The emails have links that show an IRS.gov-like website with details pretending to be about the taxpayer's refund, electronic return or tax account. The emails contain a "temporary password" or "one-time password" to "access" the files to submit the refund. But when taxpayers try to access these, it turns out to be a malicious file.

"The IRS does not send emails about your tax refund or sensitive financial information," said IRS Commissioner Chuck Rettig. "This latest scheme is yet another reminder that tax scams are a year-round business for thieves. We urge you to be on-guard at all times."

The IRS also doesn't call to demand immediate payment using a specific payment method such as a prepaid debit card, gift card or wire transfer. Generally, the IRS will first mail a bill to any taxpayer who owes taxes. See Report Phishing and Online Scams for more details.
