I don't know the figures on this so maybe it's a drop in the ocean, but I really think that 40% tax relief on pension contributions is unfair on lower earners.
I'm on a higher rate tax paying salary. I prioritise pension saving over many things. So I pay all of my earning over the 40% threshold into my private pension. And get 40% relief on it.
I do agree with some tax relief because it encourages people to use pension saving. It will probably save money for the government in the long run for me as an individual, because they won't need to pay me housing benefit.
But... I have excess income, so I can take advantage of it. If I have excess income I can afford to save.
I think pension tax relief should be reduced.
Instead of me getting 40%, use that money to give more relief to lower earning people, or to put actual money into pensions for those without one.
I'd base that on their earnings - you choose to be a SAHP to a 10yo with a wealthy other parent - your problem.
You work full time NMW then a "pension credit."
There is talk of a flat rate 30% but I don't think it goes far enough.
