All Implemented Interfaces:
Serializable
public final class FiscalParameters extends Object implements Serializable
Data class holding all fiscal parameters for a specific country or region.

This class encapsulates all the tax and fiscal parameters that vary by jurisdiction, including:

  • Tax rates (corporate, petroleum/resource, royalty)
  • Depreciation rules
  • Investment incentives (uplift, accelerated depreciation)
  • Loss carry-forward rules
  • Cost recovery limits

Supported Fiscal System Types

  • Concessionary: Company owns resources, pays taxes/royalties (e.g., Norway, UK, US)
  • Production Sharing Contract (PSC): State owns resources, company recovers costs and shares profit (e.g., Indonesia, Angola)
  • Service Contract: Company provides services for fee (e.g., Iraq, Iran)

Example Usage

// Create custom parameters
FiscalParameters params = FiscalParameters.builder("CustomCountry").corporateTaxRate(0.25)
    .resourceTaxRate(0.40).royaltyRate(0.10).depreciationYears(5).build();

// Or use predefined country
FiscalParameters norway = FiscalRegimeRegistry.getParameters("Norway");
