Recently, there has been emails going around supposedly send by the IRS (US Department of Treasury).
Please be aware that the email is fake and do not enter your tax information or credit card information.
The IRS will not ask for your credit card information or your personal information for that matter. If IRS wanted to give you a refund, they will mail a check or direct-deposit into your bank account.
This website is a fake and if you notice, when you click the link it takes you to a website in Cyprus. So stay away and mark that email as spam.
