How HMRC keeps you safe online

HMRC takes online security very seriously. Here are just some of the measures they take to protect you and your data.

Firewall protection

HMRC uses firewall protection as a very effective high security barrier around its systems and your data. This detects any attempts at unauthorised entry.

Security certificates

Any page of the HMRC website that contains sensitive information is protected by a technology known as SSL (Secure Sockets Layer). This encrypts the data you send to HMRC via the Internet. When you log in to HMRC's Online Services you are always protected - and this is shown by the padlock in the bottom right hand corner of your Internet browser.

Secure sign-in

HMRC's Online Services are only available to customers who register their details. Every time you log in, you must enter your User ID and Password before you can access your services.

Time-out

After 15 minutes of inactivity within HMRC's Online Services, you're automatically logged out. So if you've forgotten to log out, no one will be able to access your services in your absence. Simply log in again to continue. It's good practice to always log out if you are leaving your computer unattended to prevent unauthorised access. When finally leaving the HMRC website, it is good practice to close your Internet browser.

Further measures

HMRC will continue to monitor its security measures and update and enhance them as necessary.
