Why

Connecticut lists business analysis, management, management consulting and public relations services as taxable in Conn. Gen. Stat. § 12-407(a)(37)(J). Other professional services are generally not taxed unless another enumerated service in § 12-407(a)(37) covers them.

For AI agents, AgentTax classifies consulting output as a digital service rather than a professional service, so this exemption analysis applies to human professional services.

How AgentTax classifies professional services

Advisory and consulting work performed by people: legal, accounting, management consulting and similar services. AgentTax routes AI-agent consulting work to its digital service category, not to professional services, because an AI agent has no licensed practitioner behind it.
