为什么在海外购买的商品需要支付销售税?

why do I pay GST on things I bought while on overseas trips?

That's because the Goods and Services Tax (GST) is a tax on local consumption, not local purchases. That means that the GST is levied on goods consumed in Singapore, whether or not they are bought overseas or in stores here.  

This has been the case since the GST was first introduced on 1 April 1994. The practice is consistent with countries that levy a GST (also known as Value-Added Tax in some countries). - See more at: https://www.gov.sg/factually/con ... thash.tSSIQKNq.dpuf

都有的。淘宝运过来的东西都有。不过还是便宜很多。

其实就是说和国内的增值税一个意思咯。政府的意思是，你买oversea的东西不加税，你让人家本地卖东西的怎么活
