matter more than formation speed if you need ongoing deadline tracking
Conclusion
The right LLC formation service for a Washington business comes down to what you need beyond the initial filing:
- Northwest Registered Agent — best for privacy-first founders who want an owned, in-house agent at a competitive renewal rate
- Inc Authority — best for maximum value with zero upfront cost, including a bundled EIN
- LegalZoom — best for founders who expect to need attorney access and a legal document library post-formation
- ZenBusiness — best for founders who want an ongoing compliance dashboard and proactive deadline alerts
- Bizee — best for budget-conscious founders who want to build a lean, modular service stack
Formation is step one. Staying compliant — filing annual reports, managing B&O tax obligations, renewing your business license — requires consistent attention year after year.

Frequently Asked Questions
How much does it cost to create an LLC in Washington?
The Certificate of Formation costs $200 online or $180 by mail. Add the $50 Business License and $70 first annual report, and you're looking at roughly $320–$330 in mandatory state costs for year one. The Initial Report ($10) is free if filed with formation but costs $10 when filed separately.
Do I need a registered agent for my Washington LLC?
Yes. Washington law requires every LLC to maintain a registered agent with a physical street address in the state. PO boxes and virtual offices don't qualify. Using a professional service keeps your personal address off public records.
How long does it take to form an LLC in Washington?
Standard online filings are processed in receipt order, with no officially published turnaround estimate. Expedited processing ($100) is generally completed within three working days; same-day service is available for $150.
What is the Washington B&O tax and does it apply to my LLC?
The B&O tax is a gross-receipts tax applied to Washington LLCs regardless of profit — operating expenses cannot be deducted from the taxable base. Rates range from 0.471% for retailers to 2.1% for large service businesses. Notably, Washington has no corporate or personal income tax.
Do I need an operating agreement for my Washington LLC?
Washington does not require an operating agreement to be filed with the state. Still, having one is strongly recommended — it protects the LLC's liability shield, defines ownership terms, and prevents disputes among members.
Can a non-US resident form an LLC in Washington?
Yes. Washington statutes (RCW 25.15.071) impose no citizenship or residency requirement on LLC organizers. Non-US residents will need a registered agent with a physical Washington address, plus additional help obtaining a US EIN and opening a business bank account.
