You’ve decided to start your business — congratulations! 🎉
Now comes the practical part: officially registering your Washington LLC. The filing process may look complicated at first, but it’s actually very manageable once you know what to expect.
In this guide, I’ll walk you through how to register your LLC in Washington State, the difference between online and paper filing, what information you’ll need, and how long it takes to become official.
🧾 1. How do I register an LLC in Washington State?
To form an LLC, you’ll file a Certificate of Formation with the Washington Secretary of State (Corporations & Charities Division).
You can complete the filing:
- Online through the state’s Corporations and Charities Filing System (CCFS). I highly recommend doing this online as you will need to have an account set up for doing reports annually at the very least.
- By mail using paper forms
Once approved, you’ll receive your Certificate of Formation and a Unified Business Identifier (UBI) — your business’s unique number used across all state agencies.
💻 2. LLC Filing: Should You File Them Online or Mail Them In?
| Filing Method | Processing Time | Cost | Pros | Cons |
| Online | Usually 2–5 business days | $200 | Fast, convenient, confirmation email, easy to track | Requires online account |
| By Mail | 2–3 weeks (plus mail time) | $180 | Slightly cheaper | Slower, no online tracking |
💡 Tip: If you need your LLC formed quickly — for a new contract, client, or business bank account — file online.
📍 3. How do I file a Certificate of Formation in Washington?
You’ll file directly with the Washington Secretary of State:
Corporations & Charities Division
Secretary of State
P.O. Box 40234
Olympia, WA 98504-0234
Or file online at: ccfs.sos.wa.gov
Once filed, you’ll receive an official confirmation and can download your formation certificate for your records.
🧩 4. Information Needed for Certificate of Formation in WA
To file correctly, you’ll need the following details ready:
- LLC Name: Must be unique and end with “LLC” or “L.L.C.”
- Registered Agent: Name and physical address in Washington (no P.O. Boxes)
- Principal Office Address: The main business location (can be home-based)
- Duration: Most LLCs are “perpetual,” but you can specify an end date if needed
- Management Structure: Choose whether the LLC is member-managed or manager-managed
- Organizer’s Name and Address: The person completing the filing

📑 5. WA State LLC Operating Agreement: Do I Need One?
Washington doesn’t legally require an Operating Agreement, but it’s highly recommended.
An Operating Agreement outlines how your LLC is run — who owns what, how profits are split, and how decisions are made.
Even if you’re a single-member LLC, having one helps separate you from your business, reinforcing your liability protection and keeping things clear with banks, accountants, and the IRS.
If you’d like, I can provide a single-member Operating Agreement template specifically for Washington LLCs.
⏳ 6. How long does an LLC take to get approved in WA?
- Online filings: Usually 2–5 business days
- Mail filings: Typically 2–3 weeks
- Expedited option: Available online for faster turnaround (extra fee)
Once approved, you’ll receive your formation certificate and can immediately apply for your business license and EIN.
💵 7. How Much is Washington State’s LLC Filing Fee
