You can get help from HMRC if you have a tax issue and:

• cannot find the information you need on GOV.UK
• there is not a dedicated team in HMRC that you can contact for help

The Mid-sized Business Customer Compliance Resolution Team will help deal with your query or will direct you to someone who can.

You, or your agent, can also request a temporary Customer Compliance Manager (tCCM) if your business has complex tax affairs. They act as a direct contact to HMRC and specialists to help you with tax issues that are affecting your business.

They can help if you:

• are going through a business cycle event
• are experiencing a period of significant growth
• have multiple open tax enquiries
• have multiple complex tax issues
• have a significant volume of contact with HMRC

If you’re a mid-sized business experiencing growth, you may be able to get additional support for growing businesses.

Who can use this service

This service can be used by any mid-sized business with either:

• a UK turnover above £10 million
• at least 20 employees

Agents can also use this service on behalf of their mid-sized business clients.

How to apply

You’ll need:

• your own (company or agent) Government Gateway user ID and password — if you do not have one, you can create one when you apply
• contact details of the business — including name, telephone number and correspondence address
• the business’s Unique Taxpayer Reference (UTR), VAT registration number or employer PAYE reference
• details of the business’s annual turnover and number of employees
• contact details of your agent or representative (if applicable)

You can provide up to 10 documents to support your application. They’ll need to be 15MB or less each and in a commonly used format such as PDF, JPEG or DOCX.

Apply

You can apply for help from the Mid-sized Business Customer Compliance Resolution Team or request a temporary Customer Compliance Manager.

If your question cannot be answered through GOV.UK content or by contacting a dedicated team in HMRC, we’ll appoint someone to help you with your query.
