Business License Requirements

If you are a business with a physical presence in DuPont or plan to conduct business within DuPont city limits, you will need to register your business with the City and State. The City of DuPont and the State of Washington, Department of Revenue, Business Licensing Service are involved in a combined licensing one-stop system that allows you to obtain state and city licenses at the same time. You will receive a master license from the state, showing both your city and state business licenses. The fee for a DuPont license is $75. Non-profit businesses are required to file with the City but there is no fee required with submission of a valid 501(c)3 exemption form. The license is for one year and expires with the State Master License.
