SeaTac city license

Requirements and fees

General business license
Variable

The city of SeaTac requires a license for all businesses located within city limits, or conducting business within city limits. If you are not sure if you will do business within the city limits, contact the city directly before you apply.

If you will have more than one business located on a single property, you must complete a separate application for each business.

License fee is determined by number of employees (FTEs) who work within the city limits of SeaTac.

Method for calculating FTEs

If you have reported employment to the State Employment Security Department, use the employee count from your most recent Unemployment Compensation Quarterly Report. A copy of the report may be required by the city of SeaTac for verification.

If you have not reported employment, estimate the maximum number of employees to be employed at any one time at this location during the next 12 months.

Convert part-time personnel to full-time equivalents by adding total weekly hours worked; divide by 40, round up fractions.

The owner(s) will be included when determining the number of employees.
