IRS can read your email with no warrant...

The Internal Revenue Service claims that it has the right to read the private emails, text messages and other electronic communications without a warrant because, the agency claims, Americans have no reasonable expectation of online privacy.

The revelation comes from a Freedom of Information Act request for information pertaining to the IRS policy for conducting investigations of tax crimes. In a 247-page response, the IRS provided a vague answer to the question of whether it conducts warrantless searches of email inboxes and other electronic communications, which erred on the side of “yes." .........

The most current version of the IRS handbook states expressly that the agency still concedes that it isn’t required to obtain a warrant in order to search emails older than 180 days.

The IRS says it has the right to go into your account and read them.

A bit of background is necessary here. When it comes to getting a warrant to read your email, the relevant law is the Electronic Communications Privacy Act, which was enacted way back in 1986. As you might expect, the law is a bit dated: According to the law, a government agency can read your email without a warrant as long as the email has been opened, or if it's been sitting in your inbox for more than 180 days. Only unopened email that's been on the server for less than 180 days requires a warrant. 

Before that decision, the IRS was certainly opening emails without warrants -- in fact, the ACLU got hold of an internal handbook claiming that the "the Fourth Amendment does not protect communications held in electronic storage."


The IRS has lots of ways to investigate you if it thinks you've been hiding something. In addition to searching your email and voicemail, it may also search your social media accounts for incriminating information (though it denies that it may audit you based on something it finds on one of those accounts, insisting that audits are based strictly on your filed return.)
