HMRC Tax Dispute Lawyers

Got a tax dispute with HMRC?

Our ex-HMRC specialist tax lawyers can be instructed to assist you to resolve your dispute. They will deploy their decades of first-class experience in handling and carefully managing HMRC whilst guiding you on complex tax legislation and strategising to get you the best possible result. It’s important for individuals and businesses facing tax disputes to seek professional advice in order to navigate the complexities of tax law and procedures.

What is a Tax Dispute?

A UK tax dispute is a disagreement between a taxpayer and the tax authority (HM Revenue and Customs – HMRC) regarding the interpretation or application of tax laws. This can arise due to differences in the calculation of taxable income, disputes over allowable deductions, or the application of tax credits, or disagreements about the overall tax liability.

Tax disputes can occur at different stages of the tax process, including during the filing of tax returns, during tax audits or investigations by HMRC, or even during the appeals process if the taxpayer disagrees with an assessment or decision made by the tax authorities. When a tax dispute arises, it’s common to instruct professionals to engage in discussions with HMRC to resolve the issue.

Unlike a solicitor who by law must provide an entirely confidential legal service, an accountant has no legal duty of confidentiality and will have little to no skill in managing tax litigation; we have seen numerous cases where an accountant has disclosed material that we as solicitors would not be able to disclose and also worsened the client’s position with HMRC. Our team of ex-HMRC barristers and solicitors can carefully manage tax disputes by reviewing and providing additional documentation, clarifying positions, or negotiating a settlement with HMRC. In some cases, taxpayers may appeal decisions to independent tax tribunals or courts if an agreement cannot be reached through negotiation. Alternative dispute resolution mechanisms, such as HMRC mediation, may be explored as a way to resolve conflicts outside of formal legal proceedings.

Don’t risk using an accountant against HMRC…

It is important to note that all client communications to accountants are not legally privileged and are easy for HMRC to obtain; however, communications to lawyers are legally privileged and highly confidential. Therefore it is beneficial to the success of many of our clients’ cases that we be instructed to instruct an experienced forensic accountant on your behalf.

Although you may have instructed an accountant in relation to your accounts and tax matters for yourself or your business, in most cases your accountant should realistically only assist you in tax compliance matters whereas we specialise in assisting you in relation to any investigations that HMRC have brought against you. We regularly work with accountants to ensure that collectively we are able to obtain the best possible resolution to your matter.
