Pure Tax Investigations FAQ
What is the difference between a compliance check and a tax investigation?
A compliance check is a routine review by HMRC to check the accuracy of a tax return. It is often limited in scope. A tax investigation, such as under COP8 or COP9, is far more serious and intrusive, launched when HMRC suspects significant errors, avoidance, or deliberate fraud, and can delve deeply into personal and business affairs.
When should I seek specialist help for a tax investigation?
You should seek specialist help immediately upon receiving any formal communication from HMRC indicating an enquiry or investigation. Early intervention is crucial. Specialists like Pure Tax Investigations can manage all contact, ensure you respond correctly, and prevent missteps that could escalate the situation or increase potential penalties.
What is Code of Practice 9 (COP9) and how can you help?
COP9 is an HMRC procedure used when they suspect deliberate tax fraud but are offering a chance to make a full disclosure under the Contractual Disclosure Facility (CDF) to avoid criminal prosecution. Our help is vital to navigate this high-stakes process, prepare a technically robust disclosure, and negotiate the civil monetary settlement.
Can you help with disclosures for cryptocurrency gains?
Yes. Pure Tax Investigations has specific expertise in crypto tax disclosures and enquiries. They can calculate historic gains and income from cryptocurrency transactions, advise on the correct tax treatment, and manage the disclosure process to HMRC, whether as a voluntary disclosure or in response to an enquiry.
