IRS has cautioned taxpayers to be very careful of scams consisting of e-mails requesting detailed personal information.
IRS generally does not send e-mails to taxpayers, does not discuss tax account matters with taxpayers in e-mails, and does not request security-related personal information, such as PIN numbers, from taxpayers.
Most of these scams involve tax refunds and economic stimulus rebate receipt.

These are all scams to steal to identity……Hence, beware…
