For many individual business owners in South Korea, the Onnuri gift certificate is a seductive tool for saving money. With discounts often available at the point of purchase and a mandate to support traditional markets, these vouchers seem like a financial “no-brainer.” However, when tax season arrives, a recurring point of confusion emerges: can the purchase of these certificates be written off as a business expense on a comprehensive income tax return?
The short answer is no—at least not at the moment of purchase. While it is a common misconception that buying Onnuri gift certificates with a corporate or personal credit card creates an immediate tax deduction, the South Korean tax system views the transaction differently. For the individual business owner, buying a gift certificate is not an expenditure; it is an exchange of one asset for another.
Understanding the distinction between 개인사업자 온누리상품권 비용처리 (expense processing for individual business owners) and the income deductions available to salaried employees is critical. Misclassifying these transactions can lead to discrepancies during a National Tax Service (NTS) audit, potentially resulting in unexpected tax liabilities.
The Asset Swap: Why Purchase Costs Aren’t Immediate Expenses
From an accounting perspective, purchasing a gift certificate is essentially moving money from a bank account (or a credit line) into a “voucher” account. Because the business owner still holds the value of the money—just in a different form—no actual “cost” has been incurred to the business yet. The act of buying the certificate cannot be claimed as a direct expense for comprehensive income tax purposes.
This differs significantly from buying office supplies or paying rent. In those cases, the money is gone in exchange for a service or a physical product used for business. With Onnuri certificates, the “expense” only occurs when the certificate is actually spent at a merchant to acquire goods or services necessary for the operation of the business.
For those using credit cards to acquire these vouchers, the credit card slip serves as a record of the acquisition. While this slip is a “qualified evidence” (적격증빙) document, it proves that you bought the voucher, not that you spent the money on a business-related cost. The actual tax benefit is deferred until the moment of redemption.
Who Actually Benefits from the 40% Income Deduction?
Much of the confusion stems from the widely publicized 40% income deduction for spending at traditional markets. It is vital to clarify that this specific income deduction (소득공제) is a benefit reserved exclusively for wage earners (근로소득자) who file a year-end tax settlement.
Individual business owners operate under a different tax regime. Instead of “income deductions,” they focus on “necessary expenses” (필요경비). While a salaried employee uses the deduction to lower their taxable income bracket, a business owner subtracts the actual cost of doing business from their gross revenue to determine their taxable profit.
| Feature | Wage Earner (Employee) | Individual Business Owner |
|---|---|---|
| Primary Benefit | Income Deduction (소득공제) | Necessary Expense (필요경비) |
| Traditional Market Benefit | Up to 40% deduction on spending | Deductible if used for business costs |
| Timing of Benefit | Year-end settlement | Comprehensive Income Tax filing |
| Evidence Required | Credit card/Cash receipt records | Qualified evidence (Tax invoice, etc.) |
How to Legally Claim Expenses Using Onnuri Certificates
While the purchase itself isn’t deductible, the spending of the certificate can be. If a business owner uses an Onnuri gift certificate to buy materials, office supplies, or other items essential to their trade, that expenditure is a legitimate business expense. To ensure this holds up under scrutiny, the business owner must follow a specific evidentiary trail.
First, the expenditure must be genuinely related to the business. Using a certificate to buy a personal meal or household groceries will not qualify. Second, the owner must obtain a qualified receipt from the merchant where the certificate is spent. This could be a cash receipt (현금영수증) issued to the business registration number or a formal tax invoice.
The timeline for this process is key:
- Step 1: Purchase. Buy the certificate via credit card. (No tax deduction here).
- Step 2: Usage. Use the certificate to buy a business-related item.
- Step 3: Documentation. Request a business cash receipt from the merchant at the time of usage.
- Step 4: Filing. Report the cost of the item as a necessary expense during the May comprehensive income tax filing period.
In this scenario, the credit card slip from the initial purchase serves as secondary proof that the funds used to buy the item were legally acquired, but the merchant’s receipt is the primary document that triggers the tax deduction.
Strategic Considerations for Business Owners
For those looking to optimize their tax position, the most effective strategy is meticulous record-keeping. Because Onnuri certificates are often used in traditional markets where formal invoicing can be less common than in corporate retail, business owners should be proactive in requesting cash receipts.
It is also worth noting that using a credit card to buy the certificates allows the business owner to maintain a digital paper trail of the original fund source, which is helpful if the Small Enterprise and Market Service (SEMAS) or tax authorities ever query the origin of the funds used for business purchases.

As the next comprehensive income tax filing window approaches in May, business owners should review their voucher spending from the previous year. Ensuring that every Onnuri-funded business purchase is backed by a business cash receipt will be the difference between a missed opportunity and a successful tax optimization.
