Find out about downtime and technical issues with HMRC services.
From 30 September 2015, you will no longer be able to connect to HMRC online services using the SSLv3 protocol. For the majority of online customers this will mean no change.
The SSLv3 protocol is considered insecure and is no longer supported by many browsers. You should ensure your browser (or other software) is capable of using and configured to use ‘Transport Layer Security’ (TLS) 1.0 or above, (TLS 1.1 and 1.2).
If you are uncertain about the type of secure connection your browser or other software can support, you can check it at https://www.howsmyssl.com/ and other similar services.
