I am self-employed and my work involves preparing drawings and 3D models.
When ding my VAT RTD one of the questions it asks is:
"Did you purchase goods or services that are not for resale but where VAT paid can be claimed as an input credit?"
Eg you bought ink for the drawings. It cost €1,230 (€1,000 + Vat €230)
You claimed VAT back (i assume)
Then this €1,000 is goods that you did not resell and used €230 as in input credit
