What Is Code of Practice 8?
Code of Practice 8 (COP8) is used by HMRC when they suspect serious tax avoidance — as opposed to tax fraud. While COP9 deals with deliberate fraud, COP8 covers cases where HMRC believes a taxpayer has used artificial or contrived arrangements to reduce their tax liability, but where there is no suspicion of criminal behaviour.
Receiving a COP8 notice means HMRC wants to examine whether your tax affairs include arrangements that, while not illegal, go beyond what HMRC considers acceptable tax planning.
How Does COP8 Differ from COP9?
- COP8: Targets serious tax avoidance (legal but aggressive schemes). No criminal prosecution threat.
- COP9: Targets suspected deliberate tax fraud. Comes with the threat of criminal prosecution if the CDF is not accepted.
However, if during a COP8 investigation HMRC discovers evidence of fraud, the case may be escalated to COP9.
HMRC's Powers Under COP8
Under a COP8 investigation, HMRC has extensive information-gathering powers, including:
- Requesting detailed financial records and documents
- Issuing formal information notices under Schedule 36 Finance Act 2008
- Examining arrangements involving trusts, offshore structures, or complex financial instruments
- Applying penalties for deliberate errors, failures to notify, or failures to take reasonable care
Common Areas of Focus
COP8 investigations frequently focus on:
- Marketed tax avoidance schemes (including those on HMRC's spotlight list)
- Offshore income and assets not properly disclosed
- Complex trust arrangements designed to minimise tax
- Unusual reliefs or deductions that appear disproportionate
- Employment income diverted through personal service companies
How to Respond to COP8
If you receive a COP8 notice, it is essential to respond promptly and with expert guidance. The key steps include:
- Engaging a specialist tax adviser immediately
- Reviewing all arrangements that HMRC is questioning
- Preparing a comprehensive response with supporting documentation
- Cooperating with HMRC while protecting your legal rights
- Negotiating any settlement, including penalties and interest
