On August 10, 2026, the Korean National Tax Service issued a formal announcement detailing targeted tax support measures for individual and corporate taxpayers residing in areas designated as special disaster zones following record-breaking rainfall and widespread flooding during the preceding month. The announcement specifically addresses the tax obligations of affected taxpayers who experienced property damage, loss of income, or temporary business interruption due to the natural disaster, providing a structured framework for relief that includes deadline extensions, penalty abatements, and specialized guidance for accurate reporting of disaster-related losses. The NTS emphasized that the measures are not merely administrative conveniences but are legally grounded in the Framework Act on Tax Administration, which empowers the agency to grant discretionary relief in circumstances involving force majeure and other unavoidable events that prevent normal tax compliance.
Key Takeaways
- Automatic Extension of filing and payment deadlines for income tax, VAT, and other statutory obligations: The NTS confirmed that all taxpayers whose primary residence or business location is situated within the officially declared flood-disaster zones will receive an automatic extension of 60 days for filing and payment of all tax liabilities that were due between July 1, 2026, and August 31, 2026. The extension applies without the need for a formal application, and no late-payment interest or underreporting penalties will accrue during the extended period. The measure covers both individual income tax returns and corporate tax filings, as well as value-added tax (VAT) periodic returns, ensuring comprehensive coverage across the most common tax obligations faced by natural persons and business entities alike.
- Procedures for Claiming Disaster-Related Tax Deductions and Credits: The announcement detailed specific provisions allowing affected taxpayers to claim additional deductions for unreimbursed casualty losses exceeding the statutory threshold, as well as special tax credits for expenses incurred in the restoration of damaged property and equipment. Taxpayers must submit a supplementary declaration along with substantiating documentation, including but not limited to insurance claim settlements (net of reimbursements), contractor invoices for repair work, and official disaster recognition certificates issued by local mayoral offices. The NTS clarified that losses deductible under these provisions are subject to rigorous review, and taxpayers are advised to maintain meticulous records of all disaster-related expenditures for a minimum period of five years to withstand potential scrutiny during future audits.
- Special Installment Payment Arrangements for Outstanding Tax Liabilities: Recognizing that many taxpayers may face liquidity constraints even with the deadline extension, the NTS introduced a special installment payment program allowing eligible taxpayers to spread outstanding tax balances over a maximum of 24 monthly installments without incurring additional penalty charges. The program is automatically available to all taxpayers in the designated zones, though applicants must declare their current financial hardship and provide a brief statement of income and expenditure. The NTS stated that the installment terms are flexible and can be adjusted upon re-evaluation of the taxpayer’s financial situation, providing a critical safety net for small business owners and individual taxpayers recovering from the disaster’s economic impact.
