Title: There’s not much downside to being rich, other than paying taxes!  Authors: Ida Johansson, Tova Lindbäck & Elisabeth Lydahl Institution: School of Business and Economics at Linnaeus University Kalmar Program: Business Administration and Economics Programme, specialization in Accounting and Management Control Advisor/examiner: Petter Boye Co-examiner: Xiang Yu Background: Recent years, the demand for tax transparency has significantly increased. Several media scandals have exposed the existence of aggressive tax planning, which has affected society’s view on how tax contributes to a sustainable world. In line with the demand GRI formed their standard GRI 207: Tax 2019. Initially, tax transparency aimed to eliminate aggressive tax planning. Today, tax is also regarded as a contribution to society.  Purpose: The purpose of this study is to explain how GRI 207: Tax 2019 has contributed, and will contribute, to changing the view of tax as a sustainability issue. Further, we aim to explain which factors that may contribute to forced tax transparency in sustainability reporting in the future.  Method: An abductive and qualitative approach in order to create a deeper understanding of tax as a sustainability issue. The data has been collected through semi-structured interviews with tax experts and representatives of businesses who practise or had the intention to practice GRI 207: Tax 2019.  Conclusions: We have found that GRI 207: Tax 2019 has changed the view of tax as a sustainability issue, due to their quality mark and being a leading global actor. We believe several standards will exist in the future, but it’s tax transparency as a whole that will be requested rather than a specific standard. Investors and the media are the factors which will contribute to a forced tax transparency in the future. Finally, we have identified four issues, where a legal requirement is the key.
