I wrote this week about talks between the Tories and Lib Dems about the possibility of lowering the cap for how much workers can put into their pension pots while still enjoying tax relief.
Since then a couple of pensions experts have got in touch to explain some further implications of the measure, which mean that for two reasons, it could be more controversial than I first realised.
Firstly, I suggested that people enjoying the maximum 50% tax break enjoy a 50p top-up to their pension pot for every £1 they put in.
In fact, the relief is worth even more, because the amount is a tax relief calculated on pre-tax income. So if you qualify for the 50% relief, and put in £1, your tax is waived, meaning that the government has essentially put in 50p of the £1 you put it. Cancelling this for some people would therefore be even more of a blow than I first calculated.
