The Statistics of Income (SOI) Division of the Internal Revenue Service is responsible for conducting the Individual Tax Return Sample Study. SOI's annual Individual Sample is selected using a Stratified Bernoulli Sample. In return, the sample is used for cross-sectional estimation of information reported on the Tax Form 1040. This paper details changes made to the sample design as a result of analysis to evaluate potential improvements. Changes to SOI's Individual Tax Return Sample over time are necessary for better accuracy and effectiveness.
