I will be in the same boat as you on Friday!
I have checked with my HR department and they said that that is basically all you need. If you have had an NPWP Number, it may be helpful to have some sort of proof of that, just in case they try to charge you the fiscal when you leave.
If you had NPWP, you do not have to pay the fiscal when you leave.
If you did not have NPWP, then you may have to pay the fiscal.
