概览

AI 生成的概览

根据各州销售额判断远程卖家需在美国哪些州注册销售税，并列出各州经济关联门槛及即将发生的变化。

可以做什么: 该服务器评估远程卖家的经济关联：输入某期间各州的美元销售额和交易笔数后，报告哪些州要求注册以征收销售税。它还会列出各州的经济关联门槛，包括金额与交易笔数标准、计量期间、市场平台规则和官方来源，并按日期窗口列出即将或近期发生的门槛变化。一个免费的能力工具显示覆盖范围、数据最后核对日期及相关服务器。
适用场景: 适合在线卖家、会计师或财务团队快速了解美国各州销售税注册义务，或跟踪门槛变化，例如某些州取消交易笔数标准。
运行要求: 远程 streamable HTTP 端点；未声明身份验证、环境变量或请求头。需要能访问该端点的网络连接。

安装前请注意

提交用于关联检查的销售数据会发送到第三方远程服务，请考虑这些数据是否敏感。结果仅供参考，注册或征税前应依据各州官方来源核实。

Lists coverage (45 sales tax states plus DC, and the 5 states with no statewide sales tax), the date the data was last checked, and related Nero Labs Rules servers. Free.

无需输入参数。

check_economic_nexus

Checks which US states a remote seller (no office, staff or stock in the state) must register in to collect sales tax, from its sales into each state. Give sales_by_state with the dollar sales and number of transactions (orders) per state, the period those figures cover, and whether they include sales made through marketplaces such as Amazon or Etsy. Returns states where the seller is over the economic nexus threshold (must register), states close to it (80 percent or more), states under it, and for each the threshold, the measurement period the state uses, what sales count (gross, retail or taxable only), whether marketplace sales count, when registration must happen, and the state revenue department source. Unclear cases give the SAFE answer (treated as over) with what it depends on. Free.
