Washington State has quietly become one of the more attractive destinations for new business owners — particularly for tech entrepreneurs, e-commerce operators, consultants, and service providers who benefit from the state’s complete absence of personal income tax. If you’re ready to formalize your business and separate your personal assets from your professional liability, knowing how to start an LLC in Washington is the first practical step.
The core process is straightforward: file a Certificate of Formation with the Washington Secretary of State, pay a $200 state fee, and maintain a registered agent with a Washington address. Most people can complete the filing in under an hour. ZenBusiness — our top-rated formation service in 2026 — handles the full process starting at $0 plus the state fee, with registered agent service included free for the first year. That’s a better deal than doing it yourself and then paying $125/year separately for agent coverage.
This guide walks through every step of Washington LLC formation, including naming rules, filing procedures, the state’s unique Business & Occupation tax, ongoing compliance obligations, and an honest comparison of the services that can do the heavy lifting for you.
Why Washington Is Worth a Closer Look for Your LLC
As of 2026, Washington remains one of only nine states with no personal state income tax. For LLC owners, that means pass-through profits from your business won’t be taxed at the state level the way they would in California (up to 13.3%), Oregon (up to 9.9%), or even nearby Idaho (up to 5.8%).
Washington also has no franchise tax on LLCs — no annual minimum payment to the state just for existing, unlike California’s $800 minimum annual franchise tax or Texas’s franchise tax on revenue. You pay a $71 annual report fee, and that’s roughly it on the state side.
The tradeoff is Washington’s Business & Occupation (B&O) tax, a gross receipts tax that applies to nearly all businesses regardless of profitability. We’ll cover it in detail below — it’s manageable once you understand how it works, but it surprises business owners who assume “no income tax” means “no business taxes.”
How to Start an LLC in Washington: Step-by-Step
Step 1: Choose a Name for Your Washington LLC
Your LLC name must meet these requirements:
- Include “Limited Liability Company,” “LLC,” or “L.L.C.”
- Be distinguishable from existing registered business names in Washington
- Not use words that imply a government affiliation (e.g., “FBI,” “Treasury,” “State Department”)
- Not use restricted professional words (“Bank,” “Attorney,” “Doctor”) without the relevant license
Search the Washington Secretary of State’s Corporations and Charities Filing System (CCFS) for free to check name availability before you commit. If you find a name you want but aren’t ready to file yet, you can reserve it for $30 for up to 180 days by submitting a Name Reservation Request.
A note on strategy: check domain availability at the same time. There’s no point forming an LLC with a name that has no viable web presence options — a lesson I’ve seen entrepreneurs learn the hard way after already filing.
Step 2: Appoint a Registered Agent
Every Washington LLC must designate a registered agent — a person or entity with a physical street address in Washington (P.O. boxes don’t qualify) who is available during regular business hours to accept legal notices, lawsuits, and official government correspondence on the LLC’s behalf.
You can act as your own registered agent, and many solo founders do. The practical downside: your personal or business address becomes part of the public record, and if you’re ever served a lawsuit when you’re not at the address on file, you could miss the notice entirely — which courts can treat as valid service regardless.
Professional registered agent services typically run $49–$299/year. ZenBusiness includes it free for year one (then $99/year). Northwest Registered Agent charges $125/year and includes strong privacy protections by default, making it a good option if keeping your personal address off public filings is a priority. Unlike ZenBusiness, Northwest doesn’t bundle it into a free formation tier — their base package starts at $39 plus state fees.
Step 3: File Your Certificate of Formation
The Certificate of Formation is the official document that legally creates your Washington LLC. File it with the Secretary of State via the CCFS portal — or by mail if you prefer paper.
2026 Washington LLC filing fees:
| Filing Method | Fee |
|---|---|
| Online (CCFS portal) | $200 |
| Paper (mail) | $230 |
| 2-business-day expedited | $50 additional |
| Same-day expedited | $100 additional |
Your Certificate must include: the LLC’s name, the registered agent’s name and address, whether the LLC is member-managed or manager-managed, the organizer’s name and address, and the effective date (can be immediate or up to 90 days in the future).
Standard online processing runs approximately 5–7 business days, though approvals often come back in 2–3 days during lighter filing periods. Once approved, Washington issues your LLC a Unified Business Identifier (UBI) number — your state-level business ID used for all subsequent filings and tax registrations.
Step 4: Draft an Operating Agreement
Washington does not legally require LLCs to have an operating agreement, but this is one area where the “technically optional” framing is genuinely misleading. Without a written operating agreement, your LLC’s governance defaults to Washington’s catch-all LLC statutes — which are generic and may not reflect how you actually intend to run your business.
A solid operating agreement covers:
- Ownership percentages and each member’s capital contributions
- How profits and losses are distributed
- Voting rights and decision-making authority
- Procedures for adding or removing members
- What happens if the LLC dissolves
For single-member LLCs, the operating agreement is particularly valuable as evidence that your LLC is a genuine, separate legal entity — not just a shell — if a court or the IRS ever scrutinizes the business. I’ve seen too many solo business owners skip this step only to face complications when they try to open a business bank account or bring on a business partner years later.
