They also guide clients on potential time-limiting provisions, which can sometimes reduce the period for which HMRC can assess additional tax. These strategies require in-depth knowledge of HMRC manuals, tribunal precedents, and practical experience dealing with compliance officers—a level of expertise that most taxpayers lack.
