In a past post, I noted how tax arrears in Greece were both high as well as highly concentrated (here). The General Secretariat for Information Systems (GSIS) has just published a detailed list of the corporate entities that owe more than €150,000 in tax arrears. There are 6,000 companies on the list with arrears of €30.9 bn. There is not much new to say (see my previous post) except to underscore just how skewed the data is: 10 companies alone owe €4.4 bn with train company OSE leading the way; the top 100 companies owe €11.7 bn. Of the 6,000 companies with arrears, 212 make up 50% of the total. No doubt the publication of the names will produce both pressure as well as intense reaction. Will it help with tax collection? We'll see.
