Just shows how little people understand pensions.
It doesn't mean anything to those already with an annuity, state pension, final salary pension or some occupational pensions. This change only affects people who have a crystallised pension in drawdown (typically early retirees at 55-65), or uncrystallised pensions for those over 75. Spouses and dependent children already could inherit these tax free as pensions. Others were charged 55% tax - and it's only these others that may benefit. If you don't know what a crystallised/uncrystallised drawdown pension is, then chances are it doesnt affect you.
So what happens after these changes? Say a rich elderly relative dies and leaves you a pension pot of £200K. This is paid to you and taxed at your marginal rate. If you earn the national average wage of £25K, then that makes your income for the year £225K, so you're taxed at 0% on the first £10K, 20% on the next £30K, 40% on the next £110K, and 45% on the remaining £75K. So a tax take of around £84K. And you'll probably lose any child benefit for that year too.
Probably the best thing you could do is stick the money into your own pension pot, altough you will be limited to £25 p/a due to your wage.
The change probaby is good news for some, but I don't think it deserves headline news treatment because it'll affect hardly anyone.
