如何退税
如果买家符合免税条件，他们可以申请退税。根据此处的买家帮助内容，买家将直接向您（即卖家）请求这些退款。
要处理退税，请执行以下操作：
在管理订单中找到淡定，然后在【订单详情】页面中点击【订单退款】。
在【订单退款】页面顶部，点击【仅退税】。
重要： 除非订单由亚马逊配送或税费由亚马逊管理，否则您将不会看到【仅退税】按钮。请参阅以下部分，验证您订单的配送方式和征税义务。
选择【免税买家】或【非法人地区的订单】。
对于【免税买家】，请选择豁免原因。
对于非法人地区的订单，请选择一个或多个您将退款的司法辖区。
点击【提交退款】。
验证订单的配送方式和征税义务
如果您只能发放退款而无法发放税费，请核实订单是否由亚马逊配送，或是否配送到了由亚马逊管理税务计算、收取、代缴和退款的州。
要查看配送方式和征税义务，请执行以下操作：
如果配送方式为“亚马逊”或者备注内容为“税务由亚马逊管理”，您可以将买家移交给亚马逊客户服务。
如果配送方式为“卖家”且备注内容为“税务由卖家管理”，则由您来承担发放退款的责任。

How to refund tax
If a buyer qualifies for tax exempt status, they can request a tax refund. Buyers will request these refunds directly from you, the seller, according to the buyer Help content here.
In order to process a tax refund:
Find the order in Manage Orders and click Refund Order from the Order Details page.
At the top of the Refund order page, click Refund tax only.
Important: Unless the order was fulfilled by Amazon or tax is managed by Amazon, you will not see the Refund tax only button. See the following section to verify your Fulfillment method and tax collection obligation for an order.
Select Tax exempt buyer or Order from an unincorporated area.
For Tax exempt buyer, choose an exemption reason.
For Order from an unincorporated area, choose one or more of the jurisdictions that you will refund.
Click Submit refund.
Verify your Fulfillment method and tax collection obligation for an order
If you are unable to issue a tax only refund, you can verify if the order was fulfilled by Amazon or shipped to a state where Amazon manages tax calculation, collection, remittance, and refunds.
To check the Fulfillment method and tax collection obligation:
Go to the Manage Orders page.
You should see one of the following options: Amazon or Merchant.
In the Manage Orders page, check if there is a note next to the tax stating ‘tax is managed by Amazon’ or ‘tax is managed by Merchant’.
If the fulfillment method is Amazon or the note states ‘tax is managed by Amazon’, you can refer the customer to contact Customer Support.
If the fulfillment method is Merchant and the note states ‘tax is managed by Merchant’, the responsibility remains with you to issue refunds.
For more information regarding who handles a customer tax refund on orders, see the Marketplace Tax Collection FAQ.
