Our approach

How we deliver tax investigation service

01

Immediate response management

As soon as you receive HMRC correspondence, we take over the communication. We review the scope of the enquiry, assess what is being asked and formulate the appropriate response strategy before any reply is sent.

02

Evidence gathering and position preparation

We work through the records methodically, gather the evidence that supports your position, identify any issues that need to be addressed proactively and prepare a clear, organised response that reduces the scope for HMRC to widen the enquiry.

03

Negotiation and resolution

We manage the negotiation with HMRC, respond to follow up requests and where a settlement is required, negotiate the best outcome the facts will support, minimising penalties and interest where the circumstances allow.

Common questions

Frequently asked questions

What types of enquiry does HMRC open?

HMRC can open aspect enquiries focused on a specific entry in a return or full enquiries, which examine the entire return. They also open compliance visits and written enquiries for VAT and employer taxes. For more serious investigations, HMRC uses code of practice procedures. We deal with all types.

Should I respond to HMRC directly?

You have the right to respond yourself, but it is rarely advisable. HMRC enquiry officers are trained to expand the scope of an enquiry where responses are incomplete, inconsistent or invite further questions. A professional response, carefully prepared, keeps the enquiry focused on what was originally raised.

How long does an HMRC enquiry take to resolve?

A simple aspect enquiry can be resolved in two to four months with a well prepared response. Full enquiries typically take six to eighteen months. The timeline depends on the complexity of the issues, HMRC's workload and how promptly responses are provided. We manage the pace of the process as far as possible.

What are the penalties if HMRC finds an error?

Penalties for tax errors range from 0% to 200% of the unpaid tax depending on the behaviour involved careless, deliberate or deliberate and concealed and whether disclosure was prompted or unprompted. We work to demonstrate that any errors were careless rather than deliberate, and that disclosure was as full as possible, to minimise the penalty percentage applied.
