State law requires regulated utility and transportation companies to file annual reports and pay regulatory fees to the commission. If you operated at any time during the reporting year, you are required to file an annual report.
All annual reports and regulatory fees must be received by the commission no later than May 1 each year. Postmark dates are not considered the date received. It is strongly recommended to use a mail delivery service with delivery confirmation or to file online to receive an email notification of receipt.
For more information about the annual reporting process and requirements, please reference the 
Annual Report FAQ or email annualreports@utc.wa.gov.
