Sorry for this inconvenience.
As you might know, I am Jones Lang Lasalle(JLL) staff like Kay NG(Hong Kong) and Jaruwon Abel(Thailand).
I’ve double checked with JLL Korea finance team regarding the tax claims and they said it is impossible to reimburse the money from Expedia if I pay it with my cash since it is Expedia TAX.
I might request it to Expedia Korea staff to pay it with their money and reimburse through concur but it might be strange for them since it is not related to their work.
I’ve double checked with DHL whether it can be paid by the sender, Expedia Thailand as Duty&Tax Paid(DTP) and they confirmed yes if I inform them below.
