I heard last year taxes were going up on foreigners (rumors of 15%), but it's really not that bad.
Here's what I can deduce from my tax document I received today. Disclaimer: I am no expert.
As far as income goes, I have no idea if housing, bonus renewal, or severance is taxed.
I can see the first 11,010,000 won is not taxed. (poverty line?)
Here are then 5 categories of deductions used by my public school's accountant:
기본공제 The basic exemptions - 본인 - self, 배우자 - spouse, and 부양가족 dependents
1,500,000 for self. No idea for spouse or dependents
추가공제 Additional deductions - 경로우대 Senior, 자녀양육비 Child Support, 장애인 Disabled, 출산 Childbirth, 입양자 Ipyangja, 부녀자 Women, 다자녀추가 Additional multilateral and women. I have no idea what the last 3 are.
특별공제 Special deductions - 보험료 Premium, 주택자금 Mortgage, 표준공제 Standard deduction, 의료비 Medical, 기부금 Donation, 교육비 Tuition
기타공제 Other deductions - 연금저축 Pension savings, 국민연금보험료 National Pension Insurance, 투자조합출자 Investment Fund, 장기주식형저축 Long-term Equity Savings
The majority of foreign English teachers will only qualify for the "self" deduction. From there, married couples, children, medical expenses, tuition for those attending university in Korea are likely to be common deductions.
My school deducted about half my taxes through the course of the year. Tomorrow they'll take out the rest (350,000). I fell in the 6% bracket - I have no idea what the percentages are for different income brackets. I was able to claim my tuition and saved at least 300,000 won. It's possible I would have fallen in a higher tax bracket.
For those of you thinking of trying to deduct everything, keep in mind that I spent 5,000,000 on my tuition. Spent 5m to save 300k. I've spoken to a lot of university professors who've lived here long term and even with some high medical expenses it never made sense for them to do the tax card accounting because they simply don't spend enough. I'd wager that for all 30-50,000 English teachers in Korea, that the tax card might be worth the effort for those already taking a lot of deductions (child support, health care), but they would be on a super tight budget... not the kind of lifestyle that would keep many here.
I'm happy that my school's accountant files this
