亚马逊税务计算服务
如果专业卖家有义务为其发往美国非商城征税管辖区的订单计算税费（通常被税务机关视为“销售税和使用税”，此处统称为“税费”），则可使用亚马逊税务计算服务。
对于发往商城征税管辖区的订单，亚马逊将负责计算、收取、代缴和退还税费。请参阅我们的常见问题，了解有关商城征税的更多信息。
对于发往美国管辖区且您有义务计算税费的订单，您可以提供您的税务登记号，并使用我们的商品税务代码按可征税性对每种商品进行分类，从而启用我们的服务。您也可以选择通过亚马逊免税计划接受买家豁免。
我们的服务使用买家提供的订单目的地城市、州、邮政编码、订单起运地以及订单验收地点等信息来确定要应用于订单的税率。
我们的服务会计算被标记为消费税或收入总额税（例如，在新墨西哥和夏威夷州）、但通常被视为销售税和使用税的税费。
我们的服务不会计算联邦、州或当地监管费用（酒瓶、电子垃圾、回收）、基于商品的消费税或类似收入总额税（明尼苏达州特别征收的皮草税）或跨境销售税（起运地在美国境外但目的地在美国境内）。
有关亚马逊如何为订单计算税费的其他信息，请查看我们的征税法文件。
注意： 亚马逊税务计算服务和报告仅向已订阅专业销售计划的卖家开放。请务必经常下载纳税申报文件，并将您的记录保存在安全的位置。请参阅降级/升级以及税务计算服务，了解更多信息。
我们的税务计算服务包括用于计算非商城征税管辖区税费的自动更新内容和某些卖家选项：
销售税和使用税的税率由我们的税率提供商 Vertex 自动更新
销售税和使用税的税率按每个管辖区类型（州、县、市、区）计算
针对每件商品计算销售税和使用税（将分别为售出的每件商品计算税费）
用于将可征税性代码（商品税务代码）分配给一种和/或多种商品的卖家选项
在卖家为商品分配可征税性代码时，我们的服务会提供商品税务代码分类，例如服装、图书、食品和电脑等
用于计算当地县、市和区等管辖区税费的卖家选项
用于计算运费、处理费和礼品包装费的税费的卖家选项
用于向非商城征税州分配可选自定义税率的卖家选项
如果您使用此选项，该服务将使用您的自定义税率覆盖分配给您的商品税务代码和我们的税率提供商设定的管辖区税率
该服务将根据自定义税率在州管辖区级别计算您的税费
要使用此选项，您只能分配一个能够准确反映管辖区实际税率的税率
供卖家参与亚马逊免税计划 (ATEP) 的选项
正如我们的税务政策中详细说明的那样，我们会将针对发往非商城征税州的订单计算的所有税费与您的正常收入付款一起支付给您，以便您向各个税务机关缴纳税费。针对您的订单计算的税率和税费管辖区信息等税务计算详情会反映在您的销售税报告中。请参阅卖家报告中的销售税务信息，了解完整详情。
自行配送订单的卖家可以通过“管理订单”页面退还订单税费。亚马逊客户服务团队将管理使用亚马逊物流 (FBA) 配送的订单，但有关税务设置的具体问题将始终由卖家负责回复。
如果您的公司有义务公开提供与纳税义务相关的任何信息，您可以转至“设置”> 您的信息和政策 > 税收选项卡，相应地更新您的卖家资料。
在配置税务设置之前，请务必了解您计算税费的义务以及管理税费计算的责任。有关使用亚马逊税务计算服务的卖家责任，请参阅税务计算服务条款。

Tax calculation services
Amazon’s Tax Calculation Service is available to Professional Sellers who have an obligation to calculate Taxes (commonly acknowledged as “sales and use tax” among taxing authorities and collectively referred to as “Taxes” here) on their orders destined to non-Marketplace Tax Collection jurisdictions in the United States (US).
For orders destined to Marketplace Tax Collection jurisdictions, Amazon will be the tax responsible party to calculate, collect, remit, and refund Taxes calculated. See our FAQ to learn more about Marketplace Tax Collection.
For orders destined to US jurisdictions you have an obligation to calculate Taxes, you may enable our service by providing your tax registration number(s), classifying taxability for each of your products using our product tax codes, and choose to accept buyer exemptions through Amazon’s Tax Exemption Program.
Our service uses buyer provided information such as an order destination city, state, and zip code, order origin information, and order acceptance location to determine the tax rate calculated for an order.
Our service will calculate Taxes that are labeled as excise or gross receipt tax (for example, in New Mexico and Hawaii) that are commonly acknowledged to be sales and use taxes.
Our service will not calculate federal, state, or local regulatory fees (bottle, e-waste, recycling), product-based excise, or similar gross receipt taxes (special fur clothing tax in Minnesota) or Taxes on cross border sales (non-US origin to US destination).
Additional information about how Amazon calculates Taxes on your orders is available in our Tax Methodology document.
Note: Amazon’s tax calculation service and reporting is available to sellers subscribed to the professional selling plan only. It is important to download your tax reporting documents frequently and maintain your records in a safe place. See Downgrade or upgrade and tax calculation service for more information.
Our tax calculation services includes automatic updates and certain seller options to calculate Taxes in non-Marketplace Tax Collection jurisdictions:
Sales and use tax rates are automatically updated by our tax rate provider, Vertex
Sales and use tax rates are calculated by each jurisdiction type (state, county, city, district rates)
Sales and use tax calculations are made for each item (each product sold will calculate individually)
Seller option to assign taxability codes (product tax code) to one and/or many products
Our service offers product tax code categories such as clothing, books, food, computers, etc. for sellers to use when assigning taxability to their products
Seller option to calculate local county, city, and district jurisdiction taxes
Seller option to calculate Taxes on shipping and handling and gift wrap
Seller option to assign an optional custom tax rate to non-Marketplace Tax Collection states
Using this option will override your product tax code assignment and the jurisdiction tax from our tax rate provider with your custom tax rate
A custom tax rate will calculate your custom at the state jurisdiction level
To use this option, you must only assign a rate that accurately reflects the jurisdictions actual rate
Seller option to participate in the Amazon Tax-Exemption Program (ATEP)
As detailed in our Tax Policies, all Taxes calculated on orders destined to a non-Marketplace Tax Collection state are paid to you with your normal earnings disbursement for you to remit to individual taxing authorities. Tax calculation details such as the tax rate and taxed jurisdiction information calculated on your orders are reflected in your Sales Tax Report. See Sales tax information in seller reports for complete details.
The ability to refund Taxes on an order are supported via the Manage Orders page for sellers who fulfill their own orders. Amazon Customer Service will manage orders fulfilled using Fulfillment by Amazon (FBA), however specific questions about your tax settings will always be the sellers’ responsibility to respond to.
If your business has an obligation to make any information about your tax obligation publically available, you may update your seller profile accordingly by navigating to Settings > Your Info & Policies > Tax (tab).
It is important to understand your obligation to calculate tax and responsibilities to manage calculations made before setting up your tax settings. Seller responsibilities related to using Amazon’s Tax Calculation Service are available in the Tax Calculation Services Terms.
