Generally, charges to participate in tennis, racquetball, handball, squash, and pickleball provided by an operator of an athletic or fitness facility (AFF) are subject to business and occupation (B&O) tax under the Retailing classification, and the AFF must collect sales tax.
Non-retail sales
Amounts charged to participate in tennis, racquetball, handball, squash, and pickleball, where the activity is not provided by the operator of an AFF, are subject to B&O tax under the Service and Other Activities classification.
Note: Tennis, racquetball, handball, squash, and pickleball, are defined as activities of an AFF. The department will presume that these facilities are primarily used for AFF-related activities. It is up to the business to show otherwise.