ZenBusiness includes an operating agreement template with its Starter plan. LegalZoom also provides a template, but charges extra if you want attorney review of the document — a distinction worth noting if your business has any complexity.
Step 5: Get a Federal EIN from the IRS
An Employer Identification Number (EIN) is your LLC’s federal tax identification number — functionally the business equivalent of a Social Security number. You’ll need one to open a business bank account, hire employees, file federal tax returns as a multi-member LLC, and register for various licenses and permits.
Single-member LLCs with no employees can technically use their personal SSN for some purposes, but getting an EIN anyway is smart practice. It simplifies banking, protects your SSN from exposure, and costs nothing.
Apply directly through the IRS EIN online application — free, and your EIN is issued immediately upon completion. Most formation services offer EIN obtainment as a paid add-on ($50–$70), so doing it yourself is an easy $50+ savings.
Step 6: Register with the Washington Department of Revenue
If your LLC will collect sales tax, employ workers, or have taxable B&O gross receipts (which covers nearly every Washington business), you’ll need to register with the Washington State Department of Revenue. This is free and can be done online.
Registration produces a Master Business License, which also authorizes you to operate under a trade name (DBA) in Washington if needed. This is a separate step from your Secretary of State filing and is frequently overlooked by new business owners — don’t skip it, or you may face back taxes and penalties later.
Step 7: Open a Dedicated Business Bank Account
Once you have your EIN and formation documents in hand, open a dedicated business checking account before you conduct any transactions. This is non-negotiable for maintaining the liability shield your LLC provides — commingling personal and business funds is one of the primary ways courts “pierce the corporate veil” and hold members personally liable for business debts.
Most major banks require your EIN, formation documents, and operating agreement to open a business account. Online business banks like Mercury or Relay often work well for newer LLCs and carry lower fees than traditional banks for accounts with modest starting balances.

Washington LLC Taxes: Understanding the B&O Tax
Washington’s lack of personal income tax is the headline, but the Business & Occupation (B&O) tax is what every Washington LLC owner needs to understand before they open for business.
Unlike a corporate income tax or personal income tax, the B&O tax is a gross receipts tax — meaning it’s calculated on total revenue, not on profit. If your service business grosses $200,000 but your expenses consume $190,000, you still owe B&O tax on the full $200,000. This is Washington’s unique trade-off for having no income tax.
Key B&O tax rates (2026 approximate rates — confirm current rates with the Washington DOR):
| Business Type | Approximate B&O Rate |
|---|---|
| Retailing | 0.471% of gross revenue |
| Wholesaling | 0.484% of gross revenue |
| Manufacturing | 0.484% of gross revenue |
| Service and other activities | ~1.5% of gross revenue |
For a service-based LLC generating $150,000 annually, that’s roughly $2,250 in B&O tax — manageable, but it affects pricing decisions, particularly for low-margin businesses.
The small business B&O tax credit is available to businesses with annual gross receipts below $55,000, providing up to $125/month in credit against B&O liability. For micro-businesses and early-stage LLCs, this can effectively zero out the B&O tax obligation in the early years.
Washington also imposes a Retail Sales Tax (6.5% state rate plus local additions that typically bring the combined rate to 9–11% depending on city) if your LLC sells taxable goods or services to Washington customers.
At the federal level, a single-member Washington LLC is treated as a disregarded entity by default — you report income on Schedule C of your personal return. Multi-member LLCs default to partnership taxation with a Form 1065. Once your net income reaches roughly $60,000–$80,000 annually, it’s worth evaluating an S-Corp election to reduce self-employment tax exposure. Our LLC vs S-Corp guide walks through when that switch typically makes sense.
Formation Service vs. DIY: Which Makes More Sense?
Filing the Certificate of Formation yourself through Washington’s CCFS portal is genuinely feasible — the portal is well-designed, and the form itself isn’t complicated. You’ll pay the same $200 state fee either way.
In my experience, the bigger risk isn’t making a filing error — it’s the steps that come after. New LLC owners routinely forget to get an EIN before trying to open a bank account, skip the operating agreement because it feels like paperwork, or never register with the Department of Revenue because nobody told them they needed to. A formation service provides a structured checklist that walks you through the full process, not just the filing.
Here’s how the major services stack up for Washington LLC formation in 2026:
| Service | Base Price (+ $200 state fee) | Registered Agent Included | Operating Agreement | Best For |
|---|---|---|---|---|
| ZenBusiness | $0 | Free Year 1, $99/yr after | Yes | Overall best value |
| LegalZoom | $0 | $249/yr (add-on) | Yes | Brand name + legal access |
| Tailor Brands | $0 | Paid add-on | Yes | Branding + formation bundle |
| Inc Authority | $0 | Free Year 1 | Yes | Free tier with optional upgrades |
| Northwest Registered Agent | $39 | $125/yr (included) | Yes | Privacy-focused businesses |
| Bizee | $0 | Free Year 1 | Yes | Basic budget formation |
| LLC Attorney | Custom | Varies | Attorney-reviewed | Complex high-risk formations |
ZenBusiness is our primary recommendation for most Washington LLC formations. Their Starter plan includes registered agent service free for year one — a benefit worth $99–$249 depending on what you’d pay elsewhere. LegalZoom charges $249/year for registered agent service as a separate line item, meaning the “free” formation tier gets expensive fast. For a detailed side-by-side, see our ZenBusiness vs LegalZoom comparison.

