20% tax new rule?

I have been teaching here for 5 years and recently quit a job. I have been offered a new job at TLI and they inform me that I will be taxed 20% for the first 4 months I work there. I did this for the first 4 months I was in Taiwan 5 years ago and have never had to do this since. The job I got this summer had no such rule. Anyone know about this policy? Is there a new rule? I was planning on taking this job for a few months then going home for good, but if this is the new policy in Taiwan I will go home this month. Can someone clarify if this is indeed the norm now in Taiwan.

yes, yes and yes…there is a long thread on this somewhere already.

but you get it all back

Although I’m noticing that compliance is spotty. Some companies are following the new rule to the letter, while others are doing whatever.
