Despite the legal frameworks and large amounts of lost tax revenue, profit-shifting practices persist around the world. This column argues that fiscal authorities of high-tax countries face an incentive problem in combatting profit shifting to tax havens. Enforcement efforts are focused on relocating profits booked in other high-tax countries rather than those in tax havens. This can ultimately result in lower global tax payments of multinational companies. The results call for a global corporate tax reform in order to save resources that currently go to wasteful and inconsequential tax enforcement.

The problem of tax compliance is as old as the levying of taxes. Innovations in tax administration that induce high compliance rates at reasonable cost are extremely important to governments. This column demonstrates how the taille, a tax collection mechanism from medieval Paris, raised compliance by turning the social cost of tax evasion into a private one. It offers a tax collection model that is still relevant to governments today.

Enforcement of VAT requires accurate records of firm transactions that can be traced to both parties. This column describes how the Chinese government’s digitisation of the country’s VAT process increased enforcement, which in turn increased overall tax revenues in the short run. However, the increased enforcement caused firms to contract in the medium run, reducing the long-run gains in tax revenues.

Tax evasion remains a pervasive problem. Fighting it efficiently is crucial, as resources spent on enforcement can’t be spent elsewhere in society. This column describes the outcomes of an enforcement experiment targeting at-risk firms in the US. Notification of risk status by letter saw an increase in remittances of 34%, while notification by in-person visit increased remittances by 276%. Remitted taxes also increased for the network neighbours of firms that received an in-person visit.
