What Should I Do Before Leaving Taiwan?

I will be moving back home next month. Is there any particular things I shoud do beforing leaving. I have an APRC, do I need to go to the immigration office and inform them that I am leaving? Do I need to inform the household registry?

also what about collecting your taxes?

Latest amendments discussed said that APRC holders could leave up to 5 years without losing their status. You could stop by NIA and inform them that you will be leaving for an indefinite amount of time -no need to say forever- and take it from there, so you will not lose that status, in case you may want to come back for a spell or something, YNW.

Definetively taxes, could be a nice sum, and leaving is also expensive, so anything helps.

Nothing else comes to mind, aside from taking lots of pictures, copies of work documents, and arranging a party or two.
