Topslicer Tool

From just £299 + VAT

Absolute’s Taxpert Topslicer Tool is the only tax product that you can use to check the calculation of tax on chargeable event gains (CEGs). The Topslicer Tool could help your clients save thousands of pounds in tax from future CEG liabilities and, more important, could help them reclaim overpaid CEG taxes from the past.


FA 2020 introduced new legislation to clarify TSR by specifying how allowances and reliefs can be set against insurance policy gains when calculating top slicing relief. This change in legislation was prompted by HMRC’s defeat in the First-tier Tribunal Silver case. See below for further details.


But HMRC are still not applying either the methodology approved in Silver or the rules introduced by the Finance Act 2020 correctly.  The recently decided case Judges confirmed that HMRC were still wrongly calculating TSR despite the Silver decision and that HMRC are wrongly applying the FA 2020 provision to events occurring before 11 March 2020. See Tim Good's latest analysis here.


We believe that our Topslicer Tool is the only top slicer calculator in the UK which accurately works out CEG liabilities and TSR in accordance with the method laid down by the First-tier Tribunal in the Silver and Judges cases.

Changes to Top Slicing Relief legislation


Until recently HMRC used a simplified and outdated method to calculate top slicing relief. In many cases they have under calculated TSR by tens of thousands of pounds.


Tim Good first explained how HMRC’s top slicing relief (TSR) calculator was incorrect in his ‘Calculating top slicing relief’ article which was published in Taxation magazine in September 2017. Since that time, the issue was taken further by Marina Silver who has successfully argued her case at a HMRC First-tier Tribunal. The judgment from that Tribunal can be read here. In March 2020 HMRC withdrew their appeal against the Silver judgment.

Update on the Silver case

Judge Richards of the Upper Tribunal consented in March 2020 to HMRC’s withdrawal of the appeal against the decision of the First-tier Tribunal in the Marina Silver case. The Judge has also confirmed that HMRC will pay Mrs Silver’s reasonable costs. The Judge was asked that HMRC’s appeal be dismissed rather than withdrawn (we remain concerned that HMRC would be able to resist other claims on the grounds that the FTT judgment is not binding on them). The Judge resisted this request and so there may be a battle yet to be fought, but in the meantime HMRC now have no grounds on which to reject claims brought on the basis of the analysis that Tim Good first set out in Taxation Magazine in September 2017.


The outcome of the Silver case has prompted the Government to clarify how allowances and reliefs can be set against life insurance policies in the Finance Act 2020.


Tim Good has written a follow up article in Taxation Magazine (April 2020) about the TSR changes announced in the 2020 Budget and why it matters.


The Silver case has highlighted the importance for accountants and relevant professional services firms of double checking their tax calculations for any client (including deceased estates) that have a CEG, to see if they have a possible claim. CEGs arise on investment bonds or single premium non-qualifying life policies, which have been widely sold by the investment industry over recent decades.

The Judges case

The Judges case was heard on 19 January 2022 and the decision was published on 18 February 2022. The case involved a difference in the calculation of TSR in the year of death (2017-18) of over £44,000.


These two cases could have major implications for your clients, who could now reclaim hundreds if not thousands of pounds in overpaid or over-calculated tax. In the Silver case the taxpayer recovered over £19,000 and in the Judges case over £44,000.

March 2022 Update from Tim Good


I continue to see multiple copies of correspondence from HMRC officers dealing with outstanding top slicing relief issues.

As you will see from reading the March 2022 update there is still a lot to play for!


There are three main areas of interest and in each of these I would say that HMRC are on the back foot:


  • Process issues – where typically HMRC are out of time to correct or open enquiries;


  • Application of the Silver and Judges judgments to cases before 2018-19;


  • Overpayment relief claims.


Product overview


The Taxpert Topslicer Tool gives a quick, easy and accurate way of checking the HMRC calculation of TSR on CEGs.

The Topslicer Tool performs the calculations set out in s535 ITTOIA 2005 to calculate the correct amount of TSR and then compares the result to the HMRC calculation. The Taxpert Topslicer Tool shows full workings which can be used to support a submission to HMRC.

This means you can:

  1. make historical checks on your client’s tax liabilities to see if there is a difference between what they paid and what they should have paid. The software highlights, where appropriate, how much they may have overpaid; and


  1. use the Topslicer Tool as a tax planning aid to reduce future CEG tax liabilities.

In a nutshell, the Topslicer Tool is the only calculator currently on the market which follows the methodology approved by the Tribunal in the Silver case. It allows you to:


  • work out the top slicing relief on chargeable event gains;
  • input income and reliefs figures for the relevant tax year and instantly see the tax result;
  • select any tax year from 2013-14 to 2020-21;
  • show the HMRC figures and highlight any differences.


The Topslicer Tool also includes the full workings that can be submitted to HMRC as part of a claim.


Taxpert Topslicer Tool in action

  • Marina cashed in an investment bond triggering a chargeable event gain in 2019-20 of £120,000 after 15 years. She had pension and savings income of £40,000. HMRC said her tax bill for 2019-20 was £40,000. The Taxpert Topslicer tool makes it just £8,500.


  • Neville cashed in an investment bond triggering a chargeable event gain in 2017-18 of £10,000 after 6 years. He had pension and savings income of £45,000. HMRC said his tax bill for 2017-18 was £7,500. The Taxpert Topslicer tool makes it just £6,700.

Its application could help some of your clients save thousands of pounds in tax and help you to advise on the optimum encashment strategy for 2021-22.
