    South Korea Annual Compliances


    Corporate Tax Filing (Mandatory)

    The company’s taxable income is imposed with corporate income tax as specified by the National Tax Guideline in South Korea.

    For South Korean resident corporations, the company will be taxed on their income from outside and inside the country.

    Meanwhile, for non-resident South Korean corporations, the company will be taxed toward its Korean-based income only.

    The deadline for the income tax report is based on the fiscal year specified in the company’s Article of Incorporation. However, the fiscal-year date cannot exceed 12 months. The fiscal year extends from January 1st to December 31st.

    Quarterly VAT Filing (Mandatory)

    All South Korean incorporated companies must file periodic VAT returns detailing all taxable supplies (sales) and inputs (costs).

    The VAT filing return deadline in Korea is 25 days from the period’s end, and any associated VAT liability must also be paid by this deadline. In the event, the company has a tax credit (where the VAT incurred by the company exceeds the VAT charged on its sales in the reporting period), approved credits will be paid over to the company within 30 days of the return deadline.

    Annual Audit (exemptions applicable)

    A limited company (Yuhan Hoesa) is subjected to an external audit if the company meets 2 out of 3 conditions as follows:

    • total assets more than KRW12 billion (US$8million)
    • total liabilities more than KRW7 billion (US$5million)
    • revenues are more than KRW10 billion (US$7million)

    To comply with the external audit, the company must appoint an external auditor from any certified Korean Public Accounting Firm.
