Tammy Mills forwarded WITN an email she received. The email has an IRS logo that looks very authentic. The email says Tammy's eligible for a tax refund of $2839,49. You can see the comma is clearly where a period should be if we're dealing in American dollars. In Europe, however, a comma is used instead of a period. Hard to imagine Uncle Sam would make either a typo or talk about money in a way that's more European than American.

Remember, the IRS does not initiate taxpayer communications through e-mail. Also, do not open any attachments to questionable e-mails. The IRS says they might have a virus.

Tammy says she knew this was a scam because she already received her tax refund. But she said she clicked on the link in the email. It took her to a site where it asked for all sorts of personal information, a true phishing scam.
