CT Ruling 89-203 Sales and Use Taxes 1989-11-08

Were process-engineering services for industrial environmental problems subject to Connecticut sales and use tax?

Short answer: No under this historical ruling. DRS said X Corporation's process-engineering services, including wastewater treatment and hazardous-waste management for industrial clients, were not taxable as building engineering or building planning and design. DRS says AN 94(3) obsoleted the ruling.
