Obtaining a Seattle Business License Tax Certificate, commonly known as a Seattle business license or general business license, is mandatory for anyone conducting business activities within the City of Seattle. It’s an essential legal requirement, and understanding its application, renewal, and management processes can help you stay compliant and avoid potential penalties.
How to Apply for a Seattle Business License Tax Certificate
Seattle business licenses must be renewed annually by December 31st, regardless of when they were initially obtained. Business owners can conveniently apply for or renew their licenses online or by mail.
Applying Online via FileLocal
Seattle offers a user-friendly platform called FileLocal for business license applications and renewals. Business owners will usually need a Unified Business Identifier (UBI) number to start the application. If your business doesn’t legally require a UBI number, skip this step by selecting “Skip UBI Questions” and “Enter UBI Later.”
Upon completing the application online, new applicants can immediately print their temporary business licenses directly from the FileLocal portal, making the process quick and seamless.
Applying via Mail
Alternatively, you can apply by mail. First, download the application form from Seattle’s official website, complete it, and mail it along with your payment. Processing via mail typically takes between one to six weeks.
