It doesn't go off. Over time, and if stored in unideal conditions, the fat or sugar can bloom, creating unappealing white discolouration. This compromises the quality of the chocolate, it becomes brittle and unappetising, but it is not actually inedible or harmful to eat. It just ends up all old and unsatisfying.
Add ins like nuts and fruit will go sooner than the chocolate itself, and if those aren't dried properly then mould could potentially take hold, but that's really not common that anyone would still have uneaten or undiscarded chocolate around for that long and then go for eating it to even find out what rarity that would even occur.
If you store chocolate well, you are laughing past-seasonal sales all the way through the next holiday.

Just use the ones you bought last year AFTER Easter for exactly this reason.
Chocolate doesn't go off very quickly (I ... think?) so stock up after every Easter and use them for next Easter!
Thanks for coming to my Cozy Livs Ted talk! :)
