If you work less than 180 days in-country, do you get your tax back from the Indonesian Gov?
I worked for a reputable company in the Solomon Islands. The company deducted SI tax from my salary even though I was paid by the UK HQ.
I was there for two weeks. Tax refund? Forget it.
You give your origin as South Africa and you are going to work in Indonesia.
You ain't seen nothing. Just busk it as you go along.
