Tax phishing is target of new IRS registration rule

August 5, 2007

Fed up with scammers using Web sites that look and sound official, the IRS has established a new e-filing rule.

By next Thursday, Aug. 9, all authorized IRS e-file providers that obtain taxpayer information via the Internet, either directly or through third parties, must submit to the IRS the following information via an encrypted Excel spreadsheet:

  1. The provider's Electronic Filer Identification Number (EFIN);
  2. The name of a Principal or Responsible Official shown on the e-file application for the EFIN; and
  3. The Uniform Resource Locators (URLs) of all web sites that are used to e-file federal returns; that are portals or allow access to the provider's online e-file software: or are used to obtain taxpayer information for the purpose of preparing and e-filing federal returns.

So what does this mean for all of us who send Uncle Sam our 1040s electronically? As fas as what you and I typically do, nothing.

But when it comes to making sure that our e-filing is legit, the IRS believes the new requirements will help.

Creative criminals: Criminals are, by nature, brazen. They think they are smarter than anyone and can get away with anything. But most crooks, online and otherwise, don't go as far as to blatantly advertise their criminal enterprises a la the fake URL below.

Go ahead and check it. You'll get a "page and/or server not found" message, at least until someone decides to claim the URL.

When it comes to fake tax sites, the names usually sound very real. Some, as blogged about here, rely on slight spelling alterations or URL extension changes to dupe taxpayers into using their "services." Others, blogged about here, pose as free file sites in order to hijack filers' personal data.

New federal phishing filter: To combat these and other tax Web scams, the IRS is taking the newly required registration info and developing a universal catalog of URLs of authorized IRS e-file providers.

That should help investigators more quickly identify and validate a URL that might be suspected of fraudulent tax preparation and/or phishing for taxpayers' personal tax and financial data.

E-filing companies that don't provide the required data to the IRS by next week could see their business shut down.

In addition, says the IRS, an authorized e-file provider that fails to comply with the new rules could be suspended or expelled from participation in federal e-filing activities.

And non-validated Websites could see their data seized, especially if the IRS or the Treasury Inspector General for Tax Administration (TIGTA) believe that the site is "engaging in fraudulent schemes."

As for future online e-filing operations, providers must submit the same information to the IRS prior to the Web site being publicly accessible.

You can read the IRS official announcement and get additional information at the agency's FAQs page. If you have other questions about the new registration rule, you can e-mail efileurlreg@irs.gov.

TAX-SAVVY WAYS 
TO WRAP UP 2026

It’s over! With October’s extended filing deadline behind us, it is now time to focus on year-end moves to reduce your 2026 tax bill. 

You’ll find ways to do just that on the Tax Tips page (see the More Tax Posts drop-down menu at the top of the blog), as well as the separate tax tip pages for each month, notably October through December. If you’re on the Tax Tips page, you’ll find a monthly list at the end of this column. If you’re on another blog page, you can head straight to the October tips; at the bottom of that tips page you’ll find links to all the other 11 months’ collections of tax advice.

Not to spoil what you’ll find in that tax advice, but it does cover such things as tax deductions for charitable donations, investment moves that could reduce tax due, and ways to max out your tax-favored retirement savings. 

Finally, as the year winds down, things get hectic. There are lots of other things to occupy our time, like the much more fun upcoming holidays. But don’t lose sight of taxes, since timing is key. To be of use, most tax moves must be made by the end of the tax year. That’s Thursday, Dec. 31, which also is the last business day of the year. 

So that you don’t miss that final tax year deadline, also keep an eye on the countdown clock below. It will keep you on top of just how much time is left to make important, tax-saving moves. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
