Who This Is For
Built for people who don't need monthly bookkeeping, but do need expert help at filing time.
Foreign Residents in Korea Can Use This Too
If you've lived in Korea 183 days or more and are classified as a tax resident, you must file comprehensive income tax every May in May, just like Korean nationals, regardless of nationality. Foreign instructors and freelancers under 3.3% withholding, foreign employees with side or rental income beyond their wages, and international students with part-time earnings can all have their filing handled through this service.
Consult Without Language Worry
Your Korean doesn't need to be fluent. You can message us on KakaoTalk in plain text, and this page itself is available in English, Japanese, and Chinese. For a fuller picture of tax topics for foreigners, see our Foreigner Tax Guide.

Missed Something on Last Year's Return?
Even if you already filed, you can often get a retroactive refund through a request for reassessment, covering deductions or credits missed over the past 5 years. Whether you filed it yourself or through someone else, it's worth having it reviewed.
Retroactive Refunds via Request for Reassessment
If you missed applying for a tax credit or deduction, or didn't fully reflect your expenses when you filed, a request for reassessment lets us review your past filing again.
