This project examines how reminders affect tax filing among lower-income nonfilers (individuals who did not appear on a filed tax return but had income reported by third parties to the Internal Revenue Service). We present novel data on this population and results from two randomized controlled...

Each year, the United States Internal Revenue Service (IRS) sends notices to selected taxpayers who claim Earned Income Tax credit (EITC) benefits to request additional documentation to verify those claims. This paper uses administrative tax data to examine the impacts of these correspondence...

We investigate the response of small businesses operating as sole proprietorships to Form 1099-K, an information report released in 2011 which provides the Internal Revenue Service with information about payment card sales. Theory and distributional analysis isolates affected taxpayers, who...

Governments and non-profits devote substantial resources to increasing take-up of the Earned Income Tax Credit (EITC) through educational outreach. We study a different approach: policies that encourage tax filing. In a large field experiment, we find that IRS letters about free tax preparation...

This paper studies tax evasion at the top of the U.S. income distribution using IRS micro-data from (i) random audits, (ii) targeted enforcement activities, and (iii) operational audits. Drawing on this unique combination of data, we demonstrate empirically that random audits underestimate tax...

Tax enforcement may affect both the behavior of those directly treated and of some taxpayers not directly treated but linked via a network to those who are treated. A large-scale randomized field experiment enables us to examine both the direct and network effects of letters and in-person visits...

This paper uses account-level information, reported to the IRS by foreign financial institutions under the Foreign Account Tax Compliance Act (FATCA), to produce new evidence on the foreign financial wealth of U.S. households. We find that U.S. taxpayers hold around $4 trillion in foreign...

Macroeconomic calibrations imply much larger labor supply elasticities than microeconometric studies. One prominent explanation for this divergence is that indivisible labor generates extensive margin responses that are not captured in micro studies of hours choices. We evaluate whether existing...

This paper uses administrative tax data to examine the long-term effects of an experimental job-search assistance program operating in Nevada in 2009. The program required randomly-selected unemployed workers who had just started collecting unemployment insurance (UI) benefits to undergo an...

We present quasi-experimental evidence on the effects of increasing the Early Retirement Age (ERA) on older workers' retirement decisions. The analysis is based on social security reforms in Austria in 2000 and 2004, and administrative data allows us to distinguish between pension claims and job...
