Tax exemption on payments
Learn how to set the tax-free amount when requesting a payment.
This guide is intended for businesses who sell tax-free products and services as stipulated in Article 26 of the VAT Act (Supply of Tax-Free Goods or Services).
If you are a general business that does not sell the goods or services specified in this article, you may skip this guide. A 10% VAT is automatically applied through the PG or credit card company for such businesses.
If you are a tax-free business, you can submit a business registration card to prove your tax-exempt status when signing a PG contract. You will receive a merchant ID that allows you to set the following tax-free related properties when requesting a payment using
IMP.

Some PGs use a single merchant ID, without getting a separate tax-free merchant ID, for both taxable and tax-free amounts. They set the
tax_free
property to indicate the tax-free portion of the order.Merchant ID
The name of the merchant ID issued after applying for and signing a PG contract varies by PG. For example, the merchant ID for KG INICIS is
Merchant ID (MID)
, Kakao Pay is Member Code (CID)
, and Naver Pay is Partner ID
.Tax-free merchant IDA tax-free merchant ID is issued to businesses that only sell tax-free products and services. If you make a transaction with a tax-free merchant ID, all payments are tax exempted regardless of thetax-free
setting.
Taxable merchant IDA taxable merchant ID is issued to businesses that only sell taxable products and services. If you make a transaction with a taxable merchant ID, all payments are taxed regardless of thetax-free
setting.
Combination merchant IDA combination merchant ID is issued to businesses that sell both taxable and tax-free products and services. You must use a combination merchant ID to set the tax-free amount for only the tax-free items.To pay for both taxable and tax-free items, specify the total payment amount for all items in theamount
property, and the total tax-free amount for only tax-free items in thetax_free
property.
tax_free
is requiredFor transactions using combination merchant ID, you must set both the
amount
and tax_free
properties. If the tax_free
value is missing, an error may occur when you attempt to open the payment page for some PGs.Note that KG Inicis processes all payments as tax-free; if you change to a combination merchant ID while using a taxable merchant ID, all previous taxed payments are converted to tax-free payments.
The scenarios in this section show how to set the
amount
and tax_free
properties when purchasing tax-free and/or taxable items. Assume that a flower business (tax-free business) sells tax-free plant seedlings and taxable vases as follows:
- Plant seedlings: tax-free, 11,000 won each
- Vase: subject to VAT, 22,000 won each
For a purchase of one seedling, set the total payment amount to 11,000 won, and the total tax-free amount to 11,000 won as follows:
JavaScript
IMP.request_pay({
amount: 11000, // total payment amount
tax_free: 11000, // total tax-free amount
...
}, function (rsp) {
...
});
In this case, the total amount of 11,000 won is tax-free, and the final payment is calculated as follows (terminology may vary by PG):
- Total tax-free amount: 11,000 won
- VAT: 0 won
For a purchase of one vase, set the total payment amount to 22,000 won, and the total tax-free amount to 0 won as follows:
JavaScript
IMP.request_pay({
amount: 22000, // total payment amount
tax_free: 0, // total tax-free amount
...
}, function (rsp) {
...
});
In this case, a 10% VAT is applied to the total amount of 22,000 won, and the final payment is calculated as follows:
- Total item price: 20,000 won
- VAT: 2,000 won
For a purchase of 3 seedlings and 1 vase, set the total payment amount to 55,000 (33,000 + 22,000) won, and the total tax-free amount to 33,000 won (for seedlings) as follows:
JavaScript
IMP.request_pay({
amount: 55000, // total payment amount
tax_free: 33000, // total tax-free amount
...
}, function (rsp) {
...
});
In this case, a 10% VAT is applied to the total taxable amount of 22,000 won, and the final payment is calculated as follows:
- Total item price: 20,000 won
- Total tax-free amount: 33,000 won
- VAT: 2,000 won
