There is no single place to check all your tax and insurance arrears at once. Here's a collection of where to check.
📌 Key points
National tax: Hometax; local tax: Wetax; health insurance: National Health Insurance Service; national pension: National Pension Service — these are four separate places. If you're approaching a stay extension, you need to check all four.
📍 Where to go
National tax: relevant tax office · 126; local tax: city/county/district office · 110; health insurance: 1577-1000; national pension: 1355.
National tax can be checked on Hometax (hometax.go.kr). Both sites are in Korean only. Foreigners can sign up for Wetax too. However, simple authentication like Naver or Kakao is not available — sign-up and login only work with a public certificate or financial certificate, according to Wetax's FAQ. If you don't have a certificate, you can use "Quick Payment" on the homepage with the electronic payment number from your bill to pay without logging in, or you can go to your city/county/district office. When entering your name, it must be in capital letters exactly as on your passport, including spacing, or the search will fail. Service hours are not 24 hours either — electronic civil service is 06:00–24:00, and payment is 00:30–23:30.
⚠️ Things to watch out for
Even if you're behind, you don't need to pay it all at once. The National Health Insurance Service (1577-1000) and tax offices can guide you toward installment payment. "Doing nothing" is worse than the amount itself — call first and explain your situation.
❗ What happens if you don't
Arrears affect a broad range of immigration matters, such as extending your period of stay, changing your status, or changing your workplace. And in naturalization screening, "failure to pay national tax, customs duty, or local tax" is listed in the rules as a reason that may be treated as not having good conduct.
