Since 2015, Illinois has stopped more than $120 million in attempted identity theft and tax refund fraud thanks to increased data analytics and partnerships with the Internal Revenue Service (IRS) and other states. As criminals continue efforts to perpetrate fraud this tax season, the Illinois Department of Revenue (IDOR) is reminding taxpayers that we’re all in this fight together. IDOR suggests taxpayers protect personal information and tax data by following some simple guidelines: use security software with firewall and anti-virus protections, selecting automatic updates; be aware of phishing emails and phone scams that attempt to trick individuals out of personal information and money; and treat personal information as you would cash – don’t leave it lying around. More than 1.85 million taxpayers have filed their Illinois tax return within the first month of the 2019 Tax Filing Season. As fraud prevention efforts continue, taxpayers are reminded that if they receive an identity verification letter from IDOR, they may now authenticate their information electronically through IDOR’s free online account management program, MyTax Illinois. In the past, identity authentication required written documentation sent via paper mail, creating a time-consuming process for the taxpayer and IDOR.
