Digital Certificates
The New York State Department of Taxation and Finance (hereinafter “DTF”) takes taxpayer information confidentiality and computer security very seriously. DTF’s Web site uses industry standard security measures. We also employ the use of digital certificates on our Web site to provide a secure, encrypted connection between capable Web browsers and our Web servers. This secure, encrypted connection is required by our servers whenever and wherever you are asked to enter information that may be considered confidential.

DTF maintains a number of secure applications on multiple servers. All use the domain name "nystax.gov", but each server is individually identified within the URL by a unique prefix (for example: www7.nystax.gov and www8.nystax.gov). Each secure server maintains its own digital certificate obtained from a certification authority. DTF's secure applications also display the certification authority's logo on their pages. Clicking on the logo will display information which will validate that you have reached a secure DTF server.

The page you are currently viewing also resides on one of DTF's secure servers. By clicking on the certification authority's logo to the left, you can view a working example of this functionality.

Please note that DTF is currently transitioning our certificates from one certification authority (VeriSign) to another (Entrust). As a result, until the transition is completed, you may encounter both types of certificates on our web pages.
