Washington LLC Business License & Permits (2026)
Unlike many states in this series, Washington actually does require a statewide Business License for most businesses — here's what it costs and how it connects to your B&O tax account.
Washington requires a statewide Business License (around $90) from the Department of Revenue for most businesses — genuinely different from many states, which have no general statewide license. This single registration also sets up your B&O tax account. Beyond that: a seller's permit is bundled into the same Business License if you sell taxable goods, since Washington charges a 6.5% state sales tax plus local rates; state professional licenses apply for regulated fields; and many cities — including Seattle, Tacoma, and Bellevue — require their own separate local business license.

The Statewide Business License
Washington is genuinely different from many states here. Most states in this series have no statewide general business license — Washington does. Nearly every business needs a Washington Business License, roughly $90, obtained through the Department of Revenue. This single application is also how you register for your B&O tax account, so it's not an optional extra step — it's a required part of getting your LLC properly set up to operate and pay taxes in Washington.

Local City Licenses (Layered on Top)
Many Washington cities — including Seattle, Tacoma, Bellevue, Bellingham, and others — require their own separate local business license, in addition to the statewide license. Some of these cities also impose their own local B&O tax, entirely separate from the state B&O tax, with different rates and thresholds. If you're operating in or near one of Washington's larger cities, budget time to check that city's specific requirements directly — don't assume the statewide license covers everything.
Sales Tax Collection
- State rate — 6.5%: bundled into your Business License application if you're selling taxable goods.
- Local add-ons: push the combined average to around 9.37%, among the higher combined rates nationally.
- Economic nexus: $100,000 in gross Washington receipts triggers registration requirements for remote sellers — the same threshold that applies to B&O tax nexus.
Ahmad Adil's Take: the biggest licensing surprise for founders coming to Washington from a "no general license" state is realizing this state actually does require one — and that it's genuinely tied into your tax setup, not just a formality. If you're operating in Seattle specifically, budget extra time: between the statewide license, a possible separate city license, and Seattle's own local B&O tax, this is one of the more layered licensing pictures in this entire series. Don't assume one registration covers you everywhere you do business.
