Doing Business in Ilwaco


There will be a significant change to business licensing requirements as of January 1st, 2019. More information will be posted on the Business Licensing Services website as well as this website, and will be sent as a Public Notice. If you'd like to be added to our Public Notice list, please email



  • STARTING A BUSINESS: The City of Ilwaco contracts with the Pacific County Economic Development Council (PCEDC) to provide assistance to new businesses. PCEDC has a number of resources for Starting a Business. Be sure to check out the New Business Checklist and FAQ, as well as other resources on their website.
  • BUSINESS LICENSE: Ilwaco business licenses are issued and renewed online or by mail by the Washington State Business Licensing Services.
  • BUSINESS & OCCUPATION TAX REPORTING: Businesses with an Ilwaco endorsement on their business license must file Business & Occupation Tax Reports (quarterly or annually based on annual revenue) as long as the license is active, whether or not they conduct any business or collect any revenue in Ilwaco. The forms are generated from a new program and will be mailed to businesses within 2 weeks of the end of each quarter for quarterly reporters or the end of the year for annual reporters, so there is no need to print the form from this site (if needing to report for a different time period click here). If a business doesn't receive a report, they will need to contact the City Clerk to make sure that their business information is accurate in the new system. More information is listed on the back of the report.
