Taiwanese employers running Odoo hit a wall the moment payroll needs to reflect local reality. Odoo Community ships no payroll engine at all, and Odoo Enterprise hr_payroll provides only a generic rule engine with a handful of country localizations — Taiwan is not one of them. That leaves HR teams hand-calculating Labor Insurance (勞保) and National Health Insurance (健保) contributions off the bracketed insured-salary tables, tracking the employer/employee/government split, computing the 6% Labor Pension (勞退) employer contribution, and applying income-tax withholding rules in spreadsheets — then keying results back into Odoo. It is slow, error-prone, and impossible to audit cleanly at month-end.

This build-to-order module extends Odoo's native HR and payroll framework with a Taiwan-specific localization layer rather than replacing it. We ship a proper Odoo app: a __manifest__.py declaring dependencies on hr and hr_payroll, new models.Model classes for the insured-salary grade tables, contribution-rate configuration, and pension records, plus computed fields using @api.depends so that changing an employee's insured-salary grade or department instantly recalculates the employer and employee portions. Salary rules are seeded as data records (hr.salary.rule / hr.salary.rule.category) wired into a TWD-denominated salary structure, so a payslip run resolves Labor Insurance, Health Insurance, labor pension, and income-tax withholding lines automatically from Python rule logic — no manual formulas.

Technically, the module adds Taiwan-specific HR fields (national ID / ARC number, insured-salary grade, dependents for NHI supplementary premium, hire and enrolment dates) to hr.employee via inheritance, guarded by ir.model.access.csv and record rules so payroll data stays scoped to HR and payroll roles. Views are delivered as XML (with OWL components where an interactive widget helps), and month-end statutory outputs — insurance schedules and withholding summaries — are produced as QWeb reports you can hand to the Bureau of Labor Insurance, NHI Administration, and tax authority. Contribution-rate and insured-salary tables are configuration data, so when the government revises the brackets you update records instead of editing code. Everything is reachable over Odoo's XML-RPC / JSON-RPC API for integration with attendance, time-off, or an external HR system.

Because this is build-to-order, you are not downloading a fixed listing from apps.odoo.com. After a short scoping call we confirm exact requirements — your entities, pay cadence, allowances, and which Odoo version and edition you run — and then build, test, and install the module for you. Typical delivery is one working week from confirmed scope. We support Odoo 17.0, 18.0, and 19.0, on Community or Enterprise, and hand over the full source and git repository at go-live.
