This is the seventh edition of our Public Trust in Tax series, the second in partnership with the OECD, and this yearalso sees CA ANZ join the publication, as they have on four previous occasions, together with ACCA and IFAC whohave been part of all seven editions. It continues to expand, covering a record 29 countries this year. Following onfrom the 2024 focus on Latin America, this year it deep dives into Asia. The data in this report will further enhance the OECD’s work on taxmorale. This is the first phase of a new project looking at tax moralein Asia. The next phase will include working to combine this data onpublic perceptions with insights and analysis from tax administrationsand government ministries to enhance understanding of the currentlevels of tax morale and the actions that are being taken to improvethis. Complementing this work with best practices and guidance willhelp support countries in their efforts to increase tax morale and buildeffective and trusted tax systems. Trust in tax remains as important an issue now as in 2017 when thefirst version of this survey was undertaken. The Fourth United NationsConference on Financing for Development, held in Sevilla in June2025, highlighted that domestic revenues need to be at the heart ofdevelopment and, through the Sevilla Commitment1, provided a rangeof approaches through which fiscal systems can play their required rolein development. Implementing reforms to realise this Commitment willrequire the public to trust the tax systems being implemented. Lee WhiteChief ExecutiveOfficer, IFAC Helen Brand OBEchief executive, ACCA For IFAC, ACCA and CAANZ, the findings about professional accountantswho work in tax remains extremely important and highlight the critical rolethat the accountancy profession plays in building trust in the tax system.As professional accountants, we need to both think how to sustain thetrust placed in us and seek to broaden our impact. We also need toincrease the reach of our professional expertise, for example through themedia and public engagement, to help ensure more widespread accessto trusted information on tax.
