Tell your maid that it is none of her business (sorry so rude), it is not her income tax, it is Employees Retraining Levy.
We pay that because of we hired you (overseas maid) instead of our local people, so that we need to pay the levy to the HK Gov for the expense of retraining our local HK low income people.
The correct name should be 僱員再培訓徵款 not 僱傭稅.
我鐘意你同我講 I Love U, I Love U Too!
You are the sunshine of my life. That's why I'll always stay around. You are the apple of my eye. Forever you'll stay in my heart.
