Plain-English summary

Engineering services were exempt when a licensed engineer developed new engineering concepts and original designs relating to a client's products.

Design or drafting services were taxable. The ruling distinguished the engineer who created the ideas, concepts, designs, and specifications from the draftsman or designer who used that work to perform separate services.

What this means for you

The historical ruling classified the service by who developed the original concepts and what work was actually performed, rather than treating every service connected with an engineering project alike.

Common questions

Were original product designs by a licensed engineer exempt? Yes under the cited exemption.
