Every year, you must renew your license with the Business Licensing Service at the Department of Revenue. They'll mail you a reminder notice about 45 days before your license expires. The expiration date is printed in the top right corner of your license.
Mail your completed renewal notice and a check or money order for the fee (payable to the Department of Revenue) to:
State of Washington
Business Licensing Service
PO Box 9034
Olympia, WA 98507-9034
Note: Your renewal won't be official until the Business Licensing Service receives payment of all your fees.
Your annual license renewal fees will be listed on the reminder notice you get in the mail. If your license expires before your renew it, you may need to pay additional late fees.
