Install taiwan-payroll

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

From the project's README

As published by supra126/taiwan-payroll in README.md.

開源的台灣勞健保勞退法定費用計算引擎。輸入薪資與身份,算出勞保(含就保)、健保、勞退、職災與二代健保補充保費的各方負擔——並涵蓋薪資所得扣繳、月中到職/離職破月、健保補充保費申報媒體檔,以及勞保老年給付試算。

  • 🧮 線上試算:https://taiwan-payroll.vercel.app(免安裝,瀏覽器直接算)
  • 🔌 三種介面:TypeScript(npm)、Python(PyPI,純 stdlib)、MCP server(給 AI 助理呼叫)
  • 📑 官方對證:級距表與費率逐級取自主管機關公告,計算結果對官方範例黃金向量逐位元驗證
  • 🔁 跨語言一致:TS 與 Python 讀同一份 data/、跑同一套 testdata/,結果逐位元相同
  • 📦 零執行期依賴:core 不帶任何 runtime 套件

定位是「計算引擎」而非「法遵保證」。 內建民國 113–115(2024–2026)年度官方參數。

安裝

npm install taiwan-payroll      # TypeScript / Node
pip install taiwan-payroll      # Python

快速上手

import { createPayrollEngine } from 'taiwan-payroll';

const engine = createPayrollEngine({ year: 2026 });
const r = engine.calculate({
  monthlySalary: 42000,
  identity: 'category1',
  dependents: 1,
  employmentInsurance: true,
  pensionSelfContribution: 0.06,
});

console.log(r.employee); // { labor: 1050, health: 1302, pensionSelf: 2520, total: 4872 }
console.log(r.employer.occupational); // 職災雇主負擔

二代健保補充保費與破月計算

// 補充保費(六類所得:bonus/parttime/professional/dividend/interest/rent)
engine.calculateSupplementary({ type: 'bonus', amount: 200000, monthlyInsuredSalary: 42000 });
// → { type: 'bonus', chargeable: 32000, rate: '0.0211', premium: 675 }

// 月中到職/離職(勞保/職保/勞退按日;健保採官方「月底歸屬」原則)
engine.calculateProrated({ monthlySalary: 29500, startDate: '2026-03-08' });
// → { ..., days: { insured: 23 }, healthCharged: true }

健保破月採「月底歸屬原則」:以月底所屬投保單位計收整月——到職當月計整月、離職當月不計。此為健保署實務規則(非按日、與 15 日分水嶺無關)。

申報媒體檔(健保補充保費)

由申報資料產生健保署「補充保險費明細申報檔」(CSV/Big5),涵蓋 6 類所得:獎金(62)、兼職薪資(63)、執行業務(65)、股利(66)、利息(67)、租金(68)。每個產生器皆以健保署官方範例逐位元驗證,TS 與 Python 結果一致。

import { generateSupplementaryBonusFiling } from 'taiwan-payroll';

const { filename, content } = generateSupplementaryBonusFiling({
  year: 2026,
  filingDate: '20260901', // 用於檔名
  unit: { taxId: '11111111', name: '甲公司', phone: '0227065866', email: 'a@b.tw', contactName: '王小明' },
  records: [
    { action: 'I', payDate: '20260615', payeeId: 'A123456789', payeeName: '李四',
      bonusAmount: 50000, insuredSalary: 31800, ytdBonusCumulative: 150000, unitCode: '123456789' },
  ],
});
// filename: 'DPR111111111150901001.csv'
// content : Unicode 字串;檔案實際為 Big5,存檔時請以 Big5 編碼寫出。
  • 獎金/兼職/執行業務/利息/租金:逐列補充保費由引擎計算。股利(generateSupplementaryDividendFiling)因含股票股利/雇主扣除等情形,逐列保費由呼叫端提供(另附便利函式 calcDividendPremium)。
  • 輸出為「資料檔」供以官方入口上傳。Big5 編碼:TS 由呼叫端編碼,Python 提供 to_big5_bytes()(core 維持零依賴)。
  • API 詳見文件站 /docs/api。

勞保老年給付試算

依勞保局官方公式試算三種老年給付(皆對官方數值/公式驗證、TS≡Python):

import { calcOldAgePension, calcOldAgeLumpSum, calcOldAgeSinglePayment, getYearData } from 'taiwan-payroll';
const d = getYearData(2026);
calcOldAgePension(d, { avgInsuredSalary: 32000, years: 35, months: 6 });     // 月領年金(擇優兩式,可提前/延後)
calcOldAgeLumpSum(d, { avgInsuredSalary: 30000, years: 10 });                // 老年一次金
calcOldAgeSinglePayment(d, { avgInsuredSalary: 30000, preSixtyYears: 20 });  // 一次請領(舊制基數)
  • 老年年金:擇優兩式(平均×年資×0.775%+3000 vs ×1.55%),提前/延後 claimOffsetMonths(±4%/年、上限 ±5 年(±20%));附 averageHighestInsuredSalary、statutoryClaimAge。
  • 老年一次金:年資每滿 1 年發 1 個月,逾 60 歲後年資最多 5 年。
  • 一次請領:基數制(前 15 年每年 1 基數、超過部分每年 2 基數、前 60 上限 45、合併上限 50),平均採退保前 36 個月。
  • 試算僅供參考,實際以勞保局核定為準。

架構

  • data/{year}.json — 單一事實來源,年度法規參數(級距表、費率),以 JSON Schema 驗證。
  • testdata/ — 語言無關的黃金測試向量(官方案例,含 source 出處),是跨語言行為一致性的根基。
  • packages/core — 零執行期依賴的 TypeScript 引擎。

其他語言與介面

  • Python:pip install taiwan-payroll,純 stdlib、API 對應 TS 版(PyPI)。
  • MCP server:讓 Claude 等 AI 助理直接呼叫試算。遠端免安裝端點 https://taiwan-payroll.simoko.workers.dev/mcp(Streamable HTTP),或本地 npx taiwan-payroll-mcp(stdio,npm)。
    • 上架於官方 MCP Registry(io.github.supra126/taiwan-payroll)、Smithery(一鍵安裝)與 Glama。
  • 線上計算機與完整 API:https://taiwan-payroll.vercel.app
