Source-referenced fiscal research across 118 mapped configurations. Filter by jurisdiction, calculation status, legal status and onshore or offshore setting.
118Mapped fiscal configurations
7Petroleum fiscal calculator families
5Australian state royalty systems
The catalogue maps 118 fiscal configurations across 27 jurisdictions and 4 cross-border arrangements. A mapped record is not a built calculator. Seven engine families have been reconciled against independent benchmark corpora. Five Australian state onshore engines have separate analytical and periodicity audits; the PNG historical chassis has not been campaign-reconciled. Filter by calculation status to distinguish calculator availability from legal status. Contract terms, overlays and applicable versions require project-level confirmation.
