Government guidance shows the cost as a relief has increased markedly from £2.8 billion in forgone National Insurance contributions in tax year 2016/2017, rising to £5.8 billion in 2023/2024.
The Government's changes are expected to bring in £4.8bn in 2029/30. If it ever happens- at present it's just there as something to help meet the fiscal rule.
So we won't be that far from 2016/7 really. When, according to Stephen Bush, hardly anyone must have tried hard to save for a pension.
I have a friend who works in pensions and he's I'd guess a natural finance conservative, and he said that he didn't think you could justify some of the tax treatments for pensions at the top end, and could understand if there restrictions from the Labour Government. The one thing he didn't like was politicians who ignore trade offs with changes. I'll ask him where he stands on this.
