In FY 2017, more than 55 million taxpayers were assisted by calling or visiting an IRS office.
The IRS continued a years-long effort to fight tax-related identity theft on many fronts, with another 524 criminal investigations completed.
Of the taxpayers who participated in the 2017 Comprehensive Taxpayer Attitude Survey (CTAS), 88 percent said it is not at all acceptable to cheat on their income taxes, and nearly all (95 percent) believe it is a civic duty to pay their fair share of taxes. Additionally, most taxpayers (79 percent) are satisfied with their personal interactions with IRS. See the 2017 CTAS report for more details.
