“As we have already stated, there was and is no appeal against an amount of tax shown as owing on a self-assessment. The law in that respect is not surprising: tax is self-assessed so a taxpayer cannot expect to have a right to challenge his own actions.” “We note that while a taxpayer has no right to challenge his own self-assessments, he does have a right to amend them. The amendment must be made in accordance with the terms of s9ZA TMA which requires the amendment to be made within 12 months of the filing date.”
“I accept the submission of [HMRC] that Parliament has set down in the self-assessment system carefully defined time limits for enquiries, assessments and claims which balance the need to give finality and certainty to taxpayers and the Exchequer, with the need to provide sufficient flexibility to ensure fairness in the system. It has created a specific statutory procedure for the extension of certain of those time limits where it has considered it appropriate. The [Upper Tribunal’s] construction cuts across this balance without a clear warrant for doing so in the section.”
“It is obvious that, under a system of self-assessment, tax will from time to time be paid in error and that that tax will have to be repaid. That is an inherent risk of a system of self-assessment. Statistically a certain percentage of tax receipts will have to be repaid, and we consider that government should not be able to discharge its obligations in restitution to the taxpayer by choosing to take a course which would dilute its repayment obligations.”
“(2) The Tribunal must strike out the whole or a part of the proceedings if the Tribunal — (a) does not have jurisdiction in relation to the proceedings or that part of them;”
“(1) The overriding objective of these [Tribunal Rules] is to enable the Tribunal to deal with cases fairly and justly. (2) Dealing with a case fairly and justly includes— (a) dealing with the case in ways which are proportionate to the importance of the case, the complexity of the issues, the anticipated costs and the resources of the parties; (b) avoiding unnecessary formality and seeking flexibility in the proceedings; (c) ensuring, so far as practicable, that the parties are able to participate fully in the proceedings; (d) using any special expertise of the Tribunal effectively; and (e) avoiding delay, so far as compatible with proper consideration of the issues.”
