A challenge from HMRC is often distressing and it is important to appoint an experienced professional who is familiar with how HMRC work to handle the dispute and achieve the right outcome.  Tax enquiries and disputes can take years to resolve and are potentially costly both in terms of professional fees and the ultimate monetary settlement of tax, interest and penalties.
