Privacy and Security


The Department of Revenue protects the privacy of the visitors to the department website. The information that is revealed about you from your visit to this website depends upon what sections of the website you visit and what actions you take during your visit. However, no personally identifying information (such as your name, address, or phone number) will be captured by visiting this website, unless you voluntarily choose to provide it.

Employees of this department are prohibited from disclosing any information you provide, except as provided by law. Personal information you provide is used primarily for tax administration purposes. When personal information is stored by the department, it is in a secure location and is accessible only to designated staff.

Within the department website, visitors are provided with tax-related information and opportunities to contact the department. When you choose to contact the department by email or by another means provided on the department’s website, you will need to include some contact information so that the department may reply to your inquiry. If you prefer not to contact the department by email or through the website, you always have the option of contacting the department in-person, by telephone, or by mail.


The Department of Revenue has taken several steps to safeguard the integrity of its telecommunications and computing infrastructure, including but not limited to authentication, monitoring, auditing, and encryption. Security measures have been integrated into the design, implementation and day-to-day practices of the entire department operating environment as part of its continuing commitment to risk management.

The e-Services system uses SSL technology for secure transmission of information. The Secure Sockets Layer (SSL) protocol has become the universal standard on the web for authenticating sites and for encrypting communications between users and web servers. This means that users can confidently send private data, such as credit card and Social Security numbers, to a website, trusting that SSL keeps it private and confidential in transit.

When contacting the department by email, the department discourages visitors from including private information such as Social Security numbers. Email transmissions are not secured to prevent unauthorized viewing. When the department receives information from visitors through email or another means provided by the website, the information is treated and used in the same manner as information that is received through the U.S. mail or by telephone. It is given the same protection and guidelines for nondisclosure of that information.
