Last year we published a document entitled Ten Reasons to Defend the Corporate Income Tax, outlining how the tax is under constant attack, in country after country, and explaining why it is one of the most precious of all taxes. Now there’s another fascinating paper, rich in insight and detail, from US economist Kimberly Clausing, entitled “Strengthening the Indispensible U.S. Corporate Tax.
While US-focused, it contains a lot of material that provides extensive further support for our own generic document, and argues that the corporate income tax is becoming more, rather than less, important in our tax system(s). It also argues that tax rates for capital, which is currently taxed at lower rates than labour is, should be harmonised with the labour rate, and supports so-called ‘formulary apportionment‘ approaches to taxing U.S. corporations internationally.
