5 Tips for Filing your Taxes in Korea for Foreigners

1. Find out whether you even have to file your taxes in Korea.

If you are a salaried employee for a company in Korea, most likely your company will file your taxes on your behalf. Therefore you need to find out if you are a salaried worker or a freelancer (independent contractor). There have been many cases where Korean English teachers who thought they were salary employees ended up being independent contractors. After 2 years, the Korean government contacted them with a huge bill for unpaid taxes. Therefore find out if you are an independent contractor. What are some clues that you are an independent contractor in Korea? 

Clues you are an independent contractor in Korea

  1. You are paying only 3.3% in taxes. 
  2. No health insurance coverage. 
  3. You don’t get severance pay.

2. Collect all your payslips.

Now that you know you are an independent contractor or have a company in Korea, the next step is to make sure you keep all your payslips. If you didn’t, don’t worry too much because Korea has a tax platform called HomeTax. There you will find a section called MyNTS which will have all your payslips. If you are an English teacher in Korea, ask your school to give you a Wage Earner Income Statement. This is your end of the year pay stub that will show your gross income and withheld taxes. This document will also show how much money was taken out of your pay for pension and health insurance. Or you can go to a local tax office and request a Certificate of Income.

3. Did you make under 15 million won last year?

If you made under 15 million won the tax process is very easy. Just take your ARC card to any tax office in Korea and they will guide you through your tax process via their stationed computer. There is no reason for you to hire a tax accountant. However, if you made over 15 million won, check out the next steps below. 

4. Did you make over 15 million won last year?

For those that made over 15 million won. Ask yourself, do I have any deductibles? What qualifies as deductibles? Are you single? Do you have dependents? All these will factor into how much taxes you will end up paying. It is up to the employee to provide their own deductions to maximize their refund. Hometax offers a tax refund calculator which shows you how much you will get back on your tax return.

Deductibles could include:

  • Travel expenses
  • Supplies 
  • Political donations

3.3% is taken from your gross income. However, in around 70% of the cases, based on a person’s deductibles, they will get some money back from the tax office. Most English teachers in Korea get money back from the tax office.

5. Do you want to hire a tax accountant or file your own taxes in Korea?

If you want to hire a tax accountant in Korea, do your research. Find a tax accountant that will handle the paperwork for you. Then all you need to do is provide the documents and information and the tax accountant will take care of the rest. Prices can vary but if they are asking for over 1 million won for filing your single income taxes in Korea, you are paying too much.

If you are looking to file your own taxes you will need to go to your nearest NTS (National Tax Service) office with your paystubs from your employer or the tax office. Remember to bring your ARC card. The public official there will take your ARC card and your paystubs and input the information into a computer. They will then let you know how much you owe in taxes. You will be able to pay the amount there.
