hagwon,
i dont doubt that you know what tou are talking about. can you tell me what is meant by adjusted income? is this the amount i take home each month after deductions or another figure all together. if i am supposed to pay 15% tax on my take home wage, as quoted previously this is a lot of money, in the region of 300,000 won. not, the 200,00 per year or even the 50,000 per month that others are quoting.
