Sole Proprietors' VAT Preliminary Notice: If the Amount Is Below KRW 500,000, Is Payment Required in October? Preliminary Notice vs. Preliminary Return
If the October 2026 VAT preliminary notice amount for an individual business owner subject to general taxation is below KRW 500,000, the business owner is excluded from the preliminary notice requirement and does not have to pay that preliminary notice amount in October. However, this does not mean the tax itself is eliminated. Business results for 7–December of 2026 will be reported and settled in the final VAT return for the 2 tax period, filed in January 2027. This is where one of the most common misunderstandings arises.
