#056: Implement Pluggable Rules Engine for Dynamic and Multi-Jurisdictional Tax Calculations

Category: [BACKEND]
Difficulty: ● HARD

Description

Implement a flexible tax calculation engine that allows organizations to define local tax rules and automatically deduct them from payroll amounts before on-chain distribution.

Advanced / Production Requirements (HARD Upgrade)

Implement a flexible and pluggable tax calculation rules engine. The engine must dynamically load tax modules based on the worker's jurisdiction (country, state, region) and employment type. The system should support versioned rules to ensure retro-active payroll audits run against the tax code that was active at the time of payment.

Acceptance Criteria

• Configurable tax rules (percentage, fixed amount).
• Automatic deduction logic in the payroll engine.
• Tax reports generated per organization for local compliance.
• Pluggable engine architecture dynamically importing jurisdiction modules.
• Temporal versioning of tax rules to handle retrospective audits.
• Comprehensive unit test suite covering complex edge tax brackets.
