Hello,
This week, we are pleased to publish a new suite of subscriber guides focusing on globally mobile employees. We also have the latest statistics on Inheritance Tax, estimates of the number of taxpayers that will be impacted by Making Tax Digital for Income Tax, as well as more decisions from the tax tribunals.

In an increasingly international business world, accountants and tax advisers regularly encounter clients with globally mobile employees.
This is a complicated area of UK tax and our new set of guides in Editor’s Choice will help navigate the rules which apply in different circumstances. Our ‘Globally mobile employees: PAYE reporting obligations toolkit’ is the recommended place to start when examining the position of employees sent to work overseas or employees coming to work in the UK.
In other news, HMRC’s latest statistics reveal that Inheritance Tax (IHT) receipts reached record levels in 2022-23 despite significantly increased claim values for both Agricultural Property Relief (APR) and Business Property Relief (BPR). With the Nil Rate Band and Residence Nil Rate Band both frozen until 5 April 2030, this trend seems likely to continue, underlining the importance of planning, where possible.
Turning to the tax tribunals, it is well known that reliance on an adviser cannot often constitute a reasonable excuse for a taxpayer’s failure. As with many general rules, there are exceptions, and this is seen in the First Tier Tribunal’s (FTT) decision in Parwinder Gill v HMRC, featured below. This case is well worth reviewing to examine the circumstances which led the FTT to its conclusion.
More news, cases and updates below.

Tax Cases

Taxpayer's reliance on adviser valid reason for delay
In Parwinder Gill v HMRC [2025] TC09602, the First Tier Tribunal (FTT) allowed an application to reinstate an appeal previously struck out due to the taxpayer's failure to comply with directions. The taxpayer had a reasonable excuse, as his adviser did not inform him of his responsibilities.
HMRC able to force VAT deregistration
In Elphysic Limited & Ors v HMRC [2025] UKUT0236, the Upper Tribunal (UT) found that HMRC had the power to deregister a company for VAT, where the VAT registration number was used for fraudulent purposes.
EIS appeal denied on trading requirements failure
In York SD Limited and Ors v HMRC [2025] TC09589, the First Tier Tribunal (FTT) denied the taxpayers’ Enterprise Investment Scheme (EIS) relief claim, ruling that preliminary work without a profit motive was not genuine trading. Main projects which were still incomplete at the two-year deadline could not be treated as qualifying business activities.
