I'm pretty clued up on the old scheme, where you sacrifice either £243 or £100 max per month.
But struggling with the new scheme, where the gvt add 20p to your 80p in a special NSI account.
Can one parent remain in the old scheme and the other do the new scheme? I can't find any definitive answer online (just that both parents can switch over but can't participate in both). But what about parents who are not separated, doing one scheme of each? Has anyone come across this?
