Preparer Security and Tax Identity Theft

Preparer Security and Tax Identity Theft


This page is designed to give tax preparers the information they need to meet their security obligations and to improve their defenses against tax related identity theft which includes safeguarding their computer systems from cybercriminals. It will also let preparers know the latest ways identity thieves are attempting to obtain personal information from individuals.

Cybercriminals continue to step up their attacks on tax preparers. Therefore preparers need to take steps to protect their client’s data and their computer networks from these threats.

It is important to note that tax preparers are required by federal law Gramm-Leach-Bliley Act of 1999) to create and maintain a written data security plan. The Federal Trade Commission administers this law and created a Safeguards Rule to administer it.

Just to give you an idea the extent of the threat to preparers during last year’s filing season the IRS received five to seven reports per week from tax firms that had experienced a data theft. Through early November 2018, the IRS received 234 reports for the year. This was a 29 percent increase from 2017. These are just the tax firms that reported to the IRS, which means that there were probably hundreds more tax practitioners who also experienced data theft during 2018.

Here are basic security steps that preparers should take:

  • Learn to recognized phishing emails. Never open a link or any attachment from a suspicious email.

  • Create Better and Stronger Passwords

    All preparers should review the new, stronger password guidance for all of their online accounts.
