What Actually Happened
Jeremy Francis Herrmann had entered into several tax avoidance schemes that HMRC later found didn't work. That meant a large amount of additional tax became due, including £9,960,157 following a closure notice issued in 2017, plus a further £4,012 from later adjustments.
In November 2023, Mr Herrmann's adviser asked HMRC to reallocate payments he'd already made to different tax years, a common request when someone wants to reduce the interest building up on an outstanding balance. Two further payments, of £2,363,062 and £1,348,760.66, were made shortly after to clear the outstanding tax and interest.
Everyone agreed that the tax had, in fact, been paid on time. The dispute was about what happened next: after the reallocation, HMRC's records showed some of those years as unpaid at the relevant deadline, and on that basis it issued £611,673.92 in late payment surcharges, along with separate late payment penalties for later tax years.
HMRC argued the legislation should be read purposively, meaning that if you ask for a reallocation, you should also accept the consequences, including penalties. Mr Herrmann argued that the law only cares whether tax was unpaid at a specific point in time, not what happens to the payment record afterwards.
