“… a taxpayer’s self-assessment is a different matter. Plainly, errors of many different kinds may be made in such an assessment, and they may include errors about the availability of a relief. If the Revenue is dissatisfied with the taxpayer’s self-assessment, its remedy is either to amend the return or to open an enquiry into it under section 9A of TMA 1970. …, such an enquiry may extend to anything contained (or required to be contained) in the return. The boxes on page TC2 for ‘adjustments to tax due’ must in my view be regarded as containing information required to be contained in the return, where the taxpayer elects to perform his own self-assessment, because such adjustments form an integral part of the calculation of the tax due to be paid by him for the year in accordance with sections 23 and 24 of ITA 2007. It follows that the information contained in those boxes cannot be regarded as extraneous to the return. As I understand it, this is the essential point which Lord Hodge was making in Cotter at para 27, and if I may respectfully say so, I agree with it.” (para 57) The Revenue’s difficulty in the present case arose simply from their failure to take “the obvious step” of opening an enquiry into the 2010 return within the statutory time limit. Statute law and case law on discovery 108. Section 29 TMA 1970 (at the applicable time and in so far as relevant) provided for discovery assessments in the following terms: 29 Assessment where loss of tax discovered (1) If an officer of the Board or the Board discover, as regards any person (the taxpayer) and a [year of assessment]— (a) that any [income which ought to have been assessed to income tax, or chargeable gains which ought to have been assessed to capital gains tax,] have not been assessed, or (b) that an assessment to tax is or has become insufficient, or (c) that any relief which has been given is or has become excessive, the officer or, as the case may be, the Board may, subject to subsections (2) and (3) below, make an assessment in the amount, or the further amount, which ought in his or their opinion to be charged in order to make good to the Crown the loss of tax. ……….. (3) Where the taxpayer has made and delivered a return under [section 8 or 8A]2 of this Act in respect of the relevant [year of assessment], he shall not be assessed under subsection (1) above— (a) in respect of the [year of assessment] mentioned in that subsection; and (b) … in the same capacity as that in which he made and delivered the return, unless one of the two conditions mentioned below is fulfilled. ……... (5) The second condition is that at the time when an officer of the Board— (a) ceased to be entitled to give notice of his intention to enquire into the taxpayer's return under [section 8 or 8A] of this Act in respect of the relevant [year of assessment]; or (b) informed the taxpayer that he had completed his enquiries into that return, the officer could not have been reasonably expected, on the basis of the information made available to him before that time, to be aware of the situation mentioned in subsection (1) above. (6) For the purposes of subsection (5) above, information is made available to an officer of the Board if— (a) it is contained in the taxpayer's return under [section 8 or 8A]2 of this Act in respect of the relevant [year of assessment] (the return), or in any accounts, statements or documents accompanying the return; (b) it is contained in any claim made as regards the relevant [year of assessment] by the taxpayer acting in the same capacity as that in which he made the return, or in any accounts, statements or documents accompanying any such claim; ……………….. 109. At [10]-[60] of Atherton v HMRC[2019] UKUT 41 (TCC) the Upper Tribunal summarised the principles on discovery assessments as follows: ‘ 10. Two important principles underpin the construction and application of the discovery assessment provisions. 11. First, as this Tribunal stated in Burgess v HMRC[2015] UKUT 578 (TCC) , at [59]: “It must be recognised… that the assessment system that Parliament has legislated for is designed to provide a balance between HMRC and the taxpayer. Part of that balance is the requirement, in relation to discovery assessments and assessments outside the normal time limits, that HMRC satisfy the FTT that the relevant conditions for those assessments to have been validly made have been met.” 12. In this case, the burden of proof is on HMRC to establish on the balance of probabilities that the discovery assessment was validly made. 13. Secondly, the discovery provisions now in force were intended to be more restrictive of HMRC’s powers than the provisions in force prior to the introduction of self-assessment in 1996-97. In the context of the pre-2008 rules, which referred to fraudulent or negligent conduct, Moses LJ stated in the Court of Appeal’s judgment in Tower MCashback LLP 1 v HMRC[2010] EWCA Civ 32 , at [24]: “… apart from a closure notice, and the power to correct obvious errors or omissions, the only other method by which the Revenue can impose additional tax liabilities or recover excessive reliefs is under the new s29. That confers a far more restricted power than that contained in the previous s29.”
