In recent years tax authorities worldwide have implemented voluntary disclosure schemes to recover tax on offshore investments. Such Schemes are characterized by the acquisition of non-audit information on offshore holdings, and a subsequent opportunity for affected taxpayers to make a voluntary...

The Malawi Revenue Authority (MRA) implemented the Voluntary Compliance Window (VCW) in 2013/2014 fiscal year as a means of bringing non-compliant taxpayers into the tax net. The programme was a huge success in terms of revenue and the cost of collection at 0.8% was by far below the 3% benchmark...

The Norwegian Tax Administration operated multi-year random audits of personal income tax returns. We exploit this exceptional randomized setup to estimate the effects of tax audits on future compliance explicitly distinguishing between dynamic responses of compliant and noncompliant audited...

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...

Governments increasingly use changes in tax rules to combat evasion. We develop a general approach to point-identify tax compliance along with supply and demand elasticities; identification requires data on prices and quantities before and after changes in tax enforcement and a demand or supply...

This paper develops a simple model to explore whether a higher detection probability for offshore tax evaders-e.g., because of improved exchange of information between countries and/or due to digitalization of tax administrations-renders it optimal for governments to introduce a voluntary...

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...

Tax enforcement can be prohibitively costly when market transactions and participants are difficult to observe. Evasion among market participants may reduce tax revenue and provide certain types of suppliers an undue competitive advantage. Whether efforts to fully enforce taxes are worthwhile...

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...
