The easiest way for foreigners to check income tax payments and claim their tax return in Korea is through SamJjeomSam (์ผ์ฉ์ผ). With simplified Kakao verification, you can easily claim your income tax returns.
Introduction
There are a couple of different ways to check your Korean income tax and file returns. Normally, Koreans check their income tax through the app โHome tax โ. However, foreigners will have difficulty with authentication (๊ณต๋์ธ์ฆ์ ). You will find that you cannot verify your information either because of your ID number or because you do not have a legal Korean name.
Thankfully, SamJjeomSam (์ผ์ฉ์ผ) uses Kakao to verify your identity so as long as you have your Kakao account setup properly you should not have any issues. With that in mind, you do need to be a legal resident with a valid ARC, Korean bank account, and phone number for your Kakao account to be used as verification.

My friend got her tax declared without knowing. Luckily, after checking and speaking with her boss, the declaration was removed. For people who work more than their visa allows, even if they did it before regulations changed, removing the tax declaration is necessary to renew your visa.
