Martland and Medpro: when will the Tax Tribunals permit a late appeal?

To The Point
(6 min read)

When deciding whether to admit a late appeal, the Tax Tribunals must strike a balance between procedural integrity and the merits of the appeal.  In so doing, the Tribunal will consider the length of the delay and the reasons for that delay in all the circumstances.  Recent case law suggests that the Tribunal may give less weight to the importance of time limits than previously thought, though the position is far from settled.

It is important that taxpayers comply with the procedures set out in legislation and that the procedure rules are followed closely wherever possible. However, if you have missed a deadline, all is not lost as there are, generally, opportunities to apply late. In some cases HMRC can allow a late appeal, but the Tribunal may also grant permission to appeal if it considers it necessary to deal with the case fairly and justly, a test which has been the subject of some judicial dispute. The Tribunal has historically considered these applications by reference to the test set out in Martland v HMRC [2018] UKUT 178 (TCC) (Martland) but a number of recent Tribunal decisions suggest that the factors to be considered may be more evenly balanced than previously understood.
