To start an LLC in Washington in 2026, file a Certificate of Formation with the Secretary of State ($180 by mail, $200 online), appoint a registered agent with a physical Washington street address, and file your initial report within 120 days of formation. Most LLCs also register for a Washington business license (about $50, check current pricing). The whole process takes roughly 5 business days online, and a non-US founder can do every step without a Social Security number or US residency.
This guide covers all seven steps with real fees, real timelines, and the B&O tax that surprises founders who expected “no income tax” to mean “no taxes.”

Step 1: Choose and Check Your LLC Name
Your LLC’s legal name must contain one of these designators: “Limited Liability Company,” “Limited Liability Co.,” “LLC,” or “L.L.C.” (RCW 25.15). Beyond that, Washington requires your name to be distinguishable from every other entity on file with the Secretary of State. Minor tweaks like adding “the” or changing punctuation do not always clear that bar.
Check your proposed name in the Secretary of State’s Corporations and Charities Filing System (CCFS) at ccfs.sos.wa.gov before you pay anything, searching without the LLC designator to catch the widest range of conflicts. Washington also restricts words implying a different entity type (“Corporation,” “Inc.,” “Bank,” “University”) without regulator authorization.
Not ready to file yet? Reserve an available name for 180 days for $30 through CCFS. If you are ready, skip the reservation; approval of the Certificate of Formation locks the name automatically.
Step 2: Appoint a Registered Agent
Washington requires every LLC to maintain a registered agent under RCW 23.95. The agent must have a physical street address in Washington, be available there during normal business hours to accept service of process and official notices, and give consent to the appointment. A PO box alone is not accepted. The agent’s name, address, and an email address go directly on your formation filing, and all of it becomes public record.
You can serve as your own agent if you live in Washington and keep regular hours there. If you travel or do not want legal papers arriving at your door, a professional service makes more sense. For non-US founders this step is mandatory in practice: you cannot serve as your own Washington agent from abroad.
Form your Washington LLC with Registered Agents Inc covers the registered agent appointment, with one year of free registered agent service included in the $100 + state fee bundle. Read Do I Need a Registered Agent? for the full breakdown.
Step 3: File the Certificate of Formation
The Certificate of Formation is Washington’s formation document, filed with the Secretary of State’s Corporations and Charities Division. Your filing needs:
- The LLC name and address
- The registered agent’s name, address, and email
- Whether the LLC is member-managed or manager-managed
- The nature of the business
- The effective date (can be the filing date or a future date)
- A return email and address for filing correspondence
File online through CCFS for $200 total ($180 filing fee plus a $20 online processing fee) or by mail for $180 flat. Online filings take about 5 business days; mail takes roughly 15. Expedited service is $100 extra for roughly 3 business days, and in-person same-day service in Olympia or Cheney costs $150.
Once accepted, the state assigns your LLC a Unified Business Identifier (UBI) number. Save it. You will use it for every interaction with Washington agencies afterward.
Step 4: Create an Operating Agreement
Washington does not require you to file an operating agreement, but you should have one anyway. This internal document spells out who owns the LLC, how profits are split, how decisions are made, and what happens if a member leaves. Banks ask for it when you open an account. If you ever face a dispute, it is the document that settles it.
For a single-member LLC it is short: you own 100% and make all decisions. For multi-member LLCs, specify contributions and voting rights. Keep the signed agreement with your company records. See our LLC Operating Agreement Guide for a walkthrough of what to include.
Step 5: Get an EIN from the IRS
An Employer Identification Number (EIN) is the federal tax ID for your LLC. You need it to open a US business bank account, file federal tax returns, and hire employees. It is free from the IRS, and you should never pay a service for it.
US founders with a Social Security number apply online at IRS.gov and get the number instantly. Non-US founders fax or mail Form SS-4 to the IRS instead, which takes roughly 4 to 8 weeks. Write “Foreign” in the SSN field and list the LLC’s foreign owner as the responsible party. Full walkthrough: How to Get an EIN as a Foreigner.
Step 6: Open a US Bank Account
Bring your approved Certificate of Formation, EIN confirmation letter, and operating agreement to the bank. Most US banks ask for a photo ID and an initial deposit. For non-US founders abroad, traditional accounts are the hardest step since many banks require a branch visit; fintech options like Wise or Mercury accept non-resident owners with their own documentation requirements.
Open the account in the LLC’s name only, and never mix business and personal funds. Commingling is one of the fastest ways to lose the liability protection the LLC exists for.
Step 7: Get Your UBI Number and Washington Business License
Forming the LLC is only half the state paperwork. Most businesses operating in Washington must also register with the Department of Revenue through a Business License Application costing about $50 at the base level (check current pricing; endorsements can raise it), processed in roughly 10 business days.
File the Certificate of Formation first, then the Business License Application. Filing out of order can cause the state to assign two separate UBI numbers, creating a tax-reporting mess.
A Washington LLC run from abroad still generally needs the business license if it has nexus in Washington. The registered agent address alone does not create tax nexus, but a Washington-organized LLC with Washington-source income usually has it. When in doubt, file the license.
Starting a Washington LLC as a Non-US Founder
Washington imposes no citizenship or residency requirement on LLC members or managers, so founders from Pakistan, India, the UAE, or anywhere else can own a Washington LLC outright. A few things work differently for you:
No SSN needed. Form the LLC, get an EIN by faxing Form SS-4, and open a fintech bank account with just your passport and foreign address. Your foreign address goes on the filing; only the registered agent address must be in Washington.
Federal taxes still apply. A foreign-owned single-member LLC is a disregarded entity for US tax purposes, which means you file Form 5472 (information return on transactions with the foreign owner) plus a pro-forma Form 1120 every year, due April 15. Penalties for a missing Form 5472 start at $25,000 per year, so this is not optional. If your LLC is taxed as a corporation or has US-source income, additional federal obligations apply.
Washington taxes still apply. No personal or corporate income tax, but the B&O tax hits your LLC’s gross receipts with no deductions for costs, whether you live in Seattle or Karachi. Main rates as of October 2026: retailing 0.471%, wholesaling and manufacturing 0.484%, and services 1.5% on the first $1 million, 1.75% up to $5 million, and 2.1% above that. A small business B&O tax credit phases out as receipts grow. Because the tax hits gross receipts, you can owe B&O tax in a year your business lost money.
Register with the Department of Revenue early. Do not wait until revenue gets messy. The Business License Application in Step 7 is also your DOR registration, so you handle it at formation.
Washington vs Wyoming for a Non-US Founder
This is the comparison most non-US founders actually face. Both states have no income tax, but the similarities end there.
Wyoming usually wins on cost and simplicity: $100 formation, a $60 annual license tax, no B&O tax on gross receipts, and member names kept off the public record. For a digital business serving global customers, Wyoming is almost always cheaper and quieter.
Washington wins when your business genuinely operates there: a Seattle presence, Washington employees, or Washington inventory. If you do enough business in Washington to have nexus anyway, registering there as your home state is simpler than forming in Wyoming and then registering as a foreign LLC in Washington (which costs $180 anyway).
The trap is forming in Wyoming to dodge Washington taxes while actually operating there. Washington’s $100,000 economic nexus threshold means that level of Washington-source receipts pulls you into Washington tax obligations regardless of where the LLC was formed.

