Revision scheme of tax paid alleviates the financial burden of companies

The revision scheme ensures stable business operations via the early determination of the amount of customs duties

Where a taxpayer makes an amended declaration for deficient customs duty after a post-audit, he/she would have to pay additional duties and may be subject to penalties. This is why the self-revision system exists to support stable business activities and ease the business burden by enabling early determination of the amounts of revised duties.

Revision, Amendment, and Claim for rectification may be used to declare changes in duty amounts. Each scheme is applied based on the time period of filing application.

• In case of deficiency in customs duty within 6 months from the date of declaration and payment, →"apply for revision scheme of tax paid."
• In case of deficiency in customs duty after the revision deadline, → "make an amended declaration."
• In case of reporting the over-payment of the customs duty within 5 years from the date of declaration and tax payment, → "request rectification."
