Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
25% of your lump sum is tax free leaving 63K exposed to tax at your marginal rate. It will be added to your earnings in the year of payment and taxed accordingly ie most of it at 40%.
It would thus make sense to defer receipt of the lump sum to a tax year when your earnings are reduced.
I do hope that you have found my reply of assistance.
Thank you for your support.