Washington LLC Ongoing Compliance Requirements
Washington LLC formation isn’t a one-time task — staying in good standing requires annual attention to a few recurring obligations.
Annual Report ($71/year) Washington requires all LLCs to file an annual report with the Secretary of State by the last day of your LLC’s anniversary month each year. The fee is $71 for online filing. Miss it by a day and you’ll face a $25 late penalty; ignore it long enough and the state can administratively dissolve your LLC. Set a calendar reminder — the Secretary of State sends email reminders, but they can land in spam.
B&O Tax Filing B&O tax is reported to the Washington Department of Revenue on a monthly, quarterly, or annual schedule based on your revenue volume. Most new small businesses are assigned quarterly filing. Even if your B&O liability is zero (thanks to the small business credit), you’re still required to file a return.
Master Business License Renewal ($19/year) Your Washington Master Business License renews annually at a base fee of $19, though the total can vary if you’ve added endorsements for specific business activities.
Federal BOI Reporting Under the Corporate Transparency Act, most LLCs are required to file a Beneficial Ownership Information (BOI) report with FinCEN. This is a federal requirement — separate from all Washington state filings. Our BOI report guide covers current deadlines, exemptions, and how to file.
Frequently Asked Questions About Washington LLCs
How much does it cost to start an LLC in Washington in 2026?
The minimum is $200 — the state filing fee for the Certificate of Formation. Add a registered agent service and you’re looking at $200–$325 for year one, depending on provider. Using ZenBusiness keeps year-one costs at the $200 state fee since registered agent service is included free. The recurring annual report fee is $71/year.
How long does it take to form an LLC in Washington?
Standard online filings through the CCFS portal typically take 5–7 business days. Expedited 2-business-day processing is available for an additional $50, and same-day processing for $100 extra. Washington does not offer instant approval — even the fastest option requires at least one full business day.
Does Washington require a registered agent for an LLC?
Yes. Every Washington LLC must maintain a registered agent with a physical street address in Washington who is available during regular business hours. You can serve as your own registered agent, but you’ll need to list your personal address publicly and be reliably present there. Most business owners find a professional service worth the $99–$125/year cost.
Do I need an operating agreement for my Washington LLC?
Washington law doesn’t require one, but you should have one regardless. Without it, your LLC’s governance defaults to Washington’s generic statutes. For multi-member LLCs, a missing operating agreement is a common trigger for member disputes. For single-member LLCs, it’s important evidence that your LLC is a genuine separate legal entity — which matters for both banking and liability protection.
What is the Washington B&O tax and how does it affect my LLC?
The Business & Occupation (B&O) tax is Washington’s gross receipts tax applied to business revenue regardless of profitability. Service businesses pay approximately 1.5% of gross revenue; retailers pay around 0.471%. Small businesses with under $55,000 in gross annual receipts may qualify for a B&O tax credit that eliminates most of their liability. File B&O returns with the Washington Department of Revenue on a monthly, quarterly, or annual schedule.
Can I be my own registered agent in Washington?
Yes, if you have a physical Washington street address and can be reliably reached there during business hours. The tradeoffs are that your address becomes public record and you risk missing legal documents if you’re unavailable. For most business owners, a professional registered agent service at $99–$125/year is the more practical choice.
Does Washington require an LLC to publish a formation notice in a newspaper?
No. Washington does not require any newspaper publication after forming an LLC. This distinguishes Washington from states like Arizona and New York, where publication requirements can add $300–$1,500+ to your formation costs.
What ongoing filings does a Washington LLC need to make?
Annual requirements include: a $71 annual report to the Secretary of State (due in your anniversary month), B&O tax returns to the Department of Revenue, and a $19 Master Business License renewal. Federal BOI reporting to FinCEN is also required for most LLCs under the Corporate Transparency Act.
The Bottom Line: Starting a Washington LLC in 2026
Washington is a strong state for LLC formation in 2026 — no personal income tax, no franchise tax, a reasonable $200 filing fee, and a state government that has invested in making online filing genuinely usable. The B&O tax is the most important variable to plan around, particularly for service businesses, but it’s predictable and manageable once you understand the rate structure.
The practical playbook for how to start an LLC in Washington the right way: file online, lock in a professional registered agent from day one, draft your operating agreement before you sign your first client contract, and register with the Department of Revenue before you invoice anyone.
ZenBusiness remains the strongest all-around choice for most Washington business owners — $0 formation fee plus the $200 state fee, registered agent included for year one, and an operating agreement template built in.
