Email Security and Privacy Statement


The Department believes that personal information obtained from the customer on its site should be protected to the maximum extent possible, and that customers should be aware of the use of the information collected. This statement summarizes this information. If you have questions regarding the information, please contact the Department.

In order to maximize the security of the information presented, customers should:

a) Take necessary care to protect the confidentiality of any identification number or password that is used; and

b) If using a public access computer (such as in a library), take steps to "log off" the browser when exiting the application.

E-mail Transmissions

E-mail transmissions are not always secure. In no case will the Department send Federal Tax Information via e-mail.


Confidential data will be encrypted though the use of digital certificates. Communication between your browser (e.g. Internet Explorer) and our servers that involves any personal or confidential data uses Secure Sockets Layer (SSL) technology.

Data Collected

Information obtained from the customer will include data necessary to authenticate the customer’s identification and/or data provided by the customer to complete the necessary online activity. In addition, a limited amount of data will be collected to improve marketing and to assist in technical support of the site. This will include the Internet Protocol (IP) number and domain name from where you are accessing, the date and time of the transaction, and the site referring you to the Department's site.


No persistent cookies are saved on your computer. The Department does, however, use "non-persistent cookies" to move data from page to page where necessary in some of our online applications. This is done in a secure environment and all such "cookies" or "session values" are destroyed when the taxpayer exits the application. If an authenticated customer does not use the browser for a prolonged amount of time, such session values are also destroyed to protect the customer’s privacy.

Information Access

Information provided by taxpayers is subject to the same controls and uses as collected by government offices when a person visits an office in person or provides information via regular mail. Information is subject to statutory provisions of chapter 22 of the Iowa Code, which is the public record law. The confidentiality statutes of state and federal law also apply.

Privacy Policies of Other Sites

Various commercial websites to which you link from the Department’s site may contain different privacy practices that are not subject to chapter 22 of the Iowa Code. Visitors to these sites may wish to review the relevant privacy statements before providing personal or confidential information.
