Need to help a relative or friend with tax? HMRC’s Trusted Helper service makes it quick and easy to support someone online. Whether it is checking Income Tax, updating their personal details or reviewing taxable benefits like company cars or medical insurance, you can do it all with their permission. After registering as a trusted helper, your friend or family member simply needs to approve your access. You can help up to five people, but remember, they remain responsible for their own tax affairs.
This online option allows you to support someone, such as a friend or relative with key tax tasks, such as checking their Income Tax, updating their personal tax account or reviewing their taxable benefits (limited to company cars and medical insurance).
To get started, you must register online as a trusted helper. Once you have signed up, the person you are helping will need to log in and approve your request. If they cannot go online, you can call HMRC on their behalf, but they must be physically present with you during the call. HMRC will confirm their identity and their consent before proceeding. You will also need their National Insurance or tax reference number.
You can help up to five people using this service. While you can assist with their tax matters the person you are helping remains legally responsible for their own tax affairs. You must sign in using your Government Gateway details, and you may be asked to verify your identity using photo ID such as a passport or driving licence.
HMRC also offers this service in Welsh and provides additional support for those with disabilities or non-English speakers.
