我正在开设一家nopcommerce网上商店，标准显示所有价格包括税（21％）。因此，购物车中显示的小计包含税。在客户决定购买产品并开始完成订单后，应检查客户的位置（通过送货地址）
我想要做的是当客户完成它应该扣除的订单（或者不取决于客户所在的国家/地区）的税收。
例如，当居住在荷兰时，不从总订单价格中扣除税款，但在美国居住时，应从总订单价格中扣除21％的税金。
我已尝试使用
中的nop commerce管理员中的某些设置 Configuration -> Settings -> Tax Settings
我目前的税务设置是：
Prices include tax: YES
Allow customers to select tax display type: NO
Tax display type: Including Tax
Display tax suffix: YES
Display all applied tax rates: YES
Hide zero tax: NO
Hide tax in order summary: NO
Force tax exclusion from order subtotal: NO
Tax based on: Shipping address
Country: Netherlands
Shipping is taxable: YES
Shipping price includes tax: YES
Payment method additional fee is taxable: YES
Payment method additional fee includes tax: YES
EU VAT enabled: NO
另外
Configuration -> Tax -> Tax Providers
Configuration -> Tax -> Tax Categories
税务提供者的选项是Fixed tax rate provider和Tax By Country & State & Zip（主要提供者）
我似乎找不到合适的设置。此外，我尝试通过完成订单时使用的OrderTotalCalculationService.cs类中的代码进行调试。但我无法真正找到让我感到震惊的正确代码。
我不确定这是设置问题还是代码问题。

这段代码似乎计算了订单流中购物车的总数。但我无法找到检查送货地址的部分，并在美国时从订单总额中扣除税款。有人知道代码检查税的位置吗？

除了 OrderTotalCalculationService 之外，您还应该查看 TaxService 。此外，按国家/地区分类插件应该足够灵活，以处理您提到的方案。

@TomAalbers
我启用了默认的税收插件（Tax.CountryStateZip）＆amp;成为主要的税务提供者。 我通过对免税的国家（现有）税收类别应用0％来配置插件。 对于我想要收税的国家，我已经设定了每个税种的百分比。
我希望这很清楚，如果不是，我可以用截图更新我的答案。
