The Dutch Parliament has passed legislation for a new income tax that abolishes the current tax on personal capital income and substitutes it by a presumptive capital income tax, which is in fact a net wealth tax. This paper contrasts this wealth tax with a conventional realization-based capital...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

We provide quasi-experimental evidence on the income tax-induced migration of foreign high-income households living in Switzerland by exploiting the differential tax treatment of UK and US households. While the two groups are similar in terms of non-tax sorting preferences, US households are...

The 2017 US tax legislation - widely referred to as the Tax Cut and Jobs Act (TCJA) - fundamentally transformed the US system of international taxation. It ostensibly ended worldwide taxation but introduced, for instance, a new tax on "Global Intangible Low-Taxed Income" (GILTI). This paper...

The growing dissatisfaction with perceived distributional inequality and budgetary constraints gave rise to a discussion on the (re-)introduction of wealth taxes. Wealth taxes are typically levied on private wealth, in some countries also on corporate wealth. To avoid misleading statements...

Recent books by Thomas Piketty (Piketty, 2014) and Anthony Atkinson (Atkinson, 2015) have brought the annual wealth tax back on the policy agenda. Both authors suggest using the annual wealth tax to supplement the redistributional effects of the income tax, assigning it a role as a...

Tax administrations use machine learning to predict risk scores as a basis for selecting individual taxpayers for audit. Audits detect noncompliance immediately, but may also alter future filing behavior. This analysis is the first to estimate compliance effects of audits among high-risk wage...

We study the effects of wealth taxation on reported wealth. Our analysis is based on data for Switzerland, which has the highest rate of annual wealth taxation in the developed world. While the wealth tax base is defined at the federal level, tax rates vary considerably across locations and over...

We provide novel evidence on the linkages between capital taxation and charitable giving on three fronts. First, we use quasi-experimental variation in the annual Norwegian wealth tax to study the effect on how much households give. Inconsistent with the notion that households give more in order...

We study how reported wealth responds to changes in wealth tax rates. Exploiting rich intranational variation in Switzerland, the country with the highest revenue share of annual wealth taxation in the OECD, we find that a 1 percentage point drop in the wealth tax rate raises reported wealth by...
