OMB #1545-2212 The Taxpayer Compliance Burden Survey is an important project that can benefit you and millions of other taxpayers. We've heard that amending an already-filed federal income tax return is time-consuming and expensive. This survey will allow the IRS to learn more about those costs. Your responses to the survey will help the IRS better understand the time and money spent by taxpayers amending returns. The information you provide will help the IRS learn how to improve its processes and reduce taxpayer burden. All information provided will be used will be used for research purposes only and participation is voluntary. Only those taxpayers randomly selected may participate in the study. We estimate that it will take about 10 to 15 minutes to complete. This survey is being conducted by Westat on behalf of the IRS. Respondents will be sent either the IRS Standard Invitation Letter or the IRS Online Survey Invitation Letter. A sample of each letter is provided below. A sample copy of the survey is also provided.
