The Wall Street Journal celebrates the putative announcement of a nine percentage point reduction in Germany’s corporate tax rate. There is a dark lining to this silver cloud since there are hidden tax increases included in the proposal. The initiative also leaves in place some loopholes that could have been used to finance even lower tax rates, but it is nonetheless encouraging to see that one of Europe’s biggest cheerleaders for tax harmonization is being forced to join the tax‐​cutting bandwagon: 

Europe’s vibrant tax competition has finally reached Germany, which usually prefers to sit back and tut‐​tut while its neighbors cut taxes and grow their economies. Chancellor Angela Merkel’s cabinet today is expected to slash the top corporate tax rate to 29.8% (the average federal‐​municipal rate) from 38.7%. That’s still a far cry from flat‐​tax Slovakia’s 19% or Ireland’s 12.5%. But it would move Germany from the third‐​highest corporate tax rate in the OECD, after Japan and the U.S., to a more comfortable middle position. …The Finance Ministry missed the opportunity to simplify the tax system in one go. Getting rid of tax exemptions for corporations — thereby broadening the tax base — would have been a useful move. It would have had the added benefit of giving Berlin more room to cut rates beyond the planned nine percentage points. …Over the long run, the corporate tax cuts will likely increase revenues by encouraging economic activity and tax compliance.