‘84. In our respectful opinion, the case law on TMA s 29 has taken a wrong turning, introducing a new restriction which is not present in the statute. That turning was indicated in Corbally-Stourton and Charlton , confirmed in Pattullo and upheld in Tooth . We note that in Tooth both parties had accepted that staleness invalidated an assessment, so the correctness of the proposition was not argued. 85. We nevertheless recognise and fully acknowledge that we are bound by Pattullo and by Tooth to set aside our views and proceed on the basis that an assessment is invalid if it was made when the discovery was “stale”, as that term has been interpreted by the case law. As we confirmed to the parties at the hearing, we have taken that approach in coming to a decision on the First Issue.’ 113. While some have expressed scepticism as to whether staleness invalidates assessments, there are many decisions of the Upper Tribunal and Court of Appeal which are authority for the proposition. These are binding on us unless and until such time as the Supreme Court in Tooth may decide otherwise. Accordingly, the concept of ‘staleness’ in discovery assessments exists and needs to be applied. 114. The Tribunal will apply the principles set out in the authorities above in relation to the requirements for, a) HMRC to prove that a discovery has been made, b) what constitutes ‘a discovery’, and c) the requirement that a discovery must be fresh and not stale. 115. In addition to the principles set out above there are also subjective and objective thresholds which are required to be met to raise a discovery assessment. 116. A discovery under section 29(1) of the TMA 1970 requires an Officer to have reason to believe a loss of tax exists ( Aramayo per Mr Justice Avory at p 289). The loss of tax must newly appear to the Officer ( Cenlon Finance per Viscount Simonds at p 204). 117. No new fact or law is required for there to be a discovery. The loss of tax, newly appearing to the Officer, can be for any reason, including a mere change of view, change of subjective opinion and indeed the correction of an oversight ( Charlton per Norris J. [37]). 118. In this regard, the threshold for an Officer’s discovery is low. At one point the Officer may not be of the view that a tax loss exists and at another, they conclude a loss of tax exists, such that an assessment ought to be raised. This is the subjective ‘threshold’ which exists under section 29(1) ( Charlton [28]). 119. An officer of HMRC’s subjective discovery pursuant to section 29(1) of the TMA 1970 must be proven on the balance of probabilities and positively advanced on appeal ( Burgess & Brimheath v HMRC[2015] UKUT 578 (TCC) per Judge Berner at [49]). 120. Put in another way, an Officer making the discovery must believe that the information available to them points in the direction of there being an insufficiency of tax ( Anderson v HMRC[2018] UKUT 159 (TCC) at [28]). An Officer’s conclusion is subjective, as is the test under section 29(1) ( Sanderson per Lord Justice Patten sitting in the Court of Appeal [25]). 121. However, the conclusion must be a reasonable conclusion based upon the evidence available to him or her ( Charlton [24]). As such, the Officer’s belief must be one which a reasonable Officer could form - see Anderson at [28]-[30]: “[28] In Sanderson, Patten LJ described the power under s 29(1) in this way (at [25]): 'The exercise of the s 29(1) power is made by a real officer who is required to come to a conclusion about a possible insufficiency based on all the available information at the time when the discovery assessment is made.' We consider, with respect, that this test is in accordance with the earlier authorities. This passage describes the test somewhat briefly because, of course, that case concerned s 29(5) rather than s 29(1). Having reviewed the authorities, we consider that it is helpful to elaborate the test as to the required subjective element for a discovery assessment as follows: 'The officer must believe that the information available to him points in the direction of there being an insufficiency of tax.' That formulation, in our