We are pleased to invite delegates from your tax administration to a two-day training session on the collection and use of ISORA (International Survey on Revenue Administration) data. The workshop is co-organised by IOTA and the OECD FTA (Forum on Tax Administration) and hosted by the Norwegian Tax Administration (NTA).

The purpose of the training session is to:

  • provide insight into the changes made to the 2020 survey;
  • provide guidance and recommendations for an efficient collection process that ensures high quality data;
  • discuss areas of using ISORA data;
  • exchange strategies for stimulating use and creating buy-in with management;
  • discuss challenges and best practice related to ISORA completion and use; and
  • encourage networking among ISORA stakeholders.

Target audience for the training session are tax officials from OECD-FTA and IOTA member administrations who will be involved in completing ISORA 2020 or are using/ will use ISORA data for analytic and strategic purposes. Prior ISORA experience is advantageous but not necessary.
