Gibraltar Corporate Partners: it’s Offshore Advisory Group, rebranded
Back in June we reported on perhaps the strangest firm we’ve come across – “Offshore Advisory Group”. Offshore Advisory Group recently rebranded as Gibraltar Corporate Partners. Offshore Advisory Group promoted itself by pushing extreme political commentary, including conspiracy theories originating in Russian propaganda outlets. It used the attention this attracted to sell a tax avoidance […]

The mansion tax map: where the money comes from
We’ve modelled the impact of the English “mansion tax” by analysing land registry data on every property transaction since 1995. This lets us estimate how much each postcode and Parliamentary constituency will pay. It’s an approximate and lower-bound estimate – see methodology details below. As property taxes are devolved, there’s currently no mansion tax in […]

The Budget – what it says
Here’s our summary of the Budget and a quick take on what the various measures are likely to mean. (The first draft of this article appeared unusually early, thanks to the OBR accidentally publishing their assessment of the Budget about half an hour before the Chancellor started her speech.)

The Budget small print: six key reforms to watch
Most of the attention during and after the Budget will be on the big tax-raising measures.

If we take inflation out of the numbers, and express everything in today’s money, has council tax actually gone up? Did council tax bills go up? Here’s the average Band D council tax for England, Wales and […]

Criminalising tax avoidance – I’ve changed my mind
We’ve investigated many tax avoidance schemes. None of them had any technical merit – indeed many were closer to tax evasion than tax avoidance. All of the schemes, without exception, should have been disclosed to HMRC under DOTAS – the rules requiring up-front disclosure of tax avoidance schemes. None of them were. The whole point […]

Could we have stopped Revolut’s founder from leaving the UK?
Nik Storonsky, the billionaire founder of Revolut, has reportedly left the UK and become tax resident in Dubai – a move that could save him more than £3 billion in UK capital gains tax. His departure raises a larger question for the UK tax system: could we have stopped him leaving? Either with the carrot […]

PPE Medpro made £200m but never filed full accounts. The law should change.
PPE Medpro is the company which provided £200m of PPE to the Government in dubious circumstances, of which £122m was faulty. Reports suggest it made £65m profit – but we can’t know for sure. Its finances are a mystery, because it was allowed to file only abridged accounts. Why? Because under UK law, PPE Medpro […]

Why Angela Rayner is likely to pay £8,000 in stamp duty penalties
We now have enough information to be able to answer the question of whether Angela Rayner will be subject to HMRC penalties, and how large those penalties will be. For the reasons below, in my view Ms Rayner will very likely receive penalties for a “careless” error of around 20%. The background On the basis […]
