Why choose us

Careful tax advice where the right answer matters

HMRC investigation work should not be approached as a negotiation based on fear, or as a simple exercise in accepting whatever HMRC asks for. Each case has its own facts, documents, tax rules and merits. Our role is to help establish the correct tax position and present it properly.

Our view

Pay the correct tax, not simply what is demanded

HMRC has important powers, but those powers still operate within tax law, evidence and procedure. A taxpayer should not ignore HMRC, but equally should not accept an assessment, penalty or conclusion without checking whether it is correct. We approach cases by identifying the legal basis, testing the figures and considering whether the evidence supports HMRC’s position.

We do not promise outcomes

Investigation work depends on the documents, facts and conduct involved. We give practical advice based on what can be evidenced, not unrealistic assurances.

We do not create artificial positions

If tax is due, it should be calculated properly and disclosed correctly. The focus is accuracy, mitigation where available and controlled communication.

We challenge where there is a proper basis

If HMRC’s figures, assumptions, penalty behaviour or time limits appear wrong, those points should be considered carefully and raised professionally.

What makes the service different

A technical, evidence-led approach to HMRC matters

HMRC enquiries can involve tax law, accounting records, behaviour, disclosure quality, penalties, time limits and appeal rights. A proper response needs structure rather than guesswork.

Careful review

We identify the type of HMRC issue first

A compliance check, nudge letter, Schedule 36 notice, COP8, COP9, disclosure or penalty appeal each requires a different approach.

Tax position

We check the figures before responding

The tax position should be calculated and tested before explanations are sent. This helps avoid inconsistency and unnecessary admissions.

Penalty position

We consider behaviour and mitigation

Penalties often depend on care, disclosure quality, cooperation and whether the matter was prompted. These points should be evidenced properly.

Communication

We avoid vague or emotional replies

HMRC correspondence should be factual, complete where necessary and limited to the issues that need to be addressed.

Procedure

We consider powers, deadlines and rights

Some requests can be challenged, some deadlines can be managed, and some decisions may be reviewed or appealed depending on the facts.

Judgement

We keep the case proportionate

Not every HMRC issue is fraud, and not every disagreement requires escalation. The response should fit the level of risk.

Balanced representation

We are neither dismissive of HMRC nor intimidated by HMRC

The right position is usually found between two mistakes: ignoring HMRC risk on one side, and accepting unsupported conclusions on the other.

Where tax is due

We help calculate it accurately, consider the correct disclosure route, organise supporting records and deal with penalty exposure in a controlled way.

How we work

A structured process before any response is sent

In sensitive HMRC matters, the first response can shape the direction of the case. We slow the process down enough to understand the issue properly.

1

Read the HMRC letter

We identify the tax type, years, deadline, legal basis and whether the matter is routine, formal or serious.

2

Review the records

We check returns, accounts, bank records, invoices, rental schedules, foreign income records or other relevant evidence.

3

Assess the position

We consider tax due, explanations, weaknesses, penalties, disclosure options, HMRC powers and possible appeal rights.

4

Prepare the response

We help prepare a factual, structured and proportionate response based on what can be supported.

Evidence matters

Good tax advice depends on reliable records

A client’s explanation is important, but HMRC will usually expect supporting evidence. We place importance on documents, timelines, calculations and consistency because those points often affect tax, penalties and settlement discussions.

Tax returns and computations

Filed returns, schedules, amendments, working papers and calculations.

Accounts and bookkeeping

Business records, VAT records, PAYE reports, CIS returns and reconciliations.

Bank and transaction records

Statements, transfers, source of funds evidence and supporting documents.

Correspondence and timelines

HMRC letters, adviser notes, contracts, explanations and event chronology.
