Government Gateway SSLv3

30 September 2016

On 30 September 2015, HMRC made a change so that if you were using the SSLv3 protocol to connect to their services you were no longer able to. For the majority of online customers this meant no change as they were already using a more secure protocol (such as TLS1.0, TLS1.1 or TLS1.2) by default.

Government Gateway will be disabling SSLv3 on a permanent basis on 10 October 2016.

If you’re uncertain about the type of secure connection your browser or other software can support, you can check it at Your SSL client is Bad and other similar services.

If you’re still using the SSLv3 protocol it is advised that you use a more secure protocol to connect to Government Gateway.
