❓ 자주 묻는 법정 질문 (FAQ)
What is the National Tax Service (NTS) Simplified Tax Table (근로소득 간이세액표)?
The Simplified Tax Table published by the National Tax Service (국세청) prescribes the statutory monthly income tax withheld from an employee's salary. It factors in basic deductions, earned income deduction, and progressive income tax rates (6% to 45%) along with family size, before final year-end tax settlement (연말정산).
What are the individual income tax brackets in South Korea?
The progressive tax brackets under Article 55 of the Income Tax Act are: (1) Up to KRW 14M: 6%; (2) KRW 14M to 50M: 15%; (3) KRW 50M to 88M: 24%; (4) KRW 88M to 150M: 35%; (5) KRW 150M to 300M: 38%; (6) KRW 300M to 500M: 40%; (7) KRW 500M to 1B: 42%; (8) Over KRW 1B: 45%.
What is Local Income Tax (지방소득세) and how is it calculated?
Local Income Tax is a municipal tax levied under the Local Tax Act at a flat rate of 10% of the calculated national earned income tax liability, paid concurrently to the local district tax office.
Can employees adjust their monthly withholding tax rate in Korea?
Yes. Under the Income Tax Act Enforcement Decree, an employee can submit a formal application to their employer to adjust their monthly withholding tax to 80%, 100% (default), or 120% of the standard Simplified Tax Table amount to manage their cash flow and year-end refund expectations.
How do dependent children affect monthly earned income tax withholding?
Under the Simplified Tax Table, qualifying dependent children aged 8 to 20 grant an additional tax credit deduction, significantly lowering monthly tax withheld compared to single taxpayers with identical salaries.
