Taxpayer Experience Interview – Late-Filed Returns OMB #1545-2212 The IRS would like to get feedback from taxpayers who filed a late tax return in order to better understand the filing issues faced by these taxpayers. As part of this effort, IRS has asked Westat, an established research company, to conduct a phone interview with taxpayers who filed one or more late returns. Invitation letters were sent to randomly-selected taxpayers inviting them to participate in the interview on a first-come, first-served basis. Participation is voluntary and confidential. Transcripts of the interviews, with all personally identifiable information removed, will be provided to IRS for research purposes only. A copy of the IRS letter that invites taxpayers to participate in the survey is provided below.
