HMRC Rejected Review? What Happens Next

Receiving a letter from HMRC rejecting a statutory review can be deeply unsettling. Many taxpayers assume that a rejection means the end of the road, that HMRC’s decision is final, or that enforcement action will now follow automatically. In reality, a rejected review is often not the end of the dispute but the point at which strategic decisions become most important.

This guide explains what a rejection by HMRC actually means, what options remain available, and what steps should be taken next. It addresses the legal framework governing appeals, the role of the tribunals, and the practical considerations that often determine whether a dispute can still be resolved favorably.

Understanding What HMRC Has Rejected

Before deciding what to do next, it is critical to understand precisely what HMRC has rejected. In many cases, HMRC has not rejected an appeal entirely but has issued a conclusion following an internal statutory review. In other cases, HMRC may assert that a review is invalid, late, or outside jurisdiction.

A statutory review is an internal reconsideration carried out by a different HMRC officer. While reviews are intended to provide an independent check, they are still conducted within HMRC and do not bind the taxpayer. A review conclusion does not determine the dispute conclusively. It simply confirms HMRC’s position and triggers the next stage of the formal dispute process.

Where HMRC has rejected outrightly, the reasons given should be examined carefully. Rejections are often based on procedural grounds rather than the substantive merits of the tax position.

Does a Rejected Appeal Mean HMRC Is Right?

A rejected review does not mean HMRC’s position is legally correct. HMRC rejects a significant proportion of appeals that later succeed before the First-tier Tribunal. The tribunal is an independent judicial body and is not bound by HMRC’s view of the facts or the law.

In Hok Ltd v HMRC [2012] UKUT 363 (TCC), the Upper Tribunal emphasised that HMRC’s conclusions are not determinative and that disputes must be resolved by applying the correct legal tests to the evidence. This principle underpins the entire tribunal system.

It is therefore a mistake to assume that a rejection reflects the strength of HMRC’s case. Often it reflects HMRC’s litigation strategy or a narrow interpretation of the facts.

What Are the Next Formal Options?

Once HMRC has issued a review conclusion, the next step is usually an appeal to the First-tier Tribunal (Tax Chamber). Strict time limits apply. In most cases, the taxpayer has 30 days from the date of HMRC’s decision to lodge an appeal with the tribunal.

The tribunal appeal is the first point at which the dispute is considered independently of HMRC. The tribunal has full jurisdiction to consider the facts, apply the law, and determine whether HMRC’s decision was correct.

In Harrison v HMRC [2022] UKUT 216 (TCC), the Upper Tribunal reviewed how the First-tier Tribunal applied legal principles and stated guidance on when appellate intervention is appropriate, reinforcing the idea that a tribunal decision can be challenged for errors of law. This remains a cornerstone of tax litigation and provides protection against decisions based on assumption or misdirection.

What If the Appeal Deadline Has Been Missed?

Many taxpayers only seek legal advice after HMRC has rejected an appeal or review and the tribunal deadline has passed. Missing a deadline does not necessarily mean the dispute is lost.

The First-tier Tribunal has discretion to allow late appeals where it is fair and just to do so. The tribunal considers factors such as the length of the delay, the reasons for it, the merits of the underlying appeal, and any prejudice to HMRC.

In Martland v HMRC [2018] UKUT 178 (TCC), the Upper Tribunal confirmed that the tribunal must balance procedural discipline against the overriding objective of dealing with cases fairly and justly. Strong substantive merits can weigh heavily in favour of allowing a late appeal.

Can HMRC Enforce the Tax After Rejecting a Review?

HMRC may seek to enforce a tax assessment once it considers the dispute concluded. However, enforcement is not automatic in every case and may be inappropriate where an appeal to the tribunal is pending or where enforcement would cause disproportionate hardship.

In certain circumstances, it is possible to seek a postponement of tax pending appeal. This can be critical where immediate payment would cause severe financial difficulty or undermine the taxpayer’s ability to continue trading.

HMRC’s enforcement powers must still be exercised lawfully and proportionately. In R (on the application of HMRC) v FTT [2017] UKSC 23, the tribunal scrutinised HMRC’s approach to recovery action in the context of ongoing disputes, emphasising the tribunal’s jurisdiction and the limits of HMRC’s procedural powers.

Is Alternative Dispute Resolution Still Available?

Even after a review has been rejected, alternative dispute resolution may still be appropriate. HMRC’s ADR process allows disputes to be mediated by an independent facilitator and can be particularly effective where the disagreement concerns factual interpretation or evidential weight rather than pure points of law.

ADR does not suspend tribunal deadlines, so it must be approached strategically. In many cases, ADR is pursued alongside protective tribunal appeals to preserve procedural rights.

What Happens at the First-tier Tribunal?

Tribunal proceedings are less formal than court litigation but remain legally rigorous. Evidence is tested, witnesses may be cross-examined, and legal submissions are made on statutory interpretation and case law.

The tribunal’s role is to decide the dispute afresh. It is not limited to reviewing HMRC’s reasoning. Many taxpayers misunderstand this critical distinction.

In HMRC v Pendragon plc [2015] UKSC 37, the Supreme Court reaffirmed that tax disputes must be resolved by applying the law correctly, even where HMRC’s approach has been long-standing or administratively convenient.

What If the Tribunal Decision Is Unfavourable?

If the First-tier Tribunal dismisses the appeal, further options may still exist. Appeals to the Upper Tribunal may be available where the First-tier Tribunal has made an error of law. Errors of law include misinterpretation of legislation, failure to apply binding authority, or procedural unfairness.

Common Mistakes After An Unfavourable decision

One of the most common mistakes is doing nothing. Silence is often interpreted by HMRC as acceptance of its position and may lead to enforcement escalation.

Another frequent error is corresponding extensively with HMRC without protecting tribunal deadlines. Informal engagement does not stop the clock.

Finally, many taxpayers underestimate the technical complexity of tribunal litigation. Appeals succeed or fail on legal framing and evidential preparation, not on assertions of unfairness alone.
