You must also be aware of your tax requirements.

How do I apply for a license?

The City of Seattle currently is not accepting electronic forms and so fees and applications must be either sent in the mail or delivered in person to: City of Seattle, Revenue and Consumer Affairs, 700 5th Avenue, Suite 4250, P.O.

What is the cost of the licenses?

All fees must be paid either in the form of a check or money order and made payable to the City of Seattle. Fees are based on the total gross income of the business and/or value of current products. There are some businesses or services that require special requirements or additional fees. Please carefully review the application to see if they apply to your business.

Licenses are valid until the end of the calendar year (December 31st). If a license is issued during the final six months (after July 1st) of the year, the fee will be half of the standard rate. Here are the costs of the licenses:
