HMRC's extra support service

HMRC’s extra support service is a small team of specially trained telephone advisers who can spend more time with vulnerable individuals and so offer a more personalised service. The team do not follow scripts rigidly. They also join things up with other parts of HMRC, so that you do not have to.

When you can use the extra support service

If you can’t understand what you are being told by HMRC or are struggling to deal with some paperwork or resolve an issue with them, the extra support service may be able to assist.

This may be because of difficulties speaking English, bereavement, a mental health issue, a learning disability, illness, or because an issue has got out of hand and you just don’t know where to turn.

You can read more about the extra support team in this HMRC publication.

What the extra support service can help with

The extra support team work on a holistic basis, considering all your affairs and have the ability to join things up with other parts of HMRC so you don’t have to. This means that solving a problem in one area should not leave another issue festering in the background. They will take ownership of queries, keep you updated and educate you to self-serve next time.

The extra support team can help with:

  • Income tax and PAYE
  • Self assessment
  • Tax credits
  • National Insurance
  • Tax debt
  • Inheritance tax
  • Child benefit
  • VAT
  • Corporation tax
  • Construction industry scheme (CIS)
  • Employers’ queries

A typical example of the type of work the extra support team do can be seen by looking at the case of Joyce.

Example – Extra support for a taxpayer with limited English

Joyce is a cleaner from Portugal. She has limited English and is unfamiliar with the UK tax system.

With the help of a friend, she registered as self-employed in 2021/22. Her 2021/22 tax return was submitted a few days late – her mother had been taken ill and she was back home in Portugal at the time of the deadline. Joyce submitted her 2022/23 tax return herself, on time – her earnings were below the personal allowance so it was quite simple. Joyce stopped working as a cleaner in 2023/24 but forgot to tell HMRC, so they continued to send her tax returns to complete, all of which are still outstanding.

Joyce contacts the extra support team and they help her make a late filing penalty appeal for the 2021/22 tax year as she had a ‘reasonable excuse’ for not filing her tax return on time. They help her complete her 2023/24 tax return – the tax return for the year of cessation. They withdraw the requirement for her to file the subsequent tax returns as she was not actually self-employed in those years. If Joyce has an amount of tax to pay for 2023/24 and she can’t pay it, HMRC’s debt management team will discuss with her how it might be paid (more on this below under the heading If you have tax debt).

HMRC’s extra support team can only really help with basic issues such as the ones in the above example and things like:

  • Tax code issues/changes
  • Completion of forms (including straightforward tax returns – more on this below) where the client has all the information/there is no question over whether tax return due
  • Needing information such as employment history or account balance
  • Telling HMRC information – ‘I have ceased self-employment etc’…

HMRC's extra support team may not be able to help if calculations are needed, if the case is complex/long running, if you are in dispute with HMRC and need independent advice (for example, appealing late filing penalty) or if previous contacts with HMRC have not solved the issue. In these instances, you should seek professional help, including from the tax charities.

Tax returns

HMRC have confirmed the following to us about what the extra support team can do to help with tax returns:

  • If a customer needs to complete a paper tax return we will take the numbers, put them in the boxes and send the return back to the customer to sign.
  • If the customer is filing online, we will not enter the figures for them, but we will try to guide them to do it themselves. At no point will we complete an online return for them, no matter how simple.
  • If the return is not necessary – such as a nil return - we can create a nil return charge to cancel the issued return and remove the customer from SA (self assessment).

Therefore, if you need help with a tax return from the extra support team, this will have to be via a paper return. If you have missed the paper filing deadline, the extra support team will consider whether it is possible to cancel any late filing penalties.

If you have tax debt

HMRC want to help if you have tax debt that you are struggling to pay. If you feel you need extra support from HMRC with tax debt issues, in the first instance, you should contact the debt management team, using the contact details you have on the letter sent to you. If you haven’t received a letter from debt management yet, use the general number for payment problems found on GOV.UK.

Make sure you understand how the debt is made up and that your tax affairs are fully up to date so that HMRC are trying to collect the correct amount of tax. If you do not think the amount of debt is correct and/or you have lots of tax issues outstanding, you should make this very clear to the debt management team.

The debt management team have been given instructions on how to deal with taxpayers who need extra help because of health conditions or vulnerability, which you can read on GOV.UK. You need to explain your personal circumstances to the debt management team so that they can take appropriate action. This might be to try and help you themselves or to pass you to the extra support team.

Example – tax debt in extra support cases

Mary has a chronic health condition and gets behind with her tax returns for several years. She receives help from the extra support team to bring her tax affairs up to date and identify how much she needs to pay HMRC going back all relevant years – this is her tax debt. Mary may be able to pay this outright or arrange a payment plan with HMRC’s debt management section.

In rare circumstances, HMRC may decide not to pursue payment of tax. This is sometimes known as remission. The tax is not permanently written off, but you will not receive further demands unless your circumstances improve unexpectedly. Remission is most common in the case of a person who is elderly, sick or long-term unemployed, and has no assets and lives in rented accommodation.

If necessary, Mary can ask the debt management section to refer her case back to the extra support team so that the special advisers can help her with the ‘payment’ aspects of her case. If the extra support team arrange remission of the debt, then Mary should be aware that her case will be reviewed periodically for any change of circumstances (either by the extra support team or the debt management section). 

If you are having a compliance check

HMRC sometimes check people’s tax position. This is known as a compliance check.

The HMRC compliance team follow the extra support principles and have access to extra support advisers to guide them around how best they can support any taxpayers they are checking.

HMRC’s guidance explains the compliance check process and explains the help you can get during and after the check. You can find the help and support page on GOV.UK.

How to contact the extra support service

There is not a separate phone number for the service. You can access the extra support team via the ordinary HMRC helplines – you should tell the telephone adviser about any special circumstances that may be affecting you on either a temporary or permanent basis, in order that they can put you through to extra support team.

The helpline advisers decide, based on their contact with you, whether they need to hand you over to the extra support team. If so, this should be a warm handover to the extra support team so that you do not have to explain your circumstances again.

You should not be afraid to ask to be transferred to the extra support team or to speak to a supervisor or manager if you do not feel the adviser understands what you are saying about your circumstances and needs.

Some people can also get help from extra support team using webchat.

The extra support team can sometimes hold face-to-face appointments, with advisers based across the whole UK. This could include a face-to-face visit at a specified venue near to home or possibly in your home if you are unable to travel.

Taxpayers can use an online form on GOV.UK to arrange a face-to-face appointment if they find it difficult to use a telephone (not limited to those who are deaf, hard of hearing or with speech impairments).

Normally, though, the extra support team will try to deal with queries over the phone as much as possible.

If HMRC really can’t help and you are on a low income then the two tax charities – Tax Help for Older People and TaxAid, may be able to help in appropriate circumstances.
