If you don’t have it right now, you can fill the field with 13 nines. (e.g. 9999999999999). The system moves on the next phase without it. However, it is recommended to update it in the near future.
The total VAT amount can be determined as 10% of the Amount subject to settlement. ONE store pays the VAT to the Korean’s National Tax Service instead of the international sellers because it’s very difficult to pay it by themselves. It is automatically deducted from the payments for sellers. You can check it on your monthly settlement statements.
If your bank account number was identified as a wrong number, the banks keep the payments temporally. If such a situation happened, ONE store can request sellers to update it to another one. (see FAQ 1-1). Once the new bank information updated, ONE store can retry the payment. In this case, the return and retrial fees can be deducted from the original amount.
ONE store pays the sending fees for the international payment transactions. However, some banks charge additional fees to the receivers. We've found some cases that there are more than one banks exist for one international payment request. ONE store pays the first sending fees to the first banks, however, we cannot pay the next transaction fees to the second banks. Please understand such complicated situations.
'The discounted amount from the coupon, points, and carrier membership will not be appiled to the final VAT amount calculation since Onestore's new rule of the fee calculation method which is influenced by the Korean VAT law change.
ㆍ Legal basis: It is based on the new Korean VAT law. (judicial precedent of Gmarket case #2014두 298, 23th, Jun, 2016)
ㆍ The all developers or sellers who receive the fee invoice from ONEstore.
ㆍ Nothing changes..
ㆍ In order to ensure that developers can file VAT returns by applying revised laws and related rulings, ONEstore introduced the concept of "the amount subject to settlement" and applied it to the "Payment and Financial Report" page.
ㆍ The Amount subject to Settlement is the sales amount net of customer coupon/points/membership,etc. uses.
Based on the VATL revision in February 2017 and the Supreme court ruling related to other open market case, developers have to report in their VAT returns the amount subject to settlement, which is the sales amount net of coupon/point/membership uses, etc.; whereas ONEstore has to do so the commission amount, minus coupon/point/membership uses, etc.
ㆍ Developers have to report the following amounts in their tax returns.
1) Sales VAT amount : VAT included in the amount subject to settlement*
2) Input VAT amount : VAT included in commissions*
*) Amount net of coupon/point/membership uses, etc.
ㆍ The payment to developers remains unchanged.
ㆍ The Amount subject to Settlement refers to the 'supply price', the sum of sales amount and sales tax liability reported on VAT returns. It is different from sales amount recognized under accounting standards as it is governed by different laws.
It is necessary to decide internally, supported by accounting professionals whether sales are recognized on P/L based on sales amount or the amount subject to settlement (the sales amount net of coupon/point/membership uses, etc.).
For reference, the payment made to developers remains unchanged even after the deductions of coupon/points/membership uses, etc..
ㆍ ONEstore issues a tax invoice for commissions net of coupon/points/membership uses, etc. which reduces input tax as much. Nonetheless, if you file sales VAT returns based on the sales amount as before, it will increase tax burden since more amount as much as coupon/points/membership uses is reported for tax.
Thus, you are advised to file VAT based on the changed <Amount subject to Settlement>.
ㆍ The amount deducted as much as coupon/points/membership uses, etc. is determined, not in excess of the commission for relevant sales amount. In other words, for coupon/points/membership uses, etc. in excess of commission for relevant sales amount, minus (-) tax invoice is not issued.
ㆍ Commissions based on sales are the same as before. The ultimate commissions charged to developers are the aforementioned commissions based on sales, subtracted by coupon/point/membership uses, etc. Based on this commission amount actually charged to, ONEstore issues a tax invoice.
As coupon/points/membership deductions are done both from a developer's sales amount and from ONEstore commissions based on sales amount, the payment made to developers remains the same.
ㆍ Like the amount subject to settlement separated from sales amount, commissions are different from developers' costs in terms of concept. It is necessary to decide internally, supported by accounting professionals, whether costs will be recognized, net of coupon/point/membership uses, etc
ㆍ It is the amount paid by customers using ONEstore event discounts (coupon/point) or membership service (T/KT/U+). Even after these deductions from sales amount and commissions, the payment made to developers remains unchanged.
ㆍ You can see the details of coupon/point/membership uses by App on excel downloaded from Payment and Financial Report.
ㆍ The payment made to developers is the same, but the deduction method differs by service provider (telecommunication service provider). For ONEstore, all the uses of coupon/points/membership are deducted, whereas for KT and LG Uplus, part of coupon/points/membership uses is subtracted.
ㆍ Like domestic developers, VAT is paid by proxy, based on the amount net of coupon/point/membership uses, etc. The payment to overseas developers remains the same.
ㆍ Withholding tax is calculated based on the sales amount net of customer coupon/point/membership uses, etc..
ㆍ The payment remains the same as it does for domestic developers.
ㆍ The rule for VAT is differ from the carriers of purchasing user, and identically applied for individual purchase transaction.
Below is the example for the VAT calculation that assumes 20% of user payment and 50% of point discount are base of the market fee, which has applied since Jul 1st, 2018. It also shows the case that the point discount is under or over the market fee amount
ㆍ Selling on the ONEstore storefront
(2) Deduction: When the fee based on the price (\2500) is greater than the point discount (\1,100), Onestore deducts the whole amount of point discount from the market fee.
ㆍ Selling on the KT or U+ storefront
(2) Deduction: KT and U+ deduct the sum of the fee based on the price (\500) and it’s VAT (\50). Furthermore, the deduction should not exceed the fee of the point discount including it’s VAT.
ㆍ Selling on the ONEstore storefront
Deduction: When the fee based on the price (\5,000) is smaller than the point discount (\6,600), ONEstore deducts the sum of total fee based on the price (\5,000) and it’s VAT (\500).
ㆍ Selling on the KT or U+ storefront
(2) Deduction: When the fee based on the price (\5,000) is smaller than the point discount (\6,600), KT and U+ deduct the sum of the partial fee based on the point discount amount (\3,000) and it’s VAT (\300). Furthermore, the deduction should not exceed the fee of the point discount including it’s VAT.
