Washington consistently ranks among the best states for business, and for good reason: it has no personal income tax, a strong economy, and a rapidly growing Hispanic market in Seattle, Tacoma, and the Yakima Valley. But starting a business in Washington comes with a catch that almost no one tells you about: the state doesn't tax you on what you earn, it taxes you on what you bill. This guide outlines the actual steps, verified 2026 costs, and the B&O tax trap that surprises everyone who arrives expecting Washington to be a tax-free state.
Why Washington is so appealing, and what's the catch?
The good news is real: there's no state personal income tax, the business ecosystem is one of the strongest in the country, and there's a large and well-established Hispanic community. Amazon, Microsoft, Boeing, and Starbucks are all there, along with a whole network of suppliers and services.
What you need to understand before signing anything: Washington changed the income tax to the B&O tax , a tax on gross income . It doesn't deduct expenses. That means you can have a year of losses and still owe money to the state. It's not a reason not to come; it's a reason to calculate carefully.
How to start a business in Washington step by step
1. Choose your structure
For most small businesses, an LLC is the starting point: it separates your personal assets from the business and is simple to maintain. If you've never formed one, first review how to open an LLC step by step.
2. Present the Certificate of Formation
This is the document that creates your LLC with the Secretary of State. It costs $200 online ($180 for the certificate plus $20 processing fee). You'll need an available name, a registered agent with a physical address in Washington (this can be yourself if you live there), and the business address. It's done through the Washington Secretary of State's website.
3. Submit the Initial Report
Here's an easy money-saver that people often miss: if you submit it at the same time as your Certificate of Formation, it's free . If you wait, you have 120 days and it costs $10 . Submit them together and forget about it.
4. Saca tu EIN
Your EIN is your tax identification number with the IRS, and it's free . You need it to open a business bank account, hire employees, and file taxes. We explain the entire process: what an EIN is and how to get one for free.
5. Apply for your state business license and your UBI
Washington centralizes this process through the Department of Revenue with the Business License Application. The base cost is around $90 , plus the endorsements from the city where you operate, which are paid separately and vary. Upon approval, you receive your UBI (Unified Business Identifier), which is the number the state uses to identify you for all purposes. The process takes about 10 business days, and if you need municipal endorsements, it can add another two or three weeks.
6. Open the business bank account
Never mix your personal money with your business money: it's the fastest way to lose the legal protections of your LLC. If you don't have a Social Security number, there are banks that will open an account with an ITIN and passport; we explain this in detail in our article on how to open a business bank account without an SSN.
The real costs of opening in Washington (2026)
- Online Training Certificate: $200
- Initial Report: $0 if it goes with the certificate, $10 if it goes later
- A: $0
- Business License Application estatal: about $90 + city endorsements
- Annual Report: $ 70 per yearIt expires on the last day of your LLC's anniversary month.
- Registered commercial agent (optional): between $50 and $150 per year
In short: around $290 to $300 to get started and $70 a year to keep it running, not including municipal endorsements or permits for your business. Always check the figures at dor.wa.gov and sos.wa.gov before budgeting: they change from year to year.
The B&O tax: the tax you absolutely need to understand
The Business and Occupation tax is levied on your gross income, without deducting expenses. The 2026 rates are:
- Retail: 0.471%
- Wholesale and manufacturing: 0.484% (both rise to 0.5% on January 1, 2027)
- Services and other activities: 1.5% If you billed less than $1 million the previous year; 1.75% between $1 million and about $5 million; 2.1% above that
Pay attention to the details: if you provide services, your tax rate is three times the retail rate. A consultant who bills $200,000 a year pays around $3,000 in B&O tax, even if their expenses were high and their profit low. Calculate this from day one and factor it into your prices. If you want to understand how this fits with the rest of your obligations, check out our guide to the 3 taxes every business owner should understand.
Costly mistakes in Washington
Three, and they're repeated. Believing that "no income tax" means "no taxes" : the B&O tax will still come and won't forgive a bad year. Forgetting the Annual Report : it's $70, but if you let it expire, the state can administratively dissolve your LLC. And skipping city endorsements : Seattle, Tacoma, and several other cities require their own license in addition to the state one, and operating without it exposes you to fines.
Conclusion
Washington is a great state to start a business if you have your accounts ready. You can get your LLC up and running for under $300 and maintain it for $70 a year, which is cheap compared to California. The key is to factor the B&O tax into your pricing from day one and not to confuse "no income tax" with "free." If you do that, you'll have access to one of the most dynamic economies in the country and a Hispanic community that's already buying.
