That's true. I think it's a less likely scenario than exceeding the Pension Lifetime Allowance, which used to be £1.5m but was cut in stages, finally £1m in 2016/17. Whilst it was subject to inflationary increases thereafter, it hasn't been increased this latest tax year.
£1m might sound like an enormous pension but it's only enough for an income of around £28k if you take an inflation-linked annuity. Yet if you exceed it, any excess you take as a lump sum is subject to a whopping 55% tax rate (excess taken as income is subject to a 25% rate, which isn't quite as bad, but still!).
Neither of these situations are ones that many people face, however with the amount that the government has spent over the last 15 months, it's entirely foreseeable that there will be some significant tax increases across the population.
