    Technical requirements for batch filing

    • Internet Explorer is the only browser that is fully compatible with this procedure. Therefore, if you are using a different operating system to Windows, or a different browser, we recommend that you file individual tax returns or use a PC. The incompatibility of browsers such as Google Chrome or Mozilla Firefox is due to the fact that the procedure requires Java, and these browsers are no longer supporting the technology required for Java applets.
    • Make sure that you have an electronic certificate installed in your browser, issued by a certifying body that is recognised by the Spanish Tax Agency and authorised for filing declarations on behalf of third parties.
    • Ensure that you have the latest version of Java installed on your computer. You can follow the help instructions for installing Java in Windows in the following link:
