HMRC Tax Appeals

HM Revenue and Customs (HMRC) have actively sought to clamp down on tax evasion or avoidance and increasingly more individuals and businesses are subject to HMRC tax penalties. It is vital that any taxpayer (individuals and businesses) deal with tax issues as soon as they occur to prevent their appeal from being time-barred and to minimise the accrual of penalty fees. 

Our London Tax Solicitors and Barristers have vast experience of tax laws and first hand commercial, litigation and advocacy experience . We have a proven track record of successfully contesting disputed tax assessments and penalties with HMRC. The tax authorities have lost many cases that are appealed through negotiation, internal review or through the Tax Tribunal.

Our team of expert Tax Solicitors and Barristers provide our clients with advice in relation to:

The following is a brief guide on how individuals or a business can protect themselves from being adversely affected by HMRC tax penalties and assessments.

The HMRC Appeal Process

If a taxpayer disagrees with HMRC, there is a 2-stage process for a taxpayer to dispute a HMRC decision:

Stage 1: give notice of appeal to HMRC. A taxpayer can appeal in writing within 30 days of HMRC’s notice of their decision. HMRC will confirm their first decision, amend their decision or agree with the taxpayer’s assessment.

Stage 2: if the taxpayer’s position cannot be agreed with HMRC in stage 1 then a taxpayer can avail themselves of two further options:

i. HMRC can offer an internal review of the disputed decision (or the taxpayer can request this procedure at any time). The review is an entirely internal procedure completed not by the original HMRC decision maker but by a different HMRC officer.

ii. A taxpayer can appeal to the First Tier Tax Tribunal if the taxpayer cannot agree their position following the review. The independent tribunal will make a determination on the case. A further appeal is permitted if a taxpayer does not agree with the decision.

Stage 1: Notice of Appeal to HMRC

If you disagree with HMRC’s assessment or penalty, then you should first send notice to appeal the decision to HMRC. If HMRC makes a tax decision against you, you can contact HM Revenue and Customs (HMRC) or professional advice should be sought. 

The first recourse of a taxpayer wishing to dispute a decision of HMRC is to examine the decision letter sent by HMRC which will contain instructions on how to appeal the decision made. Notice to appeal the tax decision must be made in writing by the taxpayer (or their legal representative) to HMRC by completing the appeal form attached to HMRC’s penalty letter or by following the instructions on the letter.

It is essential to appeal promptly within 30 days and seek early specialist advice because a late response can be fatal to any appeal. Members of our legal team have first-hand experience and working knowledge of the internal workings of HMRC. As specialist London Tax Disputes Solicitors, we have the competency and experience to unblock negotiations with HMRC.

Stage 2(i): HMRC Internal Review

The HMRC internal review process can be used by a taxpayer when appealing a HMRC decision. If the stage 1 appeal to HMRC after the penalty notice is issued is unsuccessful then either the taxpayer or HMRC can request an internal review of the decision.

The review is a statutory process conducted by a different tax officer from the first reviewer and is seen as a useful tool in providing a fresh set of eyes on the interpretation of facts. Not on whether the decision was “fair” or for a technical dispute- but on determining whether the decision was made in line with HMRC guidelines.

There are a number of advantages in utilising the internal review procedure. The internal review process is conducted within strict time periods, allowing the taxpayer to gain control of the timing of the case and resolution may be achieved faster than using the Tax Tribunal option. Moreover, previously published official statistics shows that 49% of internal reviews have resulted in HMRC penalties being annulled or amended. This demonstrates that HMRC is prone to making errors when issuing a penalty notice.

HMRC’s internal review process is subject to a number of formalities and strict time limits, it is important to seek legal representation as soon as possible. If the taxpayer neither accepts the review process nor notifies the appeal to the Tax Tribunal, the tax dispute is considered settled under section 54 TMA 1970 in line with HMRC’s view of the matter. Therefore, it is important to seek legal representation early to help navigate the internal review process because after missing this response deadline, it is impossible to resile from the settlement according to section 54(2) TMA 1970 (unless the Tax Tribunal allows late notification of the appeal).

If after the completion of internal review process the tax issue is still in dispute then recourse is also available by appealing to the First Tier Tax Tribunal (section 49D, TMA 1970) or by considering alternative dispute resolution (ADR).

Stage 2(ii): Appeals to the Tax Tribunal

The Tax Tribunals can be used by a taxpayer when appealing a HMRC decision. If the appeal to HMRC after the penalty notice is issued is unsuccessful and the HMRC  internal review procedure has not yielded a satisfactory conclusions then recourse is available by appealing to the First Tier Tax Tribunal (section 49D, TMA 1970). It is not permissible to appeal to the Tax Tribunal during the course of the internal review.

The procedural rules governing the First Tier Tribunal are found in the Tribunal Procedure (First-tier Tribunal) (Tax Chamber) Rules 2009 (SI 2009/273). The Tax Tribunal is completely independent of HMRC and is governed by an overriding objective to deal with cases fairly and justly (rule 2, First Tier Tribunal Rules (FTR 2009)). The Tribunal will consider the evidence of both parties, equally whilst the judge heavily relies on previous case law.

Commencing proceedings at the First Tier Tax Tribunal is subject to statutory time limits. It is recommended that legal advice is sought as soon as you become involved in a HMRC dispute to prevent a situation where a potential claim becomes time-barred.

The First Tier Tax Tribunal will then give a direction allocating the case to one of four categories, which all have different procedures:

  1. Default Paper cases:  ordinarily involve uncomplicated issues where the facts are simple and there is little dispute as to the law. The First Tier Tax Tribunal will determine the issue without a hearing (unless either party has requested one).
  2. Basic cases: typically include standard tax penalties and covers both direct and indirect taxes and includes VAT “migration appeals” as well as all “reasonable excuse” appeals. These cases are generally disposed of at a hearing and involve a minimal exchange of documents prior to the hearing.
  3. Standard cases: the cases that can be diposed of in one day, in an area of uncomplicated law, with one witness providing uncontested evidence, are assigned to the Standard track.
  4. Complex cases: cases are assigned here if it satisfies one of the conditions in rule 23(4), FTR 2009. The procedural Tax Tribunal rules are the same save for a special costs regime applying for Complex cases.

The First Tier Tax Tribunal is in essence a fact-finding court, therefore it is imperative to prepare the optimum set of facts in advance and this usually requires the most extensive preparation. We are well-versed in the Hearing procedure itself and presenting our clients’ cases to the Tax Tribunal. We consider the preparatory stage an essential part of the Hearing process and extensively complete the best factual picture from which the First Tier Tax Tribunal will draw its inferences.
