Frequently asked questions

为什么结果是"估算"而不是精确税率?

美国销售税按具体收货地址征收:州基准税率之上,还有县、市、特别税区的地方附加税,同一 ZIP 内不同街道都可能不同。本工具按 ZIP 前缀匹配州、套用州基准税率(2026 年 10 月数据),地方附加税无法覆盖——精确税率请用结账页或税务服务商的地址级查询。

ZIP 前缀是怎么对应到州的?

取 ZIP 前 3 位查内置映射表(覆盖主要城市区号)。查不到的 ZIP 请手动从下拉框选州——税率照样可以算。

税率可以改吗?

可以。州下拉框选定后会带出基准税率,旁边的输入框允许直接覆盖——比如你知道某地址的综合税率是 9.5%,直接填进去即可。

哪些州没有销售税?

阿拉斯加、特拉华、蒙大拿、新罕布什尔、俄勒冈五个州无州级销售税(阿拉斯加部分地方政府会征)。注意"无销售税"不等于"无税",各州还有其他税种。

跨境卖家需要代收美国销售税吗?

取决于"经济关联(economic nexus)":各州有销售额/订单数门槛,超过就要注册税号并代收代缴。这是税务合规问题,本工具只做税额估算,具体义务请咨询税务顾问。

我填的 ZIP 和金额会上传吗?

不会。全部计算在你的浏览器本地完成,页面不保存也不上传你输入的任何数据。

What does an US Sales Tax Calculator do?

US sales tax follows the ship-to address: each state sets a base rate and localities may add more, so the same state can have many rates.

Who is this for, and when is it useful?

Sellers quoting US consumers.

How do I use this US Sales Tax Calculator?

Enter a 5-digit ZIP and order amount for a state base-rate estimate; add local taxes manually and verify by address.

How should I interpret the results?

This tool estimates with statewide base rates only, excluding local add-ons; actual rates vary by address, verify before checkout.

Where is the work performed, and which services receive data?
