Before you call
The helpline uses speech recognition software, so you will be asked why you are calling HMRC. If you cannot use speech recognition software, find out how to get help from HMRC if you need extra support.
This helpline may also ask you some security questions. Make sure your personal details and address are up to date in your personal tax account or you could fail telephone security. If you do not have a personal tax account, you can create one before you check your details.
HMRC may ask if you want to add voice identification to your account. You can find out more in the Voice Identification Privacy Notice.
You can use Relay UK if you cannot hear or speak on the phone: dial 18001 then 0300 200 3100.
