Before you call
This helpline may 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 already have a personal tax account, you can set one up.
Due to measures put in place to stop the spread of coronavirus (COVID-19) we have fewer advisers available to answer your calls.
Monday to Friday: 8am to 4pm
Closed on weekends and bank holidays.
