This year, my employer's super contributions have exceeded the concessional contributions cap by approx $5k (i.e. my total contributions total $35k).
When I logged into my ATO account, I found that I am eligible to carry forward unused contribution cap amounts.
Do I need to 'opt-in' to activate the above, or will this be automatically taken into account?
If I do nothing, am I likely to get hit with an increased tax bill?
Cheers.
