The pass including the HSR is only available for foreign tourists:
Can Taiwanese nationals use the Taiwan PASS?
The Taiwan PASS includes a 3-day unlimited Taiwan High-Speed Rail pass, is exclusively for use by foreign tourists. Taiwanese nationals are not able to use it.
Not sure about A(P)RC holders.
well, all about your condition of stay. A(P)RC holders r not tourists. Will they check about it? Maybe not.
Should foreign residents grift on it? they shouldn’t, but I gave up on the griftiness of many here.
According to tax bureau A(P)RC holders are not domiciled in Taiwan. You have been a tourist all along 
Haha, would love to use that logic man! Spot on though!
oh nice, I’m really liking all these tourist packages they’re launching.
As an aside, I wish they’d promote the eastern coast more - its hands down the most beautiful part of the island.
