The IRS has launched a new initiative to improve tax compliance among high-income taxpayers who have not filed federal income tax returns since 2017. This effort, funded by the Inflation Reduction Act, involves sending out IRS compliance letters to over 125,000 cases where tax returns have not been filed since 2017. These mailings include more than 25,000 to individuals with incomes exceeding $1 million and over 100,000 to those with incomes ranging between $400,000 and $1 million for the tax years 2017 to 2021. The IRS will begin mailing these compliance alerts, formally known as the CP59 Notice, this week.

Recipients of these letters should act promptly to prevent further notices, increased penalties, and stronger enforcement actions. Consulting a tax professional can help them swiftly file late tax returns and settle outstanding taxes, interest, and penalties. The failure-to-file penalty is 5 percent per month, capped at 25 percent of the tax owed. Additional resources are available on the IRS website for non-filers.

The non-filer initiative is part of the IRS‘s broader campaign to ensure large corporations, partnerships, and high-income individuals fulfill their tax obligations. Non-respondents to the non-filer letter will face further notices and enforcement actions. If someone consistently ignores these notices, the IRS may file a substitute tax return on their behalf. However, it’s still advisable for the individual to file their own return to claim eligible exemptions, credits, and deductions.
