HMRC Inquiries, Audits & COP9 Investigation Defense

An HMRC inquiry is stressful, time-consuming, and carries severe financial penalties if mishandled. We step directly between you and HMRC, managing all correspondence and shielding you from direct inspector contact.

Levels of HMRC Investigation We Defend

HMRC checks range from routine aspect verification to serious fraud investigations under the Fraud Investigation Service (FIS). Our chartered dispute specialists handle all tiers:

Routine Compliance

Section 9A & Sch 18 Checks

Formal statutory inquiries into personal Self-Assessment (s9A TMA 1970) or company returns (Sch 18 FA 1998). We restrict HMRC's information notices to strictly relevant documentation.

Complex Avoidance

Code of Practice 8 (COP8)

Inquiries into bespoke commercial structures, offshore trusts, or marketed arrangements where HMRC suspects aggressive tax avoidance without criminal intent.

Suspected Fraud

Code of Practice 9 (COP9)

Contractual Disclosure Facility (CDF) where HMRC suspects deliberate tax irregularities. Acceptance grants statutory immunity from criminal prosecution in exchange for a full disclosure report.

Resolution & Appeals

Alternative Dispute Resolution (ADR)

Independent mediation with HMRC facilitators to break deadlocks, resolve statutory disagreements, and prevent costly First-tier Tribunal tax litigation.

Penalty Mitigation & The 60-Day COP9 Window

If you receive a COP9 letter from HMRC Fraud Investigation Service, you have exactly 60 days to decide whether to accept the Contractual Disclosure Facility. Rejecting or ignoring the letter frequently triggers criminal proceedings.

We represent you from day one, preparing comprehensive technical disclosure reports and demonstrating "telling, helping, and giving access" to reduce potential statutory penalties from 100%+ down to the minimum statutory limits.

Strictly Confidential Review

Speak with our senior dispute partner. All discussions are conducted under strict client confidentiality.
