How to make an account on the HMRC App
Download the free HMRC app from the App Store for iOS if you’re using an iPhone or the Google Play Store for Android phone users.
Follow the instructions on screen to complete your app settings. You’ll then be asked to sign into your account.
You need to know your Government Gateway user ID and password to sign into your
account on the app for the first time.
If you don’t already have an ID and password, this can be created on the same sign-in page. Once this is set up, you won’t be prompted to sign in with your ID or password again. You can log in using a pin, fingerprint or facial recognition, depending on what your device supports.
