Apologies, I misunderstood the point you were making. I thought you were looking to carry forward the tax relief.Since I'm only starting with AVCs my idea was to put a lump sum in to the same pot I use for AVCs. I wouldn't try to carry forward tax relief on that lump sum to future years since I will be maxing out AVCs every year until I retire anyway.
Likely only on 75% of it if you factor in the tax free lump sum?To get your hands on that, you'll have to pay tax
