You may get the below tax notice and need to pay it by the end of August.
I need to pay 62,500 won, it's 50,000won resident tax and 12,500won(25% of the resident tax) is for local education tax.
Once a year every individual resident(4,800won), sole proprietor(50,000won) and corporations need to pay this fixed amount of resident tax, A corporation need to pay the resident tax based on sales revenue and no.of employees according to the local tax law article 74-79.
It's not a big money but need to pay on time since it's one of your tax liability in my country.
