Hello, I am Keith, one of the experts on Just Answer, and happy to help you with your question.
You are correct in your surmise. Pension contributions by you and your employer aggregated may not exceed 100% of emoluments so that leaves 19K of contributions availabkle should your employer so proceed. As you are aware of the limits and the carry over rules, I will not comment thereon. These can be quite valuable, however in reducing tax exposure.
Redundancy and severance pay do attract other reliefs as the first 30K is exempt from tax altogether. In this case it does not really alter the price of cheese, as my old boss was wont to say, however it is something to bear in mind and tuck away for future reference.
I do hope that my response has been of assistance to you.
