AAT ethics offers an extensive library of interactive resources, including a section dedicated to the ethics of tax avoidance.Office for Tax Simplification (OTS) Described by its tax director, John Whiting, as being ‘of government but not in government’, the OTS is a quasi-independent body making recommendations on simplifying the UK’s fiendishly complex tax system.Its section on the Treasury’s website keeps you up to date with its latest developments. Not everything the OTS recommends is adopted by government, but it’s important to understand what this important advisory body is thinking: some day those thoughts might become law.Tax lobby groups Heavy on opinion, but still worth reading if you are interested in the debates and rows over tax that have become an evergreen feature of public life, tax lobby groups’ sites can be thought-provoking and entertaining.Two favourites that look at the tax world from different perspectives are the Taxpayers’ Alliance – which campaigns for lower taxes – and Tax Research UK, which campaigns for a stronger crackdown on tax avoidance and evasion.