judgment, acknowledges both that the discovery must be something more than suspicion of an insufficiency of tax and that it need not go so far as a conclusion that an insufficiency of tax is more probable than not. The objective test [29] The authorities establish that there is also an objective test which must be satisfied before a discovery assessment can be made. In R v Bloomsbury Income Tax Comrs , the judges described the objective controls on the power to make a discovery assessment. Those controls were expressed by reference to the principles of public law. In Charlton at [37], the Upper Tribunal referred to the need for the officer to act 'honestly and reasonably'. [30] The officer's decision to make a discovery assessment is an administrative decision. We consider that the objective controls on the decision making of the officer should be expressed by reference to public law concepts. Accordingly, as regards the requirement for the action to be ' reasonable', this should be expressed as a requirement that the officer's belief is one which a reasonable officer could form. It is not for a tribunal hearing an appeal in relation to a discovery assessment to form its own belief on the information available to the officer and then to conclude, if it forms a different belief, that the officer's belief was not reasonable.” 122. Consequently, a second stage and element of objectivity is introduced into section 29(1). Additionally, there need only be a progression in the Officer’s knowledge rather than a ‘eureka moment’ that leads to the subjective conclusion and discovery ( Hicks per Judge Scott [51]-[54]). 123. The fact that the Officer could have reached the conclusion earlier on the basis of the evidence available, does not preclude a discovery at a later date ( Sanderson per Mr Justice Newey sitting in the Upper Tribunal [24]). HMRC’s submissions 124. Mr Hall, on behalf of HMRC, submitted as follows. Principles 125. Firstly, capital gains tax losses are computed in the same way as gains chargeable to capital gains tax:s.16(1) Taxation of Chargeable Gains Act 1992 (“TCGA92”), subject to a few specified exceptions. 126. Secondly, capital gains tax is charged on the total gains of the year less any allowable losses of the year, less earlier losses brought forward: section 2(2) TCGA92. 127. Any capital loss must be notified and quantified before it can be allowed: s. 16 TCGA92. 128. Sections 42 and 43 TMA 1970 apply by virtue of section 16(2A) TCGA92. 129. By way of s. 42(2) TMA 1970, any capital loss must be made on a return where one has been issued under section 8 TMA 1970. 130. If no section 8 return is issued, then s.42(11) TMA 1970 directs that Schedule 1A TMA 1970 applies. 131. Where a return is made under section 8 TMA 1970, an enquiry under s. 9A TMA 1970 may be opened. 132. Any enquiry under s. 9A TMA 1970 may extend to considering “anything contained in the return, or required to be contained in the return, including any claim or election included in the return ” by way of s. 9A(4) TMA 1970. 133. A section 9A TMA 1970 enquiry may also extend to considering any amendment made under section 9ZA TMA 1970. 134. A return under section 8 may be amended with the window allowed by s. 9ZA TMA 1970, however if there is already an open section 9A TMA 1970 enquiry into a return, section 9B TMA 1970 operates to allow the s. 9ZA amendment to be taken into account in the relevant open s. 9A enquiry. 135. Where the enquiry window given by s. 9A(2)(a) TMA 1970 has passed, HMRC are precluded from opening an enquiry. 136. An assessment under s. 29 TMA 1970 may be made, subject to conditions laid down by s. 29(1), and s. 29(3) where a return under s. 8 TMA 1970 has been issued. 137. For any assessment to be valid, the assessing officer must believe that the information available to him points in the direction of there being an insufficiency of tax, and that it is one which a reasonable officer could form: see Jerome Anderson v HMRC[2018] UKUT 159 (TCC) [28] - [30]. 138. Additionally, s. 29(3) TMA 1970 sets out that at least one of two alternative conditions should be met, including that in s. 29(5), which requires the officer to not have been reasonably expected on the basis of the information available to him before that time, to be aware of the insufficiency of tax. 139. In Langham v. Veltema , (76TC259) Auld LJ stated at [36]: “It seems to me that the key to the scheme is that the Inspector is to be shut out from making a discovery assessment under the section only when the taxpayer or his representatives, in making an honest and accurate return or in responding to a section 9A enquiry, have clearly alerted him to the insufficiency of the assessment in question.” 