Compensation received from the Federal Communications Commission (FCC) or other governmental agencies for providing Telecommunications Relay Services (TRS) are subject to business and occupation (B&O) tax under the service and other activities classification.
Customers who purchase telecommunications plans that provide TRS are still subject to retail sales tax. This includes purchasing a wireless phone plan with a telecommunications provider that provide TRS free of charge.
