Information agents need when contacting HMRC

Agent phoning HMRC

Five questions have to be answered correctly.

Initial questions will be asked that relate to the agent and could include:

  1. Agent's (caller's) name.
  2. Name of the practice.
  3. The address of the practice.
  4. The agent reference number.

Additional questions will relate to the client and could include:

  1. Name.
  2. Address of the client, and if applicable of the business.
  3. Client's UTR.
  4. Client's National Insurance number.
HMRC phoning agent

The agent is entitled to ask questions of the HMRC staff to establish that they are indeed who they say they are.

The questions that HMRC staff are authorised to answer include:

  1. Date and time of an earlier call when the agent contacted HMRC regarding that client.
  2. Date of issue of an SA assessment, or any other HMRC document issued regularly.
  3. Name of the HMRC staff member.
  4. A verifiable telephone number from which HMRC is phoning.

Where an agent requests a call back for a self assessment or PAYE issue that cannot be dealt with during their initial call to HMRC, HMRC will take a password from the agent to be quoted by the HMRC officer who makes the call back. The password will be for that call only.

Unsolicited self assessment and PAYE calls may be made by HMRC if there is a need to discuss correspondence recently received by HMRC. Callers will offer reference to earlier correspondence or phone calls as proof of identity.

HMRC has developed a process for unsolicited calls from Debt Management and Banking (DMB) and VAT departments when an agent requires proof that the call is genuinely from HMRC. DMB can be asked to quote two characters from the agent reference number. They also make reference to earlier contacts or information held. VAT will quote the four digit ID as an extra assurance. Callers will also offer a call back should the agent remain concerned.

Business by telephone

When an agent or taxpayer phones HMRC they should take detailed notes so that these can be referred to in the event of a dispute. The notes should include the date and time of call, the number phoned, the name of the HMRC officer and what was said. VAT staff can provide a reference number. This can make the difference between winning (Abdul Noor v HMRC [2011] UKFTT 349 (TC)) and losing (R (Corkteck Ltd) v HMRC [2009] EWHC 785) a case.

HMRC has withdrawn its previous guidance on which matters can be dealt with over the phone and which need to be in writing. HMRC’s Once and Done initiative means that it is making changes to reduce the need for taxpayers and agents to write and transactions are also being moved online. We have asked HMRC to consider providing revised guidance.

HMRC online contact

There is no generally available facility to contact HMRC by email but it is possible to use structured or standard email, webchat and online forms for specific types of transactions and contact. HMRC is developing digital services at a fairly significant rate and the information shown below is likely to change very frequently.

We have included below only those services which are available to agents – there are additional services available to taxpayers and claimants through their digital tax account. HMRC does intend to roll out additional services to agents but this is likely to be through commercial software.

The facilities that are available to agents are:

Structured emails
Email addresses

phishing@hmrc.gsi.gov.uk to report fraudulent emails and text messages (see guides).

customs.hotline@hmrc.gsi.gov.uk to report customs, excise and VAT fraud.

ir35@hmrc.gov.uk for IR35 queries.

exitsteam.counteravoidance@hmrc.gsi.gov.uk to exit from a tax avoidance scheme.

mailbox.sdrt@hmrc.gsi.gov.uk for stamp duty reserve tax queries.

optiontotaxnationalunit@hmrc.gsi.gov.uk for queries on opting to tax properties.

MLRCIT@hmtc.gsi.gov.uk for money laundering related queries for registered businesses.

ncts.helpdesk@hmrc.gsi.gov.uk new computerised transit system(NCTS) helpdesk.

ecs.helpdesk@hmrc.gsi.gov.uk export control (ECS) helpdesk.

ics.helpdesk@hmrc.gsi.gov.uk import control system (ICS) helpdesk.

emcs.helpdesk@hmrc.gsi.gov.uk excise movement and control system helpdesk.

Some parts of HMRC’s business (such as specialist units and compliance offices) do correspond with taxpayers and agents by email – this should only happen with prior consent and a formal acceptance of the risks. Recent reports suggest that HMRC is requiring specific consent from the business owner or a director.

HMRC has made available a number of webchat facilities which are for general queries only ie, they are not secure and personal details should not be exchanged. There is a secure webchat facility available to agents using the beta service for PAYE liabilities and payments.
HMRC forms

HMRC has a large collection of forms. These fall into a number of categories:

  • Traditional paper forms that are printed, completed and posted to HMRC for processing.
  • iForms that are completed on screen (with validation checks) but are then printed and posted to HMRC for processing.
  • iForms that are completed on screen but can be submitted online. In most cases the forms can be submitted online only by the taxpayer but in February 2017 HMRC started to allow for agents to submit certain iForms online on behalf of clients. The first batch of such forms is:

HMRC postal contact

HMRC is encouraging telephone and email contact using i forms. It recommends that post is used only where there are no alternative methods

Frequently used addresses

HMRC has consolidated its postal hubs in recent years and it increasingly scans mail. Replies to HMRC correspondence should be addressed to the address on that particular correspondence.

Tips on making your letters work

To enable post to be dealt with as speedily as possible the following is recommended:

  • No paperclips, but staples and tags are OK, if just one is placed at the top left-hand corner.
  • Place any cheques on top, but if there are no cheques attached the letter should be on top. Remember to also include the tax reference on the cheque.
  • Reference numbers should be clearly marked, particularly if the item relates to a corporation tax or compliance issue.
  • Agents give their full name, address, telephone number and client name and reference number and also indicate whether authorisation from the client through a 64-8 or online is in place.
  • Special deliveries are accepted and although the receipt is more secure they take longer to process, as they are opened by a separate team.
Use standard headings for post

HMRC has created a list of standard headings that agents can use when writing about their clients’ self assessment and PAYE. Using these standard headings should speed up post processing and ensure that the item is directed to the correct area within HMRC. The primary headings summarise the broad subject of the letter, while the secondary headings can be used where the matter is more specific or requires more technical input.

These headings are:

Primary Secondary
Agent no longer acting Appeals - penalty appeals
Allowances and reliefs Appeals - supercharge appeals
Calculation queries Capital allowances
Cessation of a source of income Capital gains (including Principal Private Residence Elections and quoted shares)
Complaints Chargeable events
Deceased case/bereavement Discovery assessments
Employer correspondence Double Taxation Relief
Employer penalty appeal Film losses
ESCA19 claim or employer error Foreign income (Foreign Tax Credit)
Information request Investment club
Insolvency/bankruptcy Trading losses
Loss claims

Overpayment relief under Schedule 1AB

New source of income Scholarships/grants
PAYE coding query/amendment Share Schemes
Progress chasing correspondence/repayments Special assessments
Self Assessment appeal Venture Capital Trust/Enterprise Investment Scheme
Self Assessment/PAYE repayment claim
Self Assessment set up or close record
Self Assessment statement query
Self Assessment tax return amendment
Self Assessment tax return request
Agent account manager (AAM) service

If an agent has a client specific problem and has exhausted all other avenues, then they may approach an AAM, who will endeavour to resolve their problem. The service covers all areas of taxation. More details are available at Agent Account Manager service

Access to this service is via a structured enquiry form on the HMRC website. An agent must first register for the service by submitting the AAM user registration form. Subsequently an Issue Resolution service form must be completed for the specific issue and submitted to HMRC.