Washington LLC Ongoing Compliance
Forming the LLC is the easy part. Staying compliant is what keeps it alive:
- Initial report: due within 120 days of formation. Free if you filed it with the Certificate of Formation, $10 if you file it separately.
- Annual report: $70 yearly, due by the last day of your anniversary month. Miss it and a $25 late fee applies; persistent noncompliance leads to administrative dissolution. File online through CCFS up to 180 days early.
- Business license renewal: your Washington business license renews with the Department of Revenue, plus any city endorsements (Seattle has its own B&O tax and licensing, separate from the state’s).
- B&O tax filings: the DOR assigns a filing frequency (monthly, quarterly, or annual) based on your liability. File even in zero-tax periods.
- Form 5472 + pro-forma 1120: foreign-owned single-member LLCs file these with the IRS every year by April 15.
- Keep a registered agent: if your agent resigns or the address goes stale, replace them immediately. A gap can mean missed lawsuits and penalties.

Frequently Asked Questions
How much does it cost to start an LLC in Washington?
The Certificate of Formation costs $180 by mail or $200 online, plus about $50 for the required Washington business license application (check current pricing). Budget $230 to $280 in state fees for a self-filed LLC in year one, plus $70 per year for the annual report and whatever you pay for a registered agent service.
How long does it take to form an LLC in Washington?
Online filings through CCFS take about 5 business days, and mail filings take roughly 15. Expedited service ($100 extra) cuts it to about 3 business days, and in-person same-day service in Olympia or Cheney costs $150. The business license application with the Department of Revenue takes about 10 additional business days.
Does Washington require an initial report for LLCs?
Yes. Every new Washington LLC must file an initial report within 120 days of formation under RCW 23.95.255. It is free when submitted together with your Certificate of Formation and $10 if filed separately. Do not confuse it with the annual report, which is a separate $70 yearly filing due by your anniversary month.
Can a non-US citizen start an LLC in Washington?
Yes. Washington has no citizenship or residency requirement for LLC members or managers. You do not need a Social Security number or a US address to own the LLC, though you do need a registered agent with a physical Washington street address. You will still owe federal filings (Form 5472 for single-member LLCs) and Washington’s B&O tax on gross receipts.
Does a Washington LLC need a business license?
Almost certainly yes. Most LLCs operating in Washington must file a Business License Application with the Department of Revenue, which costs about $50 at the base level and ties your LLC to its UBI number. File it after the Certificate of Formation is accepted to avoid getting duplicate UBI numbers.
Is Washington good for an LLC if I live abroad?
It depends on your business. Washington has no personal or corporate income tax, which sounds ideal, but the B&O tax on gross receipts (1.5% for most services) means you pay tax on revenue before expenses. If you do not physically operate in Washington, Wyoming is usually cheaper and simpler. If your business has Washington nexus anyway, forming there is the straightforward choice.

Conclusion
Starting an LLC in Washington is a two-agency process: the Secretary of State for formation, the Department of Revenue for the business license and tax registration. As of October 2026: $180 by mail or $200 online to file, a $10-or-free initial report within 120 days, a $70 annual report every year, and a gross-receipts B&O tax instead of income tax. Non-US founders need no SSN or residency, but the EIN-by-fax process and annual Form 5472 filing must be on your calendar from day one.
The simplest way to handle it is to let a formation service manage the paperwork. Form your Washington LLC with Registered Agents Inc for $100 + state fee, which includes the Certificate of Formation filing, a domain name, a website, and one year of free registered agent service. Check current pricing on their site, then use the saved time to focus on the business itself.
