Privacy Policy


The Department of Revenue (DOR) fully supports the protection of individual privacy and minimizes the collection of personally identifiable information to the least amount of information required to complete a particular transaction. "Personally identifiable information" is information about an individual or business that could be used to identify that person or business. Examples of personal information include an individual’s first and last name, residential address, telephone number, Social Security number, a business’s account number, driver license number, and e-mail addresses.

The Privacy Policy covers the following topics:

  1. Collection and Use of Personally Identifiable Information
  2. Public Records
  3. Cookies
  4. Security
  5. Web Site Disclaimer
  6. Contact Information

1. Collection and Use of Personally Identifiable Information

The Department of Revenue may collect some personally identifiable information about individuals who visit our Web site. This information may include:

The information collected or stored is used to improve the content of our Web services and to help us understand how the public is using these services. In addition, we use an IP address to direct Internet traffic as well as to provide protection for this information.

It is also our policy not to engage in "online profiling," the practice of aggregating information about consumers preferences and interests, gathered primarily by tracking their movements online, and using the resulting consumer profiles to create targeted content on Web sites.

If an e-mail message is sent to use during a visit to our site, the following information will be collected:

This information is collected to ensure an appropriate response. For example, this information may be needed to address issues identified, to make improvements to our Web site, or to forward an e-mail message to another agency for appropriate action. E-mail addresses obtained in this manner will not be sold or given to private companies for marketing purposes.

It is our policy not to collect any personally identifiable information unless that information is required to complete a particular transaction. In addition, we do not collect personally identifiable information unless a user voluntarily participates in services that ask for that information. For example, choosing not to participate in these services will not affect the ability to use any other features of our Web site.

Individuals choosing to "opt-in" specific services, such as being automatically provided informational updates via e-mail, can remove themselves from such services at any time. Opting-in for one service does not constitute opting-in for all services.

Personally identifiable information shall not include information collected in furtherance of any regulatory, investigative, or criminal justice purpose; information collected in furtherance of litigation in which the state is a party; or information that is required to be collected pursuant to any state or federal statute or regulation.

2. Public Records

The state’s Open Records Act is applicable to this Privacy Policy pursuant to the Colorado Revised Statutes, Title 24, Article 72, Part 2, which states: "It is declared to be the public policy of this state that all public records shall be open for inspection by any person at reasonable times, except as provided in this part 2 or as otherwise specifically provided by law."

If personal information is requested on the Web site or is volunteered by the user, state and federal law may protect that information. However, all information becomes a public record and may be subject to public inspection and copying if not protected by federal or state law.

Furthermore, the information contained in many kinds of documents filed with the Department of Revenue (DOR) or electronically stored and may be made accessible to the public through the DOR Web site.

Users are cautioned that the collection of personal information requested from or volunteered by children online or by e-mail will be treated the same as information provided by an adult and may be subject to public access.

3. Cookies

To better serve our uses, we may use "cookies" to customize your browsing experience with us. Cookies are simple text files stored on a computer by the Web browser. Cookies provide a method of distinguishing among visitors to our Web site.

Cookies created on a computer by using this Web site do not contain personally identifiable information and do not compromise privacy or security. The cookie feature is used only to store a randomly generated identifying tag on a computer. A cookie file can be refused or deleted from a computer by using widely available browser options or security software. Our services are provided in such a way that the use of cookies is not mandatory.

4. Security

The Department of Revenue (DOR) has taken several steps to safeguard the integrity of its computing infrastructure, including but not limited to authentication (ensuring that user names and passwords provide appropriate access), monitoring site performance, and auditing network transactions. Security measures have been integrated into the design, implementation, and day-to-day practices of the entire operating environment as part of a continuing commitment to risk management.

In the case of credit card transactions, tax filings and account information, for protection and peace of mind, the Department of Revenue’s Web site uses the most up-to-date secure socket layer (SSL) technology for transmitting this information over the Internet. We also authenticate our site by using VeriSign(TM) Secure Server Digital ID. This is added assurance that we are who we say we are. All pages that request credit card and other confidential information are encrypted with SSL security.

5. Web Site Disclaimer

The Department of Revenue’s (DOR) Web site contains links to other Web sites, including Web sites operated by other government agencies, nonprofit organizations, and private businesses. When a user chooses a link from the DOR Web site to another Web site, he/she leaves our site and therefore, this Privacy Policy will no longer apply. When linking to another Web site, uses are subject to the privacy policy of that Web site.

DOR does not endorse any particular viewpoint that appears on any Web page that may be linked from our Web site. All forms of advertising are also prohibited on our Web site.

If objectionable material on these pages or in any linked page is encountered, please notify DOR by e-mail at edo@spike.dor.state.co.us.

Neither DOR nor any employee of the State of Colorado (1) warrants the accuracy, reliability, or timeliness or any information published by this system or (2) endorses any content, viewpoints, products, or services linked from this system. Neither DOR nor any employee of the State of Colorado shall be held liable for any losses caused by reliance on the accuracy, reliability, or timeliness of such information. Portions of such information may be incorrect or obsolete. Any person or entity that relies on any information obtained from this system does so at his or her own risk.
