IRS New JSEIT Unit Will Use Crowdsourcing, Cooperative Intra-Agency Intelligence and Media Alerts to Quash Emerging Tax Fraud Schemes

Announced in June, the Joint Strategic Emerging Issues Team, or JSEIT, combines expertise from units across the agency, including Criminal Investigation, Tax Exempt/Government Entities, Large Business & International, and Small Business/ Self Employed.

JSEIT’s goal is to act before a tax scheme becomes a widespread issue. Acting as a conduit between taxpayers with compliance issues and the relevant IRS division, JSEIT hopes to provide early communication to prevent abusive fraud. Any transactions that have already been identified as abusive by the IRS will not be in focus.
