How to Start an LLC in Washington (2026 Guide)
Washington charges $180 to form your LLC — higher than many states — but has no personal income tax at all. That trade-off sounds simple until you learn about the B&O tax: a gross receipts tax owed on your total revenue, not your profit, even in a year you lose money.
The formation base is $180, plus the applicable online processing charge. File the Initial Report within 120 days: free with formation or $10 separately later. The Annual Report is $70, due the last day of the anniversary month. There is no blanket 2026 B&O exemption below $250,000. DOR may grant active non-reporting status below $125,000 in annual B&O gross income when all conditions are met, including no retail-sales-tax collection or other DOR tax/fee duty and the public-utility limit where applicable. Existing filers must request a status change. The $250,000 filing-relief threshold takes effect January 1, 2029.

What to Know Before You Form in Washington
Washington's formation process is straightforward, but its tax structure genuinely differs from most states in this series. What's worth understanding clearly before you commit:
- A $180 formation fee — with a $20 online processing fee added, most founders pay $200 total to file online.
- No personal income tax — a real, genuine draw for many founders considering Washington.
- The Business & Occupation (B&O) tax — owed on gross receipts, not net profit, with essentially no deductions for costs. This is the honest trade-off behind "no income tax."
- Two separate early filings — your Certificate of Formation, then a required Initial Report within 120 days (free if you formed online).
B&O depends on classification, gross receipts and available credits. There is no blanket 2026 B&O exemption below $250,000. DOR may grant active non-reporting status below $125,000 in annual B&O gross income when all conditions are met, including no retail-sales-tax collection or other DOR tax/fee duty and the public-utility limit where applicable. Existing filers must request a status change. The $250,000 filing-relief threshold takes effect January 1, 2029.
How to Start a Washington LLC in 8 Steps
Your name must be distinguishable from every Washington entity and contain "LLC" or "Limited Liability Company." Search free through the Secretary of State.
Every Washington LLC must continuously maintain a registered agent — a WA resident or authorized entity with a physical in-state street address.
File the Certificate of Formation
$180 base filing fee; the current online route adds its processing charge. Check the SOS queue and accepted record rather than relying on a fixed approval time.
An operating agreement can address ownership, management and applicable default rules. Mandatory law still controls; banks set their own documentation requirements.

Your federal tax ID for banking, hiring, and Washington Department of Revenue registration. Always free at IRS.gov.
File Your Initial Report, Then Annual Reports
Initial Report within 120 days: free when filed with formation, $10 when filed separately later. Annual Report $70, due the last day of the anniversary month.
Get Business Licenses & Permits
A Washington Business License is required statewide for most businesses — genuinely different from many states with no general license.

What a Washington LLC Really Costs (2026)
| Cost Item | Amount | When |

| Certificate of Formation (required) | $180 (+$20 online) = $200 online | One-time, at formation |
| Initial Report (required) | Free with formation; $10 separately | Once, shortly after formation |
| Annual Report (required) | $70 | Every year, anniversary month |
| Washington Business License | $50 processing + applicable endorsements | One-time (with renewal, varies) |
| Registered agent service (optional) | Actual service quote and renewals | Annual, if hired |

Online formation costs $200 and the annual report is $70. Budget the separate business-license application processing fee, applicable endorsements, taxes and optional provider charges. These two SOS fees are not an all-in business budget.

B&O taxes gross receipts rather than profit; ordinary operating costs generally are not deductions. Service & Other Activities uses 1.5% below $1 million, 1.75% from $1 million to under $5 million, and 2.1% at $5 million or more, based on prior-calendar-year taxable income in that classification for the business or affiliated group. Special exceptions apply. Small-business credits can reduce the amount due. City B&O has separate rates, thresholds and returns. DOR service-rate notice.
Washington LLC Taxes at a Glance
Washington has no general personal income tax, but that does not mean every owner or transaction is tax-free. State B&O, sales, capital-gains excise and city taxes can apply under their separate rules, along with federal taxes. Use the official rate and location tools for the activity; no combined sales-tax average is assumed here.
Plan tax and reporting separately. Estimate the correct B&O classification and small-business credit, then confirm your DOR reporting status. Zero state B&O due does not itself end sales-tax or city filing duties. DOR non-reporting conditions.
