Tax 2021 (2020 income)

Hello all, and @rogerspencer - the topic of pension lump sums was my very first query on Survive France -

I found out a bit more from a PM with another poster who did take the 25% before becoming France taxable - and then the rest at the 7.5% rate in France. However, strictly, if taking a lump sum at 7.5% it should be all taken in one go - in fact the extra tax on the 25% which would have been tax free is approx 2K per 100K of pension so is it really worth taking the risk?

Of course if one is doing drawdown then one wouldn’t take all the funds in one go - but then why wouldn’t one take advantage of the 7.5% tax rate? And sorry if this is a bit of a hijack of the 2020 tax return - but I saw the posts here. Maybe better to add to my original post?