140. Sections 29(6) and (7) TMA 1970 explain what is meant by “information being available”, and what is assumed to be in front of the hypothetical HMRC officer. 141. Section 34 TMA 1970 allows an assessment to be made within a certain time period, without HMRC having the burden of proof to show that there was carelessness on the part of the taxpayer. 142. “Staleness” is a concept which HMRC submit is not within s. 29(1) TMA 1970, nevertheless HMRC accept that the Tribunal is currently bound by decisions of higher courts. Applying the principles - 2000-01, 2001-02 143. For 2000-01, the Appellant submitted his SATR (being in response to a s.8 TMA 1970 Notice) on10 January 2002 , and an enquiry was opened on12 December 2002 under s. 9A TMA 1970. 144. For 2001-02 the Appellant submitted his SATR on1 October 2002 , and a s. 9A TMA 1970 enquiry was opened on8 August 2003 . 145. By way of a letter of24 January 2003 , amendments were submitted which were to be made to the appropriate boxes of the 2000-01 and 2001-02 capital gains pages of the SATRs. These were within time for any amendments to be made under s. 9ZA TMA 1970. 146. These amendments were for additional costs to be included in the computations of the capital gains tax liability arising on transactions that had already been reported on the returns and created losses. 147. Mr Hall contended that the correct regime to enquire into these additional costs was by way of s. 9A TMA 1970, as they fed into the computation of the capital gains tax position for the year under s. 2(2) TCGA92. 148. These additional costs were not stand-alone gains, to which Schedule 1A TMA 1970 applied, the legislation is clear, as was the letter of24 January 2003 . 149. Mr Hall submitted that the correct procedure had been followed, culminating in the closure notices issued under s 28A TMA 1970 in respect of these two years. 150. Reliance on Cotter v. HMRC[2013] UKSC 69 and Derry v . HMRC[2019] UKSC 19 is misplaced as the applicable capital gains tax legislation is different to the income tax claims legislation interpreted in those cases. The facts are clearly distinguishable. 151. Mr Hall submitted is not precisely clear as to why the Appellant is arguing that Schedule 1A TMA should be followed: taken to an extreme, any amendment resulting in a loss of one year being used in another would depend on an element of hindsight validation 2004-05, 2006-07, 2011-12, and 2012-13 152. For each of these later years, the capital gains tax computation for each year involved determining the net figure of the chargeable gains of the year, and deducting the losses brought forward from earlier years. 153. Therefore, Mr Hall submitted that as these figures were part of the computation of the liability of the Appellant, and were part of the return, the correct procedure was to enquire by way of s. 9A TMA 1970, which was done. 154. This view is reinforced by the way in which the legislation allows the losses to be preserved by reference to the annual exempt amount for capital gains tax, under s. 3 TCGA92. 2009-10 Assessment 155. Mr Hall submitted that it was useful to consider each of the years 2009-10 and 2010-11 together to illustrate why HMRC contend that there is a discovery assessment for 2009-10, but not for 2010-11. 156. As noted in the background, the enquiry caseworker had the issue of the losses brought to his attention on1 March 2012 , well outside the 12-month enquiry window for 2009-10 which expired in December 2011 but within the enquiry window for 2010-2011. 157. This letter of1 March 2012 then impinged on the validity of the 2010-11 assessment, under s. 29(6)(d)(ii) TMA 1970, and so the condition in s. 29(5) TMA 1970 was not satisfied for that year: the hypothetical officer would have been alerted to the existence of the MvJ losses at that time. The hypothetical officer could have been reasonably expected, on the basis of the information made available to him before that time, to be aware of them. That was why HMRC’s Review concluded that the 2010-11 assessment was invalid and should be cancelled. 158. However, for the 2009-10 assessment, neither the SATR for that year, nor for the two preceding years, contained a reference regarding the nature of the capital losses brought forward, and so reliance on s. 29(5) TMA 1970 was satisfied: the hypothetical officer was not alerted to the MvJ losses by December 2011 - by the time he ceased to be permitted to open an enquiry. An officer could only reasonable have been aware of the losses from1 March 2012 . 159. The assessment was also made within the time allowed by s.34 TMA 1970. 