With our decades of experience, you can be confident you've hired the right team.

Gather

We start by gathering key information in line with how HMRC approach their status enquiries.

We will focus on areas of strength and weakness with drill down into material areas, based on arguments HMRC currently use in tax tribunals.

Evaluate

A detailed evaluation process is conducted, based on the facts and current case law.

This helps identify any determinations that may be subject to challenge, how they might be challenged and if reasonable care has been taken.

Recommend

We will provide you with a detailed report using a risk-based approach, clearly identifying areas of strength and weakness.

Our recommendations will help you strengthen your compliance activity and maximise the chances of early closure of any compliance check.
