Taxpayer Compliance Research

The IRS seeks to help taxpayers comply with their tax obligations voluntarily and timely. The articles and publications on this page contain research related to taxpayer compliance. Compliance measurement research, also known as the tax gap, examines how much tax is not paid voluntarily and timely. Another set of research looks at the causes of taxpayer compliance.


Here you will find forecasts of the number of returns to be filed for tax forms within the individual, tax-exempt, and business areas. These statistical projections are developed by the IRS office of Research.