160. As to staleness, Mr Hall submitted that it may be seen that the enquiries into the underlying events that created the losses to be brought forward were ongoing, and so this is not a “ most exceptional ” case where HMRC had done nothing as envisaged in Patullo : see Marano [72-3]: ‘72. Lord Glennie agreed with Mr Gordon. He said... “… But I consider that Mr Gordon was right to accept that it would only be in the most exceptional of cases that inaction on the part of HMRC would result in the discovery losing its required newness by the time that an assessment was made.” 73. However, Lord Glennie did not interfere with the FTT’s finding of fact that the discovery had been made sometime between July and November 2009, with the assessment having been made in January 2010, and thus was not stale.’ 161. In view of Tooth being heard by the Supreme Court in spring 2021, Mr Hall respectfully submitted that if the Tribunal found that there was “staleness” in respect of the 2009-10 assessment, then the decision in this case on that point could be held over for submissions on that point alone, once the decision in Tooth had been published. 162. Concerning any argument about legitimate expectation, which was not in issue in the appeal, it was accepted that this is not within the jurisdiction of the First-tier Tax Tribunal, following the Upper Tribunal decision in HMRC v. Abdul Noor. Further, in Hely-Hutchinson, the Court of Appeal addressed MvJ issues of legitimate expectation and abuse of power. It was held in those judicial review proceedings that HMRC could resile from their previously expressed guidance in 2003 and follow their revised guidance of 2009 without that constituting an abuse of power. Appellant’s submissions 163. Mr Sherry, on behalf of the Appellant, submitted as follows. The Law on the first issue 164. The relevant provisions are to be found in theTaxation of Chargeable Gains Act 1992 : a. s.1 which levies the charge of the tax ; b. s.2 which provides for the amount to be charged to the tax to be chargeable gains less allowable losses; c. s.16 which deals with the computation of losses and in particular subsection (2A) which provides that a loss is not an allowable loss unless notified and that sections 42 and 43Taxes Management Act 1970 apply to such a notice as if it were a claim for relief . Section 43 deals with time limits and is of no further assistance; The relevant provisions are also found in theTaxes Management Act 1970 : d. Section 42(2) requires a claim to be made on a return if it can be, where a notice to file a return has been given in respect of the year in question . Section 42 goes on to provide that: e. Schedule 1A is to apply to claims and elections made otherwise than in a return; and f. Schedule 1B is to apply to claims for relief involving two or more years of assessments; g. Returns are generally to include a self-assessment of tax underTaxes Management Act 1970 s.9 ; h. The Revenue can enquire into such returns under Taxes Management Act s.9A. 165. Mr Sherry submitted that the decisions in Cotter v. R&CC (“Cotter”) and Derry v R&CC (“Derry”) are concerned with the mechanics of making enquiries. Section 9A enquiries are confined to the taxpayer’s self-assessment - matters which “feed into” the self assessment of tax due - see Cotter at [22] –[26] and Derry at [50] - [52] . 166. Mr Sherry submitted that the first issue comes to this: do the notifications of losses in issue “feed into” the self assessments for years to5 April 2001 and5 April 2002 ? If not, then any enquiry under section 9A does not extend to other matters for example “stand alone” claims even where they are made on the return form. Enquiries in those cases must be made pursuant to Schedule 1A to the TMA 1970. The Law: Issue 2 167. Mr Sherry submitted that the assessment for the year to5th April 2010 was raised on the basis that the Officer making it had made a “discovery” and so was permitted to make an assessment under section 29 of the TMA 1970. Section 29 provides that where the officer “discovers” new facts which lead him to believe that the assessment is insufficient, he may make an assessment. Submissions Issue 1 168. Mr Sherry submitted that, as noted above, at the time of the notifications under consideration, on24 January 2003 : a. For the year ended5 April 2001 , there was an open enquiry into the return (opened in December 2002); and b. For the year ended5 April 2002 , there was no enquiry on foot but subsequently an enquiry was opened into the self-assessment in August 2003. 169. HMRC in a letter in March 2003 accepted the claim for losses in respect of the first year and stated that the claim in respect of the second would be processed. 