About Seattle Business License & B&O Tax Estimator
LicenseBeacon builds simple, honest cost estimation tools for people starting and running businesses. City fee pages can be hard to navigate, so our goal is to give you a trustworthy ballpark number in one click, before you ever pick up the phone.
Our estimates come straight from the City of Seattle's published tax rules, not from guesses or national averages. When the city updates its rules, we update our math.
We are an independent resource. We are not a government agency, and we are not affiliated with the City of Seattle or the State of Washington.

This estimator is one of six city guides in the LicenseBeacon network, built to answer one question honestly: what will it actually cost to be legal in Seattle? The other city guides cover Fort Worth, Los Angeles, San Francisco, Philadelphia, Atlanta and Seattle, and each one works from that city's own published fee schedules and tax rules, not national averages.
