TCRM1000 - Executive summary
This guidance is for LBS customers and LBS staff involved in customer-facing work and explains HMRC’s approach to working with large business customers to manage their tax compliance risk. The key elements of this approach are:
- to build and maintain effective relationships with all our customers;
- to classify our customers as Low Risk or not Low Risk so that we can target our resources on those customers who represent the greatest risk; and
- for those customers who are not Low Risk, to understand in what respects they are not Low Risk so that we can target our resources on these areas.
We decide a customer’s overall level of tax compliance risk by first considering the inherent risk they represent (in terms of, for example, their size, complexity and the amount of change they are subject to) and then looking at whether or not they effectively mitigate this risk through their behaviour (for example, their attitude to tax avoidance, their systems and processes and their openness with HMRC). This is done during the periodic Business Risk Review, which is a collaborative process between the customer and HMRC. With the right behaviour any customer, regardless of their size or complexity, can benefit from Low Risk status.
The following provides an overview of the Executive summary.

We assess customers’ behaviour against three factors, each with a number of criteria which are set out below. If a customer meets all these criteria in all material respects we will classify them as Low Risk.
In order to be classified as Low Risk a large business customer will:Governance

If we identify a customer as Low Risk they can expect that, in general, they will set the agenda for our interactions with them and that they will have more certainty over their tax position because we will generally trust their tax analysis. We will not normally carry out another Business Risk Review for three years and in the interim will not challenge their tax returns or declarations. However, we will maintain sufficient contact with them to ensure that our knowledge of their business is up-to-date. This will enable us to provide them with a good standard of service and to ensure that both parties are kept informed of emerging significant risks.
In the case of customers who are not Low Risk, we will still aim to develop and maintain an open and transparent relationship with them and to work collaboratively with them in real time to reduce their level of tax compliance risk. Working in this way helps both sides manage their resources better and provides the customer with more certainty about their tax position. In general, customers who are not Low Risk can expect us to:
- Carry out annual Business Risk Reviews;
- Carry out regular analysis (Risk Assessment) of their tax returns to identify areas of potential risk (though we will target this based on our understanding of where risk may lie developed during the BRR); and
- Carry out more regular interventions (Risk Working) to test the information we have been given.
The results of this Risk Assessment and Risk Working activity will be fed back into the Business Risk Review.
In cases where customers represent an ongoing and significant risk, we will assemble task forces of specialists to deal with the risk intensively and will engage at Board level to persuade that customer to change the behaviours that are generating those risks.