170. Issue One: was such notification (treated as closed for the purposes of ss. 42 and 43 of theTaxes Management Act 1970 ) within the scope of the s.9A enquiry? 171. Mr Sherry submitted the answer must be “no”. This is because the notification or claim to have the losses treated as allowable losses does not feed into the computation of assessment of income and gains for the year in question. All it does is to determine whether the losses in question are “allowable”. If the losses are allowable then maybe some or all or none of them will fall to be included in the computation of the gains for the year in question. Those amounts feed in to the self-assessment and may properly be the subject of a s.9A enquiry - see the passages in Cotter at [22]-[28]. 172. However, a notification which is treated as a claim in respect of losses to be treated as allowable losses, it is submitted, is a stand-alone claim and may only be enquired into under Schedule 1A, not section 9A of the TMA 1970. 173. In any event, the losses claimed did not in fact feature in the computations for the years to5 April 2001 and5 April 2002 . So as a matter of fact, there was no “feeding in” to the self-assessment of capital gains tax payable for either year. Mr Sherry submitted that the decision in Cotter establishes that for a matter to be under enquiry it must in fact “feed into” self-assessments. The Appellant relied upon the decision in Derry to assist in understanding Cotter. 174. The “amendments” to the Return made by the notifications being treated as claims do not alter or affect in any way the tax payable in respect of the year to5 April 2001 nor in respect of the year to5 April 2002 . 175. Accordingly, the appeal in respect of the allowable loss claims for the years to5 April 2001 and5 April 2002 should be allowed. 176. So far as the subsequent years under appeal are concerned, it is common ground that the capital gains tax computation for each of those years involved determining the net figure of chargeable gains for each year and deducting the available allowable losses brought forward from earlier years and not previously utilised. If the Appellant succeeds in respect of the notifications of losses, to be treated as allowable losses for the years to5 April 2001 and5 April 2002 , then it follows that they will be allowable losses for each of the subsequent years. Therefore, if the taxpayer succeeds in relation to the validity of the notification and as to the absence of any enquiry into them, the result is the losses stand for all subsequent periods and the appeals succeed for all periods. Submissions: Issue 2 177. Further and alternatively, Mr Sherry submitted that if the Appellant’s arguments on the first issue failed, then the discovery assessment for the year 2009-2010 was nonetheless invalid because: a. it is for the Revenue to establish that they have made a valid assessment in the circumstances authorised by TMA 1970, s.29 ; b. so far as the taxpayer is concerned, on the basis of Tooth (see [60] - [61]), the Revenue must establish that the “discovery” of facts led to the assessment and that there was no delay between the information coming to their attention and the assessment being made so as to render the discovery “stale” by the time of the assessment. 178. Mr Sherry submitted that the background to this matter generally includes the ongoing discussions between the Revenue and the Appellant’s agents so that when the notification was made in January 2012 as to the nature of the losses claimed in the return for the year to5 April 2010 , HMRC were in that context on full and immediate notice as to the nature of the losses being claimed. 179. The HMRC officer would have been immediately alive to the absence of an assessment in relation to that year and also of an ongoing enquiry enabling them to adjust the self assessment for the year 2009-10. 180. Therefore, Mr Sherry submitted, it would have been obvious that the self-assessed tax was, in the Revenue’s view, under assessed. This goes to the question as to whether or not in the circumstances there was delay. Mr Sherry submits that there was unreasonable delay between January or March 2012 when the discovery was made and the assessment being issued in December 2013 so that the discovery became stale and lost its essential newness. 