In the Netherlands costs for a flight training would be considered 'negative income'. If you spend 100,000Eur, you can get this back via Tax, so you wont be paying any tax untill you have reached the 100,000 but you would still have to pay the interest.
This system does not exist in Honk Kong I assume ? If it does, Cathay is not paying Anything for your training at all.
Titan, you say you will get the tax back the next year ? So you will get 165.000*2=330.000HKD back ? Or only 165.000 ? How does this work then ? Do you need to earn enough to pay 165.000 in tax that year in order to get it back, or will they just deposit it ?
