​​Browser Security

To protect the privacy and confidentiality of our customers, the Florida Department of Revenue has raised its standards for securing communication between web browsers and its interactive websites (e.g., Registration, e-Services Enrollment, File and Pay, Child Support Services for Employers, and Child Support eServices).

Browser Restrictions

If you are using an older version of a web browser, you may be blocked from logging into Department of Revenue interactive websites. The Department restricts access to web browsers that utilize Transport Layer Security (TLS) versions 1.1 and 1.2. The latest versions of common web browsers support TLS. Users who are blocked must update their browser before they can interact with certain Department websites.

Why update your browser?

You should always keep your browser updated. Your browser's publisher provides periodic updates as issues arise or new security features are developed. Security updates patch vulnerabilities that may be exploited by malware, helping to keep users and their data secure. Regular security updates help protect computers from malicious attacks, so upgrading your browser and staying current is important. Keeping your browser updated ensures a safer, more productive interactive experience.

What browsers are acceptable and how do I update?

For optimized performance and security, you must use a browser that utilizes TLS 1.1 and TLS 1.2. The latest versions of the most common browsers, listed below, utilize TLS 1.1 and 1.2, and are acceptable for use with Department websites:
