TLS Support

Protecting your data is important to us. As part of our ongoing efforts to safeguard your data, on September 30, 2018, we will be upgrading Hawaii Tax Online ( security to require TLS 1.2 or higher. TLS (or “Transport Layer Security”) is one of several security protocols used to securely transmit data on the internet.

Most browsers updated after 2014 will support TLS 1.2. Please use the following browser versions (or higher): Safari 7, Android 5.0, Firefox 27, Chrome 30, and Internet Explorer (IE) 11.

Most users will not notice the change, especially if you regularly update your web browser software. As of July 1, 2018, major credit card companies, online retailers, web browsers, web applications, and service providers have already ended their support of the earlier and less secure SSL and TLS 1.0 standards. In the coming months, your web browser may begin to warn you about potential security problems with websites that still rely on SSL or TLS 1.0.

Some older web browsers and versions of the iOS and Android operating systems that do not support TLS 1.2 will no longer be able to connect to the Hawaii Tax Online website. You will need to update your web browser to continue to use Hawaii Tax Online.
