商品税务代码
重要： 本页信息不构成税务、法律或其他专业建议，也不得用作此类用途。如有疑问，请咨询您的专业顾问。
税务计算服务要求配置商品税务代码 (PTC) 和管辖设置以便开始计算。
商品可征税性规则因 PTC 而异，且与特定管辖区域相关，如 Amazon商品税务代码列表中所述。可在商品和/或默认级别分配 PTC。
如果未将 PTC 分配到默认级别或商品级别，则在使用“始终非应税”A_GEN_NOTAX 商品税务代码的交易中，商品的税务计算结果为非应税，从而得出零百分比计算。
默认级别： 可在您的税务设置中设置默认 PTC，并用于将分配的单个 PTC 应用于尚未分配特定商品级别 PTC 的多件商品。如果您使用自定义税率，您的 PTC 规则和税率将替换为您的自定义税率。加拿大不提供自定义税率。
要查看或编辑默认商品税务代码，请执行以下操作：
在卖家平台中，前往【设置】。
点击【税务设置】。
在【税务计算规则】下，使用【默认商品税务代码】旁边的下拉菜单。
选择【默认商品税务代码】
使用下拉菜单旁边的查看商品税务代码链接，查看 PTC 完整列表以及与每个 PTC 相关的规则
阅读【征税方法】和【服务条款】，并【选中确认】框
点击【保存设置】
商品级别： 可在商品库存页面中设置商品级别的 PTC，并用于为分配到的特定商品指定特定 PTC。将先使用商品级别 PTC，然后再分配默认 PTC。此外，如果您使用自定义税率，您的 PTC 规则和税率将替换为您的自定义税率。加拿大不提供自定义税率。
要查看或编辑商品级别商品税务代码，请执行以下操作：
前往【管理库存】
点击与单件商品对应的【编辑】
届时将进入【编辑商品信息】页面
在【商品选项卡】中找到“税务代码”字段
点击该字段，并从下拉列表中选择您的【商品级别商品税务代码】
点击【保存并完成】
以下工具可用于协助更新单件商品的详情页面：
要批量编辑多件商品，请使用库存文件上传。
要添加新商品，请使用添加新商品工具。
如何在进行税务计算时确定商品税务代码 (PTC)
如果同时在卖家定义的默认级别和商品级别分配了 PTC，亚马逊将会使用商品级别税务代码。
如果只在默认级别而未在商品级别分配 PTC，亚马逊将会使用卖家定义的默认 PTC。
如果未在商品级别或默认级别分配 PTC，亚马逊将使用非应税 PTC A_GEN_NOTAX 进行计算。
注意： 自定义税率（如配置）将会覆盖 PTC 的可征税性规则，A_GEN_NOTAX 除外。要了解更多信息，请参阅自定义税率。加拿大不提供自定义税率。
税务计算设置更新通常会在 15-20 分钟内生效，不适用于订单追溯。如果您发现税务计算意外，请检查您的设置（税务设置和商品级别）和库存文件上传是否存在错误（如果您使用的是库存文件上传）。如果计算问题仍然存在，请联系销售伙伴支持。
无论您是否参与亚马逊税务计算服务，除了计算、缴纳和报告义务范围内的所有税费之外，您还应负责确定自己的纳税义务。有关更多信息，请参阅我们的税务政策。

Product Tax Codes
Important: Information on this page does not constitute tax, legal, or other professional advice and must not be used as such. You should consult your professional advisers if you have questions.
Tax Calculation Services require both Product Tax Code (PTC) and jurisdiction settings to be configured for calculations to take effect.
Product taxability rules are applied by PTC and are specific to jurisdictions, as outlined in the Amazon Product Tax Code list. A PTC can be assigned at the item or default level.
If a PTC assignment is not assigned to the default or item levels, the tax calculation result will be non-taxable for the item(s) in the transaction using the "Always Non-taxable" A_GEN_NOTAX product tax code, resulting in a zero percent calculation.
Default level: The default PTC is set in your Tax Settings and is used to apply a single PTC assignment to multiple offers that do not have a specific item level PTC already assigned. If you use a custom rate, your PTC rule and rate will be overridden with your custom rate. Custom rate is not available in Canada.
To view or edit Default Product Tax Code:
In Seller Central, go to Settings.
Click Tax Settings.
Under Tax Calculation Rules use the drop-down next to Default Product Tax Code.
Select your Default Product Tax Code
Use the View Product Tax Codes link next to the drop down to review a complete list of PTC’s and associated rules for each
Read the Tax Methodology and Service Terms and check acknowledgment box
Click Save Settings
Item level: Your item level PTC is set in the items inventory page and is used to designate a specific PTC to the specific item it is assigned to. The item level PTC will be used before your default PTC assignment. Also, if you use a custom rate, your PTC rule and rate will be overridden with your custom rate. Custom rate is not available in Canada.
To view or edit item level product tax code:
Go to Manage Inventory
Click Edit for the individual product
This will take you to the Edit Product Info page
In the Offer tab locate the Tax Code field
Click into the field and select your item level product tax code from the drop down list
Click Save and finish
The following tools are available to assist with updating individual product detail pages:
To edit multiple listings in bulk use Inventory file upload.
To add a new listing use Add a Product tool.
How a Product Tax Code (PTC) is determined at the time of tax calculation
When a PTC is assigned at the seller-defined default level AND the item level, Amazon will use the item level tax code.
When a PTC is assigned at the default level but not at the item level, Amazon will use the seller-defined default PTC.
When a PTC is not assigned at the item or default level, a calculation will be made using the nontaxable PTC A_GEN_NOTAX.
Note: Custom Rate, if configured, will override the taxability rules of PTCs except for A_GEN_NOTAX. To learn more, see Custom Rates. Custom rate is not available in Canada.
Tax Calculation Setting updates will typically become effective within 15-20 minutes and do not apply to orders retroactively. If you notice unexpected tax calculations, check your settings (tax settings and item level) and inventory file upload for errors (if you used an inventory file upload). If the calculation issue persists, please contact seller support.
You are responsible for identifying your Tax obligations in addition to the calculation, remittance, and reporting of all taxes within your obligation, regardless of your participation in Amazon’s Tax Calculation Service. For more information, see our Tax Policies.
