Taiwan Payroll Tax for Odoo
Monthly salary income-tax withholding, labor / health / pension integration and a year-end withholding statement
Run Taiwan monthly payroll directly in Odoo. This module computes the income-tax withholding (薪資所得扣繳) on every wage payment by either statutory Ministry of Finance method — the progressive withholding tax table (查表) or the fixed 5% method (定額) — folds in the employee-side Labor Insurance, Health Insurance and Labor Pension deductions from the companion insurance module, and produces a complete payslip with net pay, a payroll register and a year-end withholding declaration. Built on the Human Resources app with its own payslip and computation models, so it needs no Enterprise payroll. Compatible with Odoo 18 and Odoo 19, Community and Enterprise.
Income-Tax Withholding (薪資所得扣繳)
Two statutory methods per employee: the progressive monthly withholding table on taxable salary (gross less the salary allowance and one personal exemption per mouth — self plus each declared dependant — computed with the 速算 progressive-difference), or the flat 5% fixed method above the monthly tax-free threshold. Non-resident employees are withheld at the flat non-resident rate on the whole payment. The bracket table is an editable model — adjust it as the law changes.
Labor / Health / Pension Integration
The employee-side Labor Insurance (勞保), Employment Insurance (就保), National Health Insurance (健保) and any voluntary Labor Pension self-contribution (勞退自提) are pulled from the companion insurance module's exact graded engine and combined into the payslip, so net pay and total deductions are complete in a single payroll run.
Payroll Run & Register
Populate employees, compute insurance plus withholding plus net pay per worker, review run totals, and export the payroll register as CSV or Excel. Each run is sequenced, tracked through Draft / Computed / Done and carries a full chatter audit trail.
Year-End Withholding Statement
Aggregate a tax year's payslips per employee — income code 50 (salary), gross paid and tax withheld, keyed by National ID / ARC — into the 各類所得扣繳暨免扣繳憑單 declaration media file you file with the National Taxation Bureau, with a built-in Taiwan ID checksum validator.
BYOK and privacy
The pure-Python computation engine is fully unit tested. It produces the statutory figures, the payroll register and the year-end withholding media file; you reconcile and file them through the National Taxation Bureau channel with your own credentials (BYOK). No employee data leaves Odoo and nothing is transmitted to any third party. All rates, allowances, exemptions, thresholds and the withholding table carry the current 2026 statutory defaults and are fully editable — confirm them against the latest official Ministry of Finance / National Taxation Bureau guidance before running live payroll.
