HMRC tax investigations are becoming more frequent — and they can affect anyone: businesses, directors, or individual taxpayers. Even if no errors are found, the process can be lengthy and costly.

At Marsal Accountants, we offer a dedicated Tax Investigation Service that covers the cost of our work during an enquiry. With client-facing hours of experience, we guide you through the process calmly and professionally — helping you respond effectively and resolve matters quickly.

Types of Tax Enquiries We Handle

We support clients through all levels of HMRC enquiries, including:

• Random checks on Self-Assessment Tax Returns
• Investigations into offshore assets and income
• Full business reviews and operational audits
• Code of Practice 9 (COP9) and criminal investigations

We understand the stress these enquiries can cause — some lasting over two years. We'll be by your side throughout, offering clear advice and full support.

Tax Investigation Fees

We offer fixed fees for our work — agreed in advance before we begin. No surprises, just clarity and confidence.
