PolicyEngine

PolicyEngine is a non-profit organization based in the UK that develops free, open-source software for analyzing the economic impact of public policies. It focuses on computational policy analysis, allowing users to model tax and benefit reforms across various jurisdictions. The organization operates as a private company limited by guarantee and has a registered office in London. PolicyEngine offers a policy simulation platform that enables users to simulate policy changes at both household and societal levels. This platform estimates effects on poverty, inequality, and government budgets. Launched in January 2023, its US platform allows users to design custom reforms and assess outcomes across all 50 states and Washington, D.C. The organization also provides API access for developers to integrate its calculations into third-party applications and publishes research analyses on policy reforms. With a commitment to accessibility, PolicyEngine aims to support evidence-based policymaking without requiring technical expertise from users.