181. Accordingly, Mr Sherry submitted the appeals should be allowed in respect of tax years 2001 and 2002 and the conclusions in respect of the notification of the losses reversed. Therefore, the appeals against all the conclusion notices in respect of all subsequent years and against the assessment for the year to5th April 2010 should also be allowed. Discussion and Decision The First issue Conclusion 182. We are satisfied that the Appellant’s claims in 2003 for MvJ losses for each of the 2000-01 and 2001-02 tax years were amendments to the returns and validly enquired into by the Revenue under section 9A TMA 1970 such that the later closure notices (and disallowance of losses) were validly issued by HMRC under section 28A. The Appellant has not discharged his burden of proof to establish otherwise. 183. As a matter of fact, the Appellant’s accountant’s letter of24 January 2003 presented the claim for the losses as amendments to the returns as filed rather than standalone claims. As a matter of law, for the reasons set out below, these were not standalone claims that required to be enquired into under Schedule 1A of the TMA 1970. On the facts of this case, the law, as interpreted in Cotter v HMRC , did not require the Revenue to have enquired into the losses as standalone claims under paragraph 5 of Schedule 1A TMA 1970 (with the mechanism for disallowing losses being closure notices issued under paragraph 7). 184. Further, the letter of24 January 2003 did not conform to the requirements for a standalone claim under paragraph 2 of Schedule 1A to the TMA 1970 - for example paragraph 2(4) requires a standalone claim to contain a declaration of truth. 185. As the notifications of MvJ losses by the Appellant for the two tax years were validly enquired into and disallowed, then they were not allowable losses available to be carried forward for use in subsequent periods tax years 2004 onwards. Therefore, the section 28A closure notices and amendments to the returns charging additional tax for the later years, 2005 onwards, were valid. 186. We have arrived at these conclusions largely for the reasons that HMRC submitted. Reasons 187. Firstly, capital gains tax losses are computed in the same way as gains chargeable to capital gains tax:s.16(1) Taxation of Chargeable Gains Act 1992 (“TCGA92”), subject to a few specified exceptions. 188. Secondly, capital gains tax is charged on the total gains of the year less any allowable losses of the year, less earlier losses brought forward: see section 2(2) TCGA92. 189. Any capital loss must be notified and quantified before it can be allowed: see section 16 TCGA92. 190. Sections 42 and 43 TMA 1970 apply by virtue of section 16(2A) TCGA92. 191. By way of section 42(2) TMA 1970, any capital loss must be made on a return where one has been issued under section 8 TMA 1970. Section 42(5) extends this to include claims to capital losses to be made on amendments to returns, as in the current case. 192. These provisions apply to the Appellant’s returns for the years 2001 and 2002. For each year, he was issued with a return which gave him notice to file for the years 2000-2001 and 2001-2002 and he duly filed such returns. 193. Section 42(11) TMA 1970 provides that Schedule 1A TMA 1970 only applies where a claim is made outside a section 8 return being issued. It does not apply to the facts of this case because the letter of24 January 2003 was an amendment to two returns filed pursuant to section 8 TMA 1970. 194. Where, as in this case, a return was made under section 8 TMA 1970, an enquiry under section 9A TMA 1970 may be opened. The enquires were opened under section 9A in December 2002 in respect of 2000-01 and August 2003 in respect of 2001-2002. 195. Any enquiry under s. 9A TMA 1970 may extend to considering “anything contained in the return, or required to be contained in the return, including any claim or election included in the return ” by way of section 9A(4) TMA 1970. 196. A section 9A TMA 1970 enquiry may also extend to considering any amendment made under s. 9ZA TMA 1970. The amendments to both returns were included within the letter of24 January 2003 and the schedule thereto. 197. Even if the claims in that letter did not constitute amendments to the return and were standalone claims, they would have been required to be contained in the Appellant’s returns because section 42(2) and (5) TMA 1970 required the capital losses to have been included in a return or amendment where section 8 notices to file had been issued as they had to the Appellant in this case. 198. A return under section 8 may be amended with the window allowed by s. 9ZA TMA 1970, however if there is already an open s. 9A TMA 1970 enquiry into a return, section 9B TMA 1970 operates to allow the s. 9ZA amendment to be taken into account in the relevant open section 9A enquiry. 199. The Appellant filed his returns for the two years pursuant to a section 8 TMA 1970 notice ‘for the purpose of establishing the amounts in which a person is chargeable to income tax and capital gains tax for a year of assessment’
