Background
In 2016, the appellant, Richard Warner, purchased two adjacent plots of land and filed the required Stamp Duty Land Tax (SDLT) returns, self-assessing a liability of £168,500. However, he failed to claim Multiple Dwellings Relief (MDR), which would have substantially reduced the tax due to £41,300. The assessed SDLT was never paid.
In July 2018, well after the 12-month statutory deadline for amending a tax return had passed, Mr. Warner wrote to HM Revenue and Customs (HMRC) requesting to amend his returns to claim the forgotten MDR. HMRC rejected the request on the grounds that it was out of time. After further correspondence failed to resolve the issue, Mr. Warner appealed to the First-tier Tribunal (FTT).
The FTT struck out the appeal, finding it had no jurisdiction. It held that HMRC’s rejection of a late amendment was not an appealable decision. The FTT also dismissed Mr. Warner’s argument that his letter should have been treated as a claim for “overpayment relief,” a separate procedure with a more generous four-year time limit. Mr. Warner appealed the FTT’s decision to the Upper Tribunal.
The Court’s Holding
The Upper Tribunal dismissed the appeal, upholding the FTT’s finding that it lacked jurisdiction. The core issue on appeal was whether Mr. Warner’s 2018 letter, which was explicitly a request to amend his original tax returns, could and should be treated as a valid claim for “overpayment relief” under a different statutory scheme (paragraph 34 of Schedule 10, Finance Act 2003).
The Tribunal held that it could not. It reasoned that a document that is neither intended by its sender nor understood by its recipient as a specific type of claim cannot be retroactively re-characterized as such. Mr. Warner’s letter and all subsequent correspondence consistently focused on amending the original returns to claim MDR. At no point until years later in the litigation did he frame it as a claim for overpayment relief. The Tribunal concluded that “a claim for MDR is not a claim for overpayment relief.”
Because the letter did not constitute a valid claim for overpayment relief, HMRC had not made any decision regarding such a claim that would give rise to a right of appeal. Therefore, the FTT was correct to rule that it had no jurisdiction to hear the matter. The taxpayer had chosen one procedural path (amending a return) and, having failed because it was out of time, could not salvage the claim by arguing it was something else entirely.
Key Takeaways
- A request to amend a tax return to claim a specific relief is procedurally distinct from a claim for “overpayment relief” under paragraph 34 of Schedule 10, Finance Act 2003.
- Taxpayers cannot retroactively re-characterize a failed, time-barred request under one statutory regime as a valid claim under another, even if the underlying entitlement to the tax relief is not in dispute.
- The form and substance of a taxpayer’s claim matter; a court will analyze how the claim was framed by the sender and understood by HMRC at the time it was made.
Why It Matters
This decision reinforces the critical importance of adhering to strict procedural requirements and deadlines in UK tax law. It serves as a caution to taxpayers and their advisors that selecting the incorrect procedural route to claim a relief can be fatal, preventing any judicial review on the merits of the entitlement. The ruling underscores that the self-assessment system places the onus on the taxpayer to make the correct type of claim within the correct time frame, and courts are unwilling to “rescue” a procedurally flawed claim by treating it as something it was never intended to be.
