Two e-mail scams purportedly from the IRS recently landed in my “in” box from baffled friends. Like all e-mail attributed to the IRS, these were phonies.

One had an official-looking e-mail address with irs.gov on the end. The subject line said, “IRS USA for Businesses: Important messages to all business Accountants and Treasury Managers!” The main message told recipients to download information on recent changes to business and corporate tax laws, and offered an address to click on for more information, including “www1.irs.gov” in the URL.

Point 1:  There is only one official IRS Web site: www.irs.gov.

The other e-mail was scarier because it looked so real. It, too, was sent from an e-mail address with irs.gov on the end, and informed the recipient that she was due a tax refund of $93.60. To add to its verisimilitude, a copyright line for the IRS was posted at the bottom.

Clicking on the provided link led to a Web page with official-looking IRS letterhead, and that very familiar san serif typeface that says “I’m not kidding.” And what did the “IRS” want from my friend? Her Social Security number and a current credit card number—for who knows what kind of mischief. The only thing that gave away the scam was the URL that popped up on that second page: www.drunkenmedia.com.

Point 2: The IRS never communicates with taxpayers via e-mail. Even the electronic confirmation you get after filing electronically comes through the tax-prep software provider, not the IRS.

I checked later and both offending Web pages had been taken down. Someone had obviously reported them, a wise move.

Point 3: Never respond to e-mails that purport to be from the IRS.

Otherwise, you could become the victim of identity theft. Report any e-mails you receive from the IRS to phishing@irs.gov. Check the IRS Web site for more examples of common e-mail schemes.
