PaperFork

Platforms and agent operators may want structured tax calculations without operating an open-source tool server themselves. PaperFork packages a confirmed substrate whose current research snapshot lists 261 skills across 172 jurisdictions. That breadth is a catalog count, not proof that every skill is current, complete or suitable for a taxpayer. The research also corrects the invention record: different components use different licenses, and the upstream team already offers a commercial hosted, warranted and filing-oriented layer. PaperFork therefore cannot claim an empty managed-hosting market or rely on a universal copyleft moat. Every component's license, source, version, authority and modification path is tracked separately. Tenant facts, jurisdiction selection, tax period, entity type, currency, assumptions and source evidence bind each call. Deterministic execution, integrity signature, practitioner review, customer approval, filing instruction, authority acknowledgment, payment and final tax treatment remain separate. A technical output is an estimate or calculation artifact, not tax advice, a return or guaranteed liability. Unsupported jurisdictions and stale rules fail closed. Success is transparent, reproducible integration with visible professional responsibility and correction—not automatic compliance, warranted advice or regulator acceptance.

A creator platform, talent agency, accounts-payable product or agent operator that needs structured tax-tool access with explicit jurisdiction and review controls.
