Frequently asked questions
Self-employed engineer with a VAT number: is ATECO code 71.12.10 correct?
I provide construction management and site supervision: 71.12.10 or integrated project management?
Usually 71.12.10, because it includes construction supervision and engineering project management. When you combine design, construction management and maintenance in an integrated, multi-discipline service, the code is 71.12.20.
I design systems and technical specifications for 3D printing: does this fall under engineering 71.12.10?
Yes. The IT development of projects and technical specifications for 3D printing is explicitly covered by 71.12.10, alongside the design of building plant and information systems. If you write management software for a client, that is software programming and belongs under 62.10.00.
