常见问题

Taxlocus 安全吗?

它在 1 项适用的基础检查中通过了 1 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端?

它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(1.0.0)于5个月前进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

TaxLocus Open Sales-Tax Dataset

Free, weekly-updated US sales-tax rate tables — the flat data behind TaxLocus, released as an open dataset for the community.

Data as of: 2026-05-19 · Refreshed weekly from the live TaxLocus corpus.

What this is

A clean, flat snapshot of US sales-tax rates and rules:

  • State base rates for all sales-tax states.
  • Local jurisdiction rates — ~14,000 counties, cities, parishes, boroughs, transit and special districts.
  • Economic-nexus thresholds — the per-state remote-seller registration triggers.
  • Taxability matrix — state × product-category taxable/exempt treatment.

Both CSV and JSON are provided for every table.

What this is *not*

This is the rate data only. The address-level lookup API, the polygon geometry that resolves an address to its jurisdiction stack, and the nexus tracking tools are the paid product at [taxlocus.com](https://taxlocus.com). This dataset will tell you the rate *for a named jurisdiction*; it will not tell you *which* jurisdictions a given street address falls in.

Payroll-tax open data (new — Plan 14)

Reference tables for US payroll tax — federal FICA/FUTA, state personal income tax (PIT) and SUTA wage bases, and local income tax where it exists (PA, OH, MD, IN, NYC, etc.). Same shape + CC-BY-4.0 licence; every row carries a citation_url to the authoritative source (IRS, state DOR, state UI agency) so any value can be verified or refreshed against the source. This is rate / reference data only — not a withholding-tax calculation engine, not the per-employer SUTA experience rate (which is state-assigned and not lookupable). Consumers compute their own withholding and take liability for it.

Local income tax coverage (3,662 rows, 8 states): PA (2,627 PSDs) · OH (890 munis: RITA + CCA + DOR self-administered) · IN (92 counties) · MD (24 counties) · MI (24 cities) · NY (NYC + Yonkers) · MO (KC + STL) · DE (Wilmington). The remaining ~8 states with some local income tax are not yet covered (KY, IA, OR, AL, CO, WV, KS, NJ-Newark); the other ~34 states have no local income tax at all. Read [`PAYROLL-COVERAGE.md`](./PAYROLL-COVERAGE.md) before relying on this data for withholding — it documents every gap and the disclaimer in detail.

payroll_reciprocity — state income-tax reciprocity agreements

Reciprocity exempts the non-resident state from withholding when an employee files the exemption form (e.g., PA REV-419, MD MW507).
