Understanding how to manage your VAT efficiently can lead to meaningful savings for your business. This article explores the essential points related to purchases that can help you minimize your VAT tax obligations legally and effectively.

Proper Invoice Issuance

One of the fundamental aspects of managing VAT in Korea is ensuring that invoices are issued correctly and timely. For instance, general taxpayers(일반 과세자), including simplified taxpayers(간이 과세자) from the yaer 2021, are required to issue invoices when supplying goods or services liable to VAT. Mistakes in invoice issuance can lead to unnecessary penalties for the supplier and the purchaser, potentially disrupting business relationships.

Why Implement a Tax Invoice Syetem?

The primary reason for implementing a tax invoice system in Korea is to ensure that invoices are issued at the time of supply. While issuing an invoice before the supply date is permissible, failing to issue one before the due reporting date of the relevant tax period can result in penalties. For instance, if an invoice is delayed beyond the tax period’s reporting deadline, both the supplier and the recipient can incur penalties of 1% and 0.5% of the supply value, respectively.

Mandatory Information on Tax Invoices

If mandatory details are incorrectly filled or omitted on a tax invoice, penalties may arise. These details include:

It’s crucial to ensure tax invoices are completed accurately to avoid these penalties.

Understanding When Input Tax Is Not VAT Deductible

Input tax refers to the VAT a business pays on goods and services it purchases for use in its operations, which can be deducted from the VAT it charges on its sales. However, there are cases where input tax cannot be deducted:

  1. Lack of Proper Documentation: If a business fails to submit a purchase ledger or submits incomplete or incorrect information, the input tax for such transactions cannot be deducted unless corrections are made through appropriate channels.
  2. Incorrect Tax Invoices: If an invoice lacks essential information or includes incorrect information, the related input tax cannot be deducted.
  3. Non-Business Related Expenditure: Expenses not directly related to business activities, such as entertainment expenses or personal use assets, cannot be claimed as deductible input tax.
  4. Purchase of Business Vehicles: Expenses related to the purchase or leasing of certain vehicles for business use are not deductible, except for specific industries like transportation services.

Importance of Verifying Business Status

Before entering into transactions, especially with new vendors, it is vital to verify the business status of the counterpart. Engaging with businesses that have ceased operations or are using fraudulent invoices can result in non-deductible input tax.

Please ensure that the business providing the invoice is a registered and operational entity. This verification can often be performed through official tax or government websites that offer business status checks.
