We support clients through all types of enquiries, whether routine or in-depth, including compliance checks, discovery assessments, and return-based investigations.
If you have received a letter under Code of Practice 8 or 9, it is important to act quickly. These are serious fraud-related investigations and early advice is essential. We can guide you through the process with discretion and care.
Nudge letters are now a common tool used by HMRC to prompt disclosure or clarification without formally opening an enquiry. If you receive a nudge letter, we can assess your position and help you respond accurately.Â
